Annotation of src/UPDATING, Revision 1.135.2.2
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.

1.135.2.1 tron 18:
1.135.2.2! tron 19: 20050830:
! 20: named.conf was moved from /etc/namedb to /etc.
! 21: postinstall(8) migrates this during interactive use.
! 22: Users of MKUPDATE=yes will need to manually rectify
! 23: this in their DESTDIR.
! 24:
1.135.2.1 tron 25: 20050417:
26: postinstall(8) was moved from /etc to /usr/sbin and made part
27: of the "base" set, to make it easier to invoke after an
28: upgrade.
29:
1.135 jmc 30: 20050211:
31: Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in
32: some of the cross tools to fail if they use configure. Some configure's
33: cache the environment passed in and notice the new environment is
34: different and abort. Doing a clean in tools/ should be enough to
35: make a build continue.
36:
1.134 christos 37: 20050109:
38: Since su is using pam by default now, make sure that you have
39: /etc/pam.d populated (postinstall will do that automatically
40: for you). Otherwise su will fail open (i.e. will not require
41: a password).
42:
1.133 christos 43: 20041229:
44: Make had a path resolution bug that manifested itself as not
45: being able to install openpam.3. This bug has been fixed, but
46: you might need to rebuild make manually first to get through
47: the build.
48:
1.130 christos 49: 20041201:
50: Userland programs have been changed to use /dev/bpf instead of
51: /dev/bpfX. You need to create that device by installing a new
1.131 wiz 52: MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]*
1.99 mrg 53:
1.129 jmc 54: 20041006:
55:
56: A bug was introduced into /bin/sh (var.c rev 1.35) which causes
57: variables to not export correctly to subshells in all cases. This
58: will cause builds to break if that version of /bin/sh is installed
59: on the system. The proper version of /bin/sh can be verified with:
60:
61: ident /bin/sh | grep var
62:
63: Any /bin/sh w. version 1.35 will not work and needs to be updated
64: before attempting a build.
65:
1.127 christos 66: 20041001:
67: The ipfilter kernel sources moved from sys/netinet to
68: dist/sys/ipf/netinet. Due to the move some Makefile
69: dependencies are now dangling requiring a make cleandir
1.128 he 70: before they work again (kdump, ktruss, rescue, ipf, and
71: ftp-proxy are the victims).
1.127 christos 72:
1.125 atatat 73: 20040715:
74: The rc.d/sendmail script now uses a heuristic to determine
75: if sendmail should be started at boot time. It checks the
76: contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
77: owner and mode of the sendmail binary to see if any changes
78: to the mail infrastructure have been made. If no changes
79: are detected, it will start an SMTP listener.
80:
81: Setting sendmail=NO in /etc/rc.conf will override this.
82:
83: If you are only using sendmail by default and only for
84: local delivery, it is important that you also update your
85: sendmail.cf so that the SMTP listener only listens on the
86: loopback interface.
87:
88: 20040715:
89: The method by which athhal-elf.o gets pulled into i386
90: kernel builds has been changed again. The latest version
91: of bsd.files.mk is no longer required.
92:
1.124 jmc 93: 20040621:
94: Due to the recent rototill of tools/compat it's crucial one starts
95: from a clean objdir under tools/*.
96:
97: This is mostly due to generated files (yacc and lex sources) needing
1.125 atatat 98: to be generated with new rules from bsd.hostprog.mk.
1.124 jmc 99:
100: The safest course is to rm -rf all objects under tools before building.
101:
1.121 lukem 102: 20040516:
103: The end-user modifiable X11 configuration has been moved
104: from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
105: Ensure that src and xsrc is up to date, and run
106: "make cleandir" in src/x11 before your next build.
107:
1.126 lukem 108: postinstall currently doesn't migrate the files from
109: /usr/X11R6/lib/X11/* to /etc/X11/* although it does
110: detect that this needs to occur, so you'll have to
111: manually move these files yourself.
112:
1.119 atatat 113: 20040426:
114: Support for the original dynamic sysctl node structure has
115: been removed in favor of the newer layout. This affects
116: consumers of the create and delete interface, as well as
117: the dynamic discovery mechanism. This is believed only to
118: be the sysctl(8) binary itself, at this point in time, so
119: the only effect of this should be that a sysctl binary
120: built from sources dated between 2003/12/04 and 2004/03/24
121: will not work on a kernel built from sources dated after
122: 2004/04/25. If you need a new sysctl binary but build.sh
123: does not work, make sure that your revision of
1.120 atatat 124: src/sys/sys/sysctl.h is 1.112 (or later), and then the
125: do the following:
1.119 atatat 126:
1.120 atatat 127: cd /usr/src (or wherever your source tree is)
128: make USETOOLS=no includes
129: cd lib/libc
130: make USETOOLS=no dependall install
131: cd ../../sbin/sysctl
1.119 atatat 132: make USETOOLS=no dependall install
133:
1.122 itojun 134: If you are using older sysctl binary, GNU autoconf would fail to
135: identify your machine architecture, and tries to build binary for
136: "unknown-unknown-netbsd20F" or something like that. if that happens,
137: make sure to follow the above steps.
138:
1.118 dbj 139: 20040425:
140: The ffs superblock issues listed below under 20040109 and 20030402
141: are now automatically addressed by the /etc/rc.d/fixsb script or by
142: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
143: invocation mentioned below will continue to work and is now
144: automated by those scripts. Note that under certain circumstances,
145: affected filesystems upgraded to a -current kernel first before
146: upgrading their userland with the fixsb and fsck_ffs fixes may
147: encounter a 'freeing free inode' panic when writing to the affected
148: filesystem, so it is a good idea to repair the filesystem as soon as
149: possible. For more details on the fixsb script, see pr install/25138.
150:
1.115 christos 151: 20040418:
1.121 lukem 152: statfs(2) and friends have been replaced with statvfs(2). Before
1.115 christos 153: installing a newly build userland make sure that you are running
154: a newly built kernel with COMPAT_20 set. In addition your libc
155: build might not work (undefined SYS_statfs symbol) because make
156: clean does not know how to remove files it does not know about
1.116 christos 157: anymore. Manually remove all generated .S sources and objects
158: from the libc build directory.
1.115 christos 159:
1.114 jmc 160: 20040326:
161: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 162: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 163: and the generated Makefile will use the new .uue rules from bsd.file.mk
164: to build it.
165:
166: This means you must have the latest bsd.files.mk installed when
167: building a kernel without USETOOLS=yes.
168:
1.113 dan 169: 20040318:
170: A bug in the cgd(4) blowfish code was corrected, without
171: provision of backwards compatibility, after several public
172: notices over several months. Users of cgd with blowfish cipher
173: ONLY must dump their data before updating their kernels, and
174: recreate cgd's and restore data using the new kernel. See
175: (recent message to current-users, URL when mail-index has updated)
176:
1.108 bjh21 177: 20040313:
178: On acorn32, the opms and qms drivers have been withdrawn, and
179: the old wsqms driver is now called qms. Kernel config files
180: will need updating. See the ones in sys/arch/acorn32/conf
181: for examples.
182:
1.106 bjh21 183: 20040125:
184: On acorn32, the beep and sysbeep devices are no longer
185: needed, and will need to be deleted from kernel configuration
186: files.
1.105 bjh21 187:
1.102 dbj 188: 20040109:
189: Compatibility for old ffs superblock layouts has been
190: added, and the restrictive fsck checks have been reenabled
191: when using those layouts. If you have been using -current
192: since 20030402, you may find that fsck again signals fatal
1.110 dbj 193: superblock mismatches. To repair, make sure you have
1.111 simonb 194: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 195: to complete the filesystem upgrade. A message has
1.111 simonb 196: been added to the kernel which should detect this problem.
197: See the following discussion for more information:
1.112 keihan 198: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 199:
1.99 mrg 200: 20031203:
1.100 keihan 201: New binutils builds may fail due to old dependencies.
1.99 mrg 202: It's necessary to "make cleandir" to ensure that
203: the dependencies will be rebuilt correctly.
1.98 wiz 204:
205: 20031111:
206: A newer mkdep is needed. Error noting that is
207: cc: Ambiguous abbreviation --
1.97 lukem 208:
209: 20031008:
210: /usr/include/sys/disklabel_mbr.h was removed.
211: It's necessary to "make cleandir" to ensure that
212: the dependencies will be rebuilt correctly.
1.96 christos 213:
1.109 dbj 214: 20031007:
1.111 simonb 215: A sign exension bug was fixed which set all the high bits
216: of our newly expanded ffs fs_flags. This should only
217: affect users who installed or upgraded in September of 2003.
1.109 dbj 218: A small utility program was posted to tech-kern which
1.111 simonb 219: should fix this problem, and a warning message was added
220: to the kernel which should discover and warn about it. See
221: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 222:
1.96 christos 223: 20030906:
224: With the addition of siginfo support the old signal trampoline
225: code has been deprecated to COMPAT_16. Make sure that your running
226: kernel has COMPAT_16 enabled before building userland.
1.94 christos 227:
228: 20030801:
1.95 wiz 229: With the new openssl, there is some header and library shuffling.
1.94 christos 230: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 231: /usr/lib/libdes* before building.
1.92 wiz 232:
233: 20030703:
234: Texinfo was updated to 4.6. To avoid failures when trying to
235: build the included texinfo files, do:
236:
237: cd src/gnu/usr.bin/texinfo
238: make MKINFO=no dependall install
1.90 wiz 239:
240: 20030630:
1.101 junyoung 241: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 242: cd share/mk && make install
1.90 wiz 243: cd src/gnu/usr.bin/groff
244: make MKMAN=no dependall install
245: (untested).
1.89 christos 246:
247: 20030516:
248: Due to bugs in the export handling code, invalid export lines
249: were accepted before and caused the kernel to panic when
250: mountd got restarted because it freed memory that had already
251: been freed. This has been fixed and the kernel checks
252: export addresses very strictly. If you upgrade your kernel,
253: make sure you also upgrade mountd, because if your export
254: file contains lines with an old inet4 address syntax (i.e.
255: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 256:
257: 20030402:
258: The superblock layout for FFS was changed. If you have 1.6
259: fsck binaries, they will signal a fatal superblock mismatch
260: with the first alternate, because they compare too many
261: fields (even ones that aren't useful). If possible, upgrade
262: your fsck_ffs binary before using a new kernel.
263: None of this signals actual filesystem damage.
1.85 atatat 264:
265: 20030324:
266: sendmail version 8.12.8 was imported. Since sendmail is
267: now setgid to the smmsp group, and runs in "collection"
268: mode for most common activities, there is a new config
269: file called submit.cf that needs to live in /etc/mail.
270: The generic submit.cf sample in /usr/share/sendmail/cf
271: is named netbsd-msp.cf. Upgrading your regular sendmail
272: configuration file is also strongly advised.
273:
274: See the section named "MESSAGE SUBMISSION PROGRAM" in
275: the updated /usr/share/sendmail/README file for more
276: information.
1.82 wiz 277:
278: 20030117:
279: Texinfo was updated to 4.3. To avoid failures when trying to
280: build the included texinfo files, do:
281:
282: cd src/gnu/usr.bin/texinfo
283: make MKINFO=no dependall install
1.81 lukem 284:
285: 20021223:
286: The METALOG format changed slightly, to remove the leading
287: "${DESTDIR}" from path names.
288: This only affects people building with UNPRIVED.
289: For complete safety, remove the DESTDIR entirely and
290: update tools/mtree, before running make build.
1.88 itojun 291:
292: 20021219:
293: CVS repository layout was changed. See the following for details
294: if you are using (anonymous) cvs to update your tree.
295:
1.93 salo 296: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 297:
298: 20021219:
299: install(1) had a '-N dbdir' option added, to specify an
300: alternate location to look up users & groups (instead
301: of the host system passwd(5) and group(5) databases).
302:
303: The build system was modified to take advantage of
304: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 305: use USETOOLS==no, you may have to rebuild and
1.80 lukem 306: reinstall usr.bin/xinstall first.
1.78 lukem 307:
308: 20021130:
309: fparseln(3) moved from libutil to libc.
310: If building to DESTDIR=/, reinstall the includes
311: and rebuild libc:
312: make includes
313: make do-lib-libc
314: If using build.sh, "cd tools/compat && make clean"
315: before rebuilding the tools.
1.77 lukem 316:
317: 20021126:
318: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
319: including the optional "SYS_INCLUDE=symlinks" support.
320: All header files, including <sys/*.h> are copied into
321: /usr/include.
1.76 thorpej 322:
323: 20021121:
324: The C run-time support files crtbegin.o and crtend.o
325: (and their companions crtbeginS.o and crtendS.o) were
326: split up, with new crti.o and crtn.o files resulting.
327: This means that libtool needs to be rebuilt once the
328: new libraries are installed. The process of rebuilding
329: libtool will cause it to automatically notice the new
330: required files, but it *must* be rebuilt in order to
331: do this.
332:
333: An out-of-date libtool will result in shared libraries
334: which lack _init() and _fini() routines, which means that
335: their global contructors/destructors will not be invoked.
1.75 thorpej 336:
337: 20021121:
338: A bug related to how ARM ELF objects were tagged has been
339: corrected.
340:
341: NetBSD ARM ELF uses the soft-VFP floating point model by
342: default. However, the assembler lacked support for marking
343: objects as using the VFP floating point format, and the
1.79 wiz 344: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 345: to the assembler.
346:
347: Unfortunately, this means that the linker will now consider
348: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
349: incompatible with new (properly marked) objects.
350:
351: The problem will only manifest itself if you attempt to compile
352: a new program using the fixed toolchain, and link that program
353: against old libraries which do not have the proper "softvfp"
354: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
355: WILL CONTINUE TO WORK PROPERLY.
356:
357: The only work-around for the problem is to recompile all of
358: the libraries on the system. The easiest way to do this for
1.79 wiz 359: system libraries is to install a binary snapshot; they are
1.93 salo 360: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 361: have installed which supply libraries will have to be recompiled
362: if you wish to link new programs against those libraries.
363:
364: If you have questions about this matter, please contact
1.93 salo 365: port-arm@NetBSD.org.
1.73 provos 366:
367: 20021011:
368: Systrace has been improved to support privilege elevation.
369: Updating the kernel requires the userland part of systrace
1.79 wiz 370: to be rebuilt.
1.72 thorpej 371:
372: 20021010:
373: The config(8) grammar was changed to allow options to register
374: dependencies on attributes, as well as other options. Users
375: must update and reinstall usr.sbin/config before building a new
376: kernel.
1.70 thorpej 377:
378: 20021009:
379: A new attribute dependency syntax was introduced to config(8),
380: which is now used by the SCSI configuration description. Users
1.71 wiz 381: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 382: kernel.
1.69 thorpej 383:
384: 20021003:
385: Several changes have been made to the autoconfiguration
386: framework. Users must update and reinstall usr.sbin/config
387: before building a new kernel.
1.74 jschauma 388:
389: 20021001:
390: The i386mp branch has been merged. To compile a kernel, users
391: will need to add the option 'cpu* at mainbus?' to their configuration
392: file. Multiprocessor kernels will need
393: ioapic* at mainbus? apid ?
394: options MULTIPROCESSOR
395: options COM_MPLOCK
1.68 lukem 396:
397: 20020922:
398: MKDYNAMICROOT=yes enabled by default, which means that
399: certain shared libraries are installed into /lib, the shared
400: linker is installed into /libexec, and all programs in /bin
401: and /sbin are dynamically linked.
402: If you do not use "make build", you should ensure that
403: you have the libraries and shared linker in the new locations,
404: with:
405: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so

408: USE_NEW_TOOLCHAIN has been replaced with:
409: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
410: there is no working in-tree toolchain (hppa, ns32k, sh5,
411: x86_64).
412: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 413: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 414: enables the cross-build framework even for TOOLCHAIN_MISSING
415: platforms.
1.66 gehenna 416:

422: Crunched rescue tools (contents of /bin and /sbin, plus others)
423: are now provided in /rescue.
424:
425: To ensure that these are built statically linked (no matter
426: what the setting of LDSTATIC is), use a crunchgen(1) built
427: from sources newer than 20020820 (see the next entry).
428:

503: If you're attempting to build a snapshot on sparc64 and are getting
504: reloc errors from the toolchain groff binary this means your native
505: toolchain has some broken C++ bits.
506:
507: To fix:
508:
509: Build a new toolchain (i.e. build.sh -t)
510: Use the new toolchain to build and install natively (i.e. /usr/lib)
511:
512: gnu/lib/libgcc

1.47 jmc 521: point is broken.
522:
523: To build:

541: The new document BUILDING.mdoc (view with nroff | more, or
542: see pre-generated .txt and .html versions) describes the build
543: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
544: build process, are intended in the long run to replace this
545: manual update log.
546:
547: Users building a USE_NEW_TOOLCHAIN system should read the
548: BUILDING document for caveats. Generally, BUILDING supersedes
549: UPDATING for these systems, as tool updating is taken care of
550: by the new build system.

580: 20010803:
581: grep.info is now built from grep.texi using makeinfo. Since it
582: requires makeinfo v4.0, you need to install new texinfo before

1.30 enami 585:
1.64 sommerfe 586: 20010803:
1.41 wiz 587: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 588: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 589: kernel successfully, you need to build and install a new toolchain,
590: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
591: from your kernel configuration until you rebuild your userland.
592: See 20011029 above and BUILDING file in this directory for more information.
593: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]

608: Enabled correct .init/.fini processing in crt0. The way this
609: was done was to change a -I directive to cc(1), which means
610: make(1) will have a stale dependency (it will be checking the
611: timestamp on the wrong "dot_init.h").
612:
613: The symptom you will see is that new programs die with SIGSEGV
614: if you have a stale dependency.
615:
616: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
617: before starting your build.
1.26 thorpej 618:
619: 20010628:

622: bitfield, update your lint(1) before proceeding.
1.21 jmc 623:

653: needs to be installed before make build.
1.10 christos 654:
655: 20010114:
656: introduce .if commands(target) in make(1). You need to
657: bring everything up-to-date first, then without installing
1.23 tron 658: anything make and install in usr.bin/make, then proceed
1.10 christos 659: with make build.
1.9 sommerfe 660:

1.8 sommerfe 664:
665: 20001230:
666: New share/mk files needed to support .WAIT in SUBDIR variables.
667: If you get make errors,
668: (cd share/mk; make install)
669: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 670:
671: 20001019:
1.7 ad 672: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 673: major and minor numbers haven't changed, you should update your /dev
674: directory.
1.1 abs 675:

677: The following make directives are obsoleted.
678: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
679: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 680: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 681: additional library libcrypto_{idea,rc5}.
1.1 abs 682:
683:
684: Hints for a more successful build:
685: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 686: Use build.sh, but do not use its "expert mode":
1.132 jmmv 687: This will automatically build the tools in the
1.123 jmc 688: correct order, and it will keep the tools and the
689: new build products from interfering with the running
690: system. This will allow you to ignore most of the
691: other advice in this file.
1.2 mrg 692: Build a new kernel first:
693: This makes sure that any new system calls or features
694: expected by the new userland will be present. This
695: helps to avoid critical errors when upgrading.
1.1 abs 696: Use object directories:
697: This helps to keep stale object
698: files from polluting the build if a Makefile "forgets"
699: about one. It also makes it easier to clean up after
700: a build. It's also necessary if you want to use the
701: same source tree for multiple machines.
1.123 jmc 702: To use object directories with build.sh:
703: a) invoke build.sh with the "-M" or "-O" options.
704: To use object directories without using build.sh:
1.1 abs 705: a) cd /usr/src ; make cleandir
1.2 mrg 706: b) Add "OBJMACHINE=yes" to /etc/mk.conf
707: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 708: d) cd /usr/src ; make build
1.2 mrg 709: Note that running "make obj" in a directory will create
710: in obj.$MACHINE directory.
1.1 abs 711: Build to a DESTDIR:
1.123 jmc 712: This helps to keep old installed files (especially libraries)
713: from interfering with the new build.
714: To build to a DESTDIR with build.sh, use the "-D" option.
715: To build to a DESTDIR without using build.sh, set the DESTDIR
716: environment variable before running make build. It should be
717: set to the pathname of an initially empty directory.
718: Problems: if you do not use build.sh, you might need to
719: update critical utilities without using DESTDIR since
720: nothing is executed from what is installed in DESTDIR.
721: (See critical utils, below.)
1.1 abs 722: Build often:
723: This keeps critical utilities current enough to not choke
724: on any other part of the source tree that depends on up to
1.123 jmc 725: date functionality. If you use build.sh, you should not have
726: this problem.
1.1 abs 727:
728: What to do if things don't work:
729: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
730: When things don't work there is usually a few things that commonly
731: should be done.
732: 1) make includes
733: This should be done automatically by make build.
734: 2) cd share/mk && make install
735: Again, automatically done by make build.
736:
737: Failsafe rebuild of a small part of the tree:
738: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
739: To make sure you rebuild something correctly you want to do
740: something like the following:
741: 1) Make sure the includes and .mk files are up to date.
742: 2) Make sure any program used to build the particular
743: utility is up to date. (yacc, lex, etc...)
744: 3) cd ...path/to/util...
745: make cleandir
746: rm ...all obj directories...
747: make cleandir # yes, again
748: make obj
749: make depend && make
750:
751: Failsafe rebuild of the entire tree:
752: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
753: If you really want to make sure the source tree is clean and
1.2 mrg 754: ready for a build try the following. Note that sourcing /etc/mk.conf
755: (a make(1) Makefile) in this manner is not right, and will not work
756: for anyone who uses any make(1) features in /etc/mk.conf.
