UPDATING revision 1.295.2.4 1 $NetBSD: UPDATING,v 1.295.2.4 2020/04/21 19:37:29 martin 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.

20 ^^^^^^^^^^^^^^^
21
22 20200311:
23 GCC 8 ports will need cleaning in src/tools/gcc and
24 src/external/gpl3/gcc due to GCC 8.4 update.
25
26 20191118:
27 More architectures were switched to gcc8:
28 i386, ia64 powerpc64, sparc, sparc64, arm
29 The same comments as in 20191022 apply.
30
31 20191112:
32 The LLVM update requires a clean rebuild for all architectures using
33 LLVM during the tools build phase (i386, amd64, aarch64).
34
35 20191022:
36 Ports amd64 and aarch64 switched to GCC 8.3 by default.
37 In-place ("expert mode", build.sh -E) builds are not supported
38 when going from a GCC 7 userland to GCC 8. Do a regular
39 build to a different DESTDIR (or preferably: build.sh -U) at least
40 once and install sets, or download comp.{tar.xz,tgz} from the
41 daily builds and install that before doing the next in-place build.
42
43 20191001:
44 GCC 8.3 was imported. Builds of src/tools/gcc may fail if
45 old builds with GCC 7 output now uses GCC 8. Clean this
46 directory, and also clean src/external/gpl3/gcc.
47
48 20190903:
49 Files with names that coincide with existing files' names on
50 case-insensitive file systems were inadvertently committed, for
51 radeon GPU firmware. We cannot mark these as obsolete for
52 postinstall to fix, so if you updated src since 2019-08-26, and
53 ran build.sh distribution or ran build.sh release, you must
54 manually delete the following files in your DESTDIR (which is
55 usually $OBJDIR/destir.$ARCH), or from / if you have installed
56 them:

125 We will re-import these radeon firmware images another way
126 later.
127
128 20190727:
129 The uefi bootloader has gained tftp support and needs a clean
130 build. If you do update builds, manually clean its object
131 directory by something like:
132 cd sys/arch/i386/stand/efiboot && make clean
133
134 20190723:
135 The jemalloc allocator in libc is now build without extended
136 debugging (for performance reasons). In update builds make sure
137 to rebuild it completly, by removing all affected object files,
138 including compat builds, something like:
139 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
140
141 20190207:
142 GCC 7 switched for many ports. Update builds are likely to fail.
143
144 20180924:
145 A newer OpenSSL version has been imported. If you are doing
146 update builds, make sure to remove all old obj dirs, like:
147 cd /usr/obj && find . -type d -name openssl | xargs rm -rf
148
149 20180717:
150 On aarch64 int64_t and related types have changed from long long
151 to long. This requires recompiling all C++ binaries.
152
153 20180713:
154 On amd64 and i386 static binaries are now build position
155 independend. This requires recompilation of all object
156 files used to create the crunched /rescue binary.
157 Clean the rescue directory in your obj directory before
158 doing an update build, otherwise linking will fail.
159
160 20180414:
161 Existing binutils was migrated to binutils.old. Manual
162 removal of tools/binutils objects directory may be required
163 to fix tools build failure.
164
165 20180311:
166 bdftopcf was updated and may need cleaning in the
167 src/external/mit/xorg/tools/bdftopcf subdirectory if there are
168 link errors.
169
170 20180212:
171 between OpenSSL and GCC updates, many things may fail to build.
172 any failure that looks like GCC or openssl is best handled by
173 a clean destdir and objdir. Full cleandir and destdir deletion
174 is recommended if build failures occur.
175
176 20171225:
177 removal of the vadvise syscall requires manual removal of all
178 associated files from the libc build object directory (including
179 the .depend files) - a command like:
180 cd $OBJ && find . -type d -name libc | xargs rm -rf
181 For architectures that support multiple "compat" binary targets,
182 you'll need to cleanup both the regular libc directory and the
183 compat ones (the above command will do that).
184
185 20171010:
186 a change to the build structure of external/bsd/acpica/bin/iasl
187 means that its objdir (or *.d and .depend at least) might need
188 to be manually removed - or a build done once without -u.
189
190 20170822:
191 a new version of GMP has been imported and probably
192 will break parts of builds related to themselves or GCC, both
193 in the tools and the native section. Remove all GCC, GMP, MPFR
194 and MPC objdirs or build once without -u.
195
196 20170816:
197 a new version of MPFR and MPC have been imported and probably
198 will break parts of builds related to themselves or GCC, both
199 in the tools and the native section. Remove all GCC, GMP, MPFR
200 and MPC objdirs or build once without -u.
201
202 20170402:
203 a new version of dhcpcd has been imported, which does not support
204 update builds from the previous version. Remove your
205 external/bsd/dhcpcd object dir or build once without -u.
206
207 20170211:
208 a new terminfo database has been imported.
209 The structure of it has changed slightly from prior versions and
210 an updated tic tool is required.
211 If you build.sh, don't use -u
212
213 20170207:
214 various arch dependent libc/exect.S files were removed
215 Either remove the obj directories (lib/libc and compat/amd64/i386/lib
216 if it exists) or do a clean build.
217 (This is a bug in the make system, it should be corrected without
218 human intervention, but isn't.)
219
220 20170104:
221 xinput build options have changed.
222 Remove the obj directory (external/mit/xorg/bin/xinput)
223 if you build.sh -u
224
225 20170103:
226 a new version of flex has been imported.
227 Remove the file from obj (external/bsd/flex)
228 if you build.sh -u
229
230 20161014:
231 a new version of OpenSSL has been imported.
232 Remove the files from obj (crypto/external/bsd/openssl)
233 if you build.sh -u
234
235 20161009:
236 a new version of dhcpcd has been imported with slightly changed
237 build infrastructure. When doing a build.sh -u this requires
238 pruning the external/bsd/dhcpcd objdir.
239
240 20160914:
241 i386, amd64, shark, ofppc and macppc have joined shark and x68k
242 ports in using xorg-server 1.18. This requires a clean destdir
243 and a clean objdir.
244
245 20160527:
246 i386 needs a full cleandir or objdir deletion because PIE has
247 been enabled. (see the amd64 entry two down for further info)
248
249 20160418:
250 libedit needs manual removal of all autogenerated files since
251 some of them are not autogenerated anymore. Remember that there
252 might be two copies of libedit if your platform builds "compat".
253
254 20160410:
255 amd64 needs full "make cleandir" or deletion of objdir now that
256 PIE has been enabled for amd64. PIE, or position-independent
257 executables, means all code, including executables and not just
258 shared libraries, is position-independent and hence able to be
259 relocated by ASLR, address space layout randomization.
260
261 The change was made in Makefile variables for compiler and
262 linker flags, for which make(1) does not record dependencies,
263 hence it is unable to detect that all .o files need rebuilding.
264
265 Partial rebuilds with some modified source files will likely
266 fail when linking executables, since the linker refuses to mix
267 position-independent code with position-dependent code in
268 position-independent executables:
269
270 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
271
272 20160401:
273 Ports switching to GCC 5.3 will need a full "make cleandir".
274 Some people have found that cleandir is not sufficient, so if
275 in doubt delete the entire object directory tree for gcc.
276
277 20160306:
278 NetBSD's regexp implementation is now part of libnbcompat.
279 Nblex, nbm4, nbpax, nbsed use it and they may crash on
280 non-NetBSD hosts if linked with stale object files produced
281 while they included a non-NetBSD regex.h.
282 In any case, you should "make cleandir" at least these tools
283 before updating your toolchain.
284
285 20160125:
286 Dtrace has been enabled by default on some architectures.
287 When doing an update build, make sure to clean the etc/mtree
288 object directory before starting the build - otherwise the
289 needed directories in destdir will not be created.
290 An easy way to do this is:
291 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
292
293 20150818:
294 New acpica requires "make cleandir" in src/external/bsd/acpica
295 again.
296
297 20150413:
298 New acpica requires "make cleandir" and reinstalling yacc
299 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
300 also "make cleandir" in /usr/src/external/bsd/acpica.
301
302 20150404:
303 Lint changes require a full rebuild of the tool, so make
304 sure to build without -u option to build.sh, or manually
305 do a make cleandir in src/tools/lint1 and
306 src/usr.bin/xlint.
307
308 20150310:
309 Improvements to openssl for arm mean that update builds of
310 the openssl libraries will fail. A make cleandir in
311 external/bsd/openssl/lib is needed
312
313 20141026:
314 A mishap during the import of pppd may cause your corruption
315 in your cvs directory if you happened to do a cvs update
316 during a short period of time. To fix, just remove the
317 directory src/external/bsd/ppp/dist/pppd completely
318 and let cvs restore it on next update.
319
320 20140721:
321 The src/external/mit/lua/src directory was accidentally created
322 and then deleted in the CVS repository. If you get errors like
323
324 cvs [update aborted]: cannot open directory
325 /cvsroot/src/external/mit/lua/src: No such file or directory
326
327 then delete your local copy of that directory tree and try again.
328
329 20140530:
330 ARM eABI switched to DWARF based exception handling. This requires
331 rebuilding all C++ code. It is strongly advised to do a clean build.
332
333 20140131:
334 The new compiler_rt/libc integration moved a few things. It is strongly
335 advised to do a clean build. At least lib/libc, the compat version(s)
336 of libc, libkern, rump and the kernels need to be cleaned.
337
338 20131227:
339 1. The new ntpd runs in a restricted mode to prevent amplification
340 attacks. If you need ntpdc to work you need to explicitly enable
341 mode7 in your config file. Make sure you put the necessary restrict
342 statements to avoid being exposed.
343 2. strncat has moved from lib/libc to common/lib/libc; you might need
344 to make clean in libc
345
346 20131129:
347 The GMP sources were updated, and builds will likely fail without
348 cleaning their build trees for both tools and in-tree, like below.
349
350 20131128:
351 The MPC and MPFR sources were updated, and builds may require their
352 tools and in-tree directories cleaned for successful updates.
353
354 20130605:
355 The kernel option FAST_IPSEC no longer exists, it's been renamed
356 to IPSEC (and the older IPSEC version removed).
357
358 20130605:
359 Previous freetype installations eroneously installed private
360 header files. If you are building against a non-empty $DESTDIR,
361 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
362
363 20130531:
364 The xdm update may cause build failure due to xdm.man being
365 in the obj tree. Make sure to ensure any like this:
366 nbmake: nbmake: don't know how to make xdm.man. Stop
367 is fixed by deleting the xdm.man in the obj tree.
368
369 20130530:
370 Updates of many xsrc packages will leave old .pc files around.
371 Best to clean out the xsrc objdir entirely before rebuilds.
372
373 20130301:
374 The removal of netiso requires manual removal of /usr/include/netiso
375 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
376
377 20120726:
378 The update of OpenSSL requires cleaning both the OpenSSL build
379 directory and DESTDIR. *Even non-update builds require cleaning
380 DESTDIR.* Builds done without taking these steps may fail, or in
381 some cases may succeed and install broken OpenSSL libraries that
382 cause third-party software to link incorrectly and/or crash.
383
384 20120507:
385 The database schema for makemandb was changed. You will
386 need to update the database using 'makemandb -f' or wait
387 for the next weekly run to fix it.
388
389 20120319:
390 sys/conf/Makefile.kern.inc has been modified to adjust the
391 size of db_symtab automatically. You need to update dbsym in
392 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
393 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
394 mk.conf.
395
396 20120216:
397 Default for MKCATPAGES changed to NO. Update builds will fail
398 unless DESTDIR is cleaned manually. If you built between 20120207
399 and 20120216, daily and weekly could have created an unreadable
400 /var/db/man.db index for apropos. Running makemandb -f or
401 the next run of weekly will fix it.
402
403 20111227:
404 If you built between 20111225 and 20111227 you need to remove
405 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
406 bump has been reverted.
407
408 20111125:
409 The "rnd" pseudodevice has been added to sys/conf/std, which
410 means it should no longer be explicitly listed in kernel
411 configuration files. The line "pseudo-device rnd" should be
412 removed from any custom kernel config files users may have.
413
414 20111119:
415 A problem with the datastructures used by the rndctl(8)
416 utility (pointers in datastructures in an array, making 32->64
417 bit compatibility very painful) has been fixed in a
418 non-backwards-compatible way. If you replace your kernel,
419 replace your rndctl executable too.
420
421 20111001:
422 the prop_*_send_syscall() functions from proplib(3) have been
423 changed and their new version is not backward compatible with the old
424 one. So ensure that all consumers of these functions (currently:
425 quota2 code and its tests) are updated together with the new lib.
426
427 20110817:
428 sparc has been changed to use GCC 4.5.3, so any objdir or
429 DESTDIR for them should be deleted before updating.
430
431 20110806:
432 i386 and amd64 have been changed to use GCC 4.5.3, so any
433 objdir or DESTDIR for them should be deleted before updating.
434
435 20110805:
436 The update to GCC 4.5.3 requires a non-trivial portion of
437 the tree to be cleaned. Best to delete both objdir and
438 DESTDIR before running this update. So far, only the
439 sparc64, mips and powerpc platforms have changed.
440
441 20110803:
442 The layout of external/public-domain/xz has changed. To do an
443 update build you will have to remove the contents of the OBJDIR
444 for external/public-domain/xz/bin by hand as the xz entry there
445 is now a directory.
446
447 20110410:
448 The configuration of src/tools/gcc has changed. To do an
449 update build you have to clean both tools/binutils and
450 tools/gcc by hand.
451
452 20110328:
453 Building the Xorg binary was moved into a subdirectory to fix
454 ordering issues with "make all". It may be necessary to remove
455 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
456 if your update build fails, as the "Xorg" entry there is now a
457 directory.
458
459 20110121:
460 Assembler files no longer use -traditional-cpp. This can break
461 the build of individual parts of the tree. This is handled
462 correctly by build.sh. Manual builds have to update /usr/share/mk
463 and re-run config(1) for any kernel configurations as needed.
464
465 20101217:
466 The tcpdump(8) program was changed to drop privileges and chroot(2)
467 by default. It may be necessary to manually update passwd(5) and
468 group(5) in order to make the program work with existing setups.
469
470 20101125:
471 The latest changes to setenv(3) dissallow setting environment
472 variables with names that contain '='. Revision 1.18 of env.c
473 assumed that this was allowed. Installing a new libc with an
474 old copy of /usr/bin/env causes env x=1 printenv | grep x= to
475 break which affects the autoconf tests for dependency finding,
476 so building gcc will end up printing:
477 checking dependency style of gcc... none
478 configure: error: no usable dependency style found
479 Fix it by rebuilding and re-installing env.
480
481 20101119:
482 Recent Xorg updates in xsrc/external/mit/ may cause various build
483 or run-time problems. Delete your entire DESTDIR and OBJDIR if you
484 have any build problems with xsrc, or problems with mismatched
485 versions between xorg-server and drivers.

487 20100604:
488 The update of ATF to 0.9 causes old tests written in shell to fail
489 unless they are rebuilt. If you are building with MKUPDATE=yes,
490 you need to clean the src/external/bsd/atf/tests/ and the src/tests/
491 trees by hand.
492
493 20100522:
494 Recent Xorg updates in xsrc/external/mit/ will cause various build
495 problems. Delete your entire DESTDIR and OBJDIR if you have any
496 build problems with xsrc.
497
498 20100522:
499 private section of <ctype.h> was splitted, and now mklocale(1)
500 include ctype_local.h, so you have to make cleandir in tools/mklocale.
501
502 20100520:
503 The location of the xkb compiled descriptions has changed. Please
504 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
505
506 20100222:
507 The shared objects file extension has been changed from .so to
508 .pico, in order to avoid conflicts with shared libraries names
509 libXX.so. All now stale regular .so files can be removed from
510 your object directories.
511
512 20100204:
513 The termcap database has been removed from the sources,
514 but has not been marked obsolete so it is not removed
515 from the system when upgrading.
516 As such, you will need to remove them from your object
517 and destination directories.
518
519 20091101:
520 After updating, it may be necessary to make the 'cleandir'
521 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
522 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
523 src/tools/lex/ and src/usr.bin/lex/.
524
525 20091001:
526 On amd64 you must rebuild tools (to get the new binutils)
527 before building a kernel, or the build fails on cpufunc.S.
528
529 20091001:
530 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
531 symlink, failing the build. Delete the link, and the subdir
532 it is in, and retry your build.
533
534 20090718:
535 libc build changed so that strchr() provides the extra entry
536 point for index(). Update build of libc.a (and libc_pic.a)
537 may fail because the archive contains the unwanted index.o.
538 (Similarly for strrchr() and rindex().)
539
540 20090709:
541 Native Xorg was upgraded again. Builds will probably fail again
542 without a clean objdir, at least for src/external/mit/xorg.
543
544 20090616:
545 Native Xorg was upgraded. Builds will need a clean objdir for
546 src/external/mit/xorg. Upgrading a system from sets will not
547 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
548 subdirectory has been changed into a file, and this needs to
549 be manually "rm -r"'ed before installing xbase.tgz.
550
551 20090501:
552 Several new functions were added to string.h/libc, and this
553 can cause autoconf problems during the tool build for people
554 who fail to clean out their tools objects properly. If you
555 note messages about stpcpy, stpncpy or strnlen accompanying a
556 failure during the tool build, clean out all your tools
557 objects and start again.
558
559 20090325:
560 The i386 port was switched to i486 default toolchain. This requires
561 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
562
563 20090126:
564 The __posix_fadvise50 system call changed assembly stub type. You
565 need to 'rm -f __posix_fadvise50.*' in the libc build directory
566 to avoid using the old assembly stub.
567
568 20090202:
569 pkg_install now depends on the pkgdb cache for automatic conflict
570 detection. It is recommented to rebuild the cache with
571 ``pkg_admin rebuild''.
572
573 20090110:
574 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
575 1. Make sure your kernel has COMPAT_50 in it. Build and install.
576 This is needed even in the MODULAR kernel because there is
577 conditionally compiled code in rtsock.c.
578 2. make sure build.sh completes and the binaries in a chroot work
579 before installing.
580 3. If you don't use build.sh and you build directly to root, and
581 your build breaks in the middle, don't despair. Make sure headers
582 are installed properly, and start building libraries first libc
583 and libutil, install them and then continue building all the
584 libraries in src/lib and src/gnu/lib and install them. Once
585 the new libraries are installed, you can restart the build.
586 4. If you compile packages and you notice link time warnings,
587 rebuild the required packages to update their shared libraries.
588 Any package you rebuild will require rebuilding all the packages
589 that depend on it.
590 5. Next time you run pwd_mkdb with the new binary, the file
591 will be upgraded and it will not be backwards compatible.
592 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
593 lastlogx(5)) have been versioned, and there is a heuristic
594 for utmp. You are better off removing the old files after
595 upgrading. The automated clearing of /var/run during
596 boot, and the automated rotating of files in /var/log by
597 newsyslog(8), may mean that you do not have to remove the
598 files manually.
599 7. The optional accounting file (/var/account/acct, see
600 accton(8)) has not been versioned, and will need to be
601 removed. The automatic rotation of the accounting file by
602 /etc/daily limits the bad consequences of failure to remove
603 the file.
604 8. Application software that writes time_t to binary files on
605 disk will break or need attention. Most notably: if you are
606 using PostgreSQL < 8.4, you need to dump your databases,
607 rebuild PostgreSQL with the new time_t, then restore.
608
609 20081219:
610 config(1) has been updated, and one of the files it creates -
611 swapnetbsd.o - has changed format. You need to rebuild config
612 (done automatically by build.sh) and then you need to rerun
613 config on all kernel configuration files before rebuilding those
614 kernels.
615
616 20081205:
617 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
618 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
619 set and will appear as extra files for MKX11=no update builds.
620
621 20081122:
622 On i386, various kernel options(4) in GENERIC including
623 file systems have been disabled and moved into kernel modules.
624 Before trying a new GENERIC kernel, you have to prepare the
625 following files as well as a new GENERIC kernel:
626
627 - build and install kernel modules from src/sys/modules
628
629 - install the latest bootloader, which will load a module
630 for the file system from which the kernel is loaded automatically
631
632 If you have to load your kernel from a file system which is not of
633 the same type as the root file system, you have to load the necessary
634 file system module manually on the boot prompt or in the boot.cfg file.
635
636 20080827:
637 If you built and installed a libc from sources between
638 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
639 which results in false errors reported by lint(1).
640 Since this breaks the libc build itself, manual help is
641 needed -- lint must be disabled temporarily, e.g.:
642 $ (cd lib/libc && make MKLINT=no dependall install)
643
644 20080813:
645 MKDEBUG build was broken because the .depend files did not know
646 about .go files. You need to remove all .depend files and rebuild.
647
648 20080802:
649 A regression in binary compatibility for pthread_mutex_t has
650 been fixed. Unfortunately, the price is breaking compatibility
651 for -current.
652
653 Threaded programs (using libpthread) and C++ programs (using
654 libstdc++) compiled after 20070907 and before 20080802 need to
655 be recompiled.
656
657 One way to find affected pkgsrc packages:
658
659 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
660 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
661
662 20080731:
663 WAPBL (metadata journaling support) has been added, but at this
664 time isn't backwards compatible with pre-WAPBL aware kernels
665 and userland (fsck_ffs in particular). Please make sure you
666 don't use a journaled filesystem with an older kernel/userland,
667 especially an uncleanly mounted journaled filesystem. WAPBL
668 also requires the super block to be in the UFS2 format. You
669 can use fsck_ffs -c 4 to update the superblock format.
670
671 20080721:
672 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
673 isn't defined.
674
675 20080531:
676 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
677 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
678 utility needs to be rebuilt and reinstalled as older binaries
679 won't work correctly. The following sequence of commands:
680
681 $ (cd sys/sys/ && nbmake-$arch includes)
682 $ (cd sbin/drvctl/ && nbmake-$arch clean)
683 $ (cd sbin/drvctl/ && nbmake-$arch all)
684
685 leaves new drvctl utility in sbin/drvctl build directory.
686
687 20080503:
688 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
689
690 20080521:
691 For a while, unprivileged UPDATE builds would fail to
692 succeed at the checkflist stage, complaining that
693 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
694 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
695 If you already hit this problem, update the .mk file,
696 remove ${DESTDIR}/stand/<arch>, and re-run the build.
697
698 20080303:
699 Linker warnings are now fatal if $WARNS>0.
700
701 20080126:
702 The posix_fadvise system call has been changed from an assembly
703 stub, to a c file that calls an assembly stub. You need to
704 'rm -f posix_fadvise.* .depend' in the libc build directory to
705 avoid using the old assembly stub.
706
707 20071209:
708 The acpiec(4) driver has been split into two attachments. If you
709 get ACPI errors before the attachment, please update your kernel
710 configuration file appropriately or see GENERIC for more details.
711
712 20071115:
713 The it(4) driver has been renamed to itesio(4) and the old port
714 argument specified in the kernel configuration file is not valid
715 anymore. The itesio(4) driver now uses the Super I/O address port
716 rather than the EC address port. Please update your kernel
717 configuration file appropriately or see GENERIC for more details.
718
719 20071028:
720 The pccons(4) driver has been removed from the NetBSD/shark port.
721 You need to update any custom kernel configuration file you have
722 to remove any references to pccons (which includes removing the
723 now useless XSERVER option) and replace them with the correct
724 entries for the wscons driver. See the GENERIC configuration file
725 for more details.
726
727 20070913:
728 A latent bug in dhclient/dhcpd that caused it to be unable to
729 enumerate interfaces was fixed. The bug began to cause
730 problems after 20070911 when the kernel's SIOCGIFCONF
731 implementation was repaired. From 20070529 to 20070911 racoon
732 could not enumerate interfaces. (These are noted because
733 normal kernel/userspace version matching hygiene is not
734 sufficient to avoid this problem.) Ensure that both kernel
735 and userland are from after 20070913.
736
737 20070703:
738 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
739 calls the target-specific strip program, and the logic to pass
740 down STRIP from make has been removed. This requires a
741 re-installation of tools.
742
743 20070422:
744 The way OS emulations lookup filenames inside the emulation root
745 has been changed. Rather than modify the pathname (and copy back
746 to userspace) namei() and lookup() directly check the emulation
747 root. One side effect is that absolute symlinks inside the emulated
748 root file system will be relative to that file system - unless they
749 start /../ this is useful when the emulated root is a real install
750 that has such links.
751 This might affect symlinks that have been added to reference outside
752 the emulated root.
753
754 20070412:
755 The pckbc driver on sgimips IP32 has been removed. Use macekbc
756 instead. See the GENERIC32_IP3x kernel configuration for an
757 example.
758
759 20070319:
760 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
761 on many platforms due to incorrect flags settings. If you
762 updated and built after about 20070315, do "nbmake-$arch
763 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
764 rebuild of object files that might have been built
765 incorrectly, and ensure that you have at least
766 src/lib/libc/Makefile 1.130.
767
768 20070210:
769 src/sys/sys/{sa.h,savar.h} were removed.
770 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
771 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
772 will allow dependencies on those files to get get rebuilt
773
774 20070209:
775 The threading model was changed when the newlock2 branch
776 was merged to NetBSD-current. If you boot with a new
777 kernel (version 4.99.10), then you also need a new pthread
778 library (/usr/lib/libpthread.so.0.7). If you boot with
779 an old kernel, then you need the old pthread library
780 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
781 the pthread library in sync, old threaded applications should
782 continue to work with an old or new kernel. Note that named(8)
783 is the only threaded application in the base system.
784
785 20061214:
786 Following the move of string_to_flags() and flags_to_string()
787 from the bin/ls/ sources to libutil, users doing UPDATE builds
788 will need to do a "make cleandir" in
789 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
790 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
791 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
792 as the installation images in distrib/
793 in order to excise stale references to the old stat_flags.h header
794 file in the ls sources -- stat_flags.h has been removed.
795
796 20061108:
797 The configure script used in the src/tools/gcc compiler has been
798 changed to indicate that our libc has ssp support built-in and
799 does not depend on -lssp and -lssp-nonshared. You'll need to
800 make clean in src/tools/gcc first to rebuild the compiler.
801
802 20061009:
803 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
804 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
805
806 20060814:
807 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
808 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
809 kernel configuration for an example. X servers from the last
810 few years should cope.
811
812 20060703:
813 MPACPI is no more. We always configure PCI interrupts using ACPI
814 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
815 to ACPI_SCANPCI. Thanks to work from fvdl.
816
817 20060627:
818 socket(2) has changed, and its system call has been versioned.
819 For userlands with the old version of socket(2), make sure that
820 your kernel has 'options COMPAT_30' set, or else 'bad system call'
821 errors will result.
822
823 Hints for a more successful build:
824 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
825 Use build.sh, but do not use its "expert mode":
826 This will automatically build the tools in the
827 correct order, and it will keep the tools and the
828 new build products from interfering with the running
829 system. This will allow you to ignore most of the
830 other advice in this file.
831 Build a new kernel first:
832 This makes sure that any new system calls or features
833 expected by the new userland will be present. This
834 helps to avoid critical errors when upgrading.
835 Use object directories:
836 This helps to keep stale object
837 files from polluting the build if a Makefile "forgets"
838 about one. It also makes it easier to clean up after
839 a build. It's also necessary if you want to use the
840 same source tree for multiple machines.
841 To use object directories with build.sh:
842 a) invoke build.sh with the "-M" or "-O" options.
843 To use object directories without using build.sh:
844 a) cd /usr/src ; make cleandir
845 b) Add "OBJMACHINE=yes" to /etc/mk.conf
846 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
847 d) cd /usr/src ; make build
848 Note that running "make obj" in a directory will create
849 in obj.$MACHINE directory.
850 Build to a DESTDIR:
851 This helps to keep old installed files (especially libraries)
852 from interfering with the new build.
853 To build to a DESTDIR with build.sh, use the "-D" option.
854 To build to a DESTDIR without using build.sh, set the DESTDIR
855 environment variable before running make build. It should be
856 set to the pathname of an initially empty directory.
857 Problems: if you do not use build.sh, you might need to
858 update critical utilities without using DESTDIR since
859 nothing is executed from what is installed in DESTDIR.
860 (See critical utils, below.)
861 Build often:
862 This keeps critical utilities current enough to not choke
863 on any other part of the source tree that depends on up to
864 date functionality. If you use build.sh, you should not have
865 this problem.
866
867 What to do if things don't work:
868 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
869 When things don't work there are usually a few things that commonly
870 should be done.
871 1) make includes
872 This should be done automatically by make build.
873 2) cd share/mk && make install
874 Again, automatically done by make build.
875
876 Failsafe rebuild of a small part of the tree:
877 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
878 To make sure you rebuild something correctly you want to do
879 something like the following:
880 1) Make sure the includes and .mk files are up to date.
881 2) Make sure any program used to build the particular
882 utility is up to date. (yacc, lex, etc...)
883 3) cd ...path/to/util...
884 make cleandir
885 rm ...all obj directories...
886 make cleandir # yes, again
887 make obj
888 make depend && make
889
890 Failsafe rebuild of the entire tree:
891 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
892 If you really want to make sure the source tree is clean and
893 ready for a build try the following. Note that sourcing /etc/mk.conf
894 (a make(1) Makefile) in this manner is not right, and will not work
895 for anyone who uses any make(1) features in /etc/mk.conf.
896

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