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.

20: The end-user modifiable X11 configuration has been moved
21: from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
22: Ensure that src and xsrc is up to date, and run
23: "make cleandir" in src/x11 before your next build.

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

371: the build process).
1.60 sommerfe 372:

374: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 375:
376: 20020426:
377: etc/postinstall added, which performs various checks for
378: configuration file updates and changes, and can fix most of
379: the problems identified.
380: This should make it much easier to upgrade a system's
381: configuration from earlier systems (as far back as NetBSD 1.5).

389: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 390: newer than November 2001 when you upgrade the kernel.
391:
1.54 itojun 392: 20020311:
393: ssh configuration files were moved from /etc to /etc/ssh. Beware
394: if you restart your machine from remote. Note that sshd.conf needs
395: to be changed (due to the use of "/etc" inside).
396:
397: 20020223:
1.53 matt 398: Users of the VAX port will need to rebuild and install gas
399: so it deal with the now present register prefix used in all
400: the VAX assembly files.

1.50 itojun 402: 20020118:
403: ntpd user/group has been added. Need to hand add this in or builds
404: will break as mtree aborts early.
405:

415: If you're attempting to build a snapshot on sparc64 and are getting
416: reloc errors from the toolchain groff binary this means your native
417: toolchain has some broken C++ bits.
418:
419: To fix:
420:
421: Build a new toolchain (i.e. build.sh -t)
422: Use the new toolchain to build and install natively (i.e. /usr/lib)
423:
424: gnu/lib/libgcc

1.47 jmc 429: 20011201:
430: In order for a sparc64 build to work you must have a working awk. If
431: you've built and installed a system with the new toolchain up to this
1.52 wiz 432: point you do not have a working awk as its ability to do floating
1.47 jmc 433: point is broken.
434:
435: To build:

453: The new document BUILDING.mdoc (view with nroff | more, or
454: see pre-generated .txt and .html versions) describes the build
455: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
456: build process, are intended in the long run to replace this
457: manual update log.
458:
459: Users building a USE_NEW_TOOLCHAIN system should read the
460: BUILDING document for caveats. Generally, BUILDING supersedes
461: UPDATING for these systems, as tool updating is taken care of
462: by the new build system.

466: symlinks that point to nowhere. A bug in install that
467: prevented this was corrected.
468:

470: Better Solution: Use the new toolchain and it will just work
471: for you.

1.30 enami 497:
1.64 sommerfe 498: 20010803:
1.41 wiz 499: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 500: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 501: kernel successfully, you need to build and install a new toolchain,
502: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
503: from your kernel configuration until you rebuild your userland.
504: See 20011029 above and BUILDING file in this directory for more information.

520: Enabled correct .init/.fini processing in crt0. The way this
521: was done was to change a -I directive to cc(1), which means
522: make(1) will have a stale dependency (it will be checking the
523: timestamp on the wrong "dot_init.h").
524:
525: The symptom you will see is that new programs die with SIGSEGV
526: if you have a stale dependency.
527:
528: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
529: before starting your build.
1.26 thorpej 530:
531: 20010628:

1.10 christos 571: with make build.

1.1 abs 594:

596: Hints for a more successful build:
597: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 ! jmc 598: Use build.sh, but do not use its "expert mode":
! 599: This will will automatically build the tools in the
! 600: correct order, and it will keep the tools and the
! 601: new build products from interfering with the running
! 602: system. This will allow you to ignore most of the
! 603: other advice in this file.
1.2 mrg 604: Build a new kernel first:
605: This makes sure that any new system calls or features
606: expected by the new userland will be present. This
607: helps to avoid critical errors when upgrading.
1.1 abs 608: Use object directories:
609: This helps to keep stale object
610: files from polluting the build if a Makefile "forgets"
611: about one. It also makes it easier to clean up after
612: a build. It's also necessary if you want to use the
613: same source tree for multiple machines.
1.123 ! jmc 614: To use object directories with build.sh:
! 615: a) invoke build.sh with the "-M" or "-O" options.
! 616: To use object directories without using build.sh:
1.1 abs 617: a) cd /usr/src ; make cleandir
1.2 mrg 618: b) Add "OBJMACHINE=yes" to /etc/mk.conf
619: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 620: d) cd /usr/src ; make build
1.2 mrg 621: Note that running "make obj" in a directory will create
622: in obj.$MACHINE directory.
1.1 abs 623: Build to a DESTDIR:
1.123 ! jmc 624: This helps to keep old installed files (especially libraries)
! 625: from interfering with the new build.
! 626: To build to a DESTDIR with build.sh, use the "-D" option.
! 627: To build to a DESTDIR without using build.sh, set the DESTDIR
! 628: environment variable before running make build. It should be
! 629: set to the pathname of an initially empty directory.
! 630: Problems: if you do not use build.sh, you might need to
! 631: update critical utilities without using DESTDIR since
! 632: nothing is executed from what is installed in DESTDIR.
! 633: (See critical utils, below.)
1.1 abs 634: Build often:
635: This keeps critical utilities current enough to not choke
636: on any other part of the source tree that depends on up to
1.123 ! jmc 637: date functionality. If you use build.sh, you should not have
! 638: this problem.
1.1 abs 639:
640: What to do if things don't work:
641: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
642: When things don't work there is usually a few things that commonly
643: should be done.
644: 1) make includes
645: This should be done automatically by make build.
646: 2) cd share/mk && make install
647: Again, automatically done by make build.
648:
649: Failsafe rebuild of a small part of the tree:
650: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
651: To make sure you rebuild something correctly you want to do
652: something like the following:
653: 1) Make sure the includes and .mk files are up to date.
654: 2) Make sure any program used to build the particular
655: utility is up to date. (yacc, lex, etc...)
656: 3) cd ...path/to/util...
657: make cleandir
658: rm ...all obj directories...
659: make cleandir # yes, again
660: make obj
661: make depend && make
662:
663: Failsafe rebuild of the entire tree:
664: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
665: If you really want to make sure the source tree is clean and
1.2 mrg 666: ready for a build try the following. Note that sourcing /etc/mk.conf
667: (a make(1) Makefile) in this manner is not right, and will not work
