UPDATING revision 1.306 1 $NetBSD: UPDATING,v 1.306 2019/11/18 15:42:26 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.

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

121 We will re-import these radeon firmware images another way
122 later.
123
124 20190727:
125 The uefi bootloader has gained tftp support and needs a clean
126 build. If you do update builds, manually clean its object
127 directory by something like:
128 cd sys/arch/i386/stand/efiboot && make clean
129
130 20190723:
131 The jemalloc allocator in libc is now build without extended
132 debugging (for performance reasons). In update builds make sure
133 to rebuild it completly, by removing all affected object files,
134 including compat builds, something like:
135 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
136
137 20190207:
138 GCC 7 switched for many ports. Update builds are likely to fail.
139
140 20180924:
141 A newer OpenSSL version has been imported. If you are doing
142 update builds, make sure to remove all old obj dirs, like:
143 cd /usr/obj && find . -type d -name openssl | xargs rm -rf
144
145 20180717:
146 On aarch64 int64_t and related types have changed from long long
147 to long. This requires recompiling all C++ binaries.
148
149 20180713:
150 On amd64 and i386 static binaries are now build position
151 independend. This requires recompilation of all object
152 files used to create the crunched /rescue binary.
153 Clean the rescue directory in your obj directory before
154 doing an update build, otherwise linking will fail.
155
156 20180414:
157 Existing binutils was migrated to binutils.old. Manual
158 removal of tools/binutils objects directory may be required
159 to fix tools build failure.
160
161 20180311:
162 bdftopcf was updated and may need cleaning in the
163 src/external/mit/xorg/tools/bdftopcf subdirectory if there are
164 link errors.
165
166 20180212:
167 between OpenSSL and GCC updates, many things may fail to build.
168 any failure that looks like GCC or openssl is best handled by
169 a clean destdir and objdir. Full cleandir and destdir deletion
170 is recommended if build failures occur.
171
172 20171225:
173 removal of the vadvise syscall requires manual removal of all
174 associated files from the libc build object directory (including
175 the .depend files) - a command like:
176 cd $OBJ && find . -type d -name libc | xargs rm -rf
177 For architectures that support multiple "compat" binary targets,
178 you'll need to cleanup both the regular libc directory and the
179 compat ones (the above command will do that).
180
181 20171010:
182 a change to the build structure of external/bsd/acpica/bin/iasl
183 means that its objdir (or *.d and .depend at least) might need
184 to be manually removed - or a build done once without -u.
185
186 20170822:
187 a new version of GMP has been imported and probably
188 will break parts of builds related to themselves or GCC, both
189 in the tools and the native section. Remove all GCC, GMP, MPFR
190 and MPC objdirs or build once without -u.
191
192 20170816:
193 a new version of MPFR and MPC have been imported and probably
194 will break parts of builds related to themselves or GCC, both
195 in the tools and the native section. Remove all GCC, GMP, MPFR
196 and MPC objdirs or build once without -u.
197
198 20170402:
199 a new version of dhcpcd has been imported, which does not support
200 update builds from the previous version. Remove your
201 external/bsd/dhcpcd object dir or build once without -u.
202
203 20170211:
204 a new terminfo database has been imported.
205 The structure of it has changed slightly from prior versions and
206 an updated tic tool is required.
207 If you build.sh, don't use -u
208
209 20170207:
210 various arch dependent libc/exect.S files were removed
211 Either remove the obj directories (lib/libc and compat/amd64/i386/lib
212 if it exists) or do a clean build.
213 (This is a bug in the make system, it should be corrected without
214 human intervention, but isn't.)
215
216 20170104:
217 xinput build options have changed.
218 Remove the obj directory (external/mit/xorg/bin/xinput)
219 if you build.sh -u
220
221 20170103:
222 a new version of flex has been imported.
223 Remove the file from obj (external/bsd/flex)
224 if you build.sh -u
225
226 20161014:
227 a new version of OpenSSL has been imported.
228 Remove the files from obj (crypto/external/bsd/openssl)
229 if you build.sh -u
230
231 20161009:
232 a new version of dhcpcd has been imported with slightly changed
233 build infrastructure. When doing a build.sh -u this requires
234 pruning the external/bsd/dhcpcd objdir.
235
236 20160914:
237 i386, amd64, shark, ofppc and macppc have joined shark and x68k
238 ports in using xorg-server 1.18. This requires a clean destdir
239 and a clean objdir.
240
241 20160527:
242 i386 needs a full cleandir or objdir deletion because PIE has
243 been enabled. (see the amd64 entry two down for further info)
244
245 20160418:
246 libedit needs manual removal of all autogenerated files since
247 some of them are not autogenerated anymore. Remember that there
248 might be two copies of libedit if your platform builds "compat".
249
250 20160410:
251 amd64 needs full "make cleandir" or deletion of objdir now that
252 PIE has been enabled for amd64. PIE, or position-independent
253 executables, means all code, including executables and not just
254 shared libraries, is position-independent and hence able to be
255 relocated by ASLR, address space layout randomization.
256
257 The change was made in Makefile variables for compiler and
258 linker flags, for which make(1) does not record dependencies,
259 hence it is unable to detect that all .o files need rebuilding.
260
261 Partial rebuilds with some modified source files will likely
262 fail when linking executables, since the linker refuses to mix
263 position-independent code with position-dependent code in
264 position-independent executables:
265
266 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
267
268 20160401:
269 Ports switching to GCC 5.3 will need a full "make cleandir".
270 Some people have found that cleandir is not sufficient, so if
271 in doubt delete the entire object directory tree for gcc.
272
273 20160306:
274 NetBSD's regexp implementation is now part of libnbcompat.
275 Nblex, nbm4, nbpax, nbsed use it and they may crash on
276 non-NetBSD hosts if linked with stale object files produced
277 while they included a non-NetBSD regex.h.
278 In any case, you should "make cleandir" at least these tools
279 before updating your toolchain.
280
281 20160125:
282 Dtrace has been enabled by default on some architectures.
283 When doing an update build, make sure to clean the etc/mtree
284 object directory before starting the build - otherwise the
285 needed directories in destdir will not be created.
286 An easy way to do this is:
287 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
288
289 20150818:
290 New acpica requires "make cleandir" in src/external/bsd/acpica
291 again.
292
293 20150413:
294 New acpica requires "make cleandir" and reinstalling yacc
295 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
296 also "make cleandir" in /usr/src/external/bsd/acpica.
297
298 20150404:
299 Lint changes require a full rebuild of the tool, so make
300 sure to build without -u option to build.sh, or manually
301 do a make cleandir in src/tools/lint1 and
302 src/usr.bin/xlint.
303
304 20150310:
305 Improvements to openssl for arm mean that update builds of
306 the openssl libraries will fail. A make cleandir in
307 external/bsd/openssl/lib is needed
308
309 20141026:
310 A mishap during the import of pppd may cause your corruption
311 in your cvs directory if you happened to do a cvs update
312 during a short period of time. To fix, just remove the
313 directory src/external/bsd/ppp/dist/pppd completely
314 and let cvs restore it on next update.
315
316 20140721:
317 The src/external/mit/lua/src directory was accidentally created
318 and then deleted in the CVS repository. If you get errors like
319
320 cvs [update aborted]: cannot open directory
321 /cvsroot/src/external/mit/lua/src: No such file or directory
322
323 then delete your local copy of that directory tree and try again.
324
325 20140530:
326 ARM eABI switched to DWARF based exception handling. This requires
327 rebuilding all C++ code. It is strongly advised to do a clean build.
328
329 20140131:
330 The new compiler_rt/libc integration moved a few things. It is strongly
331 advised to do a clean build. At least lib/libc, the compat version(s)
332 of libc, libkern, rump and the kernels need to be cleaned.
333
334 20131227:
335 1. The new ntpd runs in a restricted mode to prevent amplification
336 attacks. If you need ntpdc to work you need to explicitly enable
337 mode7 in your config file. Make sure you put the necessary restrict
338 statements to avoid being exposed.
339 2. strncat has moved from lib/libc to common/lib/libc; you might need
340 to make clean in libc
341
342 20131129:
343 The GMP sources were updated, and builds will likely fail without
344 cleaning their build trees for both tools and in-tree, like below.
345
346 20131128:
347 The MPC and MPFR sources were updated, and builds may require their
348 tools and in-tree directories cleaned for successful updates.
349
350 20130605:
351 The kernel option FAST_IPSEC no longer exists, it's been renamed
352 to IPSEC (and the older IPSEC version removed).
353
354 20130605:
355 Previous freetype installations eroneously installed private
356 header files. If you are building against a non-empty $DESTDIR,
357 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
358
359 20130531:
360 The xdm update may cause build failure due to xdm.man being
361 in the obj tree. Make sure to ensure any like this:
362 nbmake: nbmake: don't know how to make xdm.man. Stop
363 is fixed by deleting the xdm.man in the obj tree.
364
365 20130530:
366 Updates of many xsrc packages will leave old .pc files around.
367 Best to clean out the xsrc objdir entirely before rebuilds.
368
369 20130301:
370 The removal of netiso requires manual removal of /usr/include/netiso
371 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
372
373 20120726:
374 The update of OpenSSL requires cleaning both the OpenSSL build
375 directory and DESTDIR. *Even non-update builds require cleaning
376 DESTDIR.* Builds done without taking these steps may fail, or in
377 some cases may succeed and install broken OpenSSL libraries that
378 cause third-party software to link incorrectly and/or crash.
379
380 20120507:
381 The database schema for makemandb was changed. You will
382 need to update the database using 'makemandb -f' or wait
383 for the next weekly run to fix it.
384
385 20120319:
386 sys/conf/Makefile.kern.inc has been modified to adjust the
387 size of db_symtab automatically. You need to update dbsym in
388 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
389 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
390 mk.conf.
391
392 20120216:
393 Default for MKCATPAGES changed to NO. Update builds will fail
394 unless DESTDIR is cleaned manually. If you built between 20120207
395 and 20120216, daily and weekly could have created an unreadable
396 /var/db/man.db index for apropos. Running makemandb -f or
397 the next run of weekly will fix it.
398
399 20111227:
400 If you built between 20111225 and 20111227 you need to remove
401 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
402 bump has been reverted.
403
404 20111125:
405 The "rnd" pseudodevice has been added to sys/conf/std, which
406 means it should no longer be explicitly listed in kernel
407 configuration files. The line "pseudo-device rnd" should be
408 removed from any custom kernel config files users may have.
409
410 20111119:
411 A problem with the datastructures used by the rndctl(8)
412 utility (pointers in datastructures in an array, making 32->64
413 bit compatibility very painful) has been fixed in a
414 non-backwards-compatible way. If you replace your kernel,
415 replace your rndctl executable too.
416
417 20111001:
418 the prop_*_send_syscall() functions from proplib(3) have been
419 changed and their new version is not backward compatible with the old
420 one. So ensure that all consumers of these functions (currently:
421 quota2 code and its tests) are updated together with the new lib.
422
423 20110817:
424 sparc has been changed to use GCC 4.5.3, so any objdir or
425 DESTDIR for them should be deleted before updating.
426
427 20110806:
428 i386 and amd64 have been changed to use GCC 4.5.3, so any
429 objdir or DESTDIR for them should be deleted before updating.
430
431 20110805:
432 The update to GCC 4.5.3 requires a non-trivial portion of
433 the tree to be cleaned. Best to delete both objdir and
434 DESTDIR before running this update. So far, only the
435 sparc64, mips and powerpc platforms have changed.
436
437 20110803:
438 The layout of external/public-domain/xz has changed. To do an
439 update build you will have to remove the contents of the OBJDIR
440 for external/public-domain/xz/bin by hand as the xz entry there
441 is now a directory.
442
443 20110410:
444 The configuration of src/tools/gcc has changed. To do an
445 update build you have to clean both tools/binutils and
446 tools/gcc by hand.
447
448 20110328:
449 Building the Xorg binary was moved into a subdirectory to fix
450 ordering issues with "make all". It may be necessary to remove
451 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
452 if your update build fails, as the "Xorg" entry there is now a
453 directory.
454
455 20110121:
456 Assembler files no longer use -traditional-cpp. This can break
457 the build of individual parts of the tree. This is handled
458 correctly by build.sh. Manual builds have to update /usr/share/mk
459 and re-run config(1) for any kernel configurations as needed.
460
461 20101217:
462 The tcpdump(8) program was changed to drop privileges and chroot(2)
463 by default. It may be necessary to manually update passwd(5) and
464 group(5) in order to make the program work with existing setups.
465
466 20101125:
467 The latest changes to setenv(3) dissallow setting environment
468 variables with names that contain '='. Revision 1.18 of env.c
469 assumed that this was allowed. Installing a new libc with an
470 old copy of /usr/bin/env causes env x=1 printenv | grep x= to
471 break which affects the autoconf tests for dependency finding,
472 so building gcc will end up printing:
473 checking dependency style of gcc... none
474 configure: error: no usable dependency style found
475 Fix it by rebuilding and re-installing env.
476
477 20101119:
478 Recent Xorg updates in xsrc/external/mit/ may cause various build
479 or run-time problems. Delete your entire DESTDIR and OBJDIR if you
480 have any build problems with xsrc, or problems with mismatched
481 versions between xorg-server and drivers.
482
483 20100604:
484 The update of ATF to 0.9 causes old tests written in shell to fail
485 unless they are rebuilt. If you are building with MKUPDATE=yes,
486 you need to clean the src/external/bsd/atf/tests/ and the src/tests/
487 trees by hand.
488
489 20100522:
490 Recent Xorg updates in xsrc/external/mit/ will cause various build
491 problems. Delete your entire DESTDIR and OBJDIR if you have any
492 build problems with xsrc.
493
494 20100522:
495 private section of <ctype.h> was splitted, and now mklocale(1)
496 include ctype_local.h, so you have to make cleandir in tools/mklocale.
497
498 20100520:
499 The location of the xkb compiled descriptions has changed. Please
500 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
501
502 20100222:
503 The shared objects file extension has been changed from .so to
504 .pico, in order to avoid conflicts with shared libraries names
505 libXX.so. All now stale regular .so files can be removed from
506 your object directories.
507
508 20100204:
509 The termcap database has been removed from the sources,
510 but has not been marked obsolete so it is not removed
511 from the system when upgrading.
512 As such, you will need to remove them from your object
513 and destination directories.
514
515 20091101:
516 After updating, it may be necessary to make the 'cleandir'
517 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
518 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
519 src/tools/lex/ and src/usr.bin/lex/.
520
521 20091001:
522 On amd64 you must rebuild tools (to get the new binutils)
523 before building a kernel, or the build fails on cpufunc.S.
524
525 20091001:
526 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
527 symlink, failing the build. Delete the link, and the subdir
528 it is in, and retry your build.
529
530 20090718:
531 libc build changed so that strchr() provides the extra entry
532 point for index(). Update build of libc.a (and libc_pic.a)
533 may fail because the archive contains the unwanted index.o.
534 (Similarly for strrchr() and rindex().)
535
536 20090709:
537 Native Xorg was upgraded again. Builds will probably fail again
538 without a clean objdir, at least for src/external/mit/xorg.
539
540 20090616:
541 Native Xorg was upgraded. Builds will need a clean objdir for
542 src/external/mit/xorg. Upgrading a system from sets will not
543 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
544 subdirectory has been changed into a file, and this needs to
545 be manually "rm -r"'ed before installing xbase.tgz.
546
547 20090501:
548 Several new functions were added to string.h/libc, and this
549 can cause autoconf problems during the tool build for people
550 who fail to clean out their tools objects properly. If you
551 note messages about stpcpy, stpncpy or strnlen accompanying a
552 failure during the tool build, clean out all your tools
553 objects and start again.
554
555 20090325:
556 The i386 port was switched to i486 default toolchain. This requires
557 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
558
559 20090126:
560 The __posix_fadvise50 system call changed assembly stub type. You
561 need to 'rm -f __posix_fadvise50.*' in the libc build directory
562 to avoid using the old assembly stub.
563
564 20090202:
565 pkg_install now depends on the pkgdb cache for automatic conflict
566 detection. It is recommented to rebuild the cache with
567 ``pkg_admin rebuild''.
568
569 20090110:
570 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
571 1. Make sure your kernel has COMPAT_50 in it. Build and install.
572 This is needed even in the MODULAR kernel because there is
573 conditionally compiled code in rtsock.c.
574 2. make sure build.sh completes and the binaries in a chroot work
575 before installing.
576 3. If you don't use build.sh and you build directly to root, and
577 your build breaks in the middle, don't despair. Make sure headers
578 are installed properly, and start building libraries first libc
579 and libutil, install them and then continue building all the
580 libraries in src/lib and src/gnu/lib and install them. Once
581 the new libraries are installed, you can restart the build.
582 4. If you compile packages and you notice link time warnings,
583 rebuild the required packages to update their shared libraries.
584 Any package you rebuild will require rebuilding all the packages
585 that depend on it.
586 5. Next time you run pwd_mkdb with the new binary, the file
587 will be upgraded and it will not be backwards compatible.
588 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
589 lastlogx(5)) have been versioned, and there is a heuristic
590 for utmp. You are better off removing the old files after
591 upgrading. The automated clearing of /var/run during
592 boot, and the automated rotating of files in /var/log by
593 newsyslog(8), may mean that you do not have to remove the
594 files manually.
595 7. The optional accounting file (/var/account/acct, see
596 accton(8)) has not been versioned, and will need to be
597 removed. The automatic rotation of the accounting file by
598 /etc/daily limits the bad consequences of failure to remove
599 the file.
600 8. Application software that writes time_t to binary files on
601 disk will break or need attention. Most notably: if you are
602 using PostgreSQL < 8.4, you need to dump your databases,
603 rebuild PostgreSQL with the new time_t, then restore.
604
605 20081219:
606 config(1) has been updated, and one of the files it creates -
607 swapnetbsd.o - has changed format. You need to rebuild config
608 (done automatically by build.sh) and then you need to rerun
609 config on all kernel configuration files before rebuilding those
610 kernels.
611
612 20081205:
613 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
614 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
615 set and will appear as extra files for MKX11=no update builds.
616
617 20081122:
618 On i386, various kernel options(4) in GENERIC including
619 file systems have been disabled and moved into kernel modules.
620 Before trying a new GENERIC kernel, you have to prepare the
621 following files as well as a new GENERIC kernel:
622
623 - build and install kernel modules from src/sys/modules
624
625 - install the latest bootloader, which will load a module
626 for the file system from which the kernel is loaded automatically
627
628 If you have to load your kernel from a file system which is not of
629 the same type as the root file system, you have to load the necessary
630 file system module manually on the boot prompt or in the boot.cfg file.
631
632 20080827:
633 If you built and installed a libc from sources between
634 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
635 which results in false errors reported by lint(1).
636 Since this breaks the libc build itself, manual help is
637 needed -- lint must be disabled temporarily, e.g.:
638 $ (cd lib/libc && make MKLINT=no dependall install)
639
640 20080813:
641 MKDEBUG build was broken because the .depend files did not know
642 about .go files. You need to remove all .depend files and rebuild.
643
644 20080802:
645 A regression in binary compatibility for pthread_mutex_t has
646 been fixed. Unfortunately, the price is breaking compatibility
647 for -current.
648
649 Threaded programs (using libpthread) and C++ programs (using
650 libstdc++) compiled after 20070907 and before 20080802 need to
651 be recompiled.
652
653 One way to find affected pkgsrc packages:
654
655 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
656 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
657
658 20080731:
659 WAPBL (metadata journaling support) has been added, but at this
660 time isn't backwards compatible with pre-WAPBL aware kernels
661 and userland (fsck_ffs in particular). Please make sure you
662 don't use a journaled filesystem with an older kernel/userland,
663 especially an uncleanly mounted journaled filesystem. WAPBL
664 also requires the super block to be in the UFS2 format. You
665 can use fsck_ffs -c 4 to update the superblock format.
666
667 20080721:
668 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
669 isn't defined.
670
671 20080531:
672 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
673 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
674 utility needs to be rebuilt and reinstalled as older binaries
675 won't work correctly. The following sequence of commands:
676
677 $ (cd sys/sys/ && nbmake-$arch includes)
678 $ (cd sbin/drvctl/ && nbmake-$arch clean)
679 $ (cd sbin/drvctl/ && nbmake-$arch all)
680
681 leaves new drvctl utility in sbin/drvctl build directory.
682
683 20080503:
684 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
685
686 20080521:
687 For a while, unprivileged UPDATE builds would fail to
688 succeed at the checkflist stage, complaining that
689 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
690 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
691 If you already hit this problem, update the .mk file,
692 remove ${DESTDIR}/stand/<arch>, and re-run the build.
693
694 20080303:
695 Linker warnings are now fatal if $WARNS>0.
696
697 20080126:
698 The posix_fadvise system call has been changed from an assembly
699 stub, to a c file that calls an assembly stub. You need to
700 'rm -f posix_fadvise.* .depend' in the libc build directory to
701 avoid using the old assembly stub.
702
703 20071209:
704 The acpiec(4) driver has been split into two attachments. If you
705 get ACPI errors before the attachment, please update your kernel
706 configuration file appropriately or see GENERIC for more details.
707
708 20071115:
709 The it(4) driver has been renamed to itesio(4) and the old port
710 argument specified in the kernel configuration file is not valid
711 anymore. The itesio(4) driver now uses the Super I/O address port
712 rather than the EC address port. Please update your kernel
713 configuration file appropriately or see GENERIC for more details.
714
715 20071028:
716 The pccons(4) driver has been removed from the NetBSD/shark port.
717 You need to update any custom kernel configuration file you have
718 to remove any references to pccons (which includes removing the
719 now useless XSERVER option) and replace them with the correct
720 entries for the wscons driver. See the GENERIC configuration file
721 for more details.
722
723 20070913:
724 A latent bug in dhclient/dhcpd that caused it to be unable to
725 enumerate interfaces was fixed. The bug began to cause
726 problems after 20070911 when the kernel's SIOCGIFCONF
727 implementation was repaired. From 20070529 to 20070911 racoon
728 could not enumerate interfaces. (These are noted because
729 normal kernel/userspace version matching hygiene is not
730 sufficient to avoid this problem.) Ensure that both kernel
731 and userland are from after 20070913.
732
733 20070703:
734 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
735 calls the target-specific strip program, and the logic to pass
736 down STRIP from make has been removed. This requires a
737 re-installation of tools.
738
739 20070422:
740 The way OS emulations lookup filenames inside the emulation root
741 has been changed. Rather than modify the pathname (and copy back
742 to userspace) namei() and lookup() directly check the emulation
743 root. One side effect is that absolute symlinks inside the emulated
744 root file system will be relative to that file system - unless they
745 start /../ this is useful when the emulated root is a real install
746 that has such links.
747 This might affect symlinks that have been added to reference outside
748 the emulated root.
749
750 20070412:
751 The pckbc driver on sgimips IP32 has been removed. Use macekbc
752 instead. See the GENERIC32_IP3x kernel configuration for an
753 example.
754
755 20070319:
756 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
757 on many platforms due to incorrect flags settings. If you
758 updated and built after about 20070315, do "nbmake-$arch
759 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
760 rebuild of object files that might have been built
761 incorrectly, and ensure that you have at least
762 src/lib/libc/Makefile 1.130.
763
764 20070210:
765 src/sys/sys/{sa.h,savar.h} were removed.
766 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
767 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
768 will allow dependencies on those files to get get rebuilt
769
770 20070209:
771 The threading model was changed when the newlock2 branch
772 was merged to NetBSD-current. If you boot with a new
773 kernel (version 4.99.10), then you also need a new pthread
774 library (/usr/lib/libpthread.so.0.7). If you boot with
775 an old kernel, then you need the old pthread library
776 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
777 the pthread library in sync, old threaded applications should
778 continue to work with an old or new kernel. Note that named(8)
779 is the only threaded application in the base system.
780
781 20061214:
782 Following the move of string_to_flags() and flags_to_string()
783 from the bin/ls/ sources to libutil, users doing UPDATE builds
784 will need to do a "make cleandir" in
785 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
786 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
787 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
788 as the installation images in distrib/
789 in order to excise stale references to the old stat_flags.h header
790 file in the ls sources -- stat_flags.h has been removed.
791
792 20061108:
793 The configure script used in the src/tools/gcc compiler has been
794 changed to indicate that our libc has ssp support built-in and
795 does not depend on -lssp and -lssp-nonshared. You'll need to
796 make clean in src/tools/gcc first to rebuild the compiler.
797
798 20061009:
799 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
800 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
801
802 20060814:
803 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
804 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
805 kernel configuration for an example. X servers from the last
806 few years should cope.
807
808 20060703:
809 MPACPI is no more. We always configure PCI interrupts using ACPI
810 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
811 to ACPI_SCANPCI. Thanks to work from fvdl.
812
813 20060627:
814 socket(2) has changed, and its system call has been versioned.
815 For userlands with the old version of socket(2), make sure that
816 your kernel has 'options COMPAT_30' set, or else 'bad system call'
817 errors will result.
818
819 Hints for a more successful build:
820 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
821 Use build.sh, but do not use its "expert mode":
822 This will automatically build the tools in the
823 correct order, and it will keep the tools and the
824 new build products from interfering with the running
825 system. This will allow you to ignore most of the
826 other advice in this file.
827 Build a new kernel first:
828 This makes sure that any new system calls or features
829 expected by the new userland will be present. This
830 helps to avoid critical errors when upgrading.
831 Use object directories:
832 This helps to keep stale object
833 files from polluting the build if a Makefile "forgets"
834 about one. It also makes it easier to clean up after
835 a build. It's also necessary if you want to use the
836 same source tree for multiple machines.
837 To use object directories with build.sh:
838 a) invoke build.sh with the "-M" or "-O" options.
839 To use object directories without using build.sh:
840 a) cd /usr/src ; make cleandir
841 b) Add "OBJMACHINE=yes" to /etc/mk.conf
842 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
843 d) cd /usr/src ; make build
844 Note that running "make obj" in a directory will create
845 in obj.$MACHINE directory.
846 Build to a DESTDIR:
847 This helps to keep old installed files (especially libraries)
848 from interfering with the new build.
849 To build to a DESTDIR with build.sh, use the "-D" option.
850 To build to a DESTDIR without using build.sh, set the DESTDIR
851 environment variable before running make build. It should be
852 set to the pathname of an initially empty directory.
853 Problems: if you do not use build.sh, you might need to
854 update critical utilities without using DESTDIR since
855 nothing is executed from what is installed in DESTDIR.
856 (See critical utils, below.)
857 Build often:
858 This keeps critical utilities current enough to not choke
859 on any other part of the source tree that depends on up to
860 date functionality. If you use build.sh, you should not have
861 this problem.
862
863 What to do if things don't work:
864 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
865 When things don't work there are usually a few things that commonly
866 should be done.
867 1) make includes
868 This should be done automatically by make build.
869 2) cd share/mk && make install
870 Again, automatically done by make build.
871
872 Failsafe rebuild of a small part of the tree:
873 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
874 To make sure you rebuild something correctly you want to do
875 something like the following:
876 1) Make sure the includes and .mk files are up to date.
877 2) Make sure any program used to build the particular
878 utility is up to date. (yacc, lex, etc...)
879 3) cd ...path/to/util...
880 make cleandir
881 rm ...all obj directories...
882 make cleandir # yes, again
883 make obj
884 make depend && make
885
886 Failsafe rebuild of the entire tree:
887 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
888 If you really want to make sure the source tree is clean and
889 ready for a build try the following. Note that sourcing /etc/mk.conf
890 (a make(1) Makefile) in this manner is not right, and will not work
891 for anyone who uses any make(1) features in /etc/mk.conf.
892

925
926 Other problems and possible solutions:
927 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
928 Symptom:Complaints involving a Makefile.
929 Fix: Rebuild usr.bin/make:
930 cd usr.bin/make && make && make install
931 Or, a failsafe method if that doesn't work:
932 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
933
934 Fix: Make sure .mk files are up to date.
935 cd share/mk && make install
936
937 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
938 Fix: Rebuild usr.bin/config
939
940 Symptom:
941 Fix: Rebuild usr.bin/yacc
942
943 Symptom:
944 Fix: Rebuild usr.bin/lex
945
946 Symptom:
947 Fix: rm /usr/lib/libbfd.a
948
949 Symptom:Obsolete intermediate files are used during compilation
950 Fix: Try the following sequence of commands in the directory in question.
951 make cleandir; rm `make print-objdir`; make cleandir; make obj
952 (If you built the tree without "make obj" in the past, obsolete files
953 may remain. The command tries to clean everything up)
954
955 Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible
956 pointer type
957 Fix: Rebuild and install usr.bin/menuc
958
959 Symptom:mklocale not found during build in share/locale/ctype
960 Fix: Build and install usr.bin/mklocale
961
962 Symptom:undefined reference to `__assert13' or `__unsetenv13'
963 Fix: Rebuild and install lib/libc
964
965 Symptom:usr.bin/config fails to build.
966 Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
967
968 Symptom:undefined reference to `getprogname' or `setprogname'
969 Fix: Rebuild and install lib/libc
970
971 Symptom:lint does not understand the '-X' option
972 Fix: May need to build & install libs with NOLINT=1 before rebuilding lint
973
974 Symptom:Update build fails in src/tools/gcc complaining that a variable
975 (e.g. CPPFLAGS) has changed since the previous run.
976 Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
977
978 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
979 No such file or directory.
980 Cause: If a directory is created by mistake, then it is sometimes
981 deleted from the CVS repository using administrative commands
982 that bypass the normal cvs access controls. If your cvs working tree
983 contains references to a directory that has been deleted on the
984 server in this way, then "cvs update" reports this error.
985 Fix: Recursively delete the affected directory from your working tree
986 and try the update again.
987
