 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.

         reinstall usr.sbin/config before build the kernel.  
   20080303:
 20020822:          Linker warnings are now fatal if $WARNS>0.
         Crunched rescue tools (contents of /bin and /sbin, plus others)  
         are now provided in /rescue.  20080126:

         Solution: update and reinstall usr.bin/crunch  
   20071115:
 20020515:          The it(4) driver has been renamed to itesio(4) and the old port
         sshd user/group has been added.  Need to hand add this in, or sshd          argument specified in the kernel configuration file is not valid
         will not let you log in (with default, or UsePrivlegeSeparation=yes)          anymore. The itesio(4) driver now uses the Super I/O address port

         sshd:*:16:  20071028:
           The pccons(4) driver has been removed from the NetBSD/shark port.
         and the following to /etc/master.passwd (via vipw):          You need to update any custom kernel configuration file you have
           to remove any references to pccons (which includes removing the

         NBUILDJOBS obsoleted in favor of just using -j.          enumerate interfaces was fixed.  The bug began to cause
           problems after 20070911 when the kernel's SIOCGIFCONF

         configuration from earlier systems (as far back as NetBSD 1.5).  
   20070703:
 20020320:          nbinstall has been renamed as it calls the target specific and
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.          the logic to pass down STRIP from mk been removed.  This forces
         build and install at usr.bin/xinstall before the build.          a re-installation of tools.
   
 20020319:  20070422:
         raw IPv6 socket now makes strict checking for sa_family and sa_len          The way OS emulations lookup filenames inside the emulation root

         to be changed (due to the use of "/etc" inside).          This might affect symlinks that have been added to reference outside
           the emulated root.

           example.
 20020118:  
   20070319:
         ntpd user/group has been added.  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

         ntpd:*:15:          incorrectly, and ensure that you have at least
           src/lib/libc/Makefile 1.130.
         and the following to /etc/master.passwd (via vipw):

           will allow dependencies on those files to get get rebuilt
         If you're attempting to build a snapshot on sparc64 and are getting  
         reloc errors from the toolchain groff binary this means your native  20070209:

         Use the new toolchain to build and install natively (i.e. /usr/lib)          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
           the pthread library in sync, old threaded applications should
         gnu/lib/libgcc          continue to work with an old or new kernel.  Note that named(8)
         gnu/lib/libstdc++          is the only threaded application in the base system.
   
         After this a snapshot will be able to be built.  20061214:
           Following the move of string_to_flags() and flags_to_string()
 20011201:          from the bin/ls/ sources to libutil, users doing UPDATE builds

         the various "files" files.  Bug fixes to config(8) are

 20011030:  20060814:
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
         before building libc.          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
           kernel configuration for an example.  X servers from the last
 20011029:          few years should cope.
         The new document BUILDING.mdoc (view with nroff | more, or  
         see pre-generated .txt and .html versions) describes the build  20060703:
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN          MPACPI is no more. We always configure PCI interrupts using ACPI
         build process, are intended in the long run to replace this          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
         manual update log.          to ACPI_SCANPCI. Thanks to work from fvdl.
   
         Users building a USE_NEW_TOOLCHAIN system should read the  20060627:
         BUILDING document for caveats.  Generally, BUILDING supersedes          socket(2) has changed, and its system call has been versioned.
         UPDATING for these systems, as tool updating is taken care of          For userlands with the old version of socket(2), make sure that
         by the new build system.          your kernel has 'options COMPAT_30' set, or else 'bad system call'
           errors will result.
 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}.
