-This file is intended to be a brief introduction to the build
-process and a reference on what to do if something doesn't work.
+This file (UPDATING) is intended to be a brief reference to recent
+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 see Makefile.
+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.

Recent changes:
^^^^^^^^^^^^^^^
+20050531:
+ genassym.sh(8) was moved to genassym(8). You need to either build
+ tools first or install the version of genassym from /usr/sbin before
+ you can build a kernel again.
+
+20050417:
+ postinstall(8) was moved from /etc to /usr/sbin and made part
+ of the "base" set, to make it easier to invoke after an
+ upgrade.
+
+20050325:
+ pcppi(4) was separated in two devices, adding attimer(4). Be sure
+ to add a config line for an attimer(4) device in your kernel
+ configuration, or you won't be able to set the pitch of the beep
+ with wsconsctl. Depending on the default value for the pitch, you
+ might even not hear any more beep. Also, it is advised to attach both
+ devices the same way (i.e., both on isa or both on acpi) or the
+ pcppi(4) device may fail to find the attimer(4) one.
+
+20050211:
+ Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in
+ some of the cross tools to fail if they use configure. Some configure's
+ cache the environment passed in and notice the new environment is
+ different and abort. Doing a clean in tools/ should be enough to
+ make a build continue.
+
+20050109:
+ Since su is using pam by default now, make sure that you have
+ /etc/pam.d populated (postinstall will do that automatically
+ for you). Otherwise su will fail open (i.e. will not require
+ a password).
+
+20041229:
+ Make had a path resolution bug that manifested itself as not
+ being able to install openpam.3. This bug has been fixed, but
+ you might need to rebuild make manually first to get through
+ the build.
+
+20041201:
+ Userland programs have been changed to use /dev/bpf instead of
+ /dev/bpfX. You need to create that device by installing a new
+ MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]*
+
+20041006:
+
+ A bug was introduced into /bin/sh (var.c rev 1.35) which causes
+ variables to not export correctly to subshells in all cases. This
+ will cause builds to break if that version of /bin/sh is installed
+ on the system. The proper version of /bin/sh can be verified with:
+
+ ident /bin/sh | grep var
+
+ Any /bin/sh w. version 1.35 will not work and needs to be updated
+ before attempting a build.
+
+20041001:
+ The ipfilter kernel sources moved from sys/netinet to
+ dist/sys/ipf/netinet. Due to the move some Makefile
+ dependencies are now dangling requiring a make cleandir
+ before they work again (kdump, ktruss, rescue, ipf, and
+ ftp-proxy are the victims).
+
+20040715:
+ The rc.d/sendmail script now uses a heuristic to determine
+ if sendmail should be started at boot time. It checks the
+ contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
+ owner and mode of the sendmail binary to see if any changes
+ to the mail infrastructure have been made. If no changes
+ are detected, it will start an SMTP listener.
+
+ Setting sendmail=NO in /etc/rc.conf will override this.
+
+ If you are only using sendmail by default and only for
+ local delivery, it is important that you also update your
+ sendmail.cf so that the SMTP listener only listens on the
+ loopback interface.
+
+20040715:
+ The method by which athhal-elf.o gets pulled into i386
+ kernel builds has been changed again. The latest version
+ of bsd.files.mk is no longer required.
+
+20040621:
+ Due to the recent rototill of tools/compat it's crucial one starts
+ from a clean objdir under tools/*.
+
+ This is mostly due to generated files (yacc and lex sources) needing
+ to be generated with new rules from bsd.hostprog.mk.
+
+ The safest course is to rm -rf all objects under tools before building.
+
+20040516:
+ The end-user modifiable X11 configuration has been moved
+ from /usr/X11R6/lib/X11/
to /etc/X11/.
+ Ensure that src and xsrc is up to date, and run
+ "make cleandir" in src/x11 before your next build.
+
+ postinstall currently doesn't migrate the files from
+ /usr/X11R6/lib/X11/* to /etc/X11/* although it does
+ detect that this needs to occur, so you'll have to
+ manually move these files yourself.
+
+20040426:
+ Support for the original dynamic sysctl node structure has
+ been removed in favor of the newer layout. This affects
+ consumers of the create and delete interface, as well as
+ the dynamic discovery mechanism. This is believed only to
+ be the sysctl(8) binary itself, at this point in time, so
+ the only effect of this should be that a sysctl binary
+ built from sources dated between 2003/12/04 and 2004/03/24
+ will not work on a kernel built from sources dated after
+ 2004/04/25. If you need a new sysctl binary but build.sh
+ does not work, make sure that your revision of
+ src/sys/sys/sysctl.h is 1.112 (or later), and then the
+ do the following:
+
+ cd /usr/src (or wherever your source tree is)
+ make USETOOLS=no includes
+ cd lib/libc
+ make USETOOLS=no dependall install
+ cd ../../sbin/sysctl
+ make USETOOLS=no dependall install
+
+ If you are using older sysctl binary, GNU autoconf would fail to
+ identify your machine architecture, and tries to build binary for
+ "unknown-unknown-netbsd20F" or something like that. if that happens,
+ make sure to follow the above steps.
+
+20040425:
+ The ffs superblock issues listed below under 20040109 and 20030402
+ are now automatically addressed by the /etc/rc.d/fixsb script or by
+ sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
+ invocation mentioned below will continue to work and is now
+ automated by those scripts. Note that under certain circumstances,
+ affected filesystems upgraded to a -current kernel first before
+ upgrading their userland with the fixsb and fsck_ffs fixes may
+ encounter a 'freeing free inode' panic when writing to the affected
+ filesystem, so it is a good idea to repair the filesystem as soon as
+ possible. For more details on the fixsb script, see pr install/25138.
+
+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 generated .S sources and objects
+ from the libc build directory.
+
+20040326:
+ The method by which athhal-elf.o gets pulled into i386 kernel builds
+ has been changed. The file is now stored as a uuencoded file in CVS
+ and the generated Makefile will use the new .uue rules from bsd.file.mk
+ to build it.
+
+ This means you must have the latest bsd.files.mk installed when
+ building a kernel without USETOOLS=yes.
+
+20040318:
+ 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)
+
+20040313:
+ 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.
+
+20040125:
+ On acorn32, the beep and sysbeep devices are no longer
+ needed, and will need to be deleted from kernel configuration
+ files.
+
+20040109:
+ 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:
+ http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
+
+20031203:
+ New binutils builds may fail due to old dependencies.
+ It's necessary to "make cleandir" to ensure that
+ the dependencies will be rebuilt correctly.
+
+20031111:
+ A newer mkdep is needed. Error noting that is
+ cc: Ambiguous abbreviation --
+
+20031008:
+ /usr/include/sys/disklabel_mbr.h was removed.
+ It's necessary to "make cleandir" to ensure that
+ the dependencies will be rebuilt correctly.
+
+20031007:
+ 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
+ http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
+
+20030906:
+ 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.
+
+20030801:
+ 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.
+
+20030703:
+ 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
+
+20030630:
+ 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
+ (untested).
+
+20030516:
+ 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.
+
+20030402:
+ 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.
+
+20030324:
+ 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
+ information.
+
+20030117:
+ 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
+
+20021223:
+ 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.
+
+20021219:
+ CVS repository layout was changed. See the following for details
+ if you are using (anonymous) cvs to update your tree.
+
+ http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
+
+20021219:
+ 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.
+
+20021130:
+ 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.
+
+20021126:
+ The mk.conf(5) variable SYS_INCLUDE has been deprecated,
+ including the optional "SYS_INCLUDE=symlinks" support.
+ All header files, including are copied into
+ /usr/include.
+
+20021121:
+ 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.
+
+20021121:
+ A bug related to how ARM ELF objects were tagged has been
+ corrected.
+
+ 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"
+ markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
+ WILL CONTINUE TO WORK PROPERLY.
+
+ 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
+ port-arm@NetBSD.org.
+
+20021011:
+ Systrace has been improved to support privilege elevation.
+ Updating the kernel requires the userland part of systrace
+ to be rebuilt.
+
+20021010:
+ 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
+ kernel.
+
+20021009:
+ 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
+ kernel.
+
+20021003:
+ Several changes have been made to the autoconfiguration
+ framework. Users must update and reinstall usr.sbin/config
+ before building a new kernel.
+
+20021001:
+ 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
+
+20020922:
+ 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,
+ with:
+ make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
+
+20020917:
+ 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,
+ x86_64).
+ - 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
+ platforms.
+
+20020906:
+ gehenna-devsw has been merged into the trunk. Need to update and
+ reinstall usr.sbin/config before building the kernel.
+
+20020822:
+ 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).
+
+20020820:
+ crunchgen(1) changed to ensure that the generated program
+ is statically linked.
+
+ Solution: update and reinstall usr.bin/crunch
+
+20020605:
+ smmsp user/group has been added for sendmail.
+
+ Add the following into /etc/group:
+
+ smmsp:*:17:
+
+ and the following to /etc/master.passwd (via vipw):
+
+ smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin
+
+20020515:
+ 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:
+
+ sshd:*:16:
+
+ 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).
+
+20020426:
+ NBUILDJOBS obsoleted in favor of just using -j.
+
+20020426:
+ 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).
+
+20020320:
+ needs a new install(1) for its "-a cmd" support.
+ Build and install at usr.bin/xinstall before the build.
+
+20020319:
+ 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.
+
+20020311:
+ 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).
+
+20020223:
+ 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.
+
+20020118:
+ 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:
+
+ ntpd:*:15:
+
+ and the following to /etc/master.passwd (via vipw):
+
+ ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
+
+20011207:
+ 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)
+
+ gnu/lib/libgcc
+ gnu/lib/libstdc++
+
+ After this a snapshot will be able to be built.
+
+20011201:
+ 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)
+
+20011128:
+ 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.
+
+20011030:
+ libc/locale/wcstod.c now needs new lint(1). Update lint(1)
+ before building libc.
+
+20011029:
+ 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.
+
+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.
