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.
13:
1.257 apb 14: Sections are marked with "^^^^^". After the section on "Recent changes"
15: are several sections containing more general information.

1.230 tls 21:
1.273 ! mrg 22: 20160914:
! 23: i386, amd64, shark, ofppc and macppc have joined shark and x68k
! 24: ports in using xorg-server 1.18. This requires a clean destdir
! 25: and a clean objdir.
! 26:
1.272 dholland 27: 20160527:
28: i386 needs a full cleandir or objdir deletion because PIE has
29: been enabled. (see the amd64 entry two down for further info)
30:
1.270 christos 31: 20160418:
32: libedit needs manual removal of all autogenerated files since
1.271 christos 33: some of them are not autogenerated anymore. Remember that there
34: might be two copies of libedit if your platform builds "compat".
1.270 christos 35:
1.268 riastrad 36: 20160410:
37: amd64 needs full "make cleandir" or deletion of objdir now that
38: PIE has been enabled for amd64. PIE, or position-independent
39: executables, means all code, including executables and not just
40: shared libraries, is position-independent and hence able to be
41: relocated by ASLR, address space layout randomization.
42:
43: The change was made in Makefile variables for compiler and
44: linker flags, for which make(1) does not record dependencies,
45: hence it is unable to detect that all .o files need rebuilding.
46:
47: Partial rebuilds with some modified source files will likely
48: fail when linking executables, since the linker refuses to mix
49: position-independent code with position-dependent code in
50: position-independent executables:
51:
52: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
53:
1.267 mrg 54: 20160401:
55: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 56: Some people have found that cleandir is not sufficient, so if
57: in doubt delete the entire object directory tree for gcc.
1.267 mrg 58:
1.266 aymeric 59: 20160306:
1.265 aymeric 60: NetBSD's regexp implementation is now part of libnbcompat.
61: Nblex, nbm4, nbpax, nbsed use it and they may crash on
62: non-NetBSD hosts if linked with stale object files produced
63: while they included a non-NetBSD regex.h.
64: In any case, you should "make cleandir" at least these tools
65: before updating your toolchain.
66:
1.264 martin 67: 20160125:
68: Dtrace has been enabled by default on some architectures.
69: When doing an update build, make sure to clean the etc/mtree
70: object directory before starting the build - otherwise the
71: needed directories in destdir will not be created.
72: An easy way to do this is:
73: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
74:
1.263 dholland 75: 20150818:
76: New acpica requires "make cleandir" in src/external/bsd/acpica
77: again.
78:
1.262 christos 79: 20150413:
80: New acpica requires "make cleandir" and reinstalling yacc
81: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
82: also "make cleandir" in /usr/src/external/bsd/acpica.
83:
1.261 martin 84: 20150404:
85: Lint changes require a full rebuild of the tool, so make
86: sure to build without -u option to build.sh, or manually
87: do a make cleandir in src/tools/lint1 and
88: src/usr.bin/xlint.
89:
1.260 skrll 90: 20150310:
91: Improvements to openssl for arm mean that update builds of
92: the openssl libraries will fail. A make cleandir in
93: external/bsd/openssl/lib is needed
94:
1.258 martin 95: 20141026:
1.259 msaitoh 96: A mishap during the import of pppd may cause your corruption
1.258 martin 97: in your cvs directory if you happened to do a cvs update
98: during a short period of time. To fix, just remove the
99: directory src/external/bsd/ppp/dist/pppd completely
100: and let cvs restore it on next update.
101:
1.256 apb 102: 20140721:
103: The src/external/mit/lua/src directory was accidentally created
104: and then deleted in the CVS repository. If you get errors like
105:
106: cvs [update aborted]: cannot open directory
107: /cvsroot/src/external/mit/lua/src: No such file or directory
108:
109: then delete your local copy of that directory tree and try again.
110:
1.255 joerg 111: 20140530:
112: ARM eABI switched to DWARF based exception handling. This requires
113: rebuilding all C++ code. It is strongly advised to do a clean build.
114:
1.251 martin 115: 20140131:
1.253 joerg 116: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 117: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 118: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 119:
1.250 christos 120: 20131227:
121: 1. The new ntpd runs in a restricted mode to prevent amplification
122: attacks. If you need ntpdc to work you need to explicitly enable
123: mode7 in your config file. Make sure you put the necessary restrict
124: statements to avoid being exposed.
125: 2. strncat has moved from lib/libc to common/lib/libc; you might need
126: to make clean in libc
127:
1.249 mrg 128: 20131129:
129: The GMP sources were updated, and builds will likely fail without
130: cleaning their build trees for both tools and in-tree, like below.
131:
1.248 mrg 132: 20131128:
133: The MPC and MPFR sources were updated, and builds may require their
134: tools and in-tree directories cleaned for successful updates.
135:
1.246 martin 136: 20130605:
1.247 spz 137: The kernel option FAST_IPSEC no longer exists, it's been renamed
138: to IPSEC (and the older IPSEC version removed).
139:
140: 20130605:
1.246 martin 141: Previous freetype installations eroneously installed private
142: header files. If you are building against a non-empty $DESTDIR,
143: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
144:
1.245 mrg 145: 20130531:
146: The xdm update may cause build failure due to xdm.man being
147: in the obj tree. Make sure to ensure any like this:
148: nbmake: nbmake: don't know how to make xdm.man. Stop
149: is fixed by deleting the xdm.man in the obj tree.
150:
1.244 mrg 151: 20130530:
152: Updates of many xsrc packages will leave old .pc files around.
153: Best to clean out the xsrc objdir entirely before rebuilds.
154:
1.242 christos 155: 20130301:
156: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 157: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 158:
1.238 dholland 159: 20120726:
1.241 wiz 160: The update of OpenSSL requires cleaning both the OpenSSL build
161: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 162: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 163: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 164: cause third-party software to link incorrectly and/or crash.
1.238 dholland 165:
1.237 wiz 166: 20120507:
1.241 wiz 167: The database schema for makemandb was changed. You will
1.237 wiz 168: need to update the database using 'makemandb -f' or wait
169: for the next weekly run to fix it.
170:
1.236 bsh 171: 20120319:
172: sys/conf/Makefile.kern.inc has been modified to adjust the
173: size of db_symtab automatically. You need to update dbsym in
174: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
175: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
176: mk.conf.
177:
1.235 joerg 178: 20120216:
1.241 wiz 179: Default for MKCATPAGES changed to NO. Update builds will fail
180: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 181: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 182: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 183: the next run of weekly will fix it.
1.233 joerg 184:
1.232 christos 185: 20111227:
186: If you built between 20111225 and 20111227 you need to remove
187: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
188: bump has been reverted.
189:
1.231 tls 190: 20111125:
191: The "rnd" pseudodevice has been added to sys/conf/std, which
192: means it should no longer be explicitly listed in kernel
193: configuration files. The line "pseudo-device rnd" should be
194: removed from any custom kernel config files users may have.
195:
1.230 tls 196: 20111119:
197: A problem with the datastructures used by the rndctl(8)
198: utility (pointers in datastructures in an array, making 32->64
199: bit compatibility very painful) has been fixed in a
200: non-backwards-compatible way. If you replace your kernel,
201: replace your rndctl executable too.
1.241 wiz 202:
1.229 jym 203: 20111001:
204: the prop_*_send_syscall() functions from proplib(3) have been
205: changed and their new version is not backward compatible with the old
1.241 wiz 206: one. So ensure that all consumers of these functions (currently:
1.229 jym 207: quota2 code and its tests) are updated together with the new lib.
208:
1.228 mrg 209: 20110817:
210: sparc has been changed to use GCC 4.5.3, so any objdir or
211: DESTDIR for them should be deleted before updating.
212:
1.227 riastrad 213: 20110806:
214: i386 and amd64 have been changed to use GCC 4.5.3, so any
215: objdir or DESTDIR for them should be deleted before updating.
216:
1.226 mrg 217: 20110805:
218: The update to GCC 4.5.3 requires a non-trivial portion of
219: the tree to be cleaned. Best to delete both objdir and
220: DESTDIR before running this update. So far, only the
221: sparc64, mips and powerpc platforms have changed.
222:
1.225 matt 223: 20110803:
1.241 wiz 224: The layout of external/public-domain/xz has changed. To do an
1.225 matt 225: update build you will have to remove the contents of the OBJDIR
226: for external/public-domain/xz/bin by hand as the xz entry there
227: is now a directory.
228:
1.223 joerg 229: 20110410:
1.241 wiz 230: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 231: update build you have to clean both tools/binutils and
232: tools/gcc by hand.
1.223 joerg 233:
1.222 plunky 234: 20110328:
235: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 236: ordering issues with "make all". It may be necessary to remove
1.222 plunky 237: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
238: if your update build fails, as the "Xorg" entry there is now a
239: directory.
240:
1.220 joerg 241: 20110121:
1.221 lukem 242: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 243: the build of individual parts of the tree. This is handled
244: correctly by build.sh. Manual builds have to update /usr/share/mk
245: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 246:
1.217 jruoho 247: 20101217:
248: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 249: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 250: group(5) in order to make the program work with existing setups.
251:
1.216 christos 252: 20101125:
253: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 254: variables with names that contain '='. Revision 1.18 of env.c
255: assumed that this was allowed. Installing a new libc with an
1.216 christos 256: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
257: break which affects the autoconf tests for dependency finding,
258: so building gcc will end up printing:
259: checking dependency style of gcc... none
260: configure: error: no usable dependency style found
261: Fix it by rebuilding and re-installing env.
1.138 lukem 262:
1.215 mrg 263: 20101119:
264: Recent Xorg updates in xsrc/external/mit/ may cause various build
265: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
266: have any build problems with xsrc, or problems with mismatched
267: versions between xorg-server and drivers.
268:
1.213 jmmv 269: 20100604:
270: The update of ATF to 0.9 causes old tests written in shell to fail
271: unless they are rebuilt. If you are building with MKUPDATE=yes,
272: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
273: trees by hand.
274:
1.211 tnozaki 275: 20100522:
1.212 mrg 276: Recent Xorg updates in xsrc/external/mit/ will cause various build
277: problems. Delete your entire DESTDIR and OBJDIR if you have any
278: build problems with xsrc.
279:
280: 20100522:
1.211 tnozaki 281: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 282: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 283:
1.210 christos 284: 20100520:
1.241 wiz 285: The location of the xkb compiled descriptions has changed. Please
1.210 christos 286: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
287:
1.209 njoly 288: 20100222:
289: The shared objects file extension has been changed from .so to
290: .pico, in order to avoid conflicts with shared libraries names
291: libXX.so. All now stale regular .so files can be removed from
292: your object directories.
293:
1.208 roy 294: 20100204:
295: The termcap database has been removed from the sources,
296: but has not been marked obsolete so it is not removed
297: from the system when upgrading.
298: As such, you will need to remove them from your object
299: and destination directories.
300:
1.203 dyoung 301: 20091101:
1.205 dholland 302: After updating, it may be necessary to make the 'cleandir'
303: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
304: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
305: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 306:
1.202 mrg 307: 20091001:
1.206 dholland 308: On amd64 you must rebuild tools (to get the new binutils)
309: before building a kernel, or the build fails on cpufunc.S.
310:
311: 20091001:
1.202 mrg 312: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
313: symlink, failing the build. Delete the link, and the subdir
314: it is in, and retry your build.
315:
1.201 dsl 316: 20090718:
317: libc build changed so that strchr() provides the extra entry
1.241 wiz 318: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 319: may fail because the archive contains the unwanted index.o.
320: (Similarly for strrchr() and rindex().)
321:
1.198 mrg 322: 20090709:
323: Native Xorg was upgraded again. Builds will probably fail again
324: without a clean objdir, at least for src/external/mit/xorg.
325:
1.197 mrg 326: 20090616:
327: Native Xorg was upgraded. Builds will need a clean objdir for
328: src/external/mit/xorg. Upgrading a system from sets will not
329: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
330: subdirectory has been changed into a file, and this needs to
331: be manually "rm -r"'ed before installing xbase.tgz.
332:
1.195 perry 333: 20090501:
334: Several new functions were added to string.h/libc, and this
335: can cause autoconf problems during the tool build for people
1.241 wiz 336: who fail to clean out their tools objects properly. If you
1.195 perry 337: note messages about stpcpy, stpncpy or strnlen accompanying a
338: failure during the tool build, clean out all your tools
339: objects and start again.
340:
1.194 mrg 341: 20090325:
342: The i386 port was switched to i486 default toolchain. This requires
343: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
344:
1.192 skrll 345: 20090126:
1.241 wiz 346: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 347: need to 'rm -f __posix_fadvise50.*' in the libc build directory
348: to avoid using the old assembly stub.
1.192 skrll 349:
1.191 joerg 350: 20090202:
351: pkg_install now depends on the pkgdb cache for automatic conflict
352: detection. It is recommented to rebuild the cache with
353: ``pkg_admin rebuild''.
354:
1.184 christos 355: 20090110:
1.241 wiz 356: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
357: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 358: This is needed even in the MODULAR kernel because there is
359: conditionally compiled code in rtsock.c.
1.184 christos 360: 2. make sure build.sh completes and the binaries in a chroot work
361: before installing.
362: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 363: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 364: are installed properly, and start building libraries first libc
365: and libutil, install them and then continue building all the
1.241 wiz 366: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 367: the new libraries are installed, you can restart the build.
368: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 369: rebuild the required packages to update their shared libraries.
370: Any package you rebuild will require rebuilding all the packages
371: that depend on it.
1.186 christos 372: 5. Next time you run pwd_mkdb with the new binary, the file
373: will be upgraded and it will not be backwards compatible.
1.190 apb 374: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
375: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 376: for utmp. You are better off removing the old files after
1.190 apb 377: upgrading. The automated clearing of /var/run during
378: boot, and the automated rotating of files in /var/log by
379: newsyslog(8), may mean that you do not have to remove the
380: files manually.
381: 7. The optional accounting file (/var/account/acct, see
382: accton(8)) has not been versioned, and will need to be
383: removed. The automatic rotation of the accounting file by
384: /etc/daily limits the bad consequences of failure to remove
385: the file.
1.196 dholland 386: 8. Application software that writes time_t to binary files on
1.241 wiz 387: disk will break or need attention. Most notably: if you are
1.196 dholland 388: using PostgreSQL < 8.4, you need to dump your databases,
389: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 390:
1.183 pgoyette 391: 20081219:
392: config(1) has been updated, and one of the files it creates -
393: swapnetbsd.o - has changed format. You need to rebuild config
394: (done automatically by build.sh) and then you need to rerun
395: config on all kernel configuration files before rebuilding those
396: kernels.
397:
1.181 cube 398: 20081205:
399: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
400: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc

1.182 tsutsui 404: On i386, various kernel options(4) in GENERIC including
1.180 wiz 405: file systems have been disabled and moved into kernel modules.
406: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 407: following files as well as a new GENERIC kernel:
408:
409: - build and install kernel modules from src/sys/modules
410:
411: - install the latest bootloader, which will load a module
1.180 wiz 412: for the file system from which the kernel is loaded automatically
1.179 tsutsui 413:
1.180 wiz 414: If you have to load your kernel from a file system which is not of
415: the same type as the root file system, you have to load the necessary
416: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 417:

419: If you built and installed a libc from sources between
420: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
421: which results in false errors reported by lint(1).
422: Since this breaks the libc build itself, manual help is
1.180 wiz 423: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 424: $ (cd lib/libc && make MKLINT=no dependall install)

431: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 432: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 433: for -current.
434:
435: Threaded programs (using libpthread) and C++ programs (using
436: libstdc++) compiled after 20070907 and before 20080802 need to
437: be recompiled.
438:

445: WAPBL (metadata journaling support) has been added, but at this
446: time isn't backwards compatible with pre-WAPBL aware kernels
447: and userland (fsck_ffs in particular). Please make sure you
448: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 449: especially an uncleanly mounted journaled filesystem. WAPBL

1.168 joerg 493:
1.166 xtraeme 494: 20071115:
495: The it(4) driver has been renamed to itesio(4) and the old port
496: argument specified in the kernel configuration file is not valid
1.241 wiz 497: anymore. The itesio(4) driver now uses the Super I/O address port

1.166 xtraeme 500:
1.165 jmmv 501: 20071028:
502: The pccons(4) driver has been removed from the NetBSD/shark port.
503: You need to update any custom kernel configuration file you have
504: to remove any references to pccons (which includes removing the
505: now useless XSERVER option) and replace them with the correct

1.164 gdt 509: 20070913:
510: A latent bug in dhclient/dhcpd that caused it to be unable to
511: enumerate interfaces was fixed. The bug began to cause
512: problems after 20070911 when the kernel's SIOCGIFCONF
513: implementation was repaired. From 20070529 to 20070911 racoon
514: could not enumerate interfaces. (These are noted because
515: normal kernel/userspace version matching hygiene is not
516: sufficient to avoid this problem.) Ensure that both kernel
517: and userland are from after 20070913.
518:

1.241 wiz 520: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
1.199 dholland 521: calls the target-specific strip program, and the logic to pass
522: down STRIP from make has been removed. This requires a
523: re-installation of tools.
1.163 joerg 524:
1.161 dsl 525: 20070422:
526: The way OS emulations lookup filenames inside the emulation root
527: has been changed. Rather than modify the pathname (and copy back
528: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 529: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 530: root file system will be relative to that file system - unless they
1.161 dsl 531: start /../ this is useful when the emulated root is a real install
532: that has such links.
533: This might affect symlinks that have been added to reference outside

544: updated and built after about 20070315, do "nbmake-$arch
545: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a

1.157 apb 556: 20070209:
557: The threading model was changed when the newlock2 branch
558: was merged to NetBSD-current. If you boot with a new
559: kernel (version 4.99.10), then you also need a new pthread
560: library (/usr/lib/libpthread.so.0.7). If you boot with
561: an old kernel, then you need the old pthread library
562: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
563: the pthread library in sync, old threaded applications should
564: continue to work with an old or new kernel. Note that named(8)
565: is the only threaded application in the base system.

1.1 abs 605: Hints for a more successful build:
606: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 607: Use build.sh, but do not use its "expert mode":
1.132 jmmv 608: This will automatically build the tools in the
1.123 jmc 609: correct order, and it will keep the tools and the
610: new build products from interfering with the running
611: system. This will allow you to ignore most of the
612: other advice in this file.
1.2 mrg 613: Build a new kernel first:
614: This makes sure that any new system calls or features
615: expected by the new userland will be present. This
616: helps to avoid critical errors when upgrading.
1.1 abs 617: Use object directories:
618: This helps to keep stale object
619: files from polluting the build if a Makefile "forgets"
620: about one. It also makes it easier to clean up after
621: a build. It's also necessary if you want to use the
622: same source tree for multiple machines.
1.123 jmc 623: To use object directories with build.sh:
624: a) invoke build.sh with the "-M" or "-O" options.
625: To use object directories without using build.sh:
1.1 abs 626: a) cd /usr/src ; make cleandir
1.2 mrg 627: b) Add "OBJMACHINE=yes" to /etc/mk.conf
628: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 629: d) cd /usr/src ; make build
1.2 mrg 630: Note that running "make obj" in a directory will create
631: in obj.$MACHINE directory.
1.1 abs 632: Build to a DESTDIR:
1.123 jmc 633: This helps to keep old installed files (especially libraries)
634: from interfering with the new build.
635: To build to a DESTDIR with build.sh, use the "-D" option.
636: To build to a DESTDIR without using build.sh, set the DESTDIR
637: environment variable before running make build. It should be
638: set to the pathname of an initially empty directory.
639: Problems: if you do not use build.sh, you might need to
640: update critical utilities without using DESTDIR since
641: nothing is executed from what is installed in DESTDIR.
642: (See critical utils, below.)
1.1 abs 643: Build often:
644: This keeps critical utilities current enough to not choke
645: on any other part of the source tree that depends on up to
1.123 jmc 646: date functionality. If you use build.sh, you should not have
647: this problem.

1.1 abs 649: What to do if things don't work:
650: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 651: When things don't work there are usually a few things that commonly
1.1 abs 652: should be done.
653: 1) make includes
654: This should be done automatically by make build.
655: 2) cd share/mk && make install
656: Again, automatically done by make build.
657:
658: Failsafe rebuild of a small part of the tree:
659: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
660: To make sure you rebuild something correctly you want to do
661: something like the following:
662: 1) Make sure the includes and .mk files are up to date.
663: 2) Make sure any program used to build the particular
664: utility is up to date. (yacc, lex, etc...)
665: 3) cd ...path/to/util...
666: make cleandir
667: rm ...all obj directories...
668: make cleandir # yes, again
669: make obj
670: make depend && make
671:
672: Failsafe rebuild of the entire tree:
673: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
674: If you really want to make sure the source tree is clean and
1.2 mrg 675: ready for a build try the following. Note that sourcing /etc/mk.conf
676: (a make(1) Makefile) in this manner is not right, and will not work
