1.135 ! jmc 1: $NetBSD: UPDATING,v 1.134 2005/01/09 07:31:31 christos Exp $
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: ^^^^^^^^^^^^^^^
1.135 ! jmc 18: 20050211:
! 19: Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in
! 20: some of the cross tools to fail if they use configure. Some configure's
! 21: cache the environment passed in and notice the new environment is
! 22: different and abort. Doing a clean in tools/ should be enough to
! 23: make a build continue.
! 24:
1.134 christos 25: 20050109:
26: Since su is using pam by default now, make sure that you have
27: /etc/pam.d populated (postinstall will do that automatically
28: for you). Otherwise su will fail open (i.e. will not require
29: a password).
30:
1.133 christos 31: 20041229:
32: Make had a path resolution bug that manifested itself as not
33: being able to install openpam.3. This bug has been fixed, but
34: you might need to rebuild make manually first to get through
35: the build.
36:
1.130 christos 37: 20041201:
38: Userland programs have been changed to use /dev/bpf instead of
39: /dev/bpfX. You need to create that device by installing a new
1.131 wiz 40: MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]*
1.99 mrg 41:
1.129 jmc 42: 20041006:
43:
44: A bug was introduced into /bin/sh (var.c rev 1.35) which causes
45: variables to not export correctly to subshells in all cases. This
46: will cause builds to break if that version of /bin/sh is installed
47: on the system. The proper version of /bin/sh can be verified with:
48:
49: ident /bin/sh | grep var
50:
51: Any /bin/sh w. version 1.35 will not work and needs to be updated
52: before attempting a build.
53:
1.127 christos 54: 20041001:
55: The ipfilter kernel sources moved from sys/netinet to
56: dist/sys/ipf/netinet. Due to the move some Makefile
57: dependencies are now dangling requiring a make cleandir
1.128 he 58: before they work again (kdump, ktruss, rescue, ipf, and
59: ftp-proxy are the victims).
1.127 christos 60:
1.125 atatat 61: 20040715:
62: The rc.d/sendmail script now uses a heuristic to determine
63: if sendmail should be started at boot time. It checks the
64: contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
65: owner and mode of the sendmail binary to see if any changes
66: to the mail infrastructure have been made. If no changes
67: are detected, it will start an SMTP listener.
68:
69: Setting sendmail=NO in /etc/rc.conf will override this.
70:
71: If you are only using sendmail by default and only for
72: local delivery, it is important that you also update your
73: sendmail.cf so that the SMTP listener only listens on the
74: loopback interface.
75:
76: 20040715:
77: The method by which athhal-elf.o gets pulled into i386
78: kernel builds has been changed again. The latest version
79: of bsd.files.mk is no longer required.
80:
1.124 jmc 81: 20040621:
82: Due to the recent rototill of tools/compat it's crucial one starts
83: from a clean objdir under tools/*.
84:
85: This is mostly due to generated files (yacc and lex sources) needing
1.125 atatat 86: to be generated with new rules from bsd.hostprog.mk.
1.124 jmc 87:
88: The safest course is to rm -rf all objects under tools before building.
89:
1.121 lukem 90: 20040516:
91: The end-user modifiable X11 configuration has been moved
92: from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
93: Ensure that src and xsrc is up to date, and run
94: "make cleandir" in src/x11 before your next build.
95:
1.126 lukem 96: postinstall currently doesn't migrate the files from
97: /usr/X11R6/lib/X11/* to /etc/X11/* although it does
98: detect that this needs to occur, so you'll have to
99: manually move these files yourself.
100:
1.119 atatat 101: 20040426:
102: Support for the original dynamic sysctl node structure has
103: been removed in favor of the newer layout. This affects
104: consumers of the create and delete interface, as well as
105: the dynamic discovery mechanism. This is believed only to
106: be the sysctl(8) binary itself, at this point in time, so
107: the only effect of this should be that a sysctl binary
108: built from sources dated between 2003/12/04 and 2004/03/24
109: will not work on a kernel built from sources dated after
110: 2004/04/25. If you need a new sysctl binary but build.sh
111: does not work, make sure that your revision of
1.120 atatat 112: src/sys/sys/sysctl.h is 1.112 (or later), and then the
113: do the following:
1.119 atatat 114:
1.120 atatat 115: cd /usr/src (or wherever your source tree is)
116: make USETOOLS=no includes
117: cd lib/libc
118: make USETOOLS=no dependall install
119: cd ../../sbin/sysctl
1.119 atatat 120: make USETOOLS=no dependall install
121:
1.122 itojun 122: If you are using older sysctl binary, GNU autoconf would fail to
123: identify your machine architecture, and tries to build binary for
124: "unknown-unknown-netbsd20F" or something like that. if that happens,
125: make sure to follow the above steps.
126:
1.118 dbj 127: 20040425:
128: The ffs superblock issues listed below under 20040109 and 20030402
129: are now automatically addressed by the /etc/rc.d/fixsb script or by
130: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
131: invocation mentioned below will continue to work and is now
132: automated by those scripts. Note that under certain circumstances,
133: affected filesystems upgraded to a -current kernel first before
134: upgrading their userland with the fixsb and fsck_ffs fixes may
135: encounter a 'freeing free inode' panic when writing to the affected
136: filesystem, so it is a good idea to repair the filesystem as soon as
137: possible. For more details on the fixsb script, see pr install/25138.
138:
1.115 christos 139: 20040418:
1.121 lukem 140: statfs(2) and friends have been replaced with statvfs(2). Before
1.115 christos 141: installing a newly build userland make sure that you are running
142: a newly built kernel with COMPAT_20 set. In addition your libc
143: build might not work (undefined SYS_statfs symbol) because make
144: clean does not know how to remove files it does not know about
1.116 christos 145: anymore. Manually remove all generated .S sources and objects
146: from the libc build directory.
1.115 christos 147:
1.114 jmc 148: 20040326:
149: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 150: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 151: and the generated Makefile will use the new .uue rules from bsd.file.mk
152: to build it.
153:
154: This means you must have the latest bsd.files.mk installed when
155: building a kernel without USETOOLS=yes.
156:
1.113 dan 157: 20040318:
158: A bug in the cgd(4) blowfish code was corrected, without
159: provision of backwards compatibility, after several public
160: notices over several months. Users of cgd with blowfish cipher
161: ONLY must dump their data before updating their kernels, and
162: recreate cgd's and restore data using the new kernel. See
163: (recent message to current-users, URL when mail-index has updated)
164:
1.108 bjh21 165: 20040313:
166: On acorn32, the opms and qms drivers have been withdrawn, and
167: the old wsqms driver is now called qms. Kernel config files
168: will need updating. See the ones in sys/arch/acorn32/conf
169: for examples.
170:
1.106 bjh21 171: 20040125:
172: On acorn32, the beep and sysbeep devices are no longer
173: needed, and will need to be deleted from kernel configuration
174: files.
1.105 bjh21 175:
1.102 dbj 176: 20040109:
177: Compatibility for old ffs superblock layouts has been
178: added, and the restrictive fsck checks have been reenabled
179: when using those layouts. If you have been using -current
180: since 20030402, you may find that fsck again signals fatal
1.110 dbj 181: superblock mismatches. To repair, make sure you have
1.111 simonb 182: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 183: to complete the filesystem upgrade. A message has
1.111 simonb 184: been added to the kernel which should detect this problem.
185: See the following discussion for more information:
1.112 keihan 186: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 187:
1.99 mrg 188: 20031203:
1.100 keihan 189: New binutils builds may fail due to old dependencies.
1.99 mrg 190: It's necessary to "make cleandir" to ensure that
191: the dependencies will be rebuilt correctly.
1.98 wiz 192:
193: 20031111:
194: A newer mkdep is needed. Error noting that is
195: cc: Ambiguous abbreviation --
1.97 lukem 196:
197: 20031008:
198: /usr/include/sys/disklabel_mbr.h was removed.
199: It's necessary to "make cleandir" to ensure that
200: the dependencies will be rebuilt correctly.
1.96 christos 201:
1.109 dbj 202: 20031007:
1.111 simonb 203: A sign exension bug was fixed which set all the high bits
204: of our newly expanded ffs fs_flags. This should only
205: affect users who installed or upgraded in September of 2003.
1.109 dbj 206: A small utility program was posted to tech-kern which
1.111 simonb 207: should fix this problem, and a warning message was added
208: to the kernel which should discover and warn about it. See
209: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 210:
1.96 christos 211: 20030906:
212: With the addition of siginfo support the old signal trampoline
213: code has been deprecated to COMPAT_16. Make sure that your running
214: kernel has COMPAT_16 enabled before building userland.
1.94 christos 215:
216: 20030801:
1.95 wiz 217: With the new openssl, there is some header and library shuffling.
1.94 christos 218: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 219: /usr/lib/libdes* before building.
1.92 wiz 220:
221: 20030703:
222: Texinfo was updated to 4.6. To avoid failures when trying to
223: build the included texinfo files, do:
224:
225: cd src/gnu/usr.bin/texinfo
226: make MKINFO=no dependall install
1.90 wiz 227:
228: 20030630:
1.101 junyoung 229: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 230: cd share/mk && make install
1.90 wiz 231: cd src/gnu/usr.bin/groff
232: make MKMAN=no dependall install
233: (untested).
1.89 christos 234:
235: 20030516:
236: Due to bugs in the export handling code, invalid export lines
237: were accepted before and caused the kernel to panic when
238: mountd got restarted because it freed memory that had already
239: been freed. This has been fixed and the kernel checks
240: export addresses very strictly. If you upgrade your kernel,
241: make sure you also upgrade mountd, because if your export
242: file contains lines with an old inet4 address syntax (i.e.
243: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 244:
245: 20030402:
246: The superblock layout for FFS was changed. If you have 1.6
247: fsck binaries, they will signal a fatal superblock mismatch
248: with the first alternate, because they compare too many
249: fields (even ones that aren't useful). If possible, upgrade
250: your fsck_ffs binary before using a new kernel.
251: None of this signals actual filesystem damage.
1.85 atatat 252:
253: 20030324:
254: sendmail version 8.12.8 was imported. Since sendmail is
255: now setgid to the smmsp group, and runs in "collection"
256: mode for most common activities, there is a new config
257: file called submit.cf that needs to live in /etc/mail.
258: The generic submit.cf sample in /usr/share/sendmail/cf
259: is named netbsd-msp.cf. Upgrading your regular sendmail
260: configuration file is also strongly advised.
261:
262: See the section named "MESSAGE SUBMISSION PROGRAM" in
263: the updated /usr/share/sendmail/README file for more
264: information.
1.82 wiz 265:
266: 20030117:
267: Texinfo was updated to 4.3. To avoid failures when trying to
268: build the included texinfo files, do:
269:
270: cd src/gnu/usr.bin/texinfo
271: make MKINFO=no dependall install
1.81 lukem 272:
273: 20021223:
274: The METALOG format changed slightly, to remove the leading
275: "${DESTDIR}" from path names.
276: This only affects people building with UNPRIVED.
277: For complete safety, remove the DESTDIR entirely and
278: update tools/mtree, before running make build.
1.88 itojun 279:
280: 20021219:
281: CVS repository layout was changed. See the following for details
282: if you are using (anonymous) cvs to update your tree.
283:
1.93 salo 284: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 285:
286: 20021219:
287: install(1) had a '-N dbdir' option added, to specify an
288: alternate location to look up users & groups (instead
289: of the host system passwd(5) and group(5) databases).
290:
291: The build system was modified to take advantage of
292: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 293: use USETOOLS==no, you may have to rebuild and
1.80 lukem 294: reinstall usr.bin/xinstall first.
1.78 lukem 295:
296: 20021130:
297: fparseln(3) moved from libutil to libc.
298: If building to DESTDIR=/, reinstall the includes
299: and rebuild libc:
300: make includes
301: make do-lib-libc
302: If using build.sh, "cd tools/compat && make clean"
303: before rebuilding the tools.
1.77 lukem 304:
305: 20021126:
306: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
307: including the optional "SYS_INCLUDE=symlinks" support.
308: All header files, including <sys/*.h> are copied into
309: /usr/include.
1.76 thorpej 310:
311: 20021121:
312: The C run-time support files crtbegin.o and crtend.o
313: (and their companions crtbeginS.o and crtendS.o) were
314: split up, with new crti.o and crtn.o files resulting.
315: This means that libtool needs to be rebuilt once the
316: new libraries are installed. The process of rebuilding
317: libtool will cause it to automatically notice the new
318: required files, but it *must* be rebuilt in order to
319: do this.
320:
321: An out-of-date libtool will result in shared libraries
322: which lack _init() and _fini() routines, which means that
323: their global contructors/destructors will not be invoked.
1.75 thorpej 324:
325: 20021121:
326: A bug related to how ARM ELF objects were tagged has been
327: corrected.
328:
329: NetBSD ARM ELF uses the soft-VFP floating point model by
330: default. However, the assembler lacked support for marking
331: objects as using the VFP floating point format, and the
1.79 wiz 332: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 333: to the assembler.
334:
335: Unfortunately, this means that the linker will now consider
336: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
337: incompatible with new (properly marked) objects.
338:
339: The problem will only manifest itself if you attempt to compile
340: a new program using the fixed toolchain, and link that program
341: against old libraries which do not have the proper "softvfp"
342: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
343: WILL CONTINUE TO WORK PROPERLY.
344:
345: The only work-around for the problem is to recompile all of
346: the libraries on the system. The easiest way to do this for
1.79 wiz 347: system libraries is to install a binary snapshot; they are
1.93 salo 348: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 349: have installed which supply libraries will have to be recompiled
350: if you wish to link new programs against those libraries.
351:
352: If you have questions about this matter, please contact
1.93 salo 353: port-arm@NetBSD.org.
1.73 provos 354:
355: 20021011:
356: Systrace has been improved to support privilege elevation.
357: Updating the kernel requires the userland part of systrace
1.79 wiz 358: to be rebuilt.
1.72 thorpej 359:
360: 20021010:
361: The config(8) grammar was changed to allow options to register
362: dependencies on attributes, as well as other options. Users
363: must update and reinstall usr.sbin/config before building a new
364: kernel.
1.70 thorpej 365:
366: 20021009:
367: A new attribute dependency syntax was introduced to config(8),
368: which is now used by the SCSI configuration description. Users
1.71 wiz 369: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 370: kernel.
1.69 thorpej 371:
372: 20021003:
373: Several changes have been made to the autoconfiguration
374: framework. Users must update and reinstall usr.sbin/config
375: before building a new kernel.
1.74 jschauma 376:
377: 20021001:
378: The i386mp branch has been merged. To compile a kernel, users
379: will need to add the option 'cpu* at mainbus?' to their configuration
380: file. Multiprocessor kernels will need
381: ioapic* at mainbus? apid ?
382: options MULTIPROCESSOR
383: options COM_MPLOCK
1.68 lukem 384:
385: 20020922:
386: MKDYNAMICROOT=yes enabled by default, which means that
387: certain shared libraries are installed into /lib, the shared
388: linker is installed into /libexec, and all programs in /bin
389: and /sbin are dynamically linked.
390: If you do not use "make build", you should ensure that
391: you have the libraries and shared linker in the new locations,
392: with:
393: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 394:

396: USE_NEW_TOOLCHAIN has been replaced with:
397: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
398: there is no working in-tree toolchain (hppa, ns32k, sh5,
399: x86_64).
400: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 401: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 402: enables the cross-build framework even for TOOLCHAIN_MISSING
403: platforms.
1.66 gehenna 404:
405: 20020906:
406: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 407: reinstall usr.sbin/config before building the kernel.

410: Crunched rescue tools (contents of /bin and /sbin, plus others)
411: are now provided in /rescue.
412:
413: To ensure that these are built statically linked (no matter
414: what the setting of LDSTATIC is), use a crunchgen(1) built
415: from sources newer than 20020820 (see the next entry).
416:
417: 20020820:
418: crunchgen(1) changed to ensure that the generated program
419: is statically linked.

453: etc/postinstall added, which performs various checks for
454: configuration file updates and changes, and can fix most of
455: the problems identified.
456: This should make it much easier to upgrade a system's
457: configuration from earlier systems (as far back as NetBSD 1.5).

491: If you're attempting to build a snapshot on sparc64 and are getting
492: reloc errors from the toolchain groff binary this means your native
493: toolchain has some broken C++ bits.
494:
495: To fix:
496:
497: Build a new toolchain (i.e. build.sh -t)
498: Use the new toolchain to build and install natively (i.e. /usr/lib)
499:
500: gnu/lib/libgcc

529: The new document BUILDING.mdoc (view with nroff | more, or
530: see pre-generated .txt and .html versions) describes the build
531: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
532: build process, are intended in the long run to replace this
533: manual update log.
534:
535: Users building a USE_NEW_TOOLCHAIN system should read the
536: BUILDING document for caveats. Generally, BUILDING supersedes
537: UPDATING for these systems, as tool updating is taken care of
538: by the new build system.

566: directories.
1.31 enami 567:
568: 20010803:
569: grep.info is now built from grep.texi using makeinfo. Since it
570: requires makeinfo v4.0, you need to install new texinfo before

572: the instruction described in 20010726 entry.
1.30 enami 573:
1.64 sommerfe 574: 20010803:
1.41 wiz 575: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 576: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 577: kernel successfully, you need to build and install a new toolchain,
578: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
579: from your kernel configuration until you rebuild your userland.
580: See 20011029 above and BUILDING file in this directory for more information.
581: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]

596: Enabled correct .init/.fini processing in crt0. The way this
597: was done was to change a -I directive to cc(1), which means
598: make(1) will have a stale dependency (it will be checking the
599: timestamp on the wrong "dot_init.h").
600:
601: The symptom you will see is that new programs die with SIGSEGV
602: if you have a stale dependency.
603:
604: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
605: before starting your build.
1.26 thorpej 606:
607: 20010628:

610: bitfield, update your lint(1) before proceeding.
1.21 jmc 611:

640: particular start eliminating redundant declarations. Yacc
641: needs to be installed before make build.
1.10 christos 642:
643: 20010114:
644: introduce .if commands(target) in make(1). You need to
645: bring everything up-to-date first, then without installing
1.23 tron 646: anything make and install in usr.bin/make, then proceed
1.10 christos 647: with make build.
1.9 sommerfe 648:
649: 20010101:
650: bsd.subdir.mk committed 20001230 had a bug which caused
651: afterinstall targets to run too soon; update again.
1.8 sommerfe 652:
653: 20001230:
654: New share/mk files needed to support .WAIT in SUBDIR variables.
655: If you get make errors,
656: (cd share/mk; make install)
657: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 658:
659: 20001019:
1.7 ad 660: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 661: major and minor numbers haven't changed, you should update your /dev
662: directory.
1.1 abs 663:
1.4 itojun 664: 20000929:
665: The following make directives are obsoleted.
666: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
667: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 668: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 669: additional library libcrypto_{idea,rc5}.
1.1 abs 670:
671:
672: Hints for a more successful build:
673: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 674: Use build.sh, but do not use its "expert mode":
1.132 jmmv 675: This will automatically build the tools in the
1.123 jmc 676: correct order, and it will keep the tools and the
677: new build products from interfering with the running
678: system. This will allow you to ignore most of the
679: other advice in this file.
1.2 mrg 680: Build a new kernel first:
681: This makes sure that any new system calls or features
682: expected by the new userland will be present. This
683: helps to avoid critical errors when upgrading.
1.1 abs 684: Use object directories:
685: This helps to keep stale object
686: files from polluting the build if a Makefile "forgets"
687: about one. It also makes it easier to clean up after
688: a build. It's also necessary if you want to use the
689: same source tree for multiple machines.
1.123 jmc 690: To use object directories with build.sh:
691: a) invoke build.sh with the "-M" or "-O" options.
692: To use object directories without using build.sh:
1.1 abs 693: a) cd /usr/src ; make cleandir
1.2 mrg 694: b) Add "OBJMACHINE=yes" to /etc/mk.conf
695: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 696: d) cd /usr/src ; make build
1.2 mrg 697: Note that running "make obj" in a directory will create
698: in obj.$MACHINE directory.
1.1 abs 699: Build to a DESTDIR:
1.123 jmc 700: This helps to keep old installed files (especially libraries)
701: from interfering with the new build.
702: To build to a DESTDIR with build.sh, use the "-D" option.
703: To build to a DESTDIR without using build.sh, set the DESTDIR
704: environment variable before running make build. It should be
705: set to the pathname of an initially empty directory.
706: Problems: if you do not use build.sh, you might need to
707: update critical utilities without using DESTDIR since
708: nothing is executed from what is installed in DESTDIR.
709: (See critical utils, below.)
1.1 abs 710: Build often:
711: This keeps critical utilities current enough to not choke
712: on any other part of the source tree that depends on up to
1.123 jmc 713: date functionality. If you use build.sh, you should not have
714: this problem.
1.1 abs 715:
716: What to do if things don't work:
717: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
718: When things don't work there is usually a few things that commonly
719: should be done.
720: 1) make includes
721: This should be done automatically by make build.
722: 2) cd share/mk && make install
723: Again, automatically done by make build.
724:
725: Failsafe rebuild of a small part of the tree:
726: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
727: To make sure you rebuild something correctly you want to do
728: something like the following:
729: 1) Make sure the includes and .mk files are up to date.
730: 2) Make sure any program used to build the particular
731: utility is up to date. (yacc, lex, etc...)
732: 3) cd ...path/to/util...
733: make cleandir
734: rm ...all obj directories...
735: make cleandir # yes, again
736: make obj
737: make depend && make
738:
739: Failsafe rebuild of the entire tree:
740: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
741: If you really want to make sure the source tree is clean and
1.2 mrg 742: ready for a build try the following. Note that sourcing /etc/mk.conf
743: (a make(1) Makefile) in this manner is not right, and will not work
744: for anyone who uses any make(1) features in /etc/mk.conf.
