 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.

         configuration from earlier systems (as far back as NetBSD 1.5).          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

              the new libraries are installed, you can restart the build.
 20020319:          4. If you compile packages and you notice link time warnings,
         raw IPv6 socket now makes strict checking for sa_family and sa_len             you'll need to bump them and rebuild them.

           6. The utmpx/wtmpx files have been versioned, and there is

         ssh configuration files were moved from /etc to /etc/ssh.  Beware             old files after upgrading.
         if you restart your machine from remote.  Note that sshd.conf needs  
         to be changed (due to the use of "/etc" inside).  20081219:
           config(1) has been updated, and one of the files it creates -
 20020223:          swapnetbsd.o - has changed format.  You need to rebuild config
         Users of the VAX port will need to rebuild and install gas          (done automatically by build.sh) and then you need to rerun

         the VAX assembly files.          kernels.
   
 20020118:  20081205:
           If you build with MKX11=no, you should remove /etc/rc.d/xdm and

         Add the following into /etc/group:  20081122:
           On i386, various kernel options(4) in GENERIC including
         ntpd:*:15:          file systems have been disabled and moved into kernel modules.
           Before trying a new GENERIC kernel, you have to prepare the
         and the following to /etc/master.passwd (via vipw):          following files as well as a new GENERIC kernel:
   
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin          - build and install kernel modules from src/sys/modules
   
 20011207:          - install the latest bootloader, which will load a module

           file system module manually on the boot prompt or in the boot.cfg file.
         To fix:  
   20080827:
         Build a new toolchain (i.e. build.sh -t)          If you built and installed a libc from sources between
         Use the new toolchain to build and install natively (i.e. /usr/lib)          2008/08/20 and 2008/08/26 you got a broken strtouq(3)
           which results in false errors reported by lint(1).
         gnu/lib/libgcc          Since this breaks the libc build itself, manual help is
         gnu/lib/libstdc++          needed -- lint must be disabled temporarily, e.g.:
             $ (cd lib/libc && make MKLINT=no dependall install)
         After this a snapshot will be able to be built.  
   20080813:
 20011201:          MKDEBUG build was broken because the .depend files did not know
         In order for a sparc64 build to work you must have a working awk. If          about .go files. You need to remove all .depend files and rebuild.
         you've built and installed a system with the new toolchain up to this  
         point you do not have a working awk as its ability to do floating  20080731:
         point is broken.          WAPBL (metadata journaling support) has been added, but at this
           time isn't backwards compatible with pre-WAPBL aware kernels
         To build:          and userland (fsck_ffs in particular).  Please make sure you
           don't use a journaled filesystem with an older kernel/userland,
         remake and install gnu/lib/libgcc          especially an uncleanly mounted journaled filesystem.  WAPBL

         to build and install in usr.sbin/config before attempting  20080531:
         to build a new kernel.          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
           from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)

         libc/locale/wcstod.c now needs new lint(1). Update lint(1)          won't work correctly. The following sequence of commands:

         manual update log.  20080503:
           The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         Users building a USE_NEW_TOOLCHAIN system should read the  
         BUILDING document for caveats.  Generally, BUILDING supersedes  20080521:

   20080303:
         Solution: update and reinstall usr.bin/xinstall          Linker warnings are now fatal if $WARNS>0.
         Better Solution: Use the new toolchain and it will just work  
         for you.  20080126:

         understand the format.  
   20071209:
         Solution: update and reinstall usr.sbin/mtree          The acpiec(4) driver has been split into two attachments. If you
           get ACPI errors before the attachment, please update your kernel
 20011004:          configuration file appropriately or see GENERIC for more details.
         Crunchgen has been updated to work via reach-over makefiles. Updating  
         is suggested before running a snapshot build  20071115:
           The it(4) driver has been renamed to itesio(4) and the old port
 20010915:          argument specified in the kernel configuration file is not valid
         The new "ubcperf" code committed by Chuck Silvers removed          anymore. The itesio(4) driver now uses the Super I/O address port

         Solution: "make cleandir && make dependall" in affected  20071028:
         directories.          The pccons(4) driver has been removed from the NetBSD/shark port.
           You need to update any custom kernel configuration file you have

         the instruction described in 20010726 entry.  
   20070913:
 20010803:          A latent bug in dhclient/dhcpd that caused it to be unable to
         (i386 only): i386 kernel now uses new instructions like          enumerate interfaces was fixed.  The bug began to cause
         `fxsave' which old gas doesn't understand.  To build the          problems after 20070911 when the kernel's SIOCGIFCONF
         kernel successfully, you need to build and install new gas          implementation was repaired.  From 20070529 to 20070911 racoon

         rebuilt your userland (and got a new gas).          sufficient to avoid this problem.)  Ensure that both kernel
           and userland are from after 20070913.

         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so  
         before starting your build.  20070319:
