 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.

 20010922:  20090530:
         The new toolchain is enabled on i386.  This new build method          pkg_install now depends on the pkgdb cache for automatic conflict
         is intended to make all the upgrade issues elsewhere in UPDATING          detection.  It is recommented to rebuild the cache with
         obsolete (stay tuned...).          ``pkg_admin rebuild''.
   
         i386 platform builds must now set TOOLDIR in mk.conf or the          audit-packages.conf(5) has been superseded by pkg_install.conf(5).

         where host build tools will be installed, and must NOT be          been retired.  The functionality of audit-packages(1) and
         the same as src/tools.          download-vulnerability-list(1) has moved into pkg_admin(1), wrapper
           scripts that handle the common use cases are provided.
         (Optionally, USETOOLS=no can be set in the environment if you  
         wish to avoid using the separate host toolchain for building a  20081205:
         subtree.  Otherwise, this will default to "yes" automatically.)          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
 20010915:          set and will appear as extra files for MKX11=no update builds.
         The new "ubcperf" code committed by Chuck Silvers removed  
         a header file, uvm/uvm_vnode.h.  There may be stale .depend  20080827:
         files that still reference this file.          If you built and installed a libc from sources between
           2008/08/20 and 2008/08/26 you got a broken strtouq(3)

         directories.          Since this breaks the libc build itself, manual help is
           needed -- lint must be disabled temporarily, e.g:
 20010803:            $ (cd lib/libc && make MKLINT=no dependall install)
         grep.info is now built from grep.texi using makeinfo.  Since it  
         requires makeinfo v4.0, you need to install new texinfo before  20080813:
         building gnu/usr.bin/grep.  To install new texinfo, please follow          MKDEBUG build was broken because the .depend files did not know
         the instruction described in 20010726 entry.          about .go files. You need to remove all .depend files and rebuild.
   
 20010803:  20080731:
         (i386 only): i386 kernel now uses new instructions like fxsave which          WAPBL (metadata journaling support) has been added, but at this
         old gas doesn't understand.  To build the kernel successfuly, you          time isn't backwards compatible with pre-WAPBL aware kernels
         need to build and install new gas (gnu/usr.bin/gas.new).          and userland (fsck_ffs in particular).  Please make sure you
           don't use a journaled filesystem with an older kernel/userland,
 20010731:          especially an uncleanly mounted journaled filesystem.  WAPBL
         Bootloader update on ELF platforms.  DDB in kernels from before          also requires the super block to be in the UFS2 format.  You

         bootloaders.  
   20080721:
 20010726:          Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
         Texinfo was updated to 4.0.  To avoid failures when trying to          isn't defined.
         build the included texinfo files, do:  
   20080531:
         cd src/gnu/usr.bin/texinfo          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
         make MKINFO=no dependall install          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
           utility needs to be rebuilt and reinstalled as older binaries
 20010718:          won't work correctly. The following sequence of commands:
   
         Enabled correct .init/.fini processing in crt0.  The way this            $ (cd sys/sys/ && nbmake-$arch includes)
         was done was to change a -I directive to cc(1), which means            $ (cd sbin/drvctl/ && nbmake-$arch clean)
         make(1) will have a stale dependency (it will be checking the            $ (cd sbin/drvctl/ && nbmake-$arch all)
         timestamp on the wrong "dot_init.h").  
           leaves new drvctl utility in sbin/drvctl build directory.
         The symptom you will see is that new programs die with SIGSEGV  
         if you have a stale dependency.  20080503:
           The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so  
         before starting your build.  20080521:
           For a while, unprivileged UPDATE builds would fail to
 20010628:          succeed at the checkflist stage, complaining that
           ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
         A construct was added to uvm_page.h that uncovered a bug          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
         in lint(1).  If you get a warning/error about a non-portable          If you already hit this problem, update the .mk file,
         bitfield, update your lint(1) before proceeding.          remove ${DESTDIR}/stand/<arch>, and re-run the build.
   
 20010226:  20080303:
           Linker warnings are now fatal if $WARNS>0.
         Added named user/group to system. Need to hand add this in or builds  
         will break as mtree aborts early.  20080126:
           The posix_fadvise system call has been changed from an assembly
         To work around add by hand:          stub, to a c file that calls an assembly stub. You need to
           'rm -f posix_fadvise.* .depend' in the libc build directory to
         named:*:14:          avoid using the old assembly stub.
   
         to /etc/group and add:  20071209:
           The acpiec(4) driver has been split into two attachments. If you
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin          get ACPI errors before the attachment, please update your kernel
           configuration file appropriately or see GENERIC for more details.
         to master.passwd (use vipw for instance if doing by hand).  
   20071115:
         Now a make build should progress.          The it(4) driver has been renamed to itesio(4) and the old port
           argument specified in the kernel configuration file is not valid
 20010219:          anymore. The itesio(4) driver now uses the Super I/O address port
         get/setprogname() added. Any hostprog's that may use this will need          rather than the EC address port. Please update your kernel
         to be bootstrapped manually until the host system is current.          configuration file appropriately or see GENERIC for more details.
   
         Known problems: sys/arch/macppc/stand/fixcoff  20071028:
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to          The pccons(4) driver has been removed from the NetBSD/shark port.
                           CFLAGS and rebuilding should work)          You need to update any custom kernel configuration file you have
                         usr.sbin/mdsetimage - Build a static copy if          to remove any references to pccons (which includes removing the
                           building a snapshot before fully bootstrapped.          now useless XSERVER option) and replace them with the correct
           entries for the wscons driver.  See the GENERIC configuration file

         prepare the code to compile with stricter gcc flags. in  
         particular start eliminating redundant declarations. Yacc  20070913:
         needs to be installed before make build.          A latent bug in dhclient/dhcpd that caused it to be unable to
           enumerate interfaces was fixed.  The bug began to cause
 20010114:          problems after 20070911 when the kernel's SIOCGIFCONF
         introduce .if commands(target) in make(1). You need to          implementation was repaired.  From 20070529 to 20070911 racoon
         bring everything up-to-date first, then without installing          could not enumerate interfaces.  (These are noted because
         anything make and install in usr.bin/make, then proceed          normal kernel/userspace version matching hygiene is not
         with make build.          sufficient to avoid this problem.)  Ensure that both kernel
           and userland are from after 20070913.
 20010101:  
         bsd.subdir.mk committed 20001230 had a bug which caused  20070703:
         afterinstall targets to run too soon; update again.          nbinstall has been renamed as it calls the target specific and
           the logic to pass down STRIP from mk been removed.  This forces
 20001230:          a re-installation of tools.
         New share/mk files needed to support .WAIT in SUBDIR variables.  
         If you get make errors,  20070422:
                 (cd share/mk; make install)          The way OS emulations lookup filenames inside the emulation root
         Also, PRINTOBJDIR has changed and is now used more heavily.          has been changed.  Rather than modify the pathname (and copy back
           to userspace) namei() and lookup() directly check the emulation
 20001019:          root. One side effect is that absolute symlinks inside the emulated
         The `ca' device driver has been replaced by `ld'; although the          root file system will be relative to that file system - unless they
         major and minor numbers haven't changed, you should update your /dev          start /../ this is useful when the emulated root is a real install
         directory.          that has such links.
           This might affect symlinks that have been added to reference outside
 20000929:          the emulated root.
         The following make directives are obsoleted.  
         MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA  20070412:
         By default, RSA is built into libcrypto.  IDEA and RC5 will not be          The pckbc driver on sgimips IP32 has been removed. Use macekbc
         built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build          instead. See the GENERIC32_IP3x kernel configuration for an
         additional library libcrypto_{idea,rc5}.          example.
   
 20000623:  20070319:
         MKCRYPTO and friends added to share/mk/bsd.own.mk.          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
         'cd share/mk ; make install' needed before make build.          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.
