 ^^^^^^^^^^^^^^^  ^^^^^^^^^^^^^^^
 20040410:  20040418:
           Statfs(2) and friends have been replaced with statvfs(2). Before
           installing a newly build userland make sure that you are running
           a newly built kernel with COMPAT_20 set. In addition your libc
           build might not work (undefined SYS_statfs symbol) because make
           clean does not know how to remove files it does not know about
           anymore. Manually remove all objects from the libc build directory.
         In order to build a complete release of 1.5 (post 1.5.3) the following  20040326:
         steps should be performed first:          The method by which athhal-elf.o gets pulled into i386 kernel builds
           has been changed. The file is now stored as a uuencode file in CVS
           and the generated Makefile will use the new .uue rules from bsd.file.mk
           to build it.
                 1. Build and install a new make (usr.bin/make)          This means you must have the latest bsd.files.mk installed when
                 2. Build and install new copies of libcrypto and libssl          building a kernel without USETOOLS=yes.
                    (they are at new major versions so they won't conflict w.  
                     existing libraries).  
           A bug in the cgd(4) blowfish code was corrected, without
           provision of backwards compatibility, after several public
           notices over several months. Users of cgd with blowfish cipher
           ONLY must dump their data before updating their kernels, and
           recreate cgd's and restore data using the new kernel. See
           (recent message to current-users, URL when mail-index has updated)
           On acorn32, the opms and qms drivers have been withdrawn, and
           the old wsqms driver is now called qms.  Kernel config files
           will need updating.  See the ones in sys/arch/acorn32/conf
           for examples.
           On acorn32, the beep and sysbeep devices are no longer
           needed, and will need to be deleted from kernel configuration
           Compatibility for old ffs superblock layouts has been
           added, and the restrictive fsck checks have been reenabled
           when using those layouts.  If you have been using -current
           since 20030402, you may find that fsck again signals fatal
           superblock mismatches.  To repair, make sure you have
           an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
           to complete the filesystem upgrade.  A message has
           been added to the kernel which should detect this problem.
           See the following discussion for more information:
           New binutils builds may fail due to old dependencies.
           It's necessary to "make cleandir" to ensure that
           the dependencies will be rebuilt correctly.
           A newer mkdep is needed.  Error noting that is
                   cc: Ambiguous abbreviation --
           /usr/include/sys/disklabel_mbr.h was removed.
           It's necessary to "make cleandir" to ensure that
           the dependencies will be rebuilt correctly.
           A sign exension bug was fixed which set all the high bits
           of our newly expanded ffs fs_flags.  This should only
           affect users who installed or upgraded in September of 2003.
           A small utility program was posted to tech-kern which
           should fix this problem, and a warning message was added
           to the kernel which should discover and warn about it.  See
           With the addition of siginfo support the old signal trampoline
           code has been deprecated to COMPAT_16. Make sure that your running
           kernel has COMPAT_16 enabled before building userland.
           With the new openssl, there is some header and library shuffling.
           rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
           /usr/lib/libdes* before building.
           Texinfo was updated to 4.6.  To avoid failures when trying to
           build the included texinfo files, do:
           cd src/gnu/usr.bin/texinfo
           make MKINFO=no dependall install
           Groff was updated to 1.19; it's probably necessary to do
                   cd share/mk && make install
                   cd src/gnu/usr.bin/groff
                   make MKMAN=no dependall install
           Due to bugs in the export handling code, invalid export lines
           were accepted before and caused the kernel to panic when
           mountd got restarted because it freed memory that had already
           been freed. This has been fixed and the kernel checks
           export addresses very strictly. If you upgrade your kernel,
           make sure you also upgrade mountd, because if your export
           file contains lines with an old inet4 address syntax (i.e.
           a.b.c or a.b or a), they will get rejected by the new kernel.
           The superblock layout for FFS was changed.  If you have 1.6
           fsck binaries, they will signal a fatal superblock mismatch
           with the first alternate, because they compare too many
           fields (even ones that aren't useful).  If possible, upgrade
           your fsck_ffs binary before using a new kernel.
           None of this signals actual filesystem damage.
           sendmail version 8.12.8 was imported.  Since sendmail is
           now setgid to the smmsp group, and runs in "collection"
           mode for most common activities, there is a new config
           file called submit.cf that needs to live in /etc/mail.
           The generic submit.cf sample in /usr/share/sendmail/cf
           is named netbsd-msp.cf.  Upgrading your regular sendmail
           configuration file is also strongly advised.
           See the section named "MESSAGE SUBMISSION PROGRAM" in
           the updated /usr/share/sendmail/README file for more
           Texinfo was updated to 4.3.  To avoid failures when trying to
           build the included texinfo files, do:
           cd src/gnu/usr.bin/texinfo
           make MKINFO=no dependall install
           The METALOG format changed slightly, to remove the leading
           "${DESTDIR}" from path names.
           This only affects people building with UNPRIVED.
           For complete safety, remove the DESTDIR entirely and
           update tools/mtree, before running make build.
           CVS repository layout was changed.  See the following for details
           if you are using (anonymous) cvs to update your tree.
           install(1) had a '-N dbdir' option added, to specify an
           alternate location to look up users & groups (instead
           of the host system passwd(5) and group(5) databases).
           The build system was modified to take advantage of
           this option (using ${NETBSDSRCDIR}/etc), so if you
           use USETOOLS==no, you may have to rebuild and
           reinstall usr.bin/xinstall first.
           fparseln(3) moved from libutil to libc.
           If building to DESTDIR=/, reinstall the includes
           and rebuild libc:
                   make includes
                   make do-lib-libc
           If using build.sh, "cd tools/compat && make clean"
           before rebuilding the tools.
           The mk.conf(5) variable SYS_INCLUDE has been deprecated,
           including the optional "SYS_INCLUDE=symlinks" support.
           All header files, including <sys/*.h> are copied into
           The C run-time support files crtbegin.o and crtend.o
           (and their companions crtbeginS.o and crtendS.o) were
           split up, with new crti.o and crtn.o files resulting.
           This means that libtool needs to be rebuilt once the
           new libraries are installed.  The process of rebuilding
           libtool will cause it to automatically notice the new
           required files, but it *must* be rebuilt in order to
           do this.
           An out-of-date libtool will result in shared libraries
           which lack _init() and _fini() routines, which means that
           their global contructors/destructors will not be invoked.
           A bug related to how ARM ELF objects were tagged has been
           NetBSD ARM ELF uses the soft-VFP floating point model by
           default.  However, the assembler lacked support for marking
           objects as using the VFP floating point format, and the
           compiler was not properly passing the flag indicating "soft-VFP"
           to the assembler.
           Unfortunately, this means that the linker will now consider
           old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
           incompatible with new (properly marked) objects.
           The problem will only manifest itself if you attempt to compile
           a new program using the fixed toolchain, and link that program
           against old libraries which do not have the proper "softvfp"
           The only work-around for the problem is to recompile all of
           the libraries on the system.  The easiest way to do this for
           system libraries is to install a binary snapshot; they are
           generally available on releng.NetBSD.org.  Any packages you
           have installed which supply libraries will have to be recompiled
           if you wish to link new programs against those libraries.
           If you have questions about this matter, please contact
           Systrace has been improved to support privilege elevation.
           Updating the kernel requires the userland part of systrace
           to be rebuilt.
           The config(8) grammar was changed to allow options to register
           dependencies on attributes, as well as other options.  Users
           must update and reinstall usr.sbin/config before building a new
           A new attribute dependency syntax was introduced to config(8),
           which is now used by the SCSI configuration description.  Users
           must update and reinstall usr.sbin/config before building a new
           Several changes have been made to the autoconfiguration
           framework.  Users must update and reinstall usr.sbin/config
           before building a new kernel.
           The i386mp branch has been merged.  To compile a kernel, users
           will need to add the option 'cpu* at mainbus?' to their configuration
           file.  Multiprocessor kernels will need
           ioapic*         at mainbus? apid ?
           options         MULTIPROCESSOR
           options         COM_MPLOCK
           MKDYNAMICROOT=yes enabled by default, which means that
           certain shared libraries are installed into /lib, the shared
           linker is installed into /libexec, and all programs in /bin
           and /sbin are dynamically linked.
           If you do not use "make build", you should ensure that
           you have the libraries and shared linker in the new locations,
                   make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
           USE_NEW_TOOLCHAIN has been replaced with:
               -   TOOLCHAIN_MISSING -- set to "yes" on platforms for which
                   there is no working in-tree toolchain (hppa, ns32k, sh5,
               -   EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
                   root of an external toolchain (e.g. /usr/local/gnu).  This
                   enables the cross-build framework even for TOOLCHAIN_MISSING
           gehenna-devsw has been merged into the trunk. Need to update and
           reinstall usr.sbin/config before building the kernel.
           Crunched rescue tools (contents of /bin and /sbin, plus others)
           are now provided in /rescue.
           To ensure that these are built statically linked (no matter
           what the setting of LDSTATIC is), use a crunchgen(1) built
           from sources newer than 20020820 (see the next entry).
           crunchgen(1) changed to ensure that the generated program
           is statically linked.
           Solution: update and reinstall usr.bin/crunch
           smmsp user/group has been added for sendmail.
           Add the following into /etc/group:
           and the following to /etc/master.passwd (via vipw):
           smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin
           sshd user/group has been added.  Need to hand add this in, or sshd
           will not let you log in (with default, or UsePrivlegeSeparation=yes)
           Add the following into /etc/group:
           and the following to /etc/master.passwd (via vipw):
           sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
           Also /var/chroot/sshd directory needs to be present (digged as part of
           the build process).
           NBUILDJOBS obsoleted in favor of just using -j.
           etc/postinstall added, which performs various checks for
           configuration file updates and changes, and can fix most of
           the problems identified.
           This should make it much easier to upgrade a system's
           configuration from earlier systems (as far back as NetBSD 1.5).
           <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.
           Build and install at usr.bin/xinstall before the build.
           Raw IPv6 socket now makes strict checking for sa_family and sa_len
           on send(2) operation.  Be sure to have sbin/rtsol and usr.sbin/rtsold
           newer than November 2001 when you upgrade the kernel.
           ssh configuration files were moved from /etc to /etc/ssh.  Beware
           if you restart your machine from remote.  Note that sshd.conf needs
           to be changed (due to the use of "/etc" inside).
           Users of the VAX port will need to rebuild and install gas
           so it deal with the now present register prefix used in all
           the VAX assembly files.
           ntpd user/group has been added.  Need to hand add this in or builds
           will break as mtree aborts early.
           Add the following into /etc/group:
           and the following to /etc/master.passwd (via vipw):
           ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
           If you're attempting to build a snapshot on sparc64 and are getting
           reloc errors from the toolchain groff binary this means your native
           toolchain has some broken C++ bits.
           To fix:
           Build a new toolchain (i.e. build.sh -t)
           Use the new toolchain to build and install natively (i.e. /usr/lib)
           After this a snapshot will be able to be built.
           In order for a sparc64 build to work you must have a working awk. If
           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
           point is broken.
           To build:
           remake and install gnu/lib/libgcc
           remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
           against the new libgcc.a)
           Kernel config information was changed to use defflag in
           the various "files" files.  Bug fixes to config(8) are
           required in order for this to work properly.  Make sure
           to build and install in usr.sbin/config before attempting
           to build a new kernel.
           libc/locale/wcstod.c now needs new lint(1). Update lint(1)
           before building libc.
           The new document BUILDING.mdoc (view with nroff | more, or
           see pre-generated .txt and .html versions) describes the build
           procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN
           build process, are intended in the long run to replace this
           manual update log.
           Users building a USE_NEW_TOOLCHAIN system should read the
           BUILDING document for caveats.  Generally, BUILDING supersedes
           UPDATING for these systems, as tool updating is taken care of
           by the new build system.
           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.
           /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
           Crunchgen has been updated to work via reach-over makefiles. Updating
           is suggested before running a snapshot build
           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
           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.
           (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]
           Bootloader update on ELF platforms.  DDB in kernels from before
           this will be unable to read symbol tables provided by newer
           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
           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.
           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.
           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:
           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.
           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.
           prepare the code to compile with stricter gcc flags. in
           particular start eliminating redundant declarations. Yacc
           needs to be installed before make build.
           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.
           bsd.subdir.mk committed 20001230 had a bug which caused
           afterinstall targets to run too soon; update again.
           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.
           The `ca' device driver has been replaced by `ld'; although the
           major and minor numbers haven't changed, you should update your /dev
           The following make directives are obsoleted.
           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}.
   Hints for a more successful build:
       Build a new kernel first:
           This makes sure that any new system calls or features
              expected by the new userland will be present.  This
              helps to avoid critical errors when upgrading.
       Use object directories:
           This helps to keep stale object
              files from polluting the build if a Makefile "forgets"
              about one.  It also makes it easier to clean up after
              a build.  It's also necessary if you want to use the
              same source tree for multiple machines.
              To use object directories:
               a) cd /usr/src ; make cleandir
               b) Add "OBJMACHINE=yes" to /etc/mk.conf
               c) Add "MKOBJDIRS=yes" to /etc/mk.conf
               d) cd /usr/src ; make build
              Note that running "make obj" in a directory will create
              in obj.$MACHINE directory.
       Build to a DESTDIR:
           This helps to keep old
              installed files (especially libraries) from interfering
              with the new build.
              To build to a DESTDIR, set the DESTDIR environment
              variable before running make build.  It should be set to
              the pathname of an initially empty directory.
              Problems: you might need to update critical utilities
                   without using DESTDIR since nothing is executed
                   from what is installed in DESTDIR.
                   (See critical utils, below)
       Build often:
           This keeps critical utilities current enough to not choke
           on any other part of the source tree that depends on up to
           date functionality.
   What to do if things don't work:
   When things don't work there is usually a few things that commonly
   should be done.
       1)  make includes
           This should be done automatically by make build.
       2)  cd share/mk && make install
           Again, automatically done by make build.
   Failsafe rebuild of a small part of the tree:
   To make sure you rebuild something correctly you want to do
   something like the following:
       1)  Make sure the includes and .mk files are up to date.
       2)  Make sure any program used to build the particular
           utility is up to date.  (yacc, lex, etc...)
       3)  cd ...path/to/util...
           make cleandir
           rm ...all obj directories...
           make cleandir                   # yes, again
           make obj
           make depend && make
   Failsafe rebuild of the entire tree:
   If you really want to make sure the source tree is clean and
   ready for a build try the following.  Note that sourcing /etc/mk.conf
   (a make(1) Makefile) in this manner is not right, and will not work
   for anyone who uses any make(1) features in /etc/mk.conf.

   Critical utilities:
   Other problems and possible solutions:
   Symptom:Unreasonable compiler errors.
   Fix:    Rebuild gnu/usr.bin/egcs
   Symptom:Complaints involving a Makefile.
   Fix:    Rebuild usr.bin/make:
           cd usr.bin/make && make && make install
           Or, a failsafe method if that doesn't work:
           cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
   Fix:    Make sure .mk files are up to date.
           cd share/mk && make install
   Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
   Fix:    Rebuild usr.sbin/config
   Fix:    Rebuild usr.bin/yacc
   Fix:    Rebuild usr.bin/lex
   Fix:    rm /usr/lib/libbfd.a
   Symptom:Obsolete intermediate files are used during compilation
   Fix:    Try the following sequence of commands in the directory in question.
           make cleandir; rm `make print-objdir`; make cleandir; make obj
           (If you built the tree without "make obj" in the past, obsolete files
           may remain.  The command tries to clean everything up)
   Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
   Fix:    Rebuild and install usr.bin/menuc
   Symptom:mklocale not found during build in share/locale/ctype
   Fix:    Build and install usr.bin/mklocale
   Symptom:undefined reference to `__assert13' or `__unsetenv13'
   Fix:    Rebuild and install lib/libc
   Symptom:usr.sbin/config fails to build.
   Fix:    Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
   Symptom:undefined reference to `getprogname' or `setprogname'
   Fix:    Rebuild and install lib/libc
   Symptom:lint does not understand the '-X' option
   Fix:    May need to build & install libs with NOLINT=1 before rebuilding lint
