 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.

 20020906:  20081219:
         gehenna-devsw has been merged into the trunk. Need to update and          config(1) has been updated, and one of the files it creates -
         reinstall usr.sbin/config before build the kernel.          swapnetbsd.o - has changed format.  You need to rebuild config
           (done automatically by build.sh) and then you need to rerun
 20020822:          config on all kernel configuration files before rebuilding those
         Crunched rescue tools (contents of /bin and /sbin, plus others)          kernels.
         are now provided in /rescue.  
   20081205:
         To ensure that these are built statically linked (no matter          If you build with MKX11=no, you should remove /etc/rc.d/xdm and
         what the setting of LDSTATIC is), use a crunchgen(1) built          /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
         from sources newer than 20020820 (see the next entry).          set and will appear as extra files for MKX11=no update builds.
   
 20020820:  20081122:
         crunchgen(1) changed to ensure that the generated program          On i386, various kernel options(4) in GENERIC including
         is statically linked.          file systems have been disabled and moved into kernel modules.
           Before trying a new GENERIC kernel, you have to prepare the
         Solution: update and reinstall usr.bin/crunch          following files as well as a new GENERIC kernel:
   
 20020515:          - build and install kernel modules from src/sys/modules
         sshd user/group has been added.  Need to hand add this in, or sshd  
         will not let you log in (with default, or UsePrivlegeSeparation=yes)          - install the latest bootloader, which will load a module
             for the file system from which the kernel is loaded automatically
         Add the following into /etc/group:  
           If you have to load your kernel from a file system which is not of
         sshd:*:16:          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.
         and the following to /etc/master.passwd (via vipw):  
   20080827:
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin          If you built and installed a libc from sources between
           2008/08/20 and 2008/08/26 you got a broken strtouq(3)
         also /var/chroot/sshd directory needs to be present (digged as a part of          which results in false errors reported by lint(1).
         build process).          Since this breaks the libc build itself, manual help is
           needed -- lint must be disabled temporarily, e.g.:
 20020426:            $ (cd lib/libc && make MKLINT=no dependall install)
         NBUILDJOBS obsoleted in favor of just using -j.  
   20080813:
 20020426:          MKDEBUG build was broken because the .depend files did not know
         etc/postinstall added, which performs various checks for          about .go files. You need to remove all .depend files and rebuild.
         configuration file updates and changes, and can fix most of  
         the problems identified.  20080731:
         This should make it much easier to upgrade a system's          WAPBL (metadata journaling support) has been added, but at this
         configuration from earlier systems (as far back as NetBSD 1.5).          time isn't backwards compatible with pre-WAPBL aware kernels
           and userland (fsck_ffs in particular).  Please make sure you
 20020320:          don't use a journaled filesystem with an older kernel/userland,
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.          especially an uncleanly mounted journaled filesystem.  WAPBL
         build and install at usr.bin/xinstall before the build.          also requires the super block to be in the UFS2 format.  You
           can use fsck_ffs -c 4 to update the superblock format.
 20020319:  
         raw IPv6 socket now makes strict checking for sa_family and sa_len  20080721:
         on send(2) operation.  be sure to have sbin/rtsol and usr.sbin/rtsold          Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
         newer than November 2001 when you upgrade the kernel.          isn't defined.
   
 20020311:  20080531:
         ssh configuration files were moved from /etc to /etc/ssh.  Beware          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
         if you restart your machine from remote.  Note that sshd.conf needs          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
         to be changed (due to the use of "/etc" inside).          utility needs to be rebuilt and reinstalled as older binaries
           won't work correctly. The following sequence of commands:
 20020223:  
         Users of the VAX port will need to rebuild and install gas            $ (cd sys/sys/ && nbmake-$arch includes)
         so it deal with the now present register prefix used in all            $ (cd sbin/drvctl/ && nbmake-$arch clean)
         the VAX assembly files.            $ (cd sbin/drvctl/ && nbmake-$arch all)
   
 20020118:          leaves new drvctl utility in sbin/drvctl build directory.
   
         ntpd user/group has been added.  Need to hand add this in or builds  20080503:
         will break as mtree aborts early.          The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
   
         Add the following into /etc/group:  20080521:
           For a while, unprivileged UPDATE builds would fail to
         ntpd:*:15:          succeed at the checkflist stage, complaining that
           ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
         and the following to /etc/master.passwd (via vipw):          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
           If you already hit this problem, update the .mk file,
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin          remove ${DESTDIR}/stand/<arch>, and re-run the build.
   
 20011207:  20080303:
           Linker warnings are now fatal if $WARNS>0.
         If you're attempting to build a snapshot on sparc64 and are getting  
         reloc errors from the toolchain groff binary this means your native  20080126:
         toolchain has some broken C++ bits.          The posix_fadvise system call has been changed from an assembly
           stub, to a c file that calls an assembly stub. You need to
         To fix:          'rm -f posix_fadvise.* .depend' in the libc build directory to
           avoid using the old assembly stub.
         Build a new toolchain (i.e. build.sh -t)  
         Use the new toolchain to build and install natively (i.e. /usr/lib)  20071209:
           The acpiec(4) driver has been split into two attachments. If you
         gnu/lib/libgcc          get ACPI errors before the attachment, please update your kernel
         gnu/lib/libstdc++          configuration file appropriately or see GENERIC for more details.
   
         After this a snapshot will be able to be built.  20071115:
           The it(4) driver has been renamed to itesio(4) and the old port
 20011201:          argument specified in the kernel configuration file is not valid
         In order for a sparc64 build to work you must have a working awk. If          anymore. The itesio(4) driver now uses the Super I/O address port
         you've built and installed a system with the new toolchain up to this          rather than the EC address port. Please update your kernel
         point you do not have a working awk as its ability to do floating          configuration file appropriately or see GENERIC for more details.
         point is broken.  
   20071028:
         To build:          The pccons(4) driver has been removed from the NetBSD/shark port.
           You need to update any custom kernel configuration file you have
         remake and install gnu/lib/libgcc          to remove any references to pccons (which includes removing the
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links          now useless XSERVER option) and replace them with the correct
         against the new libgcc.a)          entries for the wscons driver.  See the GENERIC configuration file
           for more details.
 20011128:  
         Kernel config information was changed to use defflag in  20070913:
         the various "files" files.  Bug fixes to config(8) are          A latent bug in dhclient/dhcpd that caused it to be unable to

         to build and install in usr.sbin/config before attempting          problems after 20070911 when the kernel's SIOCGIFCONF
         to build a new kernel.          implementation was repaired.  From 20070529 to 20070911 racoon
           could not enumerate interfaces.  (These are noted because
 20011030:          normal kernel/userspace version matching hygiene is not
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)          sufficient to avoid this problem.)  Ensure that both kernel
         before building libc.          and userland are from after 20070913.
   
 20011029:  20070703:
         The new document BUILDING.mdoc (view with nroff | more, or          nbinstall has been renamed as it calls the target specific and
         see pre-generated .txt and .html versions) describes the build          the logic to pass down STRIP from mk been removed.  This forces

         UPDATING for these systems, as tool updating is taken care of          root. One side effect is that absolute symlinks inside the emulated
         by the new build system.          root file system will be relative to that file system - unless they
           start /../ this is useful when the emulated root is a real install
 20011028:          that has such links.
         src/etc/Makefile now needs install to be able to handle          This might affect symlinks that have been added to reference outside
         symlinks that point to nowhere. A bug in install that          the emulated root.
         prevented this was corrected.  
   20070412:
         Solution: update and reinstall usr.bin/xinstall          The pckbc driver on sgimips IP32 has been removed. Use macekbc
         Better Solution: Use the new toolchain and it will just work          instead. See the GENERIC32_IP3x kernel configuration for an
         for you.          example.
   
 20011006:  20070319:
         /etc/mtree/NetBSD.dist has been updated to take advantage of          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
         absolute path support added to mtree(8). Older mtree(8)s don't          on many platforms due to incorrect flags settings.  If you

         Crunchgen has been updated to work via reach-over makefiles. Updating  
         is suggested before running a snapshot build  20070210:
           src/sys/sys/{sa.h,savar.h} were removed.
 20010915:            find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \

         files that still reference this file.  
   20070209:
         Solution: "make cleandir && make dependall" in affected          The threading model was changed when the newlock2 branch
         directories.          was merged to NetBSD-current.  If you boot with a new

           is the only threaded application in the base system.
 20010803:  
         (i386 only): i386 kernel now uses new instructions like  20061214:
         `fxsave' which old gas doesn't understand.  To build the          Following the move of string_to_flags() and flags_to_string()
         kernel successfully, you need to build and install a new toolchain,          from the bin/ls/ sources to libutil, users doing UPDATE builds
         (i.e., build.sh -t) or  (temporarily) comment out "options I686_CPU"          will need to do a "make cleandir" in
         from your kernel configuration until you rebuild your userland.                  tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,

         Bootloader update on ELF platforms.  DDB in kernels from before          file in the ls sources -- stat_flags.h has been removed.
         this will be unable to read symbol tables provided by newer  
         bootloaders.  20061108:
           The configure script used in the src/tools/gcc compiler has been
 20010726:          changed to indicate that our libc has ssp support built-in and
         Texinfo was updated to 4.0.  To avoid failures when trying to          does not depend on -lssp and -lssp-nonshared. You'll need to
         build the included texinfo files, do:          make clean in src/tools/gcc first to rebuild the compiler.

         make MKINFO=no dependall install          The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
           available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
 20010718:  
         Enabled correct .init/.fini processing in crt0.  The way this  20060814:
         was done was to change a -I directive to cc(1), which means          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
         make(1) will have a stale dependency (it will be checking the          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         timestamp on the wrong "dot_init.h").          kernel configuration for an example.  X servers from the last
           few years should cope.
         The symptom you will see is that new programs die with SIGSEGV  
         if you have a stale dependency.  20060703:
           MPACPI is no more. We always configure PCI interrupts using ACPI
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
         before starting your build.          to ACPI_SCANPCI. Thanks to work from fvdl.
   
 20010628:  20060627:
         A construct was added to uvm_page.h that uncovered a bug          socket(2) has changed, and its system call has been versioned.
         in lint(1).  If you get a warning/error about a non-portable          For userlands with the old version of socket(2), make sure that
         bitfield, update your lint(1) before proceeding.          your kernel has 'options COMPAT_30' set, or else 'bad system call'
           errors will result.
 20010226:  
         Added named user/group to system. Need to hand add this in or builds  
         will break as mtree aborts early.  
   
         To work around add by hand:  
   
         named:*:14:  
   
         to /etc/group and add:  
   
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin  
   
         to master.passwd (use vipw for instance if doing by hand).  
   
         Now a make build should progress.  
   
 20010219:  
         get/setprogname() added. Any hostprogs that may use this will need  
         to be bootstrapped manually until the host system is current.  
   
         Known problems: sys/arch/macppc/stand/fixcoff  
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to  
                           CFLAGS and rebuilding should work)  
                         usr.sbin/mdsetimage - Build a static copy if  
                           building a snapshot before fully bootstrapped.  
   
 20010204:  
         prepare the code to compile with stricter gcc flags. in  
         particular start eliminating redundant declarations. Yacc  
         needs to be installed before make build.  
   
 20010114:  
         introduce .if commands(target) in make(1). You need to  
         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}.
