 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.

 20020515:  20090110:
         sshd user/group has been added.  Need to hand add this in, or sshd          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
         will not let you log in (with default, or UsePrivlegeSeparation=yes)          1. Make sure your kernel has COMPAT_50 in it. Build and install.
           2. make sure build.sh completes and the binaries in a chroot work
         Add the following into /etc/group:             before installing.
           3. If you don't use build.sh and you build directly to root, and
         sshd:*:16:             your build breaks in the middle, don't despair. Make sure headers
              are installed properly, and start building libraries first libc
         and the following to /etc/master.passwd (via vipw):             and libutil, install them and then continue building all the
              libraries in src/lib and src/gnu/lib and install them. Once
         sshd:*:16:16::0:0:sshd privsep:/var/empty:/sbin/nologin             the new libraries are installed, you can restart the build.
           4. If you compile packages and you notice link time warnings,
         also /var/empty directory needs to be present (digged as a part of             you'll need to bump them and rebuild them.
         build process).          5. Next time you run pwd_mkdb with the new binary, the file
              will be upgraded and it will not be backwards compatible.
 20020426:          6. The utmpx/wtmpx files have been versioned, and there is
         NBUILDJOBS obsoleted in favor of just using -j.             a heuristic for utmp. You are better off removing the
              old files after upgrading.
         etc/postinstall added, which performs various checks for  20081219:
         configuration file updates and changes, and can fix most of          config(1) has been updated, and one of the files it creates -
         the problems identified.          swapnetbsd.o - has changed format.  You need to rebuild config
         This should make it much easier to upgrade a system's          (done automatically by build.sh) and then you need to rerun
         configuration from earlier systems (as far back as NetBSD 1.5).          config on all kernel configuration files before rebuilding those
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.  20081205:
         build and install at usr.bin/xinstall before the build.          If you build with MKX11=no, you should remove /etc/rc.d/xdm and
           /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
 20020319:          set and will appear as extra files for MKX11=no update builds.
         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  20081122:
         newer than November 2001 when you upgrade the kernel.          On i386, various kernel options(4) in GENERIC including
           file systems have been disabled and moved into kernel modules.
 20020311:          Before trying a new GENERIC kernel, you have to prepare the
         ssh configuration files were moved from /etc to /etc/ssh.  Beware          following files as well as a new GENERIC kernel:
         if you restart your machine from remote.  Note that sshd.conf needs  
         to be changed (due to the use of "/etc" inside).          - build and install kernel modules from src/sys/modules
 20020223:          - install the latest bootloader, which will load a module
         Users of the VAX port will need to rebuild and install gas            for the file system from which the kernel is loaded automatically
         so it deal with the now present register prefix used in all  
         the VAX assembly files.          If you have to load your kernel from a file system which is not of
           the same type as the root file system, you have to load the necessary
 20020118:          file system module manually on the boot prompt or in the boot.cfg file.
         ntpd user/group has been added.  Need to hand add this in or builds  20080827:
         will break as mtree aborts early.          If you built and installed a libc from sources between
           2008/08/20 and 2008/08/26 you got a broken strtouq(3)
         Add the following into /etc/group:          which results in false errors reported by lint(1).
           Since this breaks the libc build itself, manual help is
         ntpd:*:15:          needed -- lint must be disabled temporarily, e.g.:
             $ (cd lib/libc && make MKLINT=no dependall install)
         and the following to /etc/master.passwd (via vipw):  
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin          MKDEBUG build was broken because the .depend files did not know
           about .go files. You need to remove all .depend files and rebuild.
         If you're attempting to build a snapshot on sparc64 and are getting          WAPBL (metadata journaling support) has been added, but at this
         reloc errors from the toolchain groff binary this means your native          time isn't backwards compatible with pre-WAPBL aware kernels
         toolchain has some broken C++ bits.          and userland (fsck_ffs in particular).  Please make sure you
           don't use a journaled filesystem with an older kernel/userland,
         To fix:          especially an uncleanly mounted journaled filesystem.  WAPBL
           also requires the super block to be in the UFS2 format.  You
         Build a new toolchain (i.e. build.sh -t)          can use fsck_ffs -c 4 to update the superblock format.
         Use the new toolchain to build and install natively (i.e. /usr/lib)  
         gnu/lib/libgcc          Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
         gnu/lib/libstdc++          isn't defined.
         After this a snapshot will be able to be built.  20080531:
           The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
 20011201:          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
         In order for a sparc64 build to work you must have a working awk. If          utility needs to be rebuilt and reinstalled as older binaries
         you've built and installed a system with the new toolchain up to this          won't work correctly. The following sequence of commands:
         point you do not have a working awk as its ability to do floating  
         point is broken.            $ (cd sys/sys/ && nbmake-$arch includes)
             $ (cd sbin/drvctl/ && nbmake-$arch clean)
         To build:            $ (cd sbin/drvctl/ && nbmake-$arch all)
         remake and install gnu/lib/libgcc          leaves new drvctl utility in sbin/drvctl build directory.
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links  
         against the new libgcc.a)  20080503:
           The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         Kernel config information was changed to use defflag in  20080521:
         the various "files" files.  Bug fixes to config(8) are          For a while, unprivileged UPDATE builds would fail to

         to build and install in usr.sbin/config before attempting          ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
         to build a new kernel.          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
           If you already hit this problem, update the .mk file,
 20011030:          remove ${DESTDIR}/stand/<arch>, and re-run the build.
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)  
         before building libc.  20080303:
           Linker warnings are now fatal if $WARNS>0.
         The new document BUILDING.mdoc (view with nroff | more, or  20080126:
         see pre-generated .txt and .html versions) describes the build          The posix_fadvise system call has been changed from an assembly
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN          stub, to a c file that calls an assembly stub. You need to
         build process, are intended in the long run to replace this          'rm -f posix_fadvise.* .depend' in the libc build directory to
         manual update log.          avoid using the old assembly stub.
         Users building a USE_NEW_TOOLCHAIN system should read the  20071209:
         BUILDING document for caveats.  Generally, BUILDING supersedes          The acpiec(4) driver has been split into two attachments. If you
         UPDATING for these systems, as tool updating is taken care of          get ACPI errors before the attachment, please update your kernel
         by the new build system.          configuration file appropriately or see GENERIC for more details.
 20011028:  20071115:
         src/etc/Makefile now needs install to be able to handle          The it(4) driver has been renamed to itesio(4) and the old port
         symlinks that point to nowhere. A bug in install that          argument specified in the kernel configuration file is not valid
         prevented this was corrected.          anymore. The itesio(4) driver now uses the Super I/O address port
           rather than the EC address port. Please update your kernel
         Solution: update and reinstall usr.bin/xinstall          configuration file appropriately or see GENERIC for more details.
         Better Solution: Use the new toolchain and it will just work  
         for you.  20071028:
           The pccons(4) driver has been removed from the NetBSD/shark port.
 20011006:          You need to update any custom kernel configuration file you have
         /etc/mtree/NetBSD.dist has been updated to take advantage of          to remove any references to pccons (which includes removing the
         absolute path support added to mtree(8). Older mtree(8)s don't          now useless XSERVER option) and replace them with the correct
         understand the format.          entries for the wscons driver.  See the GENERIC configuration file
           for more details.
         Solution: update and reinstall usr.sbin/mtree  
 20011004:          A latent bug in dhclient/dhcpd that caused it to be unable to
         Crunchgen has been updated to work via reach-over makefiles. Updating          enumerate interfaces was fixed.  The bug began to cause
         is suggested before running a snapshot build          problems after 20070911 when the kernel's SIOCGIFCONF
           implementation was repaired.  From 20070529 to 20070911 racoon
 20010915:          could not enumerate interfaces.  (These are noted because
         The new "ubcperf" code committed by Chuck Silvers removed          normal kernel/userspace version matching hygiene is not
         a header file, uvm/uvm_vnode.h.  There may be stale .depend          sufficient to avoid this problem.)  Ensure that both kernel
         files that still reference this file.          and userland are from after 20070913.
         Solution: "make cleandir && make dependall" in affected  20070703:
         directories.          nbinstall has been renamed as it calls the target specific and
           the logic to pass down STRIP from mk been removed.  This forces
 20010803:          a re-installation of tools.
         grep.info is now built from grep.texi using makeinfo.  Since it  
         requires makeinfo v4.0, you need to install new texinfo before  20070422:
         building gnu/usr.bin/grep.  To install new texinfo, please follow          The way OS emulations lookup filenames inside the emulation root
         the instruction described in 20010726 entry.          has been changed.  Rather than modify the pathname (and copy back
           to userspace) namei() and lookup() directly check the emulation
 20010803:          root. One side effect is that absolute symlinks inside the emulated
         (i386 only): i386 kernel now uses new instructions like          root file system will be relative to that file system - unless they
         `fxsave' which old gas doesn't understand.  To build the          start /../ this is useful when the emulated root is a real install
         kernel successfully, you need to build and install new gas          that has such links.
         (gnu/usr.bin/gas.new), or (temporarily) comment out          This might affect symlinks that have been added to reference outside
         "options I686_CPU" from your kernel configuration until you          the emulated root.
         rebuilt your userland (and got a new gas).  
 20010731:          The pckbc driver on sgimips IP32 has been removed. Use macekbc

         this will be unable to read symbol tables provided by newer          example.
 20010726:          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
         Texinfo was updated to 4.0.  To avoid failures when trying to          on many platforms due to incorrect flags settings.  If you
         build the included texinfo files, do:          updated and built after about 20070315, do "nbmake-$arch
           cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
         cd src/gnu/usr.bin/texinfo          rebuild of object files that might have been built
         make MKINFO=no dependall install          incorrectly, and ensure that you have at least
           src/lib/libc/Makefile 1.130.
         Enabled correct .init/.fini processing in crt0.  The way this  20070210:
         was done was to change a -I directive to cc(1), which means          src/sys/sys/{sa.h,savar.h} were removed.
         make(1) will have a stale dependency (it will be checking the            find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
         timestamp on the wrong "dot_init.h").                | xargs egrep -l '/sa.h|/savar.h' | xargs rm
           will allow dependencies on those files to get get rebuilt
         The symptom you will see is that new programs die with SIGSEGV  
         if you have a stale dependency.  20070209:
           The threading model was changed when the newlock2 branch
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so          was merged to NetBSD-current.  If you boot with a new
         before starting your build.          kernel (version 4.99.10), then you also need a new pthread
           library (/usr/lib/libpthread.so.0.7).  If you boot with
 20010628:          an old kernel, then you need the old pthread library
         A construct was added to uvm_page.h that uncovered a bug          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         in lint(1).  If you get a warning/error about a non-portable          the pthread library in sync, old threaded applications should
         bitfield, update your lint(1) before proceeding.          continue to work with an old or new kernel.  Note that named(8)
           is the only threaded application in the base system.
         Added named user/group to system. Need to hand add this in or builds  20061214:
         will break as mtree aborts early.          Following the move of string_to_flags() and flags_to_string()
           from the bin/ls/ sources to libutil, users doing UPDATE builds
         To work around add by hand:          will need to do a "make cleandir" in

                   usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         to /etc/group and add:                  as the installation images in distrib/

         Known problems: sys/arch/macppc/stand/fixcoff          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to  
                           CFLAGS and rebuilding should work)  20060814:
