UPDATING revision 1.386
1$NetBSD: UPDATING,v 1.386 2025/11/03 18:09:01 martin Exp $

3This file (UPDATING) is intended to be a brief reference to recent
4changes that might cause problems in the build process, and a guide for
5what to do if something doesn't work.
6
7For a more detailed description of the recommended way to build NetBSD
8using build.sh, see the BUILDING file.
9
10Note that much of the advice in this UPDATING file was written before
11build.sh existed.  Nevertheless, the advice here may be useful for
12working around specific problems with build.sh.
13
14Sections are marked with "^^^^^".  After the section on "Recent changes"
15are several sections containing more general information.
16
17See also: BUILDING, build.sh, Makefile.

19Recent changes:
20^^^^^^^^^^^^^^^
21
2220251028:
23	libpthread had it's shared library version go back (from 1.7 to
24	1.6). This may cause fallout during update builds, remove the
25	libpthread obj dir and all libpthread.so.1.7\* files in the
26	dest dir.
27	If you have build other software/packages on a -current system
28	from 20251026 or 20251027 you need to rebuild them after
29	updating your base system again.
30
3120251019:
32	Changes to how libcrypto got linked (libpthread not required
33	any more) cause failures in update builds. To fix, run
34	(as your build user) a "make cleandir" in the following
35	subdirectories:
36
37	crypto/external/apache2/openssl
38	crypto/external/bsd/heimdal
39	crypto/external/bsd/netpgp
40	crypto/external/bsd/openssh
41	external/bsd/libfido2
42	external/bsd/nsd
43	external/bsd/ntp
44	external/bsd/pam-u2f
45	external/bsd/ppp
46	external/bsd/tcpdump
47	external/bsd/wpa
48	games/factor
49	libexec/httpd
50	tests/crypto/libcrypto
51	tests/lib/libc/hash
52	usr.bin/dc
53	usr.bin/ftp
54	usr.bin/moduli
55	usr.bin/nbsvtool
56	usr.sbin/plainrsa-gen
57	usr.sbin/syslogd
58
5920250721:
60	GCC 12.5 was imported and there may be weird build issues.
61	Clean any GCC build dirs if you encounter weird things.
62
6320250720:
64	New openssl and old objects for tests for libcrypto may
65	cause spurious test failure, clean the src/tests/crypto/libcrypto
66	object dirs.
67
6820250528:
69	Changes in the tools build require removing all config.cache
70	files in the object tools directories.
71
7220250427:
73	The KERNEL_DIR option to build.sh is now functional.  Set it
74	with ``-V KERNEL_DIR=yes'' on your build.sh command.
75	With this, you can now colocate kernel and associated modules
76	in /netbsd/{kernel,kernel.dbg,modules} instead of having the
77	kernel in / but modules in /stand.
78
79	Note that you'll need new bootstrap code to use this feature.
80
81	This completes work begun many years ago by christos@ :-)
82
8320250413:
84	A change to bsd.lib.mk requires a clean build of all libraries.
85
8620250131:
87	The switch to the new jemalloc requires cleaning in libc.
88
8920241122:
90	Changes to various libraries' build options require cleaning
91	their objdirs in update builds:
92
93	cd external/bsd/file/lib && $TOOLDIR/bin/nbmake-$ARCH clean
94	cd external/bsd/libarchive/lib && $TOOLDIR/bin/nbmake-$ARCH clean
95	cd external/public-domain/xz/lib && $TOOLDIR/bin/nbmake-$ARCH clean
96
97	Also, for architectures with MKCOMPAT, it is necessary to clean
98	the compat objdirs too.  The easiest way is:
99
100	rm -rf OBJDIR/compat/*/*/external/bsd/file/lib
101	rm -rf OBJDIR/compat/*/*/external/bsd/libarchive/lib
102	rm -rf OBJDIR/compat/*/*/external/public-domain/xz/lib
103
104	Changes to bsd.lib.mk to improve detecting differences in
105	shared library symbol exports may cause some .actsym files in
106	the objdir to become stale in update builds.
107
108	To work around this, delete all files matching `*.actsym' in
109	the objdir.  For example:
110
111	find OBJDIR -name '*.actsym' -type f -print0 | xargs -0 rm
112
11320241104:
114	Changes around the integration of the zstd compression
115	library may require manual deletion of some object directories
116	if you update from a build from a few days ago:
117	rm -rf DESTDIR/usr/lib/*/libarchive*
118	rm -rf DESTDIR/usr/lib/*/libmagic*
119	rm -rf DESTDIR/usr/lib/*/libzstd*
120	rm -rf DESTDIR/usr/lib/libarchive*
121	rm -rf DESTDIR/usr/lib/libmagic*
122	rm -rf DESTDIR/usr/lib/libzstd*
123	rm -rf OBJDIR/compat/*/*/external/bsd/file/
124	rm -rf OBJDIR/compat/*/*/external/bsd/libarchive/
125	rm -rf OBJDIR/compat/*/*/external/bsd/zstd/
126	rm -rf OBJDIR/external/bsd/file/
127	rm -rf OBJDIR/external/bsd/libarchive/
128	rm -rf OBJDIR/external/bsd/zstd/
129	rm -rf OBJDIR/external/gpl3/gcc/
130	rm -rf OBJDIR/tools/gcc/
131
13220240926:
133	Building -current when running on amd64 from about 20240924
134	to about 20240926 will not work due to a "malloc_np.h"
135	error. Please downgrade to a version from 20240924 or older,
136	or upgrade to a newer version e.g. using a binary release from
137	the NetBSD build servers.
138
13920240923:
140	Update builds will require cleaning the object directories for
141	jemalloc (like: "rm -rf $OBJ/external/bsd/jemalloc*") and the
142	libc dependency files (like: "rm $OBJ/lib/libc/jemalloc.*").
143	On architectures with COMPAT libs, those also have to be cleaned,
144	e.g. on sparc64: "rm -rf $OBJ/compat/sparc64/sparc/external/bsd/jemalloc*"
145	and "rm $OBJ/compat/sparc64/sparc/lib/libc/jemalloc.*".
146
14720240920:
148	Update builds will require cleaning in src/external/historical/nawk/bin
149	in order to remove the awk subdirectory since there is now a binary
150	called awk.
151
15220240817:
153	Update builds will require cleaning in src/external/historical/nawk/bin
154	in order to remove the awk binary since now there is a subdirectory
155	called awk.
156
15720240812:
158	Update builds will require removing the tools objdir for gdb
159	if building with MKCROSSGDB=yes. All architectures use gdb.old
160	now.
161
16220240630:
163	Update builds will require removing the tools objdir for binutils
164	(as most architectures should use binutils.old now).
165
16620240610:
167	Update builds are likely to require removing the objdir for
168	distrib/<arch>/cdroms - or at least references to libarchive
169	from within there after the recent libarchive update.
170
17120240504:
172	Update builds on x86 require making the `cleandir' target in
173	lib/libm, or deleting the objdir for lib/libm.
174
17520240423:
176	Update builds with x11 may fail after switching to Mesa 21.
177
17820240410:
179	Update builds may require manually deleting
180	$DESTDIR/var/run/named (and, potentially,
181	$DESTDIR/var/run/lwresd) in order to avoid checkflist failure.
182
18320240409:
184	32-bit compatibility libraries were moved into the base32
185	and debug32 sets.  HTML man pages were moved into the manhtml set.
186
18720230828:
188	If:
189        - you updated to current and ran postinstall between 20230826
190	  and 20230828 inclusive, and
191        - you are not using anything outside the base system to
192	  populate /etc/openssl/certs (e.g., manually adding
193	  certificates or using ca-certificates or mozilla-rootcerts or
194	  mozilla-rootcerts-openssl from pkgsrc),
195	delete /etc/openssl/certs and rerun postinstall or just
196	`certctl rehash'.
197
198	Otherwise, certctl(8) will think someone else has left
199	/etc/openssl/certs in the way and will avoid clobbering it on
200	upgrade from older NetBSD.
201
20220230718:
203	build.sh will use mk.conf in the same directory as build.sh instead
204	of /etc/mk.conf, unless MAKECONF is already defined in the environment.
205
20620230714:
207	Import of gcc 10.5 requires a clean build of at least tools/gcc
208	and external/gpl3/gcc* object directories. An update build
209	without cleaning will result in obscure failures in rare corner
210	cases.
211
21220230604:
213	Building native kernels with the installed make(1) instead of
214	the $TOOLDIR/bin/nbmake-${arch} wrapper will fail if userland
215	has not been updated. Note that this is an unsupported build
216	configuration (but usually works if userland is -current enough).
217
21820230523:
219	ctfmerge was fixed as macOS host tool. This may require a clean tools
220	rebuild to detect the update to tools/compat/configure.
221
22220230515:
223	New openssl build requires removal of the crypto/external/bsd/openssl
224	and tests/crypto/libcrypto subdirectories in the ${OBJDIR} hierarchy.
225	Otherwise test results may be wrong due to wrong "golden" output
226	files being installed.
227
22820230322:
229	Fixes for moved /lib/libisns* mean that builds will complain about
230	./usr/lib/libisns* being missing until src/lib/libisns is forced
231	to (re)install the files, including the symlinks.  The simplest
232	way is to clean this subdir before building.
233
23420230112:
235	New binutils require an updated ld.elf_so. If you are doing
236	(unsupported) in-place self builds (with the -E flag to build.sh),
237	make sure to have installed latest ld.elf_so before you rebuild
238	userland.
239
24020221116:
241	The addition to NetBSD's version of UFS2 of support for extended
242	attributes broke backward compatibility with previous releases
243	of NetBSD, so UFS2 has been restored to being compatible with
244	previous NetBSD releases by disabling extended attributes.
245	(Note that ACLs are implemented as extended attributes, so
246	this changes disables ACLs as well.)
247
248	Support for UFS2 with extended attributes is now available in a new
249	UFS variant called UFS2ea.  If you have created extended attributes
250	in an original UFS2 file system then "fsck -p" will now fail due to
251	the unexpected presence of extended attributes and "fsck -y" will
252	remove all extended attributes.  If you wish to preserve extended
253	attributes rather than delete them, there is a utility to convert
254	a UFS2 file system to UFS2ea and leave extended attributes in place,
255	but this should be used with caution since it will preserve any
256	extended attributes that have been corrupted by the backward
257	incompatibility too.
258
259	If you wish to use a UFS2ea file system as your root file system,
260	then you will need to update your boot loader to a version that
261	supports UFS2ea.
262
263	For more information, see:
264	https://wiki.netbsd.org/features/UFS2ea
265
26620221111:
267	The new libdrm import worsened the conflict issues for the
268	kdump/ktruss ioctl, and i915 now conflicts with base, and has
269	been turned off.  This will cause update build issues like:
270
271		kdump-ioctl.c:12175:143: error: 'DRM_IOCTL_I915_DESTROY_HEAP'
272		   undeclared here (not in a function);
273		   did you mean 'DRM_IOCTL_MODE_DESTROY_DUMB'?
274
275	You'll need to clean usr.bin/ktruss, usr.bin/kdump, and rescue.
276
27720220921:
278	Since the kernel version was bumped to 9.99.100, the bootloader
279	must be updated on x86 or EFI boot platforms in order to load
280	modules from boot.cfg(5) or interactively at the bootloader
281	prompt.
282
283	The kernel can still load modules at runtime, with modload(8)
284	or modules.conf(5), with no bootloader update.  This will not
285	affect release branches because it only applies to patch
286	numbers >=100.
287
288	On x86 (i386 or amd64) with BIOS boot, this requires copying a
289	new /usr/mdec/boot to /boot.  You can build this in the destdir
290	by running `$TOOLDIR/bin/nbmake-$ARCH dependall install' in
291	sys/arch/i386/stand.
292
293	On platforms with EFI boot (including x86 with EFI boot), this
294	requires copying a new /usr/mdec/boot*.efi to the EFI/BOOT/
295	directory on the EFI system partition.  The boot*.efi file is:
296
297	aarch64	bootaa64.efi
298	amd64	bootx64.efi
299	arm	bootarm.efi	(32-bit arm)
300	i386	bootx32.efi
301
302	You can build this in the destdir by running
303	`$TOOLDIR/bin/nbmake-$ARCH dependall install' in
304	sys/stand/efiboot/boot*.
305
30620220821:
307	Support for building extsrc/ has been deprecated.
308	EXTSRCSRCDIR and MKEXTSRC have been deprecated.
309
31020220714:
311	Updates to xorg-server and associated drivers may cause builds to
312	fail.  Cleaning both DESTDIR and the xorg build tree may be needed.
313
31420220628:
315	Changes in the build of src/games/robots require a clean build
316	of that program.
317
31820211116:
319	Changes in the xorg build require clean obj dirs for external/mit/xorg
320	(or a full clean/non-update build).
321
32220211112:
323	Device tree sources were updated for evbarm.  Some device nodes
324	(in particular, ld(4) devices on the ROCKPro64) will be renumbered.
325
32620211014:
327	MKPIE default for aarch64 has changed, a clean build is required.
328
32920210917:
330	Changed MNT_ACLS to default to POSIX1e ACLs instead of NFSv4
331	ACLs, to be compatible with FreeBSD. If you are using NFSv4 ACLs
332	and have "acls" in /etc/fstab you'll need to change it to "nfs4acls".
333
33420210711:
335	Updated GMP sources may require cleaning in tools/gmp and/or in
336	external/lgpl3/gmp/lib, particularly if GCC itself does not build.
337
33820210417:
339	GCC 10 was enabled for several platforms.  If builds fail in either
340	tools/gcc or external/gpl3/gcc, first try cleaning those objects and
341	removing the $DESTDIR/usr/include/g++ subdirectory.
342
34320201016:
344	MIPS kernel modules have been disabled until they work.  This will
345	turn up in extra files in the DESTDIR, which should be cleaned.
346
34720200925:
348	GNU MPC and MPFR have been updated.  At least MPFR needs cleaning
349	in both the tools and external dirs.
350
35120200912:
352	GCC 9 has arrived for Arm and x86 platforms, and will be coming
353	for several more, as will binutils 2.34.  Clean as required.
354
35520200907:
356	GCC 9 is coming, and binutils has been updated for MIPS.  This
357	probably requires cleaning the tools/binutils.
358
35920200811:
360	GCC updates may require cleaning the objdir.  This may occur
361	due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming
362	GCC 9 upgrade.
363
36420200614:
365	blacklist* has been renamed to blocklist*. postinstall(8)
366	should handle the migration.
367
36820200601:
369	Due to a mistake in LIBISPRIVATE handling, .so libraries were
370	created in the build directories and need cleaning.
371
37220200311:
373	GCC 8 ports will need cleaning in src/tools/gcc and
374	src/external/gpl3/gcc due to GCC 8.4 update.
375
37620191118:
377	More architectures were switched to gcc8:
378	    i386, ia64 powerpc64, sparc, sparc64, arm
379	The same comments as in 20191022 apply.
380
38120191112:
382	The LLVM update requires a clean rebuild for all architectures using
383	LLVM during the tools build phase (i386, amd64, aarch64).
384
38520191022:
386	Ports amd64 and aarch64 switched to GCC 8.3 by default.
387	In-place ("expert mode", build.sh -E) builds are not supported
388	when going from a GCC 7 userland to GCC 8. Do a regular
389	build to a different DESTDIR (or preferably: build.sh -U) at least
390	once and install sets, or download comp.{tar.xz,tgz} from the
391	daily builds and install that before doing the next in-place build.
392
39320191001:
394	GCC 8.3 was imported.  Builds of src/tools/gcc may fail if
395	old builds with GCC 7 output now uses GCC 8.  Clean this
396	directory, and also clean src/external/gpl3/gcc.
397
39820190903:
399	Files with names that coincide with existing files' names on
400	case-insensitive file systems were inadvertently committed, for
401	radeon GPU firmware.  We cannot mark these as obsolete for
402	postinstall to fix, so if you updated src since 2019-08-26, and
403	ran build.sh distribution or ran build.sh release, you must
404	manually delete the following files in your DESTDIR (which is
405	usually $OBJDIR/destir.$ARCH), or from / if you have installed
406	them:

47820190727:
479	The uefi bootloader has gained tftp support and needs a clean
480	build. If you do update builds, manually clean its object
481	directory by something like:
482	cd sys/arch/i386/stand/efiboot && make clean
483
48420190723:
485	The jemalloc allocator in libc is now built without extended
486	debugging (for performance reasons). In update builds make sure
487	to rebuild it completely, by removing all affected object files,
488	including compat builds, something like:
489	cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
490
49120190207:
492	GCC 7 switched for many ports.  Update builds are likely to fail.
493
494Hints for a more successful build:
495^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
496    Use build.sh, but do not use its "expert mode":
497	This will automatically build the tools in the
498	   correct order, and it will keep the tools and the
499	   new build products from interfering with the running
500	   system.  This will allow you to ignore most of the
501	   other advice in this file.
502    Build a new kernel first:
503	This makes sure that any new system calls or features
504	   expected by the new userland will be present.  This
505	   helps to avoid critical errors when upgrading.
506    Use object directories:
507	This helps to keep stale object
508	   files from polluting the build if a Makefile "forgets"
509	   about one.  It also makes it easier to clean up after
510	   a build.  It's also necessary if you want to use the
511	   same source tree for multiple machines.
512	   To use object directories with build.sh:
513	    a) invoke build.sh with the "-M" or "-O" options.
514	   To use object directories without using build.sh:
515	    a) cd /usr/src ; make cleandir
516	    b) Add "OBJMACHINE=yes" to /etc/mk.conf
517	    c) Add "MKOBJDIRS=yes" to /etc/mk.conf
518	    d) cd /usr/src ; make build
519	   Note that running "make obj" in a directory will create
520	   in obj.$MACHINE directory.
521    Build to a DESTDIR:
522	This helps to keep old installed files (especially libraries)
523	   from interfering with the new build.
524	   To build to a DESTDIR with build.sh, use the "-D" option.
525	   To build to a DESTDIR without using build.sh, set the DESTDIR
526	   environment variable before running make build.  It should be
527	   set to the pathname of an initially empty directory.
528	   Problems: if you do not use build.sh, you might need to
529		update critical utilities without using DESTDIR since
530		nothing is executed from what is installed in DESTDIR.
531		(See critical utils, below.)
532    Build often:
533	This keeps critical utilities current enough to not choke
534	on any other part of the source tree that depends on up to
535	date functionality.  If you use build.sh, you should not have
536	this problem.
537
538What to do if things don't work:
539^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
540When things don't work there are usually a few things that commonly
541should be done.
542    1)	make includes
543	This should be done automatically by make build.
544    2)  cd share/mk && make install
545	Again, automatically done by make build.
546
547Failsafe rebuild of a small part of the tree:
548^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
549To make sure you rebuild something correctly you want to do
550something like the following:
551    1)  Make sure the includes and .mk files are up to date.
552    2)  Make sure any program used to build the particular
553	utility is up to date.  (yacc, lex, etc...)
554    3)  cd ...path/to/util...
555	make cleandir
556	rm ...all obj directories...
557	make cleandir			# yes, again
558	make obj
559	make depend && make
560
561Failsafe rebuild of the entire tree:
562^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
563If you really want to make sure the source tree is clean and
564ready for a build try the following.  Note that sourcing /etc/mk.conf
565(a make(1) Makefile) in this manner is not right, and will not work
566for anyone who uses any make(1) features in /etc/mk.conf.
567
568---cut here---

577    exit 1

595	usr.bin/yacc
596	usr.bin/lex
597	usr.bin/xlint
598	usr.bin/config
599
600Other problems and possible solutions:
601^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
602Symptom:Complaints involving a Makefile.
603Fix:	Rebuild usr.bin/make:
604	cd usr.bin/make && make && make install
605	Or, a failsafe method if that doesn't work:
606	cd usr.bin/make && cc -DMAKE_NATIVE *.c -I. -o make \
607	&& install make /usr/bin
608
609Fix:	Make sure .mk files are up to date.
610	cd share/mk && make install
611
612Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
613Fix:	Rebuild usr.bin/config
614
615Symptom:Obsolete intermediate files are used during compilation
616Fix:	Try the following sequence of commands in the directory in question.
617	make cleandir; rm `make print-objdir`; make cleandir; make obj
618	(If you built the tree without "make obj" in the past, obsolete files
619	may remain.  The command tries to clean everything up)
620
621Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible
622	pointer type
623Fix:	Rebuild and install usr.bin/menuc
624
625Symptom:mklocale not found during build in share/locale/ctype
626Fix:	Build and install usr.bin/mklocale
627
628Symptom:undefined reference to `__assert13' or `__unsetenv13'
629Fix:    Rebuild and install lib/libc
630
631Symptom:usr.bin/config fails to build.
632Fix:	Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
633
634Symptom:undefined reference to `getprogname' or `setprogname'
635Fix:    Rebuild and install lib/libc
636
637Symptom:Update build fails in src/tools/gcc complaining that a variable
638	(e.g. CPPFLAGS) has changed since the previous run.
639Fix:    Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
640
641Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
642	No such file or directory.
643Cause:	If a directory is created by mistake, then it is sometimes
644	deleted from the CVS repository using administrative commands
645	that bypass the normal cvs access controls.  If your cvs working tree
646	contains references to a directory that has been deleted on the
647	server in this way, then "cvs update" reports this error.
648Fix:	Recursively delete the affected directory from your working tree
649	and try the update again.
