 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.
   
 For a more detailed description see Makefile.  See also: BUILDING, build.sh, Makefile.

 20010726:  20070703:
         Texinfo was updated to 4.0.  To avoid failures when trying to          nbinstall has been renamed as it calls the target specific and
         build the included texinfo files, use MKINFO=no before the new          the logic to pass down STRIP from mk been removed.  This forces
         makeinfo has been installed.          a re-installation of tools.
   
 20010718:  20070422:
           The way OS emulations lookup filenames inside the emulation root
         Enabled correct .init/.fini processing in crt0.  The way this          has been changed.  Rather than modify the pathname (and copy back
         was done was to change a -I directive to cc(1), which means          to userspace) namei() and lookup() directly check the emulation
         make(1) will have a stale dependency (it will be checking the          root. One side effect is that absolute symlinks inside the emulated
         timestamp on the wrong "dot_init.h").          root filesytem will be relative to that filesystem - unless they
           start /../ this is useful when the emulated root is a real install
         The symptom you will see is that new programs die with SIGSEGV          that has such links.
         if you have a stale dependency.          This might affect symlinks that have been added to reference outside
           the emulated root.
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so  
         before starting your build.  20070412:
           The pckbc driver on sgimips IP32 has been removed. Use macekbc
 20010628:          instead. See the GENERIC32_IP3x kernel configuration for an
           example.
         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  20070319:
         bitfield, update your lint(1) before proceeding.          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
           on many platforms due to incorrect flags settings.  If you
 20010226:          updated and built after about 20070315, do "nbmake-$arch
           cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
         Added named user/group to system. Need to hand add this in or builds          rebuild of object files that might have been built
         will break as mtree aborts early.          incorrectly, and ensure that you have at least
           src/lib/libc/Makefile 1.130.
         To work around add by hand:  
   20070210:
         named:*:14:          src/sys/sys/{sa.h,savar.h} were removed.
             find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
         to /etc/group and add:                | xargs egrep -l '/sa.h|/savar.h' | xargs rm
           will allow dependencies on those files to get get rebuilt
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin  
   20070209:
         to master.passwd (use vipw for instance if doing by hand).          The threading model was changed when the newlock2 branch
           was merged to NetBSD-current.  If you boot with a new
         Now a make build should progress.          kernel (version 4.99.10), then you also need a new pthread
           library (/usr/lib/libpthread.so.0.7).  If you boot with
 20010219:          an old kernel, then you need the old pthread library
         get/setprogname() added. Any hostprog's that may use this will need          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         to be bootstrapped manually until the host system is current.          the pthread library in sync, old threaded applications should
           continue to work with an old or new kernel.  Note that named(8)

                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to  
                           CFLAGS and rebuilding should work)  20061214:

           in order to excise stale references to the old stat_flags.h header
 20010114:          file in the ls sources -- stat_flags.h has been removed.

         bring everything up-to-date first, then without installing  20061108:

         with make build.          changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
 20010101:          make clean in src/tools/gcc first to rebuild the compiler.
         bsd.subdir.mk committed 20001230 had a bug which caused  
         afterinstall targets to run too soon; update again.  20061009:
           The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
 20001230:          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
         New share/mk files needed to support .WAIT in SUBDIR variables.  
         If you get make errors,  20060814:

         Also, PRINTOBJDIR has changed and is now used more heavily.          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
           kernel configuration for an example.  X servers from the last
 20001019:          few years should cope.
         The `ca' device driver has been replaced by `ld'; although the  
         major and minor numbers haven't changed, you should update your /dev  20060703:
         directory.          MPACPI is no more. We always configure PCI interrupts using ACPI
           if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
 20000929:          to ACPI_SCANPCI. Thanks to work from fvdl.
         The following make directives are obsoleted.  
         MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA  20060627:

 20000623:  
         MKCRYPTO and friends added to share/mk/bsd.own.mk.
