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

1.61 itojun 350:
1.79 wiz 351: Also /var/chroot/sshd directory needs to be present (digged as part of
352: the build process).
1.60 sommerfe 353:
354: 20020426:
355: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 356:
357: 20020426:
358: etc/postinstall added, which performs various checks for
359: configuration file updates and changes, and can fix most of
360: the problems identified.
361: This should make it much easier to upgrade a system's
362: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 363:
364: 20020320:
1.79 wiz 365: <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.

1.55 itojun 368: 20020319:
1.79 wiz 369: Raw IPv6 socket now makes strict checking for sa_family and sa_len
370: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 371: newer than November 2001 when you upgrade the kernel.
372:
1.54 itojun 373: 20020311:
374: ssh configuration files were moved from /etc to /etc/ssh. Beware
375: if you restart your machine from remote. Note that sshd.conf needs
376: to be changed (due to the use of "/etc" inside).
377:
378: 20020223:
1.53 matt 379: Users of the VAX port will need to rebuild and install gas
380: so it deal with the now present register prefix used in all
381: the VAX assembly files.
382:
1.50 itojun 383: 20020118:
384: ntpd user/group has been added. Need to hand add this in or builds
385: will break as mtree aborts early.
386:
387: Add the following into /etc/group:
388:
389: ntpd:*:15:

1.49 jmc 395: 20011207:
396: If you're attempting to build a snapshot on sparc64 and are getting
397: reloc errors from the toolchain groff binary this means your native
398: toolchain has some broken C++ bits.
399:
400: To fix:
401:
402: Build a new toolchain (i.e. build.sh -t)
403: Use the new toolchain to build and install natively (i.e. /usr/lib)
404:
405: gnu/lib/libgcc
1.51 pooka 406: gnu/lib/libstdc++
1.49 jmc 407:
408: After this a snapshot will be able to be built.
409:
1.47 jmc 410: 20011201:
411: In order for a sparc64 build to work you must have a working awk. If
412: you've built and installed a system with the new toolchain up to this
1.52 wiz 413: point you do not have a working awk as its ability to do floating
1.47 jmc 414: point is broken.
415:
416: To build:
417:
418: remake and install gnu/lib/libgcc
419: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 420: against the new libgcc.a)
1.47 jmc 421:
1.46 thorpej 422: 20011128:
423: Kernel config information was changed to use defflag in
424: the various "files" files. Bug fixes to config(8) are
425: required in order for this to work properly. Make sure
426: to build and install in usr.sbin/config before attempting
427: to build a new kernel.
428:
1.45 yamt 429: 20011030:
430: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
431: before building libc.

1.44 tv 433: 20011029:
434: The new document BUILDING.mdoc (view with nroff | more, or
435: see pre-generated .txt and .html versions) describes the build
436: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
437: build process, are intended in the long run to replace this
438: manual update log.
439:
440: Users building a USE_NEW_TOOLCHAIN system should read the
441: BUILDING document for caveats. Generally, BUILDING supersedes
442: UPDATING for these systems, as tool updating is taken care of
443: by the new build system.
1.42 perry 444:
445: 20011028:
446: src/etc/Makefile now needs install to be able to handle
447: symlinks that point to nowhere. A bug in install that
448: prevented this was corrected.

450: Solution: update and reinstall usr.bin/xinstall
451: Better Solution: Use the new toolchain and it will just work
452: for you.
1.40 lukem 453:

455: /etc/mtree/NetBSD.dist has been updated to take advantage of
456: absolute path support added to mtree(8). Older mtree(8)s don't
457: understand the format.
458:
459: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 460:

463: is suggested before running a snapshot build
1.36 tv 464:
1.35 thorpej 465: 20010915:
466: The new "ubcperf" code committed by Chuck Silvers removed
467: a header file, uvm/uvm_vnode.h. There may be stale .depend
468: files that still reference this file.
469:
470: Solution: "make cleandir && make dependall" in affected
471: directories.
1.31 enami 472:
473: 20010803:
474: grep.info is now built from grep.texi using makeinfo. Since it
475: requires makeinfo v4.0, you need to install new texinfo before
476: building gnu/usr.bin/grep. To install new texinfo, please follow
477: the instruction described in 20010726 entry.
1.30 enami 478:
1.64 sommerfe 479: 20010803:
1.41 wiz 480: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 481: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 482: kernel successfully, you need to build and install a new toolchain,
483: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
484: from your kernel configuration until you rebuild your userland.
485: See 20011029 above and BUILDING file in this directory for more information.
486: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 487:

490: this will be unable to read symbol tables provided by newer
491: bootloaders.
1.27 assar 492:
493: 20010726:
494: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 495: build the included texinfo files, do:
496:
497: cd src/gnu/usr.bin/texinfo
498: make MKINFO=no dependall install
1.25 thorpej 499:
500: 20010718:
501: Enabled correct .init/.fini processing in crt0. The way this
502: was done was to change a -I directive to cc(1), which means
503: make(1) will have a stale dependency (it will be checking the
504: timestamp on the wrong "dot_init.h").
505:
506: The symptom you will see is that new programs die with SIGSEGV
507: if you have a stale dependency.
508:
509: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
510: before starting your build.
1.26 thorpej 511:
512: 20010628:
513: A construct was added to uvm_page.h that uncovered a bug
514: in lint(1). If you get a warning/error about a non-portable
515: bitfield, update your lint(1) before proceeding.
1.21 jmc 516:
517: 20010226:
1.22 jmc 518: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 519: will break as mtree aborts early.
520:
521: To work around add by hand:
522:
523: named:*:14:
524:
1.22 jmc 525: to /etc/group and add:
526:
527: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
528:
529: to master.passwd (use vipw for instance if doing by hand).
530:
531: Now a make build should progress.
1.18 jmc 532:
533: 20010219:
1.52 wiz 534: get/setprogname() added. Any hostprogs that may use this will need
1.111 simonb 535: to be bootstrapped manually until the host system is current.
1.18 jmc 536:
1.111 simonb 537: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 538: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
539: CFLAGS and rebuilding should work)
1.20 jmc 540: usr.sbin/mdsetimage - Build a static copy if
1.111 simonb 541: building a snapshot before fully bootstrapped.
1.15 christos 542:
543: 20010204:
544: prepare the code to compile with stricter gcc flags. in
545: particular start eliminating redundant declarations. Yacc
546: needs to be installed before make build.
1.10 christos 547:
548: 20010114:
549: introduce .if commands(target) in make(1). You need to
550: bring everything up-to-date first, then without installing
1.23 tron 551: anything make and install in usr.bin/make, then proceed
1.10 christos 552: with make build.
1.9 sommerfe 553:
554: 20010101:
555: bsd.subdir.mk committed 20001230 had a bug which caused
556: afterinstall targets to run too soon; update again.
1.8 sommerfe 557:
558: 20001230:
559: New share/mk files needed to support .WAIT in SUBDIR variables.
560: If you get make errors,
561: (cd share/mk; make install)
562: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 563:
564: 20001019:
1.7 ad 565: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 566: major and minor numbers haven't changed, you should update your /dev
567: directory.
1.1 abs 568:
1.4 itojun 569: 20000929:
570: The following make directives are obsoleted.
571: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
572: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 573: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 574: additional library libcrypto_{idea,rc5}.
1.1 abs 575:
576:
577: Hints for a more successful build:
578: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 579: Build a new kernel first:
580: This makes sure that any new system calls or features
581: expected by the new userland will be present. This
582: helps to avoid critical errors when upgrading.
1.1 abs 583: Use object directories:
584: This helps to keep stale object
585: files from polluting the build if a Makefile "forgets"
586: about one. It also makes it easier to clean up after
587: a build. It's also necessary if you want to use the
588: same source tree for multiple machines.
589: To use object directories:
590: a) cd /usr/src ; make cleandir
1.2 mrg 591: b) Add "OBJMACHINE=yes" to /etc/mk.conf
592: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 593: d) cd /usr/src ; make build
1.2 mrg 594: Note that running "make obj" in a directory will create
595: in obj.$MACHINE directory.
1.1 abs 596: Build to a DESTDIR:
597: This helps to keep old
598: installed files (especially libraries) from interfering
599: with the new build.
600: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 601: variable before running make build. It should be set to
602: the pathname of an initially empty directory.
1.1 abs 603: Problems: you might need to update critical utilities
604: without using DESTDIR since nothing is executed
605: from what is installed in DESTDIR.
606: (See critical utils, below)
607: Build often:
608: This keeps critical utilities current enough to not choke
609: on any other part of the source tree that depends on up to
610: date functionality.
611:
612: What to do if things don't work:
613: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
614: When things don't work there is usually a few things that commonly
615: should be done.
616: 1) make includes
617: This should be done automatically by make build.
618: 2) cd share/mk && make install
619: Again, automatically done by make build.
620:
621: Failsafe rebuild of a small part of the tree:
622: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
623: To make sure you rebuild something correctly you want to do
624: something like the following:
625: 1) Make sure the includes and .mk files are up to date.
626: 2) Make sure any program used to build the particular
627: utility is up to date. (yacc, lex, etc...)
628: 3) cd ...path/to/util...
629: make cleandir
630: rm ...all obj directories...
631: make cleandir # yes, again
632: make obj
633: make depend && make
634:
635: Failsafe rebuild of the entire tree:
636: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
637: If you really want to make sure the source tree is clean and
1.2 mrg 638: ready for a build try the following. Note that sourcing /etc/mk.conf
639: (a make(1) Makefile) in this manner is not right, and will not work
640: for anyone who uses any make(1) features in /etc/mk.conf.
