UPDATING revision 1.314 1 $NetBSD: UPDATING,v 1.314 2020/09/12 08:31:39 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 20200912:
23 GCC 9 has arrived for Arm and x86 platforms, and will be coming
24 for several more, as will binutils 2.34. Clean as required.
25
26 20200907:
27 GCC 9 is coming, and binutils has been updated for MIPS. This
28 probably requires cleaning the tools/binutils.
29
30 20200811:
31 GCC updates may require cleaning the objdir. This may occur
32 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming
33 GCC 9 upgrade.
34
35 20200614:
36 blacklist* has been renamed to blocklist*. postinstall(8)
37 should handle the migration
38
39 20200601:
40 Due to a mistake in LIBISPRIVATE handling, .so libraries were
41 created in the build directories and need cleaning.
42
43 20200311:
44 GCC 8 ports will need cleaning in src/tools/gcc and
45 src/external/gpl3/gcc due to GCC 8.4 update.
46
47 20191118:
48 More architectures were switched to gcc8:
49 i386, ia64 powerpc64, sparc, sparc64, arm
50 The same comments as in 20191022 apply.
51
52 20191112:
53 The LLVM update requires a clean rebuild for all architectures using
54 LLVM during the tools build phase (i386, amd64, aarch64).
55
56 20191022:
57 Ports amd64 and aarch64 switched to GCC 8.3 by default.
58 In-place ("expert mode", build.sh -E) builds are not supported
59 when going from a GCC 7 userland to GCC 8. Do a regular
60 build to a different DESTDIR (or preferably: build.sh -U) at least
61 once and install sets, or download comp.{tar.xz,tgz} from the
62 daily builds and install that before doing the next in-place build.
63
64 20191001:
65 GCC 8.3 was imported. Builds of src/tools/gcc may fail if
66 old builds with GCC 7 output now uses GCC 8. Clean this
67 directory, and also clean src/external/gpl3/gcc.
68
69 20190903:
70 Files with names that coincide with existing files' names on
71 case-insensitive file systems were inadvertently committed, for
72 radeon GPU firmware. We cannot mark these as obsolete for
73 postinstall to fix, so if you updated src since 2019-08-26, and
74 ran build.sh distribution or ran build.sh release, you must
75 manually delete the following files in your DESTDIR (which is
76 usually $OBJDIR/destir.$ARCH), or from / if you have installed
77 them:

146 We will re-import these radeon firmware images another way
147 later.
148
149 20190727:
150 The uefi bootloader has gained tftp support and needs a clean
151 build. If you do update builds, manually clean its object
152 directory by something like:
153 cd sys/arch/i386/stand/efiboot && make clean
154
155 20190723:
156 The jemalloc allocator in libc is now build without extended
157 debugging (for performance reasons). In update builds make sure
158 to rebuild it completly, by removing all affected object files,
159 including compat builds, something like:
160 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
161
162 20190207:
163 GCC 7 switched for many ports. Update builds are likely to fail.
164
165 20180924:
166 A newer OpenSSL version has been imported. If you are doing
167 update builds, make sure to remove all old obj dirs, like:
168 cd /usr/obj && find . -type d -name openssl | xargs rm -rf
169
170 20180717:
171 On aarch64 int64_t and related types have changed from long long
172 to long. This requires recompiling all C++ binaries.
173
174 20180713:
175 On amd64 and i386 static binaries are now build position
176 independend. This requires recompilation of all object
177 files used to create the crunched /rescue binary.
178 Clean the rescue directory in your obj directory before
179 doing an update build, otherwise linking will fail.
180
181 20180414:
182 Existing binutils was migrated to binutils.old. Manual
183 removal of tools/binutils objects directory may be required
184 to fix tools build failure.
185
186 20180311:
187 bdftopcf was updated and may need cleaning in the
188 src/external/mit/xorg/tools/bdftopcf subdirectory if there are
189 link errors.
190
191 20180212:
192 between OpenSSL and GCC updates, many things may fail to build.
193 any failure that looks like GCC or openssl is best handled by
194 a clean destdir and objdir. Full cleandir and destdir deletion
195 is recommended if build failures occur.
196
197 20171225:
198 removal of the vadvise syscall requires manual removal of all
199 associated files from the libc build object directory (including
200 the .depend files) - a command like:
201 cd $OBJ && find . -type d -name libc | xargs rm -rf
202 For architectures that support multiple "compat" binary targets,
203 you'll need to cleanup both the regular libc directory and the
204 compat ones (the above command will do that).
205
206 20171010:
207 a change to the build structure of external/bsd/acpica/bin/iasl
208 means that its objdir (or *.d and .depend at least) might need
209 to be manually removed - or a build done once without -u.
210
211 20170822:
212 a new version of GMP has been imported and probably
213 will break parts of builds related to themselves or GCC, both
214 in the tools and the native section. Remove all GCC, GMP, MPFR
215 and MPC objdirs or build once without -u.
216
217 20170816:
218 a new version of MPFR and MPC have been imported and probably
219 will break parts of builds related to themselves or GCC, both
220 in the tools and the native section. Remove all GCC, GMP, MPFR
221 and MPC objdirs or build once without -u.
222
223 20170402:
224 a new version of dhcpcd has been imported, which does not support
225 update builds from the previous version. Remove your
226 external/bsd/dhcpcd object dir or build once without -u.
227
228 20170211:
229 a new terminfo database has been imported.
230 The structure of it has changed slightly from prior versions and
231 an updated tic tool is required.
232 If you build.sh, don't use -u
233
234 20170207:
235 various arch dependent libc/exect.S files were removed
236 Either remove the obj directories (lib/libc and compat/amd64/i386/lib
237 if it exists) or do a clean build.
238 (This is a bug in the make system, it should be corrected without
239 human intervention, but isn't.)
240
241 20170104:
242 xinput build options have changed.
243 Remove the obj directory (external/mit/xorg/bin/xinput)
244 if you build.sh -u
245
246 20170103:
247 a new version of flex has been imported.
248 Remove the file from obj (external/bsd/flex)
249 if you build.sh -u
250
251 20161014:
252 a new version of OpenSSL has been imported.
253 Remove the files from obj (crypto/external/bsd/openssl)
254 if you build.sh -u
255
256 20161009:
257 a new version of dhcpcd has been imported with slightly changed
258 build infrastructure. When doing a build.sh -u this requires
259 pruning the external/bsd/dhcpcd objdir.
260
261 20160914:
262 i386, amd64, shark, ofppc and macppc have joined shark and x68k
263 ports in using xorg-server 1.18. This requires a clean destdir
264 and a clean objdir.
265
266 20160527:
267 i386 needs a full cleandir or objdir deletion because PIE has
268 been enabled. (see the amd64 entry two down for further info)
269
270 20160418:
271 libedit needs manual removal of all autogenerated files since
272 some of them are not autogenerated anymore. Remember that there
273 might be two copies of libedit if your platform builds "compat".
274
275 20160410:
276 amd64 needs full "make cleandir" or deletion of objdir now that
277 PIE has been enabled for amd64. PIE, or position-independent
278 executables, means all code, including executables and not just
279 shared libraries, is position-independent and hence able to be
280 relocated by ASLR, address space layout randomization.
281
282 The change was made in Makefile variables for compiler and
283 linker flags, for which make(1) does not record dependencies,
284 hence it is unable to detect that all .o files need rebuilding.
285
286 Partial rebuilds with some modified source files will likely
287 fail when linking executables, since the linker refuses to mix
288 position-independent code with position-dependent code in
289 position-independent executables:
290
291 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
292
293 20160401:
294 Ports switching to GCC 5.3 will need a full "make cleandir".
295 Some people have found that cleandir is not sufficient, so if
296 in doubt delete the entire object directory tree for gcc.
297
298 20160306:
299 NetBSD's regexp implementation is now part of libnbcompat.
300 Nblex, nbm4, nbpax, nbsed use it and they may crash on
301 non-NetBSD hosts if linked with stale object files produced
302 while they included a non-NetBSD regex.h.
303 In any case, you should "make cleandir" at least these tools
304 before updating your toolchain.
305
306 20160125:
307 Dtrace has been enabled by default on some architectures.
308 When doing an update build, make sure to clean the etc/mtree
309 object directory before starting the build - otherwise the
310 needed directories in destdir will not be created.
311 An easy way to do this is:
312 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
313
314 20150818:
315 New acpica requires "make cleandir" in src/external/bsd/acpica
316 again.
317
318 20150413:
319 New acpica requires "make cleandir" and reinstalling yacc
320 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
321 also "make cleandir" in /usr/src/external/bsd/acpica.
322
323 20150404:
324 Lint changes require a full rebuild of the tool, so make
325 sure to build without -u option to build.sh, or manually
326 do a make cleandir in src/tools/lint1 and
327 src/usr.bin/xlint.
328
329 20150310:
330 Improvements to openssl for arm mean that update builds of
331 the openssl libraries will fail. A make cleandir in
332 external/bsd/openssl/lib is needed
333
334 20141026:
335 A mishap during the import of pppd may cause your corruption
336 in your cvs directory if you happened to do a cvs update
337 during a short period of time. To fix, just remove the
338 directory src/external/bsd/ppp/dist/pppd completely
339 and let cvs restore it on next update.
340
341 20140721:
342 The src/external/mit/lua/src directory was accidentally created
343 and then deleted in the CVS repository. If you get errors like
344
345 cvs [update aborted]: cannot open directory
346 /cvsroot/src/external/mit/lua/src: No such file or directory
347
348 then delete your local copy of that directory tree and try again.
349
350 20140530:
351 ARM eABI switched to DWARF based exception handling. This requires
352 rebuilding all C++ code. It is strongly advised to do a clean build.
353
354 20140131:
355 The new compiler_rt/libc integration moved a few things. It is strongly
356 advised to do a clean build. At least lib/libc, the compat version(s)
357 of libc, libkern, rump and the kernels need to be cleaned.
358
359 20131227:
360 1. The new ntpd runs in a restricted mode to prevent amplification
361 attacks. If you need ntpdc to work you need to explicitly enable
362 mode7 in your config file. Make sure you put the necessary restrict
363 statements to avoid being exposed.
364 2. strncat has moved from lib/libc to common/lib/libc; you might need
365 to make clean in libc
366
367 20131129:
368 The GMP sources were updated, and builds will likely fail without
369 cleaning their build trees for both tools and in-tree, like below.
370
371 20131128:
372 The MPC and MPFR sources were updated, and builds may require their
373 tools and in-tree directories cleaned for successful updates.
374
375 20130605:
376 The kernel option FAST_IPSEC no longer exists, it's been renamed
377 to IPSEC (and the older IPSEC version removed).
378
379 20130605:
380 Previous freetype installations eroneously installed private
381 header files. If you are building against a non-empty $DESTDIR,
382 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
383
384 20130531:
385 The xdm update may cause build failure due to xdm.man being
386 in the obj tree. Make sure to ensure any like this:
387 nbmake: nbmake: don't know how to make xdm.man. Stop
388 is fixed by deleting the xdm.man in the obj tree.
389
390 20130530:
391 Updates of many xsrc packages will leave old .pc files around.
392 Best to clean out the xsrc objdir entirely before rebuilds.
393
394 20130301:
395 The removal of netiso requires manual removal of /usr/include/netiso
396 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
397
398 20120726:
399 The update of OpenSSL requires cleaning both the OpenSSL build
400 directory and DESTDIR. *Even non-update builds require cleaning
401 DESTDIR.* Builds done without taking these steps may fail, or in
402 some cases may succeed and install broken OpenSSL libraries that
403 cause third-party software to link incorrectly and/or crash.
404
405 20120507:
406 The database schema for makemandb was changed. You will
407 need to update the database using 'makemandb -f' or wait
408 for the next weekly run to fix it.
409
410 20120319:
411 sys/conf/Makefile.kern.inc has been modified to adjust the
412 size of db_symtab automatically. You need to update dbsym in
413 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
414 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
415 mk.conf.
416
417 20120216:
418 Default for MKCATPAGES changed to NO. Update builds will fail
419 unless DESTDIR is cleaned manually. If you built between 20120207
420 and 20120216, daily and weekly could have created an unreadable
421 /var/db/man.db index for apropos. Running makemandb -f or
422 the next run of weekly will fix it.
423
424 20111227:
425 If you built between 20111225 and 20111227 you need to remove
426 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
427 bump has been reverted.
428
429 20111125:
430 The "rnd" pseudodevice has been added to sys/conf/std, which
431 means it should no longer be explicitly listed in kernel
432 configuration files. The line "pseudo-device rnd" should be
433 removed from any custom kernel config files users may have.
434
435 20111119:
436 A problem with the datastructures used by the rndctl(8)
437 utility (pointers in datastructures in an array, making 32->64
438 bit compatibility very painful) has been fixed in a
439 non-backwards-compatible way. If you replace your kernel,
440 replace your rndctl executable too.
441
442 20111001:
443 the prop_*_send_syscall() functions from proplib(3) have been
444 changed and their new version is not backward compatible with the old
445 one. So ensure that all consumers of these functions (currently:
446 quota2 code and its tests) are updated together with the new lib.
447
448 20110817:
449 sparc has been changed to use GCC 4.5.3, so any objdir or
450 DESTDIR for them should be deleted before updating.
451
452 20110806:
453 i386 and amd64 have been changed to use GCC 4.5.3, so any
454 objdir or DESTDIR for them should be deleted before updating.
455
456 20110805:
457 The update to GCC 4.5.3 requires a non-trivial portion of
458 the tree to be cleaned. Best to delete both objdir and
459 DESTDIR before running this update. So far, only the
460 sparc64, mips and powerpc platforms have changed.
461
462 20110803:
463 The layout of external/public-domain/xz has changed. To do an
464 update build you will have to remove the contents of the OBJDIR
465 for external/public-domain/xz/bin by hand as the xz entry there
466 is now a directory.
467
468 20110410:
469 The configuration of src/tools/gcc has changed. To do an
470 update build you have to clean both tools/binutils and
471 tools/gcc by hand.
472
473 20110328:
474 Building the Xorg binary was moved into a subdirectory to fix
475 ordering issues with "make all". It may be necessary to remove
476 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
477 if your update build fails, as the "Xorg" entry there is now a
478 directory.
479
480 20110121:
481 Assembler files no longer use -traditional-cpp. This can break
482 the build of individual parts of the tree. This is handled
483 correctly by build.sh. Manual builds have to update /usr/share/mk
484 and re-run config(1) for any kernel configurations as needed.
485
486 20101217:
487 The tcpdump(8) program was changed to drop privileges and chroot(2)
488 by default. It may be necessary to manually update passwd(5) and
489 group(5) in order to make the program work with existing setups.
490
491 20101125:
492 The latest changes to setenv(3) dissallow setting environment
493 variables with names that contain '='. Revision 1.18 of env.c
494 assumed that this was allowed. Installing a new libc with an
495 old copy of /usr/bin/env causes env x=1 printenv | grep x= to
496 break which affects the autoconf tests for dependency finding,
497 so building gcc will end up printing:
498 checking dependency style of gcc... none
499 configure: error: no usable dependency style found
500 Fix it by rebuilding and re-installing env.
501
502 20101119:
503 Recent Xorg updates in xsrc/external/mit/ may cause various build
504 or run-time problems. Delete your entire DESTDIR and OBJDIR if you
505 have any build problems with xsrc, or problems with mismatched
506 versions between xorg-server and drivers.
507
508 20100604:
509 The update of ATF to 0.9 causes old tests written in shell to fail
510 unless they are rebuilt. If you are building with MKUPDATE=yes,
511 you need to clean the src/external/bsd/atf/tests/ and the src/tests/
512 trees by hand.
513
514 20100522:
515 Recent Xorg updates in xsrc/external/mit/ will cause various build
516 problems. Delete your entire DESTDIR and OBJDIR if you have any
517 build problems with xsrc.
518
519 20100522:
520 private section of <ctype.h> was splitted, and now mklocale(1)
521 include ctype_local.h, so you have to make cleandir in tools/mklocale.
522
523 20100520:
524 The location of the xkb compiled descriptions has changed. Please
525 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
526
527 20100222:
528 The shared objects file extension has been changed from .so to
529 .pico, in order to avoid conflicts with shared libraries names
530 libXX.so. All now stale regular .so files can be removed from
531 your object directories.
532
533 20100204:
534 The termcap database has been removed from the sources,
535 but has not been marked obsolete so it is not removed
536 from the system when upgrading.
537 As such, you will need to remove them from your object
538 and destination directories.
539
540 20091101:
541 After updating, it may be necessary to make the 'cleandir'
542 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
543 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
544 src/tools/lex/ and src/usr.bin/lex/.
545
546 20091001:
547 On amd64 you must rebuild tools (to get the new binutils)
548 before building a kernel, or the build fails on cpufunc.S.
549
550 20091001:
551 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
552 symlink, failing the build. Delete the link, and the subdir
553 it is in, and retry your build.
554
555 20090718:
556 libc build changed so that strchr() provides the extra entry
557 point for index(). Update build of libc.a (and libc_pic.a)
558 may fail because the archive contains the unwanted index.o.
559 (Similarly for strrchr() and rindex().)
560
561 20090709:
562 Native Xorg was upgraded again. Builds will probably fail again
563 without a clean objdir, at least for src/external/mit/xorg.
564
565 20090616:
566 Native Xorg was upgraded. Builds will need a clean objdir for
567 src/external/mit/xorg. Upgrading a system from sets will not
568 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
569 subdirectory has been changed into a file, and this needs to
570 be manually "rm -r"'ed before installing xbase.tgz.
571
572 20090501:
573 Several new functions were added to string.h/libc, and this
574 can cause autoconf problems during the tool build for people
575 who fail to clean out their tools objects properly. If you
576 note messages about stpcpy, stpncpy or strnlen accompanying a
577 failure during the tool build, clean out all your tools
578 objects and start again.
579
580 20090325:
581 The i386 port was switched to i486 default toolchain. This requires
582 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
583
584 20090126:
585 The __posix_fadvise50 system call changed assembly stub type. You
586 need to 'rm -f __posix_fadvise50.*' in the libc build directory
587 to avoid using the old assembly stub.
588
589 20090202:
590 pkg_install now depends on the pkgdb cache for automatic conflict
591 detection. It is recommented to rebuild the cache with
592 ``pkg_admin rebuild''.
593
594 20090110:
595 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
596 1. Make sure your kernel has COMPAT_50 in it. Build and install.
597 This is needed even in the MODULAR kernel because there is
598 conditionally compiled code in rtsock.c.
599 2. make sure build.sh completes and the binaries in a chroot work
600 before installing.
601 3. If you don't use build.sh and you build directly to root, and
602 your build breaks in the middle, don't despair. Make sure headers
603 are installed properly, and start building libraries first libc
604 and libutil, install them and then continue building all the
605 libraries in src/lib and src/gnu/lib and install them. Once
606 the new libraries are installed, you can restart the build.
607 4. If you compile packages and you notice link time warnings,
608 rebuild the required packages to update their shared libraries.
609 Any package you rebuild will require rebuilding all the packages
610 that depend on it.
611 5. Next time you run pwd_mkdb with the new binary, the file
612 will be upgraded and it will not be backwards compatible.
613 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
614 lastlogx(5)) have been versioned, and there is a heuristic
615 for utmp. You are better off removing the old files after
616 upgrading. The automated clearing of /var/run during
617 boot, and the automated rotating of files in /var/log by
618 newsyslog(8), may mean that you do not have to remove the
619 files manually.
620 7. The optional accounting file (/var/account/acct, see
621 accton(8)) has not been versioned, and will need to be
622 removed. The automatic rotation of the accounting file by
623 /etc/daily limits the bad consequences of failure to remove
624 the file.
625 8. Application software that writes time_t to binary files on
626 disk will break or need attention. Most notably: if you are
627 using PostgreSQL < 8.4, you need to dump your databases,
628 rebuild PostgreSQL with the new time_t, then restore.
629
630 20081219:
631 config(1) has been updated, and one of the files it creates -
632 swapnetbsd.o - has changed format. You need to rebuild config
633 (done automatically by build.sh) and then you need to rerun
634 config on all kernel configuration files before rebuilding those
635 kernels.
636
637 20081205:
638 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
639 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
640 set and will appear as extra files for MKX11=no update builds.
641
642 20081122:
643 On i386, various kernel options(4) in GENERIC including
644 file systems have been disabled and moved into kernel modules.
645 Before trying a new GENERIC kernel, you have to prepare the
646 following files as well as a new GENERIC kernel:
647
648 - build and install kernel modules from src/sys/modules
649
650 - install the latest bootloader, which will load a module
651 for the file system from which the kernel is loaded automatically
652
653 If you have to load your kernel from a file system which is not of
654 the same type as the root file system, you have to load the necessary
655 file system module manually on the boot prompt or in the boot.cfg file.
656
657 20080827:
658 If you built and installed a libc from sources between
659 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
660 which results in false errors reported by lint(1).
661 Since this breaks the libc build itself, manual help is
662 needed -- lint must be disabled temporarily, e.g.:
663 $ (cd lib/libc && make MKLINT=no dependall install)
664
665 20080813:
666 MKDEBUG build was broken because the .depend files did not know
667 about .go files. You need to remove all .depend files and rebuild.
668
669 20080802:
670 A regression in binary compatibility for pthread_mutex_t has
671 been fixed. Unfortunately, the price is breaking compatibility
672 for -current.
673
674 Threaded programs (using libpthread) and C++ programs (using
675 libstdc++) compiled after 20070907 and before 20080802 need to
676 be recompiled.
677
678 One way to find affected pkgsrc packages:
679
680 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
681 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
682
683 20080731:
684 WAPBL (metadata journaling support) has been added, but at this
685 time isn't backwards compatible with pre-WAPBL aware kernels
686 and userland (fsck_ffs in particular). Please make sure you
687 don't use a journaled filesystem with an older kernel/userland,
688 especially an uncleanly mounted journaled filesystem. WAPBL
689 also requires the super block to be in the UFS2 format. You
690 can use fsck_ffs -c 4 to update the superblock format.
691
692 20080721:
693 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
694 isn't defined.
695
696 20080531:
697 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
698 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
699 utility needs to be rebuilt and reinstalled as older binaries
700 won't work correctly. The following sequence of commands:
701
702 $ (cd sys/sys/ && nbmake-$arch includes)
703 $ (cd sbin/drvctl/ && nbmake-$arch clean)
704 $ (cd sbin/drvctl/ && nbmake-$arch all)
705
706 leaves new drvctl utility in sbin/drvctl build directory.
707
708 20080503:
709 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
710
711 20080521:
712 For a while, unprivileged UPDATE builds would fail to
713 succeed at the checkflist stage, complaining that
714 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
715 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
716 If you already hit this problem, update the .mk file,
717 remove ${DESTDIR}/stand/<arch>, and re-run the build.
718
719 20080303:
720 Linker warnings are now fatal if $WARNS>0.
721
722 20080126:
723 The posix_fadvise system call has been changed from an assembly
724 stub, to a c file that calls an assembly stub. You need to
725 'rm -f posix_fadvise.* .depend' in the libc build directory to
726 avoid using the old assembly stub.
727
728 20071209:
729 The acpiec(4) driver has been split into two attachments. If you
730 get ACPI errors before the attachment, please update your kernel
731 configuration file appropriately or see GENERIC for more details.
732
733 20071115:
734 The it(4) driver has been renamed to itesio(4) and the old port
735 argument specified in the kernel configuration file is not valid
736 anymore. The itesio(4) driver now uses the Super I/O address port
737 rather than the EC address port. Please update your kernel
738 configuration file appropriately or see GENERIC for more details.
739
740 20071028:
741 The pccons(4) driver has been removed from the NetBSD/shark port.
742 You need to update any custom kernel configuration file you have
743 to remove any references to pccons (which includes removing the
744 now useless XSERVER option) and replace them with the correct
745 entries for the wscons driver. See the GENERIC configuration file
746 for more details.
747
748 20070913:
749 A latent bug in dhclient/dhcpd that caused it to be unable to
750 enumerate interfaces was fixed. The bug began to cause
751 problems after 20070911 when the kernel's SIOCGIFCONF
752 implementation was repaired. From 20070529 to 20070911 racoon
753 could not enumerate interfaces. (These are noted because
754 normal kernel/userspace version matching hygiene is not
755 sufficient to avoid this problem.) Ensure that both kernel
756 and userland are from after 20070913.
757
758 20070703:
759 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
760 calls the target-specific strip program, and the logic to pass
761 down STRIP from make has been removed. This requires a
762 re-installation of tools.
763
764 20070422:
765 The way OS emulations lookup filenames inside the emulation root
766 has been changed. Rather than modify the pathname (and copy back
767 to userspace) namei() and lookup() directly check the emulation
768 root. One side effect is that absolute symlinks inside the emulated
769 root file system will be relative to that file system - unless they
770 start /../ this is useful when the emulated root is a real install
771 that has such links.
772 This might affect symlinks that have been added to reference outside
773 the emulated root.
774
775 20070412:
776 The pckbc driver on sgimips IP32 has been removed. Use macekbc
777 instead. See the GENERIC32_IP3x kernel configuration for an
778 example.
779
780 20070319:
781 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
782 on many platforms due to incorrect flags settings. If you
783 updated and built after about 20070315, do "nbmake-$arch
784 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
785 rebuild of object files that might have been built
786 incorrectly, and ensure that you have at least
787 src/lib/libc/Makefile 1.130.
788
789 20070210:
790 src/sys/sys/{sa.h,savar.h} were removed.
791 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
792 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
793 will allow dependencies on those files to get get rebuilt
794
795 20070209:
796 The threading model was changed when the newlock2 branch
797 was merged to NetBSD-current. If you boot with a new
798 kernel (version 4.99.10), then you also need a new pthread
799 library (/usr/lib/libpthread.so.0.7). If you boot with
800 an old kernel, then you need the old pthread library
801 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
802 the pthread library in sync, old threaded applications should
803 continue to work with an old or new kernel. Note that named(8)
804 is the only threaded application in the base system.
805
806 20061214:
807 Following the move of string_to_flags() and flags_to_string()
808 from the bin/ls/ sources to libutil, users doing UPDATE builds
809 will need to do a "make cleandir" in
810 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
811 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
812 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
813 as the installation images in distrib/
814 in order to excise stale references to the old stat_flags.h header
815 file in the ls sources -- stat_flags.h has been removed.
816
817 20061108:
818 The configure script used in the src/tools/gcc compiler has been
819 changed to indicate that our libc has ssp support built-in and
820 does not depend on -lssp and -lssp-nonshared. You'll need to
821 make clean in src/tools/gcc first to rebuild the compiler.
822
823 20061009:
824 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
825 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
826
827 20060814:
828 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
829 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
830 kernel configuration for an example. X servers from the last
831 few years should cope.
832
833 20060703:
834 MPACPI is no more. We always configure PCI interrupts using ACPI
835 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
836 to ACPI_SCANPCI. Thanks to work from fvdl.
837
838 20060627:
839 socket(2) has changed, and its system call has been versioned.
840 For userlands with the old version of socket(2), make sure that
841 your kernel has 'options COMPAT_30' set, or else 'bad system call'
842 errors will result.
843
844 Hints for a more successful build:
845 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
846 Use build.sh, but do not use its "expert mode":
847 This will automatically build the tools in the
848 correct order, and it will keep the tools and the
849 new build products from interfering with the running
850 system. This will allow you to ignore most of the
851 other advice in this file.
852 Build a new kernel first:
853 This makes sure that any new system calls or features
854 expected by the new userland will be present. This
855 helps to avoid critical errors when upgrading.
856 Use object directories:
857 This helps to keep stale object
858 files from polluting the build if a Makefile "forgets"
859 about one. It also makes it easier to clean up after
860 a build. It's also necessary if you want to use the
861 same source tree for multiple machines.
862 To use object directories with build.sh:
863 a) invoke build.sh with the "-M" or "-O" options.
864 To use object directories without using build.sh:
865 a) cd /usr/src ; make cleandir
866 b) Add "OBJMACHINE=yes" to /etc/mk.conf
867 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
868 d) cd /usr/src ; make build
869 Note that running "make obj" in a directory will create
870 in obj.$MACHINE directory.
871 Build to a DESTDIR:
872 This helps to keep old installed files (especially libraries)
873 from interfering with the new build.
874 To build to a DESTDIR with build.sh, use the "-D" option.
875 To build to a DESTDIR without using build.sh, set the DESTDIR
876 environment variable before running make build. It should be
877 set to the pathname of an initially empty directory.
878 Problems: if you do not use build.sh, you might need to
879 update critical utilities without using DESTDIR since
880 nothing is executed from what is installed in DESTDIR.
881 (See critical utils, below.)
882 Build often:
883 This keeps critical utilities current enough to not choke
884 on any other part of the source tree that depends on up to
885 date functionality. If you use build.sh, you should not have
886 this problem.
887
888 What to do if things don't work:
889 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
890 When things don't work there are usually a few things that commonly
891 should be done.
892 1) make includes
893 This should be done automatically by make build.
894 2) cd share/mk && make install
895 Again, automatically done by make build.
896
897 Failsafe rebuild of a small part of the tree:
898 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
899 To make sure you rebuild something correctly you want to do
900 something like the following:
901 1) Make sure the includes and .mk files are up to date.
902 2) Make sure any program used to build the particular
903 utility is up to date. (yacc, lex, etc...)
904 3) cd ...path/to/util...
905 make cleandir
906 rm ...all obj directories...
907 make cleandir # yes, again
908 make obj
909 make depend && make
910
911 Failsafe rebuild of the entire tree:
912 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
913 If you really want to make sure the source tree is clean and
914 ready for a build try the following. Note that sourcing /etc/mk.conf
915 (a make(1) Makefile) in this manner is not right, and will not work
916 for anyone who uses any make(1) features in /etc/mk.conf.
917

951 Other problems and possible solutions:
952 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
953 Symptom:Complaints involving a Makefile.
954 Fix: Rebuild usr.bin/make:
955 cd usr.bin/make && make && make install
956 Or, a failsafe method if that doesn't work:
957 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
958
959 Fix: Make sure .mk files are up to date.
960 cd share/mk && make install
961
962 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
963 Fix: Rebuild usr.bin/config
964
965 Symptom:
966 Fix: Rebuild usr.bin/yacc
967
968 Symptom:
969 Fix: Rebuild usr.bin/lex
970
971 Symptom:
972 Fix: rm /usr/lib/libbfd.a
973
974 Symptom:Obsolete intermediate files are used during compilation
975 Fix: Try the following sequence of commands in the directory in question.
976 make cleandir; rm `make print-objdir`; make cleandir; make obj
977 (If you built the tree without "make obj" in the past, obsolete files
978 may remain. The command tries to clean everything up)

999 Symptom:Update build fails in src/tools/gcc complaining that a variable
1000 (e.g. CPPFLAGS) has changed since the previous run.
1001 Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
1002
1003 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
1004 No such file or directory.
1005 Cause: If a directory is created by mistake, then it is sometimes
1006 deleted from the CVS repository using administrative commands
1007 that bypass the normal cvs access controls. If your cvs working tree
1008 contains references to a directory that has been deleted on the
1009 server in this way, then "cvs update" reports this error.
1010 Fix: Recursively delete the affected directory from your working tree
1011 and try the update again.
