UPDATING revision 1.309
      1 $NetBSD: UPDATING,v 1.309 2020/06/15 03:39:00 christos Exp $
      2 
      3 This file (UPDATING) is intended to be a brief reference to recent
      4 changes that might cause problems in the build process, and a guide for
      5 what to do if something doesn't work.
      6 
      7 For a more detailed description of the recommended way to build NetBSD
      8 using build.sh, see the BUILDING file.
      9 
     10 Note that much of the advice in this UPDATING file was written before
     11 build.sh existed.  Nevertheless, the advice here may be useful for
     12 working around specific problems with build.sh.
     13 
     14 Sections are marked with "^^^^^".  After the section on "Recent changes"
     15 are several sections containing more general information.
     16 
     17 See also: BUILDING, build.sh, Makefile.
     18 
     19 Recent changes:
     20 ^^^^^^^^^^^^^^^
     21 
     22 20200614:
     23 	blacklist* has been renamed to blocklist*. You need to manually:
     24 	mv /var/db/bl{a,o}cklist.db
     25 	fix npf rules that mention blacklist
     26 	fix rc.conf variables
     27 
     28 20200601:
     29 	Due to a mistake in LIBISPRIVATE handling, .so libraries were
     30 	created in the build directories and need cleaning.
     31 
     32 20200311:
     33 	GCC 8 ports will need cleaning in src/tools/gcc and
     34 	src/external/gpl3/gcc due to GCC 8.4 update.
     35 
     36 20191118:
     37 	More architectures were switched to gcc8:
     38 	    i386, ia64 powerpc64, sparc, sparc64, arm
     39 	The same comments as in 20191022 apply.
     40 
     41 20191112:
     42 	The LLVM update requires a clean rebuild for all architectures using
     43 	LLVM during the tools build phase (i386, amd64, aarch64).
     44 
     45 20191022:
     46 	Ports amd64 and aarch64 switched to GCC 8.3 by default.
     47 	In-place ("expert mode", build.sh -E) builds are not supported
     48 	when going from a GCC 7 userland to GCC 8. Do a regular
     49 	build to a different DESTDIR (or preferably: build.sh -U) at least
     50 	once and install sets, or download comp.{tar.xz,tgz} from the
     51 	daily builds and install that before doing the next in-place build.
     52 
     53 20191001:
     54 	GCC 8.3 was imported.  Builds of src/tools/gcc may fail if
     55 	old builds with GCC 7 output now uses GCC 8.  Clean this
     56 	directory, and also clean src/external/gpl3/gcc.
     57 
     58 20190903:
     59 	Files with names that coincide with existing files' names on
     60 	case-insensitive file systems were inadvertently committed, for
     61 	radeon GPU firmware.  We cannot mark these as obsolete for
     62 	postinstall to fix, so if you updated src since 2019-08-26, and
     63 	ran build.sh distribution or ran build.sh release, you must
     64 	manually delete the following files in your DESTDIR (which is
     65 	usually $OBJDIR/destir.$ARCH), or from / if you have installed
     66 	them:
     67 
     68 		/libdata/firmware/radeon/bonaire_ce.bin

    134 
    135 	We will re-import these radeon firmware images another way
    136 	later.
    137 
    138 20190727:
    139 	The uefi bootloader has gained tftp support and needs a clean
    140 	build. If you do update builds, manually clean its object
    141 	directory by something like:
    142 	cd sys/arch/i386/stand/efiboot && make clean
    143 
    144 20190723:
    145 	The jemalloc allocator in libc is now build without extended
    146 	debugging (for performance reasons). In update builds make sure
    147 	to rebuild it completly, by removing all affected object files,
    148 	including compat builds, something like:
    149 	cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
    150 
    151 20190207:
    152 	GCC 7 switched for many ports.  Update builds are likely to fail.
    153 
    154 20180924:
    155 	A newer OpenSSL version has been imported. If you are doing
    156 	update builds, make sure to remove all old obj dirs, like:
    157 	cd /usr/obj && find . -type d -name openssl | xargs rm -rf
    158 
    159 20180717:
    160 	On aarch64 int64_t and related types have changed from long long
    161 	to long. This requires recompiling all C++ binaries.
    162 
    163 20180713:
    164 	On amd64 and i386 static binaries are now build position
    165 	independend. This requires recompilation of all object
    166 	files used to create the crunched /rescue binary.
    167 	Clean the rescue directory in your obj directory before
    168 	doing an update build, otherwise linking will fail.
    169 
    170 20180414:
    171 	Existing binutils was migrated to binutils.old.  Manual
    172 	removal of tools/binutils objects directory may be required
    173 	to fix tools build failure.
    174 
    175 20180311:
    176 	bdftopcf was updated and may need cleaning in the
    177 	src/external/mit/xorg/tools/bdftopcf subdirectory if there are
    178 	link errors.
    179 
    180 20180212:
    181 	between OpenSSL and GCC updates, many things may fail to build.
    182 	any failure that looks like GCC or openssl is best handled by
    183 	a clean destdir and objdir.  Full cleandir and destdir deletion
    184 	is recommended if build failures occur.
    185 
    186 20171225:
    187 	removal of the vadvise syscall requires manual removal of all
    188 	associated files from the libc build object directory (including
    189 	the .depend files) - a command like:
    190 		cd $OBJ && find . -type d -name libc | xargs rm -rf
    191 	For architectures that support multiple "compat" binary targets,
    192 	you'll need to cleanup both the regular libc directory and the
    193 	compat ones (the above command will do that).
    194 
    195 20171010:
    196 	a change to the build structure of external/bsd/acpica/bin/iasl
    197 	means that its objdir (or *.d and .depend at least) might need
    198 	to be manually removed - or a build done once without -u.
    199 
    200 20170822:
    201 	a new version of GMP has been imported and probably
    202 	will break parts of builds related to themselves or GCC, both
    203 	in the tools and the native section.  Remove all GCC, GMP, MPFR
    204 	and MPC objdirs or build once without -u.
    205 
    206 20170816:
    207 	a new version of MPFR and MPC have been imported and probably
    208 	will break parts of builds related to themselves or GCC, both
    209 	in the tools and the native section.  Remove all GCC, GMP, MPFR
    210 	and MPC objdirs or build once without -u.
    211 
    212 20170402:
    213 	a new version of dhcpcd has been imported, which does not support
    214 	update builds from the previous version. Remove your
    215 	external/bsd/dhcpcd object dir or build once without -u.
    216 
    217 20170211:
    218 	a new terminfo database has been imported.
    219 	The structure of it has changed slightly from prior versions and
    220 	an updated tic tool is required.
    221 	If you build.sh, don't use -u
    222 
    223 20170207:
    224 	various arch dependent libc/exect.S files were removed
    225 	Either remove the obj directories (lib/libc and compat/amd64/i386/lib
    226 	if it exists) or do a clean build.
    227 	(This is a bug in the make system, it should be corrected without
    228 	human intervention, but isn't.)
    229 
    230 20170104:
    231 	xinput build options have changed.
    232 	Remove the obj directory (external/mit/xorg/bin/xinput)
    233 	if you build.sh -u
    234 
    235 20170103:
    236 	a new version of flex has been imported.
    237 	Remove the file from obj (external/bsd/flex)
    238 	if you build.sh -u
    239 
    240 20161014:
    241 	a new version of OpenSSL has been imported.
    242 	Remove the files from obj (crypto/external/bsd/openssl) 
    243 	if you build.sh -u
    244 
    245 20161009:
    246 	a new version of dhcpcd has been imported with slightly changed
    247 	build infrastructure. When doing a build.sh -u this requires
    248 	pruning the external/bsd/dhcpcd objdir.
    249 
    250 20160914:
    251 	i386, amd64, shark, ofppc and macppc have joined shark and x68k
    252 	ports in using xorg-server 1.18. This requires a clean destdir
    253 	and a clean objdir.
    254 
    255 20160527:
    256 	i386 needs a full cleandir or objdir deletion because PIE has
    257 	been enabled. (see the amd64 entry two down for further info)
    258 
    259 20160418:
    260 	libedit needs manual removal of all autogenerated files since
    261 	some of them are not autogenerated anymore. Remember that there
    262 	might be two copies of libedit if your platform builds "compat".
    263 
    264 20160410:
    265 	amd64 needs full "make cleandir" or deletion of objdir now that
    266 	PIE has been enabled for amd64.  PIE, or position-independent
    267 	executables, means all code, including executables and not just
    268 	shared libraries, is position-independent and hence able to be
    269 	relocated by ASLR, address space layout randomization.
    270 
    271 	The change was made in Makefile variables for compiler and
    272 	linker flags, for which make(1) does not record dependencies,
    273 	hence it is unable to detect that all .o files need rebuilding.
    274 
    275 	Partial rebuilds with some modified source files will likely
    276 	fail when linking executables, since the linker refuses to mix
    277 	position-independent code with position-dependent code in
    278 	position-independent executables:
    279 
    280 		.../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
    281 
    282 20160401:
    283 	Ports switching to GCC 5.3 will need a full "make cleandir".
    284 	Some people have found that cleandir is not sufficient, so if
    285 	in doubt delete the entire object directory tree for gcc.
    286 
    287 20160306:
    288 	NetBSD's regexp implementation is now part of libnbcompat.
    289 	Nblex, nbm4, nbpax, nbsed use it and they may crash on
    290 	non-NetBSD hosts if linked with stale object files produced
    291 	while they included a non-NetBSD regex.h.
    292 	In any case, you should "make cleandir" at least these tools
    293 	before updating your toolchain.
    294 
    295 20160125:
    296 	Dtrace has been enabled by default on some architectures.
    297 	When doing an update build, make sure to clean the etc/mtree
    298 	object directory before starting the build - otherwise the
    299 	needed directories in destdir will not be created.
    300 	An easy way to do this is:
    301 	   cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
    302 
    303 20150818:
    304 	New acpica requires "make cleandir" in src/external/bsd/acpica
    305 	again.
    306 
    307 20150413:
    308 	New acpica requires "make cleandir" and reinstalling yacc
    309 	in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
    310 	also "make cleandir" in /usr/src/external/bsd/acpica.
    311 
    312 20150404:
    313 	Lint changes require a full rebuild of the tool, so make
    314 	sure to build without -u option to build.sh, or manually
    315 	do a make cleandir in src/tools/lint1 and
    316 	src/usr.bin/xlint.
    317 
    318 20150310:
    319 	Improvements to openssl for arm mean that update builds of
    320 	the openssl libraries will fail. A make cleandir in
    321 	external/bsd/openssl/lib is needed
    322 
    323 20141026:
    324 	A mishap during the import of pppd may cause your corruption
    325 	in your cvs directory if you happened to do a cvs update
    326 	during a short period of time. To fix, just remove the
    327 	directory src/external/bsd/ppp/dist/pppd completely
    328 	and let cvs restore it on next update.
    329 
    330 20140721:
    331 	The src/external/mit/lua/src directory was accidentally created
    332 	and then deleted in the CVS repository.  If you get errors like
    333 
    334 	cvs [update aborted]: cannot open directory
    335 	/cvsroot/src/external/mit/lua/src: No such file or directory
    336 
    337 	then delete your local copy of that directory tree and try again.
    338 
    339 20140530:
    340 	ARM eABI switched to DWARF based exception handling. This requires
    341 	rebuilding all C++ code. It is strongly advised to do a clean build.
    342 
    343 20140131:
    344 	The new compiler_rt/libc integration moved a few things. It is strongly
    345 	advised to do a clean build. At least lib/libc, the compat version(s)
    346 	of libc, libkern, rump and the kernels need to be cleaned.
    347 
    348 20131227:
    349 	1. The new ntpd runs in a restricted mode to prevent amplification
    350 	   attacks. If you need ntpdc to work you need to explicitly enable
    351 	   mode7 in your config file. Make sure you put the necessary restrict
    352 	   statements to avoid being exposed.
    353 	2. strncat has moved from lib/libc to common/lib/libc; you might need
    354 	   to make clean in libc
    355 
    356 20131129:
    357 	The GMP sources were updated, and builds will likely fail without
    358 	cleaning their build trees for both tools and in-tree, like below.
    359 
    360 20131128:
    361 	The MPC and MPFR sources were updated, and builds may require their
    362 	tools and in-tree directories cleaned for successful updates.
    363 
    364 20130605:
    365 	The kernel option FAST_IPSEC no longer exists, it's been renamed
    366 	to IPSEC (and the older IPSEC version removed).
    367 
    368 20130605:
    369 	Previous freetype installations eroneously installed private
    370 	header files. If you are building against a non-empty $DESTDIR,
    371 	please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
    372 
    373 20130531:
    374 	The xdm update may cause build failure due to xdm.man being
    375 	in the obj tree.  Make sure to ensure any like this:
    376 		nbmake: nbmake: don't know how to make xdm.man. Stop
    377 	is fixed by deleting the xdm.man in the obj tree.
    378 
    379 20130530:
    380 	Updates of many xsrc packages will leave old .pc files around.
    381 	Best to clean out the xsrc objdir entirely before rebuilds.
    382 
    383 20130301:
    384 	The removal of netiso requires manual removal of /usr/include/netiso
    385 	prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
    386 
    387 20120726:
    388 	The update of OpenSSL requires cleaning both the OpenSSL build
    389 	directory and DESTDIR.  *Even non-update builds require cleaning
    390 	DESTDIR.* Builds done without taking these steps may fail, or in
    391 	some cases may succeed and install broken OpenSSL libraries that
    392 	cause third-party software to link incorrectly and/or crash.
    393 
    394 20120507:
    395 	The database schema for makemandb was changed.  You will
    396 	need to update the database using 'makemandb -f' or wait
    397 	for the next weekly run to fix it.
    398 
    399 20120319:
    400 	sys/conf/Makefile.kern.inc has been modified to adjust the
    401 	size of db_symtab automatically.  You need to update dbsym in
    402 	your $TOOLDIR to build kernels with options SYMTAB_SPACE.  If
    403 	you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
    404 	mk.conf.
    405 
    406 20120216:
    407 	Default for MKCATPAGES changed to NO.  Update builds will fail
    408 	unless DESTDIR is cleaned manually.  If you built between 20120207
    409 	and 20120216, daily and weekly could have created an unreadable
    410 	/var/db/man.db index for apropos.  Running makemandb -f or
    411 	the next run of weekly will fix it.
    412 
    413 20111227:
    414 	If you built between 20111225 and 20111227 you need to remove
    415 	/usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
    416 	bump has been reverted.
    417 
    418 20111125:
    419 	The "rnd" pseudodevice has been added to sys/conf/std, which
    420 	means it should no longer be explicitly listed in kernel
    421 	configuration files.  The line "pseudo-device rnd" should be
    422 	removed from any custom kernel config files users may have.
    423 
    424 20111119:
    425 	A problem with the datastructures used by the rndctl(8)
    426 	utility (pointers in datastructures in an array, making 32->64
    427 	bit compatibility very painful) has been fixed in a
    428 	non-backwards-compatible way.  If you replace your kernel,
    429 	replace your rndctl executable too.
    430 
    431 20111001:
    432 	the prop_*_send_syscall() functions from proplib(3) have been
    433 	changed and their new version is not backward compatible with the old
    434 	one.  So ensure that all consumers of these functions (currently:
    435 	quota2 code and its tests) are updated together with the new lib.
    436 
    437 20110817:
    438 	sparc has been changed to use GCC 4.5.3, so any objdir or
    439 	DESTDIR for them should be deleted before updating.
    440 
    441 20110806:
    442 	i386 and amd64 have been changed to use GCC 4.5.3, so any
    443 	objdir or DESTDIR for them should be deleted before updating.
    444 
    445 20110805:
    446 	The update to GCC 4.5.3 requires a non-trivial portion of
    447 	the tree to be cleaned.  Best to delete both objdir and
    448 	DESTDIR before running this update.  So far, only the
    449 	sparc64, mips and powerpc platforms have changed.
    450 
    451 20110803:
    452 	The layout of external/public-domain/xz has changed.  To do an
    453 	update build you will have to remove the contents of the OBJDIR
    454 	for external/public-domain/xz/bin by hand as the xz entry there
    455 	is now a directory.
    456 
    457 20110410:
    458 	The configuration of src/tools/gcc has changed.  To do an
    459 	update build you have to clean both tools/binutils and
    460 	tools/gcc by hand.
    461 
    462 20110328:
    463 	Building the Xorg binary was moved into a subdirectory to fix
    464 	ordering issues with "make all".  It may be necessary to remove
    465 	the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
    466 	if your update build fails, as the "Xorg" entry there is now a
    467 	directory.
    468 
    469 20110121:
    470 	Assembler files no longer use -traditional-cpp.  This can break
    471 	the build of individual parts of the tree.  This is handled
    472 	correctly by build.sh.  Manual builds have to update /usr/share/mk
    473 	and re-run config(1) for any kernel configurations as needed.
    474 
    475 20101217:
    476 	The tcpdump(8) program was changed to drop privileges and chroot(2)
    477 	by default.  It may be necessary to manually update passwd(5) and
    478 	group(5) in order to make the program work with existing setups.
    479 
    480 20101125:
    481 	The latest changes to setenv(3) dissallow setting environment
    482 	variables with names that contain '='.  Revision 1.18 of env.c
    483 	assumed that this was allowed.  Installing a new libc with an
    484 	old copy of /usr/bin/env causes env x=1 printenv | grep x= to
    485 	break which affects the autoconf tests for dependency finding,
    486 	so building gcc will end up printing:
    487 	    checking dependency style of gcc... none
    488 	    configure: error: no usable dependency style found
    489 	Fix it by rebuilding and re-installing env.
    490 
    491 20101119:
    492 	Recent Xorg updates in xsrc/external/mit/ may cause various build
    493 	or run-time problems.  Delete your entire DESTDIR and OBJDIR if you
    494 	have any build problems with xsrc, or problems with mismatched
    495 	versions between xorg-server and drivers.
    496 
    497 20100604:
    498 	The update of ATF to 0.9 causes old tests written in shell to fail
    499 	unless they are rebuilt.  If you are building with MKUPDATE=yes,
    500 	you need to clean the src/external/bsd/atf/tests/ and the src/tests/
    501 	trees by hand.
    502 
    503 20100522:
    504 	Recent Xorg updates in xsrc/external/mit/ will cause various build
    505 	problems.  Delete your entire DESTDIR and OBJDIR if you have any
    506 	build problems with xsrc.
    507 
    508 20100522:
    509 	private section of <ctype.h> was splitted, and now mklocale(1)
    510 	include ctype_local.h, so you have to make cleandir in tools/mklocale.
    511 
    512 20100520:
    513 	The location of the xkb compiled descriptions has changed.  Please
    514 	remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
    515 
    516 20100222:
    517 	The shared objects file extension has been changed from .so to
    518 	.pico, in order to avoid conflicts with shared libraries names
    519 	libXX.so.  All now stale regular .so files can be removed from
    520 	your object directories.
    521 
    522 20100204:
    523 	The termcap database has been removed from the sources,
    524 	but has not been marked obsolete so it is not removed
    525 	from the system when upgrading.
    526 	As such, you will need to remove them from your object
    527 	and destination directories.
    528 
    529 20091101:
    530         After updating, it may be necessary to make the 'cleandir'
    531         target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
    532         'build.sh -u tools' or 'build.sh -u distribution'.  Ditto
    533         src/tools/lex/ and src/usr.bin/lex/.
    534 
    535 20091001:
    536 	On amd64 you must rebuild tools (to get the new binutils)
    537 	before building a kernel, or the build fails on cpufunc.S.
    538 
    539 20091001:
    540 	An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
    541 	symlink, failing the build.  Delete the link, and the subdir
    542 	it is in, and retry your build.
    543 
    544 20090718:
    545 	libc build changed so that strchr() provides the extra entry
    546 	point for index().  Update build of libc.a (and libc_pic.a)
    547 	may fail because the archive contains the unwanted index.o.
    548 	(Similarly for strrchr() and rindex().)
    549 
    550 20090709:
    551 	Native Xorg was upgraded again.  Builds will probably fail again
    552 	without a clean objdir, at least for src/external/mit/xorg.
    553 
    554 20090616:
    555 	Native Xorg was upgraded.  Builds will need a clean objdir for
    556 	src/external/mit/xorg.  Upgrading a system from sets will not
    557 	work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
    558 	subdirectory has been changed into a file, and this needs to
    559 	be manually "rm -r"'ed before installing xbase.tgz.
    560 
    561 20090501:
    562 	Several new functions were added to string.h/libc, and this
    563 	can cause autoconf problems during the tool build for people
    564 	who fail to clean out their tools objects properly.  If you
    565 	note messages about stpcpy, stpncpy or strnlen accompanying a
    566 	failure during the tool build, clean out all your tools
    567 	objects and start again.
    568 
    569 20090325:
    570 	The i386 port was switched to i486 default toolchain.  This requires
    571 	cleaning your src/tools directory and $TOOLDIR and rebuilding them.
    572 
    573 20090126:
    574 	The __posix_fadvise50 system call changed assembly stub type.  You
    575 	need to 'rm -f __posix_fadvise50.*' in the libc build directory
    576 	to avoid using the old assembly stub.
    577 
    578 20090202:
    579 	pkg_install now depends on the pkgdb cache for automatic conflict
    580 	detection.  It is recommented to rebuild the cache with
    581 	``pkg_admin rebuild''.
    582 
    583 20090110:
    584 	time_t and dev_t have been bumped to 64 bit quantities.  To upgrade:
    585 	1. Make sure your kernel has COMPAT_50 in it.  Build and install.
    586 	   This is needed even in the MODULAR kernel because there is
    587 	   conditionally compiled code in rtsock.c.
    588 	2. make sure build.sh completes and the binaries in a chroot work
    589 	   before installing.
    590 	3. If you don't use build.sh and you build directly to root, and
    591 	   your build breaks in the middle, don't despair.  Make sure headers
    592 	   are installed properly, and start building libraries first libc
    593 	   and libutil, install them and then continue building all the
    594 	   libraries in src/lib and src/gnu/lib and install them.  Once
    595 	   the new libraries are installed, you can restart the build.
    596 	4. If you compile packages and you notice link time warnings,
    597 	   rebuild the required packages to update their shared libraries.
    598 	   Any package you rebuild will require rebuilding all the packages
    599 	   that depend on it.
    600 	5. Next time you run pwd_mkdb with the new binary, the file
    601 	   will be upgraded and it will not be backwards compatible.
    602 	6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
    603 	   lastlogx(5)) have been versioned, and there is a heuristic
    604 	   for utmp.  You are better off removing the old files after
    605 	   upgrading.  The automated clearing of /var/run during
    606 	   boot, and the automated rotating of files in /var/log by
    607 	   newsyslog(8), may mean that you do not have to remove the
    608 	   files manually.
    609 	7. The optional accounting file (/var/account/acct, see
    610 	   accton(8)) has not been versioned, and will need to be
    611 	   removed.  The automatic rotation of the accounting file by
    612 	   /etc/daily limits the bad consequences of failure to remove
    613 	   the file.
    614 	8. Application software that writes time_t to binary files on
    615 	   disk will break or need attention.  Most notably: if you are
    616 	   using PostgreSQL < 8.4, you need to dump your databases,
    617 	   rebuild PostgreSQL with the new time_t, then restore.
    618 
    619 20081219:
    620 	config(1) has been updated, and one of the files it creates -
    621 	swapnetbsd.o - has changed format.  You need to rebuild config
    622 	(done automatically by build.sh) and then you need to rerun
    623 	config on all kernel configuration files before rebuilding those
    624 	kernels.
    625 
    626 20081205:
    627 	If you build with MKX11=no, you should remove /etc/rc.d/xdm and
    628 	/etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
    629 	set and will appear as extra files for MKX11=no update builds.
    630 
    631 20081122:
    632 	On i386, various kernel options(4) in GENERIC including
    633 	file systems have been disabled and moved into kernel modules.
    634 	Before trying a new GENERIC kernel, you have to prepare the
    635 	following files as well as a new GENERIC kernel:
    636 
    637 	- build and install kernel modules from src/sys/modules
    638 
    639 	- install the latest bootloader, which will load a module
    640 	  for the file system from which the kernel is loaded automatically
    641 
    642 	If you have to load your kernel from a file system which is not of
    643 	the same type as the root file system, you have to load the necessary
    644 	file system module manually on the boot prompt or in the boot.cfg file.
    645 
    646 20080827:
    647 	If you built and installed a libc from sources between
    648 	2008/08/20 and 2008/08/26 you got a broken strtouq(3)
    649 	which results in false errors reported by lint(1).
    650 	Since this breaks the libc build itself, manual help is
    651 	needed -- lint must be disabled temporarily, e.g.:
    652 	  $ (cd lib/libc && make MKLINT=no dependall install)
    653 
    654 20080813:
    655 	MKDEBUG build was broken because the .depend files did not know
    656 	about .go files.  You need to remove all .depend files and rebuild.
    657 
    658 20080802:
    659 	A regression in binary compatibility for pthread_mutex_t has
    660 	been fixed.  Unfortunately, the price is breaking compatibility
    661 	for -current.
    662 
    663 	Threaded programs (using libpthread) and C++ programs (using
    664 	libstdc++) compiled after 20070907 and before 20080802 need to
    665 	be recompiled.
    666 
    667 	One way to find affected pkgsrc packages:
    668 
    669 	  $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
    670 	  $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
    671 
    672 20080731:
    673 	WAPBL (metadata journaling support) has been added, but at this
    674 	time isn't backwards compatible with pre-WAPBL aware kernels
    675 	and userland (fsck_ffs in particular).  Please make sure you
    676 	don't use a journaled filesystem with an older kernel/userland,
    677 	especially an uncleanly mounted journaled filesystem.  WAPBL
    678 	also requires the super block to be in the UFS2 format.  You
    679 	can use fsck_ffs -c 4 to update the superblock format.
    680 
    681 20080721:
    682 	Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
    683 	isn't defined.
    684 
    685 20080531:
    686 	The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
    687 	from 125 (conflicted with DRVCTLCOMMAND) to 129.  The drvctl(8)
    688 	utility needs to be rebuilt and reinstalled as older binaries
    689 	won't work correctly.  The following sequence of commands:
    690 
    691 	  $ (cd sys/sys/ && nbmake-$arch includes)
    692 	  $ (cd sbin/drvctl/ && nbmake-$arch clean)
    693 	  $ (cd sbin/drvctl/ && nbmake-$arch all)
    694 
    695 	leaves new drvctl utility in sbin/drvctl build directory.
    696 
    697 20080503:
    698 	The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
    699 
    700 20080521:
    701 	For a while, unprivileged UPDATE builds would fail to
    702 	succeed at the checkflist stage, complaining that
    703 	${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
    704 	problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
    705 	If you already hit this problem, update the .mk file,
    706 	remove ${DESTDIR}/stand/<arch>, and re-run the build.
    707 
    708 20080303:
    709 	Linker warnings are now fatal if $WARNS>0.
    710 
    711 20080126:
    712 	The posix_fadvise system call has been changed from an assembly
    713 	stub, to a c file that calls an assembly stub.  You need to
    714 	'rm -f posix_fadvise.* .depend' in the libc build directory to
    715 	avoid using the old assembly stub.
    716 
    717 20071209:
    718 	The acpiec(4) driver has been split into two attachments.  If you
    719 	get ACPI errors before the attachment, please update your kernel
    720 	configuration file appropriately or see GENERIC for more details.
    721 
    722 20071115:
    723 	The it(4) driver has been renamed to itesio(4) and the old port
    724 	argument specified in the kernel configuration file is not valid
    725 	anymore.  The itesio(4) driver now uses the Super I/O address port
    726 	rather than the EC address port.  Please update your kernel
    727 	configuration file appropriately or see GENERIC for more details.
    728 
    729 20071028:
    730 	The pccons(4) driver has been removed from the NetBSD/shark port.
    731 	You need to update any custom kernel configuration file you have
    732 	to remove any references to pccons (which includes removing the
    733 	now useless XSERVER option) and replace them with the correct
    734 	entries for the wscons driver.  See the GENERIC configuration file
    735 	for more details.
    736 
    737 20070913:
    738 	A latent bug in dhclient/dhcpd that caused it to be unable to
    739 	enumerate interfaces was fixed.  The bug began to cause
    740 	problems after 20070911 when the kernel's SIOCGIFCONF
    741 	implementation was repaired.  From 20070529 to 20070911 racoon
    742 	could not enumerate interfaces.  (These are noted because
    743 	normal kernel/userspace version matching hygiene is not
    744 	sufficient to avoid this problem.)  Ensure that both kernel
    745 	and userland are from after 20070913.
    746 
    747 20070703:
    748 	nbinstall has been renamed ${MACHINE_GNU_ARCH}-install.  It
    749 	calls the target-specific strip program, and the logic to pass
    750 	down STRIP from make has been removed.  This requires a
    751 	re-installation of tools.
    752 
    753 20070422:
    754 	The way OS emulations lookup filenames inside the emulation root
    755 	has been changed.  Rather than modify the pathname (and copy back
    756 	to userspace) namei() and lookup() directly check the emulation
    757 	root.  One side effect is that absolute symlinks inside the emulated
    758 	root file system will be relative to that file system - unless they
    759 	start /../ this is useful when the emulated root is a real install
    760 	that has such links.
    761 	This might affect symlinks that have been added to reference outside
    762 	the emulated root.
    763 
    764 20070412:
    765 	The pckbc driver on sgimips IP32 has been removed.  Use macekbc
    766 	instead.  See the GENERIC32_IP3x kernel configuration for an
    767 	example.
    768 
    769 20070319:
    770         src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
    771         on many platforms due to incorrect flags settings.  If you
    772         updated and built after about 20070315, do "nbmake-$arch
    773 	cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
    774 	rebuild of object files that might have been built
    775 	incorrectly, and ensure that you have at least
    776 	src/lib/libc/Makefile 1.130.
    777 
    778 20070210:
    779         src/sys/sys/{sa.h,savar.h} were removed.
    780           find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
    781               | xargs egrep -l '/sa.h|/savar.h' | xargs rm
    782         will allow dependencies on those files to get get rebuilt
    783 
    784 20070209:
    785         The threading model was changed when the newlock2 branch
    786         was merged to NetBSD-current.  If you boot with a new
    787         kernel (version 4.99.10), then you also need a new pthread
    788         library (/usr/lib/libpthread.so.0.7).  If you boot with
    789         an old kernel, then you need the old pthread library
    790         (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
    791         the pthread library in sync, old threaded applications should
    792         continue to work with an old or new kernel.  Note that named(8)
    793 	is the only threaded application in the base system.
    794 
    795 20061214:
    796 	Following the move of string_to_flags() and flags_to_string()
    797 	from the bin/ls/ sources to libutil, users doing UPDATE builds
    798 	will need to do a "make cleandir" in
    799 		tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
    800 		bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
    801 		usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
    802 		as the installation images in distrib/
    803 	in order to excise stale references to the old stat_flags.h header
    804 	file in the ls sources -- stat_flags.h has been removed.
    805 
    806 20061108:
    807 	The configure script used in the src/tools/gcc compiler has been
    808 	changed to indicate that our libc has ssp support built-in and
    809 	does not depend on -lssp and -lssp-nonshared.  You'll need to
    810 	make clean in src/tools/gcc first to rebuild the compiler.
    811 
    812 20061009:
    813 	The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
    814 	available.  Use net.inet{,6}.tcp{,6}.congctl.selected instead.
    815 
    816 20060814:
    817 	The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
    818 	withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
    819 	kernel configuration for an example.  X servers from the last
    820 	few years should cope.
    821 
    822 20060703:
    823 	MPACPI is no more.  We always configure PCI interrupts using ACPI
    824 	if we have an ACPI kernel.  The option MPACPI_SCANPCI has been renamed
    825 	to ACPI_SCANPCI.  Thanks to work from fvdl.
    826 
    827 20060627:
    828 	socket(2) has changed, and its system call has been versioned.
    829 	For userlands with the old version of socket(2), make sure that
    830 	your kernel has 'options COMPAT_30' set, or else 'bad system call'
    831 	errors will result.
    832 
    833 Hints for a more successful build:
    834 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    835     Use build.sh, but do not use its "expert mode":
    836 	This will automatically build the tools in the
    837 	   correct order, and it will keep the tools and the
    838 	   new build products from interfering with the running
    839 	   system.  This will allow you to ignore most of the
    840 	   other advice in this file.
    841     Build a new kernel first:
    842 	This makes sure that any new system calls or features
    843 	   expected by the new userland will be present.  This
    844 	   helps to avoid critical errors when upgrading.
    845     Use object directories:
    846 	This helps to keep stale object
    847 	   files from polluting the build if a Makefile "forgets"
    848 	   about one.  It also makes it easier to clean up after
    849 	   a build.  It's also necessary if you want to use the
    850 	   same source tree for multiple machines.
    851 	   To use object directories with build.sh:
    852 	    a) invoke build.sh with the "-M" or "-O" options.
    853 	   To use object directories without using build.sh:
    854 	    a) cd /usr/src ; make cleandir
    855 	    b) Add "OBJMACHINE=yes" to /etc/mk.conf
    856 	    c) Add "MKOBJDIRS=yes" to /etc/mk.conf
    857 	    d) cd /usr/src ; make build
    858 	   Note that running "make obj" in a directory will create
    859 	   in obj.$MACHINE directory.
    860     Build to a DESTDIR:
    861 	This helps to keep old installed files (especially libraries)
    862 	   from interfering with the new build.
    863 	   To build to a DESTDIR with build.sh, use the "-D" option.
    864 	   To build to a DESTDIR without using build.sh, set the DESTDIR
    865 	   environment variable before running make build.  It should be
    866 	   set to the pathname of an initially empty directory.
    867 	   Problems: if you do not use build.sh, you might need to
    868 		update critical utilities without using DESTDIR since
    869 		nothing is executed from what is installed in DESTDIR.
    870 		(See critical utils, below.)
    871     Build often:
    872 	This keeps critical utilities current enough to not choke
    873 	on any other part of the source tree that depends on up to
    874 	date functionality.  If you use build.sh, you should not have
    875 	this problem.
    876 
    877 What to do if things don't work:
    878 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    879 When things don't work there are usually a few things that commonly
    880 should be done.
    881     1)	make includes
    882 	This should be done automatically by make build.
    883     2)  cd share/mk && make install
    884 	Again, automatically done by make build.
    885 
    886 Failsafe rebuild of a small part of the tree:
    887 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    888 To make sure you rebuild something correctly you want to do
    889 something like the following:
    890     1)  Make sure the includes and .mk files are up to date.
    891     2)  Make sure any program used to build the particular
    892 	utility is up to date.  (yacc, lex, etc...)
    893     3)  cd ...path/to/util...
    894 	make cleandir
    895 	rm ...all obj directories...
    896 	make cleandir			# yes, again
    897 	make obj
    898 	make depend && make
    899 
    900 Failsafe rebuild of the entire tree:
    901 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    902 If you really want to make sure the source tree is clean and
    903 ready for a build try the following.  Note that sourcing /etc/mk.conf
    904 (a make(1) Makefile) in this manner is not right, and will not work
    905 for anyone who uses any make(1) features in /etc/mk.conf.
    906

    908 #!/bin/sh

    911 if [ -z $NETBSDSRCDIR ] ; then
    912     NETBSDSRCDIR=/usr/src
    913 fi
    914 if [ \! -d $NETBSDSRCDIR ] ; then
    915     echo Unable to find sources
    916     exit 1
    917 fi
    918 find $NETBSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;
    919 
    920 if [ -z $BSDOBJDIR ] ; then
    921     BSDOBJDIR=/usr/obj
    922 fi
    923 if [ -d $BSDOBJDIR ] ; then
    924     rm -rf $BSDOBJDIR
    925 fi
    926 
    927 cd $NETBSDSRCDIR && make cleandir
    928 
    929 ---cut here---

    931 Critical utilities:
    932 ^^^^^^^^^^^^^^^^^^^
    933 	usr.bin/compile_et
    934 	usr.bin/make
    935 	usr.bin/yacc
    936 	usr.bin/lex
    937 	usr.bin/xlint
    938 	usr.bin/config
    939 
    940 Other problems and possible solutions:
    941 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    942 Symptom:Complaints involving a Makefile.
    943 Fix:	Rebuild usr.bin/make:
    944 	cd usr.bin/make && make && make install
    945 	Or, a failsafe method if that doesn't work:
    946 	cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
    947 
    948 Fix:	Make sure .mk files are up to date.
    949 	cd share/mk && make install
    950 
    951 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
    952 Fix:	Rebuild usr.bin/config
    953 
    954 Symptom:
    955 Fix:	Rebuild usr.bin/yacc
    956 
    957 Symptom:
    958 Fix:	Rebuild usr.bin/lex
    959 
    960 Symptom:
    961 Fix:	rm /usr/lib/libbfd.a
    962 
    963 Symptom:Obsolete intermediate files are used during compilation
    964 Fix:	Try the following sequence of commands in the directory in question.
    965 	make cleandir; rm `make print-objdir`; make cleandir; make obj
    966 	(If you built the tree without "make obj" in the past, obsolete files
    967 	may remain.  The command tries to clean everything up)
    968 
    969 Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible
    970 	pointer type
    971 Fix:	Rebuild and install usr.bin/menuc
    972 
    973 Symptom:mklocale not found during build in share/locale/ctype
    974 Fix:	Build and install usr.bin/mklocale
    975 
    976 Symptom:undefined reference to `__assert13' or `__unsetenv13'
    977 Fix:    Rebuild and install lib/libc
    978 
    979 Symptom:usr.bin/config fails to build.
    980 Fix:	Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
    981 
    982 Symptom:undefined reference to `getprogname' or `setprogname'
    983 Fix:    Rebuild and install lib/libc
    984 
    985 Symptom:lint does not understand the '-X' option
    986 Fix:    May need to build & install libs with NOLINT=1 before rebuilding lint
    987 
    988 Symptom:Update build fails in src/tools/gcc complaining that a variable
    989 	(e.g. CPPFLAGS) has changed since the previous run.
    990 Fix:    Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
    991 
    992 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
    993 	No such file or directory.
    994 Cause:	If a directory is created by mistake, then it is sometimes
    995 	deleted from the CVS repository using administrative commands
    996 	that bypass the normal cvs access controls.  If your cvs working tree
    997 	contains references to a directory that has been deleted on the
    998 	server in this way, then "cvs update" reports this error.
    999 Fix:	Recursively delete the affected directory from your working tree
   1000 	and try the update again.
