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.

17: ^^^^^^^^^^^^^^^
1.99 mrg 18:
1.125 ! atatat 19: 20040715:
! 20: The rc.d/sendmail script now uses a heuristic to determine
! 21: if sendmail should be started at boot time. It checks the
! 22: contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
! 23: owner and mode of the sendmail binary to see if any changes
! 24: to the mail infrastructure have been made. If no changes
! 25: are detected, it will start an SMTP listener.
! 26:
! 27: Setting sendmail=NO in /etc/rc.conf will override this.
! 28:
! 29: If you are only using sendmail by default and only for
! 30: local delivery, it is important that you also update your
! 31: sendmail.cf so that the SMTP listener only listens on the
! 32: loopback interface.
! 33:
! 34: 20040715:
! 35: The method by which athhal-elf.o gets pulled into i386
! 36: kernel builds has been changed again. The latest version
! 37: of bsd.files.mk is no longer required.
! 38:
1.124 jmc 39: 20040621:
40: Due to the recent rototill of tools/compat it's crucial one starts
41: from a clean objdir under tools/*.
42:
43: This is mostly due to generated files (yacc and lex sources) needing
1.125 ! atatat 44: to be generated with new rules from bsd.hostprog.mk.
1.124 jmc 45:
46: The safest course is to rm -rf all objects under tools before building.
47:
1.121 lukem 48: 20040516:
49: The end-user modifiable X11 configuration has been moved
50: from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
51: Ensure that src and xsrc is up to date, and run
52: "make cleandir" in src/x11 before your next build.
53:
1.119 atatat 54: 20040426:
55: Support for the original dynamic sysctl node structure has
56: been removed in favor of the newer layout. This affects
57: consumers of the create and delete interface, as well as
58: the dynamic discovery mechanism. This is believed only to
59: be the sysctl(8) binary itself, at this point in time, so
60: the only effect of this should be that a sysctl binary
61: built from sources dated between 2003/12/04 and 2004/03/24
62: will not work on a kernel built from sources dated after
63: 2004/04/25. If you need a new sysctl binary but build.sh
64: does not work, make sure that your revision of
1.120 atatat 65: src/sys/sys/sysctl.h is 1.112 (or later), and then the
66: do the following:
1.119 atatat 67:
1.120 atatat 68: cd /usr/src (or wherever your source tree is)
69: make USETOOLS=no includes
70: cd lib/libc
71: make USETOOLS=no dependall install
72: cd ../../sbin/sysctl
1.119 atatat 73: make USETOOLS=no dependall install
74:
1.122 itojun 75: If you are using older sysctl binary, GNU autoconf would fail to
76: identify your machine architecture, and tries to build binary for
77: "unknown-unknown-netbsd20F" or something like that. if that happens,
78: make sure to follow the above steps.
79:
1.118 dbj 80: 20040425:
81: The ffs superblock issues listed below under 20040109 and 20030402
82: are now automatically addressed by the /etc/rc.d/fixsb script or by
83: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
84: invocation mentioned below will continue to work and is now
85: automated by those scripts. Note that under certain circumstances,
86: affected filesystems upgraded to a -current kernel first before
87: upgrading their userland with the fixsb and fsck_ffs fixes may
88: encounter a 'freeing free inode' panic when writing to the affected
89: filesystem, so it is a good idea to repair the filesystem as soon as
90: possible. For more details on the fixsb script, see pr install/25138.
91:
1.115 christos 92: 20040418:
1.121 lukem 93: statfs(2) and friends have been replaced with statvfs(2). Before
1.115 christos 94: installing a newly build userland make sure that you are running
95: a newly built kernel with COMPAT_20 set. In addition your libc
96: build might not work (undefined SYS_statfs symbol) because make
97: clean does not know how to remove files it does not know about
1.116 christos 98: anymore. Manually remove all generated .S sources and objects
99: from the libc build directory.
1.115 christos 100:
1.114 jmc 101: 20040326:
102: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 103: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 104: and the generated Makefile will use the new .uue rules from bsd.file.mk
105: to build it.
106:
107: This means you must have the latest bsd.files.mk installed when
108: building a kernel without USETOOLS=yes.
109:
1.113 dan 110: 20040318:
111: A bug in the cgd(4) blowfish code was corrected, without
112: provision of backwards compatibility, after several public
113: notices over several months. Users of cgd with blowfish cipher
114: ONLY must dump their data before updating their kernels, and
115: recreate cgd's and restore data using the new kernel. See
116: (recent message to current-users, URL when mail-index has updated)
117:
1.108 bjh21 118: 20040313:
119: On acorn32, the opms and qms drivers have been withdrawn, and
120: the old wsqms driver is now called qms. Kernel config files
121: will need updating. See the ones in sys/arch/acorn32/conf
122: for examples.
123:
1.106 bjh21 124: 20040125:
125: On acorn32, the beep and sysbeep devices are no longer
126: needed, and will need to be deleted from kernel configuration
127: files.
1.105 bjh21 128:
1.102 dbj 129: 20040109:
130: Compatibility for old ffs superblock layouts has been
131: added, and the restrictive fsck checks have been reenabled
132: when using those layouts. If you have been using -current
133: since 20030402, you may find that fsck again signals fatal
1.110 dbj 134: superblock mismatches. To repair, make sure you have
1.111 simonb 135: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 136: to complete the filesystem upgrade. A message has
1.111 simonb 137: been added to the kernel which should detect this problem.
138: See the following discussion for more information:
1.112 keihan 139: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 140:
1.99 mrg 141: 20031203:
1.100 keihan 142: New binutils builds may fail due to old dependencies.
1.99 mrg 143: It's necessary to "make cleandir" to ensure that
144: the dependencies will be rebuilt correctly.
1.98 wiz 145:
146: 20031111:
147: A newer mkdep is needed. Error noting that is
148: cc: Ambiguous abbreviation --
1.97 lukem 149:
150: 20031008:
151: /usr/include/sys/disklabel_mbr.h was removed.
152: It's necessary to "make cleandir" to ensure that
153: the dependencies will be rebuilt correctly.
1.96 christos 154:
1.109 dbj 155: 20031007:
1.111 simonb 156: A sign exension bug was fixed which set all the high bits
157: of our newly expanded ffs fs_flags. This should only
158: affect users who installed or upgraded in September of 2003.
1.109 dbj 159: A small utility program was posted to tech-kern which
1.111 simonb 160: should fix this problem, and a warning message was added
161: to the kernel which should discover and warn about it. See
162: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 163:
1.96 christos 164: 20030906:
165: With the addition of siginfo support the old signal trampoline
166: code has been deprecated to COMPAT_16. Make sure that your running
167: kernel has COMPAT_16 enabled before building userland.
1.94 christos 168:
169: 20030801:
1.95 wiz 170: With the new openssl, there is some header and library shuffling.
1.94 christos 171: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 172: /usr/lib/libdes* before building.
1.92 wiz 173:
174: 20030703:
175: Texinfo was updated to 4.6. To avoid failures when trying to
176: build the included texinfo files, do:
177:
178: cd src/gnu/usr.bin/texinfo
179: make MKINFO=no dependall install
1.90 wiz 180:
181: 20030630:
1.101 junyoung 182: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 183: cd share/mk && make install
1.90 wiz 184: cd src/gnu/usr.bin/groff
185: make MKMAN=no dependall install
186: (untested).
1.89 christos 187:
188: 20030516:
189: Due to bugs in the export handling code, invalid export lines
190: were accepted before and caused the kernel to panic when
191: mountd got restarted because it freed memory that had already
192: been freed. This has been fixed and the kernel checks
193: export addresses very strictly. If you upgrade your kernel,
194: make sure you also upgrade mountd, because if your export
195: file contains lines with an old inet4 address syntax (i.e.
196: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 197:
198: 20030402:
199: The superblock layout for FFS was changed. If you have 1.6
200: fsck binaries, they will signal a fatal superblock mismatch
201: with the first alternate, because they compare too many
202: fields (even ones that aren't useful). If possible, upgrade
203: your fsck_ffs binary before using a new kernel.
204: None of this signals actual filesystem damage.
1.85 atatat 205:
206: 20030324:
207: sendmail version 8.12.8 was imported. Since sendmail is
208: now setgid to the smmsp group, and runs in "collection"
209: mode for most common activities, there is a new config
210: file called submit.cf that needs to live in /etc/mail.
211: The generic submit.cf sample in /usr/share/sendmail/cf
212: is named netbsd-msp.cf. Upgrading your regular sendmail
213: configuration file is also strongly advised.
214:
215: See the section named "MESSAGE SUBMISSION PROGRAM" in
216: the updated /usr/share/sendmail/README file for more
217: information.
1.82 wiz 218:
219: 20030117:
220: Texinfo was updated to 4.3. To avoid failures when trying to
221: build the included texinfo files, do:
222:
223: cd src/gnu/usr.bin/texinfo
224: make MKINFO=no dependall install
1.81 lukem 225:
226: 20021223:
227: The METALOG format changed slightly, to remove the leading
228: "${DESTDIR}" from path names.
229: This only affects people building with UNPRIVED.
230: For complete safety, remove the DESTDIR entirely and
231: update tools/mtree, before running make build.
1.88 itojun 232:
233: 20021219:
234: CVS repository layout was changed. See the following for details
235: if you are using (anonymous) cvs to update your tree.
236:
1.93 salo 237: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 238:
239: 20021219:
240: install(1) had a '-N dbdir' option added, to specify an
241: alternate location to look up users & groups (instead
242: of the host system passwd(5) and group(5) databases).
243:
244: The build system was modified to take advantage of
245: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 246: use USETOOLS==no, you may have to rebuild and
1.80 lukem 247: reinstall usr.bin/xinstall first.
1.78 lukem 248:
249: 20021130:
250: fparseln(3) moved from libutil to libc.
251: If building to DESTDIR=/, reinstall the includes
252: and rebuild libc:
253: make includes
254: make do-lib-libc
255: If using build.sh, "cd tools/compat && make clean"
256: before rebuilding the tools.
1.77 lukem 257:
258: 20021126:
259: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
260: including the optional "SYS_INCLUDE=symlinks" support.
261: All header files, including <sys/*.h> are copied into
262: /usr/include.
1.76 thorpej 263:
264: 20021121:
265: The C run-time support files crtbegin.o and crtend.o
266: (and their companions crtbeginS.o and crtendS.o) were
267: split up, with new crti.o and crtn.o files resulting.
268: This means that libtool needs to be rebuilt once the
269: new libraries are installed. The process of rebuilding
270: libtool will cause it to automatically notice the new
271: required files, but it *must* be rebuilt in order to
272: do this.
273:
274: An out-of-date libtool will result in shared libraries
275: which lack _init() and _fini() routines, which means that
276: their global contructors/destructors will not be invoked.
1.75 thorpej 277:
278: 20021121:
279: A bug related to how ARM ELF objects were tagged has been
280: corrected.
281:
282: NetBSD ARM ELF uses the soft-VFP floating point model by
283: default. However, the assembler lacked support for marking
284: objects as using the VFP floating point format, and the
1.79 wiz 285: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 286: to the assembler.
287:
288: Unfortunately, this means that the linker will now consider
289: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
290: incompatible with new (properly marked) objects.
291:
292: The problem will only manifest itself if you attempt to compile
293: a new program using the fixed toolchain, and link that program
294: against old libraries which do not have the proper "softvfp"
295: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
296: WILL CONTINUE TO WORK PROPERLY.
297:
298: The only work-around for the problem is to recompile all of
299: the libraries on the system. The easiest way to do this for
1.79 wiz 300: system libraries is to install a binary snapshot; they are
1.93 salo 301: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 302: have installed which supply libraries will have to be recompiled
303: if you wish to link new programs against those libraries.
304:
305: If you have questions about this matter, please contact
1.93 salo 306: port-arm@NetBSD.org.
1.73 provos 307:
308: 20021011:
309: Systrace has been improved to support privilege elevation.
310: Updating the kernel requires the userland part of systrace
1.79 wiz 311: to be rebuilt.
1.72 thorpej 312:
313: 20021010:
314: The config(8) grammar was changed to allow options to register
315: dependencies on attributes, as well as other options. Users
316: must update and reinstall usr.sbin/config before building a new
317: kernel.
1.70 thorpej 318:
319: 20021009:
320: A new attribute dependency syntax was introduced to config(8),
321: which is now used by the SCSI configuration description. Users
1.71 wiz 322: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 323: kernel.
1.69 thorpej 324:
325: 20021003:
326: Several changes have been made to the autoconfiguration
327: framework. Users must update and reinstall usr.sbin/config
328: before building a new kernel.
1.74 jschauma 329:
330: 20021001:
331: The i386mp branch has been merged. To compile a kernel, users
332: will need to add the option 'cpu* at mainbus?' to their configuration
333: file. Multiprocessor kernels will need
334: ioapic* at mainbus? apid ?
335: options MULTIPROCESSOR
336: options COM_MPLOCK
1.68 lukem 337:
338: 20020922:
339: MKDYNAMICROOT=yes enabled by default, which means that
340: certain shared libraries are installed into /lib, the shared
341: linker is installed into /libexec, and all programs in /bin
342: and /sbin are dynamically linked.
343: If you do not use "make build", you should ensure that
344: you have the libraries and shared linker in the new locations,
345: with:
346: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 347:
348: 20020917:
349: USE_NEW_TOOLCHAIN has been replaced with:
350: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
351: there is no working in-tree toolchain (hppa, ns32k, sh5,
352: x86_64).
353: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 354: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 355: enables the cross-build framework even for TOOLCHAIN_MISSING
356: platforms.
1.66 gehenna 357:
358: 20020906:
359: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 360: reinstall usr.sbin/config before building the kernel.
1.65 lukem 361:
362: 20020822:
363: Crunched rescue tools (contents of /bin and /sbin, plus others)
364: are now provided in /rescue.
365:
366: To ensure that these are built statically linked (no matter
367: what the setting of LDSTATIC is), use a crunchgen(1) built
368: from sources newer than 20020820 (see the next entry).
369:
370: 20020820:
371: crunchgen(1) changed to ensure that the generated program
372: is statically linked.
373:
374: Solution: update and reinstall usr.bin/crunch
1.84 grant 375:
376: 20020605:

400: the build process).
1.60 sommerfe 401:
402: 20020426:
403: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 404:
405: 20020426:
406: etc/postinstall added, which performs various checks for
407: configuration file updates and changes, and can fix most of
408: the problems identified.
409: This should make it much easier to upgrade a system's
410: configuration from earlier systems (as far back as NetBSD 1.5).

1.56 lukem 415:
1.55 itojun 416: 20020319:
1.79 wiz 417: Raw IPv6 socket now makes strict checking for sa_family and sa_len
418: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 419: newer than November 2001 when you upgrade the kernel.
420:
1.54 itojun 421: 20020311:
422: ssh configuration files were moved from /etc to /etc/ssh. Beware
423: if you restart your machine from remote. Note that sshd.conf needs
424: to be changed (due to the use of "/etc" inside).
425:
426: 20020223:
1.53 matt 427: Users of the VAX port will need to rebuild and install gas
428: so it deal with the now present register prefix used in all
429: the VAX assembly files.
430:
1.50 itojun 431: 20020118:
432: ntpd user/group has been added. Need to hand add this in or builds

444: If you're attempting to build a snapshot on sparc64 and are getting
445: reloc errors from the toolchain groff binary this means your native
446: toolchain has some broken C++ bits.
447:
448: To fix:
449:
450: Build a new toolchain (i.e. build.sh -t)
451: Use the new toolchain to build and install natively (i.e. /usr/lib)
452:
453: gnu/lib/libgcc

460: you've built and installed a system with the new toolchain up to this
1.52 wiz 461: point you do not have a working awk as its ability to do floating
1.47 jmc 462: point is broken.
463:
464: To build:
465:
466: remake and install gnu/lib/libgcc

482: The new document BUILDING.mdoc (view with nroff | more, or
483: see pre-generated .txt and .html versions) describes the build
484: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
485: build process, are intended in the long run to replace this
486: manual update log.
487:
488: Users building a USE_NEW_TOOLCHAIN system should read the
489: BUILDING document for caveats. Generally, BUILDING supersedes
490: UPDATING for these systems, as tool updating is taken care of
491: by the new build system.

1.64 sommerfe 527: 20010803:
1.41 wiz 528: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 529: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 530: kernel successfully, you need to build and install a new toolchain,
531: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
532: from your kernel configuration until you rebuild your userland.
533: See 20011029 above and BUILDING file in this directory for more information.

549: Enabled correct .init/.fini processing in crt0. The way this
550: was done was to change a -I directive to cc(1), which means
551: make(1) will have a stale dependency (it will be checking the
552: timestamp on the wrong "dot_init.h").
553:
554: The symptom you will see is that new programs die with SIGSEGV
555: if you have a stale dependency.
556:
557: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
558: before starting your build.
1.26 thorpej 559:

1.4 itojun 622: additional library libcrypto_{idea,rc5}.
1.1 abs 623:
624:
625: Hints for a more successful build:
626: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 627: Use build.sh, but do not use its "expert mode":
628: This will will automatically build the tools in the
629: correct order, and it will keep the tools and the
630: new build products from interfering with the running
631: system. This will allow you to ignore most of the
632: other advice in this file.
1.2 mrg 633: Build a new kernel first:
634: This makes sure that any new system calls or features
635: expected by the new userland will be present. This
636: helps to avoid critical errors when upgrading.
1.1 abs 637: Use object directories:
638: This helps to keep stale object
639: files from polluting the build if a Makefile "forgets"
640: about one. It also makes it easier to clean up after
641: a build. It's also necessary if you want to use the
642: same source tree for multiple machines.
1.123 jmc 643: To use object directories with build.sh:
644: a) invoke build.sh with the "-M" or "-O" options.
645: To use object directories without using build.sh:
1.1 abs 646: a) cd /usr/src ; make cleandir
1.2 mrg 647: b) Add "OBJMACHINE=yes" to /etc/mk.conf
648: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 649: d) cd /usr/src ; make build
1.2 mrg 650: Note that running "make obj" in a directory will create
651: in obj.$MACHINE directory.
1.1 abs 652: Build to a DESTDIR:
1.123 jmc 653: This helps to keep old installed files (especially libraries)
654: from interfering with the new build.
655: To build to a DESTDIR with build.sh, use the "-D" option.
656: To build to a DESTDIR without using build.sh, set the DESTDIR
657: environment variable before running make build. It should be
658: set to the pathname of an initially empty directory.
659: Problems: if you do not use build.sh, you might need to
660: update critical utilities without using DESTDIR since
661: nothing is executed from what is installed in DESTDIR.
662: (See critical utils, below.)
1.1 abs 663: Build often:
664: This keeps critical utilities current enough to not choke
665: on any other part of the source tree that depends on up to
1.123 jmc 666: date functionality. If you use build.sh, you should not have
667: this problem.
1.1 abs 668:
669: What to do if things don't work:
670: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
671: When things don't work there is usually a few things that commonly
672: should be done.
673: 1) make includes
674: This should be done automatically by make build.
675: 2) cd share/mk && make install
676: Again, automatically done by make build.
677:
678: Failsafe rebuild of a small part of the tree:
679: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
680: To make sure you rebuild something correctly you want to do
681: something like the following:
682: 1) Make sure the includes and .mk files are up to date.
683: 2) Make sure any program used to build the particular
684: utility is up to date. (yacc, lex, etc...)
685: 3) cd ...path/to/util...
686: make cleandir
687: rm ...all obj directories...
688: make cleandir # yes, again
689: make obj
690: make depend && make
691:
692: Failsafe rebuild of the entire tree:
693: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
694: If you really want to make sure the source tree is clean and
1.2 mrg 695: ready for a build try the following. Note that sourcing /etc/mk.conf
696: (a make(1) Makefile) in this manner is not right, and will not work
697: for anyone who uses any make(1) features in /etc/mk.conf.
