UPDATING revision 1.310 1 $NetBSD: UPDATING,v 1.310 2020/06/15 21:52:03 christos 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 20200614:
23 blacklist* has been renamed to blocklist*. postinstall(8)
24 should handle the migration
25
26 20200601:
27 Due to a mistake in LIBISPRIVATE handling, .so libraries were
28 created in the build directories and need cleaning.
29
30 20200311:
31 GCC 8 ports will need cleaning in src/tools/gcc and
32 src/external/gpl3/gcc due to GCC 8.4 update.
33
34 20191118:
35 More architectures were switched to gcc8:
36 i386, ia64 powerpc64, sparc, sparc64, arm
37 The same comments as in 20191022 apply.
38
39 20191112:
40 The LLVM update requires a clean rebuild for all architectures using
41 LLVM during the tools build phase (i386, amd64, aarch64).
42
43 20191022:
44 Ports amd64 and aarch64 switched to GCC 8.3 by default.
45 In-place ("expert mode", build.sh -E) builds are not supported
46 when going from a GCC 7 userland to GCC 8. Do a regular
47 build to a different DESTDIR (or preferably: build.sh -U) at least
48 once and install sets, or download comp.{tar.xz,tgz} from the
49 daily builds and install that before doing the next in-place build.
50
51 20191001:
52 GCC 8.3 was imported. Builds of src/tools/gcc may fail if
53 old builds with GCC 7 output now uses GCC 8. Clean this
54 directory, and also clean src/external/gpl3/gcc.
55
56 20190903:
57 Files with names that coincide with existing files' names on
58 case-insensitive file systems were inadvertently committed, for
59 radeon GPU firmware. We cannot mark these as obsolete for
60 postinstall to fix, so if you updated src since 2019-08-26, and
61 ran build.sh distribution or ran build.sh release, you must
62 manually delete the following files in your DESTDIR (which is
63 usually $OBJDIR/destir.$ARCH), or from / if you have installed
64 them:

133 We will re-import these radeon firmware images another way
134 later.
135
136 20190727:
137 The uefi bootloader has gained tftp support and needs a clean
138 build. If you do update builds, manually clean its object
139 directory by something like:
140 cd sys/arch/i386/stand/efiboot && make clean
141
142 20190723:
143 The jemalloc allocator in libc is now build without extended
144 debugging (for performance reasons). In update builds make sure
145 to rebuild it completly, by removing all affected object files,
146 including compat builds, something like:
147 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
148
149 20190207:
150 GCC 7 switched for many ports. Update builds are likely to fail.
151
152 20180924:
153 A newer OpenSSL version has been imported. If you are doing
154 update builds, make sure to remove all old obj dirs, like:
155 cd /usr/obj && find . -type d -name openssl | xargs rm -rf
156
157 20180717:
158 On aarch64 int64_t and related types have changed from long long
159 to long. This requires recompiling all C++ binaries.
160
161 20180713:
162 On amd64 and i386 static binaries are now build position
163 independend. This requires recompilation of all object
164 files used to create the crunched /rescue binary.
165 Clean the rescue directory in your obj directory before
166 doing an update build, otherwise linking will fail.
167
168 20180414:
169 Existing binutils was migrated to binutils.old. Manual
170 removal of tools/binutils objects directory may be required
171 to fix tools build failure.
172
173 20180311:
174 bdftopcf was updated and may need cleaning in the
175 src/external/mit/xorg/tools/bdftopcf subdirectory if there are
176 link errors.
177
178 20180212:
179 between OpenSSL and GCC updates, many things may fail to build.
180 any failure that looks like GCC or openssl is best handled by
181 a clean destdir and objdir. Full cleandir and destdir deletion
182 is recommended if build failures occur.
183
184 20171225:
185 removal of the vadvise syscall requires manual removal of all
186 associated files from the libc build object directory (including
187 the .depend files) - a command like:
188 cd $OBJ && find . -type d -name libc | xargs rm -rf
189 For architectures that support multiple "compat" binary targets,
190 you'll need to cleanup both the regular libc directory and the
191 compat ones (the above command will do that).
192
193 20171010:
194 a change to the build structure of external/bsd/acpica/bin/iasl
195 means that its objdir (or *.d and .depend at least) might need
196 to be manually removed - or a build done once without -u.
197
198 20170822:
199 a new version of GMP has been imported and probably
200 will break parts of builds related to themselves or GCC, both
201 in the tools and the native section. Remove all GCC, GMP, MPFR
202 and MPC objdirs or build once without -u.
203
204 20170816:
205 a new version of MPFR and MPC have been imported and probably
206 will break parts of builds related to themselves or GCC, both
207 in the tools and the native section. Remove all GCC, GMP, MPFR
208 and MPC objdirs or build once without -u.
209
210 20170402:
211 a new version of dhcpcd has been imported, which does not support
212 update builds from the previous version. Remove your
213 external/bsd/dhcpcd object dir or build once without -u.
214
215 20170211:
216 a new terminfo database has been imported.
217 The structure of it has changed slightly from prior versions and
218 an updated tic tool is required.
219 If you build.sh, don't use -u
220
221 20170207:
222 various arch dependent libc/exect.S files were removed
223 Either remove the obj directories (lib/libc and compat/amd64/i386/lib
224 if it exists) or do a clean build.
225 (This is a bug in the make system, it should be corrected without
226 human intervention, but isn't.)
227
228 20170104:
229 xinput build options have changed.
230 Remove the obj directory (external/mit/xorg/bin/xinput)
231 if you build.sh -u
232
233 20170103:
234 a new version of flex has been imported.
235 Remove the file from obj (external/bsd/flex)
236 if you build.sh -u
237
238 20161014:
239 a new version of OpenSSL has been imported.
240 Remove the files from obj (crypto/external/bsd/openssl)
241 if you build.sh -u
242
243 20161009:
244 a new version of dhcpcd has been imported with slightly changed
245 build infrastructure. When doing a build.sh -u this requires
246 pruning the external/bsd/dhcpcd objdir.
247
248 20160914:
249 i386, amd64, shark, ofppc and macppc have joined shark and x68k
250 ports in using xorg-server 1.18. This requires a clean destdir
251 and a clean objdir.
252
253 20160527:
254 i386 needs a full cleandir or objdir deletion because PIE has
255 been enabled. (see the amd64 entry two down for further info)
256
257 20160418:
258 libedit needs manual removal of all autogenerated files since
259 some of them are not autogenerated anymore. Remember that there
260 might be two copies of libedit if your platform builds "compat".
261
262 20160410:
263 amd64 needs full "make cleandir" or deletion of objdir now that
264 PIE has been enabled for amd64. PIE, or position-independent
265 executables, means all code, including executables and not just
266 shared libraries, is position-independent and hence able to be
267 relocated by ASLR, address space layout randomization.
268
269 The change was made in Makefile variables for compiler and
270 linker flags, for which make(1) does not record dependencies,
271 hence it is unable to detect that all .o files need rebuilding.
272
273 Partial rebuilds with some modified source files will likely
274 fail when linking executables, since the linker refuses to mix
275 position-independent code with position-dependent code in
276 position-independent executables:
277
278 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
279
280 20160401:
281 Ports switching to GCC 5.3 will need a full "make cleandir".
282 Some people have found that cleandir is not sufficient, so if
283 in doubt delete the entire object directory tree for gcc.
284
285 20160306:
286 NetBSD's regexp implementation is now part of libnbcompat.
287 Nblex, nbm4, nbpax, nbsed use it and they may crash on
288 non-NetBSD hosts if linked with stale object files produced
289 while they included a non-NetBSD regex.h.
290 In any case, you should "make cleandir" at least these tools
291 before updating your toolchain.
292
293 20160125:
294 Dtrace has been enabled by default on some architectures.
295 When doing an update build, make sure to clean the etc/mtree
296 object directory before starting the build - otherwise the
297 needed directories in destdir will not be created.
298 An easy way to do this is:
299 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
300
301 20150818:
302 New acpica requires "make cleandir" in src/external/bsd/acpica
303 again.
304
305 20150413:
306 New acpica requires "make cleandir" and reinstalling yacc
307 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
308 also "make cleandir" in /usr/src/external/bsd/acpica.
309
310 20150404:
311 Lint changes require a full rebuild of the tool, so make
312 sure to build without -u option to build.sh, or manually
313 do a make cleandir in src/tools/lint1 and
314 src/usr.bin/xlint.
315
316 20150310:
317 Improvements to openssl for arm mean that update builds of
318 the openssl libraries will fail. A make cleandir in
319 external/bsd/openssl/lib is needed
320
321 20141026:
322 A mishap during the import of pppd may cause your corruption
323 in your cvs directory if you happened to do a cvs update
324 during a short period of time. To fix, just remove the
325 directory src/external/bsd/ppp/dist/pppd completely
326 and let cvs restore it on next update.
327
328 20140721:
329 The src/external/mit/lua/src directory was accidentally created
330 and then deleted in the CVS repository. If you get errors like
331
332 cvs [update aborted]: cannot open directory
333 /cvsroot/src/external/mit/lua/src: No such file or directory
334
335 then delete your local copy of that directory tree and try again.
336
337 20140530:
338 ARM eABI switched to DWARF based exception handling. This requires
339 rebuilding all C++ code. It is strongly advised to do a clean build.
340
341 20140131:
342 The new compiler_rt/libc integration moved a few things. It is strongly
343 advised to do a clean build. At least lib/libc, the compat version(s)
344 of libc, libkern, rump and the kernels need to be cleaned.
345
346 20131227:
347 1. The new ntpd runs in a restricted mode to prevent amplification
348 attacks. If you need ntpdc to work you need to explicitly enable
349 mode7 in your config file. Make sure you put the necessary restrict
350 statements to avoid being exposed.
351 2. strncat has moved from lib/libc to common/lib/libc; you might need
352 to make clean in libc
353
354 20131129:
355 The GMP sources were updated, and builds will likely fail without
356 cleaning their build trees for both tools and in-tree, like below.
357
358 20131128:
359 The MPC and MPFR sources were updated, and builds may require their
360 tools and in-tree directories cleaned for successful updates.
361
362 20130605:
363 The kernel option FAST_IPSEC no longer exists, it's been renamed
364 to IPSEC (and the older IPSEC version removed).
365
366 20130605:
367 Previous freetype installations eroneously installed private
368 header files. If you are building against a non-empty $DESTDIR,
369 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
370
371 20130531:
372 The xdm update may cause build failure due to xdm.man being
373 in the obj tree. Make sure to ensure any like this:
374 nbmake: nbmake: don't know how to make xdm.man. Stop
375 is fixed by deleting the xdm.man in the obj tree.
376
377 20130530:
378 Updates of many xsrc packages will leave old .pc files around.
379 Best to clean out the xsrc objdir entirely before rebuilds.
380
381 20130301:
382 The removal of netiso requires manual removal of /usr/include/netiso
383 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
384
385 20120726:
386 The update of OpenSSL requires cleaning both the OpenSSL build
387 directory and DESTDIR. *Even non-update builds require cleaning
388 DESTDIR.* Builds done without taking these steps may fail, or in
389 some cases may succeed and install broken OpenSSL libraries that
390 cause third-party software to link incorrectly and/or crash.
391
392 20120507:
393 The database schema for makemandb was changed. You will
394 need to update the database using 'makemandb -f' or wait
395 for the next weekly run to fix it.
396
397 20120319:
398 sys/conf/Makefile.kern.inc has been modified to adjust the
399 size of db_symtab automatically. You need to update dbsym in
400 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
401 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
402 mk.conf.
403
404 20120216:
405 Default for MKCATPAGES changed to NO. Update builds will fail
406 unless DESTDIR is cleaned manually. If you built between 20120207
407 and 20120216, daily and weekly could have created an unreadable
408 /var/db/man.db index for apropos. Running makemandb -f or
409 the next run of weekly will fix it.
410
411 20111227:
412 If you built between 20111225 and 20111227 you need to remove
413 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
414 bump has been reverted.
415
416 20111125:
417 The "rnd" pseudodevice has been added to sys/conf/std, which
418 means it should no longer be explicitly listed in kernel
419 configuration files. The line "pseudo-device rnd" should be
420 removed from any custom kernel config files users may have.
421
422 20111119:
423 A problem with the datastructures used by the rndctl(8)
424 utility (pointers in datastructures in an array, making 32->64
425 bit compatibility very painful) has been fixed in a
426 non-backwards-compatible way. If you replace your kernel,
427 replace your rndctl executable too.
428
429 20111001:
430 the prop_*_send_syscall() functions from proplib(3) have been
431 changed and their new version is not backward compatible with the old
432 one. So ensure that all consumers of these functions (currently:
433 quota2 code and its tests) are updated together with the new lib.
434
435 20110817:
436 sparc has been changed to use GCC 4.5.3, so any objdir or
437 DESTDIR for them should be deleted before updating.
438
439 20110806:
440 i386 and amd64 have been changed to use GCC 4.5.3, so any
441 objdir or DESTDIR for them should be deleted before updating.
442
443 20110805:
444 The update to GCC 4.5.3 requires a non-trivial portion of
445 the tree to be cleaned. Best to delete both objdir and
446 DESTDIR before running this update. So far, only the
447 sparc64, mips and powerpc platforms have changed.
448
449 20110803:
450 The layout of external/public-domain/xz has changed. To do an
451 update build you will have to remove the contents of the OBJDIR
452 for external/public-domain/xz/bin by hand as the xz entry there
453 is now a directory.
454
455 20110410:
456 The configuration of src/tools/gcc has changed. To do an
457 update build you have to clean both tools/binutils and
458 tools/gcc by hand.
459
460 20110328:
461 Building the Xorg binary was moved into a subdirectory to fix
462 ordering issues with "make all". It may be necessary to remove
463 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
464 if your update build fails, as the "Xorg" entry there is now a
465 directory.
466
467 20110121:
468 Assembler files no longer use -traditional-cpp. This can break
469 the build of individual parts of the tree. This is handled
470 correctly by build.sh. Manual builds have to update /usr/share/mk
471 and re-run config(1) for any kernel configurations as needed.
472
473 20101217:
474 The tcpdump(8) program was changed to drop privileges and chroot(2)
475 by default. It may be necessary to manually update passwd(5) and
476 group(5) in order to make the program work with existing setups.
477
478 20101125:
479 The latest changes to setenv(3) dissallow setting environment
480 variables with names that contain '='. Revision 1.18 of env.c
481 assumed that this was allowed. Installing a new libc with an
482 old copy of /usr/bin/env causes env x=1 printenv | grep x= to
483 break which affects the autoconf tests for dependency finding,
484 so building gcc will end up printing:
485 checking dependency style of gcc... none
486 configure: error: no usable dependency style found
487 Fix it by rebuilding and re-installing env.

489 20101119:
490 Recent Xorg updates in xsrc/external/mit/ may cause various build
491 or run-time problems. Delete your entire DESTDIR and OBJDIR if you
492 have any build problems with xsrc, or problems with mismatched
493 versions between xorg-server and drivers.
494
495 20100604:
496 The update of ATF to 0.9 causes old tests written in shell to fail
497 unless they are rebuilt. If you are building with MKUPDATE=yes,
498 you need to clean the src/external/bsd/atf/tests/ and the src/tests/
499 trees by hand.
500
501 20100522:
502 Recent Xorg updates in xsrc/external/mit/ will cause various build
503 problems. Delete your entire DESTDIR and OBJDIR if you have any
504 build problems with xsrc.
505
506 20100522:
507 private section of <ctype.h> was splitted, and now mklocale(1)
508 include ctype_local.h, so you have to make cleandir in tools/mklocale.
509
510 20100520:
511 The location of the xkb compiled descriptions has changed. Please
512 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
513
514 20100222:
515 The shared objects file extension has been changed from .so to
516 .pico, in order to avoid conflicts with shared libraries names
517 libXX.so. All now stale regular .so files can be removed from
518 your object directories.
519
520 20100204:
521 The termcap database has been removed from the sources,
522 but has not been marked obsolete so it is not removed
523 from the system when upgrading.
524 As such, you will need to remove them from your object
525 and destination directories.
526
527 20091101:
528 After updating, it may be necessary to make the 'cleandir'
529 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
530 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
531 src/tools/lex/ and src/usr.bin/lex/.
532
533 20091001:
534 On amd64 you must rebuild tools (to get the new binutils)
535 before building a kernel, or the build fails on cpufunc.S.
536
537 20091001:
538 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
539 symlink, failing the build. Delete the link, and the subdir
540 it is in, and retry your build.
541
542 20090718:
543 libc build changed so that strchr() provides the extra entry
544 point for index(). Update build of libc.a (and libc_pic.a)
545 may fail because the archive contains the unwanted index.o.
546 (Similarly for strrchr() and rindex().)
547
548 20090709:
549 Native Xorg was upgraded again. Builds will probably fail again
550 without a clean objdir, at least for src/external/mit/xorg.
551
552 20090616:
553 Native Xorg was upgraded. Builds will need a clean objdir for
554 src/external/mit/xorg. Upgrading a system from sets will not
555 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
556 subdirectory has been changed into a file, and this needs to
557 be manually "rm -r"'ed before installing xbase.tgz.
558
559 20090501:
560 Several new functions were added to string.h/libc, and this
561 can cause autoconf problems during the tool build for people
562 who fail to clean out their tools objects properly. If you
563 note messages about stpcpy, stpncpy or strnlen accompanying a
564 failure during the tool build, clean out all your tools
565 objects and start again.
566
567 20090325:
568 The i386 port was switched to i486 default toolchain. This requires
569 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
570
571 20090126:
572 The __posix_fadvise50 system call changed assembly stub type. You
573 need to 'rm -f __posix_fadvise50.*' in the libc build directory
574 to avoid using the old assembly stub.
575
576 20090202:
577 pkg_install now depends on the pkgdb cache for automatic conflict
578 detection. It is recommented to rebuild the cache with
579 ``pkg_admin rebuild''.
580
581 20090110:
582 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
583 1. Make sure your kernel has COMPAT_50 in it. Build and install.
584 This is needed even in the MODULAR kernel because there is
585 conditionally compiled code in rtsock.c.
586 2. make sure build.sh completes and the binaries in a chroot work
587 before installing.
588 3. If you don't use build.sh and you build directly to root, and
589 your build breaks in the middle, don't despair. Make sure headers
590 are installed properly, and start building libraries first libc
591 and libutil, install them and then continue building all the
592 libraries in src/lib and src/gnu/lib and install them. Once
593 the new libraries are installed, you can restart the build.
594 4. If you compile packages and you notice link time warnings,
595 rebuild the required packages to update their shared libraries.
596 Any package you rebuild will require rebuilding all the packages
597 that depend on it.
598 5. Next time you run pwd_mkdb with the new binary, the file
599 will be upgraded and it will not be backwards compatible.
600 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
601 lastlogx(5)) have been versioned, and there is a heuristic
602 for utmp. You are better off removing the old files after
603 upgrading. The automated clearing of /var/run during
604 boot, and the automated rotating of files in /var/log by
605 newsyslog(8), may mean that you do not have to remove the
606 files manually.
607 7. The optional accounting file (/var/account/acct, see
608 accton(8)) has not been versioned, and will need to be
609 removed. The automatic rotation of the accounting file by
610 /etc/daily limits the bad consequences of failure to remove
611 the file.
612 8. Application software that writes time_t to binary files on
613 disk will break or need attention. Most notably: if you are
614 using PostgreSQL < 8.4, you need to dump your databases,
615 rebuild PostgreSQL with the new time_t, then restore.
616
617 20081219:
618 config(1) has been updated, and one of the files it creates -
619 swapnetbsd.o - has changed format. You need to rebuild config
620 (done automatically by build.sh) and then you need to rerun
621 config on all kernel configuration files before rebuilding those
622 kernels.
623
624 20081205:
625 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
626 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
627 set and will appear as extra files for MKX11=no update builds.
628
629 20081122:
630 On i386, various kernel options(4) in GENERIC including
631 file systems have been disabled and moved into kernel modules.
632 Before trying a new GENERIC kernel, you have to prepare the
633 following files as well as a new GENERIC kernel:
634
635 - build and install kernel modules from src/sys/modules
636
637 - install the latest bootloader, which will load a module
638 for the file system from which the kernel is loaded automatically
639
640 If you have to load your kernel from a file system which is not of
641 the same type as the root file system, you have to load the necessary
642 file system module manually on the boot prompt or in the boot.cfg file.
643
644 20080827:
645 If you built and installed a libc from sources between
646 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
647 which results in false errors reported by lint(1).
648 Since this breaks the libc build itself, manual help is
649 needed -- lint must be disabled temporarily, e.g.:
650 $ (cd lib/libc && make MKLINT=no dependall install)
651
652 20080813:
653 MKDEBUG build was broken because the .depend files did not know
654 about .go files. You need to remove all .depend files and rebuild.
655
656 20080802:
657 A regression in binary compatibility for pthread_mutex_t has
658 been fixed. Unfortunately, the price is breaking compatibility
659 for -current.
660
661 Threaded programs (using libpthread) and C++ programs (using
662 libstdc++) compiled after 20070907 and before 20080802 need to
663 be recompiled.
664
665 One way to find affected pkgsrc packages:
666
667 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
668 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
669
670 20080731:
671 WAPBL (metadata journaling support) has been added, but at this
672 time isn't backwards compatible with pre-WAPBL aware kernels
673 and userland (fsck_ffs in particular). Please make sure you
674 don't use a journaled filesystem with an older kernel/userland,
675 especially an uncleanly mounted journaled filesystem. WAPBL
676 also requires the super block to be in the UFS2 format. You
677 can use fsck_ffs -c 4 to update the superblock format.
678
679 20080721:
680 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
681 isn't defined.
682
683 20080531:
684 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
685 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
686 utility needs to be rebuilt and reinstalled as older binaries
687 won't work correctly. The following sequence of commands:
688
689 $ (cd sys/sys/ && nbmake-$arch includes)
690 $ (cd sbin/drvctl/ && nbmake-$arch clean)
691 $ (cd sbin/drvctl/ && nbmake-$arch all)
692
693 leaves new drvctl utility in sbin/drvctl build directory.
694
695 20080503:
696 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
697
698 20080521:
699 For a while, unprivileged UPDATE builds would fail to
700 succeed at the checkflist stage, complaining that
701 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
702 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
703 If you already hit this problem, update the .mk file,
704 remove ${DESTDIR}/stand/<arch>, and re-run the build.
705
706 20080303:
707 Linker warnings are now fatal if $WARNS>0.
708
709 20080126:
710 The posix_fadvise system call has been changed from an assembly
711 stub, to a c file that calls an assembly stub. You need to
712 'rm -f posix_fadvise.* .depend' in the libc build directory to
713 avoid using the old assembly stub.
714
715 20071209:
716 The acpiec(4) driver has been split into two attachments. If you
717 get ACPI errors before the attachment, please update your kernel
718 configuration file appropriately or see GENERIC for more details.
719
720 20071115:
721 The it(4) driver has been renamed to itesio(4) and the old port
722 argument specified in the kernel configuration file is not valid
723 anymore. The itesio(4) driver now uses the Super I/O address port
724 rather than the EC address port. Please update your kernel
725 configuration file appropriately or see GENERIC for more details.
726
727 20071028:
728 The pccons(4) driver has been removed from the NetBSD/shark port.
729 You need to update any custom kernel configuration file you have
730 to remove any references to pccons (which includes removing the
731 now useless XSERVER option) and replace them with the correct
732 entries for the wscons driver. See the GENERIC configuration file
733 for more details.
734
735 20070913:
736 A latent bug in dhclient/dhcpd that caused it to be unable to
737 enumerate interfaces was fixed. The bug began to cause
738 problems after 20070911 when the kernel's SIOCGIFCONF
739 implementation was repaired. From 20070529 to 20070911 racoon
740 could not enumerate interfaces. (These are noted because
741 normal kernel/userspace version matching hygiene is not
742 sufficient to avoid this problem.) Ensure that both kernel
743 and userland are from after 20070913.
744
745 20070703:
746 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
747 calls the target-specific strip program, and the logic to pass
748 down STRIP from make has been removed. This requires a
749 re-installation of tools.
750
751 20070422:
752 The way OS emulations lookup filenames inside the emulation root
753 has been changed. Rather than modify the pathname (and copy back
754 to userspace) namei() and lookup() directly check the emulation
755 root. One side effect is that absolute symlinks inside the emulated
756 root file system will be relative to that file system - unless they
757 start /../ this is useful when the emulated root is a real install
758 that has such links.
759 This might affect symlinks that have been added to reference outside
760 the emulated root.
761
762 20070412:
763 The pckbc driver on sgimips IP32 has been removed. Use macekbc
764 instead. See the GENERIC32_IP3x kernel configuration for an
765 example.
766
767 20070319:
768 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
769 on many platforms due to incorrect flags settings. If you
770 updated and built after about 20070315, do "nbmake-$arch
771 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
772 rebuild of object files that might have been built
773 incorrectly, and ensure that you have at least
774 src/lib/libc/Makefile 1.130.
775
776 20070210:
777 src/sys/sys/{sa.h,savar.h} were removed.
778 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
779 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
780 will allow dependencies on those files to get get rebuilt
781
782 20070209:
783 The threading model was changed when the newlock2 branch
784 was merged to NetBSD-current. If you boot with a new
785 kernel (version 4.99.10), then you also need a new pthread
786 library (/usr/lib/libpthread.so.0.7). If you boot with
787 an old kernel, then you need the old pthread library
788 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
789 the pthread library in sync, old threaded applications should
790 continue to work with an old or new kernel. Note that named(8)
791 is the only threaded application in the base system.
792
793 20061214:
794 Following the move of string_to_flags() and flags_to_string()
795 from the bin/ls/ sources to libutil, users doing UPDATE builds
796 will need to do a "make cleandir" in
797 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
798 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
799 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
800 as the installation images in distrib/
801 in order to excise stale references to the old stat_flags.h header
802 file in the ls sources -- stat_flags.h has been removed.
803
804 20061108:
805 The configure script used in the src/tools/gcc compiler has been
806 changed to indicate that our libc has ssp support built-in and
807 does not depend on -lssp and -lssp-nonshared. You'll need to
808 make clean in src/tools/gcc first to rebuild the compiler.
809
810 20061009:
811 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
812 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
813
814 20060814:
815 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
816 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
817 kernel configuration for an example. X servers from the last
818 few years should cope.
819
820 20060703:
821 MPACPI is no more. We always configure PCI interrupts using ACPI
822 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
823 to ACPI_SCANPCI. Thanks to work from fvdl.
824
825 20060627:
826 socket(2) has changed, and its system call has been versioned.
827 For userlands with the old version of socket(2), make sure that
828 your kernel has 'options COMPAT_30' set, or else 'bad system call'
829 errors will result.
830
831 Hints for a more successful build:
832 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
833 Use build.sh, but do not use its "expert mode":
834 This will automatically build the tools in the
835 correct order, and it will keep the tools and the
836 new build products from interfering with the running
837 system. This will allow you to ignore most of the
838 other advice in this file.
839 Build a new kernel first:
840 This makes sure that any new system calls or features
841 expected by the new userland will be present. This
842 helps to avoid critical errors when upgrading.
843 Use object directories:
844 This helps to keep stale object
845 files from polluting the build if a Makefile "forgets"
846 about one. It also makes it easier to clean up after
847 a build. It's also necessary if you want to use the
848 same source tree for multiple machines.
849 To use object directories with build.sh:
850 a) invoke build.sh with the "-M" or "-O" options.
851 To use object directories without using build.sh:
852 a) cd /usr/src ; make cleandir
853 b) Add "OBJMACHINE=yes" to /etc/mk.conf
854 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
855 d) cd /usr/src ; make build
856 Note that running "make obj" in a directory will create
857 in obj.$MACHINE directory.
858 Build to a DESTDIR:
859 This helps to keep old installed files (especially libraries)
860 from interfering with the new build.
861 To build to a DESTDIR with build.sh, use the "-D" option.
862 To build to a DESTDIR without using build.sh, set the DESTDIR
863 environment variable before running make build. It should be
864 set to the pathname of an initially empty directory.
865 Problems: if you do not use build.sh, you might need to
866 update critical utilities without using DESTDIR since
867 nothing is executed from what is installed in DESTDIR.
868 (See critical utils, below.)
869 Build often:
870 This keeps critical utilities current enough to not choke
871 on any other part of the source tree that depends on up to
872 date functionality. If you use build.sh, you should not have
873 this problem.
874
875 What to do if things don't work:
876 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
877 When things don't work there are usually a few things that commonly
878 should be done.
879 1) make includes
880 This should be done automatically by make build.
881 2) cd share/mk && make install
882 Again, automatically done by make build.
883
884 Failsafe rebuild of a small part of the tree:
885 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
886 To make sure you rebuild something correctly you want to do
887 something like the following:
888 1) Make sure the includes and .mk files are up to date.
889 2) Make sure any program used to build the particular
890 utility is up to date. (yacc, lex, etc...)
891 3) cd ...path/to/util...
892 make cleandir
893 rm ...all obj directories...
894 make cleandir # yes, again
895 make obj
896 make depend && make
897
898 Failsafe rebuild of the entire tree:
899 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
900 If you really want to make sure the source tree is clean and
901 ready for a build try the following. Note that sourcing /etc/mk.conf
902 (a make(1) Makefile) in this manner is not right, and will not work
903 for anyone who uses any make(1) features in /etc/mk.conf.
904

938 Other problems and possible solutions:
939 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
940 Symptom:Complaints involving a Makefile.
941 Fix: Rebuild usr.bin/make:
942 cd usr.bin/make && make && make install
943 Or, a failsafe method if that doesn't work:
944 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
945
946 Fix: Make sure .mk files are up to date.
947 cd share/mk && make install
948
949 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
950 Fix: Rebuild usr.bin/config
951
952 Symptom:

957
958 Symptom:
959 Fix: rm /usr/lib/libbfd.a
960
961 Symptom:Obsolete intermediate files are used during compilation
962 Fix: Try the following sequence of commands in the directory in question.
963 make cleandir; rm `make print-objdir`; make cleandir; make obj
964 (If you built the tree without "make obj" in the past, obsolete files
965 may remain. The command tries to clean everything up)

979
980 Symptom:undefined reference to `getprogname' or `setprogname'
981 Fix: Rebuild and install lib/libc
982
983 Symptom:lint does not understand the '-X' option
984 Fix: May need to build & install libs with NOLINT=1 before rebuilding lint
985
986 Symptom:Update build fails in src/tools/gcc complaining that a variable
987 (e.g. CPPFLAGS) has changed since the previous run.
988 Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.

990 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
991 No such file or directory.
992 Cause: If a directory is created by mistake, then it is sometimes
993 deleted from the CVS repository using administrative commands
994 that bypass the normal cvs access controls. If your cvs working tree
995 contains references to a directory that has been deleted on the
996 server in this way, then "cvs update" reports this error.
997 Fix: Recursively delete the affected directory from your working tree
998 and try the update again.
