 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:
 ^^^^^^^^^^^^^^^  ^^^^^^^^^^^^^^^
   
 20020917:  20080813:
         USE_NEW_TOOLCHAIN has been replaced with:          MKDEBUG build was broken because the .depend files did not know
             -   TOOLCHAIN_MISSING -- set to "yes" on platforms for which          about .go files. You need to remove all .depend files and rebuild.
                 there is no working in-tree toolchain (hppa, ns32k, sh5,  
                 x86_64).  20080731:
             -   EXTERNAL_TOOLCHAIN -- if defined by the user, points to the          WAPBL (metadata journaling support) has been added, but at this
                 root ofan external toolchain (e.g. /usr/local/gnu).  This          time isn't backwards compatible with pre-WAPBL aware kernels
                 enables the cross-build framework even for TOOLCHAIN_MISSING          and userland (fsck_ffs in particular).  Please make sure you
                 platforms.          don't use a journaled filesystem with an older kernel/userland,
           especially an uncleanly mounted journaled filesystem.  WAPBL
 20020906:          also requires the super block to be in the UFS2 format.  You
         gehenna-devsw has been merged into the trunk. Need to update and          can use fsck_ffs -c 4 to update the superblock format.
         reinstall usr.sbin/config before build the kernel.  
   20080721:
 20020822:          Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
         Crunched rescue tools (contents of /bin and /sbin, plus others)          isn't defined.
         are now provided in /rescue.  
   20080531:
         To ensure that these are built statically linked (no matter          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
         what the setting of LDSTATIC is), use a crunchgen(1) built          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
         from sources newer than 20020820 (see the next entry).          utility needs to be rebuilt and reinstalled as older binaries
           won't work correctly. The following sequence of commands:
 20020820:  
         crunchgen(1) changed to ensure that the generated program            $ (cd sys/sys/ && nbmake-$arch includes)
         is statically linked.            $ (cd sbin/drvctl/ && nbmake-$arch clean)
             $ (cd sbin/drvctl/ && nbmake-$arch all)
         Solution: update and reinstall usr.bin/crunch  
           leaves new drvctl utility in sbin/drvctl build directory.
 20020515:  
         sshd user/group has been added.  Need to hand add this in, or sshd  20080503:
         will not let you log in (with default, or UsePrivlegeSeparation=yes)          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
         sshd:*:16:          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,
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin          remove ${DESTDIR}/stand/<arch>, and re-run the build.
   
         also /var/chroot/sshd directory needs to be present (digged as a part of  20080303:
         build process).          Linker warnings are now fatal if $WARNS>0.
   
 20020426:  20080126:
         NBUILDJOBS obsoleted in favor of just using -j.          The posix_fadvise system call has been changed from an assembly
           stub, to a c file that calls an assembly stub. You need to
 20020426:          'rm -f posix_fadvise.* .depend' in the libc build directory to
         etc/postinstall added, which performs various checks for          avoid using the old assembly stub.
         configuration file updates and changes, and can fix most of  
         the problems identified.  20071209:
         This should make it much easier to upgrade a system's          The acpiec(4) driver has been split into two attachments. If you
         configuration from earlier systems (as far back as NetBSD 1.5).          get ACPI errors before the attachment, please update your kernel
           configuration file appropriately or see GENERIC for more details.
 20020320:  
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.  20071115:
         build and install at usr.bin/xinstall before the build.          The it(4) driver has been renamed to itesio(4) and the old port
           argument specified in the kernel configuration file is not valid
 20020319:          anymore. The itesio(4) driver now uses the Super I/O address port
         raw IPv6 socket now makes strict checking for sa_family and sa_len          rather than the EC address port. Please update your kernel
         on send(2) operation.  be sure to have sbin/rtsol and usr.sbin/rtsold          configuration file appropriately or see GENERIC for more details.
         newer than November 2001 when you upgrade the kernel.  
   20071028:
 20020311:          The pccons(4) driver has been removed from the NetBSD/shark port.
         ssh configuration files were moved from /etc to /etc/ssh.  Beware          You need to update any custom kernel configuration file you have
         if you restart your machine from remote.  Note that sshd.conf needs          to remove any references to pccons (which includes removing the
         to be changed (due to the use of "/etc" inside).          now useless XSERVER option) and replace them with the correct
           entries for the wscons driver.  See the GENERIC configuration file
 20020223:          for more details.
         Users of the VAX port will need to rebuild and install gas  
         so it deal with the now present register prefix used in all  20070913:
         the VAX assembly files.          A latent bug in dhclient/dhcpd that caused it to be unable to
           enumerate interfaces was fixed.  The bug began to cause
 20020118:          problems after 20070911 when the kernel's SIOCGIFCONF
           implementation was repaired.  From 20070529 to 20070911 racoon
         ntpd user/group has been added.  Need to hand add this in or builds          could not enumerate interfaces.  (These are noted because
         will break as mtree aborts early.          normal kernel/userspace version matching hygiene is not
           sufficient to avoid this problem.)  Ensure that both kernel
         Add the following into /etc/group:          and userland are from after 20070913.
   
         ntpd:*:15:  20070703:
           nbinstall has been renamed as it calls the target specific and
         and the following to /etc/master.passwd (via vipw):          the logic to pass down STRIP from mk been removed.  This forces
           a re-installation of tools.
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin  
   20070422:
 20011207:          The way OS emulations lookup filenames inside the emulation root
           has been changed.  Rather than modify the pathname (and copy back
         If you're attempting to build a snapshot on sparc64 and are getting          to userspace) namei() and lookup() directly check the emulation
         reloc errors from the toolchain groff binary this means your native          root. One side effect is that absolute symlinks inside the emulated
         toolchain has some broken C++ bits.          root file system will be relative to that file system - unless they
           start /../ this is useful when the emulated root is a real install
         To fix:          that has such links.
           This might affect symlinks that have been added to reference outside
         Build a new toolchain (i.e. build.sh -t)          the emulated root.
         Use the new toolchain to build and install natively (i.e. /usr/lib)  
   20070412:
         gnu/lib/libgcc          The pckbc driver on sgimips IP32 has been removed. Use macekbc
         gnu/lib/libstdc++          instead. See the GENERIC32_IP3x kernel configuration for an
           example.
         After this a snapshot will be able to be built.  
   20070319:
 20011201:          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
         In order for a sparc64 build to work you must have a working awk. If          on many platforms due to incorrect flags settings.  If you
         you've built and installed a system with the new toolchain up to this          updated and built after about 20070315, do "nbmake-$arch
         point you do not have a working awk as its ability to do floating          cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
         point is broken.          rebuild of object files that might have been built
           incorrectly, and ensure that you have at least
         To build:          src/lib/libc/Makefile 1.130.
   
         remake and install gnu/lib/libgcc  20070210:
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links          src/sys/sys/{sa.h,savar.h} were removed.
         against the new libgcc.a)            find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
                 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
 20011128:          will allow dependencies on those files to get get rebuilt
         Kernel config information was changed to use defflag in  
         the various "files" files.  Bug fixes to config(8) are  20070209:
         required in order for this to work properly.  Make sure          The threading model was changed when the newlock2 branch
         to build and install in usr.sbin/config before attempting          was merged to NetBSD-current.  If you boot with a new
         to build a new kernel.          kernel (version 4.99.10), then you also need a new pthread
           library (/usr/lib/libpthread.so.0.7).  If you boot with
 20011030:          an old kernel, then you need the old pthread library
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         before building libc.          the pthread library in sync, old threaded applications should
           continue to work with an old or new kernel.  Note that named(8)
 20011029:          is the only threaded application in the base system.
         The new document BUILDING.mdoc (view with nroff | more, or  
         see pre-generated .txt and .html versions) describes the build  20061214:
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN          Following the move of string_to_flags() and flags_to_string()
         build process, are intended in the long run to replace this          from the bin/ls/ sources to libutil, users doing UPDATE builds
         manual update log.          will need to do a "make cleandir" in
                   tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
         Users building a USE_NEW_TOOLCHAIN system should read the                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
         BUILDING document for caveats.  Generally, BUILDING supersedes                  usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         UPDATING for these systems, as tool updating is taken care of                  as the installation images in distrib/
         by the new build system.          in order to excise stale references to the old stat_flags.h header
           file in the ls sources -- stat_flags.h has been removed.
 20011028:  
         src/etc/Makefile now needs install to be able to handle  20061108:
         symlinks that point to nowhere. A bug in install that          The configure script used in the src/tools/gcc compiler has been
         prevented this was corrected.          changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
         Solution: update and reinstall usr.bin/xinstall          make clean in src/tools/gcc first to rebuild the compiler.
         Better Solution: Use the new toolchain and it will just work  
         for you.  20061009:
           The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
 20011006:          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
         /etc/mtree/NetBSD.dist has been updated to take advantage of  
         absolute path support added to mtree(8). Older mtree(8)s don't  20060814:
         understand the format.          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
           withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         Solution: update and reinstall usr.sbin/mtree          kernel configuration for an example.  X servers from the last
           few years should cope.
 20011004:  
         Crunchgen has been updated to work via reach-over makefiles. Updating  20060703:
         is suggested before running a snapshot build          MPACPI is no more. We always configure PCI interrupts using ACPI
           if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
 20010915:          to ACPI_SCANPCI. Thanks to work from fvdl.
         The new "ubcperf" code committed by Chuck Silvers removed  
         a header file, uvm/uvm_vnode.h.  There may be stale .depend  20060627:
         files that still reference this file.          socket(2) has changed, and its system call has been versioned.
           For userlands with the old version of socket(2), make sure that
         Solution: "make cleandir && make dependall" in affected          your kernel has 'options COMPAT_30' set, or else 'bad system call'
         directories.          errors will result.
   
 20010803:  
         grep.info is now built from grep.texi using makeinfo.  Since it  
         requires makeinfo v4.0, you need to install new texinfo before  
         building gnu/usr.bin/grep.  To install new texinfo, please follow  
         the instruction described in 20010726 entry.  
   
 20010803:  
         (i386 only): i386 kernel now uses new instructions like  
         `fxsave' which old gas doesn't understand.  To build the  
         kernel successfully, you need to build and install a new toolchain,  
         (i.e., build.sh -t) or  (temporarily) comment out "options I686_CPU"  
         from your kernel configuration until you rebuild your userland.  
         See 20011029 above and BUILDING file in this directory for more information.  
         [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]  
   
 20010731:  
         Bootloader update on ELF platforms.  DDB in kernels from before  
         this will be unable to read symbol tables provided by newer  
         bootloaders.  
   
 20010726:  
         Texinfo was updated to 4.0.  To avoid failures when trying to  
         build the included texinfo files, do:  
   
         cd src/gnu/usr.bin/texinfo  
         make MKINFO=no dependall install  
   
 20010718:  
         Enabled correct .init/.fini processing in crt0.  The way this  
         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  
         timestamp on the wrong "dot_init.h").  
   
         The symptom you will see is that new programs die with SIGSEGV  
         if you have a stale dependency.  
   
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so  
         before starting your build.  
   
 20010628:  
         A construct was added to uvm_page.h that uncovered a bug  
         in lint(1).  If you get a warning/error about a non-portable  
         bitfield, update your lint(1) before proceeding.  
   
 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}.
