 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.

 20020320:  20090110:
         <bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
         build and install at usr.bin/xinstall before the build.          1. Make sure your kernel has COMPAT_50 in it. Build and install.
              This is needed even in the MODULAR kernel because there is
 20020319:             conditionally compiled code in rtsock.c.
         raw IPv6 socket now makes strict checking for sa_family and sa_len          2. make sure build.sh completes and the binaries in a chroot work
         on send(2) operation.  be sure to have sbin/rtsol and usr.sbin/rtsold             before installing.
         newer than November 2001 when you upgrade the kernel.          3. If you don't use build.sh and you build directly to root, and
              your build breaks in the middle, don't despair. Make sure headers
 20020311:             are installed properly, and start building libraries first libc
         ssh configuration files were moved from /etc to /etc/ssh.  Beware             and libutil, install them and then continue building all the
         if you restart your machine from remote.  Note that sshd.conf needs             libraries in src/lib and src/gnu/lib and install them. Once
         to be changed (due to the use of "/etc" inside).             the new libraries are installed, you can restart the build.
           4. If you compile packages and you notice link time warnings,
 20020223:             you'll need to bump them and rebuild them.
         Users of the VAX port will need to rebuild and install gas          5. Next time you run pwd_mkdb with the new binary, the file
         so it deal with the now present register prefix used in all             will be upgraded and it will not be backwards compatible.
         the VAX assembly files.          6. The utmpx/wtmpx files have been versioned, and there is
              a heuristic for utmp. You are better off removing the
 20020118:             old files after upgrading. The accounting file has not
              been versioned, and will need to be removed.
         ntpd user/group has been added.  Need to hand add this in or builds  
         will break as mtree aborts early.  20081219:
           config(1) has been updated, and one of the files it creates -
         Add the following into /etc/group:          swapnetbsd.o - has changed format.  You need to rebuild config
           (done automatically by build.sh) and then you need to rerun
         ntpd:*:15:          config on all kernel configuration files before rebuilding those
           kernels.
         and the following to /etc/master.passwd (via vipw):  
   20081205:
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin          If you build with MKX11=no, you should remove /etc/rc.d/xdm and
           /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
 20011207:          set and will appear as extra files for MKX11=no update builds.

         toolchain has some broken C++ bits.          file systems have been disabled and moved into kernel modules.
           Before trying a new GENERIC kernel, you have to prepare the
         To fix:          following files as well as a new GENERIC kernel:
   
         Build a new toolchain (i.e. build.sh -t)          - build and install kernel modules from src/sys/modules
         Use the new toolchain to build and install natively (i.e. /usr/lib)  
           - install the latest bootloader, which will load a module
         gnu/lib/libgcc            for the file system from which the kernel is loaded automatically
         gnu/lib/libstdc++  
           If you have to load your kernel from a file system which is not of
         After this a snapshot will be able to be built.          the same type as the root file system, you have to load the necessary
           file system module manually on the boot prompt or in the boot.cfg file.
 20011201:  
         In order for a sparc64 build to work you must have a working awk. If  20080827:
         you've built and installed a system with the new toolchain up to this          If you built and installed a libc from sources between

         point is broken.          which results in false errors reported by lint(1).
           Since this breaks the libc build itself, manual help is
         To build:          needed -- lint must be disabled temporarily, e.g.:
             $ (cd lib/libc && make MKLINT=no dependall install)
         remake and install gnu/lib/libgcc  
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links  20080813:
         against the new libgcc.a)          MKDEBUG build was broken because the .depend files did not know
           about .go files. You need to remove all .depend files and rebuild.
 20011128:  
         Kernel config information was changed to use defflag in  20080731:
         the various "files" files.  Bug fixes to config(8) are          WAPBL (metadata journaling support) has been added, but at this

         to build a new kernel.          don't use a journaled filesystem with an older kernel/userland,
           especially an uncleanly mounted journaled filesystem.  WAPBL
 20011030:          also requires the super block to be in the UFS2 format.  You
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)          can use fsck_ffs -c 4 to update the superblock format.
         before building libc.  
   20080721:
 20011029:          Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
         The new document BUILDING.mdoc (view with nroff | more, or          isn't defined.
         see pre-generated .txt and .html versions) describes the build  
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN  20080531:

         symlinks that point to nowhere. A bug in install that  
         prevented this was corrected.  20080503:
           The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         Solution: update and reinstall usr.bin/xinstall  
         Better Solution: Use the new toolchain and it will just work  20080521:
         for you.          For a while, unprivileged UPDATE builds would fail to

         /etc/mtree/NetBSD.dist has been updated to take advantage of          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
         absolute path support added to mtree(8). Older mtree(8)s don't          If you already hit this problem, update the .mk file,
         understand the format.          remove ${DESTDIR}/stand/<arch>, and re-run the build.
   
         Solution: update and reinstall usr.sbin/mtree  20080303:
           Linker warnings are now fatal if $WARNS>0.
 20011004:  
         Crunchgen has been updated to work via reach-over makefiles. Updating  20080126:
         is suggested before running a snapshot build          The posix_fadvise system call has been changed from an assembly

         a header file, uvm/uvm_vnode.h.  There may be stale .depend  
         files that still reference this file.  20071209:
           The acpiec(4) driver has been split into two attachments. If you

         directories.          configuration file appropriately or see GENERIC for more details.
   
 20010803:  20071115:
         grep.info is now built from grep.texi using makeinfo.  Since it          The it(4) driver has been renamed to itesio(4) and the old port
         requires makeinfo v4.0, you need to install new texinfo before          argument specified in the kernel configuration file is not valid
         building gnu/usr.bin/grep.  To install new texinfo, please follow          anymore. The itesio(4) driver now uses the Super I/O address port
         the instruction described in 20010726 entry.          rather than the EC address port. Please update your kernel
           configuration file appropriately or see GENERIC for more details.
 20010803:

         kernel successfully, you need to build and install new gas          You need to update any custom kernel configuration file you have
         (gnu/usr.bin/gas.new), or (temporarily) comment out          to remove any references to pccons (which includes removing the

         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

   20070319:
         To work around add by hand:          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
           on many platforms due to incorrect flags settings.  If you

         to be bootstrapped manually until the host system is current.  20070209:
           The threading model was changed when the newlock2 branch
         Known problems: sys/arch/macppc/stand/fixcoff          was merged to NetBSD-current.  If you boot with a new
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to          kernel (version 4.99.10), then you also need a new pthread
