1.1 abs 2:
1.123 jmc 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.
1.1 abs 6:
1.123 jmc 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.

16: Recent changes:
17: ^^^^^^^^^^^^^^^
1.130 christos 18: 20041201:
19: Userland programs have been changed to use /dev/bpf instead of
20: /dev/bpfX. You need to create that device by installing a new
1.131 wiz 21: MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]*
1.99 mrg 22:
1.129 jmc 23: 20041006:
24:
25: A bug was introduced into /bin/sh (var.c rev 1.35) which causes
26: variables to not export correctly to subshells in all cases. This
27: will cause builds to break if that version of /bin/sh is installed
28: on the system. The proper version of /bin/sh can be verified with:
29:
30: ident /bin/sh | grep var
31:
32: Any /bin/sh w. version 1.35 will not work and needs to be updated
33: before attempting a build.
34:
1.127 christos 35: 20041001:
36: The ipfilter kernel sources moved from sys/netinet to
37: dist/sys/ipf/netinet. Due to the move some Makefile
38: dependencies are now dangling requiring a make cleandir
1.128 he 39: before they work again (kdump, ktruss, rescue, ipf, and
40: ftp-proxy are the victims).
1.127 christos 41:
1.125 atatat 42: 20040715:
43: The rc.d/sendmail script now uses a heuristic to determine
44: if sendmail should be started at boot time. It checks the
45: contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
46: owner and mode of the sendmail binary to see if any changes
47: to the mail infrastructure have been made. If no changes
48: are detected, it will start an SMTP listener.
49:
50: Setting sendmail=NO in /etc/rc.conf will override this.
51:
52: If you are only using sendmail by default and only for
53: local delivery, it is important that you also update your
54: sendmail.cf so that the SMTP listener only listens on the
55: loopback interface.
56:
57: 20040715:
58: The method by which athhal-elf.o gets pulled into i386
59: kernel builds has been changed again. The latest version
60: of bsd.files.mk is no longer required.
61:
1.124 jmc 62: 20040621:
63: Due to the recent rototill of tools/compat it's crucial one starts
64: from a clean objdir under tools/*.
65:
66: This is mostly due to generated files (yacc and lex sources) needing
1.125 atatat 67: to be generated with new rules from bsd.hostprog.mk.
1.124 jmc 68:
69: The safest course is to rm -rf all objects under tools before building.
70:
1.121 lukem 71: 20040516:
72: The end-user modifiable X11 configuration has been moved
73: from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
74: Ensure that src and xsrc is up to date, and run
75: "make cleandir" in src/x11 before your next build.
76:
1.126 lukem 77: postinstall currently doesn't migrate the files from
78: /usr/X11R6/lib/X11/* to /etc/X11/* although it does
79: detect that this needs to occur, so you'll have to
80: manually move these files yourself.
81:
1.119 atatat 82: 20040426:
83: Support for the original dynamic sysctl node structure has
84: been removed in favor of the newer layout. This affects
85: consumers of the create and delete interface, as well as
86: the dynamic discovery mechanism. This is believed only to
87: be the sysctl(8) binary itself, at this point in time, so
88: the only effect of this should be that a sysctl binary
89: built from sources dated between 2003/12/04 and 2004/03/24
90: will not work on a kernel built from sources dated after
91: 2004/04/25. If you need a new sysctl binary but build.sh
92: does not work, make sure that your revision of
1.120 atatat 93: src/sys/sys/sysctl.h is 1.112 (or later), and then the
94: do the following:
1.119 atatat 95:
1.120 atatat 96: cd /usr/src (or wherever your source tree is)
97: make USETOOLS=no includes
98: cd lib/libc
99: make USETOOLS=no dependall install
100: cd ../../sbin/sysctl
1.119 atatat 101: make USETOOLS=no dependall install
102:
1.122 itojun 103: If you are using older sysctl binary, GNU autoconf would fail to
104: identify your machine architecture, and tries to build binary for
105: "unknown-unknown-netbsd20F" or something like that. if that happens,
106: make sure to follow the above steps.
107:
1.118 dbj 108: 20040425:
109: The ffs superblock issues listed below under 20040109 and 20030402
110: are now automatically addressed by the /etc/rc.d/fixsb script or by
111: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
112: invocation mentioned below will continue to work and is now
113: automated by those scripts. Note that under certain circumstances,
114: affected filesystems upgraded to a -current kernel first before
115: upgrading their userland with the fixsb and fsck_ffs fixes may
116: encounter a 'freeing free inode' panic when writing to the affected
117: filesystem, so it is a good idea to repair the filesystem as soon as
118: possible. For more details on the fixsb script, see pr install/25138.
119:
1.115 christos 120: 20040418:
1.121 lukem 121: statfs(2) and friends have been replaced with statvfs(2). Before
1.115 christos 122: installing a newly build userland make sure that you are running
123: a newly built kernel with COMPAT_20 set. In addition your libc
124: build might not work (undefined SYS_statfs symbol) because make
125: clean does not know how to remove files it does not know about
1.116 christos 126: anymore. Manually remove all generated .S sources and objects
127: from the libc build directory.
1.115 christos 128:
1.114 jmc 129: 20040326:
130: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 131: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 132: and the generated Makefile will use the new .uue rules from bsd.file.mk
133: to build it.
134:
135: This means you must have the latest bsd.files.mk installed when
136: building a kernel without USETOOLS=yes.
137:
1.113 dan 138: 20040318:
139: A bug in the cgd(4) blowfish code was corrected, without
140: provision of backwards compatibility, after several public
141: notices over several months. Users of cgd with blowfish cipher
142: ONLY must dump their data before updating their kernels, and
143: recreate cgd's and restore data using the new kernel. See
144: (recent message to current-users, URL when mail-index has updated)
145:
1.108 bjh21 146: 20040313:
147: On acorn32, the opms and qms drivers have been withdrawn, and
148: the old wsqms driver is now called qms. Kernel config files
149: will need updating. See the ones in sys/arch/acorn32/conf
150: for examples.
151:
1.106 bjh21 152: 20040125:
153: On acorn32, the beep and sysbeep devices are no longer
154: needed, and will need to be deleted from kernel configuration
155: files.
1.105 bjh21 156:
1.102 dbj 157: 20040109:
158: Compatibility for old ffs superblock layouts has been
159: added, and the restrictive fsck checks have been reenabled
160: when using those layouts. If you have been using -current
161: since 20030402, you may find that fsck again signals fatal
1.110 dbj 162: superblock mismatches. To repair, make sure you have
1.111 simonb 163: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 164: to complete the filesystem upgrade. A message has
1.111 simonb 165: been added to the kernel which should detect this problem.
166: See the following discussion for more information:
1.112 keihan 167: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 168:
1.99 mrg 169: 20031203:
1.100 keihan 170: New binutils builds may fail due to old dependencies.
1.99 mrg 171: It's necessary to "make cleandir" to ensure that
172: the dependencies will be rebuilt correctly.
1.98 wiz 173:
174: 20031111:
175: A newer mkdep is needed. Error noting that is
176: cc: Ambiguous abbreviation --
1.97 lukem 177:
178: 20031008:
179: /usr/include/sys/disklabel_mbr.h was removed.
180: It's necessary to "make cleandir" to ensure that
181: the dependencies will be rebuilt correctly.
1.96 christos 182:
1.109 dbj 183: 20031007:
1.111 simonb 184: A sign exension bug was fixed which set all the high bits
185: of our newly expanded ffs fs_flags. This should only
186: affect users who installed or upgraded in September of 2003.
1.109 dbj 187: A small utility program was posted to tech-kern which
1.111 simonb 188: should fix this problem, and a warning message was added
189: to the kernel which should discover and warn about it. See
190: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 191:
1.96 christos 192: 20030906:
193: With the addition of siginfo support the old signal trampoline
194: code has been deprecated to COMPAT_16. Make sure that your running
195: kernel has COMPAT_16 enabled before building userland.
1.94 christos 196:
197: 20030801:
1.95 wiz 198: With the new openssl, there is some header and library shuffling.
1.94 christos 199: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 200: /usr/lib/libdes* before building.
1.92 wiz 201:
202: 20030703:
203: Texinfo was updated to 4.6. To avoid failures when trying to
204: build the included texinfo files, do:
205:
206: cd src/gnu/usr.bin/texinfo
207: make MKINFO=no dependall install
1.90 wiz 208:
209: 20030630:
1.101 junyoung 210: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 211: cd share/mk && make install
1.90 wiz 212: cd src/gnu/usr.bin/groff
213: make MKMAN=no dependall install
214: (untested).
1.89 christos 215:
216: 20030516:
217: Due to bugs in the export handling code, invalid export lines
218: were accepted before and caused the kernel to panic when
219: mountd got restarted because it freed memory that had already
220: been freed. This has been fixed and the kernel checks
221: export addresses very strictly. If you upgrade your kernel,
222: make sure you also upgrade mountd, because if your export
223: file contains lines with an old inet4 address syntax (i.e.
224: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 225:
226: 20030402:
227: The superblock layout for FFS was changed. If you have 1.6
228: fsck binaries, they will signal a fatal superblock mismatch
229: with the first alternate, because they compare too many
230: fields (even ones that aren't useful). If possible, upgrade
231: your fsck_ffs binary before using a new kernel.
232: None of this signals actual filesystem damage.
1.85 atatat 233:
234: 20030324:
235: sendmail version 8.12.8 was imported. Since sendmail is
236: now setgid to the smmsp group, and runs in "collection"
237: mode for most common activities, there is a new config
238: file called submit.cf that needs to live in /etc/mail.
239: The generic submit.cf sample in /usr/share/sendmail/cf
240: is named netbsd-msp.cf. Upgrading your regular sendmail
241: configuration file is also strongly advised.
242:
243: See the section named "MESSAGE SUBMISSION PROGRAM" in
244: the updated /usr/share/sendmail/README file for more
245: information.
1.82 wiz 246:
247: 20030117:
248: Texinfo was updated to 4.3. To avoid failures when trying to
249: build the included texinfo files, do:
250:
251: cd src/gnu/usr.bin/texinfo
252: make MKINFO=no dependall install
1.81 lukem 253:
254: 20021223:
255: The METALOG format changed slightly, to remove the leading
256: "${DESTDIR}" from path names.
257: This only affects people building with UNPRIVED.
258: For complete safety, remove the DESTDIR entirely and
259: update tools/mtree, before running make build.
1.88 itojun 260:
261: 20021219:
262: CVS repository layout was changed. See the following for details
263: if you are using (anonymous) cvs to update your tree.
264:
1.93 salo 265: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 266:
267: 20021219:
268: install(1) had a '-N dbdir' option added, to specify an
269: alternate location to look up users & groups (instead
270: of the host system passwd(5) and group(5) databases).
271:
272: The build system was modified to take advantage of
273: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 274: use USETOOLS==no, you may have to rebuild and
1.80 lukem 275: reinstall usr.bin/xinstall first.
1.78 lukem 276:
277: 20021130:
278: fparseln(3) moved from libutil to libc.
279: If building to DESTDIR=/, reinstall the includes
280: and rebuild libc:
281: make includes
282: make do-lib-libc
283: If using build.sh, "cd tools/compat && make clean"
284: before rebuilding the tools.
1.77 lukem 285:
286: 20021126:
287: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
288: including the optional "SYS_INCLUDE=symlinks" support.
289: All header files, including <sys/*.h> are copied into
290: /usr/include.
1.76 thorpej 291:
292: 20021121:
293: The C run-time support files crtbegin.o and crtend.o
294: (and their companions crtbeginS.o and crtendS.o) were
295: split up, with new crti.o and crtn.o files resulting.
296: This means that libtool needs to be rebuilt once the
297: new libraries are installed. The process of rebuilding
298: libtool will cause it to automatically notice the new
299: required files, but it *must* be rebuilt in order to
300: do this.
301:
302: An out-of-date libtool will result in shared libraries
303: which lack _init() and _fini() routines, which means that
304: their global contructors/destructors will not be invoked.
1.75 thorpej 305:
306: 20021121:
307: A bug related to how ARM ELF objects were tagged has been
308: corrected.
309:
310: NetBSD ARM ELF uses the soft-VFP floating point model by
311: default. However, the assembler lacked support for marking
312: objects as using the VFP floating point format, and the
1.79 wiz 313: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 314: to the assembler.
315:
316: Unfortunately, this means that the linker will now consider
317: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
318: incompatible with new (properly marked) objects.
319:
320: The problem will only manifest itself if you attempt to compile
321: a new program using the fixed toolchain, and link that program
322: against old libraries which do not have the proper "softvfp"
323: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
324: WILL CONTINUE TO WORK PROPERLY.
325:
326: The only work-around for the problem is to recompile all of
327: the libraries on the system. The easiest way to do this for
1.79 wiz 328: system libraries is to install a binary snapshot; they are
1.93 salo 329: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 330: have installed which supply libraries will have to be recompiled
331: if you wish to link new programs against those libraries.
332:
333: If you have questions about this matter, please contact
1.93 salo 334: port-arm@NetBSD.org.
1.73 provos 335:
336: 20021011:
337: Systrace has been improved to support privilege elevation.
338: Updating the kernel requires the userland part of systrace
1.79 wiz 339: to be rebuilt.
1.72 thorpej 340:
341: 20021010:
342: The config(8) grammar was changed to allow options to register
343: dependencies on attributes, as well as other options. Users
344: must update and reinstall usr.sbin/config before building a new
345: kernel.
1.70 thorpej 346:
347: 20021009:
348: A new attribute dependency syntax was introduced to config(8),
349: which is now used by the SCSI configuration description. Users
1.71 wiz 350: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 351: kernel.
1.69 thorpej 352:
353: 20021003:
354: Several changes have been made to the autoconfiguration
355: framework. Users must update and reinstall usr.sbin/config
356: before building a new kernel.
1.74 jschauma 357:
358: 20021001:
359: The i386mp branch has been merged. To compile a kernel, users
360: will need to add the option 'cpu* at mainbus?' to their configuration
361: file. Multiprocessor kernels will need
362: ioapic* at mainbus? apid ?
363: options MULTIPROCESSOR
364: options COM_MPLOCK
1.68 lukem 365:
366: 20020922:
367: MKDYNAMICROOT=yes enabled by default, which means that
368: certain shared libraries are installed into /lib, the shared
369: linker is installed into /libexec, and all programs in /bin
370: and /sbin are dynamically linked.
371: If you do not use "make build", you should ensure that
372: you have the libraries and shared linker in the new locations,
373: with:
374: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 375:
376: 20020917:
377: USE_NEW_TOOLCHAIN has been replaced with:
378: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
379: there is no working in-tree toolchain (hppa, ns32k, sh5,
380: x86_64).
381: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 382: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 383: enables the cross-build framework even for TOOLCHAIN_MISSING
384: platforms.
1.66 gehenna 385:
386: 20020906:
387: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 388: reinstall usr.sbin/config before building the kernel.
1.65 lukem 389:
390: 20020822:
391: Crunched rescue tools (contents of /bin and /sbin, plus others)
392: are now provided in /rescue.
393:
394: To ensure that these are built statically linked (no matter
395: what the setting of LDSTATIC is), use a crunchgen(1) built
396: from sources newer than 20020820 (see the next entry).
397:
398: 20020820:
399: crunchgen(1) changed to ensure that the generated program
400: is statically linked.
401:
402: Solution: update and reinstall usr.bin/crunch

431: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 432:
433: 20020426:
434: etc/postinstall added, which performs various checks for
435: configuration file updates and changes, and can fix most of
436: the problems identified.
437: This should make it much easier to upgrade a system's
438: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 439:
440: 20020320:

472: If you're attempting to build a snapshot on sparc64 and are getting
473: reloc errors from the toolchain groff binary this means your native
474: toolchain has some broken C++ bits.
475:
476: To fix:
477:
478: Build a new toolchain (i.e. build.sh -t)
479: Use the new toolchain to build and install natively (i.e. /usr/lib)
480:

514: manual update log.
515:
516: Users building a USE_NEW_TOOLCHAIN system should read the

1.30 enami 554:
1.64 sommerfe 555: 20010803:
1.41 wiz 556: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 557: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 558: kernel successfully, you need to build and install a new toolchain,
559: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
560: from your kernel configuration until you rebuild your userland.
561: See 20011029 above and BUILDING file in this directory for more information.
562: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]

577: Enabled correct .init/.fini processing in crt0. The way this
578: was done was to change a -I directive to cc(1), which means
579: make(1) will have a stale dependency (it will be checking the
580: timestamp on the wrong "dot_init.h").
581:
582: The symptom you will see is that new programs die with SIGSEGV
583: if you have a stale dependency.
584:
585: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
586: before starting your build.
1.26 thorpej 587:
588: 20010628:

622: needs to be installed before make build.
1.10 christos 623:
624: 20010114:
625: introduce .if commands(target) in make(1). You need to
626: bring everything up-to-date first, then without installing
1.23 tron 627: anything make and install in usr.bin/make, then proceed
1.10 christos 628: with make build.

1.8 sommerfe 633:
634: 20001230:
635: New share/mk files needed to support .WAIT in SUBDIR variables.
636: If you get make errors,

638: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 639:

1.7 ad 641: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 642: major and minor numbers haven't changed, you should update your /dev
643: directory.
1.1 abs 644:

646: The following make directives are obsoleted.
647: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
648: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 649: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 650: additional library libcrypto_{idea,rc5}.
1.1 abs 651:
652:
653: Hints for a more successful build:
654: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 655: Use build.sh, but do not use its "expert mode":
1.132 ! jmmv 656: This will automatically build the tools in the
1.123 jmc 657: correct order, and it will keep the tools and the
658: new build products from interfering with the running
659: system. This will allow you to ignore most of the
660: other advice in this file.
1.2 mrg 661: Build a new kernel first:
662: This makes sure that any new system calls or features
663: expected by the new userland will be present. This
664: helps to avoid critical errors when upgrading.
1.1 abs 665: Use object directories:
666: This helps to keep stale object
667: files from polluting the build if a Makefile "forgets"
668: about one. It also makes it easier to clean up after
669: a build. It's also necessary if you want to use the
670: same source tree for multiple machines.
1.123 jmc 671: To use object directories with build.sh:
672: a) invoke build.sh with the "-M" or "-O" options.
673: To use object directories without using build.sh:
1.1 abs 674: a) cd /usr/src ; make cleandir
1.2 mrg 675: b) Add "OBJMACHINE=yes" to /etc/mk.conf
676: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 677: d) cd /usr/src ; make build
1.2 mrg 678: Note that running "make obj" in a directory will create
679: in obj.$MACHINE directory.
1.1 abs 680: Build to a DESTDIR:
1.123 jmc 681: This helps to keep old installed files (especially libraries)
682: from interfering with the new build.
683: To build to a DESTDIR with build.sh, use the "-D" option.
684: To build to a DESTDIR without using build.sh, set the DESTDIR
685: environment variable before running make build. It should be
686: set to the pathname of an initially empty directory.
687: Problems: if you do not use build.sh, you might need to
688: update critical utilities without using DESTDIR since
689: nothing is executed from what is installed in DESTDIR.
690: (See critical utils, below.)
1.1 abs 691: Build often:
692: This keeps critical utilities current enough to not choke
693: on any other part of the source tree that depends on up to
1.123 jmc 694: date functionality. If you use build.sh, you should not have
695: this problem.
1.1 abs 696:
697: What to do if things don't work:
698: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
699: When things don't work there is usually a few things that commonly
700: should be done.
701: 1) make includes
702: This should be done automatically by make build.
703: 2) cd share/mk && make install
704: Again, automatically done by make build.
705:
706: Failsafe rebuild of a small part of the tree:
707: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
708: To make sure you rebuild something correctly you want to do
709: something like the following:
710: 1) Make sure the includes and .mk files are up to date.
711: 2) Make sure any program used to build the particular
712: utility is up to date. (yacc, lex, etc...)
713: 3) cd ...path/to/util...
714: make cleandir
715: rm ...all obj directories...
716: make cleandir # yes, again
717: make obj
718: make depend && make
719:
720: Failsafe rebuild of the entire tree:
721: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
722: If you really want to make sure the source tree is clean and
1.2 mrg 723: ready for a build try the following. Note that sourcing /etc/mk.conf
724: (a make(1) Makefile) in this manner is not right, and will not work
725: for anyone who uses any make(1) features in /etc/mk.conf.
