UPDATING revision 1.303 1 $NetBSD: UPDATING,v 1.303 2019/10/01 09:36:56 mrg Exp $
2
3 This file (UPDATING) is intended to be a brief reference to recent
4 changes that might cause problems in the build process, and a guide for
5 what to do if something doesn't work.
6
7 For a more detailed description of the recommended way to build NetBSD
8 using build.sh, see the BUILDING file.
9
10 Note that much of the advice in this UPDATING file was written before
11 build.sh existed. Nevertheless, the advice here may be useful for
12 working around specific problems with build.sh.
13
14 Sections are marked with "^^^^^". After the section on "Recent changes"
15 are several sections containing more general information.

23
24 GCC 8.3 was imported. Builds of src/tools/gcc may fail if
25 old builds with GCC 7 output now uses GCC 8. Clean this
26 directory, and also clean src/external/gpl3/gcc.

30 File with names that coincide with existing files' names on
31 case-insensitive file systems were inadvertently committed, for
32 radeon GPU firmware. We cannot mark these as obsolete for
33 postinstall to fix, so if you updated src since 2019-08-26, and
34 ran build.sh distribution or ran build.sh release, you must
35 manually delete the following files in your DESTDIR (which is
36 usually $OBJDIR/destir.$ARCH), or from / if you have installed
37 them:

106 We will re-import these radeon firmware images another way
107 later.
108
109 20190727:
110 The uefi bootloader has gained tftp support and needs a clean
111 build. If you do update builds, manually clean its object
112 directory by something like:
113 cd sys/arch/i386/stand/efiboot && make clean
114
115 20190723:
116 The jemalloc allocator in libc is now build without extended
117 debugging (for performance reasons). In update builds make sure
118 to rebuild it completly, by removing all affected object files,
119 including compat builds, something like:
120 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
121
122 20190207:
123 GCC 7 switched for many ports. Update builds are likely to fail.
124
125 20180924:
126 A newer OpenSSL version has been imported. If you are doing
127 update builds, make sure to remove all old obj dirs, like:
128 cd /usr/obj && find . -type d -name openssl | xargs rm -rf
129
130 20180717:
131 On aarch64 int64_t and related types have changed from long long
132 to long. This requires recompiling all C++ binaries.
133
134 20180713:
135 On amd64 and i386 static binaries are now build position
136 independend. This requires recompilation of all object
137 files used to create the crunched /rescue binary.
138 Clean the rescue directory in your obj directory before
139 doing an update build, otherwise linking will fail.
140
141 20180414:
142 Existing binutils was migrated to binutils.old. Manual
143 removal of tools/binutils objects directory may be required
144 to fix tools build failure.
145
146 20180311:
147 bdftopcf was updated and may need cleaning in the
148 src/external/mit/xorg/tools/bdftopcf subdirectory if there are
149 link errors.
150
151 20180212:
152 between OpenSSL and GCC updates, many things may fail to build.
153 any failure that looks like GCC or openssl is best handled by
154 a clean destdir and objdir. Full cleandir and destdir deletion
155 is recommended if build failures occur.
156
157 20171225:
158 removal of the vadvise syscall requires manual removal of all
159 associated files from the libc build object directory (including
160 the .depend files) - a command like:
161 cd $OBJ && find . -type d -name libc | xargs rm -rf
162 For architectures that support multiple "compat" binary targets,
163 you'll need to cleanup both the regular libc directory and the
164 compat ones (the above command will do that).
165
166 20171010:
167 a change to the build structure of external/bsd/acpica/bin/iasl
168 means that its objdir (or *.d and .depend at least) might need
169 to be manually removed - or a build done once without -u.
170
171 20170822:
172 a new version of GMP has been imported and probably
173 will break parts of builds related to themselves or GCC, both
174 in the tools and the native section. Remove all GCC, GMP, MPFR
175 and MPC objdirs or build once without -u.
176
177 20170816:
178 a new version of MPFR and MPC have been imported and probably
179 will break parts of builds related to themselves or GCC, both
180 in the tools and the native section. Remove all GCC, GMP, MPFR
181 and MPC objdirs or build once without -u.
182
183 20170402:
184 a new version of dhcpcd has been imported, which does not support
185 update builds from the previous version. Remove your
186 external/bsd/dhcpcd object dir or build once without -u.
187
188 20170211:
189 a new terminfo database has been imported.
190 The structure of it has changed slightly from prior versions and
191 an updated tic tool is required.
192 If you build.sh, don't use -u
193
194 20170207:
195 various arch dependent libc/exect.S files were removed
196 Either remove the obj directories (lib/libc and compat/amd64/i386/lib
197 if it exists) or do a clean build.
198 (This is a bug in the make system, it should be corrected without
199 human intervention, but isn't.)
200
201 20170104:
202 xinput build options have changed.
203 Remove the obj directory (external/mit/xorg/bin/xinput)
204 if you build.sh -u
205
206 20170103:
207 a new version of flex has been imported.
208 Remove the file from obj (external/bsd/flex)
209 if you build.sh -u
210
211 20161014:
212 a new version of OpenSSL has been imported.
213 Remove the files from obj (crypto/external/bsd/openssl)
214 if you build.sh -u
215
216 20161009:
217 a new version of dhcpcd has been imported with slightly changed
218 build infrastructure. When doing a build.sh -u this requires
219 pruning the external/bsd/dhcpcd objdir.
220
221 20160914:
222 i386, amd64, shark, ofppc and macppc have joined shark and x68k
223 ports in using xorg-server 1.18. This requires a clean destdir
224 and a clean objdir.
225
226 20160527:
227 i386 needs a full cleandir or objdir deletion because PIE has
228 been enabled. (see the amd64 entry two down for further info)
229
230 20160418:
231 libedit needs manual removal of all autogenerated files since
232 some of them are not autogenerated anymore. Remember that there
233 might be two copies of libedit if your platform builds "compat".
234
235 20160410:
236 amd64 needs full "make cleandir" or deletion of objdir now that
237 PIE has been enabled for amd64. PIE, or position-independent
238 executables, means all code, including executables and not just
239 shared libraries, is position-independent and hence able to be
240 relocated by ASLR, address space layout randomization.
241
242 The change was made in Makefile variables for compiler and
243 linker flags, for which make(1) does not record dependencies,
244 hence it is unable to detect that all .o files need rebuilding.
245
246 Partial rebuilds with some modified source files will likely
247 fail when linking executables, since the linker refuses to mix
248 position-independent code with position-dependent code in
249 position-independent executables:
250
251 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
252
253 20160401:
254 Ports switching to GCC 5.3 will need a full "make cleandir".
255 Some people have found that cleandir is not sufficient, so if
256 in doubt delete the entire object directory tree for gcc.
257
258 20160306:
259 NetBSD's regexp implementation is now part of libnbcompat.
260 Nblex, nbm4, nbpax, nbsed use it and they may crash on
261 non-NetBSD hosts if linked with stale object files produced
262 while they included a non-NetBSD regex.h.
263 In any case, you should "make cleandir" at least these tools
264 before updating your toolchain.
265
266 20160125:
267 Dtrace has been enabled by default on some architectures.
268 When doing an update build, make sure to clean the etc/mtree
269 object directory before starting the build - otherwise the
270 needed directories in destdir will not be created.
271 An easy way to do this is:
272 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
273
274 20150818:
275 New acpica requires "make cleandir" in src/external/bsd/acpica
276 again.
277
278 20150413:
279 New acpica requires "make cleandir" and reinstalling yacc
280 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
281 also "make cleandir" in /usr/src/external/bsd/acpica.
282
283 20150404:
284 Lint changes require a full rebuild of the tool, so make
285 sure to build without -u option to build.sh, or manually
286 do a make cleandir in src/tools/lint1 and
287 src/usr.bin/xlint.
288
289 20150310:
290 Improvements to openssl for arm mean that update builds of
291 the openssl libraries will fail. A make cleandir in
292 external/bsd/openssl/lib is needed
293
294 20141026:
295 A mishap during the import of pppd may cause your corruption
296 in your cvs directory if you happened to do a cvs update
297 during a short period of time. To fix, just remove the
298 directory src/external/bsd/ppp/dist/pppd completely
299 and let cvs restore it on next update.
300
301 20140721:
302 The src/external/mit/lua/src directory was accidentally created
303 and then deleted in the CVS repository. If you get errors like
304
305 cvs [update aborted]: cannot open directory
306 /cvsroot/src/external/mit/lua/src: No such file or directory
307
308 then delete your local copy of that directory tree and try again.
309
310 20140530:
311 ARM eABI switched to DWARF based exception handling. This requires
312 rebuilding all C++ code. It is strongly advised to do a clean build.
313
314 20140131:
315 The new compiler_rt/libc integration moved a few things. It is strongly
316 advised to do a clean build. At least lib/libc, the compat version(s)
317 of libc, libkern, rump and the kernels need to be cleaned.
318
319 20131227:
320 1. The new ntpd runs in a restricted mode to prevent amplification
321 attacks. If you need ntpdc to work you need to explicitly enable
322 mode7 in your config file. Make sure you put the necessary restrict
323 statements to avoid being exposed.
324 2. strncat has moved from lib/libc to common/lib/libc; you might need
325 to make clean in libc
326
327 20131129:
328 The GMP sources were updated, and builds will likely fail without
329 cleaning their build trees for both tools and in-tree, like below.
330
331 20131128:
332 The MPC and MPFR sources were updated, and builds may require their
333 tools and in-tree directories cleaned for successful updates.
334
335 20130605:
336 The kernel option FAST_IPSEC no longer exists, it's been renamed
337 to IPSEC (and the older IPSEC version removed).
338
339 20130605:
340 Previous freetype installations eroneously installed private
341 header files. If you are building against a non-empty $DESTDIR,
342 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
343
344 20130531:
345 The xdm update may cause build failure due to xdm.man being
346 in the obj tree. Make sure to ensure any like this:
347 nbmake: nbmake: don't know how to make xdm.man. Stop
348 is fixed by deleting the xdm.man in the obj tree.
349
350 20130530:
351 Updates of many xsrc packages will leave old .pc files around.
352 Best to clean out the xsrc objdir entirely before rebuilds.
353
354 20130301:
355 The removal of netiso requires manual removal of /usr/include/netiso
356 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
357
358 20120726:
359 The update of OpenSSL requires cleaning both the OpenSSL build
360 directory and DESTDIR. *Even non-update builds require cleaning
361 DESTDIR.* Builds done without taking these steps may fail, or in
362 some cases may succeed and install broken OpenSSL libraries that
363 cause third-party software to link incorrectly and/or crash.
364
365 20120507:
366 The database schema for makemandb was changed. You will
367 need to update the database using 'makemandb -f' or wait
368 for the next weekly run to fix it.
369
370 20120319:
371 sys/conf/Makefile.kern.inc has been modified to adjust the
372 size of db_symtab automatically. You need to update dbsym in
373 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
374 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
375 mk.conf.
376
377 20120216:
378 Default for MKCATPAGES changed to NO. Update builds will fail
379 unless DESTDIR is cleaned manually. If you built between 20120207
380 and 20120216, daily and weekly could have created an unreadable
381 /var/db/man.db index for apropos. Running makemandb -f or
382 the next run of weekly will fix it.
383
384 20111227:
385 If you built between 20111225 and 20111227 you need to remove
386 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
387 bump has been reverted.
388
389 20111125:
390 The "rnd" pseudodevice has been added to sys/conf/std, which
391 means it should no longer be explicitly listed in kernel
392 configuration files. The line "pseudo-device rnd" should be
393 removed from any custom kernel config files users may have.
394
395 20111119:
396 A problem with the datastructures used by the rndctl(8)
397 utility (pointers in datastructures in an array, making 32->64
398 bit compatibility very painful) has been fixed in a
399 non-backwards-compatible way. If you replace your kernel,
400 replace your rndctl executable too.
401
402 20111001:
403 the prop_*_send_syscall() functions from proplib(3) have been
404 changed and their new version is not backward compatible with the old
405 one. So ensure that all consumers of these functions (currently:
406 quota2 code and its tests) are updated together with the new lib.
407
408 20110817:
409 sparc has been changed to use GCC 4.5.3, so any objdir or
410 DESTDIR for them should be deleted before updating.
411
412 20110806:
413 i386 and amd64 have been changed to use GCC 4.5.3, so any
414 objdir or DESTDIR for them should be deleted before updating.
415
416 20110805:
417 The update to GCC 4.5.3 requires a non-trivial portion of
418 the tree to be cleaned. Best to delete both objdir and
419 DESTDIR before running this update. So far, only the
420 sparc64, mips and powerpc platforms have changed.
421
422 20110803:
423 The layout of external/public-domain/xz has changed. To do an
424 update build you will have to remove the contents of the OBJDIR
425 for external/public-domain/xz/bin by hand as the xz entry there
426 is now a directory.
427
428 20110410:
429 The configuration of src/tools/gcc has changed. To do an
430 update build you have to clean both tools/binutils and
431 tools/gcc by hand.
432
433 20110328:
434 Building the Xorg binary was moved into a subdirectory to fix
435 ordering issues with "make all". It may be necessary to remove
436 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
437 if your update build fails, as the "Xorg" entry there is now a
438 directory.
439
440 20110121:
441 Assembler files no longer use -traditional-cpp. This can break
442 the build of individual parts of the tree. This is handled
443 correctly by build.sh. Manual builds have to update /usr/share/mk
444 and re-run config(1) for any kernel configurations as needed.
445
446 20101217:
447 The tcpdump(8) program was changed to drop privileges and chroot(2)
448 by default. It may be necessary to manually update passwd(5) and
449 group(5) in order to make the program work with existing setups.
450
451 20101125:
452 The latest changes to setenv(3) dissallow setting environment
453 variables with names that contain '='. Revision 1.18 of env.c
454 assumed that this was allowed. Installing a new libc with an
455 old copy of /usr/bin/env causes env x=1 printenv | grep x= to
456 break which affects the autoconf tests for dependency finding,
457 so building gcc will end up printing:
458 checking dependency style of gcc... none
459 configure: error: no usable dependency style found
460 Fix it by rebuilding and re-installing env.
461
462 20101119:
463 Recent Xorg updates in xsrc/external/mit/ may cause various build
464 or run-time problems. Delete your entire DESTDIR and OBJDIR if you
465 have any build problems with xsrc, or problems with mismatched
466 versions between xorg-server and drivers.
467
468 20100604:
469 The update of ATF to 0.9 causes old tests written in shell to fail
470 unless they are rebuilt. If you are building with MKUPDATE=yes,
471 you need to clean the src/external/bsd/atf/tests/ and the src/tests/
472 trees by hand.
473
474 20100522:
475 Recent Xorg updates in xsrc/external/mit/ will cause various build
476 problems. Delete your entire DESTDIR and OBJDIR if you have any
477 build problems with xsrc.
478
479 20100522:
480 private section of <ctype.h> was splitted, and now mklocale(1)
481 include ctype_local.h, so you have to make cleandir in tools/mklocale.
482
483 20100520:
484 The location of the xkb compiled descriptions has changed. Please
485 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
486
487 20100222:
488 The shared objects file extension has been changed from .so to
489 .pico, in order to avoid conflicts with shared libraries names
490 libXX.so. All now stale regular .so files can be removed from
491 your object directories.
492
493 20100204:
494 The termcap database has been removed from the sources,
495 but has not been marked obsolete so it is not removed
496 from the system when upgrading.
497 As such, you will need to remove them from your object
498 and destination directories.
499
500 20091101:
501 After updating, it may be necessary to make the 'cleandir'
502 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
503 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
504 src/tools/lex/ and src/usr.bin/lex/.
505
506 20091001:
507 On amd64 you must rebuild tools (to get the new binutils)
508 before building a kernel, or the build fails on cpufunc.S.
509
510 20091001:
511 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
512 symlink, failing the build. Delete the link, and the subdir
513 it is in, and retry your build.
514
515 20090718:
516 libc build changed so that strchr() provides the extra entry
517 point for index(). Update build of libc.a (and libc_pic.a)
518 may fail because the archive contains the unwanted index.o.
519 (Similarly for strrchr() and rindex().)
520
521 20090709:
522 Native Xorg was upgraded again. Builds will probably fail again
523 without a clean objdir, at least for src/external/mit/xorg.
524
525 20090616:
526 Native Xorg was upgraded. Builds will need a clean objdir for
527 src/external/mit/xorg. Upgrading a system from sets will not
528 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
529 subdirectory has been changed into a file, and this needs to
530 be manually "rm -r"'ed before installing xbase.tgz.
531
532 20090501:
533 Several new functions were added to string.h/libc, and this
534 can cause autoconf problems during the tool build for people
535 who fail to clean out their tools objects properly. If you
536 note messages about stpcpy, stpncpy or strnlen accompanying a
537 failure during the tool build, clean out all your tools
538 objects and start again.
539
540 20090325:
541 The i386 port was switched to i486 default toolchain. This requires
542 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
543
544 20090126:
545 The __posix_fadvise50 system call changed assembly stub type. You
546 need to 'rm -f __posix_fadvise50.*' in the libc build directory
547 to avoid using the old assembly stub.
548
549 20090202:
550 pkg_install now depends on the pkgdb cache for automatic conflict
551 detection. It is recommented to rebuild the cache with
552 ``pkg_admin rebuild''.
553
554 20090110:
555 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
556 1. Make sure your kernel has COMPAT_50 in it. Build and install.
557 This is needed even in the MODULAR kernel because there is
558 conditionally compiled code in rtsock.c.
559 2. make sure build.sh completes and the binaries in a chroot work
560 before installing.
561 3. If you don't use build.sh and you build directly to root, and
562 your build breaks in the middle, don't despair. Make sure headers
563 are installed properly, and start building libraries first libc
564 and libutil, install them and then continue building all the
565 libraries in src/lib and src/gnu/lib and install them. Once
566 the new libraries are installed, you can restart the build.
567 4. If you compile packages and you notice link time warnings,
568 rebuild the required packages to update their shared libraries.
569 Any package you rebuild will require rebuilding all the packages
570 that depend on it.
571 5. Next time you run pwd_mkdb with the new binary, the file
572 will be upgraded and it will not be backwards compatible.
573 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
574 lastlogx(5)) have been versioned, and there is a heuristic
575 for utmp. You are better off removing the old files after
576 upgrading. The automated clearing of /var/run during
577 boot, and the automated rotating of files in /var/log by
578 newsyslog(8), may mean that you do not have to remove the
579 files manually.
580 7. The optional accounting file (/var/account/acct, see
581 accton(8)) has not been versioned, and will need to be
582 removed. The automatic rotation of the accounting file by
583 /etc/daily limits the bad consequences of failure to remove
584 the file.
585 8. Application software that writes time_t to binary files on
586 disk will break or need attention. Most notably: if you are
587 using PostgreSQL < 8.4, you need to dump your databases,
588 rebuild PostgreSQL with the new time_t, then restore.
589
590 20081219:
591 config(1) has been updated, and one of the files it creates -
592 swapnetbsd.o - has changed format. You need to rebuild config
593 (done automatically by build.sh) and then you need to rerun
594 config on all kernel configuration files before rebuilding those
595 kernels.
596
597 20081205:
598 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
599 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
600 set and will appear as extra files for MKX11=no update builds.
601
602 20081122:
603 On i386, various kernel options(4) in GENERIC including
604 file systems have been disabled and moved into kernel modules.
605 Before trying a new GENERIC kernel, you have to prepare the
606 following files as well as a new GENERIC kernel:
607
608 - build and install kernel modules from src/sys/modules
609
610 - install the latest bootloader, which will load a module
611 for the file system from which the kernel is loaded automatically
612
613 If you have to load your kernel from a file system which is not of
614 the same type as the root file system, you have to load the necessary
615 file system module manually on the boot prompt or in the boot.cfg file.
616
617 20080827:
618 If you built and installed a libc from sources between
619 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
620 which results in false errors reported by lint(1).
621 Since this breaks the libc build itself, manual help is
622 needed -- lint must be disabled temporarily, e.g.:
623 $ (cd lib/libc && make MKLINT=no dependall install)
624
625 20080813:
626 MKDEBUG build was broken because the .depend files did not know
627 about .go files. You need to remove all .depend files and rebuild.
628
629 20080802:
630 A regression in binary compatibility for pthread_mutex_t has
631 been fixed. Unfortunately, the price is breaking compatibility
632 for -current.
633
634 Threaded programs (using libpthread) and C++ programs (using
635 libstdc++) compiled after 20070907 and before 20080802 need to
636 be recompiled.
637
638 One way to find affected pkgsrc packages:
639
640 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
641 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
642
643 20080731:
644 WAPBL (metadata journaling support) has been added, but at this
645 time isn't backwards compatible with pre-WAPBL aware kernels
646 and userland (fsck_ffs in particular). Please make sure you
647 don't use a journaled filesystem with an older kernel/userland,
648 especially an uncleanly mounted journaled filesystem. WAPBL
649 also requires the super block to be in the UFS2 format. You
650 can use fsck_ffs -c 4 to update the superblock format.
651
652 20080721:
653 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
654 isn't defined.
655
656 20080531:
657 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
658 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
659 utility needs to be rebuilt and reinstalled as older binaries
660 won't work correctly. The following sequence of commands:
661
662 $ (cd sys/sys/ && nbmake-$arch includes)
663 $ (cd sbin/drvctl/ && nbmake-$arch clean)
664 $ (cd sbin/drvctl/ && nbmake-$arch all)
665
666 leaves new drvctl utility in sbin/drvctl build directory.
667
668 20080503:
669 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
670
671 20080521:
672 For a while, unprivileged UPDATE builds would fail to
673 succeed at the checkflist stage, complaining that
674 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
675 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
676 If you already hit this problem, update the .mk file,
677 remove ${DESTDIR}/stand/<arch>, and re-run the build.
678
679 20080303:
680 Linker warnings are now fatal if $WARNS>0.
681
682 20080126:
683 The posix_fadvise system call has been changed from an assembly
684 stub, to a c file that calls an assembly stub. You need to
685 'rm -f posix_fadvise.* .depend' in the libc build directory to
686 avoid using the old assembly stub.
687
688 20071209:
689 The acpiec(4) driver has been split into two attachments. If you
690 get ACPI errors before the attachment, please update your kernel
691 configuration file appropriately or see GENERIC for more details.
692
693 20071115:
694 The it(4) driver has been renamed to itesio(4) and the old port
695 argument specified in the kernel configuration file is not valid
696 anymore. The itesio(4) driver now uses the Super I/O address port
697 rather than the EC address port. Please update your kernel
698 configuration file appropriately or see GENERIC for more details.
699
700 20071028:
701 The pccons(4) driver has been removed from the NetBSD/shark port.
702 You need to update any custom kernel configuration file you have
703 to remove any references to pccons (which includes removing the
704 now useless XSERVER option) and replace them with the correct
705 entries for the wscons driver. See the GENERIC configuration file
706 for more details.
707
708 20070913:
709 A latent bug in dhclient/dhcpd that caused it to be unable to
710 enumerate interfaces was fixed. The bug began to cause
711 problems after 20070911 when the kernel's SIOCGIFCONF
712 implementation was repaired. From 20070529 to 20070911 racoon
713 could not enumerate interfaces. (These are noted because
714 normal kernel/userspace version matching hygiene is not
715 sufficient to avoid this problem.) Ensure that both kernel
716 and userland are from after 20070913.
717
718 20070703:
719 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
720 calls the target-specific strip program, and the logic to pass
721 down STRIP from make has been removed. This requires a
722 re-installation of tools.
723
724 20070422:
725 The way OS emulations lookup filenames inside the emulation root
726 has been changed. Rather than modify the pathname (and copy back
727 to userspace) namei() and lookup() directly check the emulation
728 root. One side effect is that absolute symlinks inside the emulated
729 root file system will be relative to that file system - unless they
730 start /../ this is useful when the emulated root is a real install
731 that has such links.
732 This might affect symlinks that have been added to reference outside
733 the emulated root.
734
735 20070412:
736 The pckbc driver on sgimips IP32 has been removed. Use macekbc
737 instead. See the GENERIC32_IP3x kernel configuration for an
738 example.
739
740 20070319:
741 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
742 on many platforms due to incorrect flags settings. If you
743 updated and built after about 20070315, do "nbmake-$arch
744 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
745 rebuild of object files that might have been built
746 incorrectly, and ensure that you have at least
747 src/lib/libc/Makefile 1.130.
748
749 20070210:
750 src/sys/sys/{sa.h,savar.h} were removed.
751 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
752 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
753 will allow dependencies on those files to get get rebuilt
754
755 20070209:
756 The threading model was changed when the newlock2 branch
757 was merged to NetBSD-current. If you boot with a new
758 kernel (version 4.99.10), then you also need a new pthread
759 library (/usr/lib/libpthread.so.0.7). If you boot with
760 an old kernel, then you need the old pthread library
761 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
762 the pthread library in sync, old threaded applications should
763 continue to work with an old or new kernel. Note that named(8)
764 is the only threaded application in the base system.
765
766 20061214:
767 Following the move of string_to_flags() and flags_to_string()
768 from the bin/ls/ sources to libutil, users doing UPDATE builds
769 will need to do a "make cleandir" in
770 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
771 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
772 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
773 as the installation images in distrib/
774 in order to excise stale references to the old stat_flags.h header
775 file in the ls sources -- stat_flags.h has been removed.
776
777 20061108:
778 The configure script used in the src/tools/gcc compiler has been
779 changed to indicate that our libc has ssp support built-in and
780 does not depend on -lssp and -lssp-nonshared. You'll need to
781 make clean in src/tools/gcc first to rebuild the compiler.
782
783 20061009:
784 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
785 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
786
787 20060814:
788 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
789 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
790 kernel configuration for an example. X servers from the last
791 few years should cope.
792
793 20060703:
794 MPACPI is no more. We always configure PCI interrupts using ACPI
795 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
796 to ACPI_SCANPCI. Thanks to work from fvdl.
797
798 20060627:
799 socket(2) has changed, and its system call has been versioned.
800 For userlands with the old version of socket(2), make sure that
801 your kernel has 'options COMPAT_30' set, or else 'bad system call'
802 errors will result.
803
804 Hints for a more successful build:
805 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
806 Use build.sh, but do not use its "expert mode":
807 This will automatically build the tools in the
808 correct order, and it will keep the tools and the
809 new build products from interfering with the running
810 system. This will allow you to ignore most of the
811 other advice in this file.
812 Build a new kernel first:
813 This makes sure that any new system calls or features
814 expected by the new userland will be present. This
815 helps to avoid critical errors when upgrading.
816 Use object directories:
817 This helps to keep stale object
818 files from polluting the build if a Makefile "forgets"
819 about one. It also makes it easier to clean up after
820 a build. It's also necessary if you want to use the
821 same source tree for multiple machines.
822 To use object directories with build.sh:
823 a) invoke build.sh with the "-M" or "-O" options.
824 To use object directories without using build.sh:
825 a) cd /usr/src ; make cleandir
826 b) Add "OBJMACHINE=yes" to /etc/mk.conf
827 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
828 d) cd /usr/src ; make build
829 Note that running "make obj" in a directory will create
830 in obj.$MACHINE directory.
831 Build to a DESTDIR:
832 This helps to keep old installed files (especially libraries)
833 from interfering with the new build.
834 To build to a DESTDIR with build.sh, use the "-D" option.
835 To build to a DESTDIR without using build.sh, set the DESTDIR
836 environment variable before running make build. It should be
837 set to the pathname of an initially empty directory.
838 Problems: if you do not use build.sh, you might need to
839 update critical utilities without using DESTDIR since
840 nothing is executed from what is installed in DESTDIR.
841 (See critical utils, below.)
842 Build often:
843 This keeps critical utilities current enough to not choke
844 on any other part of the source tree that depends on up to
845 date functionality. If you use build.sh, you should not have
846 this problem.
847
848 What to do if things don't work:
849 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
850 When things don't work there are usually a few things that commonly
851 should be done.
852 1) make includes
853 This should be done automatically by make build.
854 2) cd share/mk && make install
855 Again, automatically done by make build.
856
857 Failsafe rebuild of a small part of the tree:
858 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
859 To make sure you rebuild something correctly you want to do
860 something like the following:
861 1) Make sure the includes and .mk files are up to date.
862 2) Make sure any program used to build the particular
863 utility is up to date. (yacc, lex, etc...)
864 3) cd ...path/to/util...
865 make cleandir
866 rm ...all obj directories...
867 make cleandir # yes, again
868 make obj
869 make depend && make
870
871 Failsafe rebuild of the entire tree:
872 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
873 If you really want to make sure the source tree is clean and
874 ready for a build try the following. Note that sourcing /etc/mk.conf
875 (a make(1) Makefile) in this manner is not right, and will not work
876 for anyone who uses any make(1) features in /etc/mk.conf.
877

910
911 Other problems and possible solutions:
912 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
913 Symptom:Complaints involving a Makefile.
914 Fix: Rebuild usr.bin/make:
915 cd usr.bin/make && make && make install
916 Or, a failsafe method if that doesn't work:
917 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
918
919 Fix: Make sure .mk files are up to date.
920 cd share/mk && make install
921
922 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
923 Fix: Rebuild usr.bin/config
924
925 Symptom:
926 Fix: Rebuild usr.bin/yacc
927
928 Symptom:
929 Fix: Rebuild usr.bin/lex
930
931 Symptom:
932 Fix: rm /usr/lib/libbfd.a
933
934 Symptom:Obsolete intermediate files are used during compilation
935 Fix: Try the following sequence of commands in the directory in question.
936 make cleandir; rm `make print-objdir`; make cleandir; make obj
937 (If you built the tree without "make obj" in the past, obsolete files
938 may remain. The command tries to clean everything up)
939
940 Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible
941 pointer type
942 Fix: Rebuild and install usr.bin/menuc
943
944 Symptom:mklocale not found during build in share/locale/ctype
945 Fix: Build and install usr.bin/mklocale
946
947 Symptom:undefined reference to `__assert13' or `__unsetenv13'
948 Fix: Rebuild and install lib/libc
949
950 Symptom:usr.bin/config fails to build.
951 Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
952
953 Symptom:undefined reference to `getprogname' or `setprogname'
954 Fix: Rebuild and install lib/libc
955
956 Symptom:lint does not understand the '-X' option
957 Fix: May need to build & install libs with NOLINT=1 before rebuilding lint
958
959 Symptom:Update build fails in src/tools/gcc complaining that a variable
960 (e.g. CPPFLAGS) has changed since the previous run.
961 Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
962
963 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
964 No such file or directory.
965 Cause: If a directory is created by mistake, then it is sometimes
966 deleted from the CVS repository using administrative commands
967 that bypass the normal cvs access controls. If your cvs working tree
968 contains references to a directory that has been deleted on the
969 server in this way, then "cvs update" reports this error.
970 Fix: Recursively delete the affected directory from your working tree
971 and try the update again.
972
