UPDATING revision 1.302 1 $NetBSD: UPDATING,v 1.302 2019/09/03 15:38:52 riastradh 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.

14 Sections are marked with "^^^^^". After the section on "Recent changes"
15 are several sections containing more general information.

23
24 File with names that coincide with existing files' names on
25 case-insensitive file systems were inadvertently committed, for
26 radeon GPU firmware. We cannot mark these as obsolete for
27 postinstall to fix, so if you updated src since 2019-08-26, and
28 ran build.sh distribution or ran build.sh release, you must
29 manually delete the following files in your DESTDIR (which is
30 usually $OBJDIR/destir.$ARCH), or from / if you have installed
31 them:

100 We will re-import these radeon firmware images another way
101 later.
102
103 20190727:
104 The uefi bootloader has gained tftp support and needs a clean
105 build. If you do update builds, manually clean its object
106 directory by something like:
107 cd sys/arch/i386/stand/efiboot && make clean
108
109 20190723:
110 The jemalloc allocator in libc is now build without extended
111 debugging (for performance reasons). In update builds make sure
112 to rebuild it completly, by removing all affected object files,
113 including compat builds, something like:
114 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
115
116 20190207:
117 GCC 7 switched for many ports. Update builds are likely to fail.
118
119 20180924:
120 A newer OpenSSL version has been imported. If you are doing
121 update builds, make sure to remove all old obj dirs, like:
122 cd /usr/obj && find . -type d -name openssl | xargs rm -rf
123
124 20180717:
125 On aarch64 int64_t and related types have changed from long long
126 to long. This requires recompiling all C++ binaries.
127
128 20180713:
129 On amd64 and i386 static binaries are now build position
130 independend. This requires recompilation of all object
131 files used to create the crunched /rescue binary.
132 Clean the rescue directory in your obj directory before
133 doing an update build, otherwise linking will fail.
134
135 20180414:
136 Existing binutils was migrated to binutils.old. Manual
137 removal of tools/binutils objects directory may be required
138 to fix tools build failure.
139
140 20180311:
141 bdftopcf was updated and may need cleaning in the
142 src/external/mit/xorg/tools/bdftopcf subdirectory if there are
143 link errors.
144
145 20180212:
146 between OpenSSL and GCC updates, many things may fail to build.
147 any failure that looks like GCC or openssl is best handled by
148 a clean destdir and objdir. Full cleandir and destdir deletion
149 is recommended if build failures occur.
150
151 20171225:
152 removal of the vadvise syscall requires manual removal of all
153 associated files from the libc build object directory (including
154 the .depend files) - a command like:
155 cd $OBJ && find . -type d -name libc | xargs rm -rf
156 For architectures that support multiple "compat" binary targets,
157 you'll need to cleanup both the regular libc directory and the
158 compat ones (the above command will do that).
159
160 20171010:
161 a change to the build structure of external/bsd/acpica/bin/iasl
162 means that its objdir (or *.d and .depend at least) might need
163 to be manually removed - or a build done once without -u.
164
165 20170822:
166 a new version of GMP has been imported and probably
167 will break parts of builds related to themselves or GCC, both
168 in the tools and the native section. Remove all GCC, GMP, MPFR
169 and MPC objdirs or build once without -u.
170
171 20170816:
172 a new version of MPFR and MPC have 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 20170402:
178 a new version of dhcpcd has been imported, which does not support
179 update builds from the previous version. Remove your
180 external/bsd/dhcpcd object dir or build once without -u.
181
182 20170211:
183 a new terminfo database has been imported.
184 The structure of it has changed slightly from prior versions and
185 an updated tic tool is required.
186 If you build.sh, don't use -u
187
188 20170207:
189 various arch dependent libc/exect.S files were removed
190 Either remove the obj directories (lib/libc and compat/amd64/i386/lib
191 if it exists) or do a clean build.
192 (This is a bug in the make system, it should be corrected without
193 human intervention, but isn't.)
194
195 20170104:
196 xinput build options have changed.
197 Remove the obj directory (external/mit/xorg/bin/xinput)
198 if you build.sh -u
199
200 20170103:
201 a new version of flex has been imported.
202 Remove the file from obj (external/bsd/flex)
203 if you build.sh -u
204
205 20161014:
206 a new version of OpenSSL has been imported.
207 Remove the files from obj (crypto/external/bsd/openssl)
208 if you build.sh -u
209
210 20161009:
211 a new version of dhcpcd has been imported with slightly changed
212 build infrastructure. When doing a build.sh -u this requires
213 pruning the external/bsd/dhcpcd objdir.
214
215 20160914:
216 i386, amd64, shark, ofppc and macppc have joined shark and x68k
217 ports in using xorg-server 1.18. This requires a clean destdir
218 and a clean objdir.
219
220 20160527:
221 i386 needs a full cleandir or objdir deletion because PIE has
222 been enabled. (see the amd64 entry two down for further info)
223
224 20160418:
225 libedit needs manual removal of all autogenerated files since
226 some of them are not autogenerated anymore. Remember that there
227 might be two copies of libedit if your platform builds "compat".
228
229 20160410:
230 amd64 needs full "make cleandir" or deletion of objdir now that
231 PIE has been enabled for amd64. PIE, or position-independent
232 executables, means all code, including executables and not just
233 shared libraries, is position-independent and hence able to be
234 relocated by ASLR, address space layout randomization.
235
236 The change was made in Makefile variables for compiler and
237 linker flags, for which make(1) does not record dependencies,
238 hence it is unable to detect that all .o files need rebuilding.
239
240 Partial rebuilds with some modified source files will likely
241 fail when linking executables, since the linker refuses to mix
242 position-independent code with position-dependent code in
243 position-independent executables:
244
245 .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
246
247 20160401:
248 Ports switching to GCC 5.3 will need a full "make cleandir".
249 Some people have found that cleandir is not sufficient, so if
250 in doubt delete the entire object directory tree for gcc.
251
252 20160306:
253 NetBSD's regexp implementation is now part of libnbcompat.
254 Nblex, nbm4, nbpax, nbsed use it and they may crash on
255 non-NetBSD hosts if linked with stale object files produced
256 while they included a non-NetBSD regex.h.
257 In any case, you should "make cleandir" at least these tools
258 before updating your toolchain.
259
260 20160125:
261 Dtrace has been enabled by default on some architectures.
262 When doing an update build, make sure to clean the etc/mtree
263 object directory before starting the build - otherwise the
264 needed directories in destdir will not be created.
265 An easy way to do this is:
266 cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
267
268 20150818:
269 New acpica requires "make cleandir" in src/external/bsd/acpica
270 again.
271
272 20150413:
273 New acpica requires "make cleandir" and reinstalling yacc
274 in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
275 also "make cleandir" in /usr/src/external/bsd/acpica.
276
277 20150404:
278 Lint changes require a full rebuild of the tool, so make
279 sure to build without -u option to build.sh, or manually
280 do a make cleandir in src/tools/lint1 and
281 src/usr.bin/xlint.
282
283 20150310:
284 Improvements to openssl for arm mean that update builds of
285 the openssl libraries will fail. A make cleandir in
286 external/bsd/openssl/lib is needed
287
288 20141026:
289 A mishap during the import of pppd may cause your corruption
290 in your cvs directory if you happened to do a cvs update
291 during a short period of time. To fix, just remove the
292 directory src/external/bsd/ppp/dist/pppd completely
293 and let cvs restore it on next update.
294
295 20140721:
296 The src/external/mit/lua/src directory was accidentally created
297 and then deleted in the CVS repository. If you get errors like
298
299 cvs [update aborted]: cannot open directory
300 /cvsroot/src/external/mit/lua/src: No such file or directory
301
302 then delete your local copy of that directory tree and try again.
303
304 20140530:
305 ARM eABI switched to DWARF based exception handling. This requires
306 rebuilding all C++ code. It is strongly advised to do a clean build.
307
308 20140131:
309 The new compiler_rt/libc integration moved a few things. It is strongly
310 advised to do a clean build. At least lib/libc, the compat version(s)
311 of libc, libkern, rump and the kernels need to be cleaned.
312
313 20131227:
314 1. The new ntpd runs in a restricted mode to prevent amplification
315 attacks. If you need ntpdc to work you need to explicitly enable
316 mode7 in your config file. Make sure you put the necessary restrict
317 statements to avoid being exposed.
318 2. strncat has moved from lib/libc to common/lib/libc; you might need
319 to make clean in libc
320
321 20131129:
322 The GMP sources were updated, and builds will likely fail without
323 cleaning their build trees for both tools and in-tree, like below.
324
325 20131128:
326 The MPC and MPFR sources were updated, and builds may require their
327 tools and in-tree directories cleaned for successful updates.
328
329 20130605:
330 The kernel option FAST_IPSEC no longer exists, it's been renamed
331 to IPSEC (and the older IPSEC version removed).
332
333 20130605:
334 Previous freetype installations eroneously installed private
335 header files. If you are building against a non-empty $DESTDIR,
336 please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
337
338 20130531:
339 The xdm update may cause build failure due to xdm.man being
340 in the obj tree. Make sure to ensure any like this:
341 nbmake: nbmake: don't know how to make xdm.man. Stop
342 is fixed by deleting the xdm.man in the obj tree.
343
344 20130530:
345 Updates of many xsrc packages will leave old .pc files around.
346 Best to clean out the xsrc objdir entirely before rebuilds.
347
348 20130301:
349 The removal of netiso requires manual removal of /usr/include/netiso
350 prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
351
352 20120726:
353 The update of OpenSSL requires cleaning both the OpenSSL build
354 directory and DESTDIR. *Even non-update builds require cleaning
355 DESTDIR.* Builds done without taking these steps may fail, or in
356 some cases may succeed and install broken OpenSSL libraries that
357 cause third-party software to link incorrectly and/or crash.
358
359 20120507:
360 The database schema for makemandb was changed. You will
361 need to update the database using 'makemandb -f' or wait
362 for the next weekly run to fix it.
363
364 20120319:
365 sys/conf/Makefile.kern.inc has been modified to adjust the
366 size of db_symtab automatically. You need to update dbsym in
367 your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
368 you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
369 mk.conf.
370
371 20120216:
372 Default for MKCATPAGES changed to NO. Update builds will fail
373 unless DESTDIR is cleaned manually. If you built between 20120207
374 and 20120216, daily and weekly could have created an unreadable
375 /var/db/man.db index for apropos. Running makemandb -f or
376 the next run of weekly will fix it.
377
378 20111227:
379 If you built between 20111225 and 20111227 you need to remove
380 /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
381 bump has been reverted.
382
383 20111125:
384 The "rnd" pseudodevice has been added to sys/conf/std, which
385 means it should no longer be explicitly listed in kernel
386 configuration files. The line "pseudo-device rnd" should be
387 removed from any custom kernel config files users may have.
388
389 20111119:
390 A problem with the datastructures used by the rndctl(8)
391 utility (pointers in datastructures in an array, making 32->64
392 bit compatibility very painful) has been fixed in a
393 non-backwards-compatible way. If you replace your kernel,
394 replace your rndctl executable too.
395
396 20111001:
397 the prop_*_send_syscall() functions from proplib(3) have been
398 changed and their new version is not backward compatible with the old
399 one. So ensure that all consumers of these functions (currently:
400 quota2 code and its tests) are updated together with the new lib.
401
402 20110817:
403 sparc has been changed to use GCC 4.5.3, so any objdir or
404 DESTDIR for them should be deleted before updating.
405
406 20110806:
407 i386 and amd64 have been changed to use GCC 4.5.3, so any
408 objdir or DESTDIR for them should be deleted before updating.
409
410 20110805:
411 The update to GCC 4.5.3 requires a non-trivial portion of
412 the tree to be cleaned. Best to delete both objdir and
413 DESTDIR before running this update. So far, only the
414 sparc64, mips and powerpc platforms have changed.
415
416 20110803:
417 The layout of external/public-domain/xz has changed. To do an
418 update build you will have to remove the contents of the OBJDIR
419 for external/public-domain/xz/bin by hand as the xz entry there
420 is now a directory.
421
422 20110410:
423 The configuration of src/tools/gcc has changed. To do an
424 update build you have to clean both tools/binutils and
425 tools/gcc by hand.
426
427 20110328:
428 Building the Xorg binary was moved into a subdirectory to fix
429 ordering issues with "make all". It may be necessary to remove
430 the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
431 if your update build fails, as the "Xorg" entry there is now a
432 directory.
433
434 20110121:
435 Assembler files no longer use -traditional-cpp. This can break
436 the build of individual parts of the tree. This is handled
437 correctly by build.sh. Manual builds have to update /usr/share/mk
438 and re-run config(1) for any kernel configurations as needed.
439
440 20101217:
441 The tcpdump(8) program was changed to drop privileges and chroot(2)
442 by default. It may be necessary to manually update passwd(5) and
443 group(5) in order to make the program work with existing setups.
444
445 20101125:
446 The latest changes to setenv(3) dissallow setting environment
447 variables with names that contain '='. Revision 1.18 of env.c
448 assumed that this was allowed. Installing a new libc with an
449 old copy of /usr/bin/env causes env x=1 printenv | grep x= to
450 break which affects the autoconf tests for dependency finding,
451 so building gcc will end up printing:
452 checking dependency style of gcc... none
453 configure: error: no usable dependency style found
454 Fix it by rebuilding and re-installing env.
455
456 20101119:
457 Recent Xorg updates in xsrc/external/mit/ may cause various build
458 or run-time problems. Delete your entire DESTDIR and OBJDIR if you
459 have any build problems with xsrc, or problems with mismatched
460 versions between xorg-server and drivers.
461
462 20100604:
463 The update of ATF to 0.9 causes old tests written in shell to fail
464 unless they are rebuilt. If you are building with MKUPDATE=yes,
465 you need to clean the src/external/bsd/atf/tests/ and the src/tests/
466 trees by hand.
467
468 20100522:
469 Recent Xorg updates in xsrc/external/mit/ will cause various build
470 problems. Delete your entire DESTDIR and OBJDIR if you have any
471 build problems with xsrc.
472
473 20100522:
474 private section of <ctype.h> was splitted, and now mklocale(1)
475 include ctype_local.h, so you have to make cleandir in tools/mklocale.
476
477 20100520:
478 The location of the xkb compiled descriptions has changed. Please
479 remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
480
481 20100222:
482 The shared objects file extension has been changed from .so to
483 .pico, in order to avoid conflicts with shared libraries names
484 libXX.so. All now stale regular .so files can be removed from
485 your object directories.
486
487 20100204:
488 The termcap database has been removed from the sources,
489 but has not been marked obsolete so it is not removed
490 from the system when upgrading.
491 As such, you will need to remove them from your object
492 and destination directories.
493
494 20091101:
495 After updating, it may be necessary to make the 'cleandir'
496 target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
497 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
498 src/tools/lex/ and src/usr.bin/lex/.
499
500 20091001:
501 On amd64 you must rebuild tools (to get the new binutils)
502 before building a kernel, or the build fails on cpufunc.S.
503
504 20091001:
505 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
506 symlink, failing the build. Delete the link, and the subdir
507 it is in, and retry your build.
508
509 20090718:
510 libc build changed so that strchr() provides the extra entry
511 point for index(). Update build of libc.a (and libc_pic.a)
512 may fail because the archive contains the unwanted index.o.
513 (Similarly for strrchr() and rindex().)
514
515 20090709:
516 Native Xorg was upgraded again. Builds will probably fail again
517 without a clean objdir, at least for src/external/mit/xorg.
518
519 20090616:
520 Native Xorg was upgraded. Builds will need a clean objdir for
521 src/external/mit/xorg. Upgrading a system from sets will not
522 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
523 subdirectory has been changed into a file, and this needs to
524 be manually "rm -r"'ed before installing xbase.tgz.
525
526 20090501:
527 Several new functions were added to string.h/libc, and this
528 can cause autoconf problems during the tool build for people
529 who fail to clean out their tools objects properly. If you
530 note messages about stpcpy, stpncpy or strnlen accompanying a
531 failure during the tool build, clean out all your tools
532 objects and start again.
533
534 20090325:
535 The i386 port was switched to i486 default toolchain. This requires
536 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
537
538 20090126:
539 The __posix_fadvise50 system call changed assembly stub type. You
540 need to 'rm -f __posix_fadvise50.*' in the libc build directory
541 to avoid using the old assembly stub.
542
543 20090202:
544 pkg_install now depends on the pkgdb cache for automatic conflict
545 detection. It is recommented to rebuild the cache with
546 ``pkg_admin rebuild''.
547
548 20090110:
549 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
550 1. Make sure your kernel has COMPAT_50 in it. Build and install.
551 This is needed even in the MODULAR kernel because there is
552 conditionally compiled code in rtsock.c.
553 2. make sure build.sh completes and the binaries in a chroot work
554 before installing.
555 3. If you don't use build.sh and you build directly to root, and
556 your build breaks in the middle, don't despair. Make sure headers
557 are installed properly, and start building libraries first libc
558 and libutil, install them and then continue building all the
559 libraries in src/lib and src/gnu/lib and install them. Once
560 the new libraries are installed, you can restart the build.
561 4. If you compile packages and you notice link time warnings,
562 rebuild the required packages to update their shared libraries.
563 Any package you rebuild will require rebuilding all the packages
564 that depend on it.
565 5. Next time you run pwd_mkdb with the new binary, the file
566 will be upgraded and it will not be backwards compatible.
567 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
568 lastlogx(5)) have been versioned, and there is a heuristic
569 for utmp. You are better off removing the old files after
570 upgrading. The automated clearing of /var/run during
571 boot, and the automated rotating of files in /var/log by
572 newsyslog(8), may mean that you do not have to remove the
573 files manually.
574 7. The optional accounting file (/var/account/acct, see
575 accton(8)) has not been versioned, and will need to be
576 removed. The automatic rotation of the accounting file by
577 /etc/daily limits the bad consequences of failure to remove
578 the file.
579 8. Application software that writes time_t to binary files on
580 disk will break or need attention. Most notably: if you are
581 using PostgreSQL < 8.4, you need to dump your databases,
582 rebuild PostgreSQL with the new time_t, then restore.
583
584 20081219:
585 config(1) has been updated, and one of the files it creates -
586 swapnetbsd.o - has changed format. You need to rebuild config
587 (done automatically by build.sh) and then you need to rerun
588 config on all kernel configuration files before rebuilding those
589 kernels.
590
591 20081205:
592 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
593 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
594 set and will appear as extra files for MKX11=no update builds.
595
596 20081122:
597 On i386, various kernel options(4) in GENERIC including
598 file systems have been disabled and moved into kernel modules.
599 Before trying a new GENERIC kernel, you have to prepare the
600 following files as well as a new GENERIC kernel:
601
602 - build and install kernel modules from src/sys/modules
603
604 - install the latest bootloader, which will load a module
605 for the file system from which the kernel is loaded automatically
606
607 If you have to load your kernel from a file system which is not of
608 the same type as the root file system, you have to load the necessary
609 file system module manually on the boot prompt or in the boot.cfg file.
610
611 20080827:
612 If you built and installed a libc from sources between
613 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
614 which results in false errors reported by lint(1).
615 Since this breaks the libc build itself, manual help is
616 needed -- lint must be disabled temporarily, e.g.:
617 $ (cd lib/libc && make MKLINT=no dependall install)
618
619 20080813:
620 MKDEBUG build was broken because the .depend files did not know
621 about .go files. You need to remove all .depend files and rebuild.
622
623 20080802:
624 A regression in binary compatibility for pthread_mutex_t has
625 been fixed. Unfortunately, the price is breaking compatibility
626 for -current.
627
628 Threaded programs (using libpthread) and C++ programs (using
629 libstdc++) compiled after 20070907 and before 20080802 need to
630 be recompiled.
631
632 One way to find affected pkgsrc packages:
633
634 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
635 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
636
637 20080731:
638 WAPBL (metadata journaling support) has been added, but at this
639 time isn't backwards compatible with pre-WAPBL aware kernels
640 and userland (fsck_ffs in particular). Please make sure you
641 don't use a journaled filesystem with an older kernel/userland,
642 especially an uncleanly mounted journaled filesystem. WAPBL
643 also requires the super block to be in the UFS2 format. You
644 can use fsck_ffs -c 4 to update the superblock format.
645
646 20080721:
647 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
648 isn't defined.
649
650 20080531:
651 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
652 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
653 utility needs to be rebuilt and reinstalled as older binaries
654 won't work correctly. The following sequence of commands:
655
656 $ (cd sys/sys/ && nbmake-$arch includes)
657 $ (cd sbin/drvctl/ && nbmake-$arch clean)
658 $ (cd sbin/drvctl/ && nbmake-$arch all)
659
660 leaves new drvctl utility in sbin/drvctl build directory.
661
662 20080503:
663 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
664
665 20080521:
666 For a while, unprivileged UPDATE builds would fail to
667 succeed at the checkflist stage, complaining that
668 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
669 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
670 If you already hit this problem, update the .mk file,
671 remove ${DESTDIR}/stand/<arch>, and re-run the build.
672
673 20080303:
674 Linker warnings are now fatal if $WARNS>0.
675
676 20080126:
677 The posix_fadvise system call has been changed from an assembly
678 stub, to a c file that calls an assembly stub. You need to
679 'rm -f posix_fadvise.* .depend' in the libc build directory to
680 avoid using the old assembly stub.
681
682 20071209:
683 The acpiec(4) driver has been split into two attachments. If you
684 get ACPI errors before the attachment, please update your kernel
685 configuration file appropriately or see GENERIC for more details.
686
687 20071115:
688 The it(4) driver has been renamed to itesio(4) and the old port
689 argument specified in the kernel configuration file is not valid
690 anymore. The itesio(4) driver now uses the Super I/O address port
691 rather than the EC address port. Please update your kernel
692 configuration file appropriately or see GENERIC for more details.
693
694 20071028:
695 The pccons(4) driver has been removed from the NetBSD/shark port.
696 You need to update any custom kernel configuration file you have
697 to remove any references to pccons (which includes removing the
698 now useless XSERVER option) and replace them with the correct
699 entries for the wscons driver. See the GENERIC configuration file
700 for more details.
701
702 20070913:
703 A latent bug in dhclient/dhcpd that caused it to be unable to
704 enumerate interfaces was fixed. The bug began to cause
705 problems after 20070911 when the kernel's SIOCGIFCONF
706 implementation was repaired. From 20070529 to 20070911 racoon
707 could not enumerate interfaces. (These are noted because
708 normal kernel/userspace version matching hygiene is not
709 sufficient to avoid this problem.) Ensure that both kernel
710 and userland are from after 20070913.
711
712 20070703:
713 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
714 calls the target-specific strip program, and the logic to pass
715 down STRIP from make has been removed. This requires a
716 re-installation of tools.
717
718 20070422:
719 The way OS emulations lookup filenames inside the emulation root
720 has been changed. Rather than modify the pathname (and copy back
721 to userspace) namei() and lookup() directly check the emulation
722 root. One side effect is that absolute symlinks inside the emulated
723 root file system will be relative to that file system - unless they
724 start /../ this is useful when the emulated root is a real install
725 that has such links.
726 This might affect symlinks that have been added to reference outside
727 the emulated root.
728
729 20070412:
730 The pckbc driver on sgimips IP32 has been removed. Use macekbc
731 instead. See the GENERIC32_IP3x kernel configuration for an
732 example.
733
734 20070319:
735 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
736 on many platforms due to incorrect flags settings. If you
737 updated and built after about 20070315, do "nbmake-$arch
738 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
739 rebuild of object files that might have been built
740 incorrectly, and ensure that you have at least
741 src/lib/libc/Makefile 1.130.
742
743 20070210:
744 src/sys/sys/{sa.h,savar.h} were removed.
745 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
746 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
747 will allow dependencies on those files to get get rebuilt
748
749 20070209:
750 The threading model was changed when the newlock2 branch
751 was merged to NetBSD-current. If you boot with a new
752 kernel (version 4.99.10), then you also need a new pthread
753 library (/usr/lib/libpthread.so.0.7). If you boot with
754 an old kernel, then you need the old pthread library
755 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
756 the pthread library in sync, old threaded applications should
757 continue to work with an old or new kernel. Note that named(8)
758 is the only threaded application in the base system.
759
760 20061214:
761 Following the move of string_to_flags() and flags_to_string()
762 from the bin/ls/ sources to libutil, users doing UPDATE builds
763 will need to do a "make cleandir" in
764 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
765 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
766 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
767 as the installation images in distrib/
768 in order to excise stale references to the old stat_flags.h header
769 file in the ls sources -- stat_flags.h has been removed.
770
771 20061108:
772 The configure script used in the src/tools/gcc compiler has been
773 changed to indicate that our libc has ssp support built-in and
774 does not depend on -lssp and -lssp-nonshared. You'll need to
775 make clean in src/tools/gcc first to rebuild the compiler.
776
777 20061009:
778 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
779 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
780
781 20060814:
782 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
783 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
784 kernel configuration for an example. X servers from the last
785 few years should cope.
786
787 20060703:
788 MPACPI is no more. We always configure PCI interrupts using ACPI
789 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
790 to ACPI_SCANPCI. Thanks to work from fvdl.
791
792 20060627:
793 socket(2) has changed, and its system call has been versioned.
794 For userlands with the old version of socket(2), make sure that
795 your kernel has 'options COMPAT_30' set, or else 'bad system call'
796 errors will result.
797
798 Hints for a more successful build:
799 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
800 Use build.sh, but do not use its "expert mode":
801 This will automatically build the tools in the
802 correct order, and it will keep the tools and the
803 new build products from interfering with the running
804 system. This will allow you to ignore most of the
805 other advice in this file.
806 Build a new kernel first:
807 This makes sure that any new system calls or features
808 expected by the new userland will be present. This
809 helps to avoid critical errors when upgrading.
810 Use object directories:
811 This helps to keep stale object
812 files from polluting the build if a Makefile "forgets"
813 about one. It also makes it easier to clean up after
814 a build. It's also necessary if you want to use the
815 same source tree for multiple machines.
816 To use object directories with build.sh:
817 a) invoke build.sh with the "-M" or "-O" options.
818 To use object directories without using build.sh:
819 a) cd /usr/src ; make cleandir
820 b) Add "OBJMACHINE=yes" to /etc/mk.conf
821 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
822 d) cd /usr/src ; make build
823 Note that running "make obj" in a directory will create
824 in obj.$MACHINE directory.
825 Build to a DESTDIR:
826 This helps to keep old installed files (especially libraries)
827 from interfering with the new build.
828 To build to a DESTDIR with build.sh, use the "-D" option.
829 To build to a DESTDIR without using build.sh, set the DESTDIR
830 environment variable before running make build. It should be
831 set to the pathname of an initially empty directory.
832 Problems: if you do not use build.sh, you might need to
833 update critical utilities without using DESTDIR since
834 nothing is executed from what is installed in DESTDIR.
835 (See critical utils, below.)
836 Build often:
837 This keeps critical utilities current enough to not choke
838 on any other part of the source tree that depends on up to
839 date functionality. If you use build.sh, you should not have
840 this problem.
841
842 What to do if things don't work:
843 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
844 When things don't work there are usually a few things that commonly
845 should be done.
846 1) make includes
847 This should be done automatically by make build.
848 2) cd share/mk && make install
849 Again, automatically done by make build.
850
851 Failsafe rebuild of a small part of the tree:
852 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
853 To make sure you rebuild something correctly you want to do
854 something like the following:
855 1) Make sure the includes and .mk files are up to date.
856 2) Make sure any program used to build the particular
857 utility is up to date. (yacc, lex, etc...)
858 3) cd ...path/to/util...
859 make cleandir
860 rm ...all obj directories...
861 make cleandir # yes, again
862 make obj
863 make depend && make
864
865 Failsafe rebuild of the entire tree:
866 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
867 If you really want to make sure the source tree is clean and
868 ready for a build try the following. Note that sourcing /etc/mk.conf
869 (a make(1) Makefile) in this manner is not right, and will not work
870 for anyone who uses any make(1) features in /etc/mk.conf.
871

904
905 Other problems and possible solutions:
906 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
907 Symptom:Complaints involving a Makefile.
908 Fix: Rebuild usr.bin/make:
909 cd usr.bin/make && make && make install
910 Or, a failsafe method if that doesn't work:
911 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
912
913 Fix: Make sure .mk files are up to date.
914 cd share/mk && make install
915
916 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
917 Fix: Rebuild usr.bin/config
918
919 Symptom:
920 Fix: Rebuild usr.bin/yacc
921
922 Symptom:
923 Fix: Rebuild usr.bin/lex
924
925 Symptom:
926 Fix: rm /usr/lib/libbfd.a
927
928 Symptom:Obsolete intermediate files are used during compilation
929 Fix: Try the following sequence of commands in the directory in question.
930 make cleandir; rm `make print-objdir`; make cleandir; make obj
931 (If you built the tree without "make obj" in the past, obsolete files
932 may remain. The command tries to clean everything up)
933
934 Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible
935 pointer type
936 Fix: Rebuild and install usr.bin/menuc
937
938 Symptom:mklocale not found during build in share/locale/ctype
939 Fix: Build and install usr.bin/mklocale
940
941 Symptom:undefined reference to `__assert13' or `__unsetenv13'
942 Fix: Rebuild and install lib/libc
943
944 Symptom:usr.bin/config fails to build.
945 Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
946
947 Symptom:undefined reference to `getprogname' or `setprogname'
948 Fix: Rebuild and install lib/libc
949
950 Symptom:lint does not understand the '-X' option
951 Fix: May need to build & install libs with NOLINT=1 before rebuilding lint
952
953 Symptom:Update build fails in src/tools/gcc complaining that a variable
954 (e.g. CPPFLAGS) has changed since the previous run.
955 Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
956
957 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
958 No such file or directory.
959 Cause: If a directory is created by mistake, then it is sometimes
960 deleted from the CVS repository using administrative commands
961 that bypass the normal cvs access controls. If your cvs working tree
962 contains references to a directory that has been deleted on the
963 server in this way, then "cvs update" reports this error.
964 Fix: Recursively delete the affected directory from your working tree
965 and try the update again.
966
