 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.

 20030516:  20090110:
         Due to bugs in the export handling code, invalid export lines          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
         were accepted before and caused the kernel to panic when          1. Make sure your kernel has COMPAT_50 in it. Build and install.
         mountd got restarted because it freed memory that had already          2. make sure build.sh completes and the binaries in a chroot work
         been freed. This has been fixed and the kernel checks             before installing.
         export addresses very strictly. If you upgrade your kernel,          3. If you don't use build.sh and you build directly to root, and
         make sure you also upgrade mountd, because if your export             your build breaks in the middle, don't despair. Make sure headers
         file contains lines with an old inet4 address syntax (i.e.             are installed properly, and start building libraries first libc
         a.b.c or a.b or a), they will get rejected by the new kernel.             and libutil, install them and then continue building all the
              libraries in src/lib and src/gnu/lib and install them. Once
 20030402:             the new libraries are installed, you can restart the build.
         The superblock layout for FFS was changed.  If you have 1.6          4. If you compile packages and you notice link time warnings,
         fsck binaries, they will signal a fatal superblock mismatch             you'll need to bump them and rebuild them.
         with the first alternate, because they compare too many          5. Next time you run pwd_mkdb with the new binary, the file
         fields (even ones that aren't useful).  If possible, upgrade             will be upgraded and it will not be backwards compatible.
         your fsck_ffs binary before using a new kernel.          6. The utmpx/wtmpx files have been versioned, and there is
         None of this signals actual filesystem damage.             a heuristic for utmp. You are better off removing the
              old files after upgrading.
 20030324:  
         sendmail version 8.12.8 was imported.  Since sendmail is  20081219:
         now setgid to the smmsp group, and runs in "collection"          config(1) has been updated, and one of the files it creates -
         mode for most common activities, there is a new config          swapnetbsd.o - has changed format.  You need to rebuild config
         file called submit.cf that needs to live in /etc/mail.          (done automatically by build.sh) and then you need to rerun
         The generic submit.cf sample in /usr/share/sendmail/cf          config on all kernel configuration files before rebuilding those
         is named netbsd-msp.cf.  Upgrading your regular sendmail          kernels.
         configuration file is also strongly advised.  
   20081205:
         See the section named "MESSAGE SUBMISSION PROGRAM" in          If you build with MKX11=no, you should remove /etc/rc.d/xdm and
         the updated /usr/share/sendmail/README file for more          /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
         information.          set and will appear as extra files for MKX11=no update builds.
   
 20030117:  20081122:
         Texinfo was updated to 4.3.  To avoid failures when trying to          On i386, various kernel options(4) in GENERIC including
         build the included texinfo files, do:          file systems have been disabled and moved into kernel modules.
           Before trying a new GENERIC kernel, you have to prepare the
         cd src/gnu/usr.bin/texinfo          following files as well as a new GENERIC kernel:
         make MKINFO=no dependall install  
           - build and install kernel modules from src/sys/modules
 20021223:  
         The METALOG format changed slightly, to remove the leading          - install the latest bootloader, which will load a module
         "${DESTDIR}" from path names.            for the file system from which the kernel is loaded automatically
         This only affects people building with UNPRIVED.  
         For complete safety, remove the DESTDIR entirely and          If you have to load your kernel from a file system which is not of
         update tools/mtree, before running make build.          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.
 20021219:  
         CVS repository layout was changed.  See the following for details  20080827:
         if you are using (anonymous) cvs to update your tree.          If you built and installed a libc from sources between
           2008/08/20 and 2008/08/26 you got a broken strtouq(3)
         http://mail-index.netbsd.org/netbsd-announce/2002/12/19/0000.html          which results in false errors reported by lint(1).
           Since this breaks the libc build itself, manual help is
 20021219:          needed -- lint must be disabled temporarily, e.g.:
         install(1) had a '-N dbdir' option added, to specify an            $ (cd lib/libc && make MKLINT=no dependall install)
         alternate location to look up users & groups (instead  
         of the host system passwd(5) and group(5) databases).  20080813:
           MKDEBUG build was broken because the .depend files did not know
         The build system was modified to take advantage of          about .go files. You need to remove all .depend files and rebuild.
         this option (using ${NETBSDSRCDIR}/etc), so if you  
         use USETOOLS==no, you may have to rebuild and  20080731:
         reinstall usr.bin/xinstall first.          WAPBL (metadata journaling support) has been added, but at this
           time isn't backwards compatible with pre-WAPBL aware kernels
 20021130:          and userland (fsck_ffs in particular).  Please make sure you
         fparseln(3) moved from libutil to libc.          don't use a journaled filesystem with an older kernel/userland,
         If building to DESTDIR=/, reinstall the includes          especially an uncleanly mounted journaled filesystem.  WAPBL
         and rebuild libc:          also requires the super block to be in the UFS2 format.  You
                 make includes          can use fsck_ffs -c 4 to update the superblock format.
                 make do-lib-libc  
         If using build.sh, "cd tools/compat && make clean"  20080721:
         before rebuilding the tools.          Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
           isn't defined.
 20021126:  
         The mk.conf(5) variable SYS_INCLUDE has been deprecated,  20080531:
         including the optional "SYS_INCLUDE=symlinks" support.          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
         All header files, including <sys/*.h> are copied into          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
         /usr/include.          utility needs to be rebuilt and reinstalled as older binaries
           won't work correctly. The following sequence of commands:
 20021121:  
         The C run-time support files crtbegin.o and crtend.o            $ (cd sys/sys/ && nbmake-$arch includes)
         (and their companions crtbeginS.o and crtendS.o) were            $ (cd sbin/drvctl/ && nbmake-$arch clean)
         split up, with new crti.o and crtn.o files resulting.            $ (cd sbin/drvctl/ && nbmake-$arch all)
         This means that libtool needs to be rebuilt once the  
         new libraries are installed.  The process of rebuilding          leaves new drvctl utility in sbin/drvctl build directory.
         libtool will cause it to automatically notice the new  
         required files, but it *must* be rebuilt in order to  20080503:
         do this.          The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
   
         An out-of-date libtool will result in shared libraries  20080521:
         which lack _init() and _fini() routines, which means that          For a while, unprivileged UPDATE builds would fail to
         their global contructors/destructors will not be invoked.          succeed at the checkflist stage, complaining that
           ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
 20021121:          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
         A bug related to how ARM ELF objects were tagged has been          If you already hit this problem, update the .mk file,
         corrected.          remove ${DESTDIR}/stand/<arch>, and re-run the build.
   
         NetBSD ARM ELF uses the soft-VFP floating point model by  20080303:
         default.  However, the assembler lacked support for marking          Linker warnings are now fatal if $WARNS>0.
         objects as using the VFP floating point format, and the  
         compiler was not properly passing the flag indicating "soft-VFP"  20080126:
         to the assembler.          The posix_fadvise system call has been changed from an assembly
           stub, to a c file that calls an assembly stub. You need to
         Unfortunately, this means that the linker will now consider          'rm -f posix_fadvise.* .depend' in the libc build directory to
         old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be          avoid using the old assembly stub.
         incompatible with new (properly marked) objects.  
   20071209:
         The problem will only manifest itself if you attempt to compile          The acpiec(4) driver has been split into two attachments. If you
         a new program using the fixed toolchain, and link that program          get ACPI errors before the attachment, please update your kernel

         markings.  ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES  
         WILL CONTINUE TO WORK PROPERLY.  20071115:
           The it(4) driver has been renamed to itesio(4) and the old port
         The only work-around for the problem is to recompile all of          argument specified in the kernel configuration file is not valid
         the libraries on the system.  The easiest way to do this for          anymore. The itesio(4) driver now uses the Super I/O address port
         system libraries is to install a binary snapshot; they are          rather than the EC address port. Please update your kernel
         generally available on releng.netbsd.org.  Any packages you          configuration file appropriately or see GENERIC for more details.
         have installed which supply libraries will have to be recompiled  
         if you wish to link new programs against those libraries.  20071028:
           The pccons(4) driver has been removed from the NetBSD/shark port.
         If you have questions about this matter, please contact          You need to update any custom kernel configuration file you have
         port-arm@netbsd.org.          to remove any references to pccons (which includes removing the
           now useless XSERVER option) and replace them with the correct
 20021011:          entries for the wscons driver.  See the GENERIC configuration file
         Systrace has been improved to support privilege elevation.          for more details.
         Updating the kernel requires the userland part of systrace  
         to be rebuilt.  20070913:
           A latent bug in dhclient/dhcpd that caused it to be unable to
 20021010:          enumerate interfaces was fixed.  The bug began to cause
         The config(8) grammar was changed to allow options to register          problems after 20070911 when the kernel's SIOCGIFCONF
         dependencies on attributes, as well as other options.  Users          implementation was repaired.  From 20070529 to 20070911 racoon

         kernel.          normal kernel/userspace version matching hygiene is not
           sufficient to avoid this problem.)  Ensure that both kernel
 20021009:          and userland are from after 20070913.
         A new attribute dependency syntax was introduced to config(8),  
         which is now used by the SCSI configuration description.  Users  20070703:
         must update and reinstall usr.sbin/config before building a new          nbinstall has been renamed as it calls the target specific and
         kernel.          the logic to pass down STRIP from mk been removed.  This forces
           a re-installation of tools.
 20021003:  
         Several changes have been made to the autoconfiguration  20070422:
         framework.  Users must update and reinstall usr.sbin/config          The way OS emulations lookup filenames inside the emulation root
         before building a new kernel.          has been changed.  Rather than modify the pathname (and copy back
           to userspace) namei() and lookup() directly check the emulation

         The i386mp branch has been merged.  To compile a kernel, users          root file system will be relative to that file system - unless they
         will need to add the option 'cpu* at mainbus?' to their configuration          start /../ this is useful when the emulated root is a real install

         certain shared libraries are installed into /lib, the shared          example.
         linker is installed into /libexec, and all programs in /bin  
         and /sbin are dynamically linked.  20070319:
         If you do not use "make build", you should ensure that          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
         you have the libraries and shared linker in the new locations,          on many platforms due to incorrect flags settings.  If you

         USE_NEW_TOOLCHAIN has been replaced with:          src/lib/libc/Makefile 1.130.
             -   TOOLCHAIN_MISSING -- set to "yes" on platforms for which  
                 there is no working in-tree toolchain (hppa, ns32k, sh5,  20070210:
                 x86_64).          src/sys/sys/{sa.h,savar.h} were removed.
             -   EXTERNAL_TOOLCHAIN -- if defined by the user, points to the            find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \

                 enables the cross-build framework even for TOOLCHAIN_MISSING          will allow dependencies on those files to get get rebuilt
                 platforms.  
   20070209:
 20020906:          The threading model was changed when the newlock2 branch
         gehenna-devsw has been merged into the trunk. Need to update and          was merged to NetBSD-current.  If you boot with a new
         reinstall usr.sbin/config before building the kernel.          kernel (version 4.99.10), then you also need a new pthread
           library (/usr/lib/libpthread.so.0.7).  If you boot with
 20020822:          an old kernel, then you need the old pthread library
         Crunched rescue tools (contents of /bin and /sbin, plus others)          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         are now provided in /rescue.          the pthread library in sync, old threaded applications should
           continue to work with an old or new kernel.  Note that named(8)
         To ensure that these are built statically linked (no matter          is the only threaded application in the base system.
         what the setting of LDSTATIC is), use a crunchgen(1) built  
         from sources newer than 20020820 (see the next entry).  20061214:
           Following the move of string_to_flags() and flags_to_string()
 20020820:          from the bin/ls/ sources to libutil, users doing UPDATE builds
         crunchgen(1) changed to ensure that the generated program          will need to do a "make cleandir" in
         is statically linked.                  tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
                   bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
         Solution: update and reinstall usr.bin/crunch                  usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
                   as the installation images in distrib/
 20020605:          in order to excise stale references to the old stat_flags.h header
         smmsp user/group has been added for sendmail.          file in the ls sources -- stat_flags.h has been removed.
   
         Add the following into /etc/group:  20061108:
           The configure script used in the src/tools/gcc compiler has been
         smmsp:*:17:          changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
         and the following to /etc/master.passwd (via vipw):          make clean in src/tools/gcc first to rebuild the compiler.
   
         smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin  20061009:
           The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
 20020515:          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
         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)  20060814:
           The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
         Add the following into /etc/group:          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
           kernel configuration for an example.  X servers from the last
         sshd:*:16:          few years should cope.
   
         and the following to /etc/master.passwd (via vipw):  20060703:
           MPACPI is no more. We always configure PCI interrupts using ACPI
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
           to ACPI_SCANPCI. Thanks to work from fvdl.
         Also /var/chroot/sshd directory needs to be present (digged as part of  
         the build process).  20060627:
           socket(2) has changed, and its system call has been versioned.
 20020426:          For userlands with the old version of socket(2), make sure that
         NBUILDJOBS obsoleted in favor of just using -j.          your kernel has 'options COMPAT_30' set, or else 'bad system call'
           errors will result.
 20020426:  
         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).  
   
 20020320:  
         <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.  
         Build and install at usr.bin/xinstall before the build.  
   
 20020319:  
         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.  
   
 20020311:  
         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).  
   
 20020223:  
         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.  
   
 20020118:  
         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:  
   
         ntpd:*:15:  
   
         and the following to /etc/master.passwd (via vipw):  
   
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin  
   
 20011207:  
         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)  
   
         gnu/lib/libgcc  
         gnu/lib/libstdc++  
   
         After this a snapshot will be able to be built.  
   
 20011201:  
         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)  
   
 20011128:  
         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.  
   
 20011030:  
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)  
         before building libc.  
   
 20011029:  
         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.  
   
 20011028:  
         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.  
   
 20011006:  
         /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  
   
 20011004:  
         Crunchgen has been updated to work via reach-over makefiles. Updating  
         is suggested before running a snapshot build  
   
 20010915:  
         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  
         directories.  
   
 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}.
