 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

 20021130:  20100204:
         fparseln(3) moved from libutil to libc.          The termcap database has been removed from the sources,

         If using build.sh, "cd tools/compat && make clean"  
         before rebuilding the tools.  20091101:
           After updating, it may be necessary to make the 'cleandir'

         The mk.conf(5) variable SYS_INCLUDE has been deprecated,          'build.sh -u tools' or 'build.sh -u distribution'.  Ditto
         including the optional "SYS_INCLUDE=symlinks" support.          src/tools/lex/ and src/usr.bin/lex/.
         All header files, including <sys/*.h> are copied into  
         /usr/include.  20091001:
           On amd64 you must rebuild tools (to get the new binutils)

         split up, with new crti.o and crtn.o files resulting.          An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
         This means that libtool needs to be rebuilt once the          symlink, failing the build.  Delete the link, and the subdir
         new libraries are installed.  The process of rebuilding          it is in, and retry your build.
         libtool will cause it to automatically notice the new  
         required files, but it *must* be rebuilt in order to  20090718:
         do this.          libc build changed so that strchr() provides the extra entry

         their global contructors/destructors will not be invoked.  
 20021121:          Native Xorg was upgraded again.  Builds will probably fail again
         A bug related to how ARM ELF objects were tagged has been          without a clean objdir, at least for src/external/mit/xorg.
         NetBSD ARM ELF uses the soft-VFP floating point model by          Native Xorg was upgraded.  Builds will need a clean objdir for

 20020906:  20081122:
         gehenna-devsw has been merged into the trunk. Need to update and          On i386, various kernel options(4) in GENERIC including
         reinstall usr.sbin/config before build the kernel.          file systems have been disabled and moved into kernel modules.
           Before trying a new GENERIC kernel, you have to prepare the
 20020822:          following files as well as a new GENERIC kernel:
         Crunched rescue tools (contents of /bin and /sbin, plus others)  
         are now provided in /rescue.          - build and install kernel modules from src/sys/modules
         To ensure that these are built statically linked (no matter          - install the latest bootloader, which will load a module
         what the setting of LDSTATIC is), use a crunchgen(1) built            for the file system from which the kernel is loaded automatically
         from sources newer than 20020820 (see the next entry).  
           If you have to load your kernel from a file system which is not of
 20020820:          the same type as the root file system, you have to load the necessary
         crunchgen(1) changed to ensure that the generated program          file system module manually on the boot prompt or in the boot.cfg file.
         is statically linked.  
         Solution: update and reinstall usr.bin/crunch          If you built and installed a libc from sources between
           2008/08/20 and 2008/08/26 you got a broken strtouq(3)
 20020515:          which results in false errors reported by lint(1).
         sshd user/group has been added.  Need to hand add this in, or sshd          Since this breaks the libc build itself, manual help is
         will not let you log in (with default, or UsePrivlegeSeparation=yes)          needed -- lint must be disabled temporarily, e.g.:
             $ (cd lib/libc && make MKLINT=no dependall install)
         Add the following into /etc/group:  
         sshd:*:16:          MKDEBUG build was broken because the .depend files did not know
           about .go files. You need to remove all .depend files and rebuild.
         and the following to /etc/master.passwd (via vipw):  
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin          A regression in binary compatibility for pthread_mutex_t has
           been fixed. Unfortunately, the price is breaking compatibility

         build process).  
           Threaded programs (using libpthread) and C++ programs (using
 20020426:          libstdc++) compiled after 20070907 and before 20080802 need to
         NBUILDJOBS obsoleted in favor of just using -j.          be recompiled.
 20020426:          One way to find affected pkgsrc packages:
         etc/postinstall added, which performs various checks for  
         configuration file updates and changes, and can fix most of            $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
         the problems identified.            $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
         This should make it much easier to upgrade a system's  
         configuration from earlier systems (as far back as NetBSD 1.5).  20080731:
           WAPBL (metadata journaling support) has been added, but at this
 20020320:          time isn't backwards compatible with pre-WAPBL aware kernels
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.          and userland (fsck_ffs in particular).  Please make sure you
         build and install at usr.bin/xinstall before the build.          don't use a journaled filesystem with an older kernel/userland,
           especially an uncleanly mounted journaled filesystem.  WAPBL

         on send(2) operation.  be sure to have sbin/rtsol and usr.sbin/rtsold  
         newer than November 2001 when you upgrade the kernel.  20080721:
           Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
 20020311:          isn't defined.
         ssh configuration files were moved from /etc to /etc/ssh.  Beware  
         if you restart your machine from remote.  Note that sshd.conf needs  20080531:
         to be changed (due to the use of "/etc" inside).          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
           from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
 20020223:          utility needs to be rebuilt and reinstalled as older binaries
         Users of the VAX port will need to rebuild and install gas          won't work correctly. The following sequence of commands:
         so it deal with the now present register prefix used in all  
         the VAX assembly files.            $ (cd sys/sys/ && nbmake-$arch includes)
             $ (cd sbin/drvctl/ && nbmake-$arch clean)
 20020118:            $ (cd sbin/drvctl/ && nbmake-$arch all)
         ntpd user/group has been added.  Need to hand add this in or builds          leaves new drvctl utility in sbin/drvctl build directory.
         will break as mtree aborts early.  
         Add the following into /etc/group:          The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         ntpd:*:15:  20080521:
           For a while, unprivileged UPDATE builds would fail to
         and the following to /etc/master.passwd (via vipw):          succeed at the checkflist stage, complaining that
           ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
           If you already hit this problem, update the .mk file,
 20011207:          remove ${DESTDIR}/stand/<arch>, and re-run the build.
         If you're attempting to build a snapshot on sparc64 and are getting  20080303:
         reloc errors from the toolchain groff binary this means your native          Linker warnings are now fatal if $WARNS>0.
         toolchain has some broken C++ bits.  
         To fix:          The posix_fadvise system call has been changed from an assembly
           stub, to a c file that calls an assembly stub. You need to
         Build a new toolchain (i.e. build.sh -t)          'rm -f posix_fadvise.* .depend' in the libc build directory to
         Use the new toolchain to build and install natively (i.e. /usr/lib)          avoid using the old assembly stub.
         gnu/lib/libgcc  20071209:
         gnu/lib/libstdc++          The acpiec(4) driver has been split into two attachments. If you
           get ACPI errors before the attachment, please update your kernel
         After this a snapshot will be able to be built.          configuration file appropriately or see GENERIC for more details.
 20011201:  20071115:
         In order for a sparc64 build to work you must have a working awk. If          The it(4) driver has been renamed to itesio(4) and the old port
         you've built and installed a system with the new toolchain up to this          argument specified in the kernel configuration file is not valid
         point you do not have a working awk as its ability to do floating          anymore. The itesio(4) driver now uses the Super I/O address port
         point is broken.          rather than the EC address port. Please update your kernel
           configuration file appropriately or see GENERIC for more details.
         To build:  
         remake and install gnu/lib/libgcc          The pccons(4) driver has been removed from the NetBSD/shark port.

         to build a new kernel.          enumerate interfaces was fixed.  The bug began to cause
           problems after 20070911 when the kernel's SIOCGIFCONF
 20011030:          implementation was repaired.  From 20070529 to 20070911 racoon
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)          could not enumerate interfaces.  (These are noted because
