 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.

 ^^^^^^^^^^^^^^^  ^^^^^^^^^^^^^^^
 20020906:  20090110:
         gehenna-devsw has been merged into the trunk. Need to update and          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
         reinstall usr.sbin/config before build the kernel.          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
 20020822:             before installing.
         Crunched rescue tools (contents of /bin and /sbin, plus others)          3. If you don't use build.sh and you build directly to root, and
         are now provided in /rescue.             your build breaks in the middle, don't despair. Make sure headers
              are installed properly, and start building libraries first libc
         To ensure that these are built statically linked (no matter             and libutil, install them and then continue building all the
         what the setting of LDSTATIC is), use a crunchgen(1) built             libraries in src/lib and src/gnu/lib and install them. Once
         from sources newer than 20020820 (see the next entry).             the new libraries are installed, you can restart the build.
           4. If you compile packages and you notice link time warnings,
 20020820:             you'll need to bump them and rebuild them.
         crunchgen(1) changed to ensure that the generated program          5. Next time you run pwd_mkdb with the new binary, the file
         is statically linked.             will be upgraded and it will not be backwards compatible.
           6. The utmpx/wtmpx files have been versioned, and there is
         Solution: update and reinstall usr.bin/crunch             a heuristic for utmp. You are better off removing the
              old files after upgrading.
         sshd user/group has been added.  Need to hand add this in, or sshd  20081219:
         will not let you log in (with default, or UsePrivlegeSeparation=yes)          config(1) has been updated, and one of the files it creates -
           swapnetbsd.o - has changed format.  You need to rebuild config
         Add the following into /etc/group:          (done automatically by build.sh) and then you need to rerun
           config on all kernel configuration files before rebuilding those
         sshd:*:16:          kernels.
         and the following to /etc/master.passwd (via vipw):  20081205:
           If you build with MKX11=no, you should remove /etc/rc.d/xdm and
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin          /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
           set and will appear as extra files for MKX11=no update builds.
         also /var/chroot/sshd directory needs to be present (digged as a part of  
         build process).  20081122:
           On i386, various kernel options(4) in GENERIC including
 20020426:          file systems have been disabled and moved into kernel modules.
         NBUILDJOBS obsoleted in favor of just using -j.          Before trying a new GENERIC kernel, you have to prepare the
           following files as well as a new GENERIC kernel:
         etc/postinstall added, which performs various checks for          - build and install kernel modules from src/sys/modules
         configuration file updates and changes, and can fix most of  
         the problems identified.          - install the latest bootloader, which will load a module
         This should make it much easier to upgrade a system's            for the file system from which the kernel is loaded automatically
         configuration from earlier systems (as far back as NetBSD 1.5).  
           If you have to load your kernel from a file system which is not of
 20020320:          the same type as the root file system, you have to load the necessary
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.          file system module manually on the boot prompt or in the boot.cfg file.
         build and install at usr.bin/xinstall before the build.  
 20020319:          If you built and installed a libc from sources between
         raw IPv6 socket now makes strict checking for sa_family and sa_len          2008/08/20 and 2008/08/26 you got a broken strtouq(3)
         on send(2) operation.  be sure to have sbin/rtsol and usr.sbin/rtsold          which results in false errors reported by lint(1).
         newer than November 2001 when you upgrade the kernel.          Since this breaks the libc build itself, manual help is
           needed -- lint must be disabled temporarily, e.g.:
 20020311:            $ (cd lib/libc && make MKLINT=no dependall install)
         ssh configuration files were moved from /etc to /etc/ssh.  Beware  
         if you restart your machine from remote.  Note that sshd.conf needs  20080813:
         to be changed (due to the use of "/etc" inside).          MKDEBUG build was broken because the .depend files did not know
           about .go files. You need to remove all .depend files and rebuild.
         Users of the VAX port will need to rebuild and install gas  20080731:
         so it deal with the now present register prefix used in all          WAPBL (metadata journaling support) has been added, but at this
         the VAX assembly files.          time isn't backwards compatible with pre-WAPBL aware kernels
           and userland (fsck_ffs in particular).  Please make sure you
 20020118:          don't use a journaled filesystem with an older kernel/userland,
           especially an uncleanly mounted journaled filesystem.  WAPBL
         ntpd user/group has been added.  Need to hand add this in or builds          also requires the super block to be in the UFS2 format.  You
         will break as mtree aborts early.          can use fsck_ffs -c 4 to update the superblock format.
         Add the following into /etc/group:  20080721:
           Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
         ntpd:*:15:          isn't defined.
         and the following to /etc/master.passwd (via vipw):  20080531:
           The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
           utility needs to be rebuilt and reinstalled as older binaries
 20011207:          won't work correctly. The following sequence of commands:
         If you're attempting to build a snapshot on sparc64 and are getting            $ (cd sys/sys/ && nbmake-$arch includes)
         reloc errors from the toolchain groff binary this means your native            $ (cd sbin/drvctl/ && nbmake-$arch clean)
         toolchain has some broken C++ bits.            $ (cd sbin/drvctl/ && nbmake-$arch all)
         To fix:          leaves new drvctl utility in sbin/drvctl build directory.
         Build a new toolchain (i.e. build.sh -t)  20080503:
         Use the new toolchain to build and install natively (i.e. /usr/lib)          The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         gnu/lib/libgcc  20080521:
         gnu/lib/libstdc++          For a while, unprivileged UPDATE builds would fail to
           succeed at the checkflist stage, complaining that
         After this a snapshot will be able to be built.          ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
           problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
 20011201:          If you already hit this problem, update the .mk file,
         In order for a sparc64 build to work you must have a working awk. If          remove ${DESTDIR}/stand/<arch>, and re-run the build.
         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  20080303:
         point is broken.          Linker warnings are now fatal if $WARNS>0.
         To build:  20080126:
           The posix_fadvise system call has been changed from an assembly
         remake and install gnu/lib/libgcc          stub, to a c file that calls an assembly stub. You need to
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links          'rm -f posix_fadvise.* .depend' in the libc build directory to
         against the new libgcc.a)          avoid using the old assembly stub.
 20011128:  20071209:
         Kernel config information was changed to use defflag in          The acpiec(4) driver has been split into two attachments. If you
         the various "files" files.  Bug fixes to config(8) are          get ACPI errors before the attachment, please update your kernel
         required in order for this to work properly.  Make sure          configuration file appropriately or see GENERIC for more details.
         to build and install in usr.sbin/config before attempting  
         to build a new kernel.  20071115:
           The it(4) driver has been renamed to itesio(4) and the old port
 20011030:          argument specified in the kernel configuration file is not valid
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)          anymore. The itesio(4) driver now uses the Super I/O address port
         before building libc.          rather than the EC address port. Please update your kernel
           configuration file appropriately or see GENERIC for more details.
         The new document BUILDING.mdoc (view with nroff | more, or  20071028:
         see pre-generated .txt and .html versions) describes the build          The pccons(4) driver has been removed from the NetBSD/shark port.
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN          You need to update any custom kernel configuration file you have
         build process, are intended in the long run to replace this          to remove any references to pccons (which includes removing the
         manual update log.          now useless XSERVER option) and replace them with the correct
           entries for the wscons driver.  See the GENERIC configuration file
         Users building a USE_NEW_TOOLCHAIN system should read the          for more details.
         BUILDING document for caveats.  Generally, BUILDING supersedes  
         UPDATING for these systems, as tool updating is taken care of  20070913:
         by the new build system.          A latent bug in dhclient/dhcpd that caused it to be unable to
           enumerate interfaces was fixed.  The bug began to cause
 20011028:          problems after 20070911 when the kernel's SIOCGIFCONF
         src/etc/Makefile now needs install to be able to handle          implementation was repaired.  From 20070529 to 20070911 racoon
         symlinks that point to nowhere. A bug in install that          could not enumerate interfaces.  (These are noted because
         prevented this was corrected.          normal kernel/userspace version matching hygiene is not
           sufficient to avoid this problem.)  Ensure that both kernel
         Solution: update and reinstall usr.bin/xinstall          and userland are from after 20070913.
         Better Solution: Use the new toolchain and it will just work  
         for you.  20070703:
           nbinstall has been renamed as it calls the target specific and
 20011006:          the logic to pass down STRIP from mk been removed.  This forces
         /etc/mtree/NetBSD.dist has been updated to take advantage of          a re-installation of tools.
         absolute path support added to mtree(8). Older mtree(8)s don't  
         understand the format.  20070422:
           The way OS emulations lookup filenames inside the emulation root
         Solution: update and reinstall usr.sbin/mtree          has been changed.  Rather than modify the pathname (and copy back
           to userspace) namei() and lookup() directly check the emulation
 20011004:          root. One side effect is that absolute symlinks inside the emulated
         Crunchgen has been updated to work via reach-over makefiles. Updating          root file system will be relative to that file system - unless they
         is suggested before running a snapshot build          start /../ this is useful when the emulated root is a real install
           that has such links.
 20010915:          This might affect symlinks that have been added to reference outside
         The new "ubcperf" code committed by Chuck Silvers removed          the emulated root.
         a header file, uvm/uvm_vnode.h.  There may be stale .depend  
         files that still reference this file.  20070412:
           The pckbc driver on sgimips IP32 has been removed. Use macekbc
         Solution: "make cleandir && make dependall" in affected          instead. See the GENERIC32_IP3x kernel configuration for an
         directories.          example.
 20010803:  20070319:
         grep.info is now built from grep.texi using makeinfo.  Since it          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
         requires makeinfo v4.0, you need to install new texinfo before          on many platforms due to incorrect flags settings.  If you
         building gnu/usr.bin/grep.  To install new texinfo, please follow          updated and built after about 20070315, do "nbmake-$arch
         the instruction described in 20010726 entry.          cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
           rebuild of object files that might have been built
 20010803:          incorrectly, and ensure that you have at least
         (i386 only): i386 kernel now uses new instructions like          src/lib/libc/Makefile 1.130.
         `fxsave' which old gas doesn't understand.  To build the  
         kernel successfully, you need to build and install a new toolchain,  20070210:
         (i.e., build.sh -t) or  (temporarily) comment out "options I686_CPU"          src/sys/sys/{sa.h,savar.h} were removed.
         from your kernel configuration until you rebuild your userland.            find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
         See 20011029 above and BUILDING file in this directory for more information.                | xargs egrep -l '/sa.h|/savar.h' | xargs rm
         [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]          will allow dependencies on those files to get get rebuilt
 20010731:  20070209:
         Bootloader update on ELF platforms.  DDB in kernels from before          The threading model was changed when the newlock2 branch
         this will be unable to read symbol tables provided by newer          was merged to NetBSD-current.  If you boot with a new
         bootloaders.          kernel (version 4.99.10), then you also need a new pthread
           library (/usr/lib/libpthread.so.0.7).  If you boot with
 20010726:          an old kernel, then you need the old pthread library
         Texinfo was updated to 4.0.  To avoid failures when trying to          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         build the included texinfo files, do:          the pthread library in sync, old threaded applications should
           continue to work with an old or new kernel.  Note that named(8)
         cd src/gnu/usr.bin/texinfo          is the only threaded application in the base system.
         make MKINFO=no dependall install  
 20010718:          Following the move of string_to_flags() and flags_to_string()
         Enabled correct .init/.fini processing in crt0.  The way this          from the bin/ls/ sources to libutil, users doing UPDATE builds
         was done was to change a -I directive to cc(1), which means          will need to do a "make cleandir" in
         make(1) will have a stale dependency (it will be checking the                  tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
         timestamp on the wrong "dot_init.h").                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
                   usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         The symptom you will see is that new programs die with SIGSEGV                  as the installation images in distrib/
         if you have a stale dependency.          in order to excise stale references to the old stat_flags.h header
           file in the ls sources -- stat_flags.h has been removed.
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so  
         before starting your build.  20061108:
           The configure script used in the src/tools/gcc compiler has been
 20010628:          changed to indicate that our libc has ssp support built-in and
         A construct was added to uvm_page.h that uncovered a bug          does not depend on -lssp and -lssp-nonshared. You'll need to
         in lint(1).  If you get a warning/error about a non-portable          make clean in src/tools/gcc first to rebuild the compiler.
         bitfield, update your lint(1) before proceeding.  
 20010226:          The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
         Added named user/group to system. Need to hand add this in or builds          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
         will break as mtree aborts early.  
         To work around add by hand:          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
           withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         named:*:14:          kernel configuration for an example.  X servers from the last
           few years should cope.
         to /etc/group and add:  
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin          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 master.passwd (use vipw for instance if doing by hand).          to ACPI_SCANPCI. Thanks to work from fvdl.
         Now a make build should progress.  20060627:
           socket(2) has changed, and its system call has been versioned.
 20010219:          For userlands with the old version of socket(2), make sure that
         get/setprogname() added. Any hostprogs that may use this will need          your kernel has 'options COMPAT_30' set, or else 'bad system call'
         to be bootstrapped manually until the host system is current.          errors will result.
         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.  
         prepare the code to compile with stricter gcc flags. in  
         particular start eliminating redundant declarations. Yacc  
         needs to be installed before make build.  
         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.  
         bsd.subdir.mk committed 20001230 had a bug which caused  
         afterinstall targets to run too soon; update again.  
         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.  
         The `ca' device driver has been replaced by `ld'; although the  
         major and minor numbers haven't changed, you should update your /dev  
         The following make directives are obsoleted.  
         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}.
