UPDATING revision 1.309 1 $NetBSD: UPDATING,v 1.309 2020/06/15 03:39:00 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*. You need to manually:
24 mv /var/db/bl{a,o}cklist.db
25 fix npf rules that mention blacklist
26 fix rc.conf variables
27
28 20200601:
29 Due to a mistake in LIBISPRIVATE handling, .so libraries were
30 created in the build directories and need cleaning.
31
32 20200311:
33 GCC 8 ports will need cleaning in src/tools/gcc and
34 src/external/gpl3/gcc due to GCC 8.4 update.
35
36 20191118:
37 More architectures were switched to gcc8:
38 i386, ia64 powerpc64, sparc, sparc64, arm
39 The same comments as in 20191022 apply.
40
41 20191112:
42 The LLVM update requires a clean rebuild for all architectures using
43 LLVM during the tools build phase (i386, amd64, aarch64).
44
45 20191022:
46 Ports amd64 and aarch64 switched to GCC 8.3 by default.
47 In-place ("expert mode", build.sh -E) builds are not supported
48 when going from a GCC 7 userland to GCC 8. Do a regular
49 build to a different DESTDIR (or preferably: build.sh -U) at least
50 once and install sets, or download comp.{tar.xz,tgz} from the
51 daily builds and install that before doing the next in-place build.
52
53 20191001:
54 GCC 8.3 was imported. Builds of src/tools/gcc may fail if
55 old builds with GCC 7 output now uses GCC 8. Clean this
56 directory, and also clean src/external/gpl3/gcc.
57
58 20190903:
59 Files with names that coincide with existing files' names on
60 case-insensitive file systems were inadvertently committed, for
61 radeon GPU firmware. We cannot mark these as obsolete for
62 postinstall to fix, so if you updated src since 2019-08-26, and
63 ran build.sh distribution or ran build.sh release, you must
64 manually delete the following files in your DESTDIR (which is
65 usually $OBJDIR/destir.$ARCH), or from / if you have installed
66 them:

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

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

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

988 Symptom:Update build fails in src/tools/gcc complaining that a variable
989 (e.g. CPPFLAGS) has changed since the previous run.
990 Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.

992 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
993 No such file or directory.
994 Cause: If a directory is created by mistake, then it is sometimes
995 deleted from the CVS repository using administrative commands
996 that bypass the normal cvs access controls. If your cvs working tree
997 contains references to a directory that has been deleted on the
998 server in this way, then "cvs update" reports this error.
999 Fix: Recursively delete the affected directory from your working tree
1000 and try the update again.
