 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.

 ^^^^^^^^^^^^^^^  ^^^^^^^^^^^^^^^
   
 20021010:  20081219:
         The config(8) grammar was changed to allow options to register          config(1) has been updated, and one of the files it creates -
         dependencies on attributes, as well as other options.  Users          swapnetbsd.o - has changed format.  You need to rebuild config
         must update and reinstall usr.sbin/config before building a new          (done automatically by build.sh) and then you need to rerun
         kernel.          config on all kernel configuration files before rebuilding those
           kernels.
 20021009:  
         A new attribute dependency syntax was introduced to config(8),  20081205:
         which is now used by the SCSI configuration description.  Users          If you build with MKX11=no, you should remove /etc/rc.d/xdm and
         must update and reinstall usr.sbin/config before building a new          /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
         kernel.          set and will appear as extra files for MKX11=no update builds.
   
 20021003:  20081122:
         Several changes have been made to the autoconfiguration          On i386, various kernel options(4) in GENERIC including
         framework.  Users must update and reinstall usr.sbin/config          file systems have been disabled and moved into kernel modules.
         before building a new kernel.          Before trying a new GENERIC kernel, you have to prepare the
           following files as well as a new GENERIC kernel:
 20020922:  
         MKDYNAMICROOT=yes enabled by default, which means that          - build and install kernel modules from src/sys/modules
         certain shared libraries are installed into /lib, the shared  
         linker is installed into /libexec, and all programs in /bin          - install the latest bootloader, which will load a module
         and /sbin are dynamically linked.            for the file system from which the kernel is loaded automatically
         If you do not use "make build", you should ensure that  
         you have the libraries and shared linker in the new locations,          If you have to load your kernel from a file system which is not of
         with:          the same type as the root file system, you have to load the necessary
                 make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so          file system module manually on the boot prompt or in the boot.cfg file.
   
 20020917:  20080827:
         USE_NEW_TOOLCHAIN has been replaced with:          If you built and installed a libc from sources between
             -   TOOLCHAIN_MISSING -- set to "yes" on platforms for which          2008/08/20 and 2008/08/26 you got a broken strtouq(3)
                 there is no working in-tree toolchain (hppa, ns32k, sh5,          which results in false errors reported by lint(1).
                 x86_64).          Since this breaks the libc build itself, manual help is
             -   EXTERNAL_TOOLCHAIN -- if defined by the user, points to the          needed -- lint must be disabled temporarily, e.g.:
                 root ofan external toolchain (e.g. /usr/local/gnu).  This            $ (cd lib/libc && make MKLINT=no dependall install)
                 enables the cross-build framework even for TOOLCHAIN_MISSING  
                 platforms.  20080813:
           MKDEBUG build was broken because the .depend files did not know
 20020906:          about .go files. You need to remove all .depend files and rebuild.
         gehenna-devsw has been merged into the trunk. Need to update and  
         reinstall usr.sbin/config before build the kernel.  20080731:
           WAPBL (metadata journaling support) has been added, but at this
 20020822:          time isn't backwards compatible with pre-WAPBL aware kernels
         Crunched rescue tools (contents of /bin and /sbin, plus others)          and userland (fsck_ffs in particular).  Please make sure you
         are now provided in /rescue.          don't use a journaled filesystem with an older kernel/userland,
           especially an uncleanly mounted journaled filesystem.  WAPBL
         To ensure that these are built statically linked (no matter          also requires the super block to be in the UFS2 format.  You
         what the setting of LDSTATIC is), use a crunchgen(1) built          can use fsck_ffs -c 4 to update the superblock format.
         from sources newer than 20020820 (see the next entry).  
   20080721:
 20020820:          Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
         crunchgen(1) changed to ensure that the generated program          isn't defined.
         is statically linked.  
   20080531:
         Solution: update and reinstall usr.bin/crunch          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
           from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
 20020515:          utility needs to be rebuilt and reinstalled as older binaries
         sshd user/group has been added.  Need to hand add this in, or sshd          won't work correctly. The following sequence of commands:
         will not let you log in (with default, or UsePrivlegeSeparation=yes)  
             $ (cd sys/sys/ && nbmake-$arch includes)
         Add the following into /etc/group:            $ (cd sbin/drvctl/ && nbmake-$arch clean)
             $ (cd sbin/drvctl/ && nbmake-$arch all)
         sshd:*:16:  
           leaves new drvctl utility in sbin/drvctl build directory.
         and the following to /etc/master.passwd (via vipw):  
   20080503:
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin          The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
   
         also /var/chroot/sshd directory needs to be present (digged as a part of  20080521:
         build process).          For a while, unprivileged UPDATE builds would fail to
           succeed at the checkflist stage, complaining that
 20020426:          ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
         NBUILDJOBS obsoleted in favor of just using -j.          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
           If you already hit this problem, update the .mk file,
 20020426:          remove ${DESTDIR}/stand/<arch>, and re-run the build.
         etc/postinstall added, which performs various checks for  
         configuration file updates and changes, and can fix most of  20080303:
         the problems identified.          Linker warnings are now fatal if $WARNS>0.
         This should make it much easier to upgrade a system's  
         configuration from earlier systems (as far back as NetBSD 1.5).  20080126:
           The posix_fadvise system call has been changed from an assembly
 20020320:          stub, to a c file that calls an assembly stub. You need to
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.          'rm -f posix_fadvise.* .depend' in the libc build directory to
         build and install at usr.bin/xinstall before the build.          avoid using the old assembly stub.
   
 20020319:  20071209:
         raw IPv6 socket now makes strict checking for sa_family and sa_len          The acpiec(4) driver has been split into two attachments. If you
         on send(2) operation.  be sure to have sbin/rtsol and usr.sbin/rtsold          get ACPI errors before the attachment, please update your kernel
         newer than November 2001 when you upgrade the kernel.          configuration file appropriately or see GENERIC for more details.
   
 20020311:  20071115:
         ssh configuration files were moved from /etc to /etc/ssh.  Beware          The it(4) driver has been renamed to itesio(4) and the old port
         if you restart your machine from remote.  Note that sshd.conf needs          argument specified in the kernel configuration file is not valid
         to be changed (due to the use of "/etc" inside).          anymore. The itesio(4) driver now uses the Super I/O address port
           rather than the EC address port. Please update your kernel
 20020223:          configuration file appropriately or see GENERIC for more details.
         Users of the VAX port will need to rebuild and install gas  
         so it deal with the now present register prefix used in all  20071028:
         the VAX assembly files.          The pccons(4) driver has been removed from the NetBSD/shark port.
           You need to update any custom kernel configuration file you have
 20020118:          to remove any references to pccons (which includes removing the
           now useless XSERVER option) and replace them with the correct
         ntpd user/group has been added.  Need to hand add this in or builds          entries for the wscons driver.  See the GENERIC configuration file
         will break as mtree aborts early.          for more details.
   
         Add the following into /etc/group:  20070913:
           A latent bug in dhclient/dhcpd that caused it to be unable to
         ntpd:*:15:          enumerate interfaces was fixed.  The bug began to cause
           problems after 20070911 when the kernel's SIOCGIFCONF
         and the following to /etc/master.passwd (via vipw):          implementation was repaired.  From 20070529 to 20070911 racoon
           could not enumerate interfaces.  (These are noted because
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin          normal kernel/userspace version matching hygiene is not
           sufficient to avoid this problem.)  Ensure that both kernel
 20011207:          and userland are from after 20070913.
   
         If you're attempting to build a snapshot on sparc64 and are getting  20070703:
         reloc errors from the toolchain groff binary this means your native          nbinstall has been renamed as it calls the target specific and
         toolchain has some broken C++ bits.          the logic to pass down STRIP from mk been removed.  This forces
           a re-installation of tools.
         To fix:  
   20070422:
         Build a new toolchain (i.e. build.sh -t)          The way OS emulations lookup filenames inside the emulation root
         Use the new toolchain to build and install natively (i.e. /usr/lib)          has been changed.  Rather than modify the pathname (and copy back
           to userspace) namei() and lookup() directly check the emulation
         gnu/lib/libgcc          root. One side effect is that absolute symlinks inside the emulated
         gnu/lib/libstdc++          root file system will be relative to that file system - unless they
           start /../ this is useful when the emulated root is a real install
         After this a snapshot will be able to be built.          that has such links.
           This might affect symlinks that have been added to reference outside
 20011201:          the emulated root.
         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  20070412:
         point you do not have a working awk as its ability to do floating          The pckbc driver on sgimips IP32 has been removed. Use macekbc
         point is broken.          instead. See the GENERIC32_IP3x kernel configuration for an
           example.
         To build:  
   20070319:
         remake and install gnu/lib/libgcc          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links          on many platforms due to incorrect flags settings.  If you
         against the new libgcc.a)          updated and built after about 20070315, do "nbmake-$arch
           cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
 20011128:          rebuild of object files that might have been built
         Kernel config information was changed to use defflag in          incorrectly, and ensure that you have at least
         the various "files" files.  Bug fixes to config(8) are          src/lib/libc/Makefile 1.130.
         required in order for this to work properly.  Make sure  
         to build and install in usr.sbin/config before attempting  20070210:
         to build a new kernel.          src/sys/sys/{sa.h,savar.h} were removed.
             find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
 20011030:                | xargs egrep -l '/sa.h|/savar.h' | xargs rm
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)          will allow dependencies on those files to get get rebuilt
         before building libc.  
   20070209:
 20011029:          The threading model was changed when the newlock2 branch
         The new document BUILDING.mdoc (view with nroff | more, or          was merged to NetBSD-current.  If you boot with a new
         see pre-generated .txt and .html versions) describes the build          kernel (version 4.99.10), then you also need a new pthread
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN          library (/usr/lib/libpthread.so.0.7).  If you boot with
         build process, are intended in the long run to replace this          an old kernel, then you need the old pthread library
         manual update log.          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
           the pthread library in sync, old threaded applications should
         Users building a USE_NEW_TOOLCHAIN system should read the          continue to work with an old or new kernel.  Note that named(8)
         BUILDING document for caveats.  Generally, BUILDING supersedes          is the only threaded application in the base system.
         UPDATING for these systems, as tool updating is taken care of  
         by the new build system.  20061214:
           Following the move of string_to_flags() and flags_to_string()
 20011028:          from the bin/ls/ sources to libutil, users doing UPDATE builds
         src/etc/Makefile now needs install to be able to handle          will need to do a "make cleandir" in
         symlinks that point to nowhere. A bug in install that                  tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
         prevented this was corrected.                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
                   usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         Solution: update and reinstall usr.bin/xinstall                  as the installation images in distrib/
         Better Solution: Use the new toolchain and it will just work          in order to excise stale references to the old stat_flags.h header
         for you.          file in the ls sources -- stat_flags.h has been removed.
   
 20011006:  20061108:
         /etc/mtree/NetBSD.dist has been updated to take advantage of          The configure script used in the src/tools/gcc compiler has been
         absolute path support added to mtree(8). Older mtree(8)s don't          changed to indicate that our libc has ssp support built-in and
         understand the format.          does not depend on -lssp and -lssp-nonshared. You'll need to
           make clean in src/tools/gcc first to rebuild the compiler.
         Solution: update and reinstall usr.sbin/mtree  
   20061009:
 20011004:          The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
         Crunchgen has been updated to work via reach-over makefiles. Updating          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
         is suggested before running a snapshot build  
   20060814:
 20010915:          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
         The new "ubcperf" code committed by Chuck Silvers removed          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         a header file, uvm/uvm_vnode.h.  There may be stale .depend          kernel configuration for an example.  X servers from the last
         files that still reference this file.          few years should cope.
   
         Solution: "make cleandir && make dependall" in affected  20060703:
         directories.          MPACPI is no more. We always configure PCI interrupts using ACPI
           if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
 20010803:          to ACPI_SCANPCI. Thanks to work from fvdl.
         grep.info is now built from grep.texi using makeinfo.  Since it  
         requires makeinfo v4.0, you need to install new texinfo before  20060627:
         building gnu/usr.bin/grep.  To install new texinfo, please follow          socket(2) has changed, and its system call has been versioned.
         the instruction described in 20010726 entry.          For userlands with the old version of socket(2), make sure that
           your kernel has 'options COMPAT_30' set, or else 'bad system call'
 20010803:          errors will result.
         (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}.
