 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.

 20010915:  20080531:
         The new "ubcperf" code committed by Chuck Silvers removed          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
         a header file, uvm/uvm_vnode.h.  There may be stale .depend          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
         files that still reference this file.          utility needs to be rebuilt and reinstalled as older binaries
           won't work correctly. The following sequence of commands:
         Solution: "make cleandir && make dependall" in affected  
         directories.            $ (cd sys/sys/ && nbmake-$arch includes)
             $ (cd sbin/drvctl/ && nbmake-$arch clean)
 20010803:            $ (cd sbin/drvctl/ && nbmake-$arch all)
         grep.info is now built from grep.texi using makeinfo.  Since it  
         requires makeinfo v4.0, you need to install new texinfo before          leaves new drvctl utility in sbin/drvctl build directory.
         building gnu/usr.bin/grep.  To install new texinfo, please follow  
         the instruction described in 20010726 entry.  20080503:
           The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
 20010803:  
         (i386 only): i386 kernel now uses new instructions like fxsave which  20080521:
         old gas doesn't understand.  To build the kernel successfuly, you          For a while, unprivileged UPDATE builds would fail to
         need to build and install new gas (gnu/usr.bin/gas.new).          succeed at the checkflist stage, complaining that
           ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
 20010731:          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
         Bootloader update on ELF platforms.  DDB in kernels from before          If you already hit this problem, update the .mk file,
         this will be unable to read symbol tables provided by newer          remove ${DESTDIR}/stand/<arch>, and re-run the build.
         bootloaders.  
   20080126:
 20010726:          The posix_fadvise system call has been changed from an assembly
         Texinfo was updated to 4.0.  To avoid failures when trying to          stub, to a c file that calls an assembly stub. You need to
         build the included texinfo files, do:          'rm -f posix_fadvise.* .depend' in the libc build directory to
           avoid using the old assembly stub.
         cd src/gnu/usr.bin/texinfo  
         make MKINFO=no dependall install  20071209:
           The acpiec(4) driver has been split into two attachments. If you
 20010718:          get ACPI errors before the attachment, please update your kernel
           configuration file appropriately or see GENERIC for more details.
         Enabled correct .init/.fini processing in crt0.  The way this  
         was done was to change a -I directive to cc(1), which means  20071115:
         make(1) will have a stale dependency (it will be checking the          The it(4) driver has been renamed to itesio(4) and the old port
         timestamp on the wrong "dot_init.h").          argument specified in the kernel configuration file is not valid
           anymore. The itesio(4) driver now uses the Super I/O address port
         The symptom you will see is that new programs die with SIGSEGV          rather than the EC address port. Please update your kernel
         if you have a stale dependency.          configuration file appropriately or see GENERIC for more details.
   
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so  20071028:
         before starting your build.          The pccons(4) driver has been removed from the NetBSD/shark port.
           You need to update any custom kernel configuration file you have
 20010628:          to remove any references to pccons (which includes removing the
           now useless XSERVER option) and replace them with the correct
         A construct was added to uvm_page.h that uncovered a bug          entries for the wscons driver.  See the GENERIC configuration file
         in lint(1).  If you get a warning/error about a non-portable          for more details.
         bitfield, update your lint(1) before proceeding.  
   20070913:
 20010226:          A latent bug in dhclient/dhcpd that caused it to be unable to
           enumerate interfaces was fixed.  The bug began to cause
         Added named user/group to system. Need to hand add this in or builds          problems after 20070911 when the kernel's SIOCGIFCONF
         will break as mtree aborts early.          implementation was repaired.  From 20070529 to 20070911 racoon
           could not enumerate interfaces.  (These are noted because
         To work around add by hand:          normal kernel/userspace version matching hygiene is not
           sufficient to avoid this problem.)  Ensure that both kernel
         named:*:14:          and userland are from after 20070913.
   
         to /etc/group and add:  20070703:
           nbinstall has been renamed as it calls the target specific and
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin          the logic to pass down STRIP from mk been removed.  This forces
           a re-installation of tools.
         to master.passwd (use vipw for instance if doing by hand).  
   20070422:
         Now a make build should progress.          The way OS emulations lookup filenames inside the emulation root
           has been changed.  Rather than modify the pathname (and copy back
 20010219:          to userspace) namei() and lookup() directly check the emulation
         get/setprogname() added. Any hostprog's that may use this will need          root. One side effect is that absolute symlinks inside the emulated
         to be bootstrapped manually until the host system is current.          root file system will be relative to that file system - unless they
           start /../ this is useful when the emulated root is a real install
         Known problems: sys/arch/macppc/stand/fixcoff          that has such links.
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to          This might affect symlinks that have been added to reference outside
                           CFLAGS and rebuilding should work)          the emulated root.
                         usr.sbin/mdsetimage - Build a static copy if  
                           building a snapshot before fully bootstrapped.  20070412:
           The pckbc driver on sgimips IP32 has been removed. Use macekbc
 20010204:          instead. See the GENERIC32_IP3x kernel configuration for an
         prepare the code to compile with stricter gcc flags. in          example.
         particular start eliminating redundant declarations. Yacc  
         needs to be installed before make build.  20070319:
           src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
 20010114:          on many platforms due to incorrect flags settings.  If you
         introduce .if commands(target) in make(1). You need to          updated and built after about 20070315, do "nbmake-$arch
         bring everything up-to-date first, then without installing          cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
         anything make and install in usr.bin/make, then proceed          rebuild of object files that might have been built
         with make build.          incorrectly, and ensure that you have at least
           src/lib/libc/Makefile 1.130.
 20010101:  
         bsd.subdir.mk committed 20001230 had a bug which caused  20070210:
         afterinstall targets to run too soon; update again.          src/sys/sys/{sa.h,savar.h} were removed.
             find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
 20001230:                | xargs egrep -l '/sa.h|/savar.h' | xargs rm
         New share/mk files needed to support .WAIT in SUBDIR variables.          will allow dependencies on those files to get get rebuilt
         If you get make errors,  
                 (cd share/mk; make install)  20070209:
         Also, PRINTOBJDIR has changed and is now used more heavily.          The threading model was changed when the newlock2 branch
           was merged to NetBSD-current.  If you boot with a new
 20001019:          kernel (version 4.99.10), then you also need a new pthread
         The `ca' device driver has been replaced by `ld'; although the          library (/usr/lib/libpthread.so.0.7).  If you boot with
         major and minor numbers haven't changed, you should update your /dev          an old kernel, then you need the old pthread library
         directory.          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
           the pthread library in sync, old threaded applications should
 20000929:          continue to work with an old or new kernel.  Note that named(8)
         The following make directives are obsoleted.          is the only threaded application in the base system.
         MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA  
         By default, RSA is built into libcrypto.  IDEA and RC5 will not be  20061214:
         built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build          Following the move of string_to_flags() and flags_to_string()
         additional library libcrypto_{idea,rc5}.          from the bin/ls/ sources to libutil, users doing UPDATE builds
           will need to do a "make cleandir" in
 20000623:                  tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
         MKCRYPTO and friends added to share/mk/bsd.own.mk.                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
         'cd share/mk ; make install' needed before make build.                  usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
                   as the installation images in distrib/
           in order to excise stale references to the old stat_flags.h header
           file in the ls sources -- stat_flags.h has been removed.
   
   20061108:
           The configure script used in the src/tools/gcc compiler has been
           changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
           make clean in src/tools/gcc first to rebuild the compiler.
   
   20061009:
           The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
           available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
   
   20060814:
           The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
           withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
           kernel configuration for an example.  X servers from the last
           few years should cope.
   
   20060703:
           MPACPI is no more. We always configure PCI interrupts using ACPI
           if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
           to ACPI_SCANPCI. Thanks to work from fvdl.
   
   20060627:
           socket(2) has changed, and its system call has been versioned.
           For userlands with the old version of socket(2), make sure that
           your kernel has 'options COMPAT_30' set, or else 'bad system call'
           errors will result.
