 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:  20071209:
         The new "ubcperf" code committed by Chuck Silvers removed          The acpiec(4) driver has been split into two attachments. If you

         files that still reference this file.          configuration file appropiately or see GENERIC for more details.
   
         Solution: "make cleandir && make dependall" in affected  20071115:
         directories.          The it(4) driver has been renamed to itesio(4) and the old port
           argument specified in the kernel configuration file is not valid
 20010803:          anymore. The itesio(4) driver now uses the Super I/O address port
         grep.info is now built from grep.texi using makeinfo.  Since it          rather than the EC address port. Please update your kernel
         requires makeinfo v4.0, you need to install new texinfo before          configuration file appropriately or see GENERIC for more details.
         building gnu/usr.bin/grep.  To install new texinfo, please follow  
         the instruction described in 20010726 entry.  20071028:
           The pccons(4) driver has been removed from the NetBSD/shark port.
 20010803:          You need to update any custom kernel configuration file you have
         (i386 only): i386 kernel now uses new instructions like fxsave which          to remove any references to pccons (which includes removing the
         old gas doesn't understand.  To build the kernel successfuly, you          now useless XSERVER option) and replace them with the correct
         need to build and install new gas (gnu/usr.bin/gas.new).          entries for the wscons driver.  See the GENERIC configuration file
           for more details.
 20010731:  
         Bootloader update on ELF platforms.  DDB in kernels from before  20070913:
         this will be unable to read symbol tables provided by newer          A latent bug in dhclient/dhcpd that caused it to be unable to
         bootloaders.          enumerate interfaces was fixed.  The bug began to cause
           problems after 20070911 when the kernel's SIOCGIFCONF
 20010726:          implementation was repaired.  From 20070529 to 20070911 racoon
         Texinfo was updated to 4.0.  To avoid failures when trying to          could not enumerate interfaces.  (These are noted because
         build the included texinfo files, do:          normal kernel/userspace version matching hygiene is not
           sufficient to avoid this problem.)  Ensure that both kernel
         cd src/gnu/usr.bin/texinfo          and userland are from after 20070913.
         make MKINFO=no dependall install  
   20070703:
 20010718:          nbinstall has been renamed as it calls the target specific and
           the logic to pass down STRIP from mk been removed.  This forces
         Enabled correct .init/.fini processing in crt0.  The way this          a re-installation of tools.
         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  20070422:
         timestamp on the wrong "dot_init.h").          The way OS emulations lookup filenames inside the emulation root
           has been changed.  Rather than modify the pathname (and copy back
         The symptom you will see is that new programs die with SIGSEGV          to userspace) namei() and lookup() directly check the emulation
         if you have a stale dependency.          root. One side effect is that absolute symlinks inside the emulated
           root file system will be relative to that file system - unless they

         before starting your build.          that has such links.
           This might affect symlinks that have been added to reference outside
 20010628:          the emulated root.
   
         A construct was added to uvm_page.h that uncovered a bug  20070412:
         in lint(1).  If you get a warning/error about a non-portable          The pckbc driver on sgimips IP32 has been removed. Use macekbc
         bitfield, update your lint(1) before proceeding.          instead. See the GENERIC32_IP3x kernel configuration for an
           example.
 20010226:  
   20070319:
         Added named user/group to system. Need to hand add this in or builds          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
         will break as mtree aborts early.          on many platforms due to incorrect flags settings.  If you
           updated and built after about 20070315, do "nbmake-$arch
         To work around add by hand:          cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
           rebuild of object files that might have been built
         named:*:14:          incorrectly, and ensure that you have at least
           src/lib/libc/Makefile 1.130.
         to /etc/group and add:  
   20070210:
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin          src/sys/sys/{sa.h,savar.h} were removed.
             find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
         to master.passwd (use vipw for instance if doing by hand).                | xargs egrep -l '/sa.h|/savar.h' | xargs rm
           will allow dependencies on those files to get get rebuilt
         Now a make build should progress.  
   20070209:
 20010219:          The threading model was changed when the newlock2 branch
         get/setprogname() added. Any hostprog's that may use this will need          was merged to NetBSD-current.  If you boot with a new
         to be bootstrapped manually until the host system is current.          kernel (version 4.99.10), then you also need a new pthread
           library (/usr/lib/libpthread.so.0.7).  If you boot with
         Known problems: sys/arch/macppc/stand/fixcoff          an old kernel, then you need the old pthread library
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
                           CFLAGS and rebuilding should work)          the pthread library in sync, old threaded applications should
                         usr.sbin/mdsetimage - Build a static copy if          continue to work with an old or new kernel.  Note that named(8)
                           building a snapshot before fully bootstrapped.          is the only threaded application in the base system.
   
 20010204:  20061214:
         prepare the code to compile with stricter gcc flags. in          Following the move of string_to_flags() and flags_to_string()
         particular start eliminating redundant declarations. Yacc          from the bin/ls/ sources to libutil, users doing UPDATE builds
         needs to be installed before make build.          will need to do a "make cleandir" in
                   tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
 20010114:                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
         introduce .if commands(target) in make(1). You need to                  usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         bring everything up-to-date first, then without installing                  as the installation images in distrib/
         anything make and install in usr.bin/make, then proceed          in order to excise stale references to the old stat_flags.h header
         with make build.          file in the ls sources -- stat_flags.h has been removed.
   
 20010101:  20061108:
         bsd.subdir.mk committed 20001230 had a bug which caused          The configure script used in the src/tools/gcc compiler has been
         afterinstall targets to run too soon; update again.          changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
 20001230:          make clean in src/tools/gcc first to rebuild the compiler.
         New share/mk files needed to support .WAIT in SUBDIR variables.  
         If you get make errors,  20061009:
                 (cd share/mk; make install)          The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
         Also, PRINTOBJDIR has changed and is now used more heavily.          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
   
 20001019:  20060814:
         The `ca' device driver has been replaced by `ld'; although the          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
         major and minor numbers haven't changed, you should update your /dev          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         directory.          kernel configuration for an example.  X servers from the last
           few years should cope.
 20000929:  
         The following make directives are obsoleted.  20060703:
         MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA          MPACPI is no more. We always configure PCI interrupts using ACPI
         By default, RSA is built into libcrypto.  IDEA and RC5 will not be          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
         built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build          to ACPI_SCANPCI. Thanks to work from fvdl.
         additional library libcrypto_{idea,rc5}.  
   20060627:
 20000623:          socket(2) has changed, and its system call has been versioned.
         MKCRYPTO and friends added to share/mk/bsd.own.mk.          For userlands with the old version of socket(2), make sure that
         'cd share/mk ; make install' needed before make build.          your kernel has 'options COMPAT_30' set, or else 'bad system call'
           errors will result.
