UPDATING revision 1.377 1 $NetBSD: UPDATING,v 1.377 2025/04/13 17:23:06 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.
13
14 Sections are marked with "^^^^^". After the section on "Recent changes"
15 are several sections containing more general information.

19 Recent changes:
20 ^^^^^^^^^^^^^^^
21
22 20250413:
23 A change to bsd.lib.mk requires a clean build of all libraries.
24
25 20250131:
26 The switch to the new jemalloc requires cleaning in libc.
27
28 20241122:
29 Changes to various libraries' build options require cleaning
30 their objdirs in update builds:
31
32 cd external/bsd/file/lib && $TOOLDIR/bin/nbmake-$ARCH clean
33 cd external/bsd/libarchive/lib && $TOOLDIR/bin/nbmake-$ARCH clean
34 cd external/public-domain/xz/lib && $TOOLDIR/bin/nbmake-$ARCH clean
35
36 Also, for architectures with MKCOMPAT, it is necessary to clean
37 the compat objdirs too. The easiest way is:
38
39 rm -rf OBJDIR/compat/*/*/external/bsd/file/lib
40 rm -rf OBJDIR/compat/*/*/external/bsd/libarchive/lib
41 rm -rf OBJDIR/compat/*/*/external/public-domain/xz/lib
42
43 Changes to bsd.lib.mk to improve detecting differences in
44 shared library symbol exports may cause some .actsym files in
45 the objdir to become stale in update builds.
46
47 To work around this, delete all files matching `*.actsym' in
48 the objdir. For example:
49
50 find OBJDIR -name '*.actsym' -type f -print0 | xargs -0 rm
51
52 20241104:
53 Changes around the integration of the zstd compression
54 library may require manual deletion of some object directories
55 if you update from a build from a few days ago:
56 rm -rf DESTDIR/usr/lib/*/libarchive*
57 rm -rf DESTDIR/usr/lib/*/libmagic*
58 rm -rf DESTDIR/usr/lib/*/libzstd*
59 rm -rf DESTDIR/usr/lib/libarchive*
60 rm -rf DESTDIR/usr/lib/libmagic*
61 rm -rf DESTDIR/usr/lib/libzstd*
62 rm -rf OBJDIR/compat/*/*/external/bsd/file/
63 rm -rf OBJDIR/compat/*/*/external/bsd/libarchive/
64 rm -rf OBJDIR/compat/*/*/external/bsd/zstd/
65 rm -rf OBJDIR/external/bsd/file/
66 rm -rf OBJDIR/external/bsd/libarchive/
67 rm -rf OBJDIR/external/bsd/zstd/
68 rm -rf OBJDIR/external/gpl3/gcc/
69 rm -rf OBJDIR/tools/gcc/
70
71 20240926:
72 Building -current when running on amd64 from about 20240924
73 to about 20240926 will not work due to a "malloc_np.h"
74 error. Please downgrade to a version from 20240924 or older,
75 or upgrade to a newer version e.g. using a binary release from
76 the NetBSD build servers.
77
78 20240923:
79 Update builds will require cleaning the object directories for
80 jemalloc (like: "rm -rf $OBJ/external/bsd/jemalloc*") and the
81 libc dependency files (like: "rm $OBJ/lib/libc/jemalloc.*").
82 On architectures with COMPAT libs, those also have to be cleaned,
83 e.g. on sparc64: "rm -rf $OBJ/compat/sparc64/sparc/external/bsd/jemalloc*"
84 and "rm $OBJ/compat/sparc64/sparc/lib/libc/jemalloc.*".
85
86 20240817:
87 Update builds will require cleaning in src/external/historical/nawk/bin
88 in order to remove the awk binary since now there is a subdirectory
89 called awk.
90
91 20240812:
92 Update builds will require removing the tools objdir for gdb
93 if building with MKCROSSGDB=yes. All architectures use gdb.old
94 now.
95
96 20240630:
97 Update builds will require removing the tools objdir for binutils
98 (as most architectures should use binutils.old now).
99
100 20240610:
101 Update builds are likely to require removing the objdir for
102 distrib/<arch>/cdroms - or at least references to libarchive
103 from within there after the recent libarchive update.
104
105 20240504:
106 Update builds on x86 require making the `cleandir' target in
107 lib/libm, or deleting the objdir for lib/libm.
108
109 20240423:
110 Update builds with x11 may fail after switching to Mesa 21.
111
112 20240410:
113 Update builds may require manually deleting
114 $DESTDIR/var/run/named (and, potentially,
115 $DESTDIR/var/run/lwresd) in order to avoid checkflist failure.
116
117 20240409:
118 32-bit compatibility libraries were moved into the base32
119 and debug32 sets. HTML man pages were moved into the manhtml set.
120
121 20230828:
122 If:
123 - you updated to current and ran postinstall between 20230826
124 and 20230828 inclusive, and
125 - you are not using anything outside the base system to
126 populate /etc/openssl/certs (e.g., manually adding
127 certificates or using ca-certificates or mozilla-rootcerts or
128 mozilla-rootcerts-openssl from pkgsrc),
129 delete /etc/openssl/certs and rerun postinstall or just
130 `certctl rehash'.
131
132 Otherwise, certctl(8) will think someone else has left
133 /etc/openssl/certs in the way and will avoid clobbering it on
134 upgrade from older NetBSD.
135
136 20230718:
137 build.sh will use mk.conf in the same directory as build.sh instead
138 of /etc/mk.conf, unless MAKECONF is already defined in the environment.
139
140 20230714:
141 Import of gcc 10.5 requires a clean build of at least tools/gcc
142 and external/gpl3/gcc* object directories. An update build
143 without cleaning will result in obscure failures in rare corner
144 cases.
145
146 20230604:
147 Building native kernels with the installed make(1) instead of
148 the $TOOLDIR/bin/nbmake-${arch} wrapper will fail if userland
149 has not been updated. Note that this is an unsupported build
150 configuration (but usually works if userland is -current enough).
151
152 20230523:
153 ctfmerge was fixed as macOS host tool. This may require a clean tools
154 rebuild to detect the update to tools/compat/configure.
155
156 20230515:
157 New openssl build requires removal of the crypto/external/bsd/openssl
158 and tests/crypto/libcrypto subdirectories in the ${OBJDIR} hierarchy.
159 Otherwise test results may be wrong due to wrong "golden" output
160 files being installed.
161
162 20230322:
163 Fixes for moved /lib/libisns* mean that builds will complain about
164 ./usr/lib/libisns* being missing until src/lib/libisns is forced
165 to (re)install the files, including the symlinks. The simplest
166 way is to clean this subdir before building.
167
168 20230112:
169 New binutils require an updated ld.elf_so. If you are doing
170 (unsupported) in-place self builds (with the -E flag to build.sh),
171 make sure to have installed latest ld.elf_so before you rebuild
172 userland.
173
174 20221116:
175 The addition to NetBSD's version of UFS2 of support for extended
176 attributes broke backward compatibility with previous releases
177 of NetBSD, so UFS2 has been restored to being compatible with
178 previous NetBSD releases by disabling extended attributes.
179 (Note that ACLs are implemented as extended attributes, so
180 this changes disables ACLs as well.)
181
182 Support for UFS2 with extended attributes is now available in a new
183 UFS variant called UFS2ea. If you have created extended attributes
184 in an original UFS2 file system then "fsck -p" will now fail due to
185 the unexpected presence of extended attributes and "fsck -y" will
186 remove all extended attributes. If you wish to preserve extended
187 attributes rather than delete them, there is a utility to convert
188 a UFS2 file system to UFS2ea and leave extended attributes in place,
189 but this should be used with caution since it will preserve any
190 extended attributes that have been corrupted by the backward
191 incompatibility too.
192
193 If you wish to use a UFS2ea file system as your root file system,
194 then you will need to update your boot loader to a version that
195 supports UFS2ea.
196
197 For more information, see:
198 https://wiki.netbsd.org/features/UFS2ea
199
200 20221111:
201 The new libdrm import worsened the conflict issues for the
202 kdump/ktruss ioctl, and i915 now conflicts with base, and has
203 been turned off. This will cause update build issues like:
204
205 kdump-ioctl.c:12175:143: error: 'DRM_IOCTL_I915_DESTROY_HEAP'
206 undeclared here (not in a function);
207 did you mean 'DRM_IOCTL_MODE_DESTROY_DUMB'?
208
209 You'll need to clean usr.bin/ktruss, usr.bin/kdump, and rescue.
210
211 20220921:
212 Since the kernel version was bumped to 9.99.100, the bootloader
213 must be updated on x86 or EFI boot platforms in order to load
214 modules from boot.cfg(5) or interactively at the bootloader
215 prompt.
216
217 The kernel can still load modules at runtime, with modload(8)
218 or modules.conf(5), with no bootloader update. This will not
219 affect release branches because it only applies to patch
220 numbers >=100.
221
222 On x86 (i386 or amd64) with BIOS boot, this requires copying a
223 new /usr/mdec/boot to /boot. You can build this in the destdir
224 by running `$TOOLDIR/bin/nbmake-$ARCH dependall install' in
225 sys/arch/i386/stand.
226
227 On platforms with EFI boot (including x86 with EFI boot), this
228 requires copying a new /usr/mdec/boot*.efi to the EFI/BOOT/
229 directory on the EFI system partition. The boot*.efi file is:
230
231 aarch64 bootaa64.efi
232 amd64 bootx64.efi
233 arm bootarm.efi (32-bit arm)
234 i386 bootx32.efi
235
236 You can build this in the destdir by running
237 `$TOOLDIR/bin/nbmake-$ARCH dependall install' in
238 sys/stand/efiboot/boot*.
239
240 20220821:
241 Support for building extsrc/ has been deprecated.
242 EXTSRCSRCDIR and MKEXTSRC have been deprecated.
243
244 20220714:
245 Updates to xorg-server and associated drivers may cause builds to
246 fail. Cleaning both DESTDIR and the xorg build tree may be needed.
247
248 20220628:
249 Changes in the build of src/games/robots require a clean build
250 of that program.
251
252 20211116:
253 Changes in the xorg build require clean obj dirs for external/mit/xorg
254 (or a full clean/non-update build).
255
256 20211112:
257 Device tree sources were updated for evbarm. Some device nodes
258 (in particular, ld(4) devices on the ROCKPro64) will be renumbered.
259
260 20211014:
261 MKPIE default for aarch64 has changed, a clean build is required.
262
263 20210917:
264 Changed MNT_ACLS to default to POSIX1e ACLs instead of NFSv4
265 ACLs, to be compatible with FreeBSD. If you are using NFSv4 ACLs
266 and have "acls" in /etc/fstab you'll need to change it to "nfs4acls".
267
268 20210711:
269 Updated GMP sources may require cleaning in tools/gmp and/or in
270 external/lgpl3/gmp/lib, particularly if GCC itself does not build.
271
272 20210417:
273 GCC 10 was enabled for several platforms. If builds fail in either
274 tools/gcc or external/gpl3/gcc, first try cleaning those objects and
275 removing the $DESTDIR/usr/include/g++ subdirectory.
276
277 20201016:
278 MIPS kernel modules have been disabled until they work. This will
279 turn up in extra files in the DESTDIR, which should be cleaned.
280
281 20200925:
282 GNU MPC and MPFR have been updated. At least MPFR needs cleaning
283 in both the tools and external dirs.
284
285 20200912:
286 GCC 9 has arrived for Arm and x86 platforms, and will be coming
287 for several more, as will binutils 2.34. Clean as required.
288
289 20200907:
290 GCC 9 is coming, and binutils has been updated for MIPS. This
291 probably requires cleaning the tools/binutils.
292
293 20200811:
294 GCC updates may require cleaning the objdir. This may occur
295 due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming
296 GCC 9 upgrade.
297
298 20200614:
299 blacklist* has been renamed to blocklist*. postinstall(8)
300 should handle the migration.
301
302 20200601:
303 Due to a mistake in LIBISPRIVATE handling, .so libraries were
304 created in the build directories and need cleaning.
305
306 20200311:
307 GCC 8 ports will need cleaning in src/tools/gcc and
308 src/external/gpl3/gcc due to GCC 8.4 update.
309
310 20191118:
311 More architectures were switched to gcc8:
312 i386, ia64 powerpc64, sparc, sparc64, arm
313 The same comments as in 20191022 apply.
314
315 20191112:
316 The LLVM update requires a clean rebuild for all architectures using
317 LLVM during the tools build phase (i386, amd64, aarch64).
318
319 20191022:
320 Ports amd64 and aarch64 switched to GCC 8.3 by default.
321 In-place ("expert mode", build.sh -E) builds are not supported
322 when going from a GCC 7 userland to GCC 8. Do a regular
323 build to a different DESTDIR (or preferably: build.sh -U) at least
324 once and install sets, or download comp.{tar.xz,tgz} from the
325 daily builds and install that before doing the next in-place build.
326
327 20191001:
328 GCC 8.3 was imported. Builds of src/tools/gcc may fail if
329 old builds with GCC 7 output now uses GCC 8. Clean this
330 directory, and also clean src/external/gpl3/gcc.
331
332 20190903:
333 Files with names that coincide with existing files' names on
334 case-insensitive file systems were inadvertently committed, for
335 radeon GPU firmware. We cannot mark these as obsolete for
336 postinstall to fix, so if you updated src since 2019-08-26, and
337 ran build.sh distribution or ran build.sh release, you must
338 manually delete the following files in your DESTDIR (which is
339 usually $OBJDIR/destir.$ARCH), or from / if you have installed
340 them:

410 later.
411
412 20190727:
413 The uefi bootloader has gained tftp support and needs a clean
414 build. If you do update builds, manually clean its object
415 directory by something like:
416 cd sys/arch/i386/stand/efiboot && make clean
417
418 20190723:
419 The jemalloc allocator in libc is now built without extended
420 debugging (for performance reasons). In update builds make sure
421 to rebuild it completely, by removing all affected object files,
422 including compat builds, something like:
423 cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
424
425 20190207:
426 GCC 7 switched for many ports. Update builds are likely to fail.
427
428 Hints for a more successful build:
429 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
430 Use build.sh, but do not use its "expert mode":
431 This will automatically build the tools in the
432 correct order, and it will keep the tools and the
433 new build products from interfering with the running
434 system. This will allow you to ignore most of the
435 other advice in this file.
436 Build a new kernel first:
437 This makes sure that any new system calls or features
438 expected by the new userland will be present. This
439 helps to avoid critical errors when upgrading.
440 Use object directories:
441 This helps to keep stale object
442 files from polluting the build if a Makefile "forgets"
443 about one. It also makes it easier to clean up after
444 a build. It's also necessary if you want to use the
445 same source tree for multiple machines.
446 To use object directories with build.sh:
447 a) invoke build.sh with the "-M" or "-O" options.
448 To use object directories without using build.sh:
449 a) cd /usr/src ; make cleandir
450 b) Add "OBJMACHINE=yes" to /etc/mk.conf
451 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
452 d) cd /usr/src ; make build
453 Note that running "make obj" in a directory will create
454 in obj.$MACHINE directory.
455 Build to a DESTDIR:
456 This helps to keep old installed files (especially libraries)
457 from interfering with the new build.
458 To build to a DESTDIR with build.sh, use the "-D" option.
459 To build to a DESTDIR without using build.sh, set the DESTDIR
460 environment variable before running make build. It should be
461 set to the pathname of an initially empty directory.
462 Problems: if you do not use build.sh, you might need to
463 update critical utilities without using DESTDIR since
464 nothing is executed from what is installed in DESTDIR.
465 (See critical utils, below.)
466 Build often:
467 This keeps critical utilities current enough to not choke
468 on any other part of the source tree that depends on up to
469 date functionality. If you use build.sh, you should not have
470 this problem.
471
472 What to do if things don't work:
473 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
474 When things don't work there are usually a few things that commonly
475 should be done.
476 1) make includes
477 This should be done automatically by make build.
478 2) cd share/mk && make install
479 Again, automatically done by make build.
480
481 Failsafe rebuild of a small part of the tree:
482 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
483 To make sure you rebuild something correctly you want to do
484 something like the following:
485 1) Make sure the includes and .mk files are up to date.
486 2) Make sure any program used to build the particular
487 utility is up to date. (yacc, lex, etc...)
488 3) cd ...path/to/util...
489 make cleandir

495 Failsafe rebuild of the entire tree:
496 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
497 If you really want to make sure the source tree is clean and
498 ready for a build try the following. Note that sourcing /etc/mk.conf
499 (a make(1) Makefile) in this manner is not right, and will not work
500 for anyone who uses any make(1) features in /etc/mk.conf.

534 Other problems and possible solutions:
535 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
536 Symptom:Complaints involving a Makefile.
537 Fix: Rebuild usr.bin/make:
538 cd usr.bin/make && make && make install
539 Or, a failsafe method if that doesn't work:
540 cd usr.bin/make && cc -DMAKE_NATIVE *.c -I. -o make \
541 && install make /usr/bin
542
543 Fix: Make sure .mk files are up to date.
544 cd share/mk && make install
545
546 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
547 Fix: Rebuild usr.bin/config
548
549 Symptom:Obsolete intermediate files are used during compilation
550 Fix: Try the following sequence of commands in the directory in question.
551 make cleandir; rm `make print-objdir`; make cleandir; make obj
552 (If you built the tree without "make obj" in the past, obsolete files
553 may remain. The command tries to clean everything up)
554
555 Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible
556 pointer type
557 Fix: Rebuild and install usr.bin/menuc
558
559 Symptom:mklocale not found during build in share/locale/ctype
560 Fix: Build and install usr.bin/mklocale
561
562 Symptom:undefined reference to `__assert13' or `__unsetenv13'
563 Fix: Rebuild and install lib/libc
564
565 Symptom:usr.bin/config fails to build.
566 Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
567
568 Symptom:undefined reference to `getprogname' or `setprogname'
569 Fix: Rebuild and install lib/libc
570
571 Symptom:Update build fails in src/tools/gcc complaining that a variable
572 (e.g. CPPFLAGS) has changed since the previous run.
573 Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
574
575 Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
576 No such file or directory.
577 Cause: If a directory is created by mistake, then it is sometimes
578 deleted from the CVS repository using administrative commands
579 that bypass the normal cvs access controls. If your cvs working tree
580 contains references to a directory that has been deleted on the
581 server in this way, then "cvs update" reports this error.
582 Fix: Recursively delete the affected directory from your working tree
583 and try the update again.
