 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.

 20020515:  20071115:
         sshd user/group has been added.  Need to hand add this in, or sshd          The it(4) driver has been renamed to itesio(4) and the old port
         will not let you log in (with default, or UsePrivlegeSeparation=yes)          argument specified in the kernel configuration file is not valid
           anymore. The itesio(4) driver now uses the Super I/O address port
         Add the following into /etc/group:          rather than the EC address port. Please update your kernel
           configuration file appropriately or see GENERIC for more details.
         sshd:*:16:  
   20071028:
         and the following to /etc/master.passwd (via vipw):          The pccons(4) driver has been removed from the NetBSD/shark port.
           You need to update any custom kernel configuration file you have
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin          to remove any references to pccons (which includes removing the
           now useless XSERVER option) and replace them with the correct
         also /var/chroot/sshd directory needs to be present (digged as a part of          entries for the wscons driver.  See the GENERIC configuration file
         build process).          for more details.
   
 20020426:  20070913:
         NBUILDJOBS obsoleted in favor of just using -j.          A latent bug in dhclient/dhcpd that caused it to be unable to
           enumerate interfaces was fixed.  The bug began to cause
 20020426:          problems after 20070911 when the kernel's SIOCGIFCONF
         etc/postinstall added, which performs various checks for          implementation was repaired.  From 20070529 to 20070911 racoon
         configuration file updates and changes, and can fix most of          could not enumerate interfaces.  (These are noted because
         the problems identified.          normal kernel/userspace version matching hygiene is not
         This should make it much easier to upgrade a system's          sufficient to avoid this problem.)  Ensure that both kernel
         configuration from earlier systems (as far back as NetBSD 1.5).          and userland are from after 20070913.
   
 20020320:  20070703:
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.          nbinstall has been renamed as it calls the target specific and
         build and install at usr.bin/xinstall before the build.          the logic to pass down STRIP from mk been removed.  This forces
           a re-installation of tools.
 20020319:  
         raw IPv6 socket now makes strict checking for sa_family and sa_len  20070422:
         on send(2) operation.  be sure to have sbin/rtsol and usr.sbin/rtsold          The way OS emulations lookup filenames inside the emulation root
         newer than November 2001 when you upgrade the kernel.          has been changed.  Rather than modify the pathname (and copy back
           to userspace) namei() and lookup() directly check the emulation
 20020311:          root. One side effect is that absolute symlinks inside the emulated
         ssh configuration files were moved from /etc to /etc/ssh.  Beware          root file system will be relative to that file system - unless they
         if you restart your machine from remote.  Note that sshd.conf needs          start /../ this is useful when the emulated root is a real install
         to be changed (due to the use of "/etc" inside).          that has such links.
           This might affect symlinks that have been added to reference outside
 20020223:          the emulated root.
         Users of the VAX port will need to rebuild and install gas  
         so it deal with the now present register prefix used in all  20070412:
         the VAX assembly files.          The pckbc driver on sgimips IP32 has been removed. Use macekbc
           instead. See the GENERIC32_IP3x kernel configuration for an
 20020118:          example.
   
         ntpd user/group has been added.  Need to hand add this in or builds  20070319:
         will break as mtree aborts early.          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
           on many platforms due to incorrect flags settings.  If you
         Add the following into /etc/group:          updated and built after about 20070315, do "nbmake-$arch
           cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
         ntpd:*:15:          rebuild of object files that might have been built
           incorrectly, and ensure that you have at least
         and the following to /etc/master.passwd (via vipw):          src/lib/libc/Makefile 1.130.
   
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin  20070210:
           src/sys/sys/{sa.h,savar.h} were removed.
 20011207:            find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
                 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
         If you're attempting to build a snapshot on sparc64 and are getting          will allow dependencies on those files to get get rebuilt
         reloc errors from the toolchain groff binary this means your native  
         toolchain has some broken C++ bits.  20070209:
           The threading model was changed when the newlock2 branch
         To fix:          was merged to NetBSD-current.  If you boot with a new
           kernel (version 4.99.10), then you also need a new pthread
         Build a new toolchain (i.e. build.sh -t)          library (/usr/lib/libpthread.so.0.7).  If you boot with
         Use the new toolchain to build and install natively (i.e. /usr/lib)          an old kernel, then you need the old pthread library
           (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         gnu/lib/libgcc          the pthread library in sync, old threaded applications should
         gnu/lib/libstdc++          continue to work with an old or new kernel.  Note that named(8)
           is the only threaded application in the base system.
         After this a snapshot will be able to be built.  
   20061214:
 20011201:          Following the move of string_to_flags() and flags_to_string()
         In order for a sparc64 build to work you must have a working awk. If          from the bin/ls/ sources to libutil, users doing UPDATE builds
         you've built and installed a system with the new toolchain up to this          will need to do a "make cleandir" in
         point you do not have a working awk as its ability to do floating                  tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
         point is broken.                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
                   usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         To build:                  as the installation images in distrib/
           in order to excise stale references to the old stat_flags.h header
         remake and install gnu/lib/libgcc          file in the ls sources -- stat_flags.h has been removed.
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links  
         against the new libgcc.a)  20061108:
           The configure script used in the src/tools/gcc compiler has been
 20011128:          changed to indicate that our libc has ssp support built-in and
         Kernel config information was changed to use defflag in          does not depend on -lssp and -lssp-nonshared. You'll need to
         the various "files" files.  Bug fixes to config(8) are          make clean in src/tools/gcc first to rebuild the compiler.
         required in order for this to work properly.  Make sure  
         to build and install in usr.sbin/config before attempting  20061009:
         to build a new kernel.          The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
           available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
 20011030:  
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)  20060814:
         before building libc.          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
           withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
 20011029:          kernel configuration for an example.  X servers from the last
         The new document BUILDING.mdoc (view with nroff | more, or          few years should cope.
         see pre-generated .txt and .html versions) describes the build  
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN  20060703:
         build process, are intended in the long run to replace this          MPACPI is no more. We always configure PCI interrupts using ACPI
         manual update log.          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
           to ACPI_SCANPCI. Thanks to work from fvdl.
         Users building a USE_NEW_TOOLCHAIN system should read the  
         BUILDING document for caveats.  Generally, BUILDING supersedes  20060627:
         UPDATING for these systems, as tool updating is taken care of          socket(2) has changed, and its system call has been versioned.
         by the new build system.          For userlands with the old version of socket(2), make sure that
           your kernel has 'options COMPAT_30' set, or else 'bad system call'
 20011028:          errors will result.
         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}.
