1.114.2.1 tron 11: 20040715:
12: The rc.d/sendmail script now uses a heuristic to determine
13: if sendmail should be started at boot time. It checks the
14: contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
15: owner and mode of the sendmail binary to see if any changes
16: to the mail infrastructure have been made. If no changes
17: are detected, it will start an SMTP listener.
18:
19: Setting sendmail=NO in /etc/rc.conf will override this.
20:
21: If you are only using sendmail by default and only for
22: local delivery, it is important that you also update your
23: sendmail.cf so that the SMTP listener only listens on the
24: loopback interface.
25:
26: 20040715:
27: The method by which athhal-elf.o gets pulled into i386
28: kernel builds has been changed again. The latest version
29: of bsd.files.mk is no longer required.
30:
1.114.2.2! jmc 31: 20040426:
! 32: Support for the original dynamic sysctl node structure has
! 33: been removed in favor of the newer layout. This affects
! 34: consumers of the create and delete interface, as well as
! 35: the dynamic discovery mechanism. This is believed only to
! 36: be the sysctl(8) binary itself, at this point in time, so
! 37: the only effect of this should be that a sysctl binary
! 38: built from sources dated between 2003/12/04 and 2004/03/24
! 39: will not work on a kernel built from sources dated after
! 40: 2004/04/25. If you need a new sysctl binary but build.sh
! 41: does not work, make sure that your revision of
! 42: src/sys/sys/sysctl.h is 1.112 (or later), and then the
! 43: do the following:
! 44:
! 45: cd /usr/src (or wherever your source tree is)
! 46: make USETOOLS=no includes
! 47: cd lib/libc
! 48: make USETOOLS=no dependall install
! 49: cd ../../sbin/sysctl
! 50: make USETOOLS=no dependall install
! 51:
! 52: If you are using older sysctl binary, GNU autoconf would fail to
! 53: identify your machine architecture, and tries to build binary for
! 54: "unknown-unknown-netbsd20F" or something like that. if that happens,
! 55: make sure to follow the above steps.
! 56:
1.114 jmc 57: 20040326:
58:
59: The method by which athhal-elf.o gets pulled into i386 kernel builds
60: has been changed. The file is now stored as a uuencode file in CVS
61: and the generated Makefile will use the new .uue rules from bsd.file.mk
62: to build it.
63:
64: This means you must have the latest bsd.files.mk installed when
65: building a kernel without USETOOLS=yes.
66:
1.113 dan 67: 20040318:
68: A bug in the cgd(4) blowfish code was corrected, without
69: provision of backwards compatibility, after several public
70: notices over several months. Users of cgd with blowfish cipher
71: ONLY must dump their data before updating their kernels, and
72: recreate cgd's and restore data using the new kernel. See
73: (recent message to current-users, URL when mail-index has updated)
74:
1.108 bjh21 75: 20040313:
76: On acorn32, the opms and qms drivers have been withdrawn, and
77: the old wsqms driver is now called qms. Kernel config files
78: will need updating. See the ones in sys/arch/acorn32/conf
79: for examples.
80:
1.106 bjh21 81: 20040125:
82: On acorn32, the beep and sysbeep devices are no longer
83: needed, and will need to be deleted from kernel configuration
84: files.
1.105 bjh21 85:
1.102 dbj 86: 20040109:
87: Compatibility for old ffs superblock layouts has been
88: added, and the restrictive fsck checks have been reenabled
89: when using those layouts. If you have been using -current
90: since 20030402, you may find that fsck again signals fatal
1.110 dbj 91: superblock mismatches. To repair, make sure you have
1.111 simonb 92: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 93: to complete the filesystem upgrade. A message has
1.111 simonb 94: been added to the kernel which should detect this problem.
95: See the following discussion for more information:
1.112 keihan 96: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 97:
1.99 mrg 98: 20031203:
1.100 keihan 99: New binutils builds may fail due to old dependencies.
1.99 mrg 100: It's necessary to "make cleandir" to ensure that
101: the dependencies will be rebuilt correctly.
1.98 wiz 102:
103: 20031111:
104: A newer mkdep is needed. Error noting that is
105: cc: Ambiguous abbreviation --
1.97 lukem 106:
107: 20031008:
108: /usr/include/sys/disklabel_mbr.h was removed.
109: It's necessary to "make cleandir" to ensure that
110: the dependencies will be rebuilt correctly.
1.96 christos 111:
1.109 dbj 112: 20031007:
1.111 simonb 113: A sign exension bug was fixed which set all the high bits
114: of our newly expanded ffs fs_flags. This should only
115: affect users who installed or upgraded in September of 2003.
1.109 dbj 116: A small utility program was posted to tech-kern which
1.111 simonb 117: should fix this problem, and a warning message was added
118: to the kernel which should discover and warn about it. See
119: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 120:
1.96 christos 121: 20030906:
122: With the addition of siginfo support the old signal trampoline
123: code has been deprecated to COMPAT_16. Make sure that your running
124: kernel has COMPAT_16 enabled before building userland.
1.94 christos 125:
126: 20030801:
1.95 wiz 127: With the new openssl, there is some header and library shuffling.
1.94 christos 128: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 129: /usr/lib/libdes* before building.
1.92 wiz 130:
131: 20030703:
132: Texinfo was updated to 4.6. To avoid failures when trying to
133: build the included texinfo files, do:
134:
135: cd src/gnu/usr.bin/texinfo
136: make MKINFO=no dependall install
1.90 wiz 137:
138: 20030630:
1.101 junyoung 139: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 140: cd share/mk && make install
1.90 wiz 141: cd src/gnu/usr.bin/groff
142: make MKMAN=no dependall install
143: (untested).
1.89 christos 144:
145: 20030516:
146: Due to bugs in the export handling code, invalid export lines
147: were accepted before and caused the kernel to panic when
148: mountd got restarted because it freed memory that had already
149: been freed. This has been fixed and the kernel checks
150: export addresses very strictly. If you upgrade your kernel,
151: make sure you also upgrade mountd, because if your export
152: file contains lines with an old inet4 address syntax (i.e.
153: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 154:
155: 20030402:
156: The superblock layout for FFS was changed. If you have 1.6
157: fsck binaries, they will signal a fatal superblock mismatch
158: with the first alternate, because they compare too many
159: fields (even ones that aren't useful). If possible, upgrade
160: your fsck_ffs binary before using a new kernel.
161: None of this signals actual filesystem damage.
1.85 atatat 162:
163: 20030324:
164: sendmail version 8.12.8 was imported. Since sendmail is
165: now setgid to the smmsp group, and runs in "collection"
166: mode for most common activities, there is a new config
167: file called submit.cf that needs to live in /etc/mail.
168: The generic submit.cf sample in /usr/share/sendmail/cf
169: is named netbsd-msp.cf. Upgrading your regular sendmail
170: configuration file is also strongly advised.
171:
172: See the section named "MESSAGE SUBMISSION PROGRAM" in
173: the updated /usr/share/sendmail/README file for more
174: information.
1.82 wiz 175:
176: 20030117:
177: Texinfo was updated to 4.3. To avoid failures when trying to
178: build the included texinfo files, do:
179:
180: cd src/gnu/usr.bin/texinfo
181: make MKINFO=no dependall install
1.81 lukem 182:
183: 20021223:
184: The METALOG format changed slightly, to remove the leading
185: "${DESTDIR}" from path names.
186: This only affects people building with UNPRIVED.
187: For complete safety, remove the DESTDIR entirely and
188: update tools/mtree, before running make build.
1.88 itojun 189:
190: 20021219:
191: CVS repository layout was changed. See the following for details
192: if you are using (anonymous) cvs to update your tree.
193:
1.93 salo 194: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 195:
196: 20021219:
197: install(1) had a '-N dbdir' option added, to specify an
198: alternate location to look up users & groups (instead
199: of the host system passwd(5) and group(5) databases).
200:
201: The build system was modified to take advantage of
202: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 203: use USETOOLS==no, you may have to rebuild and
1.80 lukem 204: reinstall usr.bin/xinstall first.
1.78 lukem 205:
206: 20021130:
207: fparseln(3) moved from libutil to libc.
208: If building to DESTDIR=/, reinstall the includes
209: and rebuild libc:
210: make includes
211: make do-lib-libc
212: If using build.sh, "cd tools/compat && make clean"
213: before rebuilding the tools.
1.77 lukem 214:
215: 20021126:
216: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
217: including the optional "SYS_INCLUDE=symlinks" support.
218: All header files, including <sys/*.h> are copied into
219: /usr/include.
1.76 thorpej 220:
221: 20021121:
222: The C run-time support files crtbegin.o and crtend.o
223: (and their companions crtbeginS.o and crtendS.o) were
224: split up, with new crti.o and crtn.o files resulting.
225: This means that libtool needs to be rebuilt once the
226: new libraries are installed. The process of rebuilding
227: libtool will cause it to automatically notice the new
228: required files, but it *must* be rebuilt in order to
229: do this.
230:
231: An out-of-date libtool will result in shared libraries
232: which lack _init() and _fini() routines, which means that
233: their global contructors/destructors will not be invoked.
1.75 thorpej 234:
235: 20021121:
236: A bug related to how ARM ELF objects were tagged has been
237: corrected.
238:
239: NetBSD ARM ELF uses the soft-VFP floating point model by
240: default. However, the assembler lacked support for marking
241: objects as using the VFP floating point format, and the
1.79 wiz 242: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 243: to the assembler.
244:
245: Unfortunately, this means that the linker will now consider
246: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
247: incompatible with new (properly marked) objects.
248:
249: The problem will only manifest itself if you attempt to compile
250: a new program using the fixed toolchain, and link that program
251: against old libraries which do not have the proper "softvfp"
252: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
253: WILL CONTINUE TO WORK PROPERLY.
254:
255: The only work-around for the problem is to recompile all of
256: the libraries on the system. The easiest way to do this for
1.79 wiz 257: system libraries is to install a binary snapshot; they are
1.93 salo 258: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 259: have installed which supply libraries will have to be recompiled
260: if you wish to link new programs against those libraries.
261:
262: If you have questions about this matter, please contact
1.93 salo 263: port-arm@NetBSD.org.
1.73 provos 264:
265: 20021011:
266: Systrace has been improved to support privilege elevation.
267: Updating the kernel requires the userland part of systrace
1.79 wiz 268: to be rebuilt.
1.72 thorpej 269:
270: 20021010:
271: The config(8) grammar was changed to allow options to register
272: dependencies on attributes, as well as other options. Users
273: must update and reinstall usr.sbin/config before building a new
274: kernel.
1.70 thorpej 275:
276: 20021009:
277: A new attribute dependency syntax was introduced to config(8),
278: which is now used by the SCSI configuration description. Users
1.71 wiz 279: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 280: kernel.
1.69 thorpej 281:
282: 20021003:
283: Several changes have been made to the autoconfiguration
284: framework. Users must update and reinstall usr.sbin/config
285: before building a new kernel.
1.74 jschauma 286:
287: 20021001:
288: The i386mp branch has been merged. To compile a kernel, users
289: will need to add the option 'cpu* at mainbus?' to their configuration
290: file. Multiprocessor kernels will need
291: ioapic* at mainbus? apid ?
292: options MULTIPROCESSOR
293: options COM_MPLOCK
1.68 lukem 294:
295: 20020922:
296: MKDYNAMICROOT=yes enabled by default, which means that
297: certain shared libraries are installed into /lib, the shared
298: linker is installed into /libexec, and all programs in /bin
299: and /sbin are dynamically linked.
300: If you do not use "make build", you should ensure that
301: you have the libraries and shared linker in the new locations,
302: with:
303: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 304:
305: 20020917:
306: USE_NEW_TOOLCHAIN has been replaced with:
307: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
308: there is no working in-tree toolchain (hppa, ns32k, sh5,
309: x86_64).
310: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 311: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 312: enables the cross-build framework even for TOOLCHAIN_MISSING
313: platforms.
1.66 gehenna 314:
315: 20020906:
316: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 317: reinstall usr.sbin/config before building the kernel.
1.65 lukem 318:
319: 20020822:
320: Crunched rescue tools (contents of /bin and /sbin, plus others)
321: are now provided in /rescue.
322:
323: To ensure that these are built statically linked (no matter
324: what the setting of LDSTATIC is), use a crunchgen(1) built
325: from sources newer than 20020820 (see the next entry).
326:
327: 20020820:
328: crunchgen(1) changed to ensure that the generated program
329: is statically linked.
330:
331: Solution: update and reinstall usr.bin/crunch
1.84 grant 332:
333: 20020605:
334: smmsp user/group has been added for sendmail.
335:
336: Add the following into /etc/group:
337:
338: smmsp:*:17:
339:
340: and the following to /etc/master.passwd (via vipw):
341:
342: smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin
1.61 itojun 343:
344: 20020515:
345: sshd user/group has been added. Need to hand add this in, or sshd
346: will not let you log in (with default, or UsePrivlegeSeparation=yes)
347:
348: Add the following into /etc/group:
349:
350: sshd:*:16:

353:
1.63 enami 354: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 355:
1.79 wiz 356: Also /var/chroot/sshd directory needs to be present (digged as part of
357: the build process).
1.60 sommerfe 358:
359: 20020426:
360: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 361:
362: 20020426:
363: etc/postinstall added, which performs various checks for
364: configuration file updates and changes, and can fix most of
365: the problems identified.
366: This should make it much easier to upgrade a system's
367: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 368:
369: 20020320:
1.79 wiz 370: <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.
371: Build and install at usr.bin/xinstall before the build.
1.56 lukem 372:
1.55 itojun 373: 20020319:
1.79 wiz 374: Raw IPv6 socket now makes strict checking for sa_family and sa_len
375: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 376: newer than November 2001 when you upgrade the kernel.
377:
1.54 itojun 378: 20020311:
379: ssh configuration files were moved from /etc to /etc/ssh. Beware
380: if you restart your machine from remote. Note that sshd.conf needs
381: to be changed (due to the use of "/etc" inside).
382:
383: 20020223:
1.53 matt 384: Users of the VAX port will need to rebuild and install gas
385: so it deal with the now present register prefix used in all
386: the VAX assembly files.
387:
1.50 itojun 388: 20020118:
389: ntpd user/group has been added. Need to hand add this in or builds
390: will break as mtree aborts early.
391:
392: Add the following into /etc/group:
393:
394: ntpd:*:15:
395:
396: and the following to /etc/master.passwd (via vipw):
397:

399:
1.49 jmc 400: 20011207:
401: If you're attempting to build a snapshot on sparc64 and are getting
402: reloc errors from the toolchain groff binary this means your native
403: toolchain has some broken C++ bits.
404:
405: To fix:
406:
407: Build a new toolchain (i.e. build.sh -t)
408: Use the new toolchain to build and install natively (i.e. /usr/lib)
409:
410: gnu/lib/libgcc
1.51 pooka 411: gnu/lib/libstdc++
1.49 jmc 412:
413: After this a snapshot will be able to be built.
414:
1.47 jmc 415: 20011201:
416: In order for a sparc64 build to work you must have a working awk. If
417: you've built and installed a system with the new toolchain up to this
1.52 wiz 418: point you do not have a working awk as its ability to do floating
1.47 jmc 419: point is broken.
420:
421: To build:
422:
423: remake and install gnu/lib/libgcc
424: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 425: against the new libgcc.a)
1.47 jmc 426:
1.46 thorpej 427: 20011128:
428: Kernel config information was changed to use defflag in
429: the various "files" files. Bug fixes to config(8) are
430: required in order for this to work properly. Make sure
431: to build and install in usr.sbin/config before attempting
432: to build a new kernel.
433:
1.45 yamt 434: 20011030:
435: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
436: before building libc.
1.43 mason 437:
1.44 tv 438: 20011029:
439: The new document BUILDING.mdoc (view with nroff | more, or
440: see pre-generated .txt and .html versions) describes the build
441: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
442: build process, are intended in the long run to replace this
443: manual update log.
444:
445: Users building a USE_NEW_TOOLCHAIN system should read the
446: BUILDING document for caveats. Generally, BUILDING supersedes
447: UPDATING for these systems, as tool updating is taken care of
448: by the new build system.
1.42 perry 449:
450: 20011028:
451: src/etc/Makefile now needs install to be able to handle
452: symlinks that point to nowhere. A bug in install that
453: prevented this was corrected.
454:
455: Solution: update and reinstall usr.bin/xinstall
456: Better Solution: Use the new toolchain and it will just work
457: for you.
1.40 lukem 458:
459: 20011006:
460: /etc/mtree/NetBSD.dist has been updated to take advantage of
461: absolute path support added to mtree(8). Older mtree(8)s don't
462: understand the format.
463:
464: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 465:

467: Crunchgen has been updated to work via reach-over makefiles. Updating
468: is suggested before running a snapshot build
1.36 tv 469:
1.35 thorpej 470: 20010915:
471: The new "ubcperf" code committed by Chuck Silvers removed
472: a header file, uvm/uvm_vnode.h. There may be stale .depend
473: files that still reference this file.
474:
475: Solution: "make cleandir && make dependall" in affected
476: directories.
1.31 enami 477:
478: 20010803:
479: grep.info is now built from grep.texi using makeinfo. Since it
480: requires makeinfo v4.0, you need to install new texinfo before
481: building gnu/usr.bin/grep. To install new texinfo, please follow
482: the instruction described in 20010726 entry.
1.30 enami 483:
1.64 sommerfe 484: 20010803:
1.41 wiz 485: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 486: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 487: kernel successfully, you need to build and install a new toolchain,
488: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
489: from your kernel configuration until you rebuild your userland.
490: See 20011029 above and BUILDING file in this directory for more information.
491: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 492:
493: 20010731:
494: Bootloader update on ELF platforms. DDB in kernels from before
495: this will be unable to read symbol tables provided by newer
496: bootloaders.
1.27 assar 497:
498: 20010726:
499: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 500: build the included texinfo files, do:
501:
502: cd src/gnu/usr.bin/texinfo
503: make MKINFO=no dependall install
1.25 thorpej 504:
505: 20010718:
506: Enabled correct .init/.fini processing in crt0. The way this
507: was done was to change a -I directive to cc(1), which means
508: make(1) will have a stale dependency (it will be checking the
509: timestamp on the wrong "dot_init.h").
510:
511: The symptom you will see is that new programs die with SIGSEGV
512: if you have a stale dependency.
513:
514: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
515: before starting your build.
1.26 thorpej 516:
517: 20010628:
518: A construct was added to uvm_page.h that uncovered a bug
519: in lint(1). If you get a warning/error about a non-portable
520: bitfield, update your lint(1) before proceeding.
1.21 jmc 521:
522: 20010226:
1.22 jmc 523: Added named user/group to system. Need to hand add this in or builds
1.21 jmc 524: will break as mtree aborts early.
525:
526: To work around add by hand:
527:
528: named:*:14:
529:
1.22 jmc 530: to /etc/group and add:
531:
532: named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
533:
534: to master.passwd (use vipw for instance if doing by hand).
535:
536: Now a make build should progress.
1.18 jmc 537:
538: 20010219:
1.52 wiz 539: get/setprogname() added. Any hostprogs that may use this will need
1.111 simonb 540: to be bootstrapped manually until the host system is current.
1.18 jmc 541:
1.111 simonb 542: Known problems: sys/arch/macppc/stand/fixcoff
1.19 cgd 543: usr.sbin/config (adding -DMAKE_BOOTSTRAP to
544: CFLAGS and rebuilding should work)
1.20 jmc 545: usr.sbin/mdsetimage - Build a static copy if
1.111 simonb 546: building a snapshot before fully bootstrapped.
1.15 christos 547:
548: 20010204:
549: prepare the code to compile with stricter gcc flags. in
550: particular start eliminating redundant declarations. Yacc
551: needs to be installed before make build.
1.10 christos 552:
553: 20010114:
554: introduce .if commands(target) in make(1). You need to
555: bring everything up-to-date first, then without installing
1.23 tron 556: anything make and install in usr.bin/make, then proceed
1.10 christos 557: with make build.
1.9 sommerfe 558:
559: 20010101:
560: bsd.subdir.mk committed 20001230 had a bug which caused
561: afterinstall targets to run too soon; update again.
1.8 sommerfe 562:
563: 20001230:
564: New share/mk files needed to support .WAIT in SUBDIR variables.
565: If you get make errors,
566: (cd share/mk; make install)
567: Also, PRINTOBJDIR has changed and is now used more heavily.
1.6 ad 568:
569: 20001019:
1.7 ad 570: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 571: major and minor numbers haven't changed, you should update your /dev
572: directory.
1.1 abs 573:
1.4 itojun 574: 20000929:
575: The following make directives are obsoleted.
576: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
577: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 578: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 579: additional library libcrypto_{idea,rc5}.
1.1 abs 580:
581:
582: Hints for a more successful build:
583: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 584: Build a new kernel first:
585: This makes sure that any new system calls or features
586: expected by the new userland will be present. This
587: helps to avoid critical errors when upgrading.
1.1 abs 588: Use object directories:
589: This helps to keep stale object
590: files from polluting the build if a Makefile "forgets"
591: about one. It also makes it easier to clean up after
592: a build. It's also necessary if you want to use the
593: same source tree for multiple machines.
594: To use object directories:
595: a) cd /usr/src ; make cleandir
1.2 mrg 596: b) Add "OBJMACHINE=yes" to /etc/mk.conf
597: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 598: d) cd /usr/src ; make build
1.2 mrg 599: Note that running "make obj" in a directory will create
600: in obj.$MACHINE directory.
1.1 abs 601: Build to a DESTDIR:
602: This helps to keep old
603: installed files (especially libraries) from interfering
604: with the new build.
605: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 606: variable before running make build. It should be set to
607: the pathname of an initially empty directory.
1.1 abs 608: Problems: you might need to update critical utilities
609: without using DESTDIR since nothing is executed
610: from what is installed in DESTDIR.
611: (See critical utils, below)
612: Build often:
613: This keeps critical utilities current enough to not choke
614: on any other part of the source tree that depends on up to
615: date functionality.
616:
617: What to do if things don't work:
618: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
619: When things don't work there is usually a few things that commonly
620: should be done.
621: 1) make includes
622: This should be done automatically by make build.
623: 2) cd share/mk && make install
624: Again, automatically done by make build.
625:
626: Failsafe rebuild of a small part of the tree:
627: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
628: To make sure you rebuild something correctly you want to do
629: something like the following:
630: 1) Make sure the includes and .mk files are up to date.
631: 2) Make sure any program used to build the particular
632: utility is up to date. (yacc, lex, etc...)
633: 3) cd ...path/to/util...
634: make cleandir
635: rm ...all obj directories...
636: make cleandir # yes, again
637: make obj
638: make depend && make
639:
640: Failsafe rebuild of the entire tree:
641: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
642: If you really want to make sure the source tree is clean and
1.2 mrg 643: ready for a build try the following. Note that sourcing /etc/mk.conf
644: (a make(1) Makefile) in this manner is not right, and will not work
645: for anyone who uses any make(1) features in /etc/mk.conf.
