 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.

         A sign exension bug was fixed which set all the high bits          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
         of our newly expanded ffs fs_flags.  This should only          1. Make sure your kernel has COMPAT_50 in it. Build and install.
         affect users who installed or upgraded in September of 2003.             This is needed even in the MODULAR kernel because there is
         A small utility program was posted to tech-kern which             conditionally compiled code in rtsock.c.
         should fix this problem, and a warning message was added          2. make sure build.sh completes and the binaries in a chroot work
         to the kernel which should discover and warn about it.  See             before installing.
         http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html          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
 20030906:             are installed properly, and start building libraries first libc
         With the addition of siginfo support the old signal trampoline             and libutil, install them and then continue building all the
         code has been deprecated to COMPAT_16. Make sure that your running             libraries in src/lib and src/gnu/lib and install them. Once
         kernel has COMPAT_16 enabled before building userland.             the new libraries are installed, you can restart the build.
           4. If you compile packages and you notice link time warnings,
 20030801:             rebuild the required packages to update their shared libraries.
         With the new openssl, there is some header and library shuffling.             Any package you rebuild will require rebuilding all the packages
         rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \             that depend on it.
         /usr/lib/libdes* before building.          5. Next time you run pwd_mkdb with the new binary, the file
              will be upgraded and it will not be backwards compatible.
 20030703:          6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
         Texinfo was updated to 4.6.  To avoid failures when trying to             lastlogx(5)) have been versioned, and there is a heuristic
         build the included texinfo files, do:             for utmp. You are better off removing the old files after
              upgrading.  The automated clearing of /var/run during
         cd src/gnu/usr.bin/texinfo             boot, and the automated rotating of files in /var/log by
         make MKINFO=no dependall install             newsyslog(8), may mean that you do not have to remove the
              files manually.
 20030630:          7. The optional accounting file (/var/account/acct, see
         Groff was updated to 1.19; it's probably necessary to do             accton(8)) has not been versioned, and will need to be
                 cd share/mk && make install             removed.  The automatic rotation of the accounting file by
                 cd src/gnu/usr.bin/groff             /etc/daily limits the bad consequences of failure to remove
                 make MKMAN=no dependall install             the file.
         (untested).          8. Application software that writes time_t to binary files on
              disk will break or need attention. Most notably: if you are
 20030516:             using PostgreSQL < 8.4, you need to dump your databases,
         Due to bugs in the export handling code, invalid export lines             rebuild PostgreSQL with the new time_t, then restore.
         were accepted before and caused the kernel to panic when  
         mountd got restarted because it freed memory that had already  20081219:
         been freed. This has been fixed and the kernel checks          config(1) has been updated, and one of the files it creates -
         export addresses very strictly. If you upgrade your kernel,          swapnetbsd.o - has changed format.  You need to rebuild config
         make sure you also upgrade mountd, because if your export          (done automatically by build.sh) and then you need to rerun
         file contains lines with an old inet4 address syntax (i.e.          config on all kernel configuration files before rebuilding those
         a.b.c or a.b or a), they will get rejected by the new kernel.          kernels.
 20030402:  20081205:
         The superblock layout for FFS was changed.  If you have 1.6          If you build with MKX11=no, you should remove /etc/rc.d/xdm and
         fsck binaries, they will signal a fatal superblock mismatch          /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
         with the first alternate, because they compare too many          set and will appear as extra files for MKX11=no update builds.
         fields (even ones that aren't useful).  If possible, upgrade  
         your fsck_ffs binary before using a new kernel.  20081122:
         None of this signals actual filesystem damage.          On i386, various kernel options(4) in GENERIC including
           file systems have been disabled and moved into kernel modules.
 20030324:          Before trying a new GENERIC kernel, you have to prepare the
         sendmail version 8.12.8 was imported.  Since sendmail is          following files as well as a new GENERIC kernel:
         now setgid to the smmsp group, and runs in "collection"  
         mode for most common activities, there is a new config          - build and install kernel modules from src/sys/modules
         file called submit.cf that needs to live in /etc/mail.  
         The generic submit.cf sample in /usr/share/sendmail/cf          - install the latest bootloader, which will load a module
         is named netbsd-msp.cf.  Upgrading your regular sendmail            for the file system from which the kernel is loaded automatically
         configuration file is also strongly advised.  
           If you have to load your kernel from a file system which is not of
         See the section named "MESSAGE SUBMISSION PROGRAM" in          the same type as the root file system, you have to load the necessary
         the updated /usr/share/sendmail/README file for more          file system module manually on the boot prompt or in the boot.cfg file.
 20030117:          If you built and installed a libc from sources between
         Texinfo was updated to 4.3.  To avoid failures when trying to          2008/08/20 and 2008/08/26 you got a broken strtouq(3)
         build the included texinfo files, do:          which results in false errors reported by lint(1).
           Since this breaks the libc build itself, manual help is
         cd src/gnu/usr.bin/texinfo          needed -- lint must be disabled temporarily, e.g.:
         make MKINFO=no dependall install            $ (cd lib/libc && make MKLINT=no dependall install)
 20021223:  20080813:
         The METALOG format changed slightly, to remove the leading          MKDEBUG build was broken because the .depend files did not know
         "${DESTDIR}" from path names.          about .go files. You need to remove all .depend files and rebuild.
         This only affects people building with UNPRIVED.  
         For complete safety, remove the DESTDIR entirely and  20080802:
         update tools/mtree, before running make build.          A regression in binary compatibility for pthread_mutex_t has
           been fixed. Unfortunately, the price is breaking compatibility
 20021219:          for -current.
         CVS repository layout was changed.  See the following for details  
         if you are using (anonymous) cvs to update your tree.          Threaded programs (using libpthread) and C++ programs (using
           libstdc++) compiled after 20070907 and before 20080802 need to
         http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html          be recompiled.
 20021219:          One way to find affected pkgsrc packages:
         install(1) had a '-N dbdir' option added, to specify an  
         alternate location to look up users & groups (instead            $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
         of the host system passwd(5) and group(5) databases).            $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
         The build system was modified to take advantage of  20080731:
         this option (using ${NETBSDSRCDIR}/etc), so if you          WAPBL (metadata journaling support) has been added, but at this
         use USETOOLS==no, you may have to rebuild and          time isn't backwards compatible with pre-WAPBL aware kernels
         reinstall usr.bin/xinstall first.          and userland (fsck_ffs in particular).  Please make sure you
           don't use a journaled filesystem with an older kernel/userland,
 20021130:          especially an uncleanly mounted journaled filesystem.  WAPBL
         fparseln(3) moved from libutil to libc.          also requires the super block to be in the UFS2 format.  You
         If building to DESTDIR=/, reinstall the includes          can use fsck_ffs -c 4 to update the superblock format.
         and rebuild libc:  
                 make includes  20080721:
                 make do-lib-libc          Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
         If using build.sh, "cd tools/compat && make clean"          isn't defined.
         before rebuilding the tools.  
 20021126:          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
         The mk.conf(5) variable SYS_INCLUDE has been deprecated,          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
         including the optional "SYS_INCLUDE=symlinks" support.          utility needs to be rebuilt and reinstalled as older binaries
         All header files, including <sys/*.h> are copied into          won't work correctly. The following sequence of commands:
             $ (cd sys/sys/ && nbmake-$arch includes)
 20021121:            $ (cd sbin/drvctl/ && nbmake-$arch clean)
         The C run-time support files crtbegin.o and crtend.o            $ (cd sbin/drvctl/ && nbmake-$arch all)
         (and their companions crtbeginS.o and crtendS.o) were  
         split up, with new crti.o and crtn.o files resulting.          leaves new drvctl utility in sbin/drvctl build directory.
         This means that libtool needs to be rebuilt once the  
         new libraries are installed.  The process of rebuilding  20080503:
         libtool will cause it to automatically notice the new          The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         required files, but it *must* be rebuilt in order to  
         do this.  20080521:

         An out-of-date libtool will result in shared libraries          succeed at the checkflist stage, complaining that

         their global contructors/destructors will not be invoked.          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
           If you already hit this problem, update the .mk file,
 20021121:          remove ${DESTDIR}/stand/<arch>, and re-run the build.
         A bug related to how ARM ELF objects were tagged has been  
         corrected.  20080303:
           Linker warnings are now fatal if $WARNS>0.
         NetBSD ARM ELF uses the soft-VFP floating point model by  
         default.  However, the assembler lacked support for marking  20080126:
         objects as using the VFP floating point format, and the          The posix_fadvise system call has been changed from an assembly

           avoid using the old assembly stub.
         Unfortunately, this means that the linker will now consider

         certain shared libraries are installed into /lib, the shared  
         linker is installed into /libexec, and all programs in /bin  20070319:
         and /sbin are dynamically linked.          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so

                 enables the cross-build framework even for TOOLCHAIN_MISSING  
                 platforms.  20070209:

         gehenna-devsw has been merged into the trunk. Need to update and          kernel (version 4.99.10), then you also need a new pthread
         reinstall usr.sbin/config before building the kernel.          library (/usr/lib/libpthread.so.0.7).  If you boot with
           an old kernel, then you need the old pthread library
 20020822:          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         Crunched rescue tools (contents of /bin and /sbin, plus others)          the pthread library in sync, old threaded applications should
         are now provided in /rescue.          continue to work with an old or new kernel.  Note that named(8)
           is the only threaded application in the base system.
         To ensure that these are built statically linked (no matter  
         what the setting of LDSTATIC is), use a crunchgen(1) built  20061214:
         from sources newer than 20020820 (see the next entry).          Following the move of string_to_flags() and flags_to_string()

         Solution: update and reinstall usr.bin/crunch                  as the installation images in distrib/
           in order to excise stale references to the old stat_flags.h header
 20020605:          file in the ls sources -- stat_flags.h has been removed.
         smmsp user/group has been added for sendmail.  
         Add the following into /etc/group:          The configure script used in the src/tools/gcc compiler has been
           changed to indicate that our libc has ssp support built-in and
         smmsp:*:17:          does not depend on -lssp and -lssp-nonshared. You'll need to
           make clean in src/tools/gcc first to rebuild the compiler.
         and the following to /etc/master.passwd (via vipw):  
         smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin          The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
           available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.

         Add the following into /etc/group:          kernel configuration for an example.  X servers from the last
           few years should cope.
         and the following to /etc/master.passwd (via vipw):          MPACPI is no more. We always configure PCI interrupts using ACPI
           if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin          to ACPI_SCANPCI. Thanks to work from fvdl.
         Also /var/chroot/sshd directory needs to be present (digged as part of  20060627:
         the build process).          socket(2) has changed, and its system call has been versioned.
           For userlands with the old version of socket(2), make sure that
 20020426:          your kernel has 'options COMPAT_30' set, or else 'bad system call'
         NBUILDJOBS obsoleted in favor of just using -j.          errors will result.
         etc/postinstall added, which performs various checks for  
         configuration file updates and changes, and can fix most of  
         the problems identified.  
         This should make it much easier to upgrade a system's  
         configuration from earlier systems (as far back as NetBSD 1.5).  
         <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.  
         Build and install at usr.bin/xinstall before the build.  
         Raw IPv6 socket now makes strict checking for sa_family and sa_len  
         on send(2) operation.  Be sure to have sbin/rtsol and usr.sbin/rtsold  
         newer than November 2001 when you upgrade the kernel.  
         ssh configuration files were moved from /etc to /etc/ssh.  Beware  
         if you restart your machine from remote.  Note that sshd.conf needs  
         to be changed (due to the use of "/etc" inside).  
         Users of the VAX port will need to rebuild and install gas  
         so it deal with the now present register prefix used in all  
         the VAX assembly files.  
         ntpd user/group has been added.  Need to hand add this in or builds  
         will break as mtree aborts early.  
         Add the following into /etc/group:  
         and the following to /etc/master.passwd (via vipw):  
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin  
         If you're attempting to build a snapshot on sparc64 and are getting  
         reloc errors from the toolchain groff binary this means your native  
         toolchain has some broken C++ bits.  
         To fix:  
         Build a new toolchain (i.e. build.sh -t)  
         Use the new toolchain to build and install natively (i.e. /usr/lib)  
         After this a snapshot will be able to be built.  
         In order for a sparc64 build to work you must have a working awk. If  
         you've built and installed a system with the new toolchain up to this  
         point you do not have a working awk as its ability to do floating  
         point is broken.  
         To build:  
         remake and install gnu/lib/libgcc  
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links  
         against the new libgcc.a)  
         Kernel config information was changed to use defflag in  
         the various "files" files.  Bug fixes to config(8) are  
         required in order for this to work properly.  Make sure  
         to build and install in usr.sbin/config before attempting  
         to build a new kernel.  
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)  
         before building libc.  
         The new document BUILDING.mdoc (view with nroff | more, or  
         see pre-generated .txt and .html versions) describes the build  
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN  
         build process, are intended in the long run to replace this  
         manual update log.  
         Users building a USE_NEW_TOOLCHAIN system should read the  
         BUILDING document for caveats.  Generally, BUILDING supersedes  
         UPDATING for these systems, as tool updating is taken care of  
         by the new build system.  
         src/etc/Makefile now needs install to be able to handle  
         symlinks that point to nowhere. A bug in install that  
         prevented this was corrected.  
         Solution: update and reinstall usr.bin/xinstall  
         Better Solution: Use the new toolchain and it will just work  
         for you.  
         /etc/mtree/NetBSD.dist has been updated to take advantage of  
         absolute path support added to mtree(8). Older mtree(8)s don't  
         understand the format.  
         Solution: update and reinstall usr.sbin/mtree  
         Crunchgen has been updated to work via reach-over makefiles. Updating  
         is suggested before running a snapshot build  
         The new "ubcperf" code committed by Chuck Silvers removed  
         a header file, uvm/uvm_vnode.h.  There may be stale .depend  
         files that still reference this file.  
         Solution: "make cleandir && make dependall" in affected  
         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.  
         (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]  
         Bootloader update on ELF platforms.  DDB in kernels from before  
         this will be unable to read symbol tables provided by newer  
         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  
         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.  
         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.  
         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:  
         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.  
         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.  
         prepare the code to compile with stricter gcc flags. in  
         particular start eliminating redundant declarations. Yacc  
         needs to be installed before make build.  
         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.  
         bsd.subdir.mk committed 20001230 had a bug which caused  
         afterinstall targets to run too soon; update again.  
         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.  
         The `ca' device driver has been replaced by `ld'; although the  
         major and minor numbers haven't changed, you should update your /dev  
         The following make directives are obsoleted.  
         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}.
