UPDATING revision 1.312 1 $NetBSD: UPDATING,v 1.312 2020/08/20 03:09:34 mrg 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.

19 Recent changes:
20 ^^^^^^^^^^^^^^^
21
22 20200811:
23 GCC updates may require cleaning the objdir. This may occur
24 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming
25 GCC 9 upgrade.
26
27 20200614:
28 blacklist* has been renamed to blocklist*. postinstall(8)
29 should handle the migration
30
31 20200601:
32 Due to a mistake in LIBISPRIVATE handling, .so libraries were
33 created in the build directories and need cleaning.
34
35 20200311:
36 GCC 8 ports will need cleaning in src/tools/gcc and
37 src/external/gpl3/gcc due to GCC 8.4 update.
38
39 20191118:
40 More architectures were switched to gcc8:
41 i386, ia64 powerpc64, sparc, sparc64, arm
42 The same comments as in 20191022 apply.
43
44 20191112:
45 The LLVM update requires a clean rebuild for all architectures using
46 LLVM during the tools build phase (i386, amd64, aarch64).
47
48 20191022:
49 Ports amd64 and aarch64 switched to GCC 8.3 by default.
50 In-place ("expert mode", build.sh -E) builds are not supported
51 when going from a GCC 7 userland to GCC 8. Do a regular
52 build to a different DESTDIR (or preferably: build.sh -U) at least
53 once and install sets, or download comp.{tar.xz,tgz} from the
54 daily builds and install that before doing the next in-place build.
55
56 20191001:
57 GCC 8.3 was imported. Builds of src/tools/gcc may fail if
58 old builds with GCC 7 output now uses GCC 8. Clean this
59 directory, and also clean src/external/gpl3/gcc.
60
61 20190903:
62 Files with names that coincide with existing files' names on
63 case-insensitive file systems were inadvertently committed, for
64 radeon GPU firmware. We cannot mark these as obsolete for
65 postinstall to fix, so if you updated src since 2019-08-26, and
66 ran build.sh distribution or ran build.sh release, you must
67 manually delete the following files in your DESTDIR (which is
68 usually $OBJDIR/destir.$ARCH), or from / if you have installed
69 them:

138 We will re-import these radeon firmware images another way
139 later.
140
141 20190727:
142 The uefi bootloader has gained tftp support and needs a clean
143 build. If you do update builds, manually clean its object
144 directory by something like:
145 cd sys/arch/i386/stand/efiboot && make clean
146
147 20190723:
148 The jemalloc allocator in libc is now build without extended
149 debugging (for performance reasons). In update builds make sure
150 to rebuild it completly, by removing all affected object files,
151 including compat builds, something like:
152 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
153
154 20190207:
155 GCC 7 switched for many ports. Update builds are likely to fail.
156
157 20180924:
158 A newer OpenSSL version has been imported. If you are doing
159 update builds, make sure to remove all old obj dirs, like:
160 cd /usr/obj && find . -type d -name openssl | xargs rm -rf
161
162 20180717:
163 On aarch64 int64_t and related types have changed from long long
164 to long. This requires recompiling all C++ binaries.
165
166 20180713:
167 On amd64 and i386 static binaries are now build position
168 independend. This requires recompilation of all object
169 files used to create the crunched /rescue binary.
170 Clean the rescue directory in your obj directory before
171 doing an update build, otherwise linking will fail.
172
173 20180414:
174 Existing binutils was migrated to binutils.old. Manual
175 removal of tools/binutils objects directory may be required
176 to fix tools build failure.
177
178 20180311:
179 bdftopcf was updated and may need cleaning in the
180 src/external/mit/xorg/tools/bdftopcf subdirectory if there are
181 link errors.
182
183 20180212:
184 between OpenSSL and GCC updates, many things may fail to build.
185 any failure that looks like GCC or openssl is best handled by
186 a clean destdir and objdir. Full cleandir and destdir deletion
187 is recommended if build failures occur.
188
189 20171225:
190 removal of the vadvise syscall requires manual removal of all
191 associated files from the libc build object directory (including
192 the .depend files) - a command like:
193 cd $OBJ && find . -type d -name libc | xargs rm -rf
194 For architectures that support multiple "compat" binary targets,
195 you'll need to cleanup both the regular libc directory and the
196 compat ones (the above command will do that).
197
198 20171010:
199 a change to the build structure of external/bsd/acpica/bin/iasl
200 means that its objdir (or *.d and .depend at least) might need
201 to be manually removed - or a build done once without -u.
202
203 20170822:
204 a new version of GMP has been imported and probably
205 will break parts of builds related to themselves or GCC, both
206 in the tools and the native section. Remove all GCC, GMP, MPFR
207 and MPC objdirs or build once without -u.
208
209 20170816:
210 a new version of MPFR and MPC have been imported and probably
211 will break parts of builds related to themselves or GCC, both
212 in the tools and the native section. Remove all GCC, GMP, MPFR
213 and MPC objdirs or build once without -u.
214
215 20170402:
216 a new version of dhcpcd has been imported, which does not support
217 update builds from the previous version. Remove your
218 external/bsd/dhcpcd object dir or build once without -u.
219
220 20170211:
221 a new terminfo database has been imported.
222 The structure of it has changed slightly from prior versions and
223 an updated tic tool is required.
224 If you build.sh, don't use -u
225
226 20170207:
227 various arch dependent libc/exect.S files were removed
228 Either remove the obj directories (lib/libc and compat/amd64/i386/lib
229 if it exists) or do a clean build.
230 (This is a bug in the make system, it should be corrected without
231 human intervention, but isn't.)
232
233 20170104:
234 xinput build options have changed.
235 Remove the obj directory (external/mit/xorg/bin/xinput)
236 if you build.sh -u
237
238 20170103:
239 a new version of flex has been imported.
240 Remove the file from obj (external/bsd/flex)
241 if you build.sh -u
242
243 20161014:
244 a new version of OpenSSL has been imported.
245 Remove the files from obj (crypto/external/bsd/openssl)
246 if you build.sh -u
247
248 20161009:
249 a new version of dhcpcd has been imported with slightly changed
250 build infrastructure. When doing a build.sh -u this requires
251 pruning the external/bsd/dhcpcd objdir.
252
253 20160914:
254 i386, amd64, shark, ofppc and macppc have joined shark and x68k
255 ports in using xorg-server 1.18. This requires a clean destdir
256 and a clean objdir.
257
258 20160527:
259 i386 needs a full cleandir or objdir deletion because PIE has
260 been enabled. (see the amd64 entry two down for further info)
261
262 20160418:
263 libedit needs manual removal of all autogenerated files since
264 some of them are not autogenerated anymore. Remember that there
265 might be two copies of libedit if your platform builds "compat".
266
267 20160410:
268 amd64 needs full "make cleandir" or deletion of objdir now that
269 PIE has been enabled for amd64. PIE, or position-independent
270 executables, means all code, including executables and not just
271 shared libraries, is position-independent and hence able to be
272 relocated by ASLR, address space layout randomization.
273
274 The change was made in Makefile variables for compiler and
275 linker flags, for which make(1) does not record dependencies,
276 hence it is unable to detect that all .o files need rebuilding.
277
278 Partial rebuilds with some modified source files will likely
279 fail when linking executables, since the linker refuses to mix
280 position-independent code with position-dependent code in
281 position-independent executables:
282
283 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
284
285 20160401:
286 Ports switching to GCC 5.3 will need a full "make cleandir".
287 Some people have found that cleandir is not sufficient, so if
288 in doubt delete the entire object directory tree for gcc.
289
290 20160306:
291 NetBSD's regexp implementation is now part of libnbcompat.
292 Nblex, nbm4, nbpax, nbsed use it and they may crash on
293 non-NetBSD hosts if linked with stale object files produced
294 while they included a non-NetBSD regex.h.
295 In any case, you should "make cleandir" at least these tools
296 before updating your toolchain.
297
298 20160125:
299 Dtrace has been enabled by default on some architectures.
300 When doing an update build, make sure to clean the etc/mtree
301 object directory before starting the build - otherwise the
302 needed directories in destdir will not be created.
303 An easy way to do this is:
304 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
305
306 20150818:
307 New acpica requires "make cleandir" in src/external/bsd/acpica
308 again.
309
310 20150413:
311 New acpica requires "make cleandir" and reinstalling yacc
312 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
313 also "make cleandir" in /usr/src/external/bsd/acpica.
314
315 20150404:
316 Lint changes require a full rebuild of the tool, so make
317 sure to build without -u option to build.sh, or manually
318 do a make cleandir in src/tools/lint1 and
319 src/usr.bin/xlint.
320
321 20150310:
322 Improvements to openssl for arm mean that update builds of
323 the openssl libraries will fail. A make cleandir in
324 external/bsd/openssl/lib is needed
325
326 20141026:
327 A mishap during the import of pppd may cause your corruption
328 in your cvs directory if you happened to do a cvs update
329 during a short period of time. To fix, just remove the
330 directory src/external/bsd/ppp/dist/pppd completely
331 and let cvs restore it on next update.
332
333 20140721:
334 The src/external/mit/lua/src directory was accidentally created
335 and then deleted in the CVS repository. If you get errors like
336
337 cvs [update aborted]: cannot open directory
338 /cvsroot/src/external/mit/lua/src: No such file or directory
339
340 then delete your local copy of that directory tree and try again.
341
342 20140530:
343 ARM eABI switched to DWARF based exception handling. This requires
344 rebuilding all C++ code. It is strongly advised to do a clean build.
345
346 20140131:
347 The new compiler_rt/libc integration moved a few things. It is strongly
348 advised to do a clean build. At least lib/libc, the compat version(s)
349 of libc, libkern, rump and the kernels need to be cleaned.
350
351 20131227:
352 1. The new ntpd runs in a restricted mode to prevent amplification
353 attacks. If you need ntpdc to work you need to explicitly enable
354 mode7 in your config file. Make sure you put the necessary restrict
355 statements to avoid being exposed.
356 2. strncat has moved from lib/libc to common/lib/libc; you might need
357 to make clean in libc
358
359 20131129:
360 The GMP sources were updated, and builds will likely fail without
361 cleaning their build trees for both tools and in-tree, like below.
362
363 20131128:
364 The MPC and MPFR sources were updated, and builds may require their
365 tools and in-tree directories cleaned for successful updates.
366
367 20130605:
368 The kernel option FAST_IPSEC no longer exists, it's been renamed
369 to IPSEC (and the older IPSEC version removed).
370
371 20130605:
372 Previous freetype installations eroneously installed private
373 header files. If you are building against a non-empty $DESTDIR,
374 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
375
376 20130531:
377 The xdm update may cause build failure due to xdm.man being
378 in the obj tree. Make sure to ensure any like this:
379 nbmake: nbmake: don't know how to make xdm.man. Stop
380 is fixed by deleting the xdm.man in the obj tree.
381
382 20130530:
383 Updates of many xsrc packages will leave old .pc files around.
384 Best to clean out the xsrc objdir entirely before rebuilds.
385
386 20130301:
387 The removal of netiso requires manual removal of /usr/include/netiso
388 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
389
390 20120726:
391 The update of OpenSSL requires cleaning both the OpenSSL build
392 directory and DESTDIR. *Even non-update builds require cleaning
393 DESTDIR.* Builds done without taking these steps may fail, or in
394 some cases may succeed and install broken OpenSSL libraries that
395 cause third-party software to link incorrectly and/or crash.
396
397 20120507:
398 The database schema for makemandb was changed. You will
399 need to update the database using 'makemandb -f' or wait
400 for the next weekly run to fix it.
401
402 20120319:
403 sys/conf/Makefile.kern.inc has been modified to adjust the
404 size of db_symtab automatically. You need to update dbsym in
405 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
406 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
407 mk.conf.
408
409 20120216:
410 Default for MKCATPAGES changed to NO. Update builds will fail
411 unless DESTDIR is cleaned manually. If you built between 20120207
412 and 20120216, daily and weekly could have created an unreadable
413 /var/db/man.db index for apropos. Running makemandb -f or
414 the next run of weekly will fix it.
415
416 20111227:
417 If you built between 20111225 and 20111227 you need to remove
418 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
419 bump has been reverted.
420
421 20111125:
422 The "rnd" pseudodevice has been added to sys/conf/std, which
423 means it should no longer be explicitly listed in kernel
424 configuration files. The line "pseudo-device rnd" should be
425 removed from any custom kernel config files users may have.
426
427 20111119:
428 A problem with the datastructures used by the rndctl(8)
429 utility (pointers in datastructures in an array, making 32->64
430 bit compatibility very painful) has been fixed in a
431 non-backwards-compatible way. If you replace your kernel,
432 replace your rndctl executable too.
433
434 20111001:
435 the prop_*_send_syscall() functions from proplib(3) have been
436 changed and their new version is not backward compatible with the old
437 one. So ensure that all consumers of these functions (currently:
438 quota2 code and its tests) are updated together with the new lib.
439
440 20110817:
441 sparc has been changed to use GCC 4.5.3, so any objdir or
442 DESTDIR for them should be deleted before updating.
443
444 20110806:
445 i386 and amd64 have been changed to use GCC 4.5.3, so any
446 objdir or DESTDIR for them should be deleted before updating.
447
448 20110805:
449 The update to GCC 4.5.3 requires a non-trivial portion of
450 the tree to be cleaned. Best to delete both objdir and
451 DESTDIR before running this update. So far, only the
452 sparc64, mips and powerpc platforms have changed.
453
454 20110803:
455 The layout of external/public-domain/xz has changed. To do an
456 update build you will have to remove the contents of the OBJDIR
457 for external/public-domain/xz/bin by hand as the xz entry there
458 is now a directory.
459
460 20110410:
461 The configuration of src/tools/gcc has changed. To do an
462 update build you have to clean both tools/binutils and
463 tools/gcc by hand.
464
465 20110328:
466 Building the Xorg binary was moved into a subdirectory to fix
467 ordering issues with "make all". It may be necessary to remove
468 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
469 if your update build fails, as the "Xorg" entry there is now a
470 directory.
471
472 20110121:
473 Assembler files no longer use -traditional-cpp. This can break
474 the build of individual parts of the tree. This is handled
475 correctly by build.sh. Manual builds have to update /usr/share/mk
476 and re-run config(1) for any kernel configurations as needed.
477
478 20101217:
479 The tcpdump(8) program was changed to drop privileges and chroot(2)
480 by default. It may be necessary to manually update passwd(5) and
481 group(5) in order to make the program work with existing setups.
482
483 20101125:
484 The latest changes to setenv(3) dissallow setting environment
485 variables with names that contain '='. Revision 1.18 of env.c
486 assumed that this was allowed. Installing a new libc with an
487 old copy of /usr/bin/env causes env x=1 printenv | grep x= to
488 break which affects the autoconf tests for dependency finding,
489 so building gcc will end up printing:
490 checking dependency style of gcc... none
491 configure: error: no usable dependency style found
492 Fix it by rebuilding and re-installing env.
493
494 20101119:
495 Recent Xorg updates in xsrc/external/mit/ may cause various build
496 or run-time problems. Delete your entire DESTDIR and OBJDIR if you
497 have any build problems with xsrc, or problems with mismatched
498 versions between xorg-server and drivers.
499
500 20100604:
501 The update of ATF to 0.9 causes old tests written in shell to fail
502 unless they are rebuilt. If you are building with MKUPDATE=yes,
503 you need to clean the src/external/bsd/atf/tests/ and the src/tests/
504 trees by hand.
505
506 20100522:
507 Recent Xorg updates in xsrc/external/mit/ will cause various build
508 problems. Delete your entire DESTDIR and OBJDIR if you have any
509 build problems with xsrc.
510
511 20100522:
512 private section of <ctype.h> was splitted, and now mklocale(1)
513 include ctype_local.h, so you have to make cleandir in tools/mklocale.
514
515 20100520:
516 The location of the xkb compiled descriptions has changed. Please
517 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
518
519 20100222:
520 The shared objects file extension has been changed from .so to
521 .pico, in order to avoid conflicts with shared libraries names
522 libXX.so. All now stale regular .so files can be removed from
523 your object directories.
524
525 20100204:
526 The termcap database has been removed from the sources,
527 but has not been marked obsolete so it is not removed
528 from the system when upgrading.
529 As such, you will need to remove them from your object
530 and destination directories.
531
532 20091101:
533 After updating, it may be necessary to make the 'cleandir'
534 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
535 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
536 src/tools/lex/ and src/usr.bin/lex/.
537
538 20091001:
539 On amd64 you must rebuild tools (to get the new binutils)
540 before building a kernel, or the build fails on cpufunc.S.
541
542 20091001:
543 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
544 symlink, failing the build. Delete the link, and the subdir
545 it is in, and retry your build.
546
547 20090718:
548 libc build changed so that strchr() provides the extra entry
549 point for index(). Update build of libc.a (and libc_pic.a)
550 may fail because the archive contains the unwanted index.o.
551 (Similarly for strrchr() and rindex().)
552
553 20090709:
554 Native Xorg was upgraded again. Builds will probably fail again
555 without a clean objdir, at least for src/external/mit/xorg.
556
557 20090616:
558 Native Xorg was upgraded. Builds will need a clean objdir for
559 src/external/mit/xorg. Upgrading a system from sets will not
560 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
561 subdirectory has been changed into a file, and this needs to
562 be manually "rm -r"'ed before installing xbase.tgz.
563
564 20090501:
565 Several new functions were added to string.h/libc, and this
566 can cause autoconf problems during the tool build for people
567 who fail to clean out their tools objects properly. If you
568 note messages about stpcpy, stpncpy or strnlen accompanying a
569 failure during the tool build, clean out all your tools
570 objects and start again.
571
572 20090325:
573 The i386 port was switched to i486 default toolchain. This requires
574 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
575
576 20090126:
577 The __posix_fadvise50 system call changed assembly stub type. You
578 need to 'rm -f __posix_fadvise50.*' in the libc build directory
579 to avoid using the old assembly stub.
580
581 20090202:
582 pkg_install now depends on the pkgdb cache for automatic conflict
583 detection. It is recommented to rebuild the cache with
584 ``pkg_admin rebuild''.
585
586 20090110:
587 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
588 1. Make sure your kernel has COMPAT_50 in it. Build and install.
589 This is needed even in the MODULAR kernel because there is
590 conditionally compiled code in rtsock.c.
591 2. make sure build.sh completes and the binaries in a chroot work
592 before installing.
593 3. If you don't use build.sh and you build directly to root, and
594 your build breaks in the middle, don't despair. Make sure headers
595 are installed properly, and start building libraries first libc
596 and libutil, install them and then continue building all the
597 libraries in src/lib and src/gnu/lib and install them. Once
598 the new libraries are installed, you can restart the build.
599 4. If you compile packages and you notice link time warnings,
600 rebuild the required packages to update their shared libraries.
601 Any package you rebuild will require rebuilding all the packages
602 that depend on it.
603 5. Next time you run pwd_mkdb with the new binary, the file
604 will be upgraded and it will not be backwards compatible.
605 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
606 lastlogx(5)) have been versioned, and there is a heuristic
607 for utmp. You are better off removing the old files after
608 upgrading. The automated clearing of /var/run during
609 boot, and the automated rotating of files in /var/log by
610 newsyslog(8), may mean that you do not have to remove the
611 files manually.
612 7. The optional accounting file (/var/account/acct, see
613 accton(8)) has not been versioned, and will need to be
614 removed. The automatic rotation of the accounting file by
615 /etc/daily limits the bad consequences of failure to remove
616 the file.
617 8. Application software that writes time_t to binary files on
618 disk will break or need attention. Most notably: if you are
619 using PostgreSQL < 8.4, you need to dump your databases,
620 rebuild PostgreSQL with the new time_t, then restore.
621
622 20081219:
623 config(1) has been updated, and one of the files it creates -
624 swapnetbsd.o - has changed format. You need to rebuild config
625 (done automatically by build.sh) and then you need to rerun
626 config on all kernel configuration files before rebuilding those
627 kernels.
628
629 20081205:
630 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
631 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
632 set and will appear as extra files for MKX11=no update builds.
633
634 20081122:
635 On i386, various kernel options(4) in GENERIC including
636 file systems have been disabled and moved into kernel modules.
637 Before trying a new GENERIC kernel, you have to prepare the
638 following files as well as a new GENERIC kernel:
639
640 - build and install kernel modules from src/sys/modules
641
642 - install the latest bootloader, which will load a module
643 for the file system from which the kernel is loaded automatically
644
645 If you have to load your kernel from a file system which is not of
646 the same type as the root file system, you have to load the necessary
647 file system module manually on the boot prompt or in the boot.cfg file.
648
649 20080827:
650 If you built and installed a libc from sources between
651 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
652 which results in false errors reported by lint(1).
653 Since this breaks the libc build itself, manual help is
654 needed -- lint must be disabled temporarily, e.g.:
655 $ (cd lib/libc && make MKLINT=no dependall install)
656
657 20080813:
658 MKDEBUG build was broken because the .depend files did not know
659 about .go files. You need to remove all .depend files and rebuild.
660
661 20080802:
662 A regression in binary compatibility for pthread_mutex_t has
663 been fixed. Unfortunately, the price is breaking compatibility
664 for -current.
665
666 Threaded programs (using libpthread) and C++ programs (using
667 libstdc++) compiled after 20070907 and before 20080802 need to
668 be recompiled.
669
670 One way to find affected pkgsrc packages:
671
672 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
673 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
674
675 20080731:
676 WAPBL (metadata journaling support) has been added, but at this
677 time isn't backwards compatible with pre-WAPBL aware kernels
678 and userland (fsck_ffs in particular). Please make sure you
679 don't use a journaled filesystem with an older kernel/userland,
680 especially an uncleanly mounted journaled filesystem. WAPBL
681 also requires the super block to be in the UFS2 format. You
682 can use fsck_ffs -c 4 to update the superblock format.
683
684 20080721:
685 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
686 isn't defined.
687
688 20080531:
689 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
690 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
691 utility needs to be rebuilt and reinstalled as older binaries
692 won't work correctly. The following sequence of commands:
693
694 $ (cd sys/sys/ && nbmake-$arch includes)
695 $ (cd sbin/drvctl/ && nbmake-$arch clean)
696 $ (cd sbin/drvctl/ && nbmake-$arch all)
697
698 leaves new drvctl utility in sbin/drvctl build directory.
699
700 20080503:
701 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
702
703 20080521:
704 For a while, unprivileged UPDATE builds would fail to
705 succeed at the checkflist stage, complaining that
706 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
707 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
708 If you already hit this problem, update the .mk file,
709 remove ${DESTDIR}/stand/<arch>, and re-run the build.
710
711 20080303:
712 Linker warnings are now fatal if $WARNS>0.
713
714 20080126:
715 The posix_fadvise system call has been changed from an assembly
716 stub, to a c file that calls an assembly stub. You need to
717 'rm -f posix_fadvise.* .depend' in the libc build directory to
718 avoid using the old assembly stub.
719
720 20071209:
721 The acpiec(4) driver has been split into two attachments. If you
722 get ACPI errors before the attachment, please update your kernel
723 configuration file appropriately or see GENERIC for more details.
724
725 20071115:
726 The it(4) driver has been renamed to itesio(4) and the old port
727 argument specified in the kernel configuration file is not valid
728 anymore. The itesio(4) driver now uses the Super I/O address port
729 rather than the EC address port. Please update your kernel
730 configuration file appropriately or see GENERIC for more details.
731
732 20071028:
733 The pccons(4) driver has been removed from the NetBSD/shark port.
734 You need to update any custom kernel configuration file you have
735 to remove any references to pccons (which includes removing the
736 now useless XSERVER option) and replace them with the correct
737 entries for the wscons driver. See the GENERIC configuration file
738 for more details.
739
740 20070913:
741 A latent bug in dhclient/dhcpd that caused it to be unable to
742 enumerate interfaces was fixed. The bug began to cause
743 problems after 20070911 when the kernel's SIOCGIFCONF
744 implementation was repaired. From 20070529 to 20070911 racoon
745 could not enumerate interfaces. (These are noted because
746 normal kernel/userspace version matching hygiene is not
747 sufficient to avoid this problem.) Ensure that both kernel
748 and userland are from after 20070913.
749
750 20070703:
751 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
752 calls the target-specific strip program, and the logic to pass
753 down STRIP from make has been removed. This requires a
754 re-installation of tools.
755
756 20070422:
757 The way OS emulations lookup filenames inside the emulation root
758 has been changed. Rather than modify the pathname (and copy back
759 to userspace) namei() and lookup() directly check the emulation
760 root. One side effect is that absolute symlinks inside the emulated
761 root file system will be relative to that file system - unless they
762 start /../ this is useful when the emulated root is a real install
763 that has such links.
764 This might affect symlinks that have been added to reference outside
765 the emulated root.
766
767 20070412:
768 The pckbc driver on sgimips IP32 has been removed. Use macekbc
769 instead. See the GENERIC32_IP3x kernel configuration for an
770 example.
771
772 20070319:
773 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
774 on many platforms due to incorrect flags settings. If you
775 updated and built after about 20070315, do "nbmake-$arch
776 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
777 rebuild of object files that might have been built
778 incorrectly, and ensure that you have at least
779 src/lib/libc/Makefile 1.130.
780
781 20070210:
782 src/sys/sys/{sa.h,savar.h} were removed.
783 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
784 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
785 will allow dependencies on those files to get get rebuilt
786
787 20070209:
788 The threading model was changed when the newlock2 branch
789 was merged to NetBSD-current. If you boot with a new
790 kernel (version 4.99.10), then you also need a new pthread
791 library (/usr/lib/libpthread.so.0.7). If you boot with
792 an old kernel, then you need the old pthread library
793 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
794 the pthread library in sync, old threaded applications should
795 continue to work with an old or new kernel. Note that named(8)
796 is the only threaded application in the base system.
797
798 20061214:
799 Following the move of string_to_flags() and flags_to_string()
800 from the bin/ls/ sources to libutil, users doing UPDATE builds
801 will need to do a "make cleandir" in
802 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
803 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
804 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
805 as the installation images in distrib/
806 in order to excise stale references to the old stat_flags.h header
807 file in the ls sources -- stat_flags.h has been removed.
808
809 20061108:
810 The configure script used in the src/tools/gcc compiler has been
811 changed to indicate that our libc has ssp support built-in and
812 does not depend on -lssp and -lssp-nonshared. You'll need to
813 make clean in src/tools/gcc first to rebuild the compiler.
814
815 20061009:
816 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
817 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
818
819 20060814:
820 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
821 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
822 kernel configuration for an example. X servers from the last
823 few years should cope.
824
825 20060703:
826 MPACPI is no more. We always configure PCI interrupts using ACPI
827 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
828 to ACPI_SCANPCI. Thanks to work from fvdl.
829
830 20060627:
831 socket(2) has changed, and its system call has been versioned.
832 For userlands with the old version of socket(2), make sure that
833 your kernel has 'options COMPAT_30' set, or else 'bad system call'
834 errors will result.
835
836 Hints for a more successful build:
837 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
838 Use build.sh, but do not use its "expert mode":
839 This will automatically build the tools in the
840 correct order, and it will keep the tools and the
841 new build products from interfering with the running
842 system. This will allow you to ignore most of the
843 other advice in this file.
844 Build a new kernel first:
845 This makes sure that any new system calls or features
846 expected by the new userland will be present. This
847 helps to avoid critical errors when upgrading.
848 Use object directories:
849 This helps to keep stale object
850 files from polluting the build if a Makefile "forgets"
851 about one. It also makes it easier to clean up after
852 a build. It's also necessary if you want to use the
853 same source tree for multiple machines.
854 To use object directories with build.sh:
855 a) invoke build.sh with the "-M" or "-O" options.
856 To use object directories without using build.sh:
857 a) cd /usr/src ; make cleandir
858 b) Add "OBJMACHINE=yes" to /etc/mk.conf
859 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
860 d) cd /usr/src ; make build
861 Note that running "make obj" in a directory will create
862 in obj.$MACHINE directory.
863 Build to a DESTDIR:
864 This helps to keep old installed files (especially libraries)
865 from interfering with the new build.
866 To build to a DESTDIR with build.sh, use the "-D" option.
867 To build to a DESTDIR without using build.sh, set the DESTDIR
868 environment variable before running make build. It should be
869 set to the pathname of an initially empty directory.
870 Problems: if you do not use build.sh, you might need to
871 update critical utilities without using DESTDIR since
872 nothing is executed from what is installed in DESTDIR.
873 (See critical utils, below.)
874 Build often:
875 This keeps critical utilities current enough to not choke
876 on any other part of the source tree that depends on up to
877 date functionality. If you use build.sh, you should not have
878 this problem.
879
880 What to do if things don't work:
881 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
882 When things don't work there are usually a few things that commonly
883 should be done.
884 1) make includes
885 This should be done automatically by make build.
886 2) cd share/mk && make install
887 Again, automatically done by make build.
888
889 Failsafe rebuild of a small part of the tree:
890 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
891 To make sure you rebuild something correctly you want to do
892 something like the following:
893 1) Make sure the includes and .mk files are up to date.
894 2) Make sure any program used to build the particular
895 utility is up to date. (yacc, lex, etc...)
896 3) cd ...path/to/util...
897 make cleandir
898 rm ...all obj directories...
899 make cleandir # yes, again
900 make obj
901 make depend && make
902
903 Failsafe rebuild of the entire tree:
904 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
905 If you really want to make sure the source tree is clean and
906 ready for a build try the following. Note that sourcing /etc/mk.conf
907 (a make(1) Makefile) in this manner is not right, and will not work
908 for anyone who uses any make(1) features in /etc/mk.conf.
909

948 Or, a failsafe method if that doesn't work:
949 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
950
951 Fix: Make sure .mk files are up to date.
952 cd share/mk && make install
953
954 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
955 Fix: Rebuild usr.bin/config
956
957 Symptom:

967 Fix: Try the following sequence of commands in the directory in question.
968 make cleandir; rm `make print-objdir`; make cleandir; make obj
969 (If you built the tree without "make obj" in the past, obsolete files
970 may remain. The command tries to clean everything up)

991 Symptom:Update build fails in src/tools/gcc complaining that a variable
992 (e.g. CPPFLAGS) has changed since the previous run.
993 Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.

995 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
996 No such file or directory.
997 Cause: If a directory is created by mistake, then it is sometimes
998 deleted from the CVS repository using administrative commands
999 that bypass the normal cvs access controls. If your cvs working tree
1000 contains references to a directory that has been deleted on the
1001 server in this way, then "cvs update" reports this error.
1002 Fix: Recursively delete the affected directory from your working tree
1003 and try the update again.
