 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.

         The end-user modifiable X11 configuration has been moved          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
         from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.          1. Make sure your kernel has COMPAT_50 in it. Build and install.
         Ensure that src and xsrc is up to date, and run          2. make sure build.sh completes and the binaries in a chroot work
         "make cleandir" in src/x11 before your next build.             before installing.
           3. If you don't use build.sh and you build directly to root, and
 20040426:             your build breaks in the middle, don't despair. Make sure headers

         consumers of the create and delete interface, as well as             libraries in src/lib and src/gnu/lib and install them. Once
         the dynamic discovery mechanism.  This is believed only to             the new libraries are installed, you can restart the build.

         the only effect of this should be that a sysctl binary             you'll need to bump them and rebuild them.
         built from sources dated between 2003/12/04 and 2004/03/24          5. Next time you run pwd_mkdb with the new binary, the file
         will not work on a kernel built from sources dated after             will be upgraded and it will not be backwards compatible.
         2004/04/25.  If you need a new sysctl binary but build.sh          6. The utmpx/wtmpx files have been versioned, and there is
         does not work, make sure that your revision of             a heuristic for utmp. You are better off removing the
         src/sys/sys/sysctl.h is 1.112 (or later), and then the             old files after upgrading.
         do the following:  
         cd /usr/src (or wherever your source tree is)          config(1) has been updated, and one of the files it creates -
         make USETOOLS=no includes          swapnetbsd.o - has changed format.  You need to rebuild config
         cd lib/libc          (done automatically by build.sh) and then you need to rerun
         make USETOOLS=no dependall install          config on all kernel configuration files before rebuilding those
         cd ../../sbin/sysctl          kernels.
         make USETOOLS=no dependall install  
         If you are using older sysctl binary, GNU autoconf would fail to          If you build with MKX11=no, you should remove /etc/rc.d/xdm and
         identify your machine architecture, and tries to build binary for          /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
         "unknown-unknown-netbsd20F" or something like that.  if that happens,          set and will appear as extra files for MKX11=no update builds.
         make sure to follow the above steps.  
 20040425:          On i386, various kernel options(4) in GENERIC including
         The ffs superblock issues listed below under 20040109 and 20030402          file systems have been disabled and moved into kernel modules.

         sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4          following files as well as a new GENERIC kernel:
         invocation mentioned below will continue to work and is now  
         automated by those scripts.  Note that under certain circumstances,          - build and install kernel modules from src/sys/modules
         affected filesystems upgraded to a -current kernel first before  
         upgrading their userland with the fixsb and fsck_ffs fixes may          - install the latest bootloader, which will load a module

         filesystem, so it is a good idea to repair the filesystem as soon as  
         possible.  For more details on the fixsb script, see pr install/25138.          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
 20040418:          file system module manually on the boot prompt or in the boot.cfg file.
         statfs(2) and friends have been replaced with statvfs(2). Before  
         installing a newly build userland make sure that you are running  20080827:
         a newly built kernel with COMPAT_20 set. In addition your libc          If you built and installed a libc from sources between

         anymore. Manually remove all generated .S sources and objects          Since this breaks the libc build itself, manual help is
         from the libc build directory.          needed -- lint must be disabled temporarily, e.g.:
             $ (cd lib/libc && make MKLINT=no dependall install)
         The method by which athhal-elf.o gets pulled into i386 kernel builds  20080813:
         has been changed. The file is now stored as a uuencoded file in CVS          MKDEBUG build was broken because the .depend files did not know
         and the generated Makefile will use the new .uue rules from bsd.file.mk          about .go files. You need to remove all .depend files and rebuild.
         to build it.  
         This means you must have the latest bsd.files.mk installed when          WAPBL (metadata journaling support) has been added, but at this

           and userland (fsck_ffs in particular).  Please make sure you
 20040318:          don't use a journaled filesystem with an older kernel/userland,
         A bug in the cgd(4) blowfish code was corrected, without          especially an uncleanly mounted journaled filesystem.  WAPBL
         provision of backwards compatibility, after several public          also requires the super block to be in the UFS2 format.  You
         notices over several months. Users of cgd with blowfish cipher          can use fsck_ffs -c 4 to update the superblock format.
         ONLY must dump their data before updating their kernels, and  
         recreate cgd's and restore data using the new kernel. See  20080721:
         (recent message to current-users, URL when mail-index has updated)          Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
           isn't defined.
         On acorn32, the opms and qms drivers have been withdrawn, and  20080531:
         the old wsqms driver is now called qms.  Kernel config files          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
         will need updating.  See the ones in sys/arch/acorn32/conf          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
         for examples.          utility needs to be rebuilt and reinstalled as older binaries
           won't work correctly. The following sequence of commands:
         On acorn32, the beep and sysbeep devices are no longer            $ (cd sys/sys/ && nbmake-$arch includes)
         needed, and will need to be deleted from kernel configuration            $ (cd sbin/drvctl/ && nbmake-$arch clean)
         files.            $ (cd sbin/drvctl/ && nbmake-$arch all)
 20040109:          leaves new drvctl utility in sbin/drvctl build directory.
         Compatibility for old ffs superblock layouts has been  
         added, and the restrictive fsck checks have been reenabled  20080503:
         when using those layouts.  If you have been using -current          The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         since 20030402, you may find that fsck again signals fatal  
         superblock mismatches.  To repair, make sure you have  20080521:
         an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4          For a while, unprivileged UPDATE builds would fail to

         been added to the kernel which should detect this problem.          ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
         See the following discussion for more information:          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
         http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html          If you already hit this problem, update the .mk file,
           remove ${DESTDIR}/stand/<arch>, and re-run the build.
         New binutils builds may fail due to old dependencies.  20080303:
         It's necessary to "make cleandir" to ensure that          Linker warnings are now fatal if $WARNS>0.
         the dependencies will be rebuilt correctly.  
 20031111:          The posix_fadvise system call has been changed from an assembly
         A newer mkdep is needed.  Error noting that is          stub, to a c file that calls an assembly stub. You need to
                 cc: Ambiguous abbreviation --          'rm -f posix_fadvise.* .depend' in the libc build directory to
           avoid using the old assembly stub.
         /usr/include/sys/disklabel_mbr.h was removed.  20071209:
         It's necessary to "make cleandir" to ensure that          The acpiec(4) driver has been split into two attachments. If you
         the dependencies will be rebuilt correctly.          get ACPI errors before the attachment, please update your kernel
           configuration file appropriately or see GENERIC for more details.
         A sign exension bug was fixed which set all the high bits  20071115:
         of our newly expanded ffs fs_flags.  This should only          The it(4) driver has been renamed to itesio(4) and the old port
         affect users who installed or upgraded in September of 2003.          argument specified in the kernel configuration file is not valid
         A small utility program was posted to tech-kern which          anymore. The itesio(4) driver now uses the Super I/O address port
         should fix this problem, and a warning message was added          rather than the EC address port. Please update your kernel
         to the kernel which should discover and warn about it.  See          configuration file appropriately or see GENERIC for more details.
 20030906:          The pccons(4) driver has been removed from the NetBSD/shark port.
         With the addition of siginfo support the old signal trampoline          You need to update any custom kernel configuration file you have
         code has been deprecated to COMPAT_16. Make sure that your running          to remove any references to pccons (which includes removing the
         kernel has COMPAT_16 enabled before building userland.          now useless XSERVER option) and replace them with the correct
           entries for the wscons driver.  See the GENERIC configuration file
 20030801:          for more details.
         With the new openssl, there is some header and library shuffling.  
         rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \  20070913:
         /usr/lib/libdes* before building.          A latent bug in dhclient/dhcpd that caused it to be unable to
           enumerate interfaces was fixed.  The bug began to cause
 20030703:          problems after 20070911 when the kernel's SIOCGIFCONF
         Texinfo was updated to 4.6.  To avoid failures when trying to          implementation was repaired.  From 20070529 to 20070911 racoon
         build the included texinfo files, do:          could not enumerate interfaces.  (These are noted because
           normal kernel/userspace version matching hygiene is not
         cd src/gnu/usr.bin/texinfo          sufficient to avoid this problem.)  Ensure that both kernel
         make MKINFO=no dependall install          and userland are from after 20070913.

                 make MKMAN=no dependall install  
         (untested).  20070422:
           The way OS emulations lookup filenames inside the emulation root
 20030516:          has been changed.  Rather than modify the pathname (and copy back
         Due to bugs in the export handling code, invalid export lines          to userspace) namei() and lookup() directly check the emulation
         were accepted before and caused the kernel to panic when          root. One side effect is that absolute symlinks inside the emulated
         mountd got restarted because it freed memory that had already          root file system will be relative to that file system - unless they
         been freed. This has been fixed and the kernel checks          start /../ this is useful when the emulated root is a real install
         export addresses very strictly. If you upgrade your kernel,          that has such links.
         make sure you also upgrade mountd, because if your export          This might affect symlinks that have been added to reference outside

         a.b.c or a.b or a), they will get rejected by the new kernel.  
 20030402:          The pckbc driver on sgimips IP32 has been removed. Use macekbc

         with the first alternate, because they compare too many  
         fields (even ones that aren't useful).  If possible, upgrade  20070319:

         the updated /usr/share/sendmail/README file for more  
         information.  20070209:
           The threading model was changed when the newlock2 branch
 20030117:          was merged to NetBSD-current.  If you boot with a new
         Texinfo was updated to 4.3.  To avoid failures when trying to          kernel (version 4.99.10), then you also need a new pthread
         build the included texinfo files, do:          library (/usr/lib/libpthread.so.0.7).  If you boot with
           an old kernel, then you need the old pthread library
         cd src/gnu/usr.bin/texinfo          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         make MKINFO=no dependall install          the pthread library in sync, old threaded applications should
           continue to work with an old or new kernel.  Note that named(8)
 20021223:          is the only threaded application in the base system.
         The METALOG format changed slightly, to remove the leading  
         "${DESTDIR}" from path names.  20061214:
         This only affects people building with UNPRIVED.          Following the move of string_to_flags() and flags_to_string()
         For complete safety, remove the DESTDIR entirely and          from the bin/ls/ sources to libutil, users doing UPDATE builds
         update tools/mtree, before running make build.          will need to do a "make cleandir" in
                   tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
 20021219:                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
         CVS repository layout was changed.  See the following for details                  usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         if you are using (anonymous) cvs to update your tree.                  as the installation images in distrib/
           in order to excise stale references to the old stat_flags.h header
         http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html          file in the ls sources -- stat_flags.h has been removed.
 20021219:  20061108:

         of the host system passwd(5) and group(5) databases).          does not depend on -lssp and -lssp-nonshared. You'll need to
           make clean in src/tools/gcc first to rebuild the compiler.
         The build system was modified to take advantage of  
         this option (using ${NETBSDSRCDIR}/etc), so if you  20061009:
         use USETOOLS==no, you may have to rebuild and          The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
         reinstall usr.bin/xinstall first.          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
 20021130:  20060814:
         fparseln(3) moved from libutil to libc.          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been

         If using build.sh, "cd tools/compat && make clean"  20060703:
         before rebuilding the tools.          MPACPI is no more. We always configure PCI interrupts using ACPI
           if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
 20021126:          to ACPI_SCANPCI. Thanks to work from fvdl.
         The mk.conf(5) variable SYS_INCLUDE has been deprecated,  
         including the optional "SYS_INCLUDE=symlinks" support.  20060627:

         /usr/include.          For userlands with the old version of socket(2), make sure that
           your kernel has 'options COMPAT_30' set, or else 'bad system call'
 20021121:          errors will result.
         The C run-time support files crtbegin.o and crtend.o  
         (and their companions crtbeginS.o and crtendS.o) were  
         split up, with new crti.o and crtn.o files resulting.  
         This means that libtool needs to be rebuilt once the  
         new libraries are installed.  The process of rebuilding  
         libtool will cause it to automatically notice the new  
         required files, but it *must* be rebuilt in order to  
         do this.  
         An out-of-date libtool will result in shared libraries  
         which lack _init() and _fini() routines, which means that  
         their global contructors/destructors will not be invoked.  
         A bug related to how ARM ELF objects were tagged has been  
         NetBSD ARM ELF uses the soft-VFP floating point model by  
         default.  However, the assembler lacked support for marking  
         objects as using the VFP floating point format, and the  
         compiler was not properly passing the flag indicating "soft-VFP"  
         to the assembler.  
         Unfortunately, this means that the linker will now consider  
         old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be  
         incompatible with new (properly marked) objects.  
         The problem will only manifest itself if you attempt to compile  
         a new program using the fixed toolchain, and link that program  
         against old libraries which do not have the proper "softvfp"  
         The only work-around for the problem is to recompile all of  
         the libraries on the system.  The easiest way to do this for  
         system libraries is to install a binary snapshot; they are  
         generally available on releng.NetBSD.org.  Any packages you  
         have installed which supply libraries will have to be recompiled  
         if you wish to link new programs against those libraries.  
         If you have questions about this matter, please contact  
         Systrace has been improved to support privilege elevation.  
         Updating the kernel requires the userland part of systrace  
         to be rebuilt.  
         The config(8) grammar was changed to allow options to register  
         dependencies on attributes, as well as other options.  Users  
         must update and reinstall usr.sbin/config before building a new  
         A new attribute dependency syntax was introduced to config(8),  
         which is now used by the SCSI configuration description.  Users  
         must update and reinstall usr.sbin/config before building a new  
         Several changes have been made to the autoconfiguration  
         framework.  Users must update and reinstall usr.sbin/config  
         before building a new kernel.  
         The i386mp branch has been merged.  To compile a kernel, users  
         will need to add the option 'cpu* at mainbus?' to their configuration  
         file.  Multiprocessor kernels will need  
         ioapic*         at mainbus? apid ?

         MKDYNAMICROOT=yes enabled by default, which means that  
         certain shared libraries are installed into /lib, the shared  
         linker is installed into /libexec, and all programs in /bin  
         and /sbin are dynamically linked.  
         If you do not use "make build", you should ensure that  
         you have the libraries and shared linker in the new locations,  
                 make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so  
         USE_NEW_TOOLCHAIN has been replaced with:  
             -   TOOLCHAIN_MISSING -- set to "yes" on platforms for which  
                 there is no working in-tree toolchain (hppa, ns32k, sh5,  
             -   EXTERNAL_TOOLCHAIN -- if defined by the user, points to the  
                 root of an external toolchain (e.g. /usr/local/gnu).  This  
                 enables the cross-build framework even for TOOLCHAIN_MISSING  
         gehenna-devsw has been merged into the trunk. Need to update and  
         reinstall usr.sbin/config before building the kernel.  
         Crunched rescue tools (contents of /bin and /sbin, plus others)  
         are now provided in /rescue.  
         To ensure that these are built statically linked (no matter  
         what the setting of LDSTATIC is), use a crunchgen(1) built  
         from sources newer than 20020820 (see the next entry).  
         crunchgen(1) changed to ensure that the generated program  
         is statically linked.  
         Solution: update and reinstall usr.bin/crunch  
         smmsp user/group has been added for sendmail.  
         Add the following into /etc/group:  
         and the following to /etc/master.passwd (via vipw):  
         smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin  
         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)  
         Add the following into /etc/group:  
         and the following to /etc/master.passwd (via vipw):  
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin  
         Also /var/chroot/sshd directory needs to be present (digged as part of  
         the build process).  
         NBUILDJOBS obsoleted in favor of just using -j.  
         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}.
