 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.

 Recent changes:  Recent changes:
 ^^^^^^^^^^^^^^^  ^^^^^^^^^^^^^^^
   
 20001019:  20090110:
         The `ca' device driver has been replaced by `lsu'; although the          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
         major and minor numbers haven't changed, you should update your /dev          1. Make sure your kernel has COMPAT_50 in it. Build and install.
         directory.          2. make sure build.sh completes and the binaries in a chroot work
              before installing.
 20000929:          3. If you don't use build.sh and you build directly to root, and
         The following make directives are obsoleted.             your build breaks in the middle, don't despair. Make sure headers
         MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA             are installed properly, and start building libraries first libc
         By default, RSA is built into libcrypto.  IDEA and RC5 will not be             and libutil, install them and then continue building all the
         bulit into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build             libraries in src/lib and src/gnu/lib and install them. Once
         additional library libcrypto_{idea,rc5}.             the new libraries are installed, you can restart the build.
           4. If you compile packages and you notice link time warnings,
 20000623:             you'll need to bump them and rebuild them.
         MKCRYPTO and friends added to share/mk/bsd.own.mk.          5. Next time you run pwd_mkdb with the new binary, the file
         'cd share/mk ; make install' needed before make build.             will be upgraded and it will not be backwards compatible.
           6. The utmpx/wtmpx files have been versioned, and there is
              a heuristic for utmp. You are better off removing the
              old files after upgrading.
   
   20081219:
           config(1) has been updated, and one of the files it creates -
           swapnetbsd.o - has changed format.  You need to rebuild config
           (done automatically by build.sh) and then you need to rerun
           config on all kernel configuration files before rebuilding those
           kernels.
   
   20081205:
           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
           set and will appear as extra files for MKX11=no update builds.
   
   20081122:
           On i386, various kernel options(4) in GENERIC including
           file systems have been disabled and moved into kernel modules.
           Before trying a new GENERIC kernel, you have to prepare the
           following files as well as a new GENERIC kernel:
   
           - build and install kernel modules from src/sys/modules
   
           - install the latest bootloader, which will load a module
             for the file system from which the kernel is loaded automatically
   
           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
           file system module manually on the boot prompt or in the boot.cfg file.
   
   20080827:
           If you built and installed a libc from sources between
           2008/08/20 and 2008/08/26 you got a broken strtouq(3)
           which results in false errors reported by lint(1).
           Since this breaks the libc build itself, manual help is
           needed -- lint must be disabled temporarily, e.g.:
             $ (cd lib/libc && make MKLINT=no dependall install)
   
   20080813:
           MKDEBUG build was broken because the .depend files did not know
           about .go files. You need to remove all .depend files and rebuild.
   
   20080731:
           WAPBL (metadata journaling support) has been added, but at this
           time isn't backwards compatible with pre-WAPBL aware kernels
           and userland (fsck_ffs in particular).  Please make sure you
           don't use a journaled filesystem with an older kernel/userland,
           especially an uncleanly mounted journaled filesystem.  WAPBL
           also requires the super block to be in the UFS2 format.  You
           can use fsck_ffs -c 4 to update the superblock format.
   
   20080721:
           Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
           isn't defined.
   
   20080531:
           The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
           from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
           utility needs to be rebuilt and reinstalled as older binaries
           won't work correctly. The following sequence of commands:
   
             $ (cd sys/sys/ && nbmake-$arch includes)
             $ (cd sbin/drvctl/ && nbmake-$arch clean)
             $ (cd sbin/drvctl/ && nbmake-$arch all)
   
           leaves new drvctl utility in sbin/drvctl build directory.
   
   20080503:
           The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
   
   20080521:
           For a while, unprivileged UPDATE builds would fail to
           succeed at the checkflist stage, complaining that
           ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
           problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
           If you already hit this problem, update the .mk file,
           remove ${DESTDIR}/stand/<arch>, and re-run the build.
   
   20080303:
           Linker warnings are now fatal if $WARNS>0.
   
   20080126:
           The posix_fadvise system call has been changed from an assembly
           stub, to a c file that calls an assembly stub. You need to
           'rm -f posix_fadvise.* .depend' in the libc build directory to
           avoid using the old assembly stub.
   
   20071209:
           The acpiec(4) driver has been split into two attachments. If you
           get ACPI errors before the attachment, please update your kernel
           configuration file appropriately or see GENERIC for more details.
   
   20071115:
           The it(4) driver has been renamed to itesio(4) and the old port
           argument specified in the kernel configuration file is not valid
           anymore. The itesio(4) driver now uses the Super I/O address port
           rather than the EC address port. Please update your kernel
           configuration file appropriately or see GENERIC for more details.
   
   20071028:
           The pccons(4) driver has been removed from the NetBSD/shark port.
           You need to update any custom kernel configuration file you have
           to remove any references to pccons (which includes removing the
           now useless XSERVER option) and replace them with the correct
           entries for the wscons driver.  See the GENERIC configuration file
           for more details.
   
   20070913:
           A latent bug in dhclient/dhcpd that caused it to be unable to
           enumerate interfaces was fixed.  The bug began to cause
           problems after 20070911 when the kernel's SIOCGIFCONF
           implementation was repaired.  From 20070529 to 20070911 racoon
           could not enumerate interfaces.  (These are noted because
           normal kernel/userspace version matching hygiene is not
           sufficient to avoid this problem.)  Ensure that both kernel
           and userland are from after 20070913.
   
   20070703:
           nbinstall has been renamed as it calls the target specific and
           the logic to pass down STRIP from mk been removed.  This forces
           a re-installation of tools.
   
   20070422:
           The way OS emulations lookup filenames inside the emulation root
           has been changed.  Rather than modify the pathname (and copy back
           to userspace) namei() and lookup() directly check the emulation
           root. One side effect is that absolute symlinks inside the emulated
           root file system will be relative to that file system - unless they
           start /../ this is useful when the emulated root is a real install
           that has such links.
           This might affect symlinks that have been added to reference outside
           the emulated root.
   
   20070412:
           The pckbc driver on sgimips IP32 has been removed. Use macekbc
           instead. See the GENERIC32_IP3x kernel configuration for an
           example.
   
   20070319:
           src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
           on many platforms due to incorrect flags settings.  If you
           updated and built after about 20070315, do "nbmake-$arch
           cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
           rebuild of object files that might have been built
           incorrectly, and ensure that you have at least
           src/lib/libc/Makefile 1.130.
   
   20070210:
           src/sys/sys/{sa.h,savar.h} were removed.
             find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
                 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
           will allow dependencies on those files to get get rebuilt
   
   20070209:
           The threading model was changed when the newlock2 branch
           was merged to NetBSD-current.  If you boot with a new
           kernel (version 4.99.10), then you also need a new pthread
           library (/usr/lib/libpthread.so.0.7).  If you boot with
           an old kernel, then you need the old pthread library
           (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
           the pthread library in sync, old threaded applications should
           continue to work with an old or new kernel.  Note that named(8)
           is the only threaded application in the base system.
   
   20061214:
           Following the move of string_to_flags() and flags_to_string()
           from the bin/ls/ sources to libutil, users doing UPDATE builds
           will need to do a "make cleandir" in
                   tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
                   bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
                   usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
                   as the installation images in distrib/
           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.
