UPDATING revision 1.315 1 $NetBSD: UPDATING,v 1.315 2020/09/26 08:02:35 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 20200925:
23 GNU MPC and MPFR have been updated. At least MPFR needs cleaning
24 in both the tools and external dirs.
25
26 20200912:
27 GCC 9 has arrived for Arm and x86 platforms, and will be coming
28 for several more, as will binutils 2.34. Clean as required.
29
30 20200907:
31 GCC 9 is coming, and binutils has been updated for MIPS. This
32 probably requires cleaning the tools/binutils.
33
34 20200811:
35 GCC updates may require cleaning the objdir. This may occur
36 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming
37 GCC 9 upgrade.
38
39 20200614:
40 blacklist* has been renamed to blocklist*. postinstall(8)
41 should handle the migration
42
43 20200601:
44 Due to a mistake in LIBISPRIVATE handling, .so libraries were
45 created in the build directories and need cleaning.
46
47 20200311:
48 GCC 8 ports will need cleaning in src/tools/gcc and
49 src/external/gpl3/gcc due to GCC 8.4 update.
50
51 20191118:
52 More architectures were switched to gcc8:
53 i386, ia64 powerpc64, sparc, sparc64, arm
54 The same comments as in 20191022 apply.
55
56 20191112:
57 The LLVM update requires a clean rebuild for all architectures using
58 LLVM during the tools build phase (i386, amd64, aarch64).
59
60 20191022:
61 Ports amd64 and aarch64 switched to GCC 8.3 by default.
62 In-place ("expert mode", build.sh -E) builds are not supported
63 when going from a GCC 7 userland to GCC 8. Do a regular
64 build to a different DESTDIR (or preferably: build.sh -U) at least
65 once and install sets, or download comp.{tar.xz,tgz} from the
66 daily builds and install that before doing the next in-place build.
67
68 20191001:
69 GCC 8.3 was imported. Builds of src/tools/gcc may fail if
70 old builds with GCC 7 output now uses GCC 8. Clean this
71 directory, and also clean src/external/gpl3/gcc.
72
73 20190903:
74 Files with names that coincide with existing files' names on
75 case-insensitive file systems were inadvertently committed, for
76 radeon GPU firmware. We cannot mark these as obsolete for
77 postinstall to fix, so if you updated src since 2019-08-26, and
78 ran build.sh distribution or ran build.sh release, you must
79 manually delete the following files in your DESTDIR (which is
80 usually $OBJDIR/destir.$ARCH), or from / if you have installed
81 them:

150 We will re-import these radeon firmware images another way
151 later.
152
153 20190727:
154 The uefi bootloader has gained tftp support and needs a clean
155 build. If you do update builds, manually clean its object
156 directory by something like:
157 cd sys/arch/i386/stand/efiboot && make clean
158
159 20190723:
160 The jemalloc allocator in libc is now build without extended
161 debugging (for performance reasons). In update builds make sure
162 to rebuild it completly, by removing all affected object files,
163 including compat builds, something like:
164 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
165
166 20190207:
167 GCC 7 switched for many ports. Update builds are likely to fail.
168
169 20180924:
170 A newer OpenSSL version has been imported. If you are doing
171 update builds, make sure to remove all old obj dirs, like:
172 cd /usr/obj && find . -type d -name openssl | xargs rm -rf
173
174 20180717:
175 On aarch64 int64_t and related types have changed from long long
176 to long. This requires recompiling all C++ binaries.
177
178 20180713:
179 On amd64 and i386 static binaries are now build position
180 independend. This requires recompilation of all object
181 files used to create the crunched /rescue binary.
182 Clean the rescue directory in your obj directory before
183 doing an update build, otherwise linking will fail.
184
185 20180414:
186 Existing binutils was migrated to binutils.old. Manual
187 removal of tools/binutils objects directory may be required
188 to fix tools build failure.
189
190 20180311:
191 bdftopcf was updated and may need cleaning in the
192 src/external/mit/xorg/tools/bdftopcf subdirectory if there are
193 link errors.
194
195 20180212:
196 between OpenSSL and GCC updates, many things may fail to build.
197 any failure that looks like GCC or openssl is best handled by
198 a clean destdir and objdir. Full cleandir and destdir deletion
199 is recommended if build failures occur.
200
201 20171225:
202 removal of the vadvise syscall requires manual removal of all
203 associated files from the libc build object directory (including
204 the .depend files) - a command like:
205 cd $OBJ && find . -type d -name libc | xargs rm -rf
206 For architectures that support multiple "compat" binary targets,
207 you'll need to cleanup both the regular libc directory and the
208 compat ones (the above command will do that).
209
210 20171010:
211 a change to the build structure of external/bsd/acpica/bin/iasl
212 means that its objdir (or *.d and .depend at least) might need
213 to be manually removed - or a build done once without -u.
214
215 20170822:
216 a new version of GMP has been imported and probably
217 will break parts of builds related to themselves or GCC, both
218 in the tools and the native section. Remove all GCC, GMP, MPFR
219 and MPC objdirs or build once without -u.
220
221 20170816:
222 a new version of MPFR and MPC have been imported and probably
223 will break parts of builds related to themselves or GCC, both
224 in the tools and the native section. Remove all GCC, GMP, MPFR
225 and MPC objdirs or build once without -u.
226
227 20170402:
228 a new version of dhcpcd has been imported, which does not support
229 update builds from the previous version. Remove your
230 external/bsd/dhcpcd object dir or build once without -u.
231
232 20170211:
233 a new terminfo database has been imported.
234 The structure of it has changed slightly from prior versions and
235 an updated tic tool is required.
236 If you build.sh, don't use -u
237
238 20170207:
239 various arch dependent libc/exect.S files were removed
240 Either remove the obj directories (lib/libc and compat/amd64/i386/lib
241 if it exists) or do a clean build.
242 (This is a bug in the make system, it should be corrected without
243 human intervention, but isn't.)
244
245 20170104:
246 xinput build options have changed.
247 Remove the obj directory (external/mit/xorg/bin/xinput)
248 if you build.sh -u
249
250 20170103:
251 a new version of flex has been imported.
252 Remove the file from obj (external/bsd/flex)
253 if you build.sh -u
254
255 20161014:
256 a new version of OpenSSL has been imported.
257 Remove the files from obj (crypto/external/bsd/openssl)
258 if you build.sh -u
259
260 20161009:
261 a new version of dhcpcd has been imported with slightly changed
262 build infrastructure. When doing a build.sh -u this requires
263 pruning the external/bsd/dhcpcd objdir.
264
265 20160914:
266 i386, amd64, shark, ofppc and macppc have joined shark and x68k
267 ports in using xorg-server 1.18. This requires a clean destdir
268 and a clean objdir.
269
270 20160527:
271 i386 needs a full cleandir or objdir deletion because PIE has
272 been enabled. (see the amd64 entry two down for further info)
273
274 20160418:
275 libedit needs manual removal of all autogenerated files since
276 some of them are not autogenerated anymore. Remember that there
277 might be two copies of libedit if your platform builds "compat".
278
279 20160410:
280 amd64 needs full "make cleandir" or deletion of objdir now that
281 PIE has been enabled for amd64. PIE, or position-independent
282 executables, means all code, including executables and not just
283 shared libraries, is position-independent and hence able to be
284 relocated by ASLR, address space layout randomization.
285
286 The change was made in Makefile variables for compiler and
287 linker flags, for which make(1) does not record dependencies,
288 hence it is unable to detect that all .o files need rebuilding.
289
290 Partial rebuilds with some modified source files will likely
291 fail when linking executables, since the linker refuses to mix
292 position-independent code with position-dependent code in
293 position-independent executables:
294
295 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
296
297 20160401:
298 Ports switching to GCC 5.3 will need a full "make cleandir".
299 Some people have found that cleandir is not sufficient, so if
300 in doubt delete the entire object directory tree for gcc.
301
302 20160306:
303 NetBSD's regexp implementation is now part of libnbcompat.
304 Nblex, nbm4, nbpax, nbsed use it and they may crash on
305 non-NetBSD hosts if linked with stale object files produced
306 while they included a non-NetBSD regex.h.
307 In any case, you should "make cleandir" at least these tools
308 before updating your toolchain.
309
310 20160125:
311 Dtrace has been enabled by default on some architectures.
312 When doing an update build, make sure to clean the etc/mtree
313 object directory before starting the build - otherwise the
314 needed directories in destdir will not be created.
315 An easy way to do this is:
316 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
317
318 20150818:
319 New acpica requires "make cleandir" in src/external/bsd/acpica
320 again.
321
322 20150413:
323 New acpica requires "make cleandir" and reinstalling yacc
324 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
325 also "make cleandir" in /usr/src/external/bsd/acpica.
326
327 20150404:
328 Lint changes require a full rebuild of the tool, so make
329 sure to build without -u option to build.sh, or manually
330 do a make cleandir in src/tools/lint1 and
331 src/usr.bin/xlint.
332
333 20150310:
334 Improvements to openssl for arm mean that update builds of
335 the openssl libraries will fail. A make cleandir in
336 external/bsd/openssl/lib is needed
337
338 20141026:
339 A mishap during the import of pppd may cause your corruption
340 in your cvs directory if you happened to do a cvs update
341 during a short period of time. To fix, just remove the
342 directory src/external/bsd/ppp/dist/pppd completely
343 and let cvs restore it on next update.
344
345 20140721:
346 The src/external/mit/lua/src directory was accidentally created
347 and then deleted in the CVS repository. If you get errors like
348
349 cvs [update aborted]: cannot open directory
350 /cvsroot/src/external/mit/lua/src: No such file or directory
351
352 then delete your local copy of that directory tree and try again.
353
354 20140530:
355 ARM eABI switched to DWARF based exception handling. This requires
356 rebuilding all C++ code. It is strongly advised to do a clean build.
357
358 20140131:
359 The new compiler_rt/libc integration moved a few things. It is strongly
360 advised to do a clean build. At least lib/libc, the compat version(s)
361 of libc, libkern, rump and the kernels need to be cleaned.
362
363 20131227:
364 1. The new ntpd runs in a restricted mode to prevent amplification
365 attacks. If you need ntpdc to work you need to explicitly enable
366 mode7 in your config file. Make sure you put the necessary restrict
367 statements to avoid being exposed.
368 2. strncat has moved from lib/libc to common/lib/libc; you might need
369 to make clean in libc
370
371 20131129:
372 The GMP sources were updated, and builds will likely fail without
373 cleaning their build trees for both tools and in-tree, like below.
374
375 20131128:
376 The MPC and MPFR sources were updated, and builds may require their
377 tools and in-tree directories cleaned for successful updates.
378
379 20130605:
380 The kernel option FAST_IPSEC no longer exists, it's been renamed
381 to IPSEC (and the older IPSEC version removed).
382
383 20130605:
384 Previous freetype installations eroneously installed private
385 header files. If you are building against a non-empty $DESTDIR,
386 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
387
388 20130531:
389 The xdm update may cause build failure due to xdm.man being
390 in the obj tree. Make sure to ensure any like this:
391 nbmake: nbmake: don't know how to make xdm.man. Stop
392 is fixed by deleting the xdm.man in the obj tree.
393
394 20130530:
395 Updates of many xsrc packages will leave old .pc files around.
396 Best to clean out the xsrc objdir entirely before rebuilds.
397
398 20130301:
399 The removal of netiso requires manual removal of /usr/include/netiso
400 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
401
402 20120726:
403 The update of OpenSSL requires cleaning both the OpenSSL build
404 directory and DESTDIR. *Even non-update builds require cleaning
405 DESTDIR.* Builds done without taking these steps may fail, or in
406 some cases may succeed and install broken OpenSSL libraries that
407 cause third-party software to link incorrectly and/or crash.
408
409 20120507:
410 The database schema for makemandb was changed. You will
411 need to update the database using 'makemandb -f' or wait
412 for the next weekly run to fix it.
413
414 20120319:
415 sys/conf/Makefile.kern.inc has been modified to adjust the
416 size of db_symtab automatically. You need to update dbsym in
417 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
418 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
419 mk.conf.
420
421 20120216:
422 Default for MKCATPAGES changed to NO. Update builds will fail
423 unless DESTDIR is cleaned manually. If you built between 20120207
424 and 20120216, daily and weekly could have created an unreadable
425 /var/db/man.db index for apropos. Running makemandb -f or
426 the next run of weekly will fix it.
427
428 20111227:
429 If you built between 20111225 and 20111227 you need to remove
430 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
431 bump has been reverted.
432
433 20111125:
434 The "rnd" pseudodevice has been added to sys/conf/std, which
435 means it should no longer be explicitly listed in kernel
436 configuration files. The line "pseudo-device rnd" should be
437 removed from any custom kernel config files users may have.
438
439 20111119:
440 A problem with the datastructures used by the rndctl(8)
441 utility (pointers in datastructures in an array, making 32->64
442 bit compatibility very painful) has been fixed in a
443 non-backwards-compatible way. If you replace your kernel,
444 replace your rndctl executable too.
445
446 20111001:
447 the prop_*_send_syscall() functions from proplib(3) have been
448 changed and their new version is not backward compatible with the old
449 one. So ensure that all consumers of these functions (currently:
450 quota2 code and its tests) are updated together with the new lib.
451
452 20110817:
453 sparc has been changed to use GCC 4.5.3, so any objdir or
454 DESTDIR for them should be deleted before updating.
455
456 20110806:
457 i386 and amd64 have been changed to use GCC 4.5.3, so any
458 objdir or DESTDIR for them should be deleted before updating.
459
460 20110805:
461 The update to GCC 4.5.3 requires a non-trivial portion of
462 the tree to be cleaned. Best to delete both objdir and
463 DESTDIR before running this update. So far, only the
464 sparc64, mips and powerpc platforms have changed.
465
466 20110803:
467 The layout of external/public-domain/xz has changed. To do an
468 update build you will have to remove the contents of the OBJDIR
469 for external/public-domain/xz/bin by hand as the xz entry there
470 is now a directory.
471
472 20110410:
473 The configuration of src/tools/gcc has changed. To do an
474 update build you have to clean both tools/binutils and
475 tools/gcc by hand.
476
477 20110328:
478 Building the Xorg binary was moved into a subdirectory to fix
479 ordering issues with "make all". It may be necessary to remove
480 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
481 if your update build fails, as the "Xorg" entry there is now a
482 directory.
483
484 20110121:
485 Assembler files no longer use -traditional-cpp. This can break
486 the build of individual parts of the tree. This is handled
487 correctly by build.sh. Manual builds have to update /usr/share/mk
488 and re-run config(1) for any kernel configurations as needed.
489
490 20101217:
491 The tcpdump(8) program was changed to drop privileges and chroot(2)
492 by default. It may be necessary to manually update passwd(5) and
493 group(5) in order to make the program work with existing setups.
494
495 20101125:
496 The latest changes to setenv(3) dissallow setting environment
497 variables with names that contain '='. Revision 1.18 of env.c
498 assumed that this was allowed. Installing a new libc with an
499 old copy of /usr/bin/env causes env x=1 printenv | grep x= to
500 break which affects the autoconf tests for dependency finding,
501 so building gcc will end up printing:
502 checking dependency style of gcc... none
503 configure: error: no usable dependency style found
504 Fix it by rebuilding and re-installing env.
505
506 20101119:
507 Recent Xorg updates in xsrc/external/mit/ may cause various build
508 or run-time problems. Delete your entire DESTDIR and OBJDIR if you
509 have any build problems with xsrc, or problems with mismatched
510 versions between xorg-server and drivers.
511
512 20100604:
513 The update of ATF to 0.9 causes old tests written in shell to fail
514 unless they are rebuilt. If you are building with MKUPDATE=yes,
515 you need to clean the src/external/bsd/atf/tests/ and the src/tests/
516 trees by hand.
517
518 20100522:
519 Recent Xorg updates in xsrc/external/mit/ will cause various build
520 problems. Delete your entire DESTDIR and OBJDIR if you have any
521 build problems with xsrc.
522
523 20100522:
524 private section of <ctype.h> was splitted, and now mklocale(1)
525 include ctype_local.h, so you have to make cleandir in tools/mklocale.
526
527 20100520:
528 The location of the xkb compiled descriptions has changed. Please
529 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
530
531 20100222:
532 The shared objects file extension has been changed from .so to
533 .pico, in order to avoid conflicts with shared libraries names
534 libXX.so. All now stale regular .so files can be removed from
535 your object directories.
536
537 20100204:
538 The termcap database has been removed from the sources,
539 but has not been marked obsolete so it is not removed
540 from the system when upgrading.
541 As such, you will need to remove them from your object
542 and destination directories.
543
544 20091101:
545 After updating, it may be necessary to make the 'cleandir'
546 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
547 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
548 src/tools/lex/ and src/usr.bin/lex/.
549
550 20091001:
551 On amd64 you must rebuild tools (to get the new binutils)
552 before building a kernel, or the build fails on cpufunc.S.
553
554 20091001:
555 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
556 symlink, failing the build. Delete the link, and the subdir
557 it is in, and retry your build.
558
559 20090718:
560 libc build changed so that strchr() provides the extra entry
561 point for index(). Update build of libc.a (and libc_pic.a)
562 may fail because the archive contains the unwanted index.o.
563 (Similarly for strrchr() and rindex().)
564
565 20090709:
566 Native Xorg was upgraded again. Builds will probably fail again
567 without a clean objdir, at least for src/external/mit/xorg.
568
569 20090616:
570 Native Xorg was upgraded. Builds will need a clean objdir for
571 src/external/mit/xorg. Upgrading a system from sets will not
572 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
573 subdirectory has been changed into a file, and this needs to
574 be manually "rm -r"'ed before installing xbase.tgz.
575
576 20090501:
577 Several new functions were added to string.h/libc, and this
578 can cause autoconf problems during the tool build for people
579 who fail to clean out their tools objects properly. If you
580 note messages about stpcpy, stpncpy or strnlen accompanying a
581 failure during the tool build, clean out all your tools
582 objects and start again.
583
584 20090325:
585 The i386 port was switched to i486 default toolchain. This requires
586 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
587
588 20090126:
589 The __posix_fadvise50 system call changed assembly stub type. You
590 need to 'rm -f __posix_fadvise50.*' in the libc build directory
591 to avoid using the old assembly stub.
592
593 20090202:
594 pkg_install now depends on the pkgdb cache for automatic conflict
595 detection. It is recommented to rebuild the cache with
596 ``pkg_admin rebuild''.
597
598 20090110:
599 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
600 1. Make sure your kernel has COMPAT_50 in it. Build and install.
601 This is needed even in the MODULAR kernel because there is
602 conditionally compiled code in rtsock.c.
603 2. make sure build.sh completes and the binaries in a chroot work
604 before installing.
605 3. If you don't use build.sh and you build directly to root, and
606 your build breaks in the middle, don't despair. Make sure headers
607 are installed properly, and start building libraries first libc
608 and libutil, install them and then continue building all the
609 libraries in src/lib and src/gnu/lib and install them. Once
610 the new libraries are installed, you can restart the build.
611 4. If you compile packages and you notice link time warnings,
612 rebuild the required packages to update their shared libraries.
613 Any package you rebuild will require rebuilding all the packages
614 that depend on it.
615 5. Next time you run pwd_mkdb with the new binary, the file
616 will be upgraded and it will not be backwards compatible.
617 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
618 lastlogx(5)) have been versioned, and there is a heuristic
619 for utmp. You are better off removing the old files after
620 upgrading. The automated clearing of /var/run during
621 boot, and the automated rotating of files in /var/log by
622 newsyslog(8), may mean that you do not have to remove the
623 files manually.
624 7. The optional accounting file (/var/account/acct, see
625 accton(8)) has not been versioned, and will need to be
626 removed. The automatic rotation of the accounting file by
627 /etc/daily limits the bad consequences of failure to remove
628 the file.
629 8. Application software that writes time_t to binary files on
630 disk will break or need attention. Most notably: if you are
631 using PostgreSQL < 8.4, you need to dump your databases,
632 rebuild PostgreSQL with the new time_t, then restore.
633
634 20081219:
635 config(1) has been updated, and one of the files it creates -
636 swapnetbsd.o - has changed format. You need to rebuild config
637 (done automatically by build.sh) and then you need to rerun
638 config on all kernel configuration files before rebuilding those
639 kernels.
640
641 20081205:
642 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
643 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
644 set and will appear as extra files for MKX11=no update builds.
645
646 20081122:
647 On i386, various kernel options(4) in GENERIC including
648 file systems have been disabled and moved into kernel modules.
649 Before trying a new GENERIC kernel, you have to prepare the
650 following files as well as a new GENERIC kernel:
651
652 - build and install kernel modules from src/sys/modules
653
654 - install the latest bootloader, which will load a module
655 for the file system from which the kernel is loaded automatically
656
657 If you have to load your kernel from a file system which is not of
658 the same type as the root file system, you have to load the necessary
659 file system module manually on the boot prompt or in the boot.cfg file.
660
661 20080827:
662 If you built and installed a libc from sources between
663 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
664 which results in false errors reported by lint(1).
665 Since this breaks the libc build itself, manual help is
666 needed -- lint must be disabled temporarily, e.g.:
667 $ (cd lib/libc && make MKLINT=no dependall install)
668
669 20080813:
670 MKDEBUG build was broken because the .depend files did not know
671 about .go files. You need to remove all .depend files and rebuild.
672
673 20080802:
674 A regression in binary compatibility for pthread_mutex_t has
675 been fixed. Unfortunately, the price is breaking compatibility
676 for -current.
677
678 Threaded programs (using libpthread) and C++ programs (using
679 libstdc++) compiled after 20070907 and before 20080802 need to
680 be recompiled.
681
682 One way to find affected pkgsrc packages:
683
684 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
685 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
686
687 20080731:
688 WAPBL (metadata journaling support) has been added, but at this
689 time isn't backwards compatible with pre-WAPBL aware kernels
690 and userland (fsck_ffs in particular). Please make sure you
691 don't use a journaled filesystem with an older kernel/userland,
692 especially an uncleanly mounted journaled filesystem. WAPBL
693 also requires the super block to be in the UFS2 format. You
694 can use fsck_ffs -c 4 to update the superblock format.
695
696 20080721:
697 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
698 isn't defined.
699
700 20080531:
701 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
702 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
703 utility needs to be rebuilt and reinstalled as older binaries
704 won't work correctly. The following sequence of commands:
705
706 $ (cd sys/sys/ && nbmake-$arch includes)
707 $ (cd sbin/drvctl/ && nbmake-$arch clean)
708 $ (cd sbin/drvctl/ && nbmake-$arch all)
709
710 leaves new drvctl utility in sbin/drvctl build directory.
711
712 20080503:
713 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
714
715 20080521:
716 For a while, unprivileged UPDATE builds would fail to
717 succeed at the checkflist stage, complaining that
718 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
719 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
720 If you already hit this problem, update the .mk file,
721 remove ${DESTDIR}/stand/<arch>, and re-run the build.
722
723 20080303:
724 Linker warnings are now fatal if $WARNS>0.
725
726 20080126:
727 The posix_fadvise system call has been changed from an assembly
728 stub, to a c file that calls an assembly stub. You need to
729 'rm -f posix_fadvise.* .depend' in the libc build directory to
730 avoid using the old assembly stub.
731
732 20071209:
733 The acpiec(4) driver has been split into two attachments. If you
734 get ACPI errors before the attachment, please update your kernel
735 configuration file appropriately or see GENERIC for more details.
736
737 20071115:
738 The it(4) driver has been renamed to itesio(4) and the old port
739 argument specified in the kernel configuration file is not valid
740 anymore. The itesio(4) driver now uses the Super I/O address port
741 rather than the EC address port. Please update your kernel
742 configuration file appropriately or see GENERIC for more details.
743
744 20071028:
745 The pccons(4) driver has been removed from the NetBSD/shark port.
746 You need to update any custom kernel configuration file you have
747 to remove any references to pccons (which includes removing the
748 now useless XSERVER option) and replace them with the correct
749 entries for the wscons driver. See the GENERIC configuration file
750 for more details.
751
752 20070913:
753 A latent bug in dhclient/dhcpd that caused it to be unable to
754 enumerate interfaces was fixed. The bug began to cause
755 problems after 20070911 when the kernel's SIOCGIFCONF
756 implementation was repaired. From 20070529 to 20070911 racoon
757 could not enumerate interfaces. (These are noted because
758 normal kernel/userspace version matching hygiene is not
759 sufficient to avoid this problem.) Ensure that both kernel
760 and userland are from after 20070913.
761
762 20070703:
763 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
764 calls the target-specific strip program, and the logic to pass
765 down STRIP from make has been removed. This requires a
766 re-installation of tools.
767
768 20070422:
769 The way OS emulations lookup filenames inside the emulation root
770 has been changed. Rather than modify the pathname (and copy back
771 to userspace) namei() and lookup() directly check the emulation
772 root. One side effect is that absolute symlinks inside the emulated
773 root file system will be relative to that file system - unless they
774 start /../ this is useful when the emulated root is a real install
775 that has such links.
776 This might affect symlinks that have been added to reference outside
777 the emulated root.
778
779 20070412:
780 The pckbc driver on sgimips IP32 has been removed. Use macekbc
781 instead. See the GENERIC32_IP3x kernel configuration for an
782 example.
783
784 20070319:
785 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
786 on many platforms due to incorrect flags settings. If you
787 updated and built after about 20070315, do "nbmake-$arch
788 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
789 rebuild of object files that might have been built
790 incorrectly, and ensure that you have at least
791 src/lib/libc/Makefile 1.130.
792
793 20070210:
794 src/sys/sys/{sa.h,savar.h} were removed.
795 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
796 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
797 will allow dependencies on those files to get get rebuilt
798
799 20070209:
800 The threading model was changed when the newlock2 branch
801 was merged to NetBSD-current. If you boot with a new
802 kernel (version 4.99.10), then you also need a new pthread
803 library (/usr/lib/libpthread.so.0.7). If you boot with
804 an old kernel, then you need the old pthread library
805 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
806 the pthread library in sync, old threaded applications should
807 continue to work with an old or new kernel. Note that named(8)
808 is the only threaded application in the base system.
809
810 20061214:
811 Following the move of string_to_flags() and flags_to_string()
812 from the bin/ls/ sources to libutil, users doing UPDATE builds
813 will need to do a "make cleandir" in
814 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
815 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
816 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
817 as the installation images in distrib/
818 in order to excise stale references to the old stat_flags.h header
819 file in the ls sources -- stat_flags.h has been removed.
820
821 20061108:
822 The configure script used in the src/tools/gcc compiler has been
823 changed to indicate that our libc has ssp support built-in and
824 does not depend on -lssp and -lssp-nonshared. You'll need to
825 make clean in src/tools/gcc first to rebuild the compiler.
826
827 20061009:
828 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
829 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
830
831 20060814:
832 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
833 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
834 kernel configuration for an example. X servers from the last
835 few years should cope.
836
837 20060703:
838 MPACPI is no more. We always configure PCI interrupts using ACPI
839 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
840 to ACPI_SCANPCI. Thanks to work from fvdl.
841
842 20060627:
843 socket(2) has changed, and its system call has been versioned.
844 For userlands with the old version of socket(2), make sure that
845 your kernel has 'options COMPAT_30' set, or else 'bad system call'
846 errors will result.
847
848 Hints for a more successful build:
849 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
850 Use build.sh, but do not use its "expert mode":
851 This will automatically build the tools in the
852 correct order, and it will keep the tools and the
853 new build products from interfering with the running
854 system. This will allow you to ignore most of the
855 other advice in this file.
856 Build a new kernel first:
857 This makes sure that any new system calls or features
858 expected by the new userland will be present. This
859 helps to avoid critical errors when upgrading.
860 Use object directories:
861 This helps to keep stale object
862 files from polluting the build if a Makefile "forgets"
863 about one. It also makes it easier to clean up after
864 a build. It's also necessary if you want to use the
865 same source tree for multiple machines.
866 To use object directories with build.sh:
867 a) invoke build.sh with the "-M" or "-O" options.
868 To use object directories without using build.sh:
869 a) cd /usr/src ; make cleandir
870 b) Add "OBJMACHINE=yes" to /etc/mk.conf
871 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
872 d) cd /usr/src ; make build
873 Note that running "make obj" in a directory will create
874 in obj.$MACHINE directory.
875 Build to a DESTDIR:
876 This helps to keep old installed files (especially libraries)
877 from interfering with the new build.
878 To build to a DESTDIR with build.sh, use the "-D" option.
879 To build to a DESTDIR without using build.sh, set the DESTDIR
880 environment variable before running make build. It should be
881 set to the pathname of an initially empty directory.
882 Problems: if you do not use build.sh, you might need to
883 update critical utilities without using DESTDIR since
884 nothing is executed from what is installed in DESTDIR.
885 (See critical utils, below.)
886 Build often:
887 This keeps critical utilities current enough to not choke
888 on any other part of the source tree that depends on up to
889 date functionality. If you use build.sh, you should not have
890 this problem.
891
892 What to do if things don't work:
893 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
894 When things don't work there are usually a few things that commonly
895 should be done.
896 1) make includes
897 This should be done automatically by make build.
898 2) cd share/mk && make install
899 Again, automatically done by make build.
900
901 Failsafe rebuild of a small part of the tree:
902 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
903 To make sure you rebuild something correctly you want to do
904 something like the following:
905 1) Make sure the includes and .mk files are up to date.
906 2) Make sure any program used to build the particular
907 utility is up to date. (yacc, lex, etc...)
908 3) cd ...path/to/util...
909 make cleandir
910 rm ...all obj directories...
911 make cleandir # yes, again
912 make obj
913 make depend && make
914
915 Failsafe rebuild of the entire tree:
916 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
917 If you really want to make sure the source tree is clean and
918 ready for a build try the following. Note that sourcing /etc/mk.conf
919 (a make(1) Makefile) in this manner is not right, and will not work
920 for anyone who uses any make(1) features in /etc/mk.conf.
921

955 Other problems and possible solutions:
956 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
957 Symptom:Complaints involving a Makefile.
958 Fix: Rebuild usr.bin/make:

963 Fix: Make sure .mk files are up to date.
964 cd share/mk && make install
965
966 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
967 Fix: Rebuild usr.bin/config
968
969 Symptom:
970 Fix: Rebuild usr.bin/yacc
971
972 Symptom:
973 Fix: Rebuild usr.bin/lex
974
975 Symptom:
976 Fix: rm /usr/lib/libbfd.a
977
978 Symptom:Obsolete intermediate files are used during compilation
979 Fix: Try the following sequence of commands in the directory in question.
980 make cleandir; rm `make print-objdir`; make cleandir; make obj
981 (If you built the tree without "make obj" in the past, obsolete files
982 may remain. The command tries to clean everything up)

1007 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
1008 No such file or directory.
1009 Cause: If a directory is created by mistake, then it is sometimes
1010 deleted from the CVS repository using administrative commands
1011 that bypass the normal cvs access controls. If your cvs working tree
1012 contains references to a directory that has been deleted on the
1013 server in this way, then "cvs update" reports this error.
1014 Fix: Recursively delete the affected directory from your working tree
1015 and try the update again.
