 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.

 ^^^^^^^^^^^^^^^  ^^^^^^^^^^^^^^^
   20110117:
 20020917:          Assembler files on the following platforms no longer use -tradition-cpp:
         USE_NEW_TOOLCHAIN has been replaced with:          - Alpha,
             -   TOOLCHAIN_MISSING -- set to "yes" on platforms for which          - AMD64,
                 there is no working in-tree toolchain (hppa, ns32k, sh5,          - i386,
                 x86_64).          - SPARC,
             -   EXTERNAL_TOOLCHAIN -- if defined by the user, points to the          - SPARC64.
                 root ofan external toolchain (e.g. /usr/local/gnu).  This          This can break the build of individual parts of the tree.  This is
                 enables the cross-build framework even for TOOLCHAIN_MISSING          handled correctly by build.sh.  Manual builds have to update
                 platforms.          /usr/share/mk and re-run config(1) for any kernel configurations as
           needed.
 20020906:  
         gehenna-devsw has been merged into the trunk. Need to update and  20101217:
         reinstall usr.sbin/config before build the kernel.          The tcpdump(8) program was changed to drop privileges and chroot(2)
           by default. It may be necessary to manually update passwd(5) and
 20020822:          group(5) in order to make the program work with existing setups.
         Crunched rescue tools (contents of /bin and /sbin, plus others)  
         are now provided in /rescue.  20101125:
           The latest changes to setenv(3) dissallow setting environment
         To ensure that these are built statically linked (no matter          variables with names that contain '='. Revision 1.18 of env.c
         what the setting of LDSTATIC is), use a crunchgen(1) built          assumed that this was allowed. Installing a new libc with an
         from sources newer than 20020820 (see the next entry).          old copy of /usr/bin/env causes env x=1 printenv | grep x= to
           break which affects the autoconf tests for dependency finding,
 20020820:          so building gcc will end up printing:
         crunchgen(1) changed to ensure that the generated program              checking dependency style of gcc... none
         is statically linked.              configure: error: no usable dependency style found
           Fix it by rebuilding and re-installing env.
         Solution: update and reinstall usr.bin/crunch  
   20101119:
 20020515:          Recent Xorg updates in xsrc/external/mit/ may cause various build
         sshd user/group has been added.  Need to hand add this in, or sshd          or run-time problems.  Delete your entire DESTDIR and OBJDIR if you
         will not let you log in (with default, or UsePrivlegeSeparation=yes)          have any build problems with xsrc, or problems with mismatched
           versions between xorg-server and drivers.
         Add the following into /etc/group:  
   20100604:
         sshd:*:16:          The update of ATF to 0.9 causes old tests written in shell to fail
           unless they are rebuilt.  If you are building with MKUPDATE=yes,
         and the following to /etc/master.passwd (via vipw):          you need to clean the src/external/bsd/atf/tests/ and the src/tests/
           trees by hand.
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin  
   20100522:

         build process).          problems.  Delete your entire DESTDIR and OBJDIR if you have any
           build problems with xsrc.
 20020426:  
         NBUILDJOBS obsoleted in favor of just using -j.  20100522:
           private section of <ctype.h> was splitted, and now mklocale(1)
 20020426:          include ctype_local.h, so you have to make cleandir in tools/mklocale.
         etc/postinstall added, which performs various checks for  
         configuration file updates and changes, and can fix most of  20100520:
         the problems identified.          The location of the xkb compiled descriptions has changed. Please

         configuration from earlier systems (as far back as NetBSD 1.5).  
   20100222:
 20020320:          The shared objects file extension has been changed from .so to
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.          .pico, in order to avoid conflicts with shared libraries names
         build and install at usr.bin/xinstall before the build.          libXX.so.  All now stale regular .so files can be removed from
           your object directories.
 20020319:  
         raw IPv6 socket now makes strict checking for sa_family and sa_len  20100204:
         on send(2) operation.  be sure to have sbin/rtsol and usr.sbin/rtsold          The termcap database has been removed from the sources,
         newer than November 2001 when you upgrade the kernel.          but has not been marked obsolete so it is not removed
           from the system when upgrading.
 20020311:          As such, you will need to remove them from your object
         ssh configuration files were moved from /etc to /etc/ssh.  Beware          and destination directories.
         if you restart your machine from remote.  Note that sshd.conf needs  
         to be changed (due to the use of "/etc" inside).  20091101:
           After updating, it may be necessary to make the 'cleandir'
 20020223:          target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
         Users of the VAX port will need to rebuild and install gas          'build.sh -u tools' or 'build.sh -u distribution'.  Ditto
         so it deal with the now present register prefix used in all          src/tools/lex/ and src/usr.bin/lex/.
         the VAX assembly files.  
   20091001:
 20020118:          On amd64 you must rebuild tools (to get the new binutils)
           before building a kernel, or the build fails on cpufunc.S.
         ntpd user/group has been added.  Need to hand add this in or builds  
         will break as mtree aborts early.  20091001:
           An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
         Add the following into /etc/group:          symlink, failing the build.  Delete the link, and the subdir
           it is in, and retry your build.
         ntpd:*:15:  
   20090718:
         and the following to /etc/master.passwd (via vipw):          libc build changed so that strchr() provides the extra entry
           point for index(). Update build of libc.a (and libc_pic.a)
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin          may fail because the archive contains the unwanted index.o.
           (Similarly for strrchr() and rindex().)
 20011207:  
   20090709:

         reloc errors from the toolchain groff binary this means your native          without a clean objdir, at least for src/external/mit/xorg.
         toolchain has some broken C++ bits.  
   20090616:
         To fix:          Native Xorg was upgraded.  Builds will need a clean objdir for
           src/external/mit/xorg.  Upgrading a system from sets will not

         Use the new toolchain to build and install natively (i.e. /usr/lib)          subdirectory has been changed into a file, and this needs to
           be manually "rm -r"'ed before installing xbase.tgz.
         gnu/lib/libgcc  
         gnu/lib/libstdc++  20090501:
           Several new functions were added to string.h/libc, and this
         After this a snapshot will be able to be built.          can cause autoconf problems during the tool build for people
           who fail to clean out their tools objects properly. If you

         you've built and installed a system with the new toolchain up to this          objects and start again.
         point you do not have a working awk as its ability to do floating  
         point is broken.  20090325:
           The i386 port was switched to i486 default toolchain.  This requires
         To build:          cleaning your src/tools directory and $TOOLDIR and rebuilding them.

         against the new libgcc.a)          need to 'rm -f __posix_fadvise50.*' in the libc build directory
           to avoid using the old assembly stub.
 20011128:  
         Kernel config information was changed to use defflag in  20090202:
         the various "files" files.  Bug fixes to config(8) are          pkg_install now depends on the pkgdb cache for automatic conflict

         to build a new kernel.  
   20090110:
 20011030:          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)          1. Make sure your kernel has COMPAT_50 in it. Build and install.
         before building libc.             This is needed even in the MODULAR kernel because there is
              conditionally compiled code in rtsock.c.
 20011029:          2. make sure build.sh completes and the binaries in a chroot work
         The new document BUILDING.mdoc (view with nroff | more, or             before installing.
         see pre-generated .txt and .html versions) describes the build          3. If you don't use build.sh and you build directly to root, and

         by the new build system.             Any package you rebuild will require rebuilding all the packages
              that depend on it.
 20011028:          5. Next time you run pwd_mkdb with the new binary, the file

              files manually.
 20011006:          7. The optional accounting file (/var/account/acct, see
         /etc/mtree/NetBSD.dist has been updated to take advantage of             accton(8)) has not been versioned, and will need to be

              the file.
         Solution: update and reinstall usr.sbin/mtree          8. Application software that writes time_t to binary files on

         is suggested before running a snapshot build  
   20081219:
 20010915:          config(1) has been updated, and one of the files it creates -
         The new "ubcperf" code committed by Chuck Silvers removed          swapnetbsd.o - has changed format.  You need to rebuild config
         a header file, uvm/uvm_vnode.h.  There may be stale .depend          (done automatically by build.sh) and then you need to rerun
         files that still reference this file.          config on all kernel configuration files before rebuilding those
           kernels.
         Solution: "make cleandir && make dependall" in affected  
         directories.  20081205:
           If you build with MKX11=no, you should remove /etc/rc.d/xdm and
 20010803:          /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
         grep.info is now built from grep.texi using makeinfo.  Since it          set and will appear as extra files for MKX11=no update builds.
         requires makeinfo v4.0, you need to install new texinfo before  
         building gnu/usr.bin/grep.  To install new texinfo, please follow  20081122:
         the instruction described in 20010726 entry.          On i386, various kernel options(4) in GENERIC including
           file systems have been disabled and moved into kernel modules.
 20010803:          Before trying a new GENERIC kernel, you have to prepare the
         (i386 only): i386 kernel now uses new instructions like          following files as well as a new GENERIC kernel:
         `fxsave' which old gas doesn't understand.  To build the  
         kernel successfully, you need to build and install a new toolchain,          - build and install kernel modules from src/sys/modules
         (i.e., build.sh -t) or  (temporarily) comment out "options I686_CPU"  
         from your kernel configuration until you rebuild your userland.          - install the latest bootloader, which will load a module
         See 20011029 above and BUILDING file in this directory for more information.            for the file system from which the kernel is loaded automatically
         [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]  
           If you have to load your kernel from a file system which is not of

         Bootloader update on ELF platforms.  DDB in kernels from before          file system module manually on the boot prompt or in the boot.cfg file.
         this will be unable to read symbol tables provided by newer  
         bootloaders.  20080827:
           If you built and installed a libc from sources between
 20010726:          2008/08/20 and 2008/08/26 you got a broken strtouq(3)
         Texinfo was updated to 4.0.  To avoid failures when trying to          which results in false errors reported by lint(1).
         build the included texinfo files, do:          Since this breaks the libc build itself, manual help is
           needed -- lint must be disabled temporarily, e.g.:
         cd src/gnu/usr.bin/texinfo            $ (cd lib/libc && make MKLINT=no dependall install)
         make MKINFO=no dependall install  
   20080813:

         Enabled correct .init/.fini processing in crt0.  The way this          about .go files. You need to remove all .depend files and rebuild.
         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  20080802:
         timestamp on the wrong "dot_init.h").          A regression in binary compatibility for pthread_mutex_t has
           been fixed. Unfortunately, the price is breaking compatibility
         The symptom you will see is that new programs die with SIGSEGV          for -current.
         if you have a stale dependency.  
           Threaded programs (using libpthread) and C++ programs (using
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so          libstdc++) compiled after 20070907 and before 20080802 need to
         before starting your build.          be recompiled.
   
 20010628:          One way to find affected pkgsrc packages:
         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            $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
         bitfield, update your lint(1) before proceeding.            $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
   
 20010226:  20080731:
         Added named user/group to system. Need to hand add this in or builds          WAPBL (metadata journaling support) has been added, but at this
         will break as mtree aborts early.          time isn't backwards compatible with pre-WAPBL aware kernels

   20080531:
         Now a make build should progress.          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed

         Also, PRINTOBJDIR has changed and is now used more heavily.  20071209:
           The acpiec(4) driver has been split into two attachments. If you

         By default, RSA is built into libcrypto.  IDEA and RC5 will not be          configuration file appropriately or see GENERIC for more details.
         built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build  
         additional library libcrypto_{idea,rc5}.  20071028:
           The pccons(4) driver has been removed from the NetBSD/shark port.
           You need to update any custom kernel configuration file you have
           to remove any references to pccons (which includes removing the
           now useless XSERVER option) and replace them with the correct
           entries for the wscons driver.  See the GENERIC configuration file
           for more details.
   
   20070913:
           A latent bug in dhclient/dhcpd that caused it to be unable to
           enumerate interfaces was fixed.  The bug began to cause
           problems after 20070911 when the kernel's SIOCGIFCONF
           implementation was repaired.  From 20070529 to 20070911 racoon
           could not enumerate interfaces.  (These are noted because
           normal kernel/userspace version matching hygiene is not
           sufficient to avoid this problem.)  Ensure that both kernel
           and userland are from after 20070913.
   
   20070703:
           nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
           calls the target-specific strip program, and the logic to pass
           down STRIP from make has been removed.  This requires a
           re-installation of tools.
   
   20070422:
           The way OS emulations lookup filenames inside the emulation root
           has been changed.  Rather than modify the pathname (and copy back
           to userspace) namei() and lookup() directly check the emulation
           root. One side effect is that absolute symlinks inside the emulated
           root file system will be relative to that file system - unless they
           start /../ this is useful when the emulated root is a real install
           that has such links.
           This might affect symlinks that have been added to reference outside
           the emulated root.
   
   20070412:
           The pckbc driver on sgimips IP32 has been removed. Use macekbc
           instead. See the GENERIC32_IP3x kernel configuration for an
           example.
   
   20070319:
           src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
           on many platforms due to incorrect flags settings.  If you
           updated and built after about 20070315, do "nbmake-$arch
           cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
           rebuild of object files that might have been built
           incorrectly, and ensure that you have at least
           src/lib/libc/Makefile 1.130.
   
   20070210:
           src/sys/sys/{sa.h,savar.h} were removed.
             find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
                 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
           will allow dependencies on those files to get get rebuilt
   
   20070209:
           The threading model was changed when the newlock2 branch
           was merged to NetBSD-current.  If you boot with a new
           kernel (version 4.99.10), then you also need a new pthread
           library (/usr/lib/libpthread.so.0.7).  If you boot with
           an old kernel, then you need the old pthread library
           (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
           the pthread library in sync, old threaded applications should
           continue to work with an old or new kernel.  Note that named(8)
           is the only threaded application in the base system.
   
   20061214:
           Following the move of string_to_flags() and flags_to_string()
           from the bin/ls/ sources to libutil, users doing UPDATE builds
           will need to do a "make cleandir" in
                   tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
                   bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
                   usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
                   as the installation images in distrib/
           in order to excise stale references to the old stat_flags.h header
           file in the ls sources -- stat_flags.h has been removed.
   
   20061108:
           The configure script used in the src/tools/gcc compiler has been
           changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
           make clean in src/tools/gcc first to rebuild the compiler.
   
   20061009:
           The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
           available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
   
   20060814:
           The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
           withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
           kernel configuration for an example.  X servers from the last
           few years should cope.
   
   20060703:
           MPACPI is no more. We always configure PCI interrupts using ACPI
           if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
           to ACPI_SCANPCI. Thanks to work from fvdl.
   
   20060627:
           socket(2) has changed, and its system call has been versioned.
           For userlands with the old version of socket(2), make sure that
           your kernel has 'options COMPAT_30' set, or else 'bad system call'
           errors will result.
