UPDATING revision 1.317 1 $NetBSD: UPDATING,v 1.317 2021/01/09 20:51:08 rillig 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 20201230:
23 lint1/ops.c is no longer autogenerated. If this makes the build
24 fail, clean $OBJDIR/tools/*lint* and $OBJDIR/usr.bin/*xlint*.
25
26 20201016:
27 MIPS kernel modules have been disabled until they work. This will
28 turn up in extra files in the DESTDIR, which should be cleaned.
29
30 20200925:
31 GNU MPC and MPFR have been updated. At least MPFR needs cleaning
32 in both the tools and external dirs.
33
34 20200912:
35 GCC 9 has arrived for Arm and x86 platforms, and will be coming
36 for several more, as will binutils 2.34. Clean as required.
37
38 20200907:
39 GCC 9 is coming, and binutils has been updated for MIPS. This
40 probably requires cleaning the tools/binutils.
41
42 20200811:
43 GCC updates may require cleaning the objdir. This may occur
44 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming
45 GCC 9 upgrade.
46
47 20200614:
48 blacklist* has been renamed to blocklist*. postinstall(8)
49 should handle the migration
50
51 20200601:
52 Due to a mistake in LIBISPRIVATE handling, .so libraries were
53 created in the build directories and need cleaning.
54
55 20200311:
56 GCC 8 ports will need cleaning in src/tools/gcc and
57 src/external/gpl3/gcc due to GCC 8.4 update.
58
59 20191118:
60 More architectures were switched to gcc8:
61 i386, ia64 powerpc64, sparc, sparc64, arm
62 The same comments as in 20191022 apply.
63
64 20191112:
65 The LLVM update requires a clean rebuild for all architectures using
66 LLVM during the tools build phase (i386, amd64, aarch64).
67
68 20191022:
69 Ports amd64 and aarch64 switched to GCC 8.3 by default.
70 In-place ("expert mode", build.sh -E) builds are not supported
71 when going from a GCC 7 userland to GCC 8. Do a regular
72 build to a different DESTDIR (or preferably: build.sh -U) at least
73 once and install sets, or download comp.{tar.xz,tgz} from the
74 daily builds and install that before doing the next in-place build.
75
76 20191001:
77 GCC 8.3 was imported. Builds of src/tools/gcc may fail if
78 old builds with GCC 7 output now uses GCC 8. Clean this
79 directory, and also clean src/external/gpl3/gcc.
80
81 20190903:
82 Files with names that coincide with existing files' names on
83 case-insensitive file systems were inadvertently committed, for
84 radeon GPU firmware. We cannot mark these as obsolete for
85 postinstall to fix, so if you updated src since 2019-08-26, and
86 ran build.sh distribution or ran build.sh release, you must
87 manually delete the following files in your DESTDIR (which is
88 usually $OBJDIR/destir.$ARCH), or from / if you have installed
89 them:

158 We will re-import these radeon firmware images another way
159 later.
160
161 20190727:
162 The uefi bootloader has gained tftp support and needs a clean
163 build. If you do update builds, manually clean its object
164 directory by something like:
165 cd sys/arch/i386/stand/efiboot && make clean
166
167 20190723:
168 The jemalloc allocator in libc is now build without extended
169 debugging (for performance reasons). In update builds make sure
170 to rebuild it completly, by removing all affected object files,
171 including compat builds, something like:
172 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
173
174 20190207:
175 GCC 7 switched for many ports. Update builds are likely to fail.
176
177 20180924:
178 A newer OpenSSL version has been imported. If you are doing
179 update builds, make sure to remove all old obj dirs, like:
180 cd /usr/obj && find . -type d -name openssl | xargs rm -rf
181
182 20180717:
183 On aarch64 int64_t and related types have changed from long long
184 to long. This requires recompiling all C++ binaries.
185
186 20180713:
187 On amd64 and i386 static binaries are now build position
188 independend. This requires recompilation of all object
189 files used to create the crunched /rescue binary.
190 Clean the rescue directory in your obj directory before
191 doing an update build, otherwise linking will fail.
192
193 20180414:
194 Existing binutils was migrated to binutils.old. Manual
195 removal of tools/binutils objects directory may be required
196 to fix tools build failure.
197
198 20180311:
199 bdftopcf was updated and may need cleaning in the
200 src/external/mit/xorg/tools/bdftopcf subdirectory if there are
201 link errors.
202
203 20180212:
204 between OpenSSL and GCC updates, many things may fail to build.
205 any failure that looks like GCC or openssl is best handled by
206 a clean destdir and objdir. Full cleandir and destdir deletion
207 is recommended if build failures occur.
208
209 20171225:
210 removal of the vadvise syscall requires manual removal of all
211 associated files from the libc build object directory (including
212 the .depend files) - a command like:
213 cd $OBJ && find . -type d -name libc | xargs rm -rf
214 For architectures that support multiple "compat" binary targets,
215 you'll need to cleanup both the regular libc directory and the
216 compat ones (the above command will do that).
217
218 20171010:
219 a change to the build structure of external/bsd/acpica/bin/iasl
220 means that its objdir (or *.d and .depend at least) might need
221 to be manually removed - or a build done once without -u.
222
223 20170822:
224 a new version of GMP has been imported and probably
225 will break parts of builds related to themselves or GCC, both
226 in the tools and the native section. Remove all GCC, GMP, MPFR
227 and MPC objdirs or build once without -u.
228
229 20170816:
230 a new version of MPFR and MPC have been imported and probably
231 will break parts of builds related to themselves or GCC, both
232 in the tools and the native section. Remove all GCC, GMP, MPFR
233 and MPC objdirs or build once without -u.
234
235 20170402:
236 a new version of dhcpcd has been imported, which does not support
237 update builds from the previous version. Remove your
238 external/bsd/dhcpcd object dir or build once without -u.
239
240 20170211:
241 a new terminfo database has been imported.
242 The structure of it has changed slightly from prior versions and
243 an updated tic tool is required.
244 If you build.sh, don't use -u
245
246 20170207:
247 various arch dependent libc/exect.S files were removed
248 Either remove the obj directories (lib/libc and compat/amd64/i386/lib
249 if it exists) or do a clean build.
250 (This is a bug in the make system, it should be corrected without
251 human intervention, but isn't.)
252
253 20170104:
254 xinput build options have changed.
255 Remove the obj directory (external/mit/xorg/bin/xinput)
256 if you build.sh -u
257
258 20170103:
259 a new version of flex has been imported.
260 Remove the file from obj (external/bsd/flex)
261 if you build.sh -u
262
263 20161014:
264 a new version of OpenSSL has been imported.
265 Remove the files from obj (crypto/external/bsd/openssl)
266 if you build.sh -u
267
268 20161009:
269 a new version of dhcpcd has been imported with slightly changed
270 build infrastructure. When doing a build.sh -u this requires
271 pruning the external/bsd/dhcpcd objdir.
272
273 20160914:
274 i386, amd64, shark, ofppc and macppc have joined shark and x68k
275 ports in using xorg-server 1.18. This requires a clean destdir
276 and a clean objdir.
277
278 20160527:
279 i386 needs a full cleandir or objdir deletion because PIE has
280 been enabled. (see the amd64 entry two down for further info)
281
282 20160418:
283 libedit needs manual removal of all autogenerated files since
284 some of them are not autogenerated anymore. Remember that there
285 might be two copies of libedit if your platform builds "compat".
286
287 20160410:
288 amd64 needs full "make cleandir" or deletion of objdir now that
289 PIE has been enabled for amd64. PIE, or position-independent
290 executables, means all code, including executables and not just
291 shared libraries, is position-independent and hence able to be
292 relocated by ASLR, address space layout randomization.
293
294 The change was made in Makefile variables for compiler and
295 linker flags, for which make(1) does not record dependencies,
296 hence it is unable to detect that all .o files need rebuilding.
297
298 Partial rebuilds with some modified source files will likely
299 fail when linking executables, since the linker refuses to mix
300 position-independent code with position-dependent code in
301 position-independent executables:
302
303 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
304
305 20160401:
306 Ports switching to GCC 5.3 will need a full "make cleandir".
307 Some people have found that cleandir is not sufficient, so if
308 in doubt delete the entire object directory tree for gcc.
309
310 20160306:
311 NetBSD's regexp implementation is now part of libnbcompat.
312 Nblex, nbm4, nbpax, nbsed use it and they may crash on
313 non-NetBSD hosts if linked with stale object files produced
314 while they included a non-NetBSD regex.h.
315 In any case, you should "make cleandir" at least these tools
316 before updating your toolchain.
317
318 20160125:
319 Dtrace has been enabled by default on some architectures.
320 When doing an update build, make sure to clean the etc/mtree
321 object directory before starting the build - otherwise the
322 needed directories in destdir will not be created.
323 An easy way to do this is:
324 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
325
326 20150818:
327 New acpica requires "make cleandir" in src/external/bsd/acpica
328 again.
329
330 20150413:
331 New acpica requires "make cleandir" and reinstalling yacc
332 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
333 also "make cleandir" in /usr/src/external/bsd/acpica.
334
335 20150404:
336 Lint changes require a full rebuild of the tool, so make
337 sure to build without -u option to build.sh, or manually
338 do a make cleandir in src/tools/lint1 and
339 src/usr.bin/xlint.
340
341 20150310:
342 Improvements to openssl for arm mean that update builds of
343 the openssl libraries will fail. A make cleandir in
344 external/bsd/openssl/lib is needed
345
346 20141026:
347 A mishap during the import of pppd may cause your corruption
348 in your cvs directory if you happened to do a cvs update
349 during a short period of time. To fix, just remove the
350 directory src/external/bsd/ppp/dist/pppd completely
351 and let cvs restore it on next update.
352
353 20140721:
354 The src/external/mit/lua/src directory was accidentally created
355 and then deleted in the CVS repository. If you get errors like
356
357 cvs [update aborted]: cannot open directory
358 /cvsroot/src/external/mit/lua/src: No such file or directory
359
360 then delete your local copy of that directory tree and try again.
361
362 20140530:
363 ARM eABI switched to DWARF based exception handling. This requires
364 rebuilding all C++ code. It is strongly advised to do a clean build.
365
366 20140131:
367 The new compiler_rt/libc integration moved a few things. It is strongly
368 advised to do a clean build. At least lib/libc, the compat version(s)
369 of libc, libkern, rump and the kernels need to be cleaned.
370
371 20131227:
372 1. The new ntpd runs in a restricted mode to prevent amplification
373 attacks. If you need ntpdc to work you need to explicitly enable
374 mode7 in your config file. Make sure you put the necessary restrict
375 statements to avoid being exposed.
376 2. strncat has moved from lib/libc to common/lib/libc; you might need
377 to make clean in libc
378
379 20131129:
380 The GMP sources were updated, and builds will likely fail without
381 cleaning their build trees for both tools and in-tree, like below.
382
383 20131128:
384 The MPC and MPFR sources were updated, and builds may require their
385 tools and in-tree directories cleaned for successful updates.
386
387 20130605:
388 The kernel option FAST_IPSEC no longer exists, it's been renamed
389 to IPSEC (and the older IPSEC version removed).
390
391 20130605:
392 Previous freetype installations eroneously installed private
393 header files. If you are building against a non-empty $DESTDIR,
394 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
395
396 20130531:
397 The xdm update may cause build failure due to xdm.man being
398 in the obj tree. Make sure to ensure any like this:
399 nbmake: nbmake: don't know how to make xdm.man. Stop
400 is fixed by deleting the xdm.man in the obj tree.
401
402 20130530:
403 Updates of many xsrc packages will leave old .pc files around.
404 Best to clean out the xsrc objdir entirely before rebuilds.
405
406 20130301:
407 The removal of netiso requires manual removal of /usr/include/netiso
408 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
409
410 20120726:
411 The update of OpenSSL requires cleaning both the OpenSSL build
412 directory and DESTDIR. *Even non-update builds require cleaning
413 DESTDIR.* Builds done without taking these steps may fail, or in
414 some cases may succeed and install broken OpenSSL libraries that
415 cause third-party software to link incorrectly and/or crash.
416
417 20120507:
418 The database schema for makemandb was changed. You will
419 need to update the database using 'makemandb -f' or wait
420 for the next weekly run to fix it.
421
422 20120319:
423 sys/conf/Makefile.kern.inc has been modified to adjust the
424 size of db_symtab automatically. You need to update dbsym in
425 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
426 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
427 mk.conf.
428
429 20120216:
430 Default for MKCATPAGES changed to NO. Update builds will fail
431 unless DESTDIR is cleaned manually. If you built between 20120207
432 and 20120216, daily and weekly could have created an unreadable
433 /var/db/man.db index for apropos. Running makemandb -f or
434 the next run of weekly will fix it.
435
436 20111227:
437 If you built between 20111225 and 20111227 you need to remove
438 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
439 bump has been reverted.
440
441 20111125:
442 The "rnd" pseudodevice has been added to sys/conf/std, which
443 means it should no longer be explicitly listed in kernel
444 configuration files. The line "pseudo-device rnd" should be
445 removed from any custom kernel config files users may have.
446
447 20111119:
448 A problem with the datastructures used by the rndctl(8)
449 utility (pointers in datastructures in an array, making 32->64
450 bit compatibility very painful) has been fixed in a
451 non-backwards-compatible way. If you replace your kernel,
452 replace your rndctl executable too.
453
454 20111001:
455 the prop_*_send_syscall() functions from proplib(3) have been
456 changed and their new version is not backward compatible with the old
457 one. So ensure that all consumers of these functions (currently:
458 quota2 code and its tests) are updated together with the new lib.
459
460 20110817:
461 sparc has been changed to use GCC 4.5.3, so any objdir or
462 DESTDIR for them should be deleted before updating.
463
464 20110806:
465 i386 and amd64 have been changed to use GCC 4.5.3, so any
466 objdir or DESTDIR for them should be deleted before updating.
467
468 20110805:
469 The update to GCC 4.5.3 requires a non-trivial portion of
470 the tree to be cleaned. Best to delete both objdir and
471 DESTDIR before running this update. So far, only the
472 sparc64, mips and powerpc platforms have changed.
473
474 20110803:
475 The layout of external/public-domain/xz has changed. To do an
476 update build you will have to remove the contents of the OBJDIR
477 for external/public-domain/xz/bin by hand as the xz entry there
478 is now a directory.
479
480 20110410:
481 The configuration of src/tools/gcc has changed. To do an
482 update build you have to clean both tools/binutils and
483 tools/gcc by hand.
484
485 20110328:
486 Building the Xorg binary was moved into a subdirectory to fix
487 ordering issues with "make all". It may be necessary to remove
488 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
489 if your update build fails, as the "Xorg" entry there is now a
490 directory.
491
492 20110121:
493 Assembler files no longer use -traditional-cpp. This can break
494 the build of individual parts of the tree. This is handled
495 correctly by build.sh. Manual builds have to update /usr/share/mk
496 and re-run config(1) for any kernel configurations as needed.
497
498 20101217:
499 The tcpdump(8) program was changed to drop privileges and chroot(2)
500 by default. It may be necessary to manually update passwd(5) and
501 group(5) in order to make the program work with existing setups.
502
503 20101125:
504 The latest changes to setenv(3) dissallow setting environment
505 variables with names that contain '='. Revision 1.18 of env.c
506 assumed that this was allowed. Installing a new libc with an
507 old copy of /usr/bin/env causes env x=1 printenv | grep x= to
508 break which affects the autoconf tests for dependency finding,
509 so building gcc will end up printing:
510 checking dependency style of gcc... none
511 configure: error: no usable dependency style found
512 Fix it by rebuilding and re-installing env.
513
514 20101119:
515 Recent Xorg updates in xsrc/external/mit/ may cause various build
516 or run-time problems. Delete your entire DESTDIR and OBJDIR if you
517 have any build problems with xsrc, or problems with mismatched
518 versions between xorg-server and drivers.
519
520 20100604:
521 The update of ATF to 0.9 causes old tests written in shell to fail
522 unless they are rebuilt. If you are building with MKUPDATE=yes,
523 you need to clean the src/external/bsd/atf/tests/ and the src/tests/
524 trees by hand.
525
526 20100522:
527 Recent Xorg updates in xsrc/external/mit/ will cause various build
528 problems. Delete your entire DESTDIR and OBJDIR if you have any
529 build problems with xsrc.
530
531 20100522:
532 private section of <ctype.h> was splitted, and now mklocale(1)
533 include ctype_local.h, so you have to make cleandir in tools/mklocale.
534
535 20100520:
536 The location of the xkb compiled descriptions has changed. Please
537 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
538
539 20100222:
540 The shared objects file extension has been changed from .so to
541 .pico, in order to avoid conflicts with shared libraries names
542 libXX.so. All now stale regular .so files can be removed from
543 your object directories.
544
545 20100204:
546 The termcap database has been removed from the sources,
547 but has not been marked obsolete so it is not removed
548 from the system when upgrading.
549 As such, you will need to remove them from your object
550 and destination directories.
551
552 20091101:
553 After updating, it may be necessary to make the 'cleandir'
554 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
555 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
556 src/tools/lex/ and src/usr.bin/lex/.
557
558 20091001:
559 On amd64 you must rebuild tools (to get the new binutils)
560 before building a kernel, or the build fails on cpufunc.S.
561
562 20091001:
563 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
564 symlink, failing the build. Delete the link, and the subdir
565 it is in, and retry your build.
566
567 20090718:
568 libc build changed so that strchr() provides the extra entry
569 point for index(). Update build of libc.a (and libc_pic.a)
570 may fail because the archive contains the unwanted index.o.
571 (Similarly for strrchr() and rindex().)
572
573 20090709:
574 Native Xorg was upgraded again. Builds will probably fail again
575 without a clean objdir, at least for src/external/mit/xorg.
576
577 20090616:
578 Native Xorg was upgraded. Builds will need a clean objdir for
579 src/external/mit/xorg. Upgrading a system from sets will not
580 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
581 subdirectory has been changed into a file, and this needs to
582 be manually "rm -r"'ed before installing xbase.tgz.
583
584 20090501:
585 Several new functions were added to string.h/libc, and this
586 can cause autoconf problems during the tool build for people
587 who fail to clean out their tools objects properly. If you
588 note messages about stpcpy, stpncpy or strnlen accompanying a
589 failure during the tool build, clean out all your tools
590 objects and start again.
591
592 20090325:
593 The i386 port was switched to i486 default toolchain. This requires
594 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
595
596 20090126:
597 The __posix_fadvise50 system call changed assembly stub type. You
598 need to 'rm -f __posix_fadvise50.*' in the libc build directory
599 to avoid using the old assembly stub.
600
601 20090202:
602 pkg_install now depends on the pkgdb cache for automatic conflict
603 detection. It is recommented to rebuild the cache with
604 ``pkg_admin rebuild''.
605
606 20090110:
607 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
608 1. Make sure your kernel has COMPAT_50 in it. Build and install.
609 This is needed even in the MODULAR kernel because there is
610 conditionally compiled code in rtsock.c.
611 2. make sure build.sh completes and the binaries in a chroot work
612 before installing.
613 3. If you don't use build.sh and you build directly to root, and
614 your build breaks in the middle, don't despair. Make sure headers
615 are installed properly, and start building libraries first libc
616 and libutil, install them and then continue building all the
617 libraries in src/lib and src/gnu/lib and install them. Once
618 the new libraries are installed, you can restart the build.
619 4. If you compile packages and you notice link time warnings,
620 rebuild the required packages to update their shared libraries.
621 Any package you rebuild will require rebuilding all the packages
622 that depend on it.
623 5. Next time you run pwd_mkdb with the new binary, the file
624 will be upgraded and it will not be backwards compatible.
625 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
626 lastlogx(5)) have been versioned, and there is a heuristic
627 for utmp. You are better off removing the old files after
628 upgrading. The automated clearing of /var/run during
629 boot, and the automated rotating of files in /var/log by
630 newsyslog(8), may mean that you do not have to remove the
631 files manually.
632 7. The optional accounting file (/var/account/acct, see
633 accton(8)) has not been versioned, and will need to be
634 removed. The automatic rotation of the accounting file by
635 /etc/daily limits the bad consequences of failure to remove
636 the file.
637 8. Application software that writes time_t to binary files on
638 disk will break or need attention. Most notably: if you are
639 using PostgreSQL < 8.4, you need to dump your databases,
640 rebuild PostgreSQL with the new time_t, then restore.
641
642 20081219:
643 config(1) has been updated, and one of the files it creates -
644 swapnetbsd.o - has changed format. You need to rebuild config
645 (done automatically by build.sh) and then you need to rerun
646 config on all kernel configuration files before rebuilding those
647 kernels.
648
649 20081205:
650 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
651 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
652 set and will appear as extra files for MKX11=no update builds.
653
654 20081122:
655 On i386, various kernel options(4) in GENERIC including
656 file systems have been disabled and moved into kernel modules.
657 Before trying a new GENERIC kernel, you have to prepare the
658 following files as well as a new GENERIC kernel:
659
660 - build and install kernel modules from src/sys/modules
661
662 - install the latest bootloader, which will load a module
663 for the file system from which the kernel is loaded automatically
664
665 If you have to load your kernel from a file system which is not of
666 the same type as the root file system, you have to load the necessary
667 file system module manually on the boot prompt or in the boot.cfg file.
668
669 20080827:
670 If you built and installed a libc from sources between
671 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
672 which results in false errors reported by lint(1).
673 Since this breaks the libc build itself, manual help is
674 needed -- lint must be disabled temporarily, e.g.:
675 $ (cd lib/libc && make MKLINT=no dependall install)
676
677 20080813:
678 MKDEBUG build was broken because the .depend files did not know
679 about .go files. You need to remove all .depend files and rebuild.
680
681 20080802:
682 A regression in binary compatibility for pthread_mutex_t has
683 been fixed. Unfortunately, the price is breaking compatibility
684 for -current.
685
686 Threaded programs (using libpthread) and C++ programs (using
687 libstdc++) compiled after 20070907 and before 20080802 need to
688 be recompiled.
689
690 One way to find affected pkgsrc packages:
691
692 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
693 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
694
695 20080731:
696 WAPBL (metadata journaling support) has been added, but at this
697 time isn't backwards compatible with pre-WAPBL aware kernels
698 and userland (fsck_ffs in particular). Please make sure you
699 don't use a journaled filesystem with an older kernel/userland,
700 especially an uncleanly mounted journaled filesystem. WAPBL
701 also requires the super block to be in the UFS2 format. You
702 can use fsck_ffs -c 4 to update the superblock format.
703
704 20080721:
705 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
706 isn't defined.
707
708 20080531:
709 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
710 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
711 utility needs to be rebuilt and reinstalled as older binaries
712 won't work correctly. The following sequence of commands:
713
714 $ (cd sys/sys/ && nbmake-$arch includes)
715 $ (cd sbin/drvctl/ && nbmake-$arch clean)
716 $ (cd sbin/drvctl/ && nbmake-$arch all)
717
718 leaves new drvctl utility in sbin/drvctl build directory.
719
720 20080503:
721 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
722
723 20080521:
724 For a while, unprivileged UPDATE builds would fail to
725 succeed at the checkflist stage, complaining that
726 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
727 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
728 If you already hit this problem, update the .mk file,
729 remove ${DESTDIR}/stand/<arch>, and re-run the build.
730
731 20080303:
732 Linker warnings are now fatal if $WARNS>0.
733
734 20080126:
735 The posix_fadvise system call has been changed from an assembly
736 stub, to a c file that calls an assembly stub. You need to
737 'rm -f posix_fadvise.* .depend' in the libc build directory to
738 avoid using the old assembly stub.
739
740 20071209:
741 The acpiec(4) driver has been split into two attachments. If you
742 get ACPI errors before the attachment, please update your kernel
743 configuration file appropriately or see GENERIC for more details.
744
745 20071115:
746 The it(4) driver has been renamed to itesio(4) and the old port
747 argument specified in the kernel configuration file is not valid
748 anymore. The itesio(4) driver now uses the Super I/O address port
749 rather than the EC address port. Please update your kernel
750 configuration file appropriately or see GENERIC for more details.
751
752 20071028:
753 The pccons(4) driver has been removed from the NetBSD/shark port.
754 You need to update any custom kernel configuration file you have
755 to remove any references to pccons (which includes removing the
756 now useless XSERVER option) and replace them with the correct
757 entries for the wscons driver. See the GENERIC configuration file
758 for more details.
759
760 20070913:
761 A latent bug in dhclient/dhcpd that caused it to be unable to
762 enumerate interfaces was fixed. The bug began to cause
763 problems after 20070911 when the kernel's SIOCGIFCONF
764 implementation was repaired. From 20070529 to 20070911 racoon
765 could not enumerate interfaces. (These are noted because
766 normal kernel/userspace version matching hygiene is not
767 sufficient to avoid this problem.) Ensure that both kernel
768 and userland are from after 20070913.
769
770 20070703:
771 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
772 calls the target-specific strip program, and the logic to pass
773 down STRIP from make has been removed. This requires a
774 re-installation of tools.
775
776 20070422:
777 The way OS emulations lookup filenames inside the emulation root
778 has been changed. Rather than modify the pathname (and copy back
779 to userspace) namei() and lookup() directly check the emulation
780 root. One side effect is that absolute symlinks inside the emulated
781 root file system will be relative to that file system - unless they
782 start /../ this is useful when the emulated root is a real install
783 that has such links.
784 This might affect symlinks that have been added to reference outside
785 the emulated root.
786
787 20070412:
788 The pckbc driver on sgimips IP32 has been removed. Use macekbc
789 instead. See the GENERIC32_IP3x kernel configuration for an
790 example.
791
792 20070319:
793 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
794 on many platforms due to incorrect flags settings. If you
795 updated and built after about 20070315, do "nbmake-$arch
796 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
797 rebuild of object files that might have been built
798 incorrectly, and ensure that you have at least
799 src/lib/libc/Makefile 1.130.
800
801 20070210:
802 src/sys/sys/{sa.h,savar.h} were removed.
803 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
804 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
805 will allow dependencies on those files to get get rebuilt
806
807 20070209:
808 The threading model was changed when the newlock2 branch
809 was merged to NetBSD-current. If you boot with a new
810 kernel (version 4.99.10), then you also need a new pthread
811 library (/usr/lib/libpthread.so.0.7). If you boot with
812 an old kernel, then you need the old pthread library
813 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
814 the pthread library in sync, old threaded applications should
815 continue to work with an old or new kernel. Note that named(8)
816 is the only threaded application in the base system.
817
818 20061214:
819 Following the move of string_to_flags() and flags_to_string()
820 from the bin/ls/ sources to libutil, users doing UPDATE builds
821 will need to do a "make cleandir" in
822 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
823 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
824 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
825 as the installation images in distrib/
826 in order to excise stale references to the old stat_flags.h header
827 file in the ls sources -- stat_flags.h has been removed.
828
829 20061108:
830 The configure script used in the src/tools/gcc compiler has been
831 changed to indicate that our libc has ssp support built-in and
832 does not depend on -lssp and -lssp-nonshared. You'll need to
833 make clean in src/tools/gcc first to rebuild the compiler.
834
835 20061009:
836 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
837 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
838
839 20060814:
840 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
841 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
842 kernel configuration for an example. X servers from the last
843 few years should cope.
844
845 20060703:
846 MPACPI is no more. We always configure PCI interrupts using ACPI
847 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
848 to ACPI_SCANPCI. Thanks to work from fvdl.
849
850 20060627:
851 socket(2) has changed, and its system call has been versioned.
852 For userlands with the old version of socket(2), make sure that
853 your kernel has 'options COMPAT_30' set, or else 'bad system call'
854 errors will result.
855
856 Hints for a more successful build:
857 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
858 Use build.sh, but do not use its "expert mode":
859 This will automatically build the tools in the
860 correct order, and it will keep the tools and the
861 new build products from interfering with the running
862 system. This will allow you to ignore most of the
863 other advice in this file.
864 Build a new kernel first:
865 This makes sure that any new system calls or features
866 expected by the new userland will be present. This
867 helps to avoid critical errors when upgrading.
868 Use object directories:
869 This helps to keep stale object
870 files from polluting the build if a Makefile "forgets"
871 about one. It also makes it easier to clean up after
872 a build. It's also necessary if you want to use the
873 same source tree for multiple machines.
874 To use object directories with build.sh:
875 a) invoke build.sh with the "-M" or "-O" options.
876 To use object directories without using build.sh:
877 a) cd /usr/src ; make cleandir
878 b) Add "OBJMACHINE=yes" to /etc/mk.conf
879 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
880 d) cd /usr/src ; make build
881 Note that running "make obj" in a directory will create
882 in obj.$MACHINE directory.
883 Build to a DESTDIR:
884 This helps to keep old installed files (especially libraries)
885 from interfering with the new build.
886 To build to a DESTDIR with build.sh, use the "-D" option.
887 To build to a DESTDIR without using build.sh, set the DESTDIR
888 environment variable before running make build. It should be
889 set to the pathname of an initially empty directory.
890 Problems: if you do not use build.sh, you might need to
891 update critical utilities without using DESTDIR since
892 nothing is executed from what is installed in DESTDIR.
893 (See critical utils, below.)
894 Build often:
895 This keeps critical utilities current enough to not choke
896 on any other part of the source tree that depends on up to
897 date functionality. If you use build.sh, you should not have
898 this problem.
899
900 What to do if things don't work:
901 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
902 When things don't work there are usually a few things that commonly
903 should be done.
904 1) make includes
905 This should be done automatically by make build.
906 2) cd share/mk && make install
907 Again, automatically done by make build.
908
909 Failsafe rebuild of a small part of the tree:
910 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
911 To make sure you rebuild something correctly you want to do
912 something like the following:
913 1) Make sure the includes and .mk files are up to date.
914 2) Make sure any program used to build the particular
915 utility is up to date. (yacc, lex, etc...)
916 3) cd ...path/to/util...
917 make cleandir
918 rm ...all obj directories...
919 make cleandir # yes, again
920 make obj
921 make depend && make
922
923 Failsafe rebuild of the entire tree:
924 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
925 If you really want to make sure the source tree is clean and
926 ready for a build try the following. Note that sourcing /etc/mk.conf
927 (a make(1) Makefile) in this manner is not right, and will not work
928 for anyone who uses any make(1) features in /etc/mk.conf.
929

989 (If you built the tree without "make obj" in the past, obsolete files
990 may remain. The command tries to clean everything up)

1015 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
1016 No such file or directory.
1017 Cause: If a directory is created by mistake, then it is sometimes
1018 deleted from the CVS repository using administrative commands
1019 that bypass the normal cvs access controls. If your cvs working tree
1020 contains references to a directory that has been deleted on the
1021 server in this way, then "cvs update" reports this error.
1022 Fix: Recursively delete the affected directory from your working tree
1023 and try the update again.
