 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

 20020320:  20090126:
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.          The __posix_fadvise50 system call changed assembly stub type. You need to
         build and install at usr.bin/xinstall before the build.          'rm -f __posix_fadvise50.*' in the libc build directory to avoid using
           the old assembly stub.
 20020319:  
         raw IPv6 socket now makes strict checking for sa_family and sa_len  20090202:
         on send(2) operation.  be sure to have sbin/rtsol and usr.sbin/rtsold          pkg_install now depends on the pkgdb cache for automatic conflict
         newer than November 2001 when you upgrade the kernel.          detection.  It is recommented to rebuild the cache with
           ``pkg_admin rebuild''.
 20020311:  
         ssh configuration files were moved from /etc to /etc/ssh.  Beware  20090110:
         if you restart your machine from remote.  Note that sshd.conf needs          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
         to be changed (due to the use of "/etc" inside).          1. Make sure your kernel has COMPAT_50 in it. Build and install.
              This is needed even in the MODULAR kernel because there is
 20020223:             conditionally compiled code in rtsock.c.
         Users of the VAX port will need to rebuild and install gas          2. make sure build.sh completes and the binaries in a chroot work
         so it deal with the now present register prefix used in all             before installing.
         the VAX assembly files.          3. If you don't use build.sh and you build directly to root, and
              your build breaks in the middle, don't despair. Make sure headers

              and libutil, install them and then continue building all the
         ntpd user/group has been added.  Need to hand add this in or builds             libraries in src/lib and src/gnu/lib and install them. Once
         will break as mtree aborts early.             the new libraries are installed, you can restart the build.
           4. If you compile packages and you notice link time warnings,
         Add the following into /etc/group:             rebuild the required packages to update their shared libraries.
              Any package you rebuild will require rebuilding all the packages
         ntpd:*:15:             that depend on it.
           5. Next time you run pwd_mkdb with the new binary, the file
         and the following to /etc/master.passwd (via vipw):             will be upgraded and it will not be backwards compatible.
           6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin             lastlogx(5)) have been versioned, and there is a heuristic
              for utmp. You are better off removing the old files after
 20011207:             upgrading.  The automated clearing of /var/run during
              boot, and the automated rotating of files in /var/log by
         If you're attempting to build a snapshot on sparc64 and are getting             newsyslog(8), may mean that you do not have to remove the
         reloc errors from the toolchain groff binary this means your native             files manually.
         toolchain has some broken C++ bits.          7. The optional accounting file (/var/account/acct, see
              accton(8)) has not been versioned, and will need to be
         To fix:             removed.  The automatic rotation of the accounting file by
              /etc/daily limits the bad consequences of failure to remove
         Build a new toolchain (i.e. build.sh -t)             the file.
         Use the new toolchain to build and install natively (i.e. /usr/lib)  
   20081219:
         gnu/lib/libgcc          config(1) has been updated, and one of the files it creates -
         gnu/lib/libstdc++          swapnetbsd.o - has changed format.  You need to rebuild config
           (done automatically by build.sh) and then you need to rerun
         After this a snapshot will be able to be built.          config on all kernel configuration files before rebuilding those
           kernels.
 20011201:  
         In order for a sparc64 build to work you must have a working awk. If  20081205:
         you've built and installed a system with the new toolchain up to this          If you build with MKX11=no, you should remove /etc/rc.d/xdm and
         point you do not have a working awk as its ability to do floating          /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
         point is broken.          set and will appear as extra files for MKX11=no update builds.
   
         To build:  20081122:
           On i386, various kernel options(4) in GENERIC including
         remake and install gnu/lib/libgcc          file systems have been disabled and moved into kernel modules.
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links          Before trying a new GENERIC kernel, you have to prepare the
         against the new libgcc.a)          following files as well as a new GENERIC kernel:
   
 20011128:          - build and install kernel modules from src/sys/modules
         Kernel config information was changed to use defflag in  
         the various "files" files.  Bug fixes to config(8) are          - install the latest bootloader, which will load a module
         required in order for this to work properly.  Make sure            for the file system from which the kernel is loaded automatically
         to build and install in usr.sbin/config before attempting  
         to build a new kernel.          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
 20011030:          file system module manually on the boot prompt or in the boot.cfg file.
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)  
         before building libc.  20080827:
           If you built and installed a libc from sources between
 20011029:          2008/08/20 and 2008/08/26 you got a broken strtouq(3)
         The new document BUILDING.mdoc (view with nroff | more, or          which results in false errors reported by lint(1).
         see pre-generated .txt and .html versions) describes the build          Since this breaks the libc build itself, manual help is
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN          needed -- lint must be disabled temporarily, e.g.:
         build process, are intended in the long run to replace this            $ (cd lib/libc && make MKLINT=no dependall install)
         manual update log.  
   20080813:
         Users building a USE_NEW_TOOLCHAIN system should read the          MKDEBUG build was broken because the .depend files did not know
         BUILDING document for caveats.  Generally, BUILDING supersedes          about .go files. You need to remove all .depend files and rebuild.
         UPDATING for these systems, as tool updating is taken care of  
         by the new build system.  20080731:
           WAPBL (metadata journaling support) has been added, but at this
 20011028:          time isn't backwards compatible with pre-WAPBL aware kernels
         src/etc/Makefile now needs install to be able to handle          and userland (fsck_ffs in particular).  Please make sure you
         symlinks that point to nowhere. A bug in install that          don't use a journaled filesystem with an older kernel/userland,
         prevented this was corrected.          especially an uncleanly mounted journaled filesystem.  WAPBL
           also requires the super block to be in the UFS2 format.  You
         Solution: update and reinstall usr.bin/xinstall          can use fsck_ffs -c 4 to update the superblock format.
         Better Solution: Use the new toolchain and it will just work  
         for you.  20080721:
           Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
 20011006:          isn't defined.
         /etc/mtree/NetBSD.dist has been updated to take advantage of  
         absolute path support added to mtree(8). Older mtree(8)s don't  20080531:
         understand the format.          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
           from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
         Solution: update and reinstall usr.sbin/mtree          utility needs to be rebuilt and reinstalled as older binaries
           won't work correctly. The following sequence of commands:
 20011004:  
         Crunchgen has been updated to work via reach-over makefiles. Updating            $ (cd sys/sys/ && nbmake-$arch includes)
         is suggested before running a snapshot build            $ (cd sbin/drvctl/ && nbmake-$arch clean)
             $ (cd sbin/drvctl/ && nbmake-$arch all)
 20010915:  
         The new "ubcperf" code committed by Chuck Silvers removed          leaves new drvctl utility in sbin/drvctl build directory.
         a header file, uvm/uvm_vnode.h.  There may be stale .depend  
         files that still reference this file.  20080503:
           The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         Solution: "make cleandir && make dependall" in affected  
         directories.  20080521:
           For a while, unprivileged UPDATE builds would fail to
 20010803:          succeed at the checkflist stage, complaining that
         grep.info is now built from grep.texi using makeinfo.  Since it          ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
         requires makeinfo v4.0, you need to install new texinfo before          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
         building gnu/usr.bin/grep.  To install new texinfo, please follow          If you already hit this problem, update the .mk file,
         the instruction described in 20010726 entry.          remove ${DESTDIR}/stand/<arch>, and re-run the build.
   
 20010803:  20080303:
         (i386 only): i386 kernel now uses new instructions like          Linker warnings are now fatal if $WARNS>0.
         `fxsave' which old gas doesn't understand.  To build the  
         kernel successfully, you need to build and install new gas  20080126:
         (gnu/usr.bin/gas.new), or (temporarily) comment out          The posix_fadvise system call has been changed from an assembly
         "options I686_CPU" from your kernel configuration until you          stub, to a c file that calls an assembly stub. You need to
         rebuilt your userland (and got a new gas).          'rm -f posix_fadvise.* .depend' in the libc build directory to
           avoid using the old assembly stub.
 20010731:  
         Bootloader update on ELF platforms.  DDB in kernels from before  20071209:
         this will be unable to read symbol tables provided by newer          The acpiec(4) driver has been split into two attachments. If you
         bootloaders.          get ACPI errors before the attachment, please update your kernel
           configuration file appropriately or see GENERIC for more details.
 20010726:  
         Texinfo was updated to 4.0.  To avoid failures when trying to  20071115:
         build the included texinfo files, do:          The it(4) driver has been renamed to itesio(4) and the old port
           argument specified in the kernel configuration file is not valid
         cd src/gnu/usr.bin/texinfo          anymore. The itesio(4) driver now uses the Super I/O address port
         make MKINFO=no dependall install          rather than the EC address port. Please update your kernel
           configuration file appropriately or see GENERIC for more details.
 20010718:  
         Enabled correct .init/.fini processing in crt0.  The way this  20071028:
         was done was to change a -I directive to cc(1), which means          The pccons(4) driver has been removed from the NetBSD/shark port.

         timestamp on the wrong "dot_init.h").          to remove any references to pccons (which includes removing the
           now useless XSERVER option) and replace them with the correct
         The symptom you will see is that new programs die with SIGSEGV          entries for the wscons driver.  See the GENERIC configuration file
         if you have a stale dependency.          for more details.
   
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so  20070913:
         before starting your build.          A latent bug in dhclient/dhcpd that caused it to be unable to
           enumerate interfaces was fixed.  The bug began to cause
 20010628:          problems after 20070911 when the kernel's SIOCGIFCONF
         A construct was added to uvm_page.h that uncovered a bug          implementation was repaired.  From 20070529 to 20070911 racoon
         in lint(1).  If you get a warning/error about a non-portable          could not enumerate interfaces.  (These are noted because
         bitfield, update your lint(1) before proceeding.          normal kernel/userspace version matching hygiene is not
           sufficient to avoid this problem.)  Ensure that both kernel
 20010226:          and userland are from after 20070913.
         Added named user/group to system. Need to hand add this in or builds  
         will break as mtree aborts early.  20070703:
           nbinstall has been renamed as it calls the target specific and
         To work around add by hand:          the logic to pass down STRIP from mk been removed.  This forces
           a re-installation of tools.

   20070422:
         to /etc/group and add:          The way OS emulations lookup filenames inside the emulation root
           has been changed.  Rather than modify the pathname (and copy back
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin          to userspace) namei() and lookup() directly check the emulation
           root. One side effect is that absolute symlinks inside the emulated
         to master.passwd (use vipw for instance if doing by hand).          root file system will be relative to that file system - unless they
           start /../ this is useful when the emulated root is a real install
         Now a make build should progress.          that has such links.
           This might affect symlinks that have been added to reference outside
 20010219:          the emulated root.
         get/setprogname() added. Any hostprogs that may use this will need  
         to be bootstrapped manually until the host system is current.  20070412:
           The pckbc driver on sgimips IP32 has been removed. Use macekbc
         Known problems: sys/arch/macppc/stand/fixcoff          instead. See the GENERIC32_IP3x kernel configuration for an
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to          example.
                           CFLAGS and rebuilding should work)  
                         usr.sbin/mdsetimage - Build a static copy if  20070319:
                           building a snapshot before fully bootstrapped.          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
           on many platforms due to incorrect flags settings.  If you
 20010204:          updated and built after about 20070315, do "nbmake-$arch
         prepare the code to compile with stricter gcc flags. in          cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
         particular start eliminating redundant declarations. Yacc          rebuild of object files that might have been built
         needs to be installed before make build.          incorrectly, and ensure that you have at least
           src/lib/libc/Makefile 1.130.
 20010114:  
         introduce .if commands(target) in make(1). You need to  20070210:
         bring everything up-to-date first, then without installing          src/sys/sys/{sa.h,savar.h} were removed.
         anything make and install in usr.bin/make, then proceed            find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
         with make build.                | xargs egrep -l '/sa.h|/savar.h' | xargs rm
           will allow dependencies on those files to get get rebuilt
 20010101:  
         bsd.subdir.mk committed 20001230 had a bug which caused  20070209:
         afterinstall targets to run too soon; update again.          The threading model was changed when the newlock2 branch
           was merged to NetBSD-current.  If you boot with a new
 20001230:          kernel (version 4.99.10), then you also need a new pthread
         New share/mk files needed to support .WAIT in SUBDIR variables.          library (/usr/lib/libpthread.so.0.7).  If you boot with
         If you get make errors,          an old kernel, then you need the old pthread library
                 (cd share/mk; make install)          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         Also, PRINTOBJDIR has changed and is now used more heavily.          the pthread library in sync, old threaded applications should
           continue to work with an old or new kernel.  Note that named(8)
 20001019:          is the only threaded application in the base system.
         The `ca' device driver has been replaced by `ld'; although the  
         major and minor numbers haven't changed, you should update your /dev  20061214:
         directory.          Following the move of string_to_flags() and flags_to_string()
           from the bin/ls/ sources to libutil, users doing UPDATE builds
 20000929:          will need to do a "make cleandir" in
         The following make directives are obsoleted.                  tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,

         By default, RSA is built into libcrypto.  IDEA and RC5 will not be                  usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build                  as the installation images in distrib/
         additional library libcrypto_{idea,rc5}.          in order to excise stale references to the old stat_flags.h header
           file in the ls sources -- stat_flags.h has been removed.
   
   20061108:
           The configure script used in the src/tools/gcc compiler has been
           changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
           make clean in src/tools/gcc first to rebuild the compiler.
   
   20061009:
           The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
           available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
   
   20060814:
           The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
           withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
           kernel configuration for an example.  X servers from the last
           few years should cope.
   
   20060703:
           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 ACPI_SCANPCI. Thanks to work from fvdl.
   
   20060627:
           socket(2) has changed, and its system call has been versioned.
           For userlands with the old version of socket(2), make sure that
           your kernel has 'options COMPAT_30' set, or else 'bad system call'
           errors will result.
