 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:  20090530:
         sshd user/group has been added.  Need to hand add this in, or sshd          pkg_install now depends on the pkgdb cache for automatic conflict
         will not let you log in (with default, or UsePrivlegeSeparation=yes)          detection.  It is recommented to rebuild the cache with
           ``pkg_admin rebuild''.
         Add the following into /etc/group:  
           audit-packages.conf(5) has been superseded by pkg_install.conf(5).
         sshd:*:16:          The default configuration is the same.  Support for pkg_view(1) has
           been retired.  The functionality of audit-packages(1) and
         and the following to /etc/master.passwd (via vipw):          download-vulnerability-list(1) has moved into pkg_admin(1), wrapper
           scripts that handle the common use cases are provided.
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin  
   20081205:

         build process).          /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.
 20020426:  
         NBUILDJOBS obsoleted in favor of just using -j.  20080827:
           If you built and installed a libc from sources between
 20020426:          2008/08/20 and 2008/08/26 you got a broken strtouq(3)
         etc/postinstall added, which performs various checks for          which results in false errors reported by lint(1).
         configuration file updates and changes, and can fix most of          Since this breaks the libc build itself, manual help is
         the problems identified.          needed -- lint must be disabled temporarily, e.g:
         This should make it much easier to upgrade a system's            $ (cd lib/libc && make MKLINT=no dependall install)
         configuration from earlier systems (as far back as NetBSD 1.5).  
   20080813:
 20020320:          MKDEBUG build was broken because the .depend files did not know
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.          about .go files. You need to remove all .depend files and rebuild.
         build and install at usr.bin/xinstall before the build.  
   20080731:
 20020319:          WAPBL (metadata journaling support) has been added, but at this
         raw IPv6 socket now makes strict checking for sa_family and sa_len          time isn't backwards compatible with pre-WAPBL aware kernels
         on send(2) operation.  be sure to have sbin/rtsol and usr.sbin/rtsold          and userland (fsck_ffs in particular).  Please make sure you
         newer than November 2001 when you upgrade the kernel.          don't use a journaled filesystem with an older kernel/userland,
           especially an uncleanly mounted journaled filesystem.  WAPBL
 20020311:          also requires the super block to be in the UFS2 format.  You
         ssh configuration files were moved from /etc to /etc/ssh.  Beware          can use fsck_ffs -c 4 to update the superblock format.
         if you restart your machine from remote.  Note that sshd.conf needs  
         to be changed (due to the use of "/etc" inside).  20080721:
           Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
 20020223:          isn't defined.
         Users of the VAX port will need to rebuild and install gas  
         so it deal with the now present register prefix used in all  20080531:
         the VAX assembly files.          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
           from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
 20020118:          utility needs to be rebuilt and reinstalled as older binaries
           won't work correctly. The following sequence of commands:
         ntpd user/group has been added.  Need to hand add this in or builds  
         will break as mtree aborts early.            $ (cd sys/sys/ && nbmake-$arch includes)
             $ (cd sbin/drvctl/ && nbmake-$arch clean)
         Add the following into /etc/group:            $ (cd sbin/drvctl/ && nbmake-$arch all)
   
         ntpd:*:15:          leaves new drvctl utility in sbin/drvctl build directory.
   
         and the following to /etc/master.passwd (via vipw):  20080503:
           The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin  
   20080521:

         reloc errors from the toolchain groff binary this means your native          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
         toolchain has some broken C++ bits.          If you already hit this problem, update the .mk file,
           remove ${DESTDIR}/stand/<arch>, and re-run the build.
         To fix:  
   20080303:
         Build a new toolchain (i.e. build.sh -t)          Linker warnings are now fatal if $WARNS>0.
         Use the new toolchain to build and install natively (i.e. /usr/lib)  
   20080126:
         gnu/lib/libgcc          The posix_fadvise system call has been changed from an assembly
         gnu/lib/libstdc++          stub, to a c file that calls an assembly stub. You need to
           'rm -f posix_fadvise.* .depend' in the libc build directory to
         After this a snapshot will be able to be built.          avoid using the old assembly stub.
   
 20011201:  20071209:
         In order for a sparc64 build to work you must have a working awk. If          The acpiec(4) driver has been split into two attachments. If you

         point is broken.  
   20071115:
         To build:          The it(4) driver has been renamed to itesio(4) and the old port
           argument specified in the kernel configuration file is not valid
         remake and install gnu/lib/libgcc          anymore. The itesio(4) driver now uses the Super I/O address port

           for more details.
 20011030:  
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)  20070913:
         before building libc.          A latent bug in dhclient/dhcpd that caused it to be unable to
           enumerate interfaces was fixed.  The bug began to cause
 20011029:          problems after 20070911 when the kernel's SIOCGIFCONF
         The new document BUILDING.mdoc (view with nroff | more, or          implementation was repaired.  From 20070529 to 20070911 racoon

         Users building a USE_NEW_TOOLCHAIN system should read the  20070703:

         by the new build system.          a re-installation of tools.
   
 20011028:  20070422:
         src/etc/Makefile now needs install to be able to handle          The way OS emulations lookup filenames inside the emulation root
         symlinks that point to nowhere. A bug in install that          has been changed.  Rather than modify the pathname (and copy back
         prevented this was corrected.          to userspace) namei() and lookup() directly check the emulation

           This might affect symlinks that have been added to reference outside
 20011006:          the emulated root.
         /etc/mtree/NetBSD.dist has been updated to take advantage of  
         absolute path support added to mtree(8). Older mtree(8)s don't  20070412:
         understand the format.          The pckbc driver on sgimips IP32 has been removed. Use macekbc
           instead. See the GENERIC32_IP3x kernel configuration for an
         Solution: update and reinstall usr.sbin/mtree          example.
   
 20011004:  20070319:
         Crunchgen has been updated to work via reach-over makefiles. Updating          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
         is suggested before running a snapshot build          on many platforms due to incorrect flags settings.  If you

         grep.info is now built from grep.texi using makeinfo.  Since it          will allow dependencies on those files to get get rebuilt
         requires makeinfo v4.0, you need to install new texinfo before  
         building gnu/usr.bin/grep.  To install new texinfo, please follow  20070209:
         the instruction described in 20010726 entry.          The threading model was changed when the newlock2 branch
           was merged to NetBSD-current.  If you boot with a new
 20010803:          kernel (version 4.99.10), then you also need a new pthread
         (i386 only): i386 kernel now uses new instructions like          library (/usr/lib/libpthread.so.0.7).  If you boot with
         `fxsave' which old gas doesn't understand.  To build the          an old kernel, then you need the old pthread library
         kernel successfully, you need to build and install new gas          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and

         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so  20060814:
         before starting your build.          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been

         in lint(1).  If you get a warning/error about a non-portable  
         bitfield, update your lint(1) before proceeding.  20060703:
           MPACPI is no more. We always configure PCI interrupts using ACPI
 20010226:          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
         Added named user/group to system. Need to hand add this in or builds          to ACPI_SCANPCI. Thanks to work from fvdl.
         will break as mtree aborts early.  
   20060627:
         To work around add by hand:          socket(2) has changed, and its system call has been versioned.
           For userlands with the old version of socket(2), make sure that
         named:*:14:          your kernel has 'options COMPAT_30' set, or else 'bad system call'
           errors will result.
         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

 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}.
