 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.
 For a more detailed description see Makefile.  See also: BUILDING, build.sh, Makefile.
 Note that users of the new toolchain in many instances will not  
 experience the problems listed below because their host tools are  
 automatically generated for them.

 20011028:  20090110:
         /usr/src/build.sh exists as of 2001.10.19. From the cvs log:          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
           1. Make sure your kernel has COMPAT_50 in it. Build and install.
         "Script to automate bootstrapping a build on any host platform.          2. make sure build.sh completes and the binaries in a chroot work
          Creates a bmake (rebuilds, if necessary) and invokes that to             before installing.
          start the build."          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
         This should, incidentally, allow 1.5.x hosts to build -current             are installed properly, and start building libraries first libc
         using the new toolchain, on USE_NEW_TOOLCHAIN-enabled platforms.             and libutil, install them and then continue building all the
              libraries in src/lib and src/gnu/lib and install them. Once
 20011028:             the new libraries are installed, you can restart the build.
         src/etc/Makefile now needs install to be able to handle          4. If you compile packages and you notice link time warnings,
         symlinks that point to nowhere. A bug in install that             you'll need to bump them and rebuild them.
         prevented this was corrected.          5. Next time you run pwd_mkdb with the new binary, the file
              will be upgraded and it will not be backwards compatible.
         Solution: update and reinstall usr.bin/xinstall          6. The utmpx/wtmpx files have been versioned, and there is
         Better Solution: Use the new toolchain and it will just work             a heuristic for utmp. You are better off removing the
         for you.             old files after upgrading.
 20011006:  20081219:
         /etc/mtree/NetBSD.dist has been updated to take advantage of          config(1) has been updated, and one of the files it creates -
         absolute path support added to mtree(8). Older mtree(8)s don't          swapnetbsd.o - has changed format.  You need to rebuild config
         understand the format.          (done automatically by build.sh) and then you need to rerun
           config on all kernel configuration files before rebuilding those
         Solution: update and reinstall usr.sbin/mtree          kernels.
 20011004:  20081205:
           If you build with MKX11=no, you should remove /etc/rc.d/xdm and
         Crunchgen has been updated to work via reach-over makefiles. Updating          /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
         is suggested before running a snapshot build          set and will appear as extra files for MKX11=no update builds.
 20010922:  20081122:
         The new toolchain is enabled on i386.  This new build method          On i386, various kernel options(4) in GENERIC including
         is intended to make all the upgrade issues elsewhere in UPDATING          file systems have been disabled and moved into kernel modules.
         obsolete (stay tuned...).          Before trying a new GENERIC kernel, you have to prepare the
           following files as well as a new GENERIC kernel:
         i386 platform builds must now set TOOLDIR in mk.conf or the  
         environment in order to build the system.  This is a pathname          - build and install kernel modules from src/sys/modules
         where host build tools will be installed, and must NOT be  
         the same as src/tools.          - install the latest bootloader, which will load a module
             for the file system from which the kernel is loaded automatically
         (Optionally, USETOOLS=no can be set in the environment if you  
         wish to avoid using the separate host toolchain for building a          If you have to load your kernel from a file system which is not of
         subtree.  Otherwise, this will default to "yes" automatically.)          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.
         The new "ubcperf" code committed by Chuck Silvers removed  20080827:
         a header file, uvm/uvm_vnode.h.  There may be stale .depend          If you built and installed a libc from sources between
         files that still reference this file.          2008/08/20 and 2008/08/26 you got a broken strtouq(3)
           which results in false errors reported by lint(1).
         Solution: "make cleandir && make dependall" in affected          Since this breaks the libc build itself, manual help is
         directories.          needed -- lint must be disabled temporarily, e.g.:
             $ (cd lib/libc && make MKLINT=no dependall install)
         grep.info is now built from grep.texi using makeinfo.  Since it  20080813:
         requires makeinfo v4.0, you need to install new texinfo before          MKDEBUG build was broken because the .depend files did not know
         building gnu/usr.bin/grep.  To install new texinfo, please follow          about .go files. You need to remove all .depend files and rebuild.
         the instruction described in 20010726 entry.  
 20010803:          WAPBL (metadata journaling support) has been added, but at this
         (i386 only): i386 kernel now uses new instructions like          time isn't backwards compatible with pre-WAPBL aware kernels
         `fxsave' which old gas doesn't understand.  To build the          and userland (fsck_ffs in particular).  Please make sure you
         kernel successfuly, you need to build and install new gas          don't use a journaled filesystem with an older kernel/userland,
         (gnu/usr.bin/gas.new), or (temporarily) comment out          especially an uncleanly mounted journaled filesystem.  WAPBL
         "options I686_CPU" from your kernel configuration until you          also requires the super block to be in the UFS2 format.  You
         rebuilt your userland (and got a new gas).          can use fsck_ffs -c 4 to update the superblock format.
 20010731:  20080721:
         Bootloader update on ELF platforms.  DDB in kernels from before          Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
         this will be unable to read symbol tables provided by newer          isn't defined.
 20010726:          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
         Texinfo was updated to 4.0.  To avoid failures when trying to          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
         build the included texinfo files, do:          utility needs to be rebuilt and reinstalled as older binaries
           won't work correctly. The following sequence of commands:
         cd src/gnu/usr.bin/texinfo  
         make MKINFO=no dependall install            $ (cd sys/sys/ && nbmake-$arch includes)
             $ (cd sbin/drvctl/ && nbmake-$arch clean)
 20010718:            $ (cd sbin/drvctl/ && nbmake-$arch all)
         Enabled correct .init/.fini processing in crt0.  The way this          leaves new drvctl utility in sbin/drvctl build directory.
         was done was to change a -I directive to cc(1), which means  
         make(1) will have a stale dependency (it will be checking the  20080503:
         timestamp on the wrong "dot_init.h").          The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         The symptom you will see is that new programs die with SIGSEGV  20080521:
         if you have a stale dependency.          For a while, unprivileged UPDATE builds would fail to
           succeed at the checkflist stage, complaining that
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so          ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
         before starting your build.          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
           If you already hit this problem, update the .mk file,
 20010628:          remove ${DESTDIR}/stand/<arch>, and re-run the build.
         A construct was added to uvm_page.h that uncovered a bug  20080303:
         in lint(1).  If you get a warning/error about a non-portable          Linker warnings are now fatal if $WARNS>0.
         bitfield, update your lint(1) before proceeding.

         To work around add by hand:  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          The it(4) driver has been renamed to itesio(4) and the old port
           argument specified in the kernel configuration file is not valid
         to master.passwd (use vipw for instance if doing by hand).          anymore. The itesio(4) driver now uses the Super I/O address port
           rather than the EC address port. Please update your kernel

 20010219:  20071028:

         to be bootstrapped manually until the host system is current.          You need to update any custom kernel configuration file you have
           to remove any references to pccons (which includes removing the
         Known problems: sys/arch/macppc/stand/fixcoff          now useless XSERVER option) and replace them with the correct
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to          entries for the wscons driver.  See the GENERIC configuration file
                           CFLAGS and rebuilding should work)          for more details.

         needs to be installed before make build.          could not enumerate interfaces.  (These are noted because

         New share/mk files needed to support .WAIT in SUBDIR variables.          to userspace) namei() and lookup() directly check the emulation

           will allow dependencies on those files to get get rebuilt
           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.
           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.
           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.
           The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
           available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
           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.
           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.
           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.
