Introduction There is a lot of software freely available for Unix based systems, which usually runs on NetBSD and other Unix-flavoured systems, too, sometimes with some modifications. The NetBSD Packages Collection (pkgsrc) incorporates any such changes necessary to make that software run, and makes the installation (and de-installation) of the software package easy by means of a single command. Once the software has been built, it is manipulated with the pkg_* tools so that installation and de-installation, printing of an inventory of all installed packages and retrieval of one-line comments or more verbose descriptions are all simple. pkgsrc currently contains several thousand packages, including: * www/apache - The Apache web server * www/mozilla - The Mozilla web browser * meta-pkgs/gnome - The GNOME Desktop Environment * meta-pkgs/kde3 - The K Desktop Environment ...just to name a few. pkgsrc has built-in support for handling varying dependencies, such as pthreads and X11, and extended features such as IPv6 support on a range of platforms. pkgsrc was derived from FreeBSD's ports system, and initially developed for NetBSD only. Since then, pkgsrc has grown a lot, and now supports the following platforms: * Darwin (Mac OS X) * DragonFlyBSD * FreeBSD * Microsoft Windows, via Interix * IRIX * Linux * NetBSD (of course) * Tru64 (Digital UNIX, OSF1) * OpenBSD * Solaris 1.2. Overview This document is divided into two parts. The first, The pkgsrc user's guide, describes how one can use one of the packages in the Package Collection, either by installing a precompiled binary package, or by building one's own copy using the NetBSD package system. The second part, The pkgsrc developer's guide, explains how to prepare a package so it can be easily built by other NetBSD users without knowing about the package's building details. This document is available in various formats: * HTML * PDF * PS * TXT 1.3. Terminology There has been a lot of talk about "ports", "packages", etc. so far. Here is a description of all the terminology used within this document. Package A set of files and building instructions that describe what's necessary to build a certain piece of software using pkgsrc. Packages are traditionally stored under /usr/pkgsrc. The NetBSD package system This is the former name of "pkgsrc". It is part of the NetBSD operating system and can be bootstrapped to run on non-NetBSD operating systems as well. It handles building (compiling), installing, and removing of packages. Distfile This term describes the file or files that are provided by the author of the piece of software to distribute his work. All the changes necessary to build on NetBSD are reflected in the corresponding package. Usually the distfile is in the form of a compressed tar-archive, but other types are possible, too. Distfiles are usually stored below /usr/pkgsrc/distfiles. Port This is the term used by FreeBSD and OpenBSD people for what we call a package. In NetBSD terminology, "port" refers to a different architecture. Precompiled/binary package A set of binaries built with pkgsrc from a distfile and stuffed together in a single .tgz file so it can be installed on machines of the same machine architecture without the need to recompile. Packages are usually generated in /usr/pkgsrc/packages; there is also an archive on ftp.NetBSD.org. Sometimes, this is referred to by the term "package" too, especially in the context of precompiled packages. Program The piece of software to be installed which will be constructed from all the files in the Distfile by the actions defined in the corresponding package. 1.4. Typography When giving examples for commands, shell prompts are used to show if the command should/can be issued as root, or if "normal" user privileges are sufficient. We use a # for root's shell prompt, and a % for users' shell prompt, assuming they use the C-shell or tcsh. The pkgsrc user's guide Table of Contents 2. Where to get pkgsrc 2.1. As tar file 2.2.

Where to get pkgsrc Table of Contents 2.1. As tar file 2.2. Via SUP 2.3. Via CVS There are three ways to get pkgsrc. Either as a tar file, via SUP, or via CVS. All three ways are described here. 2.1. As tar file To get pkgsrc going, you need to get the pkgsrc.tar.gz file from ftp.NetBSD.org and unpack it into /usr/pkgsrc. 2.2. Via SUP As an alternative to the tar file, you can get pkgsrc via the Software Update Protocol, SUP. To do so, make sure your supfile has a line release=pkgsrc in it, see the examples in /usr/share/examples/supfiles, and that the /usr/ pkgsrc directory exists. Then, simply run sup -v /path/to/your/supfile. 2.3. Via CVS To get pkgsrc via CVS, make sure you have "cvs" installed. To do an initial (full) checkout of pkgsrc, do the following steps: % setenv CVSROOT anoncvs@anoncvs.NetBSD.org:/cvsroot % setenv CVS_RSH ssh % cd /usr % cvs checkout -P pkgsrc This will create the pkgsrc directory in your /usr, and all the package source will be stored under /usr/pkgsrc. To update pkgsrc after the initial checkout, make sure you have CVS_RSH set as above, then do: % cd /usr/pkgsrc % cvs -q update -dP Please also note that it is possible to have multiple copies of the pkgsrc hierarchy in use at any one time - all work is done relatively within the pkgsrc tree. Chapter 3. Using pkgsrc on systems other than NetBSD Table of Contents 3.1. Bootstrapping pkgsrc 3.2. Platform specific notes 3.2.1. Darwin (Mac OS X) 3.2.2. FreeBSD 3.2.3. Interix 3.2.4. IRIX 3.2.5. Linux 3.2.6. OpenBSD 3.2.7. Solaris 3.1. Bootstrapping pkgsrc For operating systems other than NetBSD, we provide a bootstrap kit to build the required tools to use pkgsrc on your platform. Besides support for native NetBSD, pkgsrc and the bootstrap kit have support for the following operating systems: * Darwin (Mac OS X) * DragonFlyBSD * FreeBSD * Interix (Windows 2000, XP, 2003) * IRIX * Linux * OpenBSD * Solaris * Tru64 (Digital UNIX/OSF1) Support for other platforms is under development. Installing the bootstrap kit should be as simple as: # env CVS_RSH=ssh cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout pkgsrc # cd pkgsrc/bootstrap # ./bootstrap See Chapter 2, Where to get pkgsrc for other ways to get pkgsrc before bootstrapping. The given bootstrap command will use the defaults of /usr/pkg for the prefix where programs will be installed in, and /var/db/pkg for the package database directory where pkgsrc will do its internal bookkeeping. However, these can also be set using command-line arguments. Binary packages for the pkgsrc tools and an initial set of packages is available for supported platforms. An up-to-date list of these can be found on www.pkgsrc.org. 3.2. Platform specific notes Here are some platform-specific notes you should be aware of. 3.2.1. Darwin (Mac OS X) Darwin 5.x and 6.x are supported. There are two methods of using pkgsrc on Mac OS X, by using a disk image, or a UFS partition. Before you start, you will need to download and install the Mac OS X Developer Tools from Apple's Developer Connection. See http://developer.apple.com/macosx/ for details. Also, make sure you install X11 for Mac OS X and the X11 SDK from http://www.apple.com/macosx/x11/download/ if you intend to build packages that use the X11 Window System. If you already have a UFS partition, or have a spare partition that you can format as UFS, it is recommended to use that instead of the disk image. It'll be somewhat faster and will mount automatically at boot time, where you must manually mount a disk image. Note You cannot use a HFS+ file system for pkgsrc, because pkgsrc currently requires the filesystem to be case-sensitive, and HFS+ is not. 3.2.1.1. Using a disk image Create the disk image: # cd pkgsrc/bootstrap # ./ufsdiskimage create ~/Documents/NetBSD 512 # megabytes - season to taste # ./ufsdiskimage mount ~/Documents/NetBSD # sudo chown `id -u`:`id -g` /Volumes/NetBSD That's it! 3.2.1.2. Using a UFS partition By default, /usr will be on your root file system, normally HFS+. It is possible to use the default prefix of /usr/pkg by symlinking /usr/pkg to a directory on a UFS file system. Obviously, another symlink is required if you want to place the package database directory outside the prefix. e.g. # ./bootstrap --pkgdbdir /usr/pkg/pkgdb --pkgsrcdir /Volumes/ufs/pkgsrc If you created your partitions at the time of installing Mac OS X and formatted the target partition as UFS, it should automatically mount on /Volumes/ when the machine boots. If you are (re)formatting a partition as UFS, you need to ensure that the partition map correctly reflects "Apple_UFS" and not "Apple_HFS". The problem is that none of the disk tools will let you touch a disk that is booted from. You can unmount the partition, but even if you newfs it, the partition type will be incorrect and the automounter won't mount it. It can be mounted manually, but it won't appear in Finder. You'll need to boot off of the OS X Installation (User) CD. When the Installation program starts, go up to the menu and select Disk Utility. Now, you will be able to select the partition you want to be UFS, and Format it Apple UFS. Quit the Disk Utility, quit the installer which will reboot your machine. The new UFS file system will appear in Finder. Be aware that the permissions on the new file system will be writable by root only. This note is as of 10.2 (Jaguar) and applies to earlier versions. Hopefully Apple will fix Disk Utility in 10.3 (Panther). 3.2.2. FreeBSD FreeBSD 4.7 and 5.0 have been tested and are supported, other versions may work. Care should be taken so that the tools that this kit installs do not conflict with the FreeBSD userland tools. There are several steps: 1. FreeBSD stores its ports pkg database in /var/db/pkg. It is therefore recommended that you choose a different location (e.g. /usr/pkgdb) by using the --pkgdbdir option to the bootstrap script. 2. If you do not intend to use the FreeBSD ports tools, it's probably a good idea to move them out of the way to avoid confusion, e.g. # cd /usr/sbin # mv pkg_add pkg_add.orig # mv pkg_create pkg_create.orig # mv pkg_delete pkg_delete.orig # mv pkg_info pkg_info.orig 3. An example /etc/mk.conf file will be placed in /etc/mk.conf.example file when you use the bootstrap script. 3.2.3. Interix Interix is a POSIX compatible subsystem for the Windows NT kernel, providing a Unix-like environment with a tighter kernel integration than available with Cygwin. It is part of the Windows Services for Unix package, available for free for any licensed copy of Windows 2000, XP (not including XP Home), or 2003. SFU can be downloaded from http://www.microsoft.com/windows/sfu/. Services for Unix 3.5, current as of this writing, has been tested. 3.0 or 3.1 may work, but are not officially supported. (The main difference in 3.0/3.1 is lack of pthreads.) 3.2.3.1. When installing Interix/SFU At an absolute minimum, the following packages must be installed from the Windows Services for Unix 3.5 distribution in order to use pkgsrc: * Utilities -> Base Utilities * Interix GNU Components -> (all) * Remote Connectivity * Interix SDK When using pkgsrc on Interix, DO NOT install the Utilities subcomponent "UNIX Perl". That is Perl 5.6 without shared module support, installed to /usr/local, and will only cause confusion. Instead, install Perl 5.8 from pkgsrc (or from a binary package). The Remote Connectivity subcomponent "Windows Remote Shell Service" does not need to be installed, but Remote Connectivity itself should be installed in order to have a working inetd. Finally, during installation you may be asked whether to enable setuid behavior for Interix programs, and whether to make pathnames default to case-sensitive. Setuid should be enabled, and case-sensitivity MUST be enabled. (Without case-sensitivity, a large number of packages including perl will not build.) 3.2.3.2. What to do if Interix/SFU is already installed If SFU is already installed and you wish to alter these settings to work with pkgsrc, note the following things. * To uninstall UNIX Perl, use Add/Remove Programs, select Microsoft Windows Services for UNIX, then click Change. In the installer, choose Add or Remove, then uncheck Utilities->UNIX Perl. * To enable case-sensitivity for the filesystem, run REGEDIT.EXE, and change the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\kernel Set the DWORD value "obcaseinsensitive" to 0; then reboot. * To enable setuid binaries (optional), run REGEDIT.EXE, and change the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Services for UNIX Set the DWORD value "EnableSetuidBinaries" to 1; then reboot. 3.2.3.3. Important notes for using pkgsrc The package imanager (either the pkgsrc "su" user, or the user running "pkg_add") must be a member of the local Administrators group. Such a user must also be used to run the bootstrap. This is slightly relaxed from the normal pkgsrc requirement of "root". The package manager should use a umask of 002. "make install" will automatically complain if this is not the case. This ensures that directories written in /var/db/pkg are Administrators-group writeable. The popular Interix binary packages from http://www.interopsystems.com/ use an older version of pkgsrc's pkg_* tools. Ideally, these should NOT be used in conjunction with pkgsrc. If you choose to use them at the same time as the pkgsrc packages, ensure that you use the proper pkg_* tools for each type of binary package. The TERM setting used for DOS-type console windows (including those invoked by the csh and ksh startup shortcuts) is "interix". Most systems don't have a termcap/terminfo entry for it, but the following .termcap entry provides adequate emulation in most cases: interix:kP=\E[S:kN=\E[T:kH=\E[U:dc@:DC@:tc=pcansi: 3.2.4. IRIX You will need a working C compiler, either gcc or SGI's MIPS and MIPSpro compiler (cc/c89). Please set the CC environment variable according to your preference. If you do not have a license for the MIPSpro compiler suite, you can download a gcc tardist file from http://freeware.sgi.com/. Please note that you will need IRIX 6.5.17 or higher, as this is the earliest version of IRIX providing support for if_indextoname(3), if_nametoindex(3), etc. At this point in time, pkgsrc only supports one ABI at a time. That is, you can not switch between the old 32-bit ABI, the new 32-bit ABI and the 64-bit ABI. If you start out using "abi=n32", that's what all your packages will be built with. Therefore, please make sure that you have no conflicting CFLAGS in your environment or the /etc/mk.conf. Particularly, make sure that you do not try to link n32 object files with lib64 or vice versa. Check your /etc/ compiler.defaults! If you have the actual pkgsrc tree mounted via NFS from a different host, please make sure to set WRKOBJDIR to a local directory, as it appears that IRIX linker occasionally runs into issues when trying to link over a network mounted filesystem. The bootstrapping process should set all the right options for programs such as imake(1), but you may want to set some options depending on your local setup. Please see pkgsrc/mk/defaults/mk.conf and, of course, your compiler's man pages for details. If you are using SGI's MIPSPro compiler, please set PKGSRC_COMPILER=mipspro in /etc/mk.conf. Otherwise, pkgsrc will assume you are using gcc and may end up passing invalid flags to the compiler. Note that bootstrap should create an appropriate mk.conf.example by default. If you have both the MIPSPro compiler chain installed as well as gcc, but want to make sure that MIPRPro is used, please set your PATH to not include the location of gcc (often /usr/freeware/bin), and (important) pass the '--preserve-path' flag. 3.2.5. Linux Some versions of Linux (for example Debian GNU/Linux) need either libtermcap or libcurses (libncurses). Installing the distributions libncurses-dev package (or equivalent) should fix the problem. pkgsrc supports both gcc (GNU Compiler Collection) and icc (Intel C++ Compiler). gcc is the default. icc 8.0 and 8.1 on i386 have been tested. To bootstrap using icc, assuming the default icc installation directory: env CC=/opt/intel_cc_80/bin/icc LDFLAGS=-static-libcxa \ ac_cv___attribute__=yes ./bootstrap Note icc 8.1 needs the `-i-static' argument instead of -static-libcxa. icc supports __attribute__, but the GNU configure test uses a nested function, which icc does not support. #undef'ing __attribute__ has the unfortunate side-effect of breaking many of the Linux header files, which cannot be compiled properly without __attribute__. The test must be overridden so that __attribute__ is assumed supported by the compiler. After bootstrapping, you should set PKGSRC_COMPILER in /etc/mk.conf: PKGSRC_COMPILER=icc The default installation directory for icc is /opt/intel_cc_80, which is also the pkgsrc default. If you have installed it into a different directory, set ICCBASE in /etc/mk.conf: ICCBASE=/opt/icc pkgsrc uses the static linking method of the runtime libraries provided by icc, so binaries can be run on other systems which do not have the shared libraries installed. Libtool, however, extracts a list of libraries from the ld(1) command run when linking a C++ shared library and records it, throwing away the -Bstatic and -Bdynamic options interspersed between the libraries. This means that libtool-linked C++ shared libraries will have a runtime dependency on the icc libraries until this is fixed in libtool. 3.2.6. OpenBSD OpenBSD 3.0 and 3.2 are tested and supported. Care should be taken so that the tools that this kit installs do not conflict with the OpenBSD userland tools. There are several steps: 1. OpenBSD stores its ports pkg database in /var/db/pkg. It is therefore recommended that you choose a different location (e.g. /usr/pkgdb) by using the --pkgdbdir option to the bootstrap script. 2. If you do not intend to use the OpenBSD ports tools, it's probably a good idea to move them out of the way to avoid confusion, e.g. # cd /usr/sbin # mv pkg_add pkg_add.orig # mv pkg_create pkg_create.orig # mv pkg_delete pkg_delete.orig # mv pkg_info pkg_info.orig 3. An example /etc/mk.conf file will be placed in /etc/mk.conf.example file when you use the bootstrap script. OpenBSD's make program uses /etc/mk.conf as well. You can work around this by enclosing all the pkgsrc specific parts of the file with: .ifdef BSD_PKG_MK # pkgsrc stuff, e.g. insert defaults/mk.conf or similar here .else # OpenBSD stuff .endif 3.2.7. Solaris Solaris 2.6 through 9 are supported on both x86 and sparc. You will need a working C compiler. Both gcc 2.95.3 and Sun WorkShop 5 have been tested. The following packages are required on Solaris 8 for the bootstrap process and to build packages. * SUNWsprot * SUNWarc * SUNWbtool * SUNWtoo * SUNWlibm Please note the use of GNU binutils on Solaris is not supported. 3.2.7.1. If you are using gcc It makes life much simpler if you only use the same gcc consistently for building all packages. It is recommended that an external gcc be used only for bootstrapping, then either build gcc from lang/gcc or install a binary gcc package, then remove gcc used during bootstrapping. Binary packages of gcc can be found through http://www.sun.com/bigadmin/common/ freewareSearch.html. 3.2.7.2. If you are using Sun WorkShop You will need at least the following packages installed (from WorkShop 5.0) * SPROcc - Sun WorkShop Compiler C 5.0 * SPROcpl - Sun WorkShop Compiler C++ 5.0 * SPROild - Sun WorkShop Incremental Linker * SPROlang - Sun WorkShop Compilers common components You should set CC, CXX and optionally, CPP in /etc/mk.conf, eg. CC= cc CXX= CC CPP= /usr/ccs/lib/cpp You may also want to build 64-bit binaries, eg. CFLAGS= -xtarget=ultra -xarch=v9 Whichever compiler you use, please ensure the compiler tools and your $prefix are in your PATH. This includes /usr/ccs/{bin,lib} and eg. /usr/pkg/{bin,sbin}.

Building packages from source 4.2.1. Requirements 4.2.2. Fetching distfiles 4.2.3. How to build and install 4.2.4. Selecting the compiler 4.1. Working with binary packages This section describes how to find, retrieve and install a precompiled binary package that someone else already prepared for your type of machine. 4.1.1. Where to get binary packages Precompiled packages are stored on ftp.NetBSD.org and its mirrors in the directory /pub/NetBSD/packages/// for anonymous FTP access. OSVERSION is the NetBSD version (uname -r), ARCH is the architecture (uname -p ). In that directory, there is a subdirectory for each category plus a subdirectory All which includes the actual binaries in .tgz files. The category subdirectories use symbolic links to those files (this is the same directory layout as in /usr/pkgsrc/packages). This same directory layout applies for CDROM distributions, only that the directory may be rooted somewhere else, probably somewhere below /cdrom. Please consult your CDROMs documentation for the exact location. 4.1.2. How to use binary packages If you have the files on a CDROM or downloaded them to your hard disk, you can install them with the following command (be sure to su to root first): # pkg_add /path/to/package.tgz If you have FTP access and you don't want to download the packages via FTP prior to installation, you can do this automatically by giving pkg_add an FTP URL: # pkg_add ftp://ftp.NetBSD.org/pub/NetBSD/packages///All/package.tgz Note that any prerequisite packages needed to run the package in question will be installed, too, assuming they are present where you install from. To save some typing, you can set the PKG_PATH environment variable to a semicolon separated list of paths (including remote URLs); trailing slashes are not allowed. Additionally to the All directory there exists a vulnerable directory to which binary packages with known vulnerabilities are moved, since removing them could cause missing dependencies. To use these packages, add the vulnerable directory to your PKG_PATH. However, you should run security/audit-packages regularly, and especially after installing new packages, and verify that the vulnerabilities are acceptable for your configuration. An example PKG_PATH would be: ftp://ftp.NetBSD.org/pub/NetBSD/packages///All;ftp:/ /ftp.NetBSD.org/pub/NetBSD/packages///vulnerable Please note that semicolon (';') is a shell meta-character, so you'll probably have to quote it. After you've installed packages, be sure to have /usr/pkg/bin and /usr/pkg/sbin in your PATH so you can actually start the just installed program. 4.1.3. A word of warning Please pay very careful attention to the warnings expressed in the pkg_add(1) manual page about the inherent dangers of installing binary packages which you did not create yourself, and the security holes that can be introduced onto your system by indiscriminate adding of such files. 4.2. Building packages from source This assumes that the package is already in pkgsrc. If it is not, see Part II, "The pkgsrc developer's guide" for instructions how to create your own packages. 4.2.1. Requirements To build packages from source on a NetBSD system the "comp" and the "text" distribution sets must be installed. If you want to build X11 related packages the "xbase" and "xcomp" distribution sets are required, too. 4.2.2. Fetching distfiles The first step for building a package is downloading the distfiles (i.e. the unmodified source). If they have not yet been downloaded, pkgsrc will fetch them automatically. You can overwrite some of the major distribution sites to fit to sites that are close to your own. Have a look at pkgsrc/mk/defaults/mk.conf to find some examples ? in particular, look for the MASTER_SORT, MASTER_SORT_REGEX and INET_COUNTRY definitions. This may save some of your bandwidth and time. You can change these settings either in your shell's environment, or, if you want to keep the settings, by editing the /etc/mk.conf file, and adding the definitions there. If you don't have a permanent Internet connection and you want to know which files to download, make fetch-list will tell you what you'll need. Put these distfiles into /usr/pkgsrc/distfiles. 4.2.3. How to build and install Assuming that the distfile has been fetched (see previous section), become root and change into the relevant directory and running make. For example, type % cd misc/figlet % make at the shell prompt to build the various components of the package, and # make install to install the various components into the correct places on your system. Installing the package on your system requires you to be root. However, pkgsrc has a just-in-time-su feature, which allows you to only become root for the actual installation step Taking the figlet utility as an example, we can install it on our system by building as shown in Appendix B, Build logs. The program is installed under the default root of the packages tree - /usr/ pkg. Should this not conform to your tastes, set the LOCALBASE variable in your environment, and it will use that value as the root of your packages tree. So, to use /usr/local, set LOCALBASE=/usr/local in your environment. Please note that you should use a directory which is dedicated to packages and not shared with other programs (ie, do not try and use LOCALBASE=/usr). Also, you should not try to add any of your own files or directories (such as src/, obj/, or pkgsrc/) below the LOCALBASE tree. This is to prevent possible conflicts between programs and other files installed by the package system and whatever else may have been installed there. Some packages look in /etc/mk.conf to alter some configuration options at build time. Have a look at pkgsrc/mk/defaults/mk.conf to get an overview of what will be set there by default. Environment variables such as LOCALBASE can be set in /etc/mk.conf to save having to remember to set them each time you want to use pkgsrc. Occasionally, people want to "look under the covers" to see what is going on when a package is building or being installed. This may be for debugging purposes, or out of simple curiosity. A number of utility values have been added to help with this. 1. If you invoke the make(1) command with PKG_DEBUG_LEVEL=2, then a huge amount of information will be displayed. For example, make patch PKG_DEBUG_LEVEL=2 will show all the commands that are invoked, up to and including the "patch" stage. 2. If you want to know the value of a certain make(1) definition, then the VARNAME definition should be used, in conjunction with the show-var target. e.g. to show the expansion of the make(1) variable LOCALBASE: % make show-var VARNAME=LOCALBASE /usr/pkg % If you want to install a binary package that you've either created yourself (see next section), that you put into pkgsrc/packages manually or that is located on a remote FTP server, you can use the "bin-install" target. This target will install a binary package - if available - via pkg_add(1), else do a make package. The list of remote FTP sites searched is kept in the variable BINPKG_SITES, which defaults to ftp.NetBSD.org. Any flags that should be added to pkg_add(1) can be put into BIN_INSTALL_FLAGS. See pkgsrc/mk/defaults/mk.conf for more details. A final word of warning: If you setup a system that has a non-standard setting for LOCALBASE, be sure to set that before any packages are installed, as you can not use several directories for the same purpose. Doing so will result in pkgsrc not being able to properly detect your installed packages, and fail miserably. Note also that precompiled binary packages are usually built with the default LOCALBASE of /usr/pkg, and that you should not install any if you use a non-standard LOCALBASE. 4.2.4. Selecting the compiler By default, pkgsrc will use GCC to build packages. This may be overridden by setting the following variables in /etc/mk.conf: PKGSRC_COMPILER: This is a list of values specifying the chain of compilers to invoke when building packages. Valid values are: * distcc: distributed C/C++ (chainable) * ccache: compiler cache (chainable) * gcc: GNU C/C++ Compiler * mipspro: Silicon Graphics, Inc. MIPSpro (n32/n64) * mipspro: Silicon Graphics, Inc. MIPSpro (o32) * sunpro: Microsystems, Inc. WorkShip/Forte/Sun ONE Studio The default is "gcc". You can use ccache and/or distcc with an appropriate PKGSRC_COMPILER setting, e.g. "ccache gcc". This variable should always be terminated with a value for a real compiler. GCC_REQD: This specifies the minimum version of GCC to use when building packages. If the system GCC doesn't satisfy this requirement, then pkgsrc will build and install one of the GCC packages to use instead. Chapter 5. Configuring pkgsrc Table of Contents 5.1. Selecting Build Options 5.1. Selecting Build Options Some packages have build time options, usually to select between different dependencies, enable optional support for big dependencies or enable experimental features. To see which options, if any, a package supports, and which options are mutually exclusive, run make show-options, for example: The following options are supported by this package: ssl Enable SSL support. Exactly one of the following gecko options is required: firefox Use firefox as gecko rendering engine. mozilla Use mozilla as gecko rendering engine. At most one of the following database options may be selected: mysql Enable support for MySQL database. pgsql Enable support for PostgreSQL database. These options are enabled by default: firefox These options are currently enabled: mozilla ssl The following variables can be defined in /etc/mk.conf to select which options to enable for a package: PKG_DEFAULT_OPTIONS, which can be used to select or disable options for all packages that support them, and PKG_OPTIONS.pkgbase, which can be used to select or disable options specifically for package pkgbase . Options listed in these variables are selected, options preceded by "-" are disabled. The following settings are consulted in the order given, and the last setting that selects or disables an option is used: 1. the default options as suggested by the package maintainer 2. the options implied by the settings of legacy variables (see below) 3. PKG_DEFAULT_OPTIONS 4. PKG_OPTIONS.pkgbase For groups of mutually exclusive options, the last option selected is used, all others are automatically disabled. If an option of the group is explicitly disabled, the previously selected option, if any, is used. It is an error if no option from a required group of options is selected, and building the package will fail. Before the options framework was introduced, build options were selected by setting a variable in /etc/mk.conf for each option. To ease transition to the options framework for the user, these legacy variables are converted to the appropriate options setting automatically. A warning is issued to prompt the user to update /etc/mk.conf to use the options framework directly. Support for these legacy variables will be removed eventually. Chapter 6.

Building a partial set of packages 6.3.8. Uploading results of a bulk build 6.4. Creating a multiple CD-ROM packages collection 6.4.1. Example of cdpack 6.1. Building a single binary package Once you have built and installed a package, you can create a binary package which can be installed on another system with pkg_add(1) This saves having to build the same package on a group of hosts and wasting CPU time. It also provides a simple means for others to install your package, should you distribute it. To create a binary package, change into the appropriate directory in pkgsrc, and run make package: # cd misc/figlet # make package This will build and install your package (if not already done), and then build a binary package from what was installed. You can then use the pkg_* tools to manipulate it. Binary packages are created by default in /usr/pkgsrc/packages, in the form of a gzipped tar file. See Section B.2, "Packaging figlet" for a continuation of the above misc/figlet example. See Chapter 17, Submitting and Committing for information on how to submit such a binary package. 6.2. Settings for creation of binary packages See Section 14.3, "Other helpful targets". 6.3. Doing a bulk build of all packages If you want to get a full set of precompiled binary packages, this section describes how to get them. Beware that the bulk build will remove all currently installed packages from your system! Having an FTP server configured either on the machine doing the bulk builds or on a nearby NFS server can help to make the packages available to everyone. See ftpd(8) for more information. If you use a remote NFS server's storage, be sure to not actually compile on NFS storage, as this slows things down a lot. 6.3.1. Configuration 6.3.1.1. /etc/mk.conf You may want to set variables in /etc/mk.conf. Look at pkgsrc/mk/defaults/ mk.conf for details of the default settings. You will want to ensure that ACCEPTABLE_LICENSES meet your local policy. As used in this example, _ACCEPTABLE=yes accepts all licenses. PACKAGES?= ${_PKGSRCDIR}/packages/${MACHINE_ARCH} WRKOBJDIR?= /usr/tmp/pkgsrc # build here instead of in pkgsrc BSDSRCDIR= /usr/src BSDXSRCDIR= /usr/xsrc # for x11/xservers OBJHOSTNAME?= yes # use work.`hostname` FAILOVER_FETCH= yes # insist on the correct checksum PKG_DEVELOPER?= yes _ACCEPTABLE= yes 6.3.1.2. build.conf In pkgsrc/mk/bulk, copy build.conf-example to build.conf and edit it, following the comments in that file. This is the config file that determines where log files are generated after the build, where to mail the build report to, where your pkgsrc tree is located and the user to which user to su(8) to do a cvs update. 6.3.1.3. pre-build.local It is possible to configure the bulk build to perform certain site specific tasks at the end of the pre-build stage. If the file pre-build.local exists in /usr/pkgsrc/mk/bulk, it will be executed (as a sh(1) script) at the end of the usual pre-build stage. An example use of pre-build.local is to have the line: # echo "I do not have enough disk space to build this pig." \ > pkgsrc/misc/openoffice/$BROKENF to prevent the system from trying to build a particular package which requires nearly 3 GB of disk space. 6.3.2. Other environmental considerations As /usr/pkg will be completely deleted at the start of bulk builds, make sure your login shell is placed somewhere else. Either drop it into /usr/local/bin (and adjust your login shell in the passwd file), or (re-)install it via pkg_add(1) from /etc/rc.local, so you can login after a reboot (remember that your current process won't die if the package is removed, you just can't start any new instances of the shell any more). Also, if you use NetBSD earlier than 1.5, or you still want to use the pkgsrc version of ssh for some reason, be sure to install ssh before starting it from rc.local: ( cd /usr/pkgsrc/security/ssh ; make bulk-install ) if [ -f /usr/pkg/etc/rc.d/sshd ]; then /usr/pkg/etc/rc.d/sshd fi Not doing so will result in you being not able to log in via ssh after the bulk build is finished or if the machine gets rebooted or crashes. You have been warned! :) 6.3.3. Operation Make sure you don't need any of the packages still installed. Warning During the bulk build, all packages will be removed! Be sure to remove all other things that might interfere with builds, like some libs installed in /usr/local, etc. then become root and type: # cd /usr/pkgsrc # sh mk/bulk/build If for some reason your last build didn't complete (power failure, system panic, ...), you can continue it by running: # sh mk/bulk/build restart At the end of the bulk build, you will get a summary via mail, and find build logs in the directory specified by FTP in the build.conf file. 6.3.4. What it does The bulk builds consist of three steps: 1. pre-build The script updates your pkgsrc tree via (anon)cvs, then cleans out any broken distfiles, and removes all packages installed. 2. the bulk build This is basically "make bulk-package" with an optimised order in which packages will be built. Packages that don't require other packages will be built first, and packages with many dependencies will be built later. 3. post-build Generates a report that's placed in the directory specified in the build.conf file named broken.html, a short version of that report will also be mailed to the build's admin. During the build, a list of broken packages will be compiled in /usr/pkgsrc /.broken (or .../.broken.${MACHINE} if OBJMACHINE is set), individual build logs of broken builds can be found in the package's directory. These files are used by the bulk-targets to mark broken builds to not waste time trying to rebuild them, and they can be used to debug these broken package builds later. 6.3.5. Disk space requirements Currently, roughly the following requirements are valid for NetBSD 2.0/i386: * 10 GB - distfiles (NFS ok) * 8 GB - full set of all binaries (NFS ok) * 5 GB - temp space for compiling (local disk recommended) Note that all pkgs will be de-installed as soon as they are turned into a binary package, and that sources are removed, so there is no excessively huge demand to disk space. Afterwards, if the package is needed again, it will be installed via pkg_add(1) instead of building again, so there are no cycles wasted by recompiling. 6.3.6. Setting up a sandbox for chroot'ed builds If you don't want all the packages nuked from a machine (rendering it useless for anything but pkg compiling), there is the possibility of doing the package bulk build inside a chroot environment. The first step is to set up a chroot sandbox, e.g. /usr/sandbox. This can be done by using null mounts, or manually. There is a shell script called pkgsrc/mk/bulk/mksandbox which will set up the sandbox environment using null mounts. It will also create a script called sandbox in the root of the sandbox environment, which will allow the null mounts to be activated using the sandbox mount command and deactivated using the sandbox umount command. To set up a sandbox environment by hand, after extracting all the sets from a NetBSD installation or doing a make distribution DESTDIR=/usr/sandbox in /usr/ src/etc, be sure the following items are present and properly configured: 1. Kernel # cp /netbsd /usr/sandbox 2. /dev/* # cd /usr/sandbox/dev ; sh MAKEDEV all 3. /etc/resolv.conf (for security/smtpd and mail): # cp /etc/resolv.conf /usr/sandbox/etc 4. Working(!) mail config (hostname, sendmail.cf): # cp /etc/mail/sendmail.cf /usr/sandbox/etc/mail 5. /etc/localtime (for security/smtpd): # ln -sf /usr/share/zoneinfo/UTC /usr/sandbox/etc/localtime 6. /usr/src (system sources, for sysutils/aperture, net/ppp-mppe): # ln -s ../disk1/cvs . # ln -s cvs/src-2.0 src 7. Create /var/db/pkg (not part of default install): # mkdir /usr/sandbox/var/db/pkg 8. Create /usr/pkg (not part of default install): # mkdir /usr/sandbox/usr/pkg 9. Checkout pkgsrc via cvs into /usr/sandbox/usr/pkgsrc: # cd /usr/sandbox/usr # cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -d -P pkgsrc Do not mount/link this to the copy of your pkgsrc tree you do development in, as this will likely cause problems! 10. Make /usr/sandbox/usr/pkgsrc/packages and .../distfiles point somewhere appropriate. NFS- and/or nullfs-mounts may come in handy! 11. Edit /etc/mk.conf, see Section 6.3.1.1, "/etc/mk.conf". 12. Adjust mk/bulk/build.conf to suit your needs. 13. If you have set CVS_USER in build.conf, make sure that account exists and can do a cvs ${CVS_FLAGS} update properly! When the chroot sandbox is setup, you can start the build with the following steps: # cd /usr/sandbox/usr/pkgsrc # sh mk/bulk/do-sandbox-build This will just jump inside the sandbox and start building. At the end of the build, mail will be sent with the results of the build. Created binary pkgs will be in /usr/sandbox/usr/pkgsrc/packages (wherever that points/mounts to/ from). 6.3.7. Building a partial set of packages In addition to building a complete set of all packages in pkgsrc, the pkgsrc/mk /bulk/build script may be used to build a subset of the packages contained in pkgsrc. By setting defining SPECIFIC_PKGS in /etc/mk.conf, the variables * SITE_SPECIFIC_PKGS * HOST_SPECIFIC_PKGS * GROUP_SPECIFIC_PKGS * USER_SPECIFIC_PKGS will define the set of packages which should be built. The bulk build code will also include any packages which are needed as dependencies for the explicitly listed packages. One use of this is to do a bulk build with SPECIFIC_PKGS in a chroot sandbox periodically to have a complete set of the binary packages needed for your site available without the overhead of building extra packages that are not needed. 6.3.8. Uploading results of a bulk build This section describes how pkgsrc developers can upload binary pkgs built by bulk builds to ftp.NetBSD.org. If you would like to automatically create checksum files for the binary packages you intend to upload, remember to set MKSUMS=yes in your mk/bulk/ build.conf. If you would like to PGP sign the checksum files (highly recommended!), remember to set SIGN_AS=username@NetBSD.org in your mk/bulk/build.conf. This will prompt you for your GPG password to sign the files before uploading everything. Then, make sure that you have RSYNC_DST set properly in your mk/bulk/build.conf file, i.e. adjust it to something like one of the following: RSYNC_DST=$CVS_USER@ftp.NetBSD.org:/pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch/upload Please use appropviate values for "pkgsrc-200xQy", "NetBSD-a.b.c" and "arch" here. If your login on ftp.NetBSD.org is different from CVS_USER, write your login directly into the variable, e.g. my local account is "feyrer", but for my login "hubertf", I use: RSYNC_DST=hubertf@ftp.NetBSD.org:/pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch/upload A separate upload directory is used here to allow "closing" the directory during upload. To do so, run the following command on ftp.NetBSD.org next: nbftp% mkdir -p -m 750 /pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch/upload Please note that /pub/NetBSD/packages is only appropriate for packages for the NetBSD operating system. Binary packages for other operating systems should go into /pub/pkgsrc. Before uploading the binary pkgs, ssh authentication needs to be set up. This example shows how to setup temporary keys for the root account inside the sandbox (assuming that no keys should be present there usually): # chroot /usr/sandbox chroot-# rm $HOME/.ssh/id-dsa* chroot-# ssh-keygen -t dsa chroot-# cat $HOME/.ssh/id-dsa.pub Now take the output of id-dsa.pub and append it to your ~/.ssh/authorized_keys file on ftp.NetBSD.org. You can remove the key after the upload is done! Next, test if your ssh connection really works: chroot-# ssh ftp.NetBSD.org date Use "-l yourNetBSDlogin" here as appropriate! Now after all this works, you can exit the sandbox and start the upload: chroot-# exit # cd /usr/sandbox/usr/pkgsrc # sh mk/bulk/do-sandbox-upload The upload process may take quite some time. Use ls(1) or du(1) on the FTP server to monitor progress of the upload. The upload script will take care of not uploading restricted packages and putting vulnerable packages into the vulnerable subdirectory. After the upload has ended, first thing is to revoke ssh access: nbftp% vi ~/.ssh/authorized_keys Gdd:x! Use whatever is needed to remove the key you've entered before! Last, move the uploaded packages out of the upload directory to have them accessible to everyone: nbftp% cd /pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch nbftp% mv upload/* . nbftp% rmdir upload nbftp% chmod 755 . 6.4. Creating a multiple CD-ROM packages collection After your pkgsrc bulk-build has completed, you may wish to create a CD-ROM set of the resulting binary packages to assist in installing packages on other machines. The pkgtools/cdpack package provides a simple tool for creating the ISO 9660 images. cdpack arranges the packages on the CD-ROMs in a way that keeps all the dependencies for given package on the same CD as that package. 6.4.1. Example of cdpack Complete documentation for cdpack is found in the cdpack(1) manpage. The following short example assumes that the binary packages are left in /usr/ pkgsrc/packages/All and that sufficient disk space exists in /u2 to hold the ISO 9660 images. # mkdir /u2/images # pkg_add /usr/pkgsrc/packages/All/cdpack # cdpack /usr/pkgsrc/packages/All /u2/images If you wish to include a common set of files (COPYRIGHT, README, etc.) on each CD in the collection, then you need to create a directory which contains these files. e.g. # mkdir /tmp/common # echo "This is a README" > /tmp/common/README # echo "Another file" > /tmp/common/COPYING # mkdir /tmp/common/bin # echo "#!/bin/sh" > /tmp/common/bin/myscript # echo "echo Hello world" >> /tmp/common/bin/myscript # chmod 755 /tmp/common/bin/myscript Now create the images: # cdpack -x /tmp/common /usr/pkgsrc/packages/All /u2/images Each image will contain README, COPYING, and bin/myscript in their root directories.

Where's the pkgviews documentation? Pkgviews is tightly integrated with buildlink. You can find a pkgviews User's guide in pkgsrc/mk/buildlink3/PKGVIEWS_UG. 7.3. Utilities for package management (pkgtools) The pkgsrc/pkgtools directory pkgtools contains a number of useful utilities for both users and developers of pkgsrc. This section attempts only to make the reader aware of the utilities and when they might be useful, and not to duplicate the documentation that comes with each package. Utilities used by pkgsrc (automatically installed when needed): * pkgtools/x11-links: Symlinks for use by buildlink. OS tool augmentation (automatically installed when needed): * pkgtools/digest: Calculates various kinds of checksums (including SHA1). * pkgtools/libnbcompat: Compatibility library for pkgsrc tools. * pkgtools/mtree: Installed on non-BSD systems due to lack of native mtree. * pkgtools/pkg_install: Up-to-date replacement for /usr/sbin/pkg_install, or for use on operating systems where pkg_install is not present. Utilities used by pkgsrc (not automatically installed): * pkgtools/pkg_tarup: Create a binary package from an already-installed package. Used by make replace to save the old package. * pkgtools/dfdisk: Adds extra functionality to pkgsrc, allowing it to fetch distfiles from multiple locations. It currently supports the following methods: multiple CD-ROMs and network FTP/HTTP connections. * pkgtools/xpkgwedge: Put X11 packages someplace else (enabled by default). * devel/cpuflags: Determine the best compiler flags to optimise code for your current CPU and compiler. Utilities for keeping track of installed packages, being up to date, etc: * pkgtools/pkg_chk: Reports on packages whose installed versions do not match the latest pkgsrc entries. * pkgtools/pkgdep: Makes dependency graphs of packages, to aid in choosing a strategy for updating. * pkgtools/pkgdepgraph: Makes graphs from the output of pkgtools/pkgdep (uses graphviz). * pkgtools/pkglint: The pkglint(1) program checks a pkgsrc entry for errors, lintpkgsrc(1) does various checks on the complete pkgsrc system. * pkgtools/pkgsurvey: Report what packages you have installed. Utilities for people maintaining or creating individual packages: * pkgtools/pkgdiff: Automate making and maintaining patches for a package (includes pkgdiff, pkgvi, mkpatches, etc.). * pkgtools/rpm2pkg, pkgtools/url2pkg: Aids in converting to pkgsrc. * pkgtools/gensolpkg: Convert pkgsrc to a Solaris package. Utilities for people maintaining pkgsrc (or more obscure pkg utilities) * pkgtools/pkgconflict: Find packages that conflict but aren't marked as such. * pkgtools/pkg_comp: Build packages in a chrooted area. * pkgtools/libkver: Spoof kernel version for chrooted cross builds. 7.4. How to use pkgsrc as non-root If you want to use pkgsrc as non-root user, you can set some variables to make pkgsrc work under these conditions. At the very least, you need to set UNPRIVILEGED to "yes"; this will turn on unprivileged mode and set multiple related variables to allow installation of packages as non-root. In case the defaults are not enough, you may want to tune some other variables used. For example, if the automatic user/group detection leads to incorrect values (or not the ones you would like to use), you can change them by setting UNPRIVILEGED_USER and UNPRIVILEGED_GROUP respectively. As regards bootstrapping, please note that the bootstrap script will ease non-root configuration when given the "--ignore-user-check" flag, as it will choose and use multiple default directories under ~/pkg as the installation targets. These directories can be overriden by the "--prefix" flag provided by the script, as well as some others that allow finer tuning of the tree layout. 7.5. How to resume transfers when fetching distfiles? By default resuming transfers in pkgsrc is disabled, but you can enable this feature by adding the option PKG_RESUME_TRANSFERS=YES into /etc/mk.conf. If, during a fetch step, an incomplete distfile is found, pkgsrc will try to resume it. You can also use a different program than the default ftp(1) by changing the FETCH_CMD variable. Don't forget to set FETCH_RESUME_ARGS and FETCH_OUTPUT_ARGS if you are not using default values. For example, if you want to use wget to resume downloads, you'll have to use something like: FETCH_CMD=wget FETCH_BEFORE_ARGS=--passive-ftp FETCH_RESUME_ARGS=-c FETCH_OUTPUT_ARGS=-O 7.6. How can I install/use XFree86 from pkgsrc? If you want to use XFree86 from pkgsrc instead of your system's own X11 (/usr/ X11R6, /usr/openwin, ...), you will have to add the following line into /etc/ mk.conf: X11_TYPE=XFree86 7.7. How can I install/use X.org from pkgsrc? If you want to use X.org from pkgsrc instead of your system's own X11 (/usr/ X11R6, /usr/openwin, ...) you will have to add the following line into /etc/ mk.conf: X11_TYPE=xorg 7.8. How to fetch files from behind a firewall If you are sitting behind a firewall which does not allow direct connections to Internet hosts (i.e. non-NAT), you may specify the relevant proxy hosts. This is done using an environment variable in the form of a URL e.g. in Amdahl, the machine "orpheus.amdahl.com" is one of the firewalls, and it uses port 80 as the proxy port number. So the proxy environment variables are: ftp_proxy=ftp://orpheus.amdahl.com:80/ http_proxy=http://orpheus.amdahl.com:80/ 7.9. How do I tell make fetch to do passive FTP? This depends on which utility is used to retrieve distfiles. From bsd.pkg.mk, FETCH_CMD is assigned the first available command from the following list: * ${LOCALBASE}/bin/ftp * /usr/bin/ftp On a default NetBSD installation, this will be /usr/bin/ftp, which automatically tries passive connections first, and falls back to active connections if the server refuses to do passive. For the other tools, add the following to your /etc/mk.conf file: PASSIVE_FETCH=1. Having that option present will prevent /usr/bin/ftp from falling back to active transfers. 7.10. How to fetch all distfiles at once You would like to download all the distfiles in a single batch from work or university, where you can't run a make fetch. There is an archive of distfiles on ftp.NetBSD.org, but downloading the entire directory may not be appropriate. The answer here is to do a make fetch-list in /usr/pkgsrc or one of it's subdirectories, carry the resulting list to your machine at work/school and use it there. If you don't have a NetBSD-compatible ftp(1) (like lukemftp) at work, don't forget to set FETCH_CMD to something that fetches a URL: At home: % cd /usr/pkgsrc % make fetch-list FETCH_CMD=wget DISTDIR=/tmp/distfiles >/tmp/fetch.sh % scp /tmp/fetch.sh work:/tmp At work: % sh /tmp/fetch.sh then tar up /tmp/distfiles and take it home. If you have a machine running NetBSD, and you want to get all distfiles (even ones that aren't for your machine architecture), you can do so by using the above-mentioned make fetch-list approach, or fetch the distfiles directly by running: % make mirror-distfiles If you even decide to ignore NO_{SRC,BIN}_ON_{FTP,CDROM}, then you can get everything by running: % make fetch NO_SKIP=yes 7.11. What does "Don't know how to make /usr/share/tmac/tmac.andoc" mean? When compiling the pkgtools/pkg_install package, you get the error from make that it doesn't know how to make /usr/share/tmac/tmac.andoc? This indicates that you don't have installed the "text" set (nroff, ...) from the NetBSD base distribution on your machine. It is recommended to do that to format manpages. In the case of the pkgtools/pkg_install package, you can get away with setting NOMAN=YES either in the environment or in /etc/mk.conf. 7.12. What does "Could not find bsd.own.mk" mean? You didn't install the compiler set, comp.tgz, when you installed your NetBSD machine. Please get it and install it, by extracting it in /: # cd / # tar --unlink -zxvpf .../comp.tgz comp.tgz is part of every NetBSD release. Get the one that corresponds to your release (determine via uname -r). 7.13. Using 'sudo' with pkgsrc When installing packages as non-root user and using the just-in-time su(1) feature of pkgsrc, it can become annoying to type in the root password for each required package installed. To avoid this, the sudo package can be used, which does password caching over a limited time. To use it, install sudo (either as binary package or from security/sudo) and then put the following into your /etc /mk.conf: .if exists(${LOCALBASE}/bin/sudo) SU_CMD=${LOCALBASE}/bin/sudo /bin/sh -c .endif 7.14. How do I change the location of configuration files? As the system administrator, you can choose where configuration files are installed. The default settings make all these files go into ${PREFIX}/etc or some of its subdirectories; this may be suboptimal depending on your expectations (e.g., a read-only, NFS-exported PREFIX with a need of per-machine configuration of the provided packages). In order to change the defaults, you can modify the PKG_SYSCONFBASE variable (in /etc/mk.conf) to point to your preferred configuration directory; some common examples include /etc or /etc/pkg. Furthermore, you can change this value on a per-package basis by setting the PKG_SYSCONFDIR.${PKG_SYSCONFVAR} variable. PKG_SYSCONFVAR's value usually matches the name of the package you would like to modify, that is, the contents of PKGBASE. Note that, after changing these settings, you must rebuild and reinstall any affected packages. 7.15. Automated security checks Please be aware that there can often be bugs in third-party software, and some of these bugs can leave a machine vulnerable to exploitation by attackers. In an effort to lessen the exposure, the NetBSD packages team maintains a database of known-exploits to packages which have at one time been included in pkgsrc. The database can be downloaded automatically, and a security audit of all packages installed on a system can take place. To do this, install the security /audit-packages package. It has two components: 1. download-vulnerability-list, an easy way to download a list of the security vulnerabilities information. This list is kept up to date by the NetBSD security officer and the NetBSD packages team, and is distributed from the NetBSD ftp server: ftp://ftp.NetBSD.org/pub/NetBSD/packages/distfiles/pkg-vulnerabilities 2. audit-packages, an easy way to audit the current machine, checking each vulnerability which is known. If a vulnerable package is installed, it will be shown by output to stdout, including a description of the type of vulnerability, and a URL containing more information. Use of the security/audit-packages package is strongly recommended! After "audit-packages" is installed, please read the package's message, which you can get by running pkg_info -D audit-package.

Package components - files, directories and contents Table of Contents 8.1. Makefile 8.2. distinfo 8.3. patches/* 8.4. Other mandatory files 8.5. Optional files 8.6. work* 8.7. files/* Whenever you're preparing a package, there are a number of files involved which are described in the following sections. 8.1. Makefile Building, installation and creation of a binary package are all controlled by the package's Makefile. The Makefile describes various things about a package, for example from where to get it, how to configure, build, and install it. A package Makefile contains several sections that describe the package. In the first section there are the following variables, which should appear exactly in the order given here. * DISTNAME is the basename of the distribution file to be downloaded from the package's website. * PKGNAME is the name of the package, as used by pkgsrc. You only need to provide it if it differs from DISTNAME. Usually it is the directory name together with the version number. It must match the regular expression ^ [A-Za-z0-9][A-Za-z0-9-_.+]*$, that is, it starts with a letter or digit, and contains only letters, digits, dashes, underscores, dots and plus signs. * CATEGORIES is a list of categories which the package fits in. You can choose any of the top-level directories of pkgsrc for it. * MASTER_SITES is a list of URLs where the distribution files can be downloaded. Each URL must end with a slash. The second section contains the following variables. * MAINTAINER is the mail address of the package's maintainer, which is the person you can contact when the package does not work. * HOMEPAGE is a URL where users can find more information about the package. * COMMENT is a one-line comment about the purpose of the package. The MASTER_SITES may be set to one of the predefined sites: ${MASTER_SITE_APACHE} ${MASTER_SITE_BACKUP} ${MASTER_SITE_CYGWIN} ${MASTER_SITE_DEBIAN} ${MASTER_SITE_FREEBSD} ${MASTER_SITE_FREEBSD_LOCAL} ${MASTER_SITE_GNOME} ${MASTER_SITE_GNU} ${MASTER_SITE_GNUSTEP} ${MASTER_SITE_IFARCHIVE} ${MASTER_SITE_MOZILLA} ${MASTER_SITE_OPENOFFICE} ${MASTER_SITE_PERL_CPAN} ${MASTER_SITE_R_CRAN} ${MASTER_SITE_SOURCEFORGE} ${MASTER_SITE_SUNSITE} ${MASTER_SITE_SUSE} ${MASTER_SITE_TEX_CTAN} ${MASTER_SITE_XCONTRIB} ${MASTER_SITE_XEMACS} If one of these predefined sites is chosen, you may require the ability to specify a subdirectory of that site. Since these macros may expand to more than one actual site, you must use the following construct to specify a subdirectory: ${MASTER_SITE_GNU:=subdirectory/name/} ${MASTER_SITE_SOURCEFORGE:=project_name/} Note the trailing slash after the subdirectory name. Note MASTER_SITE_SUBDIR has been deprecated and should no longer be used. If the package has multiple DISTFILES or multiple PATCHFILES from different sites, set SITES_foo to a list of URI's where file "foo" may be found. "foo" includes the suffix, e.g. DISTFILES= ${DISTNAME}${EXTRACT_SUFX} DISTFILES+= foo-file.tar.gz SITES_foo-file.tar.gz=http://www.somewhere.com/somehow/ \ http://www.somewhereelse.com/mirror/somehow/ Note that the normal default setting of DISTFILES must be made explicit if you want to add to it (rather than replace it), as you usually would. Currently the following values are available for CATEGORIES. If more than one is used, they need to be separated by spaces: archivers cross geography meta-pkgs security audio databases graphics misc shells benchmarks devel ham multimedia sysutils biology editors inputmethod net textproc cad emulators lang news time chat finance mail parallel wm comms fonts math pkgtools www converters games mbone print x11 Please pay attention to the following gotchas: * Add MANCOMPRESSED if manpages are installed in compressed form by the package; see comment in bsd.pkg.mk. * Replace /usr/local with "${PREFIX}" in all files (see patches, below). * If the package installs any info files, see Section 15.5.7, "Packages installing info files". * Set MAINTAINER to be yourself. If you really can't maintain the package for future updates, set it to . * If a home page for the software in question exists, add the variable HOMEPAGE right after MAINTAINER. The value of this variable should be the URL for the home page. * Be sure to set the COMMENT variable to a short description of the package, not containing the pkg's name. 8.2. distinfo Most important, the mandatory message digest, or checksum, of all the distfiles needed for the package to compile, confirming they match the original file distributed by the author. This ensures that the distfile retrieved from the Internet has not been corrupted during transfer or altered by a malign force to introduce a security hole. It is generated using the make makesum command. The digest algorithm used was, at one stage, md5, but that was felt lacking compared to sha1, and so sha1 is now the default algorithm. The distfile size is also generated and stored in new distinfo files. The pkgtools/digest utility calculates all of the digests in the distinfo file, and it provides various different algorithms. At the current time, the algorithms provided are: md5, rmd160, sha1, sha256, sha384 and sha512. Some packages have different sets of distfiles on a per architecture basis, for example www/navigator). These are kept in the same distinfo file and care should be taken when upgrading such a package to ensure distfile information is not lost. The message digest/checksum for all the official patches found in the patches/ directory (see Section 8.3, "patches/*") for the package is also stored in the distinfo file. This is a message digest/checksum of all lines in the patch file except the NetBSD RCS Id. This file is generated by invoking make makepatchsum (or make mps if you're in a hurry). 8.3. patches/* This directory contains files that are used by the patch(1) command to modify the sources as distributed in the distribution file into a form that will compile and run perfectly on NetBSD. The files are applied successively in alphabetic order (as returned by a shell "patches/patch-*" glob expansion), so patch-aa is applied before patch-ab, etc. The patch-* files should be in diff -bu format, and apply without a fuzz to avoid problems. (To force patches to apply with fuzz you can set PATCH_FUZZ_FACTOR=-F2). Furthermore, do not put changes for more than one file into a single patch-file, as this will make future modifications more difficult. Similar, a file should be patched at most once, not several times by several different patches. If a file needs several patches, they should be combined into one file. One important thing to mention is to pay attention that no RCS IDs get stored in the patch files, as these will cause problems when later checked into the NetBSD CVS tree. Use the pkgdiff from the pkgtools/pkgdiff package to avoid these problems. For even more automation, we recommend using mkpatches from the same package to make a whole set of patches. You just have to backup files before you edit them to filename.orig, e.g. with cp -p filename filename.orig or, easier, by using pkgvi again from the same package. If you upgrade a package this way, you can easily compare the new set of patches with the previously existing one with patchdiff. When you have finished a package, remember to generate the checksums for the patch files by using the make makepatchsum command, see Section 8.2, "distinfo" . Patch files that are distributed by the author or other maintainers can be listed in $PATCHFILES. If it is desired to store any patches that should not be committed into pkgsrc, they can be kept outside the pkgsrc tree in the $LOCALPATCHES directory. The directory tree there is expected to have the same "category/package" structure as pkgsrc, and patches are expected to be stored inside these dirs (also known as $LOCALPATCHES/$PKGPATH). For example if you want to keep a private patch for pkgsrc/graphics/png, keep it in $LOCALPATCHES/graphics/png/mypatch. All files in the named directory are expected to be patch files, and they are applied after pkgsrc patches are applied. 8.4. Other mandatory files DESCR A multi-line description of the piece of software. This should include any credits where they are due. Please bear in mind that others do not share your sense of humour (or spelling idiosyncrasies), and that others will read everything that you write here. PLIST This file governs the files that are installed on your system: all the binaries, manual pages, etc. There are other directives which may be entered in this file, to control the creation and deletion of directories, and the location of inserted files. See Chapter 10, PLIST issues for more information. 8.5. Optional files INSTALL This shell script is invoked twice by pkg_add(1). First time after package extraction and before files are moved in place, the second time after the files to install are moved in place. This can be used to do any custom procedures not possible with @exec commands in PLIST. See pkg_add(1) and pkg_create(1) for more information. DEINSTALL This script is executed before and after any files are removed. It is this script's responsibility to clean up any additional messy details around the package's installation, since all pkg_delete knows is how to delete the files created in the original distribution. See pkg_delete(1) and pkg_create(1) for more information. MESSAGE Display this file after installation of the package. Useful for things like legal notices on almost-free software and hints for updating config files after installing modules for apache, PHP etc. Please note that you can modify variables in it easily by using MESSAGE_SUBST in the package's Makefile: MESSAGE_SUBST+= SOMEVAR="somevalue" replaces "${SOMEVAR}" with "somevalue" in MESSAGE. 8.6. work* When you type make the distribution files are unpacked into this directory. It can be removed by running make clean. Besides the sources, this directory is also used to keep various timestamp files. If a package doesn't create a subdirectory for itself (like GNU software does, for instance), but extracts itself in the current directory, you should set WRKSRC accordingly, e.g. editors/sam again, but the quick answer is: WRKSRC= ${WRKDIR} Please note that the old NO_WRKSUBDIR has been deprecated and should not be used. Also, if your package doesn't create a subdir with the name of DISTNAME but some different name, set WRKSRC to point to the proper name in ${WRKDIR}. See lang/tcl and x11/tk for examples, and here is another one: WRKSRC= ${WRKDIR}/${DISTNAME}/unix The name of the working directory created by pkgsrc is work by default. If the same pkgsrc tree should be used on several different platforms, the variable OBJMACHINE can be set in /etc/mk.conf to attach the platform to the directory name, e.g. work.i386 or work.sparc. 8.7. files/* If you have any files that you wish to be placed in the package prior to configuration or building, you could place these files here and use a "${CP}" command in the "pre-configure" target to achieve this. Alternatively, you could simply diff the file against /dev/null and use the patch mechanism to manage the creation of this file. Chapter 9. Programming in Makefiles Table of Contents 9.1.

Passing variables to a shell command 9.2.4. Quoting guideline 9.2.5. Workaround for a bug in BSD Make Pkgsrc consists of many Makefile fragments, each of which forms a well-defined part of the pkgsrc system. Using the make(1) system as a programming language for a big system like pkgsrc requires some discipline to keep the code correct and understandable. The basic ingredients for Makefile programming are variables (which are actually macros) and shell commands. Among these shell commands may even be more complex ones like awk(1) programs. To make sure that every shell command runs as intended it is necessary to quote all variables correctly when they are used. This chapter describes some patterns, that appear quite often in Makefiles, including the pitfalls that come along with them. 9.1. Makefile variables Makefile variables contain strings that can be processed using the five operators ``='', ``+='', ``?='', ``:='', and ``!='', which are described in the make(1) man page. When a variable's value is parsed from a Makefile, the hash character ``#'' and the backslash character ``\'' are handled specially. If a backslash is followed by a newline, any whitespace immediately in front of the backslash, the backslash, the newline, and any whitespace immediately behind the newline are replaced with a single space. A backspace character and an immediately following hash character are replaced with a single hash character. Otherwise the backslash is passed as is. In a variable assignment, any hash character that is not preceded by a backslash starts a comment that continues upto the end of the logical line. Note: Because of this parsing algorithm the only way to create a variable consisting of a single backslash is using the ``!='' operator, for example: BACKSLASH!=echo "\\". So far for defining variables. The other thing you can do with variables is evaluating them. A variable is evaluated when it is part of the right side of the ``:='' or the ``!='' operator, or directly before executing a shell command which the variable is part of. In all other cases make(1) performs lazy evaluation, that is, variables are not evaluated until there's no other way. The ``modifiers'' mentioned in the man page also evaluate the variable. Some of the modifiers split the string into words and then operate on the words, others operate on the string as a whole. When a string is splitted into words, it is splitted as you would expect it from sh(1). No rule without exception?the .for loop does not follow the shell quoting rules but splits at sequences of whitespace. There are several types of variables that should be handled differently. Strings and two types of lists. * Strings can contain arbitrary characters. Nevertheless you should restrict yourself to only using printable characters. Examples are PREFIX and COMMENT. * Internal lists are lists that are never exported to any shell command. Their elements are separated by whitespace. Therefore the elements themselves cannot have embedded whitespace. Any other characters are allowed. Internal lists can be used in .for loops. Examples are DEPENDS and BUILD_DEPENDS. * External lists are lists that may be exported to a shell command. Their elements can contain any characters, including whitespace. That's why they cannot be used in .for loops. Examples are DISTFILES and MASTER_SITES. 9.1.1. Naming conventions * All variable names starting with an underscore are reserved for use by the pkgsrc infrastructure. They shall not be used by package Makefiles. * In .for loops you should use lowercase variable names for the iteration variables. * All list variables should have a ``plural'' name, e.g. PKG_OPTIONS or DISTFILES. 9.2. Code snippets This section presents you with some code snippets you should use in your own code. If you don't find anything appropriate here, you should test your code and add it here. 9.2.1. Adding things to a list STRING= foo * bar `date` INT_LIST= # empty ANOTHER_INT_LIST= apache-[0-9]*:../../www/apache EXT_LIST= # empty ANOTHER_EXT_LIST= a=b c=d INT_LIST+= ${STRING} # 1 INT_LIST+= ${ANOTHER_INT_LIST} # 2 EXT_LIST+= ${STRING:Q} # 3 EXT_LIST+= ${ANOTHER_EXT_LIST} # 4 When you add a string to an external list (example 3), it must be quoted. In all other cases, you must not add a quoting level. You must not merge internal and external lists, unless you are sure that all entries are correctly interpreted in both lists. 9.2.2. Converting an internal list into an external list EXT_LIST= # empty .for i in ${INT_LIST} EXT_LIST+= ${i:Q}"" .endfor This code converts the internal list INT_LIST into the external list EXT_LIST. As the elements of an internal list are unquoted they must be quoted here. The reason for appending "" is explained below. 9.2.3. Passing variables to a shell command STRING= foo bar < > * `date` $$HOME ' " EXT_LIST= string=${STRING:Q} x=second\ item all: echo ${STRING} # 1 echo "${STRING}" # 2 echo "${STRING:Q}" # 3 echo ${STRING:Q} # 4 echo x${STRING:Q} | sed 1s,.,, # 5 env ${EXT_LIST} /bin/sh -c 'echo "$$string"; echo "$$x"' Example 1 leads to a syntax error in the shell, as the characters are just copied. Example 2 leads to a syntax error too, and if you leave out the last " character from ${STRING}, date(1) will be executed. The $HOME shell variable would be evaluated, too. Example 3 outputs each space character preceded by a backslash (or not), depending on the implementation of the echo(1) command. Example 4 handles correctly every string that does not start with a dash. In that case, the result depends on the implementation of the echo(1) command. As long as you can guarantee that your input does not start with a dash this form is appropriate. Example 5 handles even the case of a leading dash correctly. The EXT_LIST does not need to be quoted because the quoting has already be done when adding elements to the list. As internal lists shall not be passed to the shell, there is no example for it. 9.2.4. Quoting guideline There are many possible sources of wrongly quoted variables. This section lists some of the commonly known ones. * Whenever you use the value of a list, think about what happens to leading or trailing whitespace. If the list is a well-formed shell expression you can apply the :M* modifier to strip leading and trailing whitespace from each word. The :M operator first splits its argument according to the rules of the shell, and then creates a new list consisting of all words that match the shell glob expression *, that is: all. One class of situations where this is needed is when adding a variable like CPPFLAGS to CONFIGURE_ARGS. If the configure script invokes other configure scripts it strips the leading and trailing whitespace from the variable and then passes it to the other configure scripts. But these configure scripts expect the (child) CPPFLAGS variable to be the same as the parent CPPFLAGS. That's why we better pass the CPPFLAGS value properly trimmed. And here is how we do it: CPPFLAGS= # empty CPPFLAGS+= -Wundef -DPREFIX=\"${PREFIX:Q}\" CPPFLAGS+= ${MY_CPPFLAGS} CONFIGURE_ARGS+= CPPFLAGS=${CPPFLAGS:M*:Q} all: echo x${CPPFLAGS:Q}x # leading and trailing whitespace echo x${CONFIGURE_ARGS}x # properly trimmed * The example above contains one bug: The ${PREFIX} is a properly quoted shell expression, but there is the C compiler after it, which also expects a properly quoted string (this time in C syntax). The version above is therefore only correct if ${PREFIX} does not have embedded backslashes or double quotes. If you want to allow these, you have to add another layer of quoting to each variable that is used as a C string literal. You cannot use the :Q operator for it, as this operator only works for the shell. * Whenever a variable can be empty the :Q operator can have surprising results. Here are two completely different cases which can be solved with the same trick. EMPTY= # empty empty_test: for i in a ${EMPTY:Q} c; do \ echo "$$i"; \ done for_test: .for i in a:\ a:\test.txt echo ${i:Q} echo "foo" .endfor The first example will only print two of the three lines we might have expected. This is because ${EMPTY:Q} expands to the empty string, which the shell cannot see. The workaround is to write ${EMPTY:Q}"". This pattern can be often found as ${TEST} -z ${VAR:Q} or as ${TEST} -f ${FNAME:Q} (both of these are wrong). The second example will only print three lines instead of four. The first line looks like a:\ echo foo. This is because the backslash of the value a: \ is interpreted as a line-continuation by make(1), which makes the second line the arguments of the echo(1) command from the first line. To avoid this, write ${i:Q}"". 9.2.5. Workaround for a bug in BSD Make The pkgsrc bmake program does not handle the following assignment correctly. In case _othervar_ contains a ``-'' character, one of the closing braces is included in ${VAR} after this code executes. VAR:= ${VAR:N${_othervar_:C/-//}} For a more complex code snippet and a workaround, see the package regress/ make-quoting, testcase bug1. Chapter 10. PLIST issues Table of Contents 10.1. RCS ID 10.2.

Platform specific and differing PLISTs 10.8. Sharing directories between packages The PLIST file contains a package's "packing list", i.e. a list of files that belong to the package (relative to the ${PREFIX} directory it's been installed in) plus some additional statements - see the pkg_create(1) manpage for a full list. This chapter addresses some issues that need attention when dealing with the PLIST file (or files, see below!). 10.1. RCS ID Be sure to add a RCS ID line as the first thing in any PLIST file you write: @comment $NetBSD$ 10.2. Semi-automatic PLIST generation You can use the make print-PLIST command to output a PLIST that matches any new files since the package was extracted. See Section 14.3, "Other helpful targets" for more information on this target. 10.3. Tweaking output of make print-PLIST If you have used any of the *-dirs packages, as explained in Section 10.8, "Sharing directories between packages", you may have noticed that make print-PLIST outputs a set of @comments instead of real @dirrm lines. You can also do this for specific directories and files, so that the results of that command are very close to reality. This helps a lot during the update of packages. The PRINT_PLIST_AWK variable takes a set of AWK patterns and actions that are used to filter the output of print-PLIST. You can append any chunk of AWK scripting you like to it, but be careful with quoting. For example, to get all files inside the libdata/foo directory removed from the resulting PLIST: PRINT_PLIST_AWK+= /^libdata\/foo/ { next; } And to get all the @dirrm lines referring to a specific (shared) directory converted to @comments: PRINT_PLIST_AWK+= /^@dirrm share\/specific/ { print "@comment " $$0; next; } 10.4. Variable substitution in PLIST A number of variables are substituted automatically in PLISTs when a package is installed on a system. This includes the following variables: ${MACHINE_ARCH}, ${MACHINE_GNU_ARCH} Some packages like emacs and perl embed information about which architecture they were built on into the pathnames where they install their file. To handle this case, PLIST will be preprocessed before actually used, and the symbol "${MACHINE_ARCH}" will be replaced by what uname -p gives. The same is done if the string ${MACHINE_GNU_ARCH} is embedded in PLIST somewhere - use this on packages that have GNU autoconf created configure scripts. Legacy note There used to be a symbol "$ARCH" that was replaced by the output of uname -m, but that's no longer supported and has been removed. ${OPSYS}, ${LOWER_OPSYS}, ${OS_VERSION} Some packages want to embed the OS name and version into some paths. To do this, use these variables in the PLIST: * ${OPSYS} - output of "uname -s" * ${LOWER_OPSYS} - lowercase common name (eg. "solaris") * ${OS_VERSION} - "uname -r" ${PKGLOCALEDIR} Packages that install locale files should list them in the PLIST as "$ {PKGLOCALEDIR}/locale/de/LC_MESSAGES/..." instead of "share/locale/de/ LC_MESSAGES/...". This properly handles the fact that different operating systems expect locale files to be either in share or lib by default. For a complete list of values which are replaced by default, please look in bsd.pkg.mk (and search for PLIST_SUBST). If you want to change other variables not listed above, you can add variables and their expansions to this variable in the following way, similar to MESSAGE_SUBST (see Section 8.5, "Optional files"): PLIST_SUBST+= SOMEVAR="somevalue" This replaces all occurrences of "${SOMEVAR}" in the PLIST with "somevalue". 10.5. Manpage-compression Manpages should be installed in compressed form if MANZ is set (in bsd.own.mk), and uncompressed otherwise. To handle this in the PLIST file, the suffix ".gz" is appended/removed automatically for manpages according to MANZ and MANCOMPRESSED being set or not, see above for details. This modification of the PLIST file is done on a copy of it, not PLIST itself. 10.6. Changing PLIST source with PLIST_SRC To use one or more files as source for the PLIST used in generating the binary package, set the variable PLIST_SRC to the names of that file(s). The files are later concatenated using cat(1), and order of things is important. 10.7. Platform specific and differing PLISTs Some packages decide to install a different set of files based on the operating system being used. These differences can be automatically handled by using the following files: * PLIST.common * PLIST.${OPSYS} * PLIST.${MACHINE_ARCH} * PLIST.${OPSYS}-${MACHINE_ARCH} * PLIST.common_end 10.8. Sharing directories between packages A "shared directory" is a directory where multiple (and unrelated) packages install files. These directories are problematic because you have to add special tricks in the PLIST to conditionally remove them, or have some centralized package handle them. Within pkgsrc, you'll find both approaches. If a directory is shared by a few unrelated packages, it's often not worth to add an extra package to remove it. Therefore, one simply does: @unexec ${RMDIR} %D/path/to/shared/directory 2>/dev/null || ${TRUE} in the PLISTs of all affected packages, instead of the regular "@dirrm" line. However, if the directory is shared across many packages, two different solutions are available: 1. If the packages have a common dependency, the directory can be removed in that. For example, see textproc/scrollkeeper, which removes the shared directory share/omf. 2. If the packages using the directory are not related at all (they have no common dependencies), a *-dirs package is used. From now on, we'll discuss the second solution. To get an idea of the *-dirs packages available, issue: % cd .../pkgsrc % ls -d */*-dirs Their use from other packages is very simple. The USE_DIRS variable takes a list of package names (without the "-dirs" part) together with the required version number (always pick the latest one when writing new packages). For example, if a package installs files under share/applications, it should have the following line in it: USE_DIRS+= xdg-1.1 After regenerating the PLIST using make print-PLIST, you should get the right (commented out) lines. Note that, even if your package is using $X11BASE, it must not depend on the *-x11-dirs packages. Just specify the name without that part and pkgsrc (in particular, mk/dirs.mk) will take care of it.

Updating BUILDLINK_DEPENDS.pkg in buildlink3.mk files 11.3. Writing builtin.mk files 11.3.1. Anatomy of a builtin.mk file 11.3.2. Global preferences for native or pkgsrc software Buildlink is a framework in pkgsrc that controls what headers and libraries are seen by a package's configure and build processes. This is implemented in a two step process: 1. Symlink headers and libraries for dependencies into BUILDLINK_DIR, which by default is a subdirectory of WRKDIR. 2. Create wrapper scripts that are used in place of the normal compiler tools that translate -I${LOCALBASE}/include and -L${LOCALBASE}/lib into references to BUILDLINK_DIR. The wrapper scripts also make native compiler on some operating systems look like GCC, so that packages that expect GCC won't require modifications to build with those native compilers. This normalizes the environment in which a package is built so that the package may be built consistently despite what other software may be installed. Please note that the normal system header and library paths, e.g. /usr/include, /usr/ lib, etc., are always searched -- buildlink3 is designed to insulate the package build from non-system-supplied software. 11.1. Converting packages to use buildlink3 The process of converting packages to use the buildlink3 framework ("bl3ifying") is fairly straightforward. The things to keep in mind are: 1. Ensure that the build always calls the wrapper scripts instead of the actual toolchain. Some packages are tricky, and the only way to know for sure is the check ${WRKDIR}/.work.log to see if the wrappers are being invoked. 2. Don't override PREFIX from within the package Makefile, e.g. Java VMs, standalone shells, etc., because the code to symlink files into $ {BUILDLINK_DIR} looks for files relative to "pkg_info -qp pkgname". 3. Remember that only the buildlink3.mk files that you list in a package's Makefile are added as dependencies for that package. If a dependency on a particular package is required for its libraries and headers, then we replace: DEPENDS+= foo>=1.1.0:../../category/foo with .include "../../category/foo/buildlink3.mk" There are several buildlink3.mk files in pkgsrc/mk that handle special package issues: * bdb.buildlink3.mk chooses either the native or a pkgsrc Berkeley DB implementation based on the values of BDB_ACCEPTED and BDB_DEFAULT. * curses.buildlink3.mk If the system comes with neither Curses nor NCurses, this will take care to install the devel/ncurses package. * krb5.buildlink3.mk uses the value of KRB5_ACCEPTED to choose between adding a dependency on Heimdal or MIT-krb5 for packages that require a Kerberos 5 implementation. * motif.buildlink3.mk checks for a system-provided Motif installation or adds a dependency on x11/lesstif or x11/openmotif; * ossaudio.buildlink3.mk defines several variables that may be used by packages that use the Open Sound System (OSS) API; * pgsql.buildlink3.mk will accept either Postgres 7.3 or 7.4, whichever is found installed. See the file for more information. * pthread.buildlink3.mk uses the value of PTHREAD_OPTS and checks for native pthreads or adds a dependency on devel/pth as needed; * xaw.buildlink3.mk uses the value of XAW_TYPE to choose a particular Athena widgets library. The comments in those buildlink3.mk files provide a more complete description of how to use them properly. 11.2. Writing buildlink3.mk files A package's buildlink3.mk file is included by Makefiles to indicate the need to compile and link against header files and libraries provided by the package. A buildlink3.mk file should always provide enough information to add the correct type of dependency relationship and include any other buildlink3.mk files that it needs to find headers and libraries that it needs in turn. To generate an initial buildlink3.mk file for further editing, Rene Hexel's pkgtools/createbuildlink package is highly recommended. For most packages, the following command will generate a good starting point for buildlink3.mk files: % cd pkgsrc/category/pkgdir % createbuildlink -3 >buildlink3.mk 11.2.1. Anatomy of a buildlink3.mk file The following real-life example buildlink3.mk is taken from pkgsrc/graphics/ tiff: # $NetBSD: buildlink3.mk,v 1.7 2004/03/18 09:12:12 jlam Exp $ BUILDLINK_DEPTH:= ${BUILDLINK_DEPTH}+ TIFF_BUILDLINK3_MK:= ${TIFF_BUILDLINK3_MK}+ .if !empty(BUILDLINK_DEPTH:M+) BUILDLINK_DEPENDS+= tiff .endif BUILDLINK_PACKAGES:= ${BUILDLINK_PACKAGES:Ntiff} BUILDLINK_PACKAGES+= tiff .if !empty(TIFF_BUILDLINK3_MK:M+) BUILDLINK_DEPENDS.tiff+= tiff>=3.6.1 BUILDLINK_PKGSRCDIR.tiff?= ../../graphics/tiff .endif # TIFF_BUILDLINK3_MK .include "../../devel/zlib/buildlink3.mk" .include "../../graphics/jpeg/buildlink3.mk" BUILDLINK_DEPTH:= ${BUILDLINK_DEPTH:S/+$//} The header and footer manipulate BUILDLINK_DEPTH, which is common across all buildlink3.mk files and is used to track at what depth we are including buildlink3.mk files. The first section controls if the dependency on pkg is added. BUILDLINK_DEPENDS is the global list of packages for which dependencies are added by buildlink3. The second section advises pkgsrc that the buildlink3.mk file for pkg has been included at some point. BUILDLINK_PACKAGES is the global list of packages for which buildlink3.mk files have been included. It must always be appended to within a buildlink3.mk file. The third section is protected from multiple inclusion and controls how the dependency on pkg is added. Several important variables are set in the section: * BUILDLINK_DEPENDS.pkg is the actual dependency recorded in the installed package; this should always be set using += to ensure that we're appending to any pre-existing list of values. This variable should be set to the first version of the package that had the last change in the major number of a shared library or that had a major API change. * BUILDLINK_PKGSRCDIR.pkg is the location of the pkg pkgsrc directory; * BUILDLINK_DEPMETHOD.pkg (not shown above) controls whether we use BUILD_DEPENDS or DEPENDS to add the dependency on pkg. The build dependency is selected by setting BUILDLINK_DEPMETHOD.pkg to "build". By default, the full dependency is used. * BUILDLINK_INCDIRS.pkg and BUILDLINK_LIBDIRS. pkg (not shown above) are lists of subdirectories of ${BUILDLINK_PREFIX.pkg} to add to the header and library search paths. These default to "include" and "lib" respectively. * BUILDLINK_CPPFLAGS.pkg (not shown above) is the list of preprocessor flags to add to CPPFLAGS, which are passed on to the configure and build phases. The "-I" option should be avoided and instead be handled using BUILDLINK_INCDIRS.pkg as above. The following variables are all optionally defined within this second section (protected against multiple inclusion) and control which package files are symlinked into ${BUILDLINK_DIR} and how their names are transformed during the symlinking: * BUILDLINK_FILES.pkg (not shown above) is a shell glob pattern relative to $ {BUILDLINK_PREFIX.pkg} to be symlinked into ${BUILDLINK_DIR}, e.g. include/ *.h. * BUILDLINK_FILES_CMD.pkg (not shown above) is a shell pipeline that outputs to stdout a list of files relative to ${BUILDLINK_PREFIX.pkg}. The resulting files are to be symlinked into ${BUILDLINK_DIR}. By default, this takes the +CONTENTS of a pkg and filters it through $ {BUILDLINK_CONTENTS_FILTER.pkg}. * BUILDLINK_CONTENTS_FILTER.pkg (not shown above) is a filter command that filters +CONTENTS input into a list of files relative to $ {BUILDLINK_PREFIX.pkg} on stdout. By default for overwrite packages, BUILDLINK_CONTENTS_FILTER.pkg outputs the contents of the include and lib directories in the package +CONTENTS, and for pkgviews packages, it outputs any libtool archives in lib directories. * BUILDLINK_TRANSFORM.pkg (not shown above) is a list of sed arguments used to transform the name of the source filename into a destination filename, e.g. -e "s|/curses.h|/ncurses.h|g". The last section includes any buildlink3.mk needed for pkg's library dependencies. Including these buildlink3.mk files means that the headers and libraries for these dependencies are also symlinked into ${BUILDLINK_DIR} whenever the pkg buildlink3.mk file is included. 11.2.2. Updating BUILDLINK_DEPENDS. pkg in buildlink3.mk files There are two situations that require increasing the dependency listed in BUILDLINK_DEPENDS.pkg after a package update: 1. if the sonames (major number of the library version) of any installed shared libraries change; 2. if the API or interface to the header files change. In these cases, BUILDLINK_DEPENDS.pkg should be adjusted to require at least the new package version. In some cases, the packages that depend on this new version may need their PKGREVISIONs increased and, if they have buildlink3.mk files, their BUILDLINK_DEPENDS. pkg adjusted, too. This is needed so that binary packages made using it will require the correct package dependency and not settle for an older one which will not contain the necessary shared libraries. Please take careful consideration before adjusting BUILDLINK_DEPENDS.pkg as we don't want to cause unneeded package deletions and rebuilds. In many cases, new versions of packages work just fine with older dependencies. See Section 15.1.4, "Handling dependencies" for more information about dependencies on other packages, including the BUILDLINK_RECOMMENDED and RECOMMENDED definitions. 11.3. Writing builtin.mk files Some packages in pkgsrc install headers and libraries that coincide with headers and libraries present in the base system. Aside from a buildlink3.mk file, these packages should also include a builtin.mk file that includes the necessary checks to decide whether using the built-in software or the pkgsrc software is appropriate. The only requirements of a builtin.mk file for pkg are: 1. It should set USE_BUILTIN.pkg to either "yes" or "no" after it is included. 2. It should not override any USE_BUILTIN.pkg which is already set before the builtin.mk file is included. 3. It should be written to allow multiple inclusion. This is very important and takes careful attention to Makefile coding. 11.3.1. Anatomy of a builtin.mk file The following is the recommended template for builtin.mk files: .if !defined(IS_BUILTIN.foo) # # IS_BUILTIN.foo is set to "yes" or "no" depending on whether "foo" # genuinely exists in the system or not. # IS_BUILTIN.foo?= no # BUILTIN_PKG.foo should be set here if "foo" is built-in and its package # version can be determined. # . if !empty(IS_BUILTIN.foo:M[yY][eE][sS]) BUILTIN_PKG.foo?= foo-1.0 . endif .endif # IS_BUILTIN.foo .if !defined(USE_BUILTIN.foo) USE_BUILTIN.foo?= ${IS_BUILTIN.foo} . if defined(BUILTIN_PKG.foo) . for _depend_ in ${BUILDLINK_DEPENDS.foo} . if !empty(USE_BUILTIN.foo:M[yY][eE][sS]) USE_BUILTIN.foo!= \ if ${PKG_ADMIN} pmatch '${_depend_}' ${BUILTIN_PKG.foo}; then \ ${ECHO} "yes"; \ else \ ${ECHO} "no"; \ fi . endif . endfor . endif .endif # USE_BUILTIN.foo CHECK_BUILTIN.foo?= no .if !empty(CHECK_BUILTIN.foo:M[nN][oO]) # # Here we place code that depends on whether USE_BUILTIN.foo is set to # "yes" or "no". # .endif # CHECK_BUILTIN.foo The first section sets IS_BUILTIN.pkg depending on if pkg really exists in the base system. This should not be a base system software with similar functionality to pkg; it should only be "yes" if the actual package is included as part of the base system. This variable is only used internally within the builtin.mk file. The second section sets BUILTIN_PKG.pkg to the version of pkg in the base system if it exists (if IS_BUILTIN.pkg is "yes"). This variable is only used internally within the builtin.mk file. The third section sets USE_BUILTIN.pkg and is required in all builtin.mk files. The code in this section must make the determination whether the built-in software is adequate to satisfy the dependencies listed in BUILDLINK_DEPENDS. pkg. This is typically done by comparing BUILTIN_PKG.pkg against each of the dependencies in BUILDLINK_DEPENDS.pkg. USE_BUILTIN.pkg must be set to the correct value by the end of the builtin.mk file. Note that USE_BUILTIN.pkg may be "yes" even if IS_BUILTIN.pkg is "no" because we may make the determination that the built-in version of the software is similar enough to be used as a replacement. The last section is guarded by CHECK_BUILTIN.pkg, and includes code that uses the value of USE_BUILTIN.pkg set in the previous section. This typically includes, e.g., adding additional dependency restrictions and listing additional files to symlink into ${BUILDLINK_DIR} (via BUILDLINK_FILES.pkg). 11.3.2. Global preferences for native or pkgsrc software When building packages, it's possible to choose whether to set a global preference for using either the built-in (native) version or the pkgsrc version of software to satisfy a dependency. This is controlled by setting PREFER_PKGSRC and PREFER_NATIVE. These variables take values of either "yes", "no", or a list of packages. PREFER_PKGSRC tells pkgsrc to use the pkgsrc versions of software, while PREFER_NATIVE tells pkgsrc to use the built-in versions. Preferences are determined by the most specific instance of the package in either PREFER_PKGSRC or PREFER_NATIVE. If a package is specified in neither or in both variables, then PREFER_PKGSRC has precedence over PREFER_NATIVE. For example, to require using pkgsrc versions of software for all but the most basic bits on a NetBSD system, you can set: PREFER_PKGSRC= yes PREFER_NATIVE= getopt skey tcp_wrappers A package must have a builtin.mk file to be listed in PREFER_NATIVE, otherwise it is simply ignored in that list.

System startup scripts 12.3.1. Disabling handling of system startup scripts 12.4. System users and groups 12.5. System shells 12.5.1. Disabling handling of configuration files This chapter describes the framework known as pkginstall, whose key features are: * Generic installation and manipulation of directories and files outside the pkgsrc-handled tree, LOCALBASE. * Automatic handling of configuration files during installation, provided that packages are correctly designed. * Generation and installation of system startup scripts. * Registration of system users and groups. * Registration of system shells. The following sections inspect each of the above points in detail. Note that, in order to use any of the described functionalities, you must add the following to your package's Makefile: USE_PKGINSTALL=YES You may be thinking that many of the things described here could be easily done with simple code in the package's post-installation target (post-install). This is incorrect, as the code in them is only executed when building from source. Machines using binary packages could not benefit from it at all (as the code itself could be unavailable). Therefore, the only way to achieve any of the items described above is by means of the installation scripts, which are automatically generated by pkginstall. 12.1. Files and directories outside the installation prefix As you already know, the PLIST file holds a list of files and directories that belong to a package. The names used in it are relative to the installation prefix (${PREFIX}), which means that it cannot register files outside this directory (absolute path names are not allowed). Despite this restriction, some packages need to install files outside this location; e.g., under ${VARBASE} or ${PKG_SYSCONFDIR}. The only way to achieve this is to create such files during installation time by using the installation scripts. These scripts can run arbitrary commands, so they have the potential to create and manage files anywhere in the filesystem. Here is where pkginstall comes into play: it provides generic scripts to abstract the manipulation of such files and directories based on variables set in the package's Makefile. The rest of this section describes which these variables are. 12.1.1. Directory manipulation The following variables can be set to request the creation of directories anywhere in the filesystem: * MAKE_DIRS and OWN_DIRS contain a list of directories that should be created and should attempt to be destroyed by the installation scripts. The difference between the two is that the latter prompts the administrator to remove any directories that may be left after deinstallation (because they were not empty), while the former does not. * MAKE_DIRS_PERMS and OWN_DIRS_PERMS contain a list of tuples describing which directories should be created and should attempt to be destroyed by the installation scripts. Each tuple holds the following values, separated by spaces: the directory name, its owner, its group and its numerical mode. For example: MAKE_DIRS_PERMS+= ${VARBASE}/foo/private ${ROOT_USER} ${ROOT_GROUP} 0700 The difference between the two is exactly the same as their non-PERMS counterparts. 12.1.2. File manipulation Creating non-empty files outside the installation prefix is tricky because the PLIST forces all files to be inside it. To overcome this problem, the only solution is to extract the file in the known place (i.e., inside the installation prefix) and copy it to the appropriate location during installation (done by the installation scripts generated by pkginstall). We will call the former the master file in the following paragraphs, which describe the variables that can be used to automatically and consistently handle files outside the installation prefix: * CONF_FILES and SUPPORT_FILES are pairs of master and target files. During installation time, the master file is copied to the target one if and only if the latter does not exist. Upon deinstallation, the target file is removed provided that it was not modified by the installation. The difference between the two is that the latter prompts the administrator to remove any files that may be left after deinstallation (because they were not empty), while the former does not. * CONF_FILES_PERMS and SUPPORT_FILES_PERMS contain tuples describing master files as well as their target locations. For each of them, it also specifies their owner, their group and their numeric permissions, in this order. For example: SUPPORT_FILES_PERMS+= ${PREFIX}/share/somefile ${VARBASE}/somefile ${ROOT_USER} ${ROOT_GROUP} 0700 The difference between the two is exactly the same as their non-PERMS counterparts. 12.2. Configuration files Configuration files are special in the sense that they are installed in their own specific directory, PKG_SYSCONFDIR, and need special treatment during installation (most of which is automated by pkginstall). The main concept you must bear in mind is that files marked as configuration files are automatically copied to the right place (somewhere inside PKG_SYSCONFDIR) during installation if and only if they didn't exist before. Similarly, they will not be removed if they have local modifications. This ensures that administrators never lose any custom changes they may have made. 12.2.1. How PKG_SYSCONFDIR is set As said before, the PKG_SYSCONFDIR variable specifies where configuration files shall be installed. Its contents are set based upon the following variables: * PKG_SYSCONFBASE: The configuration's root directory. Defaults to ${PREFIX}/ etc although it may be overridden by the user to point to his preferred location (e.g., /etc, /etc/pkg, etc.). Packages must not use it directly. * PKG_SYSCONFSUBDIR: A subdirectory of PKG_SYSCONFBASE under which the configuration files for the package being built shall be installed. The definition of this variable only makes sense in the package's Makefile (i.e., it is not user customizable). As an example, consider the Apache package, www/apache2, which places its configuration files under the httpd/ subdirectory of PKG_SYSCONFBASE. This should be set in the package Makefile. * PKG_SYSCONFVAR: Specifies the name of the variable that holds this package's configuration directory (if different from PKG_SYSCONFBASE). It defaults to PKGBASE's value, and is always prefixed with PKG_SYSCONFDIR. * PKG_SYSCONFDIR.${PKG_SYSCONFVAR}: Holds the directory where the configuration files for the package identified by PKG_SYSCONFVAR's shall be placed. Based on the above variables, pkginstall determines the value of PKG_SYSCONFDIR, which is the only variable that can be used within a package to refer to its configuration directory. The algorithm used to set its value is basically the following: 1. If PKG_SYSCONFDIR.${PKG_SYSCONFVAR} is set, its value is used. 2. If the previous variable is not defined but PKG_SYSCONFSUBDIR is set in the package's Makefile, the resulting value is ${PKG_SYSCONFBASE}/$ {PKG_SYSCONFSUBDIR}. 3. Otherwise, it is set to ${PKG_SYSCONFBASE}. It is worth mentioning that ${PKG_SYSCONFDIR} is automatically added to OWN_DIRS. See Section 12.1.1, "Directory manipulation" what this means. 12.2.2. Telling the software were configuration files are Given that pkgsrc (and users!) expect configuration files to be in a known place, you need to teach each package where it shall install its files. In some cases you will have to patch the package Makefiles to achieve it. If you are lucky, though, it may be as easy as passing an extra flag to the configuration script; this is the case of GNU Autoconf generated files: CONFIGURE_ARGS+= --sysconfdir=${PKG_SYSCONFDIR} Note that this specifies where the package has to look for its configuration files, not where they will be originally installed (although the difference is never explicit, unfortunately). 12.2.3. Patching installations As said before, pkginstall automatically handles configuration files. This means that the packages themselves must not touch the contents of $ {PKG_SYSCONFDIR} directly. Bad news is that many software installation scripts will, out of the box, mess with the contents of that directory. So what is the correct procedure to fix this issue? You must teach the package (usually by manually patching it) to install any configuration files under the examples hierarchy, share/examples/${PKGBASE}/. This way, the PLIST registers them and the administrator always has the original copies available. Once the required configuration files are in place (i.e., under the examples hierarchy), the pkginstall framework can use them as master copies during the package installation to update what is in ${PKG_SYSCONFDIR}. To achieve this, the variables CONF_FILES and CONF_FILES_PERMS are used. Check out Section 12.1.2, "File manipulation" for information about their syntax and their purpose. Here is an example, taken from the mail/mutt package: EGDIR= ${PREFIX}/share/doc/mutt/samples CONF_FILES= ${EGDIR}/Muttrc ${PKG_SYSCONFDIR}/Muttrc Note that the EGDIR variable is specific to that package and has no meaning outside it. 12.2.4. Disabling handling of configuration files The automatic copying of config files can be toggled by setting the environment variable PKG_CONFIG prior to package installation. 12.3. System startup scripts System startup scripts are special files because they must be installed in a place known by the underlying OS, usually outside the installation prefix. Therefore, the same rules described in Section 12.1, "Files and directories outside the installation prefix" apply, and the same solutions can be used. However, pkginstall provides a special mechanism to handle these files. In order to provide system startup scripts, the package has to: 1. Store the script inside ${FILESDIR}, with the .sh suffix appended. Considering the print/cups package as an example, it has a cupsd.sh in its files directory. 2. Tell pkginstall to handle it, appending the name of the script, without its extension, to the RCD_SCRIPTS variable. Continuing the previous example: RCD_SCRIPTS+= cupsd Once this is done, pkginstall will do the following steps for each script in an automated fashion: 1. Process the file found in the files directory applying all the substitutions described in the FILES_SUBST variable. 2. Copy the script from the files directory to the examples hierarchy, $ {PREFIX}/share/examples/rc.d/. Note that this master file must be explicitly registered in the PLIST. 3. Add code to the installation scripts to copy the startup script from the examples hierarchy into the system-wide startup scripts directory. 12.3.1. Disabling handling of system startup scripts The automatic copying of config files can be toggled by setting the environment variable PKG_RCD_SCRIPTS prior to package installation. Note that the scripts will be always copied inside the examples hierarchy, ${PREFIX}/share/examples/ rc.d/, no matter what the value of this variable is. 12.4. System users and groups If a package needs to create special users and/or groups during installation, it can do so by using the pkginstall framework. Users can be created by adding entries to the PKG_USERS variable. Each entry has the following syntax, which mimics /etc/passwd: user:group[:[userid][:[descr][:[home][:shell]]]] Only the user and group are required; everything else is optional, but the colons must be in the right places when specifying optional bits. By default, a new user will have home directory /nonexistent, and login shell /sbin/nologin unless they are specified as part of the user element. Note that if the description contains spaces, then spaces should be double backslash-escaped, as in: foo:foogrp::The\\ Foomister Similarly, groups can be created using the PKG_GROUPS variable, whose syntax is: group[:groupid] As before, only the group name is required; the numeric identifier is optional. 12.5. System shells Packages that install system shells should register them in the shell database, /etc/shells, to make things easier to the administrator. This must be done from the installation scripts to keep binary packages working on any system. pkginstall provides an easy way to accomplish this task. When a package provides a shell interpreter, it has to set the PKG_SHELL variable to its absolute file name. This will add some hooks to the installation scripts to handle it. Consider the following example, taken from shells/zsh: USE_PKGINSTALL= YES PKG_SHELL= ${PREFIX}/bin/zsh 12.5.1. Disabling handling of configuration files The automatic registration of shell interpreters can be disabled by the administrator by setting the PKG_REGISTER_SHELLS environment variable to NO. Chapter 13. Options handling Table of Contents 13.1. Global default options 13.2. Converting packages to use bsd.options.mk Many packages have the ability to be built to support different sets of features. bsd.options.mk is a framework in pkgsrc that provides generic handling of those options that determine different ways in which the packages can be built. It's possible for the user to specify exactly which sets of options will be built into a package or to allow a set of global default options apply. 13.1. Global default options Global default options are listed in PKG_DEFAULT_OPTIONS, which is a list of the options that should be built into every package if that option is supported. This variable should be set in /etc/mk.conf. 13.2. Converting packages to use bsd.options.mk The following example shows how bsd.options.mk should be used by the hypothetical ``wibble'' package, either in the package Makefile, or in a file, e.g. options.mk, that is included by the main package Makefile. PKG_OPTIONS_VAR= PKG_OPTIONS.wibble PKG_SUPPORTED_OPTIONS= wibble-foo ldap PKG_OPTIONAL_GROUPS= database PKG_GROUP.database= mysql pgsql PKG_SUGGESTED_OPTIONS= wibble-foo PKG_OPTIONS_LEGACY_VARS+= WIBBLE_USE_OPENLDAP:ldap PKG_OPTIONS_LEGACY_OPTS+= foo:wibble-foo .include "../../mk/bsd.prefs.mk" # this package was previously named wibble2 .if defined(PKG_OPTIONS.wibble2) PKG_LEGACY_OPTIONS+= ${PKG_OPTIONS.wibble2} PKG_OPTIONS_DEPRECATED_WARNINGS+="Deprecated variable PKG_OPTIONS.wibble2 used, use "${PKG_OPTIONS_VAR:Q}" instead." .endif .include "../../mk/bsd.options.mk" # Package-specific option-handling ### ### FOO support ### .if !empty(PKG_OPTIONS:Mwibble-foo) CONFIGURE_ARGS+= --enable-foo .endif ### ### LDAP support ### .if !empty(PKG_OPTIONS:Mldap) . include "../../databases/openldap/buildlink3.mk" CONFIGURE_ARGS+= --enable-ldap=${BUILDLINK_PREFIX.openldap} .endif ### ### database support ### .if !empty(PKG_OPTIONS:Mmysql) . include "../../mk/mysql.buildlink3.mk" .endif .if !empty(PKG_OPTIONS:Mpgsql) . include "../../mk/pgsql.buildlink3.mk" .endif The first section contains the information about which build options are supported by the package, and any default options settings if needed. 1. PKG_OPTIONS_VAR is the name of the make(1) variable that the user can set to override the default options. It should be set to "PKG_OPTIONS.pkgbase". 2. PKG_SUPPORTED_OPTIONS is a list of build options supported by the package. 3. PKG_OPTIONS_OPTIONAL_GROUPS is a list of names of groups of mutually exclusive options. The options in each group are listed in PKG_OPTIONS_GROUP.groupname. The most specific setting of any option from the group takes precedence over all other options in the group. Options from the groups will be automatically added to PKG_SUPPORTED_OPTIONS. 4. PKG_OPTIONS_REQUIRED_GROUPS is like PKG_OPTIONS_OPTIONAL_GROUPS, but building the packages will fail if no option from the group is selected. 5. PKG_SUGGESTED_OPTIONS is a list of build options which are enabled by default. 6. PKG_OPTIONS_LEGACY_VARS is a list of "USE_VARIABLE: option" pairs that map legacy /etc/mk.conf variables to their option counterparts. Pairs should be added with "+=" to keep the listing of global legacy variables. A warning will be issued if the user uses a legacy variable. 7. PKG_OPTIONS_LEGACY_OPTS is a list of "old-option: new-option" pairs that map options that have been renamed to their new counterparts. Pairs should be added with "+=" to keep the listing of global legacy options. A warning will be issued if the user uses a legacy option. 8. PKG_LEGACY_OPTIONS is a list of options implied by deprecated variables used. This can be used for cases that neither PKG_OPTIONS_LEGACY_VARS nor PKG_OPTIONS_LEGACY_OPTS can handle, e. g. when PKG_OPTIONS_VAR is renamed. 9. PKG_OPTIONS_DEPRECATED_WARNINGS is a list of warnings about deprecated variables or options used, and what to use instead. A package should never modify PKG_DEFAULT_OPTIONS or the variable named in PKG_OPTIONS_VAR. These are strictly user-settable. To suggest a default set of options, use PKG_SUGGESTED_OPTIONS. PKG_OPTIONS_VAR must be defined before including bsd.options.mk. If none of PKG_SUPPORTED_OPTIONS, PKG_OPTIONS_OPTIONAL_GROUPS, and PKG_OPTIONS_REQUIRED_GROUPS are defined (as can happen with platform specific options if none of them is supported on the current platform), PKG_OPTIONS is set to the empty list and the package is otherwise treated as not using the options framework. After the inclusion of bsd.options.mk, the variable PKG_OPTIONS contains the list of selected build options, properly filtered to remove unsupported and duplicate options. The remaining sections contain the logic that is specific to each option. The correct way to check for an option is to check whether it is listed in PKG_OPTIONS: .if !empty(PKG_OPTIONS:Moption) If another package already has an option with the same meaning, use the same name. For options applicable to multiple packages (like enabling support for a library), use short option names (like the name of the library). For options specific to this package, prefix the name with pkgname-. Document the option and its meaning in mk/defaults/options.description. Chapter 14. The build process Table of Contents 14.1. Program location 14.2. Main targets 14.3. Other helpful targets The basic steps for building a program are always the same. First the program's source (distfile) must be brought to the local system and then extracted. After any patches to compile properly on NetBSD are applied, the software can be configured, then built (usually by compiling), and finally the generated binaries, etc. can be put into place on the system. These are exactly the steps performed by the NetBSD package system, which is implemented as a series of targets in a central Makefile, pkgsrc/mk/bsd.pkg.mk. 14.1. Program location Before outlining the process performed by the NetBSD package system in the next section, here's a brief discussion on where programs are installed, and which variables influence this. The automatic variable PREFIX indicates where all files of the final program shall be installed. It is usually set to LOCALBASE (/usr/pkg), or CROSSBASE for pkgs in the "cross" category. The value of PREFIX needs to be put into the various places in the program's source where paths to these files are encoded. See Section 8.3, "patches/*" and Section 15.3.1, "Shared libraries - libtool" for more details. When choosing which of these variables to use, follow the following rules: * PREFIX always points to the location where the current pkg will be installed. When referring to a pkg's own installation path, use "${PREFIX} ". * LOCALBASE is where all non-X11 pkgs are installed. If you need to construct a -I or -L argument to the compiler to find includes and libraries installed by another non-X11 pkg, use "${LOCALBASE}". * X11BASE is where the actual X11 distribution (from xsrc, etc.) is installed. When looking for standard X11 includes (not those installed by a pkg), use "${X11BASE}". * X11 based are special in that they may be installed in either X11BASE or LOCALBASE. Usually, X11 packages should be installed under LOCALBASE whenever possible. Note that you will need to include ../../mk/x11.buildlink3.mk in them to request the presence of X11 and to get the right compilation flags. Even though, there are some packages that cannot be installed under LOCALBASE: those that come with app-defaults files. These packages are special and they must be placed under X11BASE. To accomplish this, set either USE_X11BASE or USE_IMAKE in your package. Some notes: If you need to find includes or libraries installed by a pkg that has USE_IMAKE or USE_X11BASE in its pkg Makefile, you need to look in both ${X11BASE} and ${LOCALBASE}. To force installation of all X11 packages in LOCALBASE, the pkgtools/xpkgwedge package is enabled by default. * X11PREFIX should be used to refer to the installed location of an X11 package. X11PREFIX will be set to X11BASE if xpkgwedge is not installed, and to LOCALBASE if xpkgwedge is installed. * If xpkgwedge is installed, it is possible to have some packages installed in X11BASE and some in LOCALBASE. To determine the prefix of an installed package, the EVAL_PREFIX definition can be used. It takes pairs in the format "DIRNAME=", and the make(1) variable DIRNAME will be set to the prefix of the installed package , or "${X11PREFIX}" if the package is not installed. This is best illustrated by example. The following lines are taken from pkgsrc/wm/scwm/Makefile: EVAL_PREFIX+= GTKDIR=gtk+ CONFIGURE_ARGS+= --with-guile-prefix=${LOCALBASE} \ --with-gtk-prefix="${GTKDIR}" \ --enable-multibyte Specific defaults can be defined for the packages evaluated using EVAL_PREFIX, by using a definition of the form: GTKDIR_DEFAULT= ${LOCALBASE} where GTKDIR corresponds to the first definition in the EVAL_PREFIX pair. * Within ${PREFIX}, packages should install files according to hier(7), with the exception that manual pages go into ${PREFIX}/man, not ${PREFIX}/share/ man. 14.2. Main targets The main targets used during the build process defined in bsd.pkg.mk are: fetch This will check if the file(s) given in the variables DISTFILES and PATCHFILES (as defined in the package's Makefile) are present on the local system in /usr/pkgsrc/distfiles. If they are not present, an attempt will be made to fetch them using commands of the form: ${FETCH_CMD} ${FETCH_BEFORE_ARGS} ${site}${file} ${FETCH_AFTER_ARGS} where ${site} varies through several possibilities in turn: first, MASTER_SITE_OVERRIDE is tried, then the sites specified in either SITES_file if defined, else MASTER_SITES or PATCH_SITES, as applies, then finally the value of MASTER_SITE_BACKUP. The order of all except the first can be optionally sorted by the user, via setting either MASTER_SORT_AWK or MASTER_SORT_REGEX. checksum After the distfile(s) are fetched, their checksum is generated and compared with the checksums stored in the distinfo file. If the checksums don't match, the build is aborted. This is to ensure the same distfile is used for building, and that the distfile wasn't changed, e.g. by some malign force, deliberately changed distfiles on the master distribution site or network lossage. extract When the distfiles are present on the local system, they need to be extracted, as they are usually in the form of some compressed archive format, most commonly .tar.gz. If only some of the distfiles need to be uncompressed, the files to be uncompressed should be put into EXTRACT_ONLY. If the distfiles are not in .tar.gz format, they can be extracted by setting either EXTRACT_SUFX, or EXTRACT_CMD, EXTRACT_BEFORE_ARGS and EXTRACT_AFTER_ARGS. In the former case, pkgsrc knows how to extract a number of suffixes (.tar.gz, .tgz, .tar.gz2, .tbz, .tar.Z, .tar, .shar.gz, .shar.bz2, .shar.Z, .shar, .Z, .bz2 and .gz; see the definition of the various DECOMPRESS_CMD variables bsd.pkg.mk for a complete list). Here's an example on how to use the other variables for a program that comes with a compressed shell archive whose name ends in .msg.gz: EXTRACT_SUFX= .msg.gz EXTRACT_CMD= zcat EXTRACT_BEFORE_ARGS= EXTRACT_AFTER_ARGS= |sh patch After extraction, all the patches named by the PATCHFILES, those present in the patches subdirectory of the package as well as in $LOCALPATCHES/ $PKGPATH (e.g. /usr/local/patches/graphics/png) are applied. Patchfiles ending in .Z or .gz are uncompressed before they are applied, files ending in .orig or .rej are ignored. Any special options to patch(1) can be handed in PATCH_DIST_ARGS. See Section 8.3, "patches/*" for more details. By default patch(1) is given special args to make it fail if the patches apply with some lines of fuzz. Please fix (regen) the patches so that they apply cleanly. The rationale behind this is that patches that don't apply cleanly may end up being applied in the wrong place, and cause severe harm there. configure Most pieces of software need information on the header files, system calls, and library routines which are available in NetBSD. This is the process known as configuration, and is usually automated. In most cases, a script is supplied with the source, and its invocation results in generation of header files, Makefiles, etc. If the program's distfile contains its own configure script, this can be invoked by setting HAS_CONFIGURE. If the configure script is a GNU autoconf script, GNU_CONFIGURE should be specified instead. In either case, any arguments to the configure script can be specified in the CONFIGURE_ARGS variable, and the configure script's name can be set in CONFIGURE_SCRIPT if it differs from the default "configure". Here's an example from the sysutils/top package: HAS_CONFIGURE= yes CONFIGURE_SCRIPT= Configure CONFIGURE_ARGS+= netbsd13 If the program uses an Imakefile for configuration, the appropriate steps can be invoked by setting USE_IMAKE to "YES". (If you only want the package installed in $X11PREFIX but xmkmf not being run, set USE_X11BASE instead!) build Once configuration has taken place, the software will be built by invoking $MAKE_PROGRAM on $MAKEFILE with $BUILD_TARGET as the target to build. The default MAKE_PROGRAM is "gmake" if USE_TOOLS contains "gmake", "make" otherwise. MAKEFILE is set to "Makefile" by default, and BUILD_TARGET defaults to "all". Any of these variables can be set in the package's Makefile to change the default build process. install Once the build stage has completed, the final step is to install the software in public directories, so users can access the programs and files. As in the build-target, $MAKE_PROGRAM is invoked on $MAKEFILE here, but with the $INSTALL_TARGET instead, the latter defaulting to "install" (plus "install.man", if USE_IMAKE is set). If no target is specified, the default is "build". If a subsequent stage is requested, all prior stages are made: e.g. make build will also perform the equivalent of: make fetch make checksum make extract make patch make configure make build 14.3. Other helpful targets pre/post-* For any of the main targets described in the previous section, two auxiliary targets exist with "pre-" and "post-" used as a prefix for the main target's name. These targets are invoked before and after the main target is called, allowing extra configuration or installation steps be performed from a package's Makefile, for example, which a program's configure script or install target omitted. do-* Should one of the main targets do the wrong thing, and should there be no variable to fix this, you can redefine it with the do-* target. (Note that redefining the target itself instead of the do-* target is a bad idea, as the pre-* and post-* targets won't be called anymore, etc.) You will not usually need to do this. reinstall If you did a make install and you noticed some file was not installed properly, you can repeat the installation with this target, which will ignore the "already installed" flag. deinstall This target does a pkg_delete(1) in the current directory, effectively de-installing the package. The following variables can be used to tune the behaviour: PKG_VERBOSE Add a "-v" to the pkg_delete(1) command. DEINSTALLDEPENDS Remove all packages that require (depend on) the given package. This can be used to remove any packages that may have been pulled in by a given package, e.g. if make deinstall DEINSTALLDEPENDS=1 is done in pkgsrc/x11/kde, this is likely to remove whole KDE. Works by adding "-R" to the pkg_delete(1) command line. update This target causes the current package to be updated to the latest version. The package and all depending packages first get de-installed, then current versions of the corresponding packages get compiled and installed. This is similar to manually noting which packages are currently installed, then performing a series of make deinstall and make install (or whatever UPDATE_TARGET is set to) for these packages. You can use the "update" target to resume package updating in case a previous make update was interrupted for some reason. However, in this case, make sure you don't call make clean or otherwise remove the list of dependent packages in WRKDIR. Otherwise you lose the ability to automatically update the current package along with the dependent packages you have installed. Resuming an interrupted make update will only work as long as the package tree remains unchanged. If the source code for one of the packages to be updated has been changed, resuming make update will most certainly fail! The following variables can be used either on the command line or in /etc/ mk.conf to alter the behaviour of make update: UPDATE_TARGET Install target to recursively use for the updated package and the dependent packages. Defaults to DEPENDS_TARGET if set, "install" otherwise for make update. e.g. make update UPDATE_TARGET=package NOCLEAN Don't clean up after updating. Useful if you want to leave the work sources of the updated packages around for inspection or other purposes. Be sure you eventually clean up the source tree (see the "clean-update" target below) or you may run into troubles with old source code still lying around on your next make or make update. REINSTALL Deinstall each package before installing (making DEPENDS_TARGET). This may be necessary if the "clean-update" target (see below) was called after interrupting a running make update. DEPENDS_TARGET Allows you to disable recursion and hardcode the target for packages. The default is "update" for the update target, facilitating a recursive update of prerequisite packages. Only set DEPENDS_TARGET if you want to disable recursive updates. Use UPDATE_TARGET instead to just set a specific target for each package to be installed during make update (see above). clean-update Clean the source tree for all packages that would get updated if make update was called from the current directory. This target should not be used if the current package (or any of its depending packages) have already been de-installed (e.g., after calling make update) or you may lose some packages you intended to update. As a rule of thumb: only use this target before the first time you run make update and only if you have a dirty package tree (e.g., if you used NOCLEAN). If you unsure about whether your tree is clean you can either perform a make clean at the top of the tree, or use the following sequence of commands from the directory of the package you want to update (before running make update for the first time, otherwise you lose all the packages you wanted to update!): # make clean-update # make clean CLEANDEPENDS=YES # make update The following variables can be used either on the command line or in /etc/ mk.conf to alter the behaviour of make clean-update: CLEAR_DIRLIST After make clean, do not reconstruct the list of directories to update for this package. Only use this if make update successfully installed all packages you wanted to update. Normally, this is done automatically on make update, but may have been suppressed by the NOCLEAN variable (see above). info This target invokes pkg_info(1) for the current package. You can use this to check which version of a package is installed. readme This target generates a README.html file, which can be viewed using a browser such as www/mozilla or www/links. The generated files contain references to any packages which are in the PACKAGES directory on the local host. The generated files can be made to refer to URLs based on FTP_PKG_URL_HOST and FTP_PKG_URL_DIR. For example, if I wanted to generate README.html files which pointed to binary packages on the local machine, in the directory /usr/packages, set FTP_PKG_URL_HOST=file://localhost and FTP_PKG_URL_DIR=/usr/packages. The ${PACKAGES} directory and its subdirectories will be searched for all the binary packages. readme-all Use this target to create a file README-all.html which contains a list of all packages currently available in the NetBSD Packages Collection, together with the category they belong to and a short description. This file is compiled from the pkgsrc/*/README.html files, so be sure to run this after a make readme. cdrom-readme This is very much the same as the "readme" target (see above), but is to be used when generating a pkgsrc tree to be written to a CD-ROM. This target also produces README.html files, and can be made to refer to URLs based on CDROM_PKG_URL_HOST and CDROM_PKG_URL_DIR. show-distfiles This target shows which distfiles and patchfiles are needed to build the package. (DISTFILES and PATCHFILES, but not patches/*) show-downlevel This target shows nothing if the package is not installed. If a version of this package is installed, but is not the version provided in this version of pkgsrc, then a warning message is displayed. This target can be used to show which of your installed packages are downlevel, and so the old versions can be deleted, and the current ones added. show-pkgsrc-dir This target shows the directory in the pkgsrc hierarchy from which the package can be built and installed. This may not be the same directory as the one from which the package was installed. This target is intended to be used by people who may wish to upgrade many packages on a single host, and can be invoked from the top-level pkgsrc Makefile by using the "show-host-specific-pkgs" target. show-installed-depends This target shows which installed packages match the current package's DEPENDS. Useful if out of date dependencies are causing build problems. check-shlibs After a package is installed, check all its binaries and (on ELF platforms) shared libraries to see if they find the shared libs they need. Run by default if PKG_DEVELOPER is set in /etc/mk.conf. print-PLIST After a "make install" from a new or upgraded pkg, this prints out an attempt to generate a new PLIST from a find -newer work/.extract_done. An attempt is made to care for shared libs etc., but it is strongly recommended to review the result before putting it into PLIST. On upgrades, it's useful to diff the output of this command against an already existing PLIST file. If the package installs files via tar(1) or other methods that don't update file access times, be sure to add these files manually to your PLIST, as the "find -newer" command used by this target won't catch them! See Section 10.3, "Tweaking output of make print-PLIST" for more information on this target. bulk-package Used to do bulk builds. If an appropriate binary package already exists, no action is taken. If not, this target will compile, install and package it (and it's depends, if PKG_DEPENDS is set properly. See Section 6.3.1, "Configuration". After creating the binary package, the sources, the just-installed package and it's required packages are removed, preserving free disk space. Beware that this target may deinstall all packages installed on a system! bulk-install Used during bulk-installs to install required packages. If an upto-date binary package is available, it will be installed via pkg_add(1). If not, make bulk-package will be executed, but the installed binary not be removed. A binary package is considered "upto-date" to be installed via pkg_add(1) if: * None of the package's files (Makefile, ...) were modified since it was built. * None of the package's required (binary) packages were modified since it was built. Beware that this target may deinstall all packages installed on a system! Chapter 15. Notes on fixes for packages Table of Contents 15.1. General operation 15.1.1.

How to pull in variables from /etc/mk.conf The problem with package-defined variables that can be overridden via MAKECONF or /etc/mk.conf is that make(1) expands a variable as it is used, but evaluates preprocessor like statements (.if, .ifdef and .ifndef) as they are read. So, to use any variable (which may be set in /etc/mk.conf) in one of the .if* statements, the file /etc/mk.conf must be included before that .if* statement. Rather than have a number of ad-hoc ways of including /etc/mk.conf, should it exist, or MAKECONF, should it exist, include the pkgsrc/mk/bsd.prefs.mk file in the package Makefile before any preprocessor-like .if, .ifdef, or .ifndef statements: .include "../../mk/bsd.prefs.mk" .if defined(USE_MENUS) ... .endif If you wish to set the CFLAGS variable in /etc/mk.conf please make sure to use: CFLAGS+= -your -flags Using CFLAGS= (i.e. without the "+") may lead to problems with packages that need to add their own flags. Also, you may want to take a look at the devel/ cpuflags package if you're interested in optimization for the current CPU. 15.1.2. Where to install documentation Documentation should be installed into ${PREFIX}/share/doc/${PKGBASE} or $ {PREFIX}/share/doc/${PKGNAME} (the latter includes the version number of the package). 15.1.3. Restricted packages Some licenses restrict how software may be re-distributed. In order to satisfy these restrictions, the package system defines five make variables that can be set to note these restrictions: * RESTRICTED This variable should be set whenever a restriction exists (regardless of its kind). Set this variable to a string containing the reason for the restriction. * NO_BIN_ON_CDROM Binaries may not be placed on CD-ROM. Set this variable to ${RESTRICTED} whenever a binary package may not be included on a CD-ROM. * NO_BIN_ON_FTP Binaries may not be placed on an FTP server. Set this variable to $ {RESTRICTED} whenever a binary package may not not be made available on the Internet. * NO_SRC_ON_CDROM Distfiles may not be placed on CD-ROM. Set this variable to ${RESTRICTED} if re-distribution of the source code or other distfile(s) is not allowed on CD-ROMs. * NO_SRC_ON_FTP Distfiles may not be placed on FTP. Set this variable to ${RESTRICTED} if re-distribution of the source code or other distfile(s) via the Internet is not allowed. Please note that the use of NO_PACKAGE, IGNORE, NO_CDROM, or other generic make variables to denote restrictions is deprecated, because they unconditionally prevent users from generating binary packages! 15.1.4. Handling dependencies Your package may depend on some other package being present - and there are various ways of expressing this dependency. pkgsrc supports the BUILD_DEPENDS and DEPENDS definitions, as well as dependencies via buildlink3.mk, which is the preferred way to handle dependencies, and which uses the variables named above. See Chapter 11, Buildlink methodology for more information. The basic difference between the two variables is as follows: The DEPENDS definition registers that pre-requisite in the binary package so it will be pulled in when the binary package is later installed, whilst the BUILD_DEPENDS definition does not, marking a dependency that is only needed for building the package. This means that if you only need a package present whilst you are building, it should be noted as a BUILD_DEPENDS. The format for a BUILD_DEPENDS and a DEPENDS definition is: :../..// Please note that the "pre-req-package-name" may include any of the wildcard version numbers recognized by pkg_info(1). 1. If your package needs another package's binaries or libraries to build or run, and if that package has a buildlink3.mk file available, use it: .include "../../graphics/jpeg/buildlink3.mk" 2. If your package needs to use another package to build itself and there is no buildlink3.mk file available, use the BUILD_DEPENDS definition: BUILD_DEPENDS+= autoconf-2.13:../../devel/autoconf 3. If your package needs a library with which to link and again there is no buildlink3.mk file available, this is specified using the DEPENDS definition. An example of this is the print/lyx package, which uses the xpm library, version 3.4j to build: DEPENDS+= xpm-3.4j:../../graphics/xpm You can also use wildcards in package dependences: DEPENDS+= xpm-[0-9]*:../../graphics/xpm Note that such wildcard dependencies are retained when creating binary packages. The dependency is checked when installing the binary package and any package which matches the pattern will be used. Wildcard dependencies should be used with care. The "-[0-9]*" should be used instead of "-*" to avoid potentially ambiguous matches such as "tk-postgresql" matching a "tk-*" DEPENDS. Wildcards can also be used to specify that a package will only build against a certain minimum version of a pre-requisite: DEPENDS+= tiff>=3.5.4:../../graphics/tiff This means that the package will build against version 3.5.4 of the tiff library or newer. Such a dependency may be warranted if, for example, the API of the library has changed with version 3.5.4 and a package would not compile against an earlier version of tiff. Please note that such dependencies should only be updated if a package requires a newer pre-requisite, but not to denote recommendations such as security updates or ABI changes that do not prevent a package from building correctly. Such recommendations can be expressed using RECOMMENDED: RECOMMENDED+= tiff>=3.6.1:../../graphics/tiff In addition to the above DEPENDS line, this denotes that while a package will build against tiff>=3.5.4, at least version 3.6.1 is recommended. RECOMMENDED entries will be turned into dependencies unless explicitly ignored (in which case a warning will be printed). To ignore these dependency recommendations and just use the required DEPENDS, set IGNORE_RECOMMENDED=YES. This may make it easier and faster to update packages built using pkgsrc, since older compatible dependencies can continue to be used. This is useful for people who watch their rebuilds very carefully; it is not very good as a general-purpose hammer. If you use it, you need to be mindful of possible ABI changes, including those from the underlying OS. Packages that are built with recommendations ignored may not be uploaded to ftp.NetBSD.org by developers and should not be used across different systems that may have different versions of binary packages installed. For security fixes, please update the package vulnerabilities file as well as setting RECOMMENDED, see Section 15.1.8, "Handling packages with security problems" for more information. 4. If your package needs some executable to be able to run correctly and if there's no buildlink3.mk file, this is specified using the DEPENDS variable. The print/lyx package needs to be able to execute the latex binary from the teTeX package when it runs, and that is specified: DEPENDS+= teTeX-[0-9]*:../../print/teTeX The comment about wildcard dependencies from previous paragraph applies here, too. If your package needs files from another package to build, see the first part of the "do-configure" target print/ghostscript5 package (it relies on the jpeg sources being present in source form during the build): if [ ! -e ${_PKGSRCDIR}/graphics/jpeg/${WRKDIR:T}/jpeg-6b ]; then \ cd ${_PKGSRCDIR}/../../graphics/jpeg && ${MAKE} extract; \ fi If you build any other packages that way, please make sure the working files are deleted too when this package's working files are cleaned up. The easiest way to do so is by adding a pre-clean target: pre-clean: cd ${_PKGSRCDIR}/../../graphics/jpeg && ${MAKE} clean Please also note the BUILD_USES_MSGFMT and BUILD_USES_GETTEXT_M4 definitions, which are provided as convenience definitions. The former works out whether msgfmt(1) is part of the base system, and, if it isn't, installs the devel/ gettext package. The latter adds a build dependency on either an installed version of an older gettext package, or if it isn't, installs the devel/ gettext-m4 package. 15.1.5. Handling conflicts with other packages Your package may conflict with other packages a user might already have installed on his system, e.g. if your package installs the same set of files like another package in our pkgsrc tree. In this case you can set CONFLICTS to a space separated list of packages (including version string) your package conflicts with. For example x11/Xaw3d and x11/Xaw-Xpm install provide the same shared library, thus you set in pkgsrc/x11/Xaw3d/Makefile: CONFLICTS= Xaw-Xpm-[0-9]* and in pkgsrc/x11/Xaw-Xpm/Makefile: CONFLICTS= Xaw3d-[0-9]* Packages will automatically conflict with other packages with the name prefix and a different version string. "Xaw3d-1.5" e.g. will automatically conflict with the older version "Xaw3d-1.3". 15.1.6. Packages that cannot or should not be built There are several reasons why a package might be instructed to not build under certain circumstances. If the package builds and runs on most platforms, the exceptions should be noted with NOT_FOR_PLATFORM. If the package builds and runs on a small handful of platforms, set ONLY_FOR_PLATFORM instead. If the package should be skipped (for example, because it provides functionality already provided by the system), set PKG_SKIP_REASON to a descriptive message. If the package should fail because some preconditions are not met, set PKG_FAIL_REASON to a descriptive message. IGNORE is deprecated because it didn't provide enough information to determine whether the build should fail. 15.1.7. Packages which should not be deleted, once installed To ensure that a package may not be deleted, once it has been installed, the PKG_PRESERVE definition should be set in the package Makefile. This will be carried into any binary package that is made from this pkgsrc entry. A "preserved" package will not be deleted using pkg_delete(1) unless the "-f" option is used. 15.1.8. Handling packages with security problems When a vulnerability is found, this should be noted in localsrc/security/ advisories/pkg-vulnerabilities, and after the commit of that file, it should be copied to both /pub/NetBSD/packages/distfiles/pkg-vulnerabilities and /pub/ NetBSD/packages/distfiles/vulnerabilities on ftp.NetBSD.org using localsrc/ security/advisories/Makefile. In addition, if a buildlink3.mk file exists for an affected package, bumping PKGREVISION and creating a corresponding BUILDLINK_RECOMMENDED.pkg entry should be considered. See Chapter 11, Buildlink methodology for more information about writing buildlink3.mk files and BUILDLINK_* definitions. Also, if the fix should be applied to the stable pkgsrc branch, be sure to submit a pullup request! 15.1.9. How to handle compiler bugs Some source files trigger bugs in the compiler, based on combinations of compiler version and architecture and almost always relation to optimisation being enabled. Common symptoms are gcc internal errors or never finishing compiling a file. Typically a workaround involves testing the MACHINE_ARCH and compiler version, disabling optimisation for that file/MACHINE_ARCH/compiler combination, and documenting it in pkgsrc/doc/HACKS. See that file for a number of examples! 15.1.10. How to handle incrementing versions when fixing an existing package When making fixes to an existing package it can be useful to change the version number in PKGNAME. To avoid conflicting with future versions by the original author, a "nb1", "nb2", ... suffix can be used on package versions by setting PKGREVISION=1 (2, ...). The "nb" is treated like a "." by the pkg tools. e.g. DISTNAME= foo-17.42 PKGREVISION= 9 will result in a PKGNAME of "foo-17.42nb9". When a new release of the package is released, the PKGREVISION should be removed. e.g. on a new minor release of the above package, things should be like: DISTNAME= foo-17.43 15.1.11. Portability of packages One appealing feature of pkgsrc is that it runs on many different platforms. As a result, it is important to ensure, where possible, that packages in pkgsrc are portable. There are some particular details you should pay attention to while working on pkgsrc. 15.1.11.1. ${INSTALL}, ${INSTALL_DATA_DIR}, ... The BSD-compatible install supplied with some operating systems will not perform more than one operation at a time. As such, you should call "${INSTALL} ", etc. like this: ${INSTALL_DATA_DIR} ${PREFIX}/dir1 ${INSTALL_DATA_DIR} ${PREFIX}/dir2 15.2. Possible downloading issues 15.2.1. Packages whose distfiles aren't available for plain downloading If you need to download from a dynamic URL you can set DYNAMIC_MASTER_SITES and a make fetch will call files/getsite.sh with the name of each file to download as an argument, expecting it to output the URL of the directory from which to download it. graphics/ns-cult3d is an example of this usage. If the download can't be automated, because the user must submit personal information to apply for a password, or must pay for the source, or whatever, you can set _FETCH_MESSAGE to a macro which displays a message explaining the situation. _FETCH_MESSAGE must be executable shell commands, not just a message. (Generally, it executes ${ECHO}). As of this writing, the following packages use this: audio/realplayer, cad/simian, devel/ipv6socket, emulators/ vmware-module, fonts/acroread-jpnfont, sysutils/storage-manager, www/ ap-aolserver, www/openacs. Try to be consistent with them. 15.2.2. How to handle modified distfiles with the 'old' name Sometimes authors of a software package make some modifications after the software was released, and they put up a new distfile without changing the package's version number. If a package is already in pkgsrc at that time, the checksum will no longer match. The contents of the new distfile should be compared against the old one before changing anything, to make sure the distfile was really updated on purpose, and that no trojan horse or so crept in. Then, the correct way to work around this is to set DIST_SUBDIR to a unique directory name, usually based on PKGNAME_NOREV. In case this happens more often, PKGNAME can be used (thus including the nbX suffix) or a date stamp can be appended, like ${PKGNAME_NOREV}-YYYYMMDD. Do not forget regenerating the distinfo file after that, since it contains the DIST_SUBDIR path in the filenames. Furthermore, a mail to the package's authors seems appropriate telling them that changing distfiles after releases without changing the file names is not good practice. 15.3. Configuration gotchas 15.3.1. Shared libraries - libtool pkgsrc supports many different machines, with different object formats like a.out and ELF, and varying abilities to do shared library and dynamic loading at all. To accompany this, varying commands and options have to be passed to the compiler, linker, etc. to get the Right Thing, which can be pretty annoying especially if you don't have all the machines at your hand to test things. The devel/libtool pkg can help here, as it just "knows" how to build both static and dynamic libraries from a set of source files, thus being platform independent. Here's how to use libtool in a pkg in seven simple steps: 1. Add USE_LIBTOOL=yes to the package Makefile. 2. For library objects, use "${LIBTOOL} --mode=compile ${CC}" in place of "$ {CC}". You could even add it to the definition of CC, if only libraries are being built in a given Makefile. This one command will build both PIC and non-PIC library objects, so you need not have separate shared and non-shared library rules. 3. For the linking of the library, remove any "ar", "ranlib", and "ld -Bshareable" commands, and instead use: ${LIBTOOL} --mode=link ${CC} -o ${.TARGET:.a=.la} ${OBJS:.o=.lo} -rpath ${PREFIX}/lib -version-info major:minor Note that the library is changed to have a .la extension, and the objects are changed to have a .lo extension. Change OBJS as necessary. This automatically creates all of the .a, .so.major.minor, and ELF symlinks (if necessary) in the build directory. Be sure to include "-version-info", especially when major and minor are zero, as libtool will otherwise strip off the shared library version. From the libtool manual: So, libtool library versions are described by three integers: CURRENT The most recent interface number that this library implements. REVISION The implementation number of the CURRENT interface. AGE The difference between the newest and oldest interfaces that this library implements. In other words, the library implements all the interface numbers in the range from number `CURRENT - AGE' to `CURRENT'. If two libraries have identical CURRENT and AGE numbers, then the dynamic linker chooses the library with the greater REVISION number. The "-release" option will produce different results for a.out and ELF (excluding symlinks) in only one case. An ELF library of the form "libfoo-release.so.x.y" will have a symlink of "libfoo.so.x.y" on an a.out platform. This is handled automatically. The "-rpath argument" is the install directory of the library being built. In the PLIST, include only the .la file, the other files will be added automatically. 4. When linking shared object (.so) files, i.e. files that are loaded via dlopen(3), NOT shared libraries, use "-module -avoid-version" to prevent them getting version tacked on. The PLIST file gets the foo.so entry. 5. When linking programs that depend on these libraries before they are installed, preface the cc(1) or ld(1) line with "${LIBTOOL} --mode=link", and it will find the correct libraries (static or shared), but please be aware that libtool will not allow you to specify a relative path in -L (such as "-L../somelib"), because it expects you to change that argument to be the .la file. e.g. ${LIBTOOL} --mode=link ${CC} -o someprog -L../somelib -lsomelib should be changed to: ${LIBTOOL} --mode=link ${CC} -o someprog ../somelib/somelib.la and it will do the right thing with the libraries. 6. When installing libraries, preface the install(1) or cp(1) command with "$ {LIBTOOL} --mode=install", and change the library name to .la. e.g. ${LIBTOOL} --mode=install ${BSD_INSTALL_DATA} ${SOMELIB:.a=.la} ${PREFIX}/lib This will install the static .a, shared library, any needed symlinks, and run ldconfig(8). 7. In your PLIST, include only the .la file (this is a change from previous behaviour). 15.3.2. Using libtool on GNU packages that already support libtool Add USE_LIBTOOL=yes to the package Makefile. This will override the package's own libtool in most cases. For older libtool using packages, libtool is made by ltconfig script during the do-configure step; you can check the libtool script location by doing make configure; find work*/ -name libtool. LIBTOOL_OVERRIDE specifies which libtool scripts, relative to WRKSRC, to override. By default, it is set to "libtool */libtool */*/libtool". If this does not match the location of the package's libtool script(s), set it as appropriate. If you do not need *.a static libraries built and installed, then use SHLIBTOOL_OVERRIDE instead. If your package makes use of the platform independent library for loading dynamic shared objects, that comes with libtool (libltdl), you should include devel/libltdl/buildlink3.mk. Some packages use libtool incorrectly so that the package may not work or build in some circumstances. Some of the more common errors are: * The inclusion of a shared object (-module) as a dependent library in an executable or library. This in itself isn't a problem if one of two things has been done: 1. The shared object is named correctly, i.e. libfoo.la, not foo.la 2. The -dlopen option is used when linking an executable. * The use of libltdl without the correct calls to initialisation routines. The function lt_dlinit() should be called and the macro LTDL_SET_PRELOADED_SYMBOLS included in executables. 15.3.3. GNU Autoconf/Automake If a package needs GNU autoconf or automake to be executed to regenerate the configure script and Makefile.in makefile templates, then they should be executed in a pre-configure target. For packages that need only autoconf: AUTOCONF_REQD= 2.50 # if default version is not good enough USE_TOOLS+= autoconf # use "autoconf213" for autoconf-2.13 ... pre-configure: cd ${WRKSRC}; autoconf ... and for packages that need automake and autoconf: AUTOMAKE_REQD= 1.7.1 # if default version is not good enough USE_TOOLS+= automake # use "automake14" for automake-1.4 ... pre-configure: cd ${WRKSRC}; \ aclocal; autoheader; \ automake -a --foreign -i; autoconf ... Packages which use GNU Automake will almost certainly require GNU Make. There are times when the configure process makes additional changes to the generated files, which then causes the build process to try to re-execute the automake sequence. This is prevented by touching various files in the configure stage. If this causes problems with your package you can set AUTOMAKE_OVERRIDE= NO in the package Makefile. 15.4. Building considerations 15.4.1. CPP defines To port an application to NetBSD, it's usually necessary for the compiler to be able to judge the system on which it's compiling, and we use definitions so that the C pre-processor can do this. To test whether you are working on a 4.4 BSD-derived system, you should use the BSD definition, which is defined in on said systems. #include and then you can surround the BSD-specific parts of your package's C/C++ code using this conditional: #if (defined(BSD) && BSD >= 199306) ... #endif Please use the "__NetBSD__" definition sparingly - it should only apply to features of NetBSD that are not present in other 4.4-lite derived BSDs. 15.5. Package specific actions 15.5.1. User interaction Occasionally, packages require interaction from the user, and this can be in a number of ways: * help in fetching the distfiles * help to configure the package before it is built * help during the build process * help during the installation of a package The INTERACTIVE_STAGE definition is provided to notify the pkgsrc mechanism of an interactive stage which will be needed, and this should be set in the package's Makefile. e.g. INTERACTIVE_STAGE= build Multiple interactive stages can be specified: INTERACTIVE_STAGE= configure install 15.5.2. Handling licenses A package may underly a license which the user has or has not agreed to accept. Usually, packages that underly well-known Open Source licenses (e.g. the GNU Public License, GPL) won't have any special license tags added in pkgsrc which require special action by the user of such packages, but there are quite a number of other licenses out there that pkgsrc users may not be able to follow, for whatever reasons. For these cases, pkgsrc contains a mechanism to note that a package underlies a certain license, and the user has to accept the license before the package can be installed. Placing a certain package under a certain license works by setting the LICENSE variable to a string identifying the license, e.g. in graphics/graphviz: LICENSE= graphviz-license When trying to build, the user will get a notice that the package underlies a license which he hasn't accepted (yet): % make ===> graphviz-1.12 has an unacceptable license: graphviz-license. ===> To build this package, add this line to your /etc/mk.conf: ===> ACCEPTABLE_LICENSES+=graphviz-license ===> To view the license, enter "/usr/bin/make show-license". *** Error code 1 The license can be viewed with make show-license, and if it is considered appropriate, the line printed above can be added to /etc/mk.conf to indicate acceptance of the particular license: ACCEPTABLE_LICENSES+=graphviz-license When adding a package with a new license, the license text should be added to pkgsrc/licenses for displaying. A list of known licenses can be seen in this directory as well as by looking at the list of (commented out) ACCEPTABLE_LICENSES variable settings in pkgsrc/mk/defaults/mk.conf. If there is a really pressing need to accept all licenses at once, like when trying to download or mirror all distfiles or doing a bulk build to test if all packages in pkgsrc build, this can be done by setting _ACCEPTABLE=yes. 15.5.3. Installing score files Certain packages, most of them in the games category, install a score file that allows all users on the system to record their highscores. In order for this to work, the binaries need to be installed setgid and the score files owned by the appropriate group and/or owner (traditionally the "games" user/group). The following variables, documented in more detail in mk/defaults/mk.conf, control this behaviour: SETGIDGAME, GAMEDATAMODE, GAMEGRP, GAMEMODE, GAMEOWN. Note that per default, setgid installation of games is disabled; setting SETGIDGAME=YES will set all the other variables accordingly. A package should therefor never hard code file ownership or access permissions but rely on INSTALL_GAME and INSTALL_GAME_DATA to set these correctly. 15.5.4. Packages containing perl scripts If your package contains interpreted perl scripts, set REPLACE_PERL to ensure that the proper interpreter path is set. REPLACE_PERL should contain a list of scripts, relative to WRKSRC, that you want adjusted. 15.5.5. Packages with hardcoded paths to other interpreters Your package may also contain scripts with hardcoded paths to other interpreters besides (or as well as) perl. To correct the full pathname to the script interpreter, you need to set the following definitions in your Makefile (we shall use tclsh in this example): REPLACE_INTERPRETER+= tcl _REPLACE.tcl.old= .*/bin/tclsh _REPLACE.tcl.new= ${PREFIX}/bin/tclsh _REPLACE_FILES.tcl= ...list of tcl scripts which need to be fixed, relative to ${WRKSRC}, just as in REPLACE_PERL 15.5.6. Packages installing perl modules Makefiles of packages providing perl5 modules should include the Makefile fragment ../../lang/perl5/module.mk. It provides a do-configure target for the standard perl configuration for such modules as well as various hooks to tune this configuration. See comments in this file for details. Perl5 modules will install into different places depending on the version of perl used during the build process. To address this, pkgsrc will append lines to the PLIST corresponding to the files listed in the installed .packlist file generated by most perl5 modules. This is invoked by defining PERL5_PACKLIST to a space-separated list of paths to packlist files, e.g.: PERL5_PACKLIST= ${PERL5_SITEARCH}/auto/Pg/.packlist The variables PERL5_SITELIB, PERL5_SITEARCH, and PERL5_ARCHLIB represent the three locations in which perl5 modules may be installed, and may be used by perl5 packages that don't have a packlist. These three variables are also substituted for in the PLIST. 15.5.7. Packages installing info files Some packages install info files or use the "makeinfo" or "install-info" commands. Each of the info files: * is considered to be installed in the directory ${PREFIX}/${INFO_DIR}, * is registered in the Info directory file ${PREFIX}/${INFO_DIR}/dir, * and must be listed as a filename in the INFO_FILES variable in the package Makefile. INFO_DIR defaults to "info" and can be overridden in the package Makefile. INSTALL and DEINSTALL scripts will be generated to handle registration of the info files in the Info directory file. The "install-info" command used for the info files registration is either provided by the system, or by a special purpose package automatically added as dependency if needed. A package which needs the "makeinfo" command at build time must define the variable USE_MAKEINFO in its Makefile. If a minimum version of the "makeinfo" command is needed it should be noted with the TEXINFO_REQD variable in the package Makefile. By default, a minimum version of 3.12 is required. If the system does not provide a makeinfo command or if it does not match the required minimum, a build dependency on the devel/gtexinfo package will be added automatically. The build and installation process of the software provided by the package should not use the install-info command as the registration of info files is the task of the package INSTALL script, and it must use the appropriate makeinfo command. To achieve this goal the pkgsrc infrastructure creates overriding scripts for the install-info and makeinfo commands in a directory listed early in PATH. The script overriding install-info has no effect except the logging of a message. The script overriding makeinfo logs a message and according to the value of USE_MAKEINFO and TEXINFO_REQD either run the appropriate makeinfo command or exit on error. 15.5.8. Packages installing GConf2 data files If a package installs .schemas or .entries files, used by GConf2, you need to take some extra steps to make sure they get registered in the database: 1. Include ../../devel/GConf2/schemas.mk instead of its buildlink3.mk file. This takes care of rebuilding the GConf2 database at installation and deinstallation time, and tells the package where to install GConf2 data files using some standard configure arguments. It also disallows any access to the database directly from the package. 2. Ensure that the package installs its .schemas files under ${PREFIX}/share/ gconf/schemas. If they get installed under ${PREFIX}/etc, you will need to manually patch the package. 3. Check the PLIST and remove any entries under the etc/gconf directory, as they will be handled automatically. See Section 7.14, "How do I change the location of configuration files?" for more information. 4. Define the GCONF2_SCHEMAS variable in your Makefile with a list of all .schemas files installed by the package, if any. Names must not contain any directories in them. 5. Define the GCONF2_ENTRIES variable in your Makefile with a list of all .entries files installed by the package, if any. Names must not contain any directories in them. 15.5.9. Packages installing scrollkeeper data files If a package installs .omf files, used by scrollkeeper, you need to take some extra steps to make sure they get registered in the database: 1. Include ../../textproc/scrollkeeper/omf.mk instead of its buildlink3.mk file. This takes care of rebuilding the scrollkeeper database at installation and deinstallation time, and disallows any access to it directly from the package. 2. Check the PLIST and remove any entries under the libdata/scrollkeeper directory, as they will be handled automatically. 3. Remove the share/omf directory from the PLIST. It will be handled by scrollkeeper. 15.5.10. Packages installing X11 fonts If a package installs font files, you will need to rebuild the fonts database in the directory where they get installed at installation and deinstallation time. This can be automatically done by using mk/fonts.mk, which you need to include in your Makefile. When the file is included, you can list the directories where fonts are installed in the FONTS_type_DIRS variables, where type can be one of "TTF", "TYPE1" or "X11". Also make sure that the database file fonts.dir is not listed in the PLIST. Note that you should not create new directories for fonts; instead use the standard ones to avoid that the user needs to manually configure his X server to find them. 15.5.11. Packages installing GTK2 modules If a package installs gtk2 immodules or loaders, you need to take some extra steps to get them registered in the GTK2 database properly: 1. Include ../../x11/gtk2/modules.mk instead of its buildlink3.mk file. This takes care of rebuilding the database at installation and deinstallation time. 2. Set GTK2_IMMODULES=YES if your package installs GTK2 immodules. 3. Set GTK2_LOADERS=YES if your package installs GTK2 loaders. 4. Patch the package to not touch any of the gtk2 databases directly. These are: * libdata/gtk-2.0/gdk-pixbuf.loaders * libdata/gtk-2.0/gtk.immodules 5. Check the PLIST and remove any entries under the libdata/gtk-2.0 directory, as they will be handled automatically. 15.5.12. Packages installing SGML or XML data If a package installs SGML or XML data files that need to be registered in system-wide catalogs (like DTDs, sub-catalogs, etc.), you need to take some extra steps: 1. Include ../../textproc/xmlcatmgr/catalogs.mk in your Makefile, which takes care of registering those files in system-wide catalogs at installation and deinstallation time. 2. Set SGML_CATALOGS to the full path of any SGML catalogs installed by the package. 3. Set XML_CATALOGS to the full path of any XML catalogs installed by the package. 4. Set SGML_ENTRIES to individual entries to be added to the SGML catalog. These come in groups of three strings; see xmlcatmgr(1) for more information (specifically, arguments recognized by the 'add' action). Note that you will normally not use this variable. 5. Set XML_ENTRIES to individual entries to be added to the XML catalog. These come in groups of three strings; see xmlcatmgr(1) for more information (specifically, arguments recognized by the 'add' action). Note that you will normally not use this variable. 15.5.13. Packages installing extensions to the MIME database If a package provides extensions to the MIME database by installing .xml files inside ${PREFIX}/share/mime/packages, you need to take some extra steps to ensure that the database is kept consistent with respect to these new files: 1. Include ../../databases/shared-mime-info/mimedb.mk (avoid using the buildlink3.mk file from this same directory, which is reserved for inclusion from other buildlink3.mk files). It takes care of rebuilding the MIME database at installation and deinstallation time, and disallows any access to it directly from the package. 2. Check the PLIST and remove any entries under the share/mime directory, except for files saved under share/mime/packages. The former are handled automatically by the update-mime-database program, but the later are package-dependent and must be removed by the package that installed them in the first place. 3. Remove any share/mime/* directories from the PLIST. They will be handled by the shared-mime-info package. 15.5.14. Packages using intltool If a package uses intltool during its build, include the ../../textproc/ intltool/buildlink3.mk file, which forces it to use the intltool package provided by pkgsrc, instead of the one bundled with the distribution file. This tracks intltool's build-time dependencies and uses the latest available version; this way, the package benefits of any bug fixes that may have appeared since it was released. 15.5.15. Packages installing startup scripts If a package contains a rc.d script, it won't be copied into the startup directory by default, but you can enable it, by adding the option PKG_RCD_SCRIPTS=YES in /etc/mk.conf. This option will copy the scripts into / etc/rc.d when a package is installed, and it will automatically remove the scripts when the package is deinstalled. 15.6. Feedback to the author If you have found any bugs in the package you make available, if you had to do special steps to make it run under NetBSD or if you enhanced the software in various other ways, be sure to report these changes back to the original author of the program! With that kind of support, the next release of the program can incorporate these fixes, and people not using the NetBSD packages system can win from your efforts. Support the idea of free software! Chapter 16. Debugging To check out all the gotchas when building a package, here are the steps that I do in order to get a package working. Please note this is basically the same as what was explained in the previous sections, only with some debugging aids. * Be sure to set PKG_DEVELOPER=1 in /etc/mk.conf * Install pkgtools/url2pkg, create a directory for a new package, change into it, then run url2pkg: % mkdir /usr/pkgsrc/category/examplepkg % cd /usr/pkgsrc/category/examplepkg % url2pkg http://www.example.com/path/to/distfile.tar.gz * Edit the Makefile as requested. * Fill in the DESCR file * Run make configure * Add any dependencies glimpsed from documentation and the configure step to the package's Makefile. * Make the package compile, doing multiple rounds of % make % pkgvi ${WRKSRC}/some/file/that/does/not/compile % mkpatches % patchdiff % mv ${WRKDIR}/.newpatches/* patches % make mps % make clean Doing as non-root user will ensure that no files are modified that shouldn't be, especially during the build phase. mkpatches, patchdiff and pkgvi are from the pkgtools/pkgdiff package. * Look at the Makefile, fix if necessary; see Section 8.1, "Makefile". * Generate a PLIST: # make install # make print-PLIST >PLIST # make deinstall # make install # make deinstall You usually need to be root to do this. Look if there are any files left: # make print-PLIST If this reveals any files that are missing in PLIST, add them. * Now that the PLIST is OK, install the package again and make a binary package: # make reinstall # make package * Delete the installed package: # pkg_delete blub * Repeat the above make print-PLIST command, which shouldn't find anything now: # make print-PLIST * Reinstall the binary package: # pkgadd .../blub.tgz * Play with it. Make sure everything works. * Run pkglint from pkgtools/pkglint, and fix the problems it reports: # pkglint * Submit (or commit, if you have cvs access); see Chapter 17, Submitting and Committing. Chapter 17. Submitting and Committing Table of Contents 17.1. Submitting your packages 17.2. General notes when adding, updating, or removing packages 17.3. Committing: Importing a package into CVS 17.4. Updating a package to a newer version 17.5. Moving a package in pkgsrc 17.1. Submitting your packages You have to separate between binary and "normal" (source) packages here: * precompiled binary packages Our policy is that we accept binaries only from pkgsrc developers to guarantee that the packages don't contain any trojan horses etc. This is not to annoy anyone but rather to protect our users! You're still free to put up your home-made binary packages and tell the world where to get them. NetBSD developers doing bulk builds and wanting to upload them please see Section 6.3.8, "Uploading results of a bulk build". * packages First, check that your package is complete, compiles and runs well; see Chapter 16, Debugging and the rest of this document. Next, generate an uuencoded gzipped tar(1) archive, preferably with all files in a single directory. Finally, send-pr with category "pkg", a synopsis which includes the package name and version number, a short description of your package (contents of the COMMENT variable or DESCR file are OK) and attach the archive to your PR. If you want to submit several packages, please send a separate PR for each one, it's easier for us to track things that way. Alternatively, you can also import new packages into pkgsrc-wip ("pkgsrc work-in-progress"); see the homepage at http://pkgsrc-wip.sourceforge.net/ for details. 17.2. General notes when adding, updating, or removing packages Please note all package additions, updates, moves, and removals in pkgsrc/doc/ CHANGES. It's very important to keep this file up to date and conforming to the existing format, because it will be used by scripts to automatically update pages on www.NetBSD.org and other sites. Additionally, check the pkgsrc/doc/ TODO file and remove the entry for the package you updated or removed, in case it was mentioned there. There is a make target that helps in creating proper CHANGES entries: make changes-entry. It uses the optional CTYPE and NETBSD_LOGIN_NAME variables. The general usage is to first make sure that your CHANGES file is up-to-date (to avoid having to resolve conflicts later-on) and then to cd to the package directory. For package updates, make changes-entry is enough. For new packages, or package moves or removals, set the CTYPE variable on the command line to "Added", "Moved", or "Removed". You can set NETBSD_LOGIN_NAME in /etc/mk.conf if your local login name is not the same as your NetBSD login name. Don't forget to commit the changes to pkgsrc/doc/CHANGES! 17.3. Committing: Importing a package into CVS This section is only of interest for pkgsrc developers with write access to the pkgsrc repository. Please remember that cvs imports files relative to the current working directory, and that the pathname that you give the cvs import command is so that it knows where to place the files in the repository. Newly created packages should be imported with a vendor tag of "TNF" and a release tag of "pkgsrc-base", e.g: % cd .../pkgsrc/category/pkgname % cvs import pkgsrc/category/pkgname TNF pkgsrc-base Remember to move the directory from which you imported out of the way, or cvs will complain the next time you "cvs update" your source tree. Also don't forget to add the new package to the category's Makefile. The commit message of the initial import should include part of the DESCR file, so people reading the mailing lists know what the package is/does. For new packages, "cvs import" is preferred to "cvs add" because the former gets everything with a single command, and provides a consistent tag. 17.4. Updating a package to a newer version Please always put a concise, appropriate and relevant summary of the changes between old and new versions into the commit log when updating a package. There are various reasons for this: * A URL is volatile, and can change over time. It may go away completely or its information may be overwritten by newer information. * Having the change information between old and new versions in our CVS repository is very useful for people who use either cvs or anoncvs. * Having the change information between old and new versions in our CVS repository is very useful for people who read the pkgsrc-changes mailing list, so that they can make tactical decisions about when to upgrade the package. Please also recognize that, just because a new version of a package has been released, it should not automatically be upgraded in the CVS repository. We prefer to be conservative in the packages that are included in pkgsrc - development or beta packages are not really the best thing for most places in which pkgsrc is used. Please use your judgement about what should go into pkgsrc, and bear in mind that stability is to be preferred above new and possibly untested features. 17.5. Moving a package in pkgsrc 1. Make a copy of the directory somewhere else. 2. Remove all CVS dirs. Alternatively to the first two steps you can also do: % cvs -d user@cvs.NetBSD.org:/cvsroot export -D today pkgsrc/category/package and use that for further work. 3. Fix CATEGORIES and any DEPENDS paths that just did "../package" instead of "../../category/package". 4. cvs import the modified package in the new place. 5. Check if any package depends on it: % cd /usr/pkgsrc % grep /package */*/Makefile* */*/buildlink* 6. Fix paths in packages from step 5 to point to new location. 7. cvs rm (-f) the package at the old location. 8. Remove from oldcategory/Makefile. 9. Add to newcategory/Makefile. 10. Commit the changed and removed files: % cvs commit oldcategory/package oldcategory/Makefile newcategory/Makefile (and any packages from step 5, of course). Appendix A. A simple example package: bison Table of Contents A.1. files A.1.1. Makefile A.1.2. DESCR A.1.3. PLIST A.1.4. Checking a package with pkglint A.2. Steps for building, installing, packaging We checked to find a piece of software that wasn't in the packages collection, and picked GNU bison. Quite why someone would want to have bison when Berkeley yacc is already present in the tree is beyond us, but it's useful for the purposes of this exercise. A.1. files A.1.1. Makefile # $NetBSD$ # DISTNAME= bison-1.25 CATEGORIES= devel MASTER_SITES= ${MASTER_SITE_GNU} MAINTAINER= thorpej@NetBSD.org HOMEPAGE= http://www.gnu.org/software/bison/bison.html COMMENT= GNU yacc clone GNU_CONFIGURE= yes INFO_FILES= bison.info .include "../../mk/bsd.pkg.mk" A.1.2. DESCR GNU version of yacc. Can make re-entrant parsers, and numerous other improvements. Why you would want this when Berkeley yacc(1) is part of the NetBSD source tree is beyond me. A.1.3. PLIST @comment $NetBSD$ bin/bison man/man1/bison.1.gz share/bison.simple share/bison.hairy A.1.4. Checking a package with pkglint The NetBSD package system comes with pkgtools/pkglint which helps to check the contents of these files. After installation it is quite easy to use, just change to the directory of the package you wish to examine and execute pkglint: $ pkglint looks fine. Depending on the supplied command line arguments (see pkglint(1)) more verbose checks will be performed. Use e.g. pkglint -v for a very verbose check. A.2. Steps for building, installing, packaging Create the directory where the package lives, plus any auxiliary directories: # cd /usr/pkgsrc/lang # mkdir bison # cd bison # mkdir patches Create Makefile, DESCR and PLIST (see Chapter 8, Package components - files, directories and contents) then continue with fetching the distfile: # make fetch >> bison-1.25.tar.gz doesn't seem to exist on this system. >> Attempting to fetch from ftp://prep.ai.mit.edu/pub/gnu//.

Procedure This section contains information on editing the pkgsrc guide itself. D.1. Targets The pkgsrc guide's source code is stored in pkgsrc/doc/guide/files, and several files are created from it: * pkgsrc/doc/pkgsrc.txt * pkgsrc/doc/pkgsrc.html * http://www.NetBSD.org/Documentation/pkgsrc/: the documentation on the NetBSD website will be built from pkgsrc and kept up to date on the web server itself. This means you must make sure that your changes haven't broken the build! * http://www.NetBSD.org/Documentation/pkgsrc/pkgsrc.pdf: PDF version of the pkgsrc guide. * http://www.NetBSD.org/Documentation/pkgsrc/pkgsrc.ps: PostScript version of the pkgsrc guide. D.2. Procedure The procedure to edit the pkgsrc guide is: * Make sure you have the packages needed to re-generate the pkgsrc guide (and other XML-based NetBSD documentation) installed. These are "netbsd-doc" for creating the ASCII- and HTML-version, and "netbsd-doc-print"for the PostScript- and PDF version. You will need both packages installed, to make sure documentation is consistent across all formats. The packages can be found in pkgsrc/meta-pkgs/netbsd-doc and pkgsrc/meta-pkgs/netbsd-doc-print. * Edit the XML file(s) in pkgsrc/doc/guide/files. * Run make extract && make do-lint in pkgsrc/doc/guide to check the XML syntax, and fix it if needed. * Run make in pkgsrc/doc/guide to build the HTML and ASCII version. * If all is well, run make install-doc to put the generated files into pkgsrc /doc. * cvs commit pkgsrc/doc/guide/files * cvs commit -m re-generate pkgsrc/doc/pkgsrc.{html,txt} * Until the webserver on www.NetBSD.org is really updated automatically to pick up changes to the pkgsrc guide automatically, also run make install-htdocs HTDOCSDIR=../../../htdocs (or similar, adjust HTDOCSDIR!). * cvs commit htdocs/Documentation/pkgsrc
