UPDATING revision 1.316 1 $NetBSD: UPDATING,v 1.316 2020/10/17 07:41:25 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 20201016:
23 MIPS kernel modules have been disabled until they work. This will
24 turn up in extra files in the DESTDIR, which should be cleaned.
25
26 20200925:
27 GNU MPC and MPFR have been updated. At least MPFR needs cleaning
28 in both the tools and external dirs.
29
30 20200912:
31 GCC 9 has arrived for Arm and x86 platforms, and will be coming
32 for several more, as will binutils 2.34. Clean as required.
33
34 20200907:
35 GCC 9 is coming, and binutils has been updated for MIPS. This
36 probably requires cleaning the tools/binutils.
37
38 20200811:
39 GCC updates may require cleaning the objdir. This may occur
40 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming
41 GCC 9 upgrade.
42
43 20200614:
44 blacklist* has been renamed to blocklist*. postinstall(8)
45 should handle the migration
46
47 20200601:
48 Due to a mistake in LIBISPRIVATE handling, .so libraries were
49 created in the build directories and need cleaning.
50
51 20200311:
52 GCC 8 ports will need cleaning in src/tools/gcc and
53 src/external/gpl3/gcc due to GCC 8.4 update.
54
55 20191118:
56 More architectures were switched to gcc8:
57 i386, ia64 powerpc64, sparc, sparc64, arm
58 The same comments as in 20191022 apply.
59
60 20191112:
61 The LLVM update requires a clean rebuild for all architectures using
62 LLVM during the tools build phase (i386, amd64, aarch64).
63
64 20191022:
65 Ports amd64 and aarch64 switched to GCC 8.3 by default.
66 In-place ("expert mode", build.sh -E) builds are not supported
67 when going from a GCC 7 userland to GCC 8. Do a regular
68 build to a different DESTDIR (or preferably: build.sh -U) at least
69 once and install sets, or download comp.{tar.xz,tgz} from the
70 daily builds and install that before doing the next in-place build.
71
72 20191001:
73 GCC 8.3 was imported. Builds of src/tools/gcc may fail if
74 old builds with GCC 7 output now uses GCC 8. Clean this
75 directory, and also clean src/external/gpl3/gcc.
76
77 20190903:
78 Files with names that coincide with existing files' names on
79 case-insensitive file systems were inadvertently committed, for
80 radeon GPU firmware. We cannot mark these as obsolete for
81 postinstall to fix, so if you updated src since 2019-08-26, and
82 ran build.sh distribution or ran build.sh release, you must
83 manually delete the following files in your DESTDIR (which is
84 usually $OBJDIR/destir.$ARCH), or from / if you have installed
85 them:

154 We will re-import these radeon firmware images another way
155 later.
156
157 20190727:
158 The uefi bootloader has gained tftp support and needs a clean
159 build. If you do update builds, manually clean its object
160 directory by something like:
161 cd sys/arch/i386/stand/efiboot && make clean
162
163 20190723:
164 The jemalloc allocator in libc is now build without extended
165 debugging (for performance reasons). In update builds make sure
166 to rebuild it completly, by removing all affected object files,
167 including compat builds, something like:
168 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
169
170 20190207:
171 GCC 7 switched for many ports. Update builds are likely to fail.
172
173 20180924:
174 A newer OpenSSL version has been imported. If you are doing
175 update builds, make sure to remove all old obj dirs, like:
176 cd /usr/obj && find . -type d -name openssl | xargs rm -rf
177
178 20180717:
179 On aarch64 int64_t and related types have changed from long long
180 to long. This requires recompiling all C++ binaries.
181
182 20180713:
183 On amd64 and i386 static binaries are now build position
184 independend. This requires recompilation of all object
185 files used to create the crunched /rescue binary.
186 Clean the rescue directory in your obj directory before
187 doing an update build, otherwise linking will fail.
188
189 20180414:
190 Existing binutils was migrated to binutils.old. Manual
191 removal of tools/binutils objects directory may be required
192 to fix tools build failure.
193
194 20180311:
195 bdftopcf was updated and may need cleaning in the
196 src/external/mit/xorg/tools/bdftopcf subdirectory if there are
197 link errors.
198
199 20180212:
200 between OpenSSL and GCC updates, many things may fail to build.
201 any failure that looks like GCC or openssl is best handled by
202 a clean destdir and objdir. Full cleandir and destdir deletion
203 is recommended if build failures occur.
204
205 20171225:
206 removal of the vadvise syscall requires manual removal of all
207 associated files from the libc build object directory (including
208 the .depend files) - a command like:
209 cd $OBJ && find . -type d -name libc | xargs rm -rf
210 For architectures that support multiple "compat" binary targets,
211 you'll need to cleanup both the regular libc directory and the
212 compat ones (the above command will do that).
213
214 20171010:
215 a change to the build structure of external/bsd/acpica/bin/iasl
216 means that its objdir (or *.d and .depend at least) might need
217 to be manually removed - or a build done once without -u.
218
219 20170822:
220 a new version of GMP has been imported and probably
221 will break parts of builds related to themselves or GCC, both
222 in the tools and the native section. Remove all GCC, GMP, MPFR
223 and MPC objdirs or build once without -u.
224
225 20170816:
226 a new version of MPFR and MPC have been imported and probably
227 will break parts of builds related to themselves or GCC, both
228 in the tools and the native section. Remove all GCC, GMP, MPFR
229 and MPC objdirs or build once without -u.
230
231 20170402:
232 a new version of dhcpcd has been imported, which does not support
233 update builds from the previous version. Remove your
234 external/bsd/dhcpcd object dir or build once without -u.
235
236 20170211:
237 a new terminfo database has been imported.
238 The structure of it has changed slightly from prior versions and
239 an updated tic tool is required.
240 If you build.sh, don't use -u
241
242 20170207:
243 various arch dependent libc/exect.S files were removed
244 Either remove the obj directories (lib/libc and compat/amd64/i386/lib
245 if it exists) or do a clean build.
246 (This is a bug in the make system, it should be corrected without
247 human intervention, but isn't.)
248
249 20170104:
250 xinput build options have changed.
251 Remove the obj directory (external/mit/xorg/bin/xinput)
252 if you build.sh -u
253
254 20170103:
255 a new version of flex has been imported.
256 Remove the file from obj (external/bsd/flex)
257 if you build.sh -u
258
259 20161014:
260 a new version of OpenSSL has been imported.
261 Remove the files from obj (crypto/external/bsd/openssl)
262 if you build.sh -u
263
264 20161009:
265 a new version of dhcpcd has been imported with slightly changed
266 build infrastructure. When doing a build.sh -u this requires
267 pruning the external/bsd/dhcpcd objdir.
268
269 20160914:
270 i386, amd64, shark, ofppc and macppc have joined shark and x68k
271 ports in using xorg-server 1.18. This requires a clean destdir
272 and a clean objdir.
273
274 20160527:
275 i386 needs a full cleandir or objdir deletion because PIE has
276 been enabled. (see the amd64 entry two down for further info)
277
278 20160418:
279 libedit needs manual removal of all autogenerated files since
280 some of them are not autogenerated anymore. Remember that there
281 might be two copies of libedit if your platform builds "compat".
282
283 20160410:
284 amd64 needs full "make cleandir" or deletion of objdir now that
285 PIE has been enabled for amd64. PIE, or position-independent
286 executables, means all code, including executables and not just
287 shared libraries, is position-independent and hence able to be
288 relocated by ASLR, address space layout randomization.
289
290 The change was made in Makefile variables for compiler and
291 linker flags, for which make(1) does not record dependencies,
292 hence it is unable to detect that all .o files need rebuilding.
293
294 Partial rebuilds with some modified source files will likely
295 fail when linking executables, since the linker refuses to mix
296 position-independent code with position-dependent code in
297 position-independent executables:
298
299 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
300
301 20160401:
302 Ports switching to GCC 5.3 will need a full "make cleandir".
303 Some people have found that cleandir is not sufficient, so if
304 in doubt delete the entire object directory tree for gcc.
305
306 20160306:
307 NetBSD's regexp implementation is now part of libnbcompat.
308 Nblex, nbm4, nbpax, nbsed use it and they may crash on
309 non-NetBSD hosts if linked with stale object files produced
310 while they included a non-NetBSD regex.h.
311 In any case, you should "make cleandir" at least these tools
312 before updating your toolchain.
313
314 20160125:
315 Dtrace has been enabled by default on some architectures.
316 When doing an update build, make sure to clean the etc/mtree
317 object directory before starting the build - otherwise the
318 needed directories in destdir will not be created.
319 An easy way to do this is:
320 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
321
322 20150818:
323 New acpica requires "make cleandir" in src/external/bsd/acpica
324 again.
325
326 20150413:
327 New acpica requires "make cleandir" and reinstalling yacc
328 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
329 also "make cleandir" in /usr/src/external/bsd/acpica.
330
331 20150404:
332 Lint changes require a full rebuild of the tool, so make
333 sure to build without -u option to build.sh, or manually
334 do a make cleandir in src/tools/lint1 and
335 src/usr.bin/xlint.
336
337 20150310:
338 Improvements to openssl for arm mean that update builds of
339 the openssl libraries will fail. A make cleandir in
340 external/bsd/openssl/lib is needed
341
342 20141026:
343 A mishap during the import of pppd may cause your corruption
344 in your cvs directory if you happened to do a cvs update
345 during a short period of time. To fix, just remove the
346 directory src/external/bsd/ppp/dist/pppd completely
347 and let cvs restore it on next update.
348
349 20140721:
350 The src/external/mit/lua/src directory was accidentally created
351 and then deleted in the CVS repository. If you get errors like
352
353 cvs [update aborted]: cannot open directory
354 /cvsroot/src/external/mit/lua/src: No such file or directory
355
356 then delete your local copy of that directory tree and try again.
357
358 20140530:
359 ARM eABI switched to DWARF based exception handling. This requires
360 rebuilding all C++ code. It is strongly advised to do a clean build.
361
362 20140131:
363 The new compiler_rt/libc integration moved a few things. It is strongly
364 advised to do a clean build. At least lib/libc, the compat version(s)
365 of libc, libkern, rump and the kernels need to be cleaned.
366
367 20131227:
368 1. The new ntpd runs in a restricted mode to prevent amplification
369 attacks. If you need ntpdc to work you need to explicitly enable
370 mode7 in your config file. Make sure you put the necessary restrict
371 statements to avoid being exposed.
372 2. strncat has moved from lib/libc to common/lib/libc; you might need
373 to make clean in libc
374
375 20131129:
376 The GMP sources were updated, and builds will likely fail without
377 cleaning their build trees for both tools and in-tree, like below.
378
379 20131128:
380 The MPC and MPFR sources were updated, and builds may require their
381 tools and in-tree directories cleaned for successful updates.
382
383 20130605:
384 The kernel option FAST_IPSEC no longer exists, it's been renamed
385 to IPSEC (and the older IPSEC version removed).
386
387 20130605:
388 Previous freetype installations eroneously installed private
389 header files. If you are building against a non-empty $DESTDIR,
390 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
391
392 20130531:
393 The xdm update may cause build failure due to xdm.man being
394 in the obj tree. Make sure to ensure any like this:
395 nbmake: nbmake: don't know how to make xdm.man. Stop
396 is fixed by deleting the xdm.man in the obj tree.
397
398 20130530:
399 Updates of many xsrc packages will leave old .pc files around.
400 Best to clean out the xsrc objdir entirely before rebuilds.
401
402 20130301:
403 The removal of netiso requires manual removal of /usr/include/netiso
404 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
405
406 20120726:
407 The update of OpenSSL requires cleaning both the OpenSSL build
408 directory and DESTDIR. *Even non-update builds require cleaning
409 DESTDIR.* Builds done without taking these steps may fail, or in
410 some cases may succeed and install broken OpenSSL libraries that
411 cause third-party software to link incorrectly and/or crash.
412
413 20120507:
414 The database schema for makemandb was changed. You will
415 need to update the database using 'makemandb -f' or wait
416 for the next weekly run to fix it.
417
418 20120319:
419 sys/conf/Makefile.kern.inc has been modified to adjust the
420 size of db_symtab automatically. You need to update dbsym in
421 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
422 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
423 mk.conf.
424
425 20120216:
426 Default for MKCATPAGES changed to NO. Update builds will fail
427 unless DESTDIR is cleaned manually. If you built between 20120207
428 and 20120216, daily and weekly could have created an unreadable
429 /var/db/man.db index for apropos. Running makemandb -f or
430 the next run of weekly will fix it.
431
432 20111227:
433 If you built between 20111225 and 20111227 you need to remove
434 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
435 bump has been reverted.
436
437 20111125:
438 The "rnd" pseudodevice has been added to sys/conf/std, which
439 means it should no longer be explicitly listed in kernel
440 configuration files. The line "pseudo-device rnd" should be
441 removed from any custom kernel config files users may have.
442
443 20111119:
444 A problem with the datastructures used by the rndctl(8)
445 utility (pointers in datastructures in an array, making 32->64
446 bit compatibility very painful) has been fixed in a
447 non-backwards-compatible way. If you replace your kernel,
448 replace your rndctl executable too.
449
450 20111001:
451 the prop_*_send_syscall() functions from proplib(3) have been
452 changed and their new version is not backward compatible with the old
453 one. So ensure that all consumers of these functions (currently:
454 quota2 code and its tests) are updated together with the new lib.
455
456 20110817:
457 sparc has been changed to use GCC 4.5.3, so any objdir or
458 DESTDIR for them should be deleted before updating.
459
460 20110806:
461 i386 and amd64 have been changed to use GCC 4.5.3, so any
462 objdir or DESTDIR for them should be deleted before updating.
463
464 20110805:
465 The update to GCC 4.5.3 requires a non-trivial portion of
466 the tree to be cleaned. Best to delete both objdir and
467 DESTDIR before running this update. So far, only the
468 sparc64, mips and powerpc platforms have changed.
469
470 20110803:
471 The layout of external/public-domain/xz has changed. To do an
472 update build you will have to remove the contents of the OBJDIR
473 for external/public-domain/xz/bin by hand as the xz entry there
474 is now a directory.
475
476 20110410:
477 The configuration of src/tools/gcc has changed. To do an
478 update build you have to clean both tools/binutils and
479 tools/gcc by hand.
480
481 20110328:
482 Building the Xorg binary was moved into a subdirectory to fix
483 ordering issues with "make all". It may be necessary to remove
484 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
485 if your update build fails, as the "Xorg" entry there is now a
486 directory.
487
488 20110121:
489 Assembler files no longer use -traditional-cpp. This can break
490 the build of individual parts of the tree. This is handled
491 correctly by build.sh. Manual builds have to update /usr/share/mk
492 and re-run config(1) for any kernel configurations as needed.
493
494 20101217:
495 The tcpdump(8) program was changed to drop privileges and chroot(2)
496 by default. It may be necessary to manually update passwd(5) and
497 group(5) in order to make the program work with existing setups.
498
499 20101125:
500 The latest changes to setenv(3) dissallow setting environment
501 variables with names that contain '='. Revision 1.18 of env.c
502 assumed that this was allowed. Installing a new libc with an
503 old copy of /usr/bin/env causes env x=1 printenv | grep x= to
504 break which affects the autoconf tests for dependency finding,
505 so building gcc will end up printing:
506 checking dependency style of gcc... none
507 configure: error: no usable dependency style found
508 Fix it by rebuilding and re-installing env.
509
510 20101119:
511 Recent Xorg updates in xsrc/external/mit/ may cause various build
512 or run-time problems. Delete your entire DESTDIR and OBJDIR if you
513 have any build problems with xsrc, or problems with mismatched
514 versions between xorg-server and drivers.
515
516 20100604:
517 The update of ATF to 0.9 causes old tests written in shell to fail
518 unless they are rebuilt. If you are building with MKUPDATE=yes,
519 you need to clean the src/external/bsd/atf/tests/ and the src/tests/
520 trees by hand.
521
522 20100522:
523 Recent Xorg updates in xsrc/external/mit/ will cause various build
524 problems. Delete your entire DESTDIR and OBJDIR if you have any
525 build problems with xsrc.
526
527 20100522:
528 private section of <ctype.h> was splitted, and now mklocale(1)
529 include ctype_local.h, so you have to make cleandir in tools/mklocale.
530
531 20100520:
532 The location of the xkb compiled descriptions has changed. Please
533 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
534
535 20100222:
536 The shared objects file extension has been changed from .so to
537 .pico, in order to avoid conflicts with shared libraries names
538 libXX.so. All now stale regular .so files can be removed from
539 your object directories.
540
541 20100204:
542 The termcap database has been removed from the sources,
543 but has not been marked obsolete so it is not removed
544 from the system when upgrading.
545 As such, you will need to remove them from your object
546 and destination directories.
547
548 20091101:
549 After updating, it may be necessary to make the 'cleandir'
550 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
551 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
552 src/tools/lex/ and src/usr.bin/lex/.
553
554 20091001:
555 On amd64 you must rebuild tools (to get the new binutils)
556 before building a kernel, or the build fails on cpufunc.S.
557
558 20091001:
559 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
560 symlink, failing the build. Delete the link, and the subdir
561 it is in, and retry your build.
562
563 20090718:
564 libc build changed so that strchr() provides the extra entry
565 point for index(). Update build of libc.a (and libc_pic.a)
566 may fail because the archive contains the unwanted index.o.
567 (Similarly for strrchr() and rindex().)
568
569 20090709:
570 Native Xorg was upgraded again. Builds will probably fail again
571 without a clean objdir, at least for src/external/mit/xorg.
572
573 20090616:
574 Native Xorg was upgraded. Builds will need a clean objdir for
575 src/external/mit/xorg. Upgrading a system from sets will not
576 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
577 subdirectory has been changed into a file, and this needs to
578 be manually "rm -r"'ed before installing xbase.tgz.
579
580 20090501:
581 Several new functions were added to string.h/libc, and this
582 can cause autoconf problems during the tool build for people
583 who fail to clean out their tools objects properly. If you
584 note messages about stpcpy, stpncpy or strnlen accompanying a
585 failure during the tool build, clean out all your tools
586 objects and start again.
587
588 20090325:
589 The i386 port was switched to i486 default toolchain. This requires
590 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
591
592 20090126:
593 The __posix_fadvise50 system call changed assembly stub type. You
594 need to 'rm -f __posix_fadvise50.*' in the libc build directory
595 to avoid using the old assembly stub.
596
597 20090202:
598 pkg_install now depends on the pkgdb cache for automatic conflict
599 detection. It is recommented to rebuild the cache with
600 ``pkg_admin rebuild''.
601
602 20090110:
603 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
604 1. Make sure your kernel has COMPAT_50 in it. Build and install.
605 This is needed even in the MODULAR kernel because there is
606 conditionally compiled code in rtsock.c.
607 2. make sure build.sh completes and the binaries in a chroot work
608 before installing.
609 3. If you don't use build.sh and you build directly to root, and
610 your build breaks in the middle, don't despair. Make sure headers
611 are installed properly, and start building libraries first libc
612 and libutil, install them and then continue building all the
613 libraries in src/lib and src/gnu/lib and install them. Once
614 the new libraries are installed, you can restart the build.
615 4. If you compile packages and you notice link time warnings,
616 rebuild the required packages to update their shared libraries.
617 Any package you rebuild will require rebuilding all the packages
618 that depend on it.
619 5. Next time you run pwd_mkdb with the new binary, the file
620 will be upgraded and it will not be backwards compatible.
621 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
622 lastlogx(5)) have been versioned, and there is a heuristic
623 for utmp. You are better off removing the old files after
624 upgrading. The automated clearing of /var/run during
625 boot, and the automated rotating of files in /var/log by
626 newsyslog(8), may mean that you do not have to remove the
627 files manually.
628 7. The optional accounting file (/var/account/acct, see
629 accton(8)) has not been versioned, and will need to be
630 removed. The automatic rotation of the accounting file by
631 /etc/daily limits the bad consequences of failure to remove
632 the file.
633 8. Application software that writes time_t to binary files on
634 disk will break or need attention. Most notably: if you are
635 using PostgreSQL < 8.4, you need to dump your databases,
636 rebuild PostgreSQL with the new time_t, then restore.
637
638 20081219:
639 config(1) has been updated, and one of the files it creates -
640 swapnetbsd.o - has changed format. You need to rebuild config
641 (done automatically by build.sh) and then you need to rerun
642 config on all kernel configuration files before rebuilding those
643 kernels.
644
645 20081205:
646 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
647 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
648 set and will appear as extra files for MKX11=no update builds.
649
650 20081122:
651 On i386, various kernel options(4) in GENERIC including
652 file systems have been disabled and moved into kernel modules.
653 Before trying a new GENERIC kernel, you have to prepare the
654 following files as well as a new GENERIC kernel:
655
656 - build and install kernel modules from src/sys/modules
657
658 - install the latest bootloader, which will load a module
659 for the file system from which the kernel is loaded automatically
660
661 If you have to load your kernel from a file system which is not of
662 the same type as the root file system, you have to load the necessary
663 file system module manually on the boot prompt or in the boot.cfg file.
664
665 20080827:
666 If you built and installed a libc from sources between
667 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
668 which results in false errors reported by lint(1).
669 Since this breaks the libc build itself, manual help is
670 needed -- lint must be disabled temporarily, e.g.:
671 $ (cd lib/libc && make MKLINT=no dependall install)
672
673 20080813:
674 MKDEBUG build was broken because the .depend files did not know
675 about .go files. You need to remove all .depend files and rebuild.
676
677 20080802:
678 A regression in binary compatibility for pthread_mutex_t has
679 been fixed. Unfortunately, the price is breaking compatibility
680 for -current.
681
682 Threaded programs (using libpthread) and C++ programs (using
683 libstdc++) compiled after 20070907 and before 20080802 need to
684 be recompiled.
685
686 One way to find affected pkgsrc packages:
687
688 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
689 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
690
691 20080731:
692 WAPBL (metadata journaling support) has been added, but at this
693 time isn't backwards compatible with pre-WAPBL aware kernels
694 and userland (fsck_ffs in particular). Please make sure you
695 don't use a journaled filesystem with an older kernel/userland,
696 especially an uncleanly mounted journaled filesystem. WAPBL
697 also requires the super block to be in the UFS2 format. You
698 can use fsck_ffs -c 4 to update the superblock format.
699
700 20080721:
701 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
702 isn't defined.
703
704 20080531:
705 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
706 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
707 utility needs to be rebuilt and reinstalled as older binaries
708 won't work correctly. The following sequence of commands:
709
710 $ (cd sys/sys/ && nbmake-$arch includes)
711 $ (cd sbin/drvctl/ && nbmake-$arch clean)
712 $ (cd sbin/drvctl/ && nbmake-$arch all)
713
714 leaves new drvctl utility in sbin/drvctl build directory.
715
716 20080503:
717 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
718
719 20080521:
720 For a while, unprivileged UPDATE builds would fail to
721 succeed at the checkflist stage, complaining that
722 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
723 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
724 If you already hit this problem, update the .mk file,
725 remove ${DESTDIR}/stand/<arch>, and re-run the build.
726
727 20080303:
728 Linker warnings are now fatal if $WARNS>0.
729
730 20080126:
731 The posix_fadvise system call has been changed from an assembly
732 stub, to a c file that calls an assembly stub. You need to
733 'rm -f posix_fadvise.* .depend' in the libc build directory to
734 avoid using the old assembly stub.
735
736 20071209:
737 The acpiec(4) driver has been split into two attachments. If you
738 get ACPI errors before the attachment, please update your kernel
739 configuration file appropriately or see GENERIC for more details.
740
741 20071115:
742 The it(4) driver has been renamed to itesio(4) and the old port
743 argument specified in the kernel configuration file is not valid
744 anymore. The itesio(4) driver now uses the Super I/O address port
745 rather than the EC address port. Please update your kernel
746 configuration file appropriately or see GENERIC for more details.
747
748 20071028:
749 The pccons(4) driver has been removed from the NetBSD/shark port.
750 You need to update any custom kernel configuration file you have
751 to remove any references to pccons (which includes removing the
752 now useless XSERVER option) and replace them with the correct
753 entries for the wscons driver. See the GENERIC configuration file
754 for more details.
755
756 20070913:
757 A latent bug in dhclient/dhcpd that caused it to be unable to
758 enumerate interfaces was fixed. The bug began to cause
759 problems after 20070911 when the kernel's SIOCGIFCONF
760 implementation was repaired. From 20070529 to 20070911 racoon
761 could not enumerate interfaces. (These are noted because
762 normal kernel/userspace version matching hygiene is not
763 sufficient to avoid this problem.) Ensure that both kernel
764 and userland are from after 20070913.
765
766 20070703:
767 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
768 calls the target-specific strip program, and the logic to pass
769 down STRIP from make has been removed. This requires a
770 re-installation of tools.
771
772 20070422:
773 The way OS emulations lookup filenames inside the emulation root
774 has been changed. Rather than modify the pathname (and copy back
775 to userspace) namei() and lookup() directly check the emulation
776 root. One side effect is that absolute symlinks inside the emulated
777 root file system will be relative to that file system - unless they
778 start /../ this is useful when the emulated root is a real install
779 that has such links.
780 This might affect symlinks that have been added to reference outside
781 the emulated root.
782
783 20070412:
784 The pckbc driver on sgimips IP32 has been removed. Use macekbc
785 instead. See the GENERIC32_IP3x kernel configuration for an
786 example.
787
788 20070319:
789 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
790 on many platforms due to incorrect flags settings. If you
791 updated and built after about 20070315, do "nbmake-$arch
792 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
793 rebuild of object files that might have been built
794 incorrectly, and ensure that you have at least
795 src/lib/libc/Makefile 1.130.
796
797 20070210:
798 src/sys/sys/{sa.h,savar.h} were removed.
799 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
800 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
801 will allow dependencies on those files to get get rebuilt
802
803 20070209:
804 The threading model was changed when the newlock2 branch
805 was merged to NetBSD-current. If you boot with a new
806 kernel (version 4.99.10), then you also need a new pthread
807 library (/usr/lib/libpthread.so.0.7). If you boot with
808 an old kernel, then you need the old pthread library
809 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
810 the pthread library in sync, old threaded applications should
811 continue to work with an old or new kernel. Note that named(8)
812 is the only threaded application in the base system.
813
814 20061214:
815 Following the move of string_to_flags() and flags_to_string()
816 from the bin/ls/ sources to libutil, users doing UPDATE builds
817 will need to do a "make cleandir" in
818 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
819 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
820 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
821 as the installation images in distrib/
822 in order to excise stale references to the old stat_flags.h header
823 file in the ls sources -- stat_flags.h has been removed.
824
825 20061108:
826 The configure script used in the src/tools/gcc compiler has been
827 changed to indicate that our libc has ssp support built-in and
828 does not depend on -lssp and -lssp-nonshared. You'll need to
829 make clean in src/tools/gcc first to rebuild the compiler.
830
831 20061009:
832 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
833 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
834
835 20060814:
836 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
837 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
838 kernel configuration for an example. X servers from the last
839 few years should cope.
840
841 20060703:
842 MPACPI is no more. We always configure PCI interrupts using ACPI
843 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
844 to ACPI_SCANPCI. Thanks to work from fvdl.
845
846 20060627:
847 socket(2) has changed, and its system call has been versioned.
848 For userlands with the old version of socket(2), make sure that
849 your kernel has 'options COMPAT_30' set, or else 'bad system call'
850 errors will result.
851
852 Hints for a more successful build:
853 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
854 Use build.sh, but do not use its "expert mode":
855 This will automatically build the tools in the
856 correct order, and it will keep the tools and the
857 new build products from interfering with the running
858 system. This will allow you to ignore most of the
859 other advice in this file.
860 Build a new kernel first:
861 This makes sure that any new system calls or features
862 expected by the new userland will be present. This
863 helps to avoid critical errors when upgrading.
864 Use object directories:
865 This helps to keep stale object
866 files from polluting the build if a Makefile "forgets"
867 about one. It also makes it easier to clean up after
868 a build. It's also necessary if you want to use the
869 same source tree for multiple machines.
870 To use object directories with build.sh:
871 a) invoke build.sh with the "-M" or "-O" options.
872 To use object directories without using build.sh:
873 a) cd /usr/src ; make cleandir
874 b) Add "OBJMACHINE=yes" to /etc/mk.conf
875 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
876 d) cd /usr/src ; make build
877 Note that running "make obj" in a directory will create
878 in obj.$MACHINE directory.
879 Build to a DESTDIR:
880 This helps to keep old installed files (especially libraries)
881 from interfering with the new build.
882 To build to a DESTDIR with build.sh, use the "-D" option.
883 To build to a DESTDIR without using build.sh, set the DESTDIR
884 environment variable before running make build. It should be
885 set to the pathname of an initially empty directory.
886 Problems: if you do not use build.sh, you might need to
887 update critical utilities without using DESTDIR since
888 nothing is executed from what is installed in DESTDIR.
889 (See critical utils, below.)
890 Build often:
891 This keeps critical utilities current enough to not choke
892 on any other part of the source tree that depends on up to
893 date functionality. If you use build.sh, you should not have
894 this problem.
895
896 What to do if things don't work:
897 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
898 When things don't work there are usually a few things that commonly
899 should be done.
900 1) make includes
901 This should be done automatically by make build.
902 2) cd share/mk && make install
903 Again, automatically done by make build.
904
905 Failsafe rebuild of a small part of the tree:
906 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
907 To make sure you rebuild something correctly you want to do
908 something like the following:
909 1) Make sure the includes and .mk files are up to date.
910 2) Make sure any program used to build the particular
911 utility is up to date. (yacc, lex, etc...)
912 3) cd ...path/to/util...
913 make cleandir
914 rm ...all obj directories...
915 make cleandir # yes, again
916 make obj
917 make depend && make
918
919 Failsafe rebuild of the entire tree:
920 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
921 If you really want to make sure the source tree is clean and
922 ready for a build try the following. Note that sourcing /etc/mk.conf
923 (a make(1) Makefile) in this manner is not right, and will not work
924 for anyone who uses any make(1) features in /etc/mk.conf.
925

957 usr.bin/config
958
959 Other problems and possible solutions:
960 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
961 Symptom:Complaints involving a Makefile.
962 Fix: Rebuild usr.bin/make:
963 cd usr.bin/make && make && make install
964 Or, a failsafe method if that doesn't work:
965 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
966
967 Fix: Make sure .mk files are up to date.
968 cd share/mk && make install
969
970 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
971 Fix: Rebuild usr.bin/config
972
973 Symptom:
974 Fix: Rebuild usr.bin/yacc
975
976 Symptom:
977 Fix: Rebuild usr.bin/lex
978
979 Symptom:
980 Fix: rm /usr/lib/libbfd.a
981
982 Symptom:Obsolete intermediate files are used during compilation
983 Fix: Try the following sequence of commands in the directory in question.
984 make cleandir; rm `make print-objdir`; make cleandir; make obj
985 (If you built the tree without "make obj" in the past, obsolete files

1011 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
1012 No such file or directory.
1013 Cause: If a directory is created by mistake, then it is sometimes
1014 deleted from the CVS repository using administrative commands
1015 that bypass the normal cvs access controls. If your cvs working tree
1016 contains references to a directory that has been deleted on the
1017 server in this way, then "cvs update" reports this error.
1018 Fix: Recursively delete the affected directory from your working tree
1019 and try the update again.
