Annotation of src/UPDATING, Revision 1.135.2.1
1.135.2.1! tron 1: $NetBSD$
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: ^^^^^^^^^^^^^^^
1.135.2.1! tron 18:
! 19: 20050417:
! 20: postinstall(8) was moved from /etc to /usr/sbin and made part
! 21: of the "base" set, to make it easier to invoke after an
! 22: upgrade.
! 23:
1.135 jmc 24: 20050211:
25: Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in
26: some of the cross tools to fail if they use configure. Some configure's
27: cache the environment passed in and notice the new environment is
28: different and abort. Doing a clean in tools/ should be enough to
29: make a build continue.
30:
1.134 christos 31: 20050109:
32: Since su is using pam by default now, make sure that you have
33: /etc/pam.d populated (postinstall will do that automatically
34: for you). Otherwise su will fail open (i.e. will not require
35: a password).
36:
1.133 christos 37: 20041229:
38: Make had a path resolution bug that manifested itself as not
39: being able to install openpam.3. This bug has been fixed, but
40: you might need to rebuild make manually first to get through
41: the build.
42:
1.130 christos 43: 20041201:
44: Userland programs have been changed to use /dev/bpf instead of
45: /dev/bpfX. You need to create that device by installing a new
1.131 wiz 46: MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]*
1.99 mrg 47:
1.129 jmc 48: 20041006:
49:
50: A bug was introduced into /bin/sh (var.c rev 1.35) which causes
51: variables to not export correctly to subshells in all cases. This
52: will cause builds to break if that version of /bin/sh is installed
53: on the system. The proper version of /bin/sh can be verified with:
54:
55: ident /bin/sh | grep var
56:
57: Any /bin/sh w. version 1.35 will not work and needs to be updated
58: before attempting a build.
59:
1.127 christos 60: 20041001:
61: The ipfilter kernel sources moved from sys/netinet to
62: dist/sys/ipf/netinet. Due to the move some Makefile
63: dependencies are now dangling requiring a make cleandir
1.128 he 64: before they work again (kdump, ktruss, rescue, ipf, and
65: ftp-proxy are the victims).
1.127 christos 66:
1.125 atatat 67: 20040715:
68: The rc.d/sendmail script now uses a heuristic to determine
69: if sendmail should be started at boot time. It checks the
70: contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
71: owner and mode of the sendmail binary to see if any changes
72: to the mail infrastructure have been made. If no changes
73: are detected, it will start an SMTP listener.
74:
75: Setting sendmail=NO in /etc/rc.conf will override this.
76:
77: If you are only using sendmail by default and only for
78: local delivery, it is important that you also update your
79: sendmail.cf so that the SMTP listener only listens on the
80: loopback interface.
81:
82: 20040715:
83: The method by which athhal-elf.o gets pulled into i386
84: kernel builds has been changed again. The latest version
85: of bsd.files.mk is no longer required.
86:
1.124 jmc 87: 20040621:
88: Due to the recent rototill of tools/compat it's crucial one starts
89: from a clean objdir under tools/*.
90:
91: This is mostly due to generated files (yacc and lex sources) needing
1.125 atatat 92: to be generated with new rules from bsd.hostprog.mk.
1.124 jmc 93:
94: The safest course is to rm -rf all objects under tools before building.
95:
1.121 lukem 96: 20040516:
97: The end-user modifiable X11 configuration has been moved
98: from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
99: Ensure that src and xsrc is up to date, and run
100: "make cleandir" in src/x11 before your next build.
101:
1.126 lukem 102: postinstall currently doesn't migrate the files from
103: /usr/X11R6/lib/X11/* to /etc/X11/* although it does
104: detect that this needs to occur, so you'll have to
105: manually move these files yourself.
106:
1.119 atatat 107: 20040426:
108: Support for the original dynamic sysctl node structure has
109: been removed in favor of the newer layout. This affects
110: consumers of the create and delete interface, as well as
111: the dynamic discovery mechanism. This is believed only to
112: be the sysctl(8) binary itself, at this point in time, so
113: the only effect of this should be that a sysctl binary
114: built from sources dated between 2003/12/04 and 2004/03/24
115: will not work on a kernel built from sources dated after
116: 2004/04/25. If you need a new sysctl binary but build.sh
117: does not work, make sure that your revision of
1.120 atatat 118: src/sys/sys/sysctl.h is 1.112 (or later), and then the
119: do the following:
1.119 atatat 120:
1.120 atatat 121: cd /usr/src (or wherever your source tree is)
122: make USETOOLS=no includes
123: cd lib/libc
124: make USETOOLS=no dependall install
125: cd ../../sbin/sysctl
1.119 atatat 126: make USETOOLS=no dependall install
127:
1.122 itojun 128: If you are using older sysctl binary, GNU autoconf would fail to
129: identify your machine architecture, and tries to build binary for
130: "unknown-unknown-netbsd20F" or something like that. if that happens,
131: make sure to follow the above steps.
132:
1.118 dbj 133: 20040425:
134: The ffs superblock issues listed below under 20040109 and 20030402
135: are now automatically addressed by the /etc/rc.d/fixsb script or by
136: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
137: invocation mentioned below will continue to work and is now
138: automated by those scripts. Note that under certain circumstances,
139: affected filesystems upgraded to a -current kernel first before
140: upgrading their userland with the fixsb and fsck_ffs fixes may
141: encounter a 'freeing free inode' panic when writing to the affected
142: filesystem, so it is a good idea to repair the filesystem as soon as
143: possible. For more details on the fixsb script, see pr install/25138.
144:
1.115 christos 145: 20040418:
1.121 lukem 146: statfs(2) and friends have been replaced with statvfs(2). Before
1.115 christos 147: installing a newly build userland make sure that you are running
148: a newly built kernel with COMPAT_20 set. In addition your libc
149: build might not work (undefined SYS_statfs symbol) because make
150: clean does not know how to remove files it does not know about
1.116 christos 151: anymore. Manually remove all generated .S sources and objects
152: from the libc build directory.
1.115 christos 153:
1.114 jmc 154: 20040326:
155: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 156: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 157: and the generated Makefile will use the new .uue rules from bsd.file.mk
158: to build it.
159:
160: This means you must have the latest bsd.files.mk installed when
161: building a kernel without USETOOLS=yes.
162:
1.113 dan 163: 20040318:
164: A bug in the cgd(4) blowfish code was corrected, without
165: provision of backwards compatibility, after several public
166: notices over several months. Users of cgd with blowfish cipher
167: ONLY must dump their data before updating their kernels, and
168: recreate cgd's and restore data using the new kernel. See
169: (recent message to current-users, URL when mail-index has updated)
170:
1.108 bjh21 171: 20040313:
172: On acorn32, the opms and qms drivers have been withdrawn, and
173: the old wsqms driver is now called qms. Kernel config files
174: will need updating. See the ones in sys/arch/acorn32/conf
175: for examples.
176:
1.106 bjh21 177: 20040125:
178: On acorn32, the beep and sysbeep devices are no longer
179: needed, and will need to be deleted from kernel configuration
180: files.
1.105 bjh21 181:
1.102 dbj 182: 20040109:
183: Compatibility for old ffs superblock layouts has been
184: added, and the restrictive fsck checks have been reenabled
185: when using those layouts. If you have been using -current
186: since 20030402, you may find that fsck again signals fatal
1.110 dbj 187: superblock mismatches. To repair, make sure you have
1.111 simonb 188: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 189: to complete the filesystem upgrade. A message has
1.111 simonb 190: been added to the kernel which should detect this problem.
191: See the following discussion for more information:
1.112 keihan 192: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 193:
1.99 mrg 194: 20031203:
1.100 keihan 195: New binutils builds may fail due to old dependencies.
1.99 mrg 196: It's necessary to "make cleandir" to ensure that
197: the dependencies will be rebuilt correctly.
1.98 wiz 198:
199: 20031111:
200: A newer mkdep is needed. Error noting that is
201: cc: Ambiguous abbreviation --
1.97 lukem 202:
203: 20031008:
204: /usr/include/sys/disklabel_mbr.h was removed.
205: It's necessary to "make cleandir" to ensure that
206: the dependencies will be rebuilt correctly.
1.96 christos 207:
1.109 dbj 208: 20031007:
1.111 simonb 209: A sign exension bug was fixed which set all the high bits
210: of our newly expanded ffs fs_flags. This should only
211: affect users who installed or upgraded in September of 2003.
1.109 dbj 212: A small utility program was posted to tech-kern which
1.111 simonb 213: should fix this problem, and a warning message was added
214: to the kernel which should discover and warn about it. See
215: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 216:
1.96 christos 217: 20030906:
218: With the addition of siginfo support the old signal trampoline
219: code has been deprecated to COMPAT_16. Make sure that your running
220: kernel has COMPAT_16 enabled before building userland.
1.94 christos 221:
222: 20030801:
1.95 wiz 223: With the new openssl, there is some header and library shuffling.
1.94 christos 224: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 225: /usr/lib/libdes* before building.
1.92 wiz 226:
227: 20030703:
228: Texinfo was updated to 4.6. To avoid failures when trying to
229: build the included texinfo files, do:
230:
231: cd src/gnu/usr.bin/texinfo
232: make MKINFO=no dependall install
1.90 wiz 233:
234: 20030630:
1.101 junyoung 235: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 236: cd share/mk && make install
1.90 wiz 237: cd src/gnu/usr.bin/groff
238: make MKMAN=no dependall install
239: (untested).
1.89 christos 240:
241: 20030516:
242: Due to bugs in the export handling code, invalid export lines
243: were accepted before and caused the kernel to panic when
244: mountd got restarted because it freed memory that had already
245: been freed. This has been fixed and the kernel checks
246: export addresses very strictly. If you upgrade your kernel,
247: make sure you also upgrade mountd, because if your export
248: file contains lines with an old inet4 address syntax (i.e.
249: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 250:
251: 20030402:
252: The superblock layout for FFS was changed. If you have 1.6
253: fsck binaries, they will signal a fatal superblock mismatch
254: with the first alternate, because they compare too many
255: fields (even ones that aren't useful). If possible, upgrade
256: your fsck_ffs binary before using a new kernel.
257: None of this signals actual filesystem damage.
1.85 atatat 258:
259: 20030324:
260: sendmail version 8.12.8 was imported. Since sendmail is
261: now setgid to the smmsp group, and runs in "collection"
262: mode for most common activities, there is a new config
263: file called submit.cf that needs to live in /etc/mail.
264: The generic submit.cf sample in /usr/share/sendmail/cf
265: is named netbsd-msp.cf. Upgrading your regular sendmail
266: configuration file is also strongly advised.
267:
268: See the section named "MESSAGE SUBMISSION PROGRAM" in
269: the updated /usr/share/sendmail/README file for more
270: information.
1.82 wiz 271:
272: 20030117:
273: Texinfo was updated to 4.3. To avoid failures when trying to
274: build the included texinfo files, do:
275:
276: cd src/gnu/usr.bin/texinfo
277: make MKINFO=no dependall install
1.81 lukem 278:
279: 20021223:
280: The METALOG format changed slightly, to remove the leading
281: "${DESTDIR}" from path names.
282: This only affects people building with UNPRIVED.
283: For complete safety, remove the DESTDIR entirely and
284: update tools/mtree, before running make build.
1.88 itojun 285:
286: 20021219:
287: CVS repository layout was changed. See the following for details
288: if you are using (anonymous) cvs to update your tree.
289:
1.93 salo 290: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 291:
292: 20021219:
293: install(1) had a '-N dbdir' option added, to specify an
294: alternate location to look up users & groups (instead
295: of the host system passwd(5) and group(5) databases).
296:
297: The build system was modified to take advantage of
298: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 299: use USETOOLS==no, you may have to rebuild and
1.80 lukem 300: reinstall usr.bin/xinstall first.
1.78 lukem 301:
302: 20021130:
303: fparseln(3) moved from libutil to libc.
304: If building to DESTDIR=/, reinstall the includes
305: and rebuild libc:
306: make includes
307: make do-lib-libc
308: If using build.sh, "cd tools/compat && make clean"
309: before rebuilding the tools.
1.77 lukem 310:
311: 20021126:
312: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
313: including the optional "SYS_INCLUDE=symlinks" support.
314: All header files, including <sys/*.h> are copied into
315: /usr/include.
1.76 thorpej 316:
317: 20021121:
318: The C run-time support files crtbegin.o and crtend.o
319: (and their companions crtbeginS.o and crtendS.o) were
320: split up, with new crti.o and crtn.o files resulting.
321: This means that libtool needs to be rebuilt once the
322: new libraries are installed. The process of rebuilding
323: libtool will cause it to automatically notice the new
324: required files, but it *must* be rebuilt in order to
325: do this.
326:
327: An out-of-date libtool will result in shared libraries
328: which lack _init() and _fini() routines, which means that
329: their global contructors/destructors will not be invoked.
1.75 thorpej 330:
331: 20021121:
332: A bug related to how ARM ELF objects were tagged has been
333: corrected.
334:
335: NetBSD ARM ELF uses the soft-VFP floating point model by
336: default. However, the assembler lacked support for marking
337: objects as using the VFP floating point format, and the
1.79 wiz 338: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 339: to the assembler.
340:
341: Unfortunately, this means that the linker will now consider
342: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
343: incompatible with new (properly marked) objects.
344:
345: The problem will only manifest itself if you attempt to compile
346: a new program using the fixed toolchain, and link that program
347: against old libraries which do not have the proper "softvfp"
348: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
349: WILL CONTINUE TO WORK PROPERLY.
350:
351: The only work-around for the problem is to recompile all of
352: the libraries on the system. The easiest way to do this for
1.79 wiz 353: system libraries is to install a binary snapshot; they are
1.93 salo 354: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 355: have installed which supply libraries will have to be recompiled
356: if you wish to link new programs against those libraries.
357:
358: If you have questions about this matter, please contact
1.93 salo 359: port-arm@NetBSD.org.
1.73 provos 360:
361: 20021011:
362: Systrace has been improved to support privilege elevation.
363: Updating the kernel requires the userland part of systrace
1.79 wiz 364: to be rebuilt.
1.72 thorpej 365:
366: 20021010:
367: The config(8) grammar was changed to allow options to register
368: dependencies on attributes, as well as other options. Users
369: must update and reinstall usr.sbin/config before building a new
370: kernel.
1.70 thorpej 371:
372: 20021009:
373: A new attribute dependency syntax was introduced to config(8),
374: which is now used by the SCSI configuration description. Users
1.71 wiz 375: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 376: kernel.
1.69 thorpej 377:
378: 20021003:
379: Several changes have been made to the autoconfiguration
380: framework. Users must update and reinstall usr.sbin/config
381: before building a new kernel.
1.74 jschauma 382:
383: 20021001:
384: The i386mp branch has been merged. To compile a kernel, users
385: will need to add the option 'cpu* at mainbus?' to their configuration
386: file. Multiprocessor kernels will need
387: ioapic* at mainbus? apid ?
388: options MULTIPROCESSOR
389: options COM_MPLOCK
1.68 lukem 390:
391: 20020922:
392: MKDYNAMICROOT=yes enabled by default, which means that
393: certain shared libraries are installed into /lib, the shared
394: linker is installed into /libexec, and all programs in /bin
395: and /sbin are dynamically linked.
396: If you do not use "make build", you should ensure that
397: you have the libraries and shared linker in the new locations,
398: with:
399: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so

402: USE_NEW_TOOLCHAIN has been replaced with:
403: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
404: there is no working in-tree toolchain (hppa, ns32k, sh5,
405: x86_64).
406: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 407: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 408: enables the cross-build framework even for TOOLCHAIN_MISSING
409: platforms.
1.66 gehenna 410:
411: 20020906:
412: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 413: reinstall usr.sbin/config before building the kernel.

416: Crunched rescue tools (contents of /bin and /sbin, plus others)
417: are now provided in /rescue.
418:
419: To ensure that these are built statically linked (no matter
420: what the setting of LDSTATIC is), use a crunchgen(1) built
421: from sources newer than 20020820 (see the next entry).
422:
423: 20020820:
424: crunchgen(1) changed to ensure that the generated program
425: is statically linked.

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

497: If you're attempting to build a snapshot on sparc64 and are getting
498: reloc errors from the toolchain groff binary this means your native
499: toolchain has some broken C++ bits.
500:
501: To fix:
502:
503: Build a new toolchain (i.e. build.sh -t)
504: Use the new toolchain to build and install natively (i.e. /usr/lib)
505:
506: gnu/lib/libgcc

535: The new document BUILDING.mdoc (view with nroff | more, or
536: see pre-generated .txt and .html versions) describes the build
537: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
538: build process, are intended in the long run to replace this
539: manual update log.
540:
541: Users building a USE_NEW_TOOLCHAIN system should read the
542: BUILDING document for caveats. Generally, BUILDING supersedes
543: UPDATING for these systems, as tool updating is taken care of
544: by the new build system.

578: the instruction described in 20010726 entry.
1.30 enami 579:
1.64 sommerfe 580: 20010803:
1.41 wiz 581: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 582: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 583: kernel successfully, you need to build and install a new toolchain,
584: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
585: from your kernel configuration until you rebuild your userland.
586: See 20011029 above and BUILDING file in this directory for more information.
587: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]

602: Enabled correct .init/.fini processing in crt0. The way this
603: was done was to change a -I directive to cc(1), which means
604: make(1) will have a stale dependency (it will be checking the
605: timestamp on the wrong "dot_init.h").
606:
607: The symptom you will see is that new programs die with SIGSEGV
608: if you have a stale dependency.
609:
610: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
611: before starting your build.
1.26 thorpej 612:
613: 20010628:

616: bitfield, update your lint(1) before proceeding.
1.21 jmc 617:

647: needs to be installed before make build.
1.10 christos 648:
649: 20010114:
650: introduce .if commands(target) in make(1). You need to
651: bring everything up-to-date first, then without installing
1.23 tron 652: anything make and install in usr.bin/make, then proceed
1.10 christos 653: with make build.
1.9 sommerfe 654:

657: afterinstall targets to run too soon; update again.
1.8 sommerfe 658:
659: 20001230:
660: New share/mk files needed to support .WAIT in SUBDIR variables.
661: If you get make errors,
662: (cd share/mk; make install)
663: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 664:
665: 20001019:
1.7 ad 666: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 667: major and minor numbers haven't changed, you should update your /dev
668: directory.
1.1 abs 669:
1.4 itojun 670: 20000929:
671: The following make directives are obsoleted.
672: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
673: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 674: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 675: additional library libcrypto_{idea,rc5}.
1.1 abs 676:
677:
678: Hints for a more successful build:
679: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 680: Use build.sh, but do not use its "expert mode":
1.132 jmmv 681: This will automatically build the tools in the
1.123 jmc 682: correct order, and it will keep the tools and the
683: new build products from interfering with the running
684: system. This will allow you to ignore most of the
685: other advice in this file.
1.2 mrg 686: Build a new kernel first:
687: This makes sure that any new system calls or features
688: expected by the new userland will be present. This
689: helps to avoid critical errors when upgrading.
1.1 abs 690: Use object directories:
691: This helps to keep stale object
692: files from polluting the build if a Makefile "forgets"
693: about one. It also makes it easier to clean up after
694: a build. It's also necessary if you want to use the
695: same source tree for multiple machines.
1.123 jmc 696: To use object directories with build.sh:
697: a) invoke build.sh with the "-M" or "-O" options.
698: To use object directories without using build.sh:
1.1 abs 699: a) cd /usr/src ; make cleandir
1.2 mrg 700: b) Add "OBJMACHINE=yes" to /etc/mk.conf
701: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 702: d) cd /usr/src ; make build
1.2 mrg 703: Note that running "make obj" in a directory will create
704: in obj.$MACHINE directory.
1.1 abs 705: Build to a DESTDIR:
1.123 jmc 706: This helps to keep old installed files (especially libraries)
707: from interfering with the new build.
708: To build to a DESTDIR with build.sh, use the "-D" option.
709: To build to a DESTDIR without using build.sh, set the DESTDIR
710: environment variable before running make build. It should be
711: set to the pathname of an initially empty directory.
712: Problems: if you do not use build.sh, you might need to
713: update critical utilities without using DESTDIR since
714: nothing is executed from what is installed in DESTDIR.
715: (See critical utils, below.)
1.1 abs 716: Build often:
717: This keeps critical utilities current enough to not choke
718: on any other part of the source tree that depends on up to
1.123 jmc 719: date functionality. If you use build.sh, you should not have
720: this problem.
1.1 abs 721:
722: What to do if things don't work:
723: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
724: When things don't work there is usually a few things that commonly
725: should be done.
726: 1) make includes
727: This should be done automatically by make build.
728: 2) cd share/mk && make install
729: Again, automatically done by make build.
730:
731: Failsafe rebuild of a small part of the tree:
732: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
733: To make sure you rebuild something correctly you want to do
734: something like the following:
735: 1) Make sure the includes and .mk files are up to date.
736: 2) Make sure any program used to build the particular
737: utility is up to date. (yacc, lex, etc...)
738: 3) cd ...path/to/util...
739: make cleandir
740: rm ...all obj directories...
741: make cleandir # yes, again
742: make obj
743: make depend && make
744:
745: Failsafe rebuild of the entire tree:
746: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
747: If you really want to make sure the source tree is clean and
1.2 mrg 748: ready for a build try the following. Note that sourcing /etc/mk.conf
749: (a make(1) Makefile) in this manner is not right, and will not work
750: for anyone who uses any make(1) features in /etc/mk.conf.
