UPDATING revision 1.305 1 $NetBSD: UPDATING,v 1.305 2019/11/13 09:59:02 martin 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 20191112:
23 The LLVM update requires a clean rebuild for all architectures using
24 LLVM during the tools build phase (i386, amd64, aarch64).
25
26 20191022:
27 Ports amd64 and aarch64 switched to GCC 8.3 by default.
28 In-place ("expert mode", build.sh -E) builds are not supported
29 when going from a GCC 7 userland to GCC 8. Do a regular
30 build to a different DESTDIR (or preferably: build.sh -U) at least
31 once and install sets, or download compt.{tar.xz,tgz} from the
32 daily builds and install that before doing the next in-place build.
33
34 20191001:
35
36 GCC 8.3 was imported. Builds of src/tools/gcc may fail if
37 old builds with GCC 7 output now uses GCC 8. Clean this
38 directory, and also clean src/external/gpl3/gcc.
39
40 20190903:
41
42 File with names that coincide with existing files' names on
43 case-insensitive file systems were inadvertently committed, for
44 radeon GPU firmware. We cannot mark these as obsolete for
45 postinstall to fix, so if you updated src since 2019-08-26, and
46 ran build.sh distribution or ran build.sh release, you must
47 manually delete the following files in your DESTDIR (which is
48 usually $OBJDIR/destir.$ARCH), or from / if you have installed
49 them:

118 We will re-import these radeon firmware images another way
119 later.
120
121 20190727:
122 The uefi bootloader has gained tftp support and needs a clean
123 build. If you do update builds, manually clean its object
124 directory by something like:
125 cd sys/arch/i386/stand/efiboot && make clean
126
127 20190723:
128 The jemalloc allocator in libc is now build without extended
129 debugging (for performance reasons). In update builds make sure
130 to rebuild it completly, by removing all affected object files,
131 including compat builds, something like:
132 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
133
134 20190207:
135 GCC 7 switched for many ports. Update builds are likely to fail.
136
137 20180924:
138 A newer OpenSSL version has been imported. If you are doing
139 update builds, make sure to remove all old obj dirs, like:
140 cd /usr/obj && find . -type d -name openssl | xargs rm -rf
141
142 20180717:
143 On aarch64 int64_t and related types have changed from long long
144 to long. This requires recompiling all C++ binaries.
145
146 20180713:
147 On amd64 and i386 static binaries are now build position
148 independend. This requires recompilation of all object
149 files used to create the crunched /rescue binary.
150 Clean the rescue directory in your obj directory before
151 doing an update build, otherwise linking will fail.
152
153 20180414:
154 Existing binutils was migrated to binutils.old. Manual
155 removal of tools/binutils objects directory may be required
156 to fix tools build failure.
157
158 20180311:
159 bdftopcf was updated and may need cleaning in the
160 src/external/mit/xorg/tools/bdftopcf subdirectory if there are
161 link errors.
162
163 20180212:
164 between OpenSSL and GCC updates, many things may fail to build.
165 any failure that looks like GCC or openssl is best handled by
166 a clean destdir and objdir. Full cleandir and destdir deletion
167 is recommended if build failures occur.
168
169 20171225:
170 removal of the vadvise syscall requires manual removal of all
171 associated files from the libc build object directory (including
172 the .depend files) - a command like:
173 cd $OBJ && find . -type d -name libc | xargs rm -rf
174 For architectures that support multiple "compat" binary targets,
175 you'll need to cleanup both the regular libc directory and the
176 compat ones (the above command will do that).
177
178 20171010:
179 a change to the build structure of external/bsd/acpica/bin/iasl
180 means that its objdir (or *.d and .depend at least) might need
181 to be manually removed - or a build done once without -u.
182
183 20170822:
184 a new version of GMP has been imported and probably
185 will break parts of builds related to themselves or GCC, both
186 in the tools and the native section. Remove all GCC, GMP, MPFR
187 and MPC objdirs or build once without -u.
188
189 20170816:
190 a new version of MPFR and MPC have been imported and probably
191 will break parts of builds related to themselves or GCC, both
192 in the tools and the native section. Remove all GCC, GMP, MPFR
193 and MPC objdirs or build once without -u.
194
195 20170402:
196 a new version of dhcpcd has been imported, which does not support
197 update builds from the previous version. Remove your
198 external/bsd/dhcpcd object dir or build once without -u.
199
200 20170211:
201 a new terminfo database has been imported.
202 The structure of it has changed slightly from prior versions and
203 an updated tic tool is required.
204 If you build.sh, don't use -u
205
206 20170207:
207 various arch dependent libc/exect.S files were removed
208 Either remove the obj directories (lib/libc and compat/amd64/i386/lib
209 if it exists) or do a clean build.
210 (This is a bug in the make system, it should be corrected without
211 human intervention, but isn't.)
212
213 20170104:
214 xinput build options have changed.
215 Remove the obj directory (external/mit/xorg/bin/xinput)
216 if you build.sh -u
217
218 20170103:
219 a new version of flex has been imported.
220 Remove the file from obj (external/bsd/flex)
221 if you build.sh -u
222
223 20161014:
224 a new version of OpenSSL has been imported.
225 Remove the files from obj (crypto/external/bsd/openssl)
226 if you build.sh -u
227
228 20161009:
229 a new version of dhcpcd has been imported with slightly changed
230 build infrastructure. When doing a build.sh -u this requires
231 pruning the external/bsd/dhcpcd objdir.
232
233 20160914:
234 i386, amd64, shark, ofppc and macppc have joined shark and x68k
235 ports in using xorg-server 1.18. This requires a clean destdir
236 and a clean objdir.
237
238 20160527:
239 i386 needs a full cleandir or objdir deletion because PIE has
240 been enabled. (see the amd64 entry two down for further info)
241
242 20160418:
243 libedit needs manual removal of all autogenerated files since
244 some of them are not autogenerated anymore. Remember that there
245 might be two copies of libedit if your platform builds "compat".
246
247 20160410:
248 amd64 needs full "make cleandir" or deletion of objdir now that
249 PIE has been enabled for amd64. PIE, or position-independent
250 executables, means all code, including executables and not just
251 shared libraries, is position-independent and hence able to be
252 relocated by ASLR, address space layout randomization.
253
254 The change was made in Makefile variables for compiler and
255 linker flags, for which make(1) does not record dependencies,
256 hence it is unable to detect that all .o files need rebuilding.
257
258 Partial rebuilds with some modified source files will likely
259 fail when linking executables, since the linker refuses to mix
260 position-independent code with position-dependent code in
261 position-independent executables:
262
263 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
264
265 20160401:
266 Ports switching to GCC 5.3 will need a full "make cleandir".
267 Some people have found that cleandir is not sufficient, so if
268 in doubt delete the entire object directory tree for gcc.
269
270 20160306:
271 NetBSD's regexp implementation is now part of libnbcompat.
272 Nblex, nbm4, nbpax, nbsed use it and they may crash on
273 non-NetBSD hosts if linked with stale object files produced
274 while they included a non-NetBSD regex.h.
275 In any case, you should "make cleandir" at least these tools
276 before updating your toolchain.
277
278 20160125:
279 Dtrace has been enabled by default on some architectures.
280 When doing an update build, make sure to clean the etc/mtree
281 object directory before starting the build - otherwise the
282 needed directories in destdir will not be created.
283 An easy way to do this is:
284 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
285
286 20150818:
287 New acpica requires "make cleandir" in src/external/bsd/acpica
288 again.
289
290 20150413:
291 New acpica requires "make cleandir" and reinstalling yacc
292 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
293 also "make cleandir" in /usr/src/external/bsd/acpica.
294
295 20150404:
296 Lint changes require a full rebuild of the tool, so make
297 sure to build without -u option to build.sh, or manually
298 do a make cleandir in src/tools/lint1 and
299 src/usr.bin/xlint.
300
301 20150310:
302 Improvements to openssl for arm mean that update builds of
303 the openssl libraries will fail. A make cleandir in
304 external/bsd/openssl/lib is needed
305
306 20141026:
307 A mishap during the import of pppd may cause your corruption
308 in your cvs directory if you happened to do a cvs update
309 during a short period of time. To fix, just remove the
310 directory src/external/bsd/ppp/dist/pppd completely
311 and let cvs restore it on next update.
312
313 20140721:
314 The src/external/mit/lua/src directory was accidentally created
315 and then deleted in the CVS repository. If you get errors like
316
317 cvs [update aborted]: cannot open directory
318 /cvsroot/src/external/mit/lua/src: No such file or directory
319
320 then delete your local copy of that directory tree and try again.
321
322 20140530:
323 ARM eABI switched to DWARF based exception handling. This requires
324 rebuilding all C++ code. It is strongly advised to do a clean build.
325
326 20140131:
327 The new compiler_rt/libc integration moved a few things. It is strongly
328 advised to do a clean build. At least lib/libc, the compat version(s)
329 of libc, libkern, rump and the kernels need to be cleaned.
330
331 20131227:
332 1. The new ntpd runs in a restricted mode to prevent amplification
333 attacks. If you need ntpdc to work you need to explicitly enable
334 mode7 in your config file. Make sure you put the necessary restrict
335 statements to avoid being exposed.
336 2. strncat has moved from lib/libc to common/lib/libc; you might need
337 to make clean in libc
338
339 20131129:
340 The GMP sources were updated, and builds will likely fail without
341 cleaning their build trees for both tools and in-tree, like below.
342
343 20131128:
344 The MPC and MPFR sources were updated, and builds may require their
345 tools and in-tree directories cleaned for successful updates.
346
347 20130605:
348 The kernel option FAST_IPSEC no longer exists, it's been renamed
349 to IPSEC (and the older IPSEC version removed).
350
351 20130605:
352 Previous freetype installations eroneously installed private
353 header files. If you are building against a non-empty $DESTDIR,
354 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
355
356 20130531:
357 The xdm update may cause build failure due to xdm.man being
358 in the obj tree. Make sure to ensure any like this:
359 nbmake: nbmake: don't know how to make xdm.man. Stop
360 is fixed by deleting the xdm.man in the obj tree.
361
362 20130530:
363 Updates of many xsrc packages will leave old .pc files around.
364 Best to clean out the xsrc objdir entirely before rebuilds.
365
366 20130301:
367 The removal of netiso requires manual removal of /usr/include/netiso
368 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
369
370 20120726:
371 The update of OpenSSL requires cleaning both the OpenSSL build
372 directory and DESTDIR. *Even non-update builds require cleaning
373 DESTDIR.* Builds done without taking these steps may fail, or in
374 some cases may succeed and install broken OpenSSL libraries that
375 cause third-party software to link incorrectly and/or crash.
376
377 20120507:
378 The database schema for makemandb was changed. You will
379 need to update the database using 'makemandb -f' or wait
380 for the next weekly run to fix it.
381
382 20120319:
383 sys/conf/Makefile.kern.inc has been modified to adjust the
384 size of db_symtab automatically. You need to update dbsym in
385 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
386 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
387 mk.conf.
388
389 20120216:
390 Default for MKCATPAGES changed to NO. Update builds will fail
391 unless DESTDIR is cleaned manually. If you built between 20120207
392 and 20120216, daily and weekly could have created an unreadable
393 /var/db/man.db index for apropos. Running makemandb -f or
394 the next run of weekly will fix it.
395
396 20111227:
397 If you built between 20111225 and 20111227 you need to remove
398 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
399 bump has been reverted.
400
401 20111125:
402 The "rnd" pseudodevice has been added to sys/conf/std, which
403 means it should no longer be explicitly listed in kernel
404 configuration files. The line "pseudo-device rnd" should be
405 removed from any custom kernel config files users may have.
406
407 20111119:
408 A problem with the datastructures used by the rndctl(8)
409 utility (pointers in datastructures in an array, making 32->64
410 bit compatibility very painful) has been fixed in a
411 non-backwards-compatible way. If you replace your kernel,
412 replace your rndctl executable too.
413
414 20111001:
415 the prop_*_send_syscall() functions from proplib(3) have been
416 changed and their new version is not backward compatible with the old
417 one. So ensure that all consumers of these functions (currently:
418 quota2 code and its tests) are updated together with the new lib.
419
420 20110817:
421 sparc has been changed to use GCC 4.5.3, so any objdir or
422 DESTDIR for them should be deleted before updating.
423
424 20110806:
425 i386 and amd64 have been changed to use GCC 4.5.3, so any
426 objdir or DESTDIR for them should be deleted before updating.
427
428 20110805:
429 The update to GCC 4.5.3 requires a non-trivial portion of
430 the tree to be cleaned. Best to delete both objdir and
431 DESTDIR before running this update. So far, only the
432 sparc64, mips and powerpc platforms have changed.
433
434 20110803:
435 The layout of external/public-domain/xz has changed. To do an
436 update build you will have to remove the contents of the OBJDIR
437 for external/public-domain/xz/bin by hand as the xz entry there
438 is now a directory.
439
440 20110410:
441 The configuration of src/tools/gcc has changed. To do an
442 update build you have to clean both tools/binutils and
443 tools/gcc by hand.
444
445 20110328:
446 Building the Xorg binary was moved into a subdirectory to fix
447 ordering issues with "make all". It may be necessary to remove
448 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
449 if your update build fails, as the "Xorg" entry there is now a
450 directory.
451
452 20110121:
453 Assembler files no longer use -traditional-cpp. This can break
454 the build of individual parts of the tree. This is handled
455 correctly by build.sh. Manual builds have to update /usr/share/mk
456 and re-run config(1) for any kernel configurations as needed.
457
458 20101217:
459 The tcpdump(8) program was changed to drop privileges and chroot(2)
460 by default. It may be necessary to manually update passwd(5) and
461 group(5) in order to make the program work with existing setups.
462
463 20101125:
464 The latest changes to setenv(3) dissallow setting environment
465 variables with names that contain '='. Revision 1.18 of env.c
466 assumed that this was allowed. Installing a new libc with an
467 old copy of /usr/bin/env causes env x=1 printenv | grep x= to
468 break which affects the autoconf tests for dependency finding,
469 so building gcc will end up printing:
470 checking dependency style of gcc... none
471 configure: error: no usable dependency style found
472 Fix it by rebuilding and re-installing env.
473
474 20101119:
475 Recent Xorg updates in xsrc/external/mit/ may cause various build
476 or run-time problems. Delete your entire DESTDIR and OBJDIR if you
477 have any build problems with xsrc, or problems with mismatched
478 versions between xorg-server and drivers.
479
480 20100604:
481 The update of ATF to 0.9 causes old tests written in shell to fail
482 unless they are rebuilt. If you are building with MKUPDATE=yes,
483 you need to clean the src/external/bsd/atf/tests/ and the src/tests/
484 trees by hand.
485
486 20100522:
487 Recent Xorg updates in xsrc/external/mit/ will cause various build
488 problems. Delete your entire DESTDIR and OBJDIR if you have any
489 build problems with xsrc.
490
491 20100522:
492 private section of <ctype.h> was splitted, and now mklocale(1)
493 include ctype_local.h, so you have to make cleandir in tools/mklocale.
494
495 20100520:
496 The location of the xkb compiled descriptions has changed. Please
497 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
498
499 20100222:
500 The shared objects file extension has been changed from .so to
501 .pico, in order to avoid conflicts with shared libraries names
502 libXX.so. All now stale regular .so files can be removed from
503 your object directories.
504
505 20100204:
506 The termcap database has been removed from the sources,
507 but has not been marked obsolete so it is not removed
508 from the system when upgrading.
509 As such, you will need to remove them from your object
510 and destination directories.
511
512 20091101:
513 After updating, it may be necessary to make the 'cleandir'
514 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
515 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
516 src/tools/lex/ and src/usr.bin/lex/.
517
518 20091001:
519 On amd64 you must rebuild tools (to get the new binutils)
520 before building a kernel, or the build fails on cpufunc.S.
521
522 20091001:
523 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
524 symlink, failing the build. Delete the link, and the subdir
525 it is in, and retry your build.
526
527 20090718:
528 libc build changed so that strchr() provides the extra entry
529 point for index(). Update build of libc.a (and libc_pic.a)
530 may fail because the archive contains the unwanted index.o.
531 (Similarly for strrchr() and rindex().)
532
533 20090709:
534 Native Xorg was upgraded again. Builds will probably fail again
535 without a clean objdir, at least for src/external/mit/xorg.
536
537 20090616:
538 Native Xorg was upgraded. Builds will need a clean objdir for
539 src/external/mit/xorg. Upgrading a system from sets will not
540 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
541 subdirectory has been changed into a file, and this needs to
542 be manually "rm -r"'ed before installing xbase.tgz.
543
544 20090501:
545 Several new functions were added to string.h/libc, and this
546 can cause autoconf problems during the tool build for people
547 who fail to clean out their tools objects properly. If you
548 note messages about stpcpy, stpncpy or strnlen accompanying a
549 failure during the tool build, clean out all your tools
550 objects and start again.
551
552 20090325:
553 The i386 port was switched to i486 default toolchain. This requires
554 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
555
556 20090126:
557 The __posix_fadvise50 system call changed assembly stub type. You
558 need to 'rm -f __posix_fadvise50.*' in the libc build directory
559 to avoid using the old assembly stub.
560
561 20090202:
562 pkg_install now depends on the pkgdb cache for automatic conflict
563 detection. It is recommented to rebuild the cache with
564 ``pkg_admin rebuild''.
565
566 20090110:
567 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
568 1. Make sure your kernel has COMPAT_50 in it. Build and install.
569 This is needed even in the MODULAR kernel because there is
570 conditionally compiled code in rtsock.c.
571 2. make sure build.sh completes and the binaries in a chroot work
572 before installing.
573 3. If you don't use build.sh and you build directly to root, and
574 your build breaks in the middle, don't despair. Make sure headers
575 are installed properly, and start building libraries first libc
576 and libutil, install them and then continue building all the
577 libraries in src/lib and src/gnu/lib and install them. Once
578 the new libraries are installed, you can restart the build.
579 4. If you compile packages and you notice link time warnings,
580 rebuild the required packages to update their shared libraries.
581 Any package you rebuild will require rebuilding all the packages
582 that depend on it.
583 5. Next time you run pwd_mkdb with the new binary, the file
584 will be upgraded and it will not be backwards compatible.
585 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
586 lastlogx(5)) have been versioned, and there is a heuristic
587 for utmp. You are better off removing the old files after
588 upgrading. The automated clearing of /var/run during
589 boot, and the automated rotating of files in /var/log by
590 newsyslog(8), may mean that you do not have to remove the
591 files manually.
592 7. The optional accounting file (/var/account/acct, see
593 accton(8)) has not been versioned, and will need to be
594 removed. The automatic rotation of the accounting file by
595 /etc/daily limits the bad consequences of failure to remove
596 the file.
597 8. Application software that writes time_t to binary files on
598 disk will break or need attention. Most notably: if you are
599 using PostgreSQL < 8.4, you need to dump your databases,
600 rebuild PostgreSQL with the new time_t, then restore.
601
602 20081219:
603 config(1) has been updated, and one of the files it creates -
604 swapnetbsd.o - has changed format. You need to rebuild config
605 (done automatically by build.sh) and then you need to rerun
606 config on all kernel configuration files before rebuilding those
607 kernels.
608
609 20081205:
610 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
611 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
612 set and will appear as extra files for MKX11=no update builds.
613
614 20081122:
615 On i386, various kernel options(4) in GENERIC including
616 file systems have been disabled and moved into kernel modules.
617 Before trying a new GENERIC kernel, you have to prepare the
618 following files as well as a new GENERIC kernel:
619
620 - build and install kernel modules from src/sys/modules
621
622 - install the latest bootloader, which will load a module
623 for the file system from which the kernel is loaded automatically
624
625 If you have to load your kernel from a file system which is not of
626 the same type as the root file system, you have to load the necessary
627 file system module manually on the boot prompt or in the boot.cfg file.
628
629 20080827:
630 If you built and installed a libc from sources between
631 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
632 which results in false errors reported by lint(1).
633 Since this breaks the libc build itself, manual help is
634 needed -- lint must be disabled temporarily, e.g.:
635 $ (cd lib/libc && make MKLINT=no dependall install)
636
637 20080813:
638 MKDEBUG build was broken because the .depend files did not know
639 about .go files. You need to remove all .depend files and rebuild.
640
641 20080802:
642 A regression in binary compatibility for pthread_mutex_t has
643 been fixed. Unfortunately, the price is breaking compatibility
644 for -current.
645
646 Threaded programs (using libpthread) and C++ programs (using
647 libstdc++) compiled after 20070907 and before 20080802 need to
648 be recompiled.
649
650 One way to find affected pkgsrc packages:
651
652 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
653 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
654
655 20080731:
656 WAPBL (metadata journaling support) has been added, but at this
657 time isn't backwards compatible with pre-WAPBL aware kernels
658 and userland (fsck_ffs in particular). Please make sure you
659 don't use a journaled filesystem with an older kernel/userland,
660 especially an uncleanly mounted journaled filesystem. WAPBL
661 also requires the super block to be in the UFS2 format. You
662 can use fsck_ffs -c 4 to update the superblock format.
663
664 20080721:
665 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
666 isn't defined.
667
668 20080531:
669 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
670 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
671 utility needs to be rebuilt and reinstalled as older binaries
672 won't work correctly. The following sequence of commands:
673
674 $ (cd sys/sys/ && nbmake-$arch includes)
675 $ (cd sbin/drvctl/ && nbmake-$arch clean)
676 $ (cd sbin/drvctl/ && nbmake-$arch all)
677
678 leaves new drvctl utility in sbin/drvctl build directory.
679
680 20080503:
681 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
682
683 20080521:
684 For a while, unprivileged UPDATE builds would fail to
685 succeed at the checkflist stage, complaining that
686 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
687 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
688 If you already hit this problem, update the .mk file,
689 remove ${DESTDIR}/stand/<arch>, and re-run the build.
690
691 20080303:
692 Linker warnings are now fatal if $WARNS>0.
693
694 20080126:
695 The posix_fadvise system call has been changed from an assembly
696 stub, to a c file that calls an assembly stub. You need to
697 'rm -f posix_fadvise.* .depend' in the libc build directory to
698 avoid using the old assembly stub.
699
700 20071209:
701 The acpiec(4) driver has been split into two attachments. If you
702 get ACPI errors before the attachment, please update your kernel
703 configuration file appropriately or see GENERIC for more details.
704
705 20071115:
706 The it(4) driver has been renamed to itesio(4) and the old port
707 argument specified in the kernel configuration file is not valid
708 anymore. The itesio(4) driver now uses the Super I/O address port
709 rather than the EC address port. Please update your kernel
710 configuration file appropriately or see GENERIC for more details.
711
712 20071028:
713 The pccons(4) driver has been removed from the NetBSD/shark port.
714 You need to update any custom kernel configuration file you have
715 to remove any references to pccons (which includes removing the
716 now useless XSERVER option) and replace them with the correct
717 entries for the wscons driver. See the GENERIC configuration file
718 for more details.
719
720 20070913:
721 A latent bug in dhclient/dhcpd that caused it to be unable to
722 enumerate interfaces was fixed. The bug began to cause
723 problems after 20070911 when the kernel's SIOCGIFCONF
724 implementation was repaired. From 20070529 to 20070911 racoon
725 could not enumerate interfaces. (These are noted because
726 normal kernel/userspace version matching hygiene is not
727 sufficient to avoid this problem.) Ensure that both kernel
728 and userland are from after 20070913.
729
730 20070703:
731 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
732 calls the target-specific strip program, and the logic to pass
733 down STRIP from make has been removed. This requires a
734 re-installation of tools.
735
736 20070422:
737 The way OS emulations lookup filenames inside the emulation root
738 has been changed. Rather than modify the pathname (and copy back
739 to userspace) namei() and lookup() directly check the emulation
740 root. One side effect is that absolute symlinks inside the emulated
741 root file system will be relative to that file system - unless they
742 start /../ this is useful when the emulated root is a real install
743 that has such links.
744 This might affect symlinks that have been added to reference outside
745 the emulated root.
746
747 20070412:
748 The pckbc driver on sgimips IP32 has been removed. Use macekbc
749 instead. See the GENERIC32_IP3x kernel configuration for an
750 example.
751
752 20070319:
753 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
754 on many platforms due to incorrect flags settings. If you
755 updated and built after about 20070315, do "nbmake-$arch
756 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
757 rebuild of object files that might have been built
758 incorrectly, and ensure that you have at least
759 src/lib/libc/Makefile 1.130.
760
761 20070210:
762 src/sys/sys/{sa.h,savar.h} were removed.
763 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
764 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
765 will allow dependencies on those files to get get rebuilt
766
767 20070209:
768 The threading model was changed when the newlock2 branch
769 was merged to NetBSD-current. If you boot with a new
770 kernel (version 4.99.10), then you also need a new pthread
771 library (/usr/lib/libpthread.so.0.7). If you boot with
772 an old kernel, then you need the old pthread library
773 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
774 the pthread library in sync, old threaded applications should
775 continue to work with an old or new kernel. Note that named(8)
776 is the only threaded application in the base system.
777
778 20061214:
779 Following the move of string_to_flags() and flags_to_string()
780 from the bin/ls/ sources to libutil, users doing UPDATE builds
781 will need to do a "make cleandir" in
782 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
783 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
784 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
785 as the installation images in distrib/
786 in order to excise stale references to the old stat_flags.h header
787 file in the ls sources -- stat_flags.h has been removed.
788
789 20061108:
790 The configure script used in the src/tools/gcc compiler has been
791 changed to indicate that our libc has ssp support built-in and
792 does not depend on -lssp and -lssp-nonshared. You'll need to
793 make clean in src/tools/gcc first to rebuild the compiler.
794
795 20061009:
796 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
797 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
798
799 20060814:
800 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
801 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
802 kernel configuration for an example. X servers from the last
803 few years should cope.
804
805 20060703:
806 MPACPI is no more. We always configure PCI interrupts using ACPI
807 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
808 to ACPI_SCANPCI. Thanks to work from fvdl.
809
810 20060627:
811 socket(2) has changed, and its system call has been versioned.
812 For userlands with the old version of socket(2), make sure that
813 your kernel has 'options COMPAT_30' set, or else 'bad system call'
814 errors will result.
815
816 Hints for a more successful build:
817 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
818 Use build.sh, but do not use its "expert mode":
819 This will automatically build the tools in the
820 correct order, and it will keep the tools and the
821 new build products from interfering with the running
822 system. This will allow you to ignore most of the
823 other advice in this file.
824 Build a new kernel first:
825 This makes sure that any new system calls or features
826 expected by the new userland will be present. This
827 helps to avoid critical errors when upgrading.
828 Use object directories:
829 This helps to keep stale object
830 files from polluting the build if a Makefile "forgets"
831 about one. It also makes it easier to clean up after
832 a build. It's also necessary if you want to use the
833 same source tree for multiple machines.
834 To use object directories with build.sh:
835 a) invoke build.sh with the "-M" or "-O" options.
836 To use object directories without using build.sh:
837 a) cd /usr/src ; make cleandir
838 b) Add "OBJMACHINE=yes" to /etc/mk.conf
839 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
840 d) cd /usr/src ; make build
841 Note that running "make obj" in a directory will create
842 in obj.$MACHINE directory.
843 Build to a DESTDIR:
844 This helps to keep old installed files (especially libraries)
845 from interfering with the new build.
846 To build to a DESTDIR with build.sh, use the "-D" option.
847 To build to a DESTDIR without using build.sh, set the DESTDIR
848 environment variable before running make build. It should be
849 set to the pathname of an initially empty directory.
850 Problems: if you do not use build.sh, you might need to
851 update critical utilities without using DESTDIR since
852 nothing is executed from what is installed in DESTDIR.
853 (See critical utils, below.)
854 Build often:
855 This keeps critical utilities current enough to not choke
856 on any other part of the source tree that depends on up to
857 date functionality. If you use build.sh, you should not have
858 this problem.
859
860 What to do if things don't work:
861 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
862 When things don't work there are usually a few things that commonly
863 should be done.
864 1) make includes
865 This should be done automatically by make build.
866 2) cd share/mk && make install
867 Again, automatically done by make build.
868
869 Failsafe rebuild of a small part of the tree:
870 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
871 To make sure you rebuild something correctly you want to do
872 something like the following:
873 1) Make sure the includes and .mk files are up to date.
874 2) Make sure any program used to build the particular
875 utility is up to date. (yacc, lex, etc...)
876 3) cd ...path/to/util...
877 make cleandir
878 rm ...all obj directories...
879 make cleandir # yes, again
880 make obj
881 make depend && make
882
883 Failsafe rebuild of the entire tree:
884 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
885 If you really want to make sure the source tree is clean and
886 ready for a build try the following. Note that sourcing /etc/mk.conf
887 (a make(1) Makefile) in this manner is not right, and will not work
888 for anyone who uses any make(1) features in /etc/mk.conf.
889

922
923 Other problems and possible solutions:
924 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
925 Symptom:Complaints involving a Makefile.
926 Fix: Rebuild usr.bin/make:
927 cd usr.bin/make && make && make install
928 Or, a failsafe method if that doesn't work:
929 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
930
931 Fix: Make sure .mk files are up to date.
932 cd share/mk && make install
933
934 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
935 Fix: Rebuild usr.bin/config
936
937 Symptom:
938 Fix: Rebuild usr.bin/yacc
939
940 Symptom:
941 Fix: Rebuild usr.bin/lex
942
943 Symptom:
944 Fix: rm /usr/lib/libbfd.a
945
946 Symptom:Obsolete intermediate files are used during compilation
947 Fix: Try the following sequence of commands in the directory in question.
948 make cleandir; rm `make print-objdir`; make cleandir; make obj
949 (If you built the tree without "make obj" in the past, obsolete files
950 may remain. The command tries to clean everything up)
951
952 Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible
953 pointer type
954 Fix: Rebuild and install usr.bin/menuc
955
956 Symptom:mklocale not found during build in share/locale/ctype
957 Fix: Build and install usr.bin/mklocale
958
959 Symptom:undefined reference to `__assert13' or `__unsetenv13'
960 Fix: Rebuild and install lib/libc
961
962 Symptom:usr.bin/config fails to build.
963 Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
964
965 Symptom:undefined reference to `getprogname' or `setprogname'
966 Fix: Rebuild and install lib/libc
967
968 Symptom:lint does not understand the '-X' option
969 Fix: May need to build & install libs with NOLINT=1 before rebuilding lint
970
971 Symptom:Update build fails in src/tools/gcc complaining that a variable
972 (e.g. CPPFLAGS) has changed since the previous run.
973 Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
974
975 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
976 No such file or directory.
977 Cause: If a directory is created by mistake, then it is sometimes
978 deleted from the CVS repository using administrative commands
979 that bypass the normal cvs access controls. If your cvs working tree
980 contains references to a directory that has been deleted on the
981 server in this way, then "cvs update" reports this error.
982 Fix: Recursively delete the affected directory from your working tree
983 and try the update again.
984
