 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.

   20110117:
 20030117:          Assembler files on the following platforms no longer use -tradition-cpp:
         Texinfo was updated to 4.3.  To avoid failures when trying to          - Alpha,
         build the included texinfo files, do:          - AMD64,
           - i386,
         cd src/gnu/usr.bin/texinfo          - SPARC,
         make MKINFO=no dependall install          - SPARC64.
           This can break the build of individual parts of the tree.  This is

         The METALOG format changed slightly, to remove the leading          /usr/share/mk and re-run config(1) for any kernel configurations as
         "${DESTDIR}" from path names.          needed.
         This only affects people building with UNPRIVED.  
         For complete safety, remove the DESTDIR entirely and  20101217:
         update tools/mtree, before running make build.          The tcpdump(8) program was changed to drop privileges and chroot(2)
           by default. It may be necessary to manually update passwd(5) and

         reinstall usr.bin/xinstall first.          so building gcc will end up printing:
               checking dependency style of gcc... none
 20021130:              configure: error: no usable dependency style found
         fparseln(3) moved from libutil to libc.          Fix it by rebuilding and re-installing env.
         If building to DESTDIR=/, reinstall the includes

         before rebuilding the tools.          versions between xorg-server and drivers.
   
 20021126:  20100604:
         The mk.conf(5) variable SYS_INCLUDE has been deprecated,          The update of ATF to 0.9 causes old tests written in shell to fail
         including the optional "SYS_INCLUDE=symlinks" support.          unless they are rebuilt.  If you are building with MKUPDATE=yes,

         /usr/include.          trees by hand.
   
 20021121:  20100522:
         The C run-time support files crtbegin.o and crtend.o          Recent Xorg updates in xsrc/external/mit/ will cause various build
         (and their companions crtbeginS.o and crtendS.o) were          problems.  Delete your entire DESTDIR and OBJDIR if you have any
         split up, with new crti.o and crtn.o files resulting.          build problems with xsrc.
         This means that libtool needs to be rebuilt once the  
         new libraries are installed.  The process of rebuilding  20100522:
         libtool will cause it to automatically notice the new          private section of <ctype.h> was splitted, and now mklocale(1)
         required files, but it *must* be rebuilt in order to          include ctype_local.h, so you have to make cleandir in tools/mklocale.
         do this.  
   20100520:
         An out-of-date libtool will result in shared libraries          The location of the xkb compiled descriptions has changed. Please
         which lack _init() and _fini() routines, which means that          remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
         their global contructors/destructors will not be invoked.  
   20100222:
 20021121:          The shared objects file extension has been changed from .so to
         A bug related to how ARM ELF objects were tagged has been          .pico, in order to avoid conflicts with shared libraries names
         corrected.          libXX.so.  All now stale regular .so files can be removed from
           your object directories.
         NetBSD ARM ELF uses the soft-VFP floating point model by  
         default.  However, the assembler lacked support for marking  20100204:
         objects as using the VFP floating point format, and the          The termcap database has been removed from the sources,
         compiler was not properly passing the flag indicating "soft-VFP"          but has not been marked obsolete so it is not removed

           As such, you will need to remove them from your object
         Unfortunately, this means that the linker will now consider          and destination directories.

         incompatible with new (properly marked) objects.  20091101:
           After updating, it may be necessary to make the 'cleandir'
         The problem will only manifest itself if you attempt to compile          target in src/tools/yacc/ and in src/usr.bin/yacc/ before a

         markings.  ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES  
         WILL CONTINUE TO WORK PROPERLY.  20091001:
           On amd64 you must rebuild tools (to get the new binutils)
         The only work-around for the problem is to recompile all of          before building a kernel, or the build fails on cpufunc.S.

         system libraries is to install a binary snapshot; they are  20091001:

         if you wish to link new programs against those libraries.          it is in, and retry your build.
   
         If you have questions about this matter, please contact  20090718:
         port-arm@netbsd.org.          libc build changed so that strchr() provides the extra entry
           point for index(). Update build of libc.a (and libc_pic.a)

         Systrace has been improved to support privilege elevation.          (Similarly for strrchr() and rindex().)
         Updating the kernel requires the userland part of systrace  
         to be rebuilt.  20090709:
           Native Xorg was upgraded again.  Builds will probably fail again
 20021010:          without a clean objdir, at least for src/external/mit/xorg.
         The config(8) grammar was changed to allow options to register  
         dependencies on attributes, as well as other options.  Users  20090616:

           to avoid using the old assembly stub.
 20020922:

              rebuild PostgreSQL with the new time_t, then restore.
         Add the following into /etc/group:  
   20081219:
         smmsp:*:17:          config(1) has been updated, and one of the files it creates -
           swapnetbsd.o - has changed format.  You need to rebuild config
         and the following to /etc/master.passwd (via vipw):          (done automatically by build.sh) and then you need to rerun
           config on all kernel configuration files before rebuilding those
         smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin          kernels.
   
 20020515:  20081205:
         sshd user/group has been added.  Need to hand add this in, or sshd          If you build with MKX11=no, you should remove /etc/rc.d/xdm and
         will not let you log in (with default, or UsePrivlegeSeparation=yes)          /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.
         Add the following into /etc/group:  
   20081122:
         sshd:*:16:          On i386, various kernel options(4) in GENERIC including
           file systems have been disabled and moved into kernel modules.
         and the following to /etc/master.passwd (via vipw):          Before trying a new GENERIC kernel, you have to prepare the
           following files as well as a new GENERIC kernel:
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin  
           - build and install kernel modules from src/sys/modules
         Also /var/chroot/sshd directory needs to be present (digged as part of  
         the build process).          - install the latest bootloader, which will load a module
             for the file system from which the kernel is loaded automatically
 20020426:  
         NBUILDJOBS obsoleted in favor of just using -j.          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
 20020426:          file system module manually on the boot prompt or in the boot.cfg file.
         etc/postinstall added, which performs various checks for  
         configuration file updates and changes, and can fix most of  20080827:
         the problems identified.          If you built and installed a libc from sources between
         This should make it much easier to upgrade a system's          2008/08/20 and 2008/08/26 you got a broken strtouq(3)
         configuration from earlier systems (as far back as NetBSD 1.5).          which results in false errors reported by lint(1).
           Since this breaks the libc build itself, manual help is
 20020320:          needed -- lint must be disabled temporarily, e.g.:
         <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.            $ (cd lib/libc && make MKLINT=no dependall install)
         Build and install at usr.bin/xinstall before the build.  
   20080813:
 20020319:          MKDEBUG build was broken because the .depend files did not know
         Raw IPv6 socket now makes strict checking for sa_family and sa_len          about .go files. You need to remove all .depend files and rebuild.
         on send(2) operation.  Be sure to have sbin/rtsol and usr.sbin/rtsold  
         newer than November 2001 when you upgrade the kernel.  20080802:
           A regression in binary compatibility for pthread_mutex_t has
 20020311:          been fixed. Unfortunately, the price is breaking compatibility
         ssh configuration files were moved from /etc to /etc/ssh.  Beware          for -current.
         if you restart your machine from remote.  Note that sshd.conf needs  
         to be changed (due to the use of "/etc" inside).          Threaded programs (using libpthread) and C++ programs (using
           libstdc++) compiled after 20070907 and before 20080802 need to
 20020223:          be recompiled.
         Users of the VAX port will need to rebuild and install gas  
         so it deal with the now present register prefix used in all          One way to find affected pkgsrc packages:
         the VAX assembly files.

 20020118:            $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
         ntpd user/group has been added.  Need to hand add this in or builds  
         will break as mtree aborts early.  20080731:
           WAPBL (metadata journaling support) has been added, but at this
         Add the following into /etc/group:          time isn't backwards compatible with pre-WAPBL aware kernels
           and userland (fsck_ffs in particular).  Please make sure you
         ntpd:*:15:          don't use a journaled filesystem with an older kernel/userland,
           especially an uncleanly mounted journaled filesystem.  WAPBL
         and the following to /etc/master.passwd (via vipw):          also requires the super block to be in the UFS2 format.  You
           can use fsck_ffs -c 4 to update the superblock format.
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin  
   20080721:

         reloc errors from the toolchain groff binary this means your native  
         toolchain has some broken C++ bits.  20080531:
           The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
         To fix:          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
           utility needs to be rebuilt and reinstalled as older binaries
         Build a new toolchain (i.e. build.sh -t)          won't work correctly. The following sequence of commands:
         Use the new toolchain to build and install natively (i.e. /usr/lib)  
             $ (cd sys/sys/ && nbmake-$arch includes)
         gnu/lib/libgcc            $ (cd sbin/drvctl/ && nbmake-$arch clean)
         gnu/lib/libstdc++            $ (cd sbin/drvctl/ && nbmake-$arch all)
   
         After this a snapshot will be able to be built.          leaves new drvctl utility in sbin/drvctl build directory.
   
 20011201:  20080503:
         In order for a sparc64 build to work you must have a working awk. If          The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.

   20080303:
 20011128:          Linker warnings are now fatal if $WARNS>0.
         Kernel config information was changed to use defflag in  
         the various "files" files.  Bug fixes to config(8) are  20080126:

         UPDATING for these systems, as tool updating is taken care of  20071028:
         by the new build system.          The pccons(4) driver has been removed from the NetBSD/shark port.
           You need to update any custom kernel configuration file you have
 20011028:          to remove any references to pccons (which includes removing the
         src/etc/Makefile now needs install to be able to handle          now useless XSERVER option) and replace them with the correct
         symlinks that point to nowhere. A bug in install that          entries for the wscons driver.  See the GENERIC configuration file
         prevented this was corrected.          for more details.
   
         Solution: update and reinstall usr.bin/xinstall  20070913:
         Better Solution: Use the new toolchain and it will just work          A latent bug in dhclient/dhcpd that caused it to be unable to
         for you.          enumerate interfaces was fixed.  The bug began to cause
           problems after 20070911 when the kernel's SIOCGIFCONF
 20011006:          implementation was repaired.  From 20070529 to 20070911 racoon
         /etc/mtree/NetBSD.dist has been updated to take advantage of          could not enumerate interfaces.  (These are noted because
         absolute path support added to mtree(8). Older mtree(8)s don't          normal kernel/userspace version matching hygiene is not
         understand the format.          sufficient to avoid this problem.)  Ensure that both kernel
           and userland are from after 20070913.
         Solution: update and reinstall usr.sbin/mtree  
   20070703:
 20011004:          nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
         Crunchgen has been updated to work via reach-over makefiles. Updating          calls the target-specific strip program, and the logic to pass
         is suggested before running a snapshot build          down STRIP from make has been removed.  This requires a
           re-installation of tools.
 20010915:  
         The new "ubcperf" code committed by Chuck Silvers removed  20070422:
         a header file, uvm/uvm_vnode.h.  There may be stale .depend          The way OS emulations lookup filenames inside the emulation root
         files that still reference this file.          has been changed.  Rather than modify the pathname (and copy back
           to userspace) namei() and lookup() directly check the emulation
         Solution: "make cleandir && make dependall" in affected          root. One side effect is that absolute symlinks inside the emulated
         directories.          root file system will be relative to that file system - unless they
           start /../ this is useful when the emulated root is a real install

         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so          Following the move of string_to_flags() and flags_to_string()
         before starting your build.          from the bin/ls/ sources to libutil, users doing UPDATE builds

         get/setprogname() added. Any hostprogs that may use this will need  
         to be bootstrapped manually until the host system is current.  20060703:
           MPACPI is no more. We always configure PCI interrupts using ACPI
         Known problems: sys/arch/macppc/stand/fixcoff          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed

         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}.
