 This file is intended to be a brief introduction to the build  This file (UPDATING) is intended to be a brief reference to recent
 process and a reference on what to do if something doesn't work.  changes that might cause problems in the build process, and a guide for
   what to do if something doesn't work.
   
   For a more detailed description of the recommended way to build NetBSD
   using build.sh, see the BUILDING file.
   
   Note that much of the advice in this UPDATING file was written before
   build.sh existed.  Nevertheless, the advice here may be useful for
   working around specific problems with build.sh.

 20040516:  20081205:
         The end-user modifiable X11 configuration has been moved          If you build with MKX11=no, you should remove /etc/rc.d/xdm and
         from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.          /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc

         consumers of the create and delete interface, as well as          Since this breaks the libc build itself, manual help is
         the dynamic discovery mechanism.  This is believed only to          needed -- lint must be disabled temporarily, e.g:

         cd lib/libc          especially an uncleanly mounted journaled filesystem.  WAPBL

         kernel has COMPAT_16 enabled before building userland.          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so

                 cd src/gnu/usr.bin/groff          kernel (version 4.99.10), then you also need a new pthread
                 make MKMAN=no dependall install          library (/usr/lib/libpthread.so.0.7).  If you boot with
         (untested).          an old kernel, then you need the old pthread library
           (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
 20030516:          the pthread library in sync, old threaded applications should

         were accepted before and caused the kernel to panic when          is the only threaded application in the base system.
         mountd got restarted because it freed memory that had already  
         been freed. This has been fixed and the kernel checks  20061214:
         export addresses very strictly. If you upgrade your kernel,          Following the move of string_to_flags() and flags_to_string()
         make sure you also upgrade mountd, because if your export          from the bin/ls/ sources to libutil, users doing UPDATE builds

         The superblock layout for FFS was changed.  If you have 1.6                  as the installation images in distrib/

         fields (even ones that aren't useful).  If possible, upgrade  
         your fsck_ffs binary before using a new kernel.  20061108:
         None of this signals actual filesystem damage.          The configure script used in the src/tools/gcc compiler has been
           changed to indicate that our libc has ssp support built-in and

         is named netbsd-msp.cf.  Upgrading your regular sendmail  
         configuration file is also strongly advised.  20060814:
           The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
         See the section named "MESSAGE SUBMISSION PROGRAM" in          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         the updated /usr/share/sendmail/README file for more          kernel configuration for an example.  X servers from the last
         information.          few years should cope.
   
 20030117:  20060703:
         Texinfo was updated to 4.3.  To avoid failures when trying to          MPACPI is no more. We always configure PCI interrupts using ACPI
         build the included texinfo files, do:          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
           to ACPI_SCANPCI. Thanks to work from fvdl.
         cd src/gnu/usr.bin/texinfo  
         make MKINFO=no dependall install  20060627:
           socket(2) has changed, and its system call has been versioned.
 20021223:          For userlands with the old version of socket(2), make sure that
         The METALOG format changed slightly, to remove the leading          your kernel has 'options COMPAT_30' set, or else 'bad system call'
         "${DESTDIR}" from path names.          errors will result.
         This only affects people building with UNPRIVED.  
         For complete safety, remove the DESTDIR entirely and  
         update tools/mtree, before running make build.  
   
 20021219:  
         CVS repository layout was changed.  See the following for details  
         if you are using (anonymous) cvs to update your tree.  
   
         http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html  
   
 20021219:  
         install(1) had a '-N dbdir' option added, to specify an  
         alternate location to look up users & groups (instead  
         of the host system passwd(5) and group(5) databases).  
   
         The build system was modified to take advantage of  
         this option (using ${NETBSDSRCDIR}/etc), so if you  
         use USETOOLS==no, you may have to rebuild and  
         reinstall usr.bin/xinstall first.  
   
 20021130:  
         fparseln(3) moved from libutil to libc.  
         If building to DESTDIR=/, reinstall the includes  
         and rebuild libc:  
                 make includes  
                 make do-lib-libc  
         If using build.sh, "cd tools/compat && make clean"  
         before rebuilding the tools.  
   
 20021126:  
         The mk.conf(5) variable SYS_INCLUDE has been deprecated,  
         including the optional "SYS_INCLUDE=symlinks" support.  
         All header files, including <sys/*.h> are copied into  
         /usr/include.  
   
 20021121:  
         The C run-time support files crtbegin.o and crtend.o  
         (and their companions crtbeginS.o and crtendS.o) were  
         split up, with new crti.o and crtn.o files resulting.  
         This means that libtool needs to be rebuilt once the  
         new libraries are installed.  The process of rebuilding  
         libtool will cause it to automatically notice the new  
         required files, but it *must* be rebuilt in order to  
         do this.  
   
         An out-of-date libtool will result in shared libraries  
         which lack _init() and _fini() routines, which means that  
         their global contructors/destructors will not be invoked.  
   
 20021121:  
         A bug related to how ARM ELF objects were tagged has been  
         corrected.  
   
         NetBSD ARM ELF uses the soft-VFP floating point model by  
         default.  However, the assembler lacked support for marking  
         objects as using the VFP floating point format, and the  
         compiler was not properly passing the flag indicating "soft-VFP"  
         to the assembler.  
   
         Unfortunately, this means that the linker will now consider  
         old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be  
         incompatible with new (properly marked) objects.  
   
         The problem will only manifest itself if you attempt to compile  
         a new program using the fixed toolchain, and link that program  
         against old libraries which do not have the proper "softvfp"  
         markings.  ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES  
         WILL CONTINUE TO WORK PROPERLY.  
   
         The only work-around for the problem is to recompile all of  
         the libraries on the system.  The easiest way to do this for  
         system libraries is to install a binary snapshot; they are  
         generally available on releng.NetBSD.org.  Any packages you  
         have installed which supply libraries will have to be recompiled  
         if you wish to link new programs against those libraries.  
   
         If you have questions about this matter, please contact  
         port-arm@NetBSD.org.  
   
 20021011:  
         Systrace has been improved to support privilege elevation.  
         Updating the kernel requires the userland part of systrace  
         to be rebuilt.  
   
 20021010:  
         The config(8) grammar was changed to allow options to register  
         dependencies on attributes, as well as other options.  Users  
         must update and reinstall usr.sbin/config before building a new  
         kernel.  
   
 20021009:  
         A new attribute dependency syntax was introduced to config(8),  
         which is now used by the SCSI configuration description.  Users  
         must update and reinstall usr.sbin/config before building a new  
         kernel.  
   
 20021003:  
         Several changes have been made to the autoconfiguration  
         framework.  Users must update and reinstall usr.sbin/config  
         before building a new kernel.  
   
 20021001:  
         The i386mp branch has been merged.  To compile a kernel, users  
         will need to add the option 'cpu* at mainbus?' to their configuration  
         file.  Multiprocessor kernels will need  
         ioapic*         at mainbus? apid ?  
         options         MULTIPROCESSOR  
         options         COM_MPLOCK  
   
 20020922:  
         MKDYNAMICROOT=yes enabled by default, which means that  
         certain shared libraries are installed into /lib, the shared  
         linker is installed into /libexec, and all programs in /bin  
         and /sbin are dynamically linked.  
         If you do not use "make build", you should ensure that  
         you have the libraries and shared linker in the new locations,  
         with:  
                 make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so  
   
 20020917:  
         USE_NEW_TOOLCHAIN has been replaced with:  
             -   TOOLCHAIN_MISSING -- set to "yes" on platforms for which  
                 there is no working in-tree toolchain (hppa, ns32k, sh5,  
                 x86_64).  
             -   EXTERNAL_TOOLCHAIN -- if defined by the user, points to the  
                 root of an external toolchain (e.g. /usr/local/gnu).  This  
                 enables the cross-build framework even for TOOLCHAIN_MISSING  
                 platforms.  
   
 20020906:  
         gehenna-devsw has been merged into the trunk. Need to update and  
         reinstall usr.sbin/config before building the kernel.  
   
 20020822:  
         Crunched rescue tools (contents of /bin and /sbin, plus others)  
         are now provided in /rescue.  
   
         To ensure that these are built statically linked (no matter  
         what the setting of LDSTATIC is), use a crunchgen(1) built  
         from sources newer than 20020820 (see the next entry).  
   
 20020820:  
         crunchgen(1) changed to ensure that the generated program  
         is statically linked.  
   
         Solution: update and reinstall usr.bin/crunch  
   
 20020605:  
         smmsp user/group has been added for sendmail.  
   
         Add the following into /etc/group:  
   
         smmsp:*:17:  
   
         and the following to /etc/master.passwd (via vipw):  
   
         smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin  
   
 20020515:  
         sshd user/group has been added.  Need to hand add this in, or sshd  
         will not let you log in (with default, or UsePrivlegeSeparation=yes)  
   
         Add the following into /etc/group:  
   
         sshd:*:16:  
   
         and the following to /etc/master.passwd (via vipw):  
   
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin  
   
         Also /var/chroot/sshd directory needs to be present (digged as part of  
         the build process).  
   
 20020426:  
         NBUILDJOBS obsoleted in favor of just using -j.  
   
 20020426:  
         etc/postinstall added, which performs various checks for  
         configuration file updates and changes, and can fix most of  
         the problems identified.  
         This should make it much easier to upgrade a system's  
         configuration from earlier systems (as far back as NetBSD 1.5).  
   
 20020320:  
         <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.  
         Build and install at usr.bin/xinstall before the build.  
   
 20020319:  
         Raw IPv6 socket now makes strict checking for sa_family and sa_len  
         on send(2) operation.  Be sure to have sbin/rtsol and usr.sbin/rtsold  
         newer than November 2001 when you upgrade the kernel.  
   
 20020311:  
         ssh configuration files were moved from /etc to /etc/ssh.  Beware  
         if you restart your machine from remote.  Note that sshd.conf needs  
         to be changed (due to the use of "/etc" inside).  
   
 20020223:  
         Users of the VAX port will need to rebuild and install gas  
         so it deal with the now present register prefix used in all  
         the VAX assembly files.  
   
 20020118:  
         ntpd user/group has been added.  Need to hand add this in or builds  
         will break as mtree aborts early.  
   
         Add the following into /etc/group:  
   
         ntpd:*:15:  
   
         and the following to /etc/master.passwd (via vipw):  
   
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin  
   
 20011207:  
         If you're attempting to build a snapshot on sparc64 and are getting  
         reloc errors from the toolchain groff binary this means your native  
         toolchain has some broken C++ bits.  
   
         To fix:  
   
         Build a new toolchain (i.e. build.sh -t)  
         Use the new toolchain to build and install natively (i.e. /usr/lib)  
   
         gnu/lib/libgcc  
         gnu/lib/libstdc++  
   
         After this a snapshot will be able to be built.  
   
 20011201:  
         In order for a sparc64 build to work you must have a working awk. If  
         you've built and installed a system with the new toolchain up to this  
         point you do not have a working awk as its ability to do floating  
         point is broken.  
   
         To build:  
   
         remake and install gnu/lib/libgcc  
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links  
         against the new libgcc.a)  
   
 20011128:  
         Kernel config information was changed to use defflag in  
         the various "files" files.  Bug fixes to config(8) are  
         required in order for this to work properly.  Make sure  
         to build and install in usr.sbin/config before attempting  
         to build a new kernel.  
   
 20011030:  
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)  
         before building libc.  
   
 20011029:  
         The new document BUILDING.mdoc (view with nroff | more, or  
         see pre-generated .txt and .html versions) describes the build  
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN  
         build process, are intended in the long run to replace this  
         manual update log.  
   
         Users building a USE_NEW_TOOLCHAIN system should read the  
         BUILDING document for caveats.  Generally, BUILDING supersedes  
         UPDATING for these systems, as tool updating is taken care of  
         by the new build system.  
   
 20011028:  
         src/etc/Makefile now needs install to be able to handle  
         symlinks that point to nowhere. A bug in install that  
         prevented this was corrected.  
   
         Solution: update and reinstall usr.bin/xinstall  
         Better Solution: Use the new toolchain and it will just work  
         for you.  
   
 20011006:  
         /etc/mtree/NetBSD.dist has been updated to take advantage of  
         absolute path support added to mtree(8). Older mtree(8)s don't  
         understand the format.  
   
         Solution: update and reinstall usr.sbin/mtree  
   
 20011004:  
         Crunchgen has been updated to work via reach-over makefiles. Updating  
         is suggested before running a snapshot build  
   
 20010915:  
         The new "ubcperf" code committed by Chuck Silvers removed  
         a header file, uvm/uvm_vnode.h.  There may be stale .depend  
         files that still reference this file.  
   
         Solution: "make cleandir && make dependall" in affected  
         directories.  
   
 20010803:  
         grep.info is now built from grep.texi using makeinfo.  Since it  
         requires makeinfo v4.0, you need to install new texinfo before  
         building gnu/usr.bin/grep.  To install new texinfo, please follow  
         the instruction described in 20010726 entry.  
   
 20010803:  
         (i386 only): i386 kernel now uses new instructions like  
         `fxsave' which old gas doesn't understand.  To build the  
         kernel successfully, you need to build and install a new toolchain,  
         (i.e., build.sh -t) or  (temporarily) comment out "options I686_CPU"  
         from your kernel configuration until you rebuild your userland.  
         See 20011029 above and BUILDING file in this directory for more information.  
         [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]  
   
 20010731:  
         Bootloader update on ELF platforms.  DDB in kernels from before  
         this will be unable to read symbol tables provided by newer  
         bootloaders.  
   
 20010726:  
         Texinfo was updated to 4.0.  To avoid failures when trying to  
         build the included texinfo files, do:  
   
         cd src/gnu/usr.bin/texinfo  
         make MKINFO=no dependall install  
   
 20010718:  
         Enabled correct .init/.fini processing in crt0.  The way this  
         was done was to change a -I directive to cc(1), which means  
         make(1) will have a stale dependency (it will be checking the  
         timestamp on the wrong "dot_init.h").  
   
         The symptom you will see is that new programs die with SIGSEGV  
         if you have a stale dependency.  
   
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so  
         before starting your build.  
   
 20010628:  
         A construct was added to uvm_page.h that uncovered a bug  
         in lint(1).  If you get a warning/error about a non-portable  
         bitfield, update your lint(1) before proceeding.  
   
 20010226:  
         Added named user/group to system. Need to hand add this in or builds  
         will break as mtree aborts early.  
   
         To work around add by hand:  
   
         named:*:14:  
   
         to /etc/group and add:  
   
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin  
   
         to master.passwd (use vipw for instance if doing by hand).  
   
         Now a make build should progress.  
   
 20010219:  
         get/setprogname() added. Any hostprogs that may use this will need  
         to be bootstrapped manually until the host system is current.  
   
         Known problems: sys/arch/macppc/stand/fixcoff  
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to  
                           CFLAGS and rebuilding should work)  
                         usr.sbin/mdsetimage - Build a static copy if  
                           building a snapshot before fully bootstrapped.  
   
 20010204:  
         prepare the code to compile with stricter gcc flags. in  
         particular start eliminating redundant declarations. Yacc  
         needs to be installed before make build.  
   
 20010114:  
         introduce .if commands(target) in make(1). You need to  
         bring everything up-to-date first, then without installing  
         anything make and install in usr.bin/make, then proceed  
         with make build.  
   
 20010101:  
         bsd.subdir.mk committed 20001230 had a bug which caused  
         afterinstall targets to run too soon; update again.  
   
 20001230:  
         New share/mk files needed to support .WAIT in SUBDIR variables.  
         If you get make errors,  
                 (cd share/mk; make install)  
         Also, PRINTOBJDIR has changed and is now used more heavily.  
   
 20001019:  
         The `ca' device driver has been replaced by `ld'; although the  
         major and minor numbers haven't changed, you should update your /dev  
         directory.  
   
 20000929:  
         The following make directives are obsoleted.  
         MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA  
         By default, RSA is built into libcrypto.  IDEA and RC5 will not be  
         built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build  
         additional library libcrypto_{idea,rc5}.
