UPDATING revision 1.311 1 $NetBSD: UPDATING,v 1.311 2020/08/12 06:48:50 mrg Exp $
2
3 This file (UPDATING) is intended to be a brief reference to recent
4 changes that might cause problems in the build process, and a guide for
5 what to do if something doesn't work.
6
7 For a more detailed description of the recommended way to build NetBSD
8 using build.sh, see the BUILDING file.
9
10 Note that much of the advice in this UPDATING file was written before
11 build.sh existed. Nevertheless, the advice here may be useful for
12 working around specific problems with build.sh.
13
14 Sections are marked with "^^^^^". After the section on "Recent changes"
15 are several sections containing more general information.

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

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

941 Other problems and possible solutions:
942 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
943 Symptom:Complaints involving a Makefile.
944 Fix: Rebuild usr.bin/make:

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

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

989 Symptom:Update build fails in src/tools/gcc complaining that a variable
990 (e.g. CPPFLAGS) has changed since the previous run.
991 Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
992
993 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
994 No such file or directory.
995 Cause: If a directory is created by mistake, then it is sometimes
996 deleted from the CVS repository using administrative commands
997 that bypass the normal cvs access controls. If your cvs working tree
998 contains references to a directory that has been deleted on the
999 server in this way, then "cvs update" reports this error.
1000 Fix: Recursively delete the affected directory from your working tree
1001 and try the update again.
