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.

20: ^^^^^^^^^^^^^^^
1.230 tls 21:
1.264 ! martin 22: 20160125:
! 23: Dtrace has been enabled by default on some architectures.
! 24: When doing an update build, make sure to clean the etc/mtree
! 25: object directory before starting the build - otherwise the
! 26: needed directories in destdir will not be created.
! 27: An easy way to do this is:
! 28: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
! 29:
1.263 dholland 30: 20150818:
31: New acpica requires "make cleandir" in src/external/bsd/acpica
32: again.
33:
1.262 christos 34: 20150413:
35: New acpica requires "make cleandir" and reinstalling yacc
36: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
37: also "make cleandir" in /usr/src/external/bsd/acpica.
38:
1.261 martin 39: 20150404:
40: Lint changes require a full rebuild of the tool, so make
41: sure to build without -u option to build.sh, or manually
42: do a make cleandir in src/tools/lint1 and
43: src/usr.bin/xlint.
44:
1.260 skrll 45: 20150310:
46: Improvements to openssl for arm mean that update builds of
47: the openssl libraries will fail. A make cleandir in
48: external/bsd/openssl/lib is needed
49:
1.258 martin 50: 20141026:
1.259 msaitoh 51: A mishap during the import of pppd may cause your corruption
1.258 martin 52: in your cvs directory if you happened to do a cvs update
53: during a short period of time. To fix, just remove the
54: directory src/external/bsd/ppp/dist/pppd completely
55: and let cvs restore it on next update.
56:
1.256 apb 57: 20140721:
58: The src/external/mit/lua/src directory was accidentally created
59: and then deleted in the CVS repository. If you get errors like
60:
61: cvs [update aborted]: cannot open directory
62: /cvsroot/src/external/mit/lua/src: No such file or directory
63:
64: then delete your local copy of that directory tree and try again.
65:
1.255 joerg 66: 20140530:
67: ARM eABI switched to DWARF based exception handling. This requires
68: rebuilding all C++ code. It is strongly advised to do a clean build.
69:
1.251 martin 70: 20140131:
1.253 joerg 71: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 72: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 73: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 74:
1.250 christos 75: 20131227:
76: 1. The new ntpd runs in a restricted mode to prevent amplification
77: attacks. If you need ntpdc to work you need to explicitly enable
78: mode7 in your config file. Make sure you put the necessary restrict
79: statements to avoid being exposed.
80: 2. strncat has moved from lib/libc to common/lib/libc; you might need
81: to make clean in libc
82:
1.249 mrg 83: 20131129:
84: The GMP sources were updated, and builds will likely fail without
85: cleaning their build trees for both tools and in-tree, like below.
86:
1.248 mrg 87: 20131128:
88: The MPC and MPFR sources were updated, and builds may require their
89: tools and in-tree directories cleaned for successful updates.
90:
1.246 martin 91: 20130605:
1.247 spz 92: The kernel option FAST_IPSEC no longer exists, it's been renamed
93: to IPSEC (and the older IPSEC version removed).
94:
95: 20130605:
1.246 martin 96: Previous freetype installations eroneously installed private
97: header files. If you are building against a non-empty $DESTDIR,
98: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
99:
1.245 mrg 100: 20130531:
101: The xdm update may cause build failure due to xdm.man being
102: in the obj tree. Make sure to ensure any like this:
103: nbmake: nbmake: don't know how to make xdm.man. Stop
104: is fixed by deleting the xdm.man in the obj tree.
105:
1.244 mrg 106: 20130530:
107: Updates of many xsrc packages will leave old .pc files around.
108: Best to clean out the xsrc objdir entirely before rebuilds.
109:
1.242 christos 110: 20130301:
111: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 112: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 113:
1.238 dholland 114: 20120726:
1.241 wiz 115: The update of OpenSSL requires cleaning both the OpenSSL build
116: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 117: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 118: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 119: cause third-party software to link incorrectly and/or crash.
1.238 dholland 120:
1.237 wiz 121: 20120507:
1.241 wiz 122: The database schema for makemandb was changed. You will
1.237 wiz 123: need to update the database using 'makemandb -f' or wait
124: for the next weekly run to fix it.
125:
1.236 bsh 126: 20120319:
127: sys/conf/Makefile.kern.inc has been modified to adjust the
128: size of db_symtab automatically. You need to update dbsym in
129: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
130: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
131: mk.conf.
132:
1.235 joerg 133: 20120216:
1.241 wiz 134: Default for MKCATPAGES changed to NO. Update builds will fail
135: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 136: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 137: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 138: the next run of weekly will fix it.
1.233 joerg 139:
1.232 christos 140: 20111227:
141: If you built between 20111225 and 20111227 you need to remove
142: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
143: bump has been reverted.
144:
1.231 tls 145: 20111125:
146: The "rnd" pseudodevice has been added to sys/conf/std, which
147: means it should no longer be explicitly listed in kernel
148: configuration files. The line "pseudo-device rnd" should be
149: removed from any custom kernel config files users may have.
150:
1.230 tls 151: 20111119:
152: A problem with the datastructures used by the rndctl(8)
153: utility (pointers in datastructures in an array, making 32->64
154: bit compatibility very painful) has been fixed in a
155: non-backwards-compatible way. If you replace your kernel,
156: replace your rndctl executable too.
1.241 wiz 157:
1.229 jym 158: 20111001:
159: the prop_*_send_syscall() functions from proplib(3) have been
160: changed and their new version is not backward compatible with the old
1.241 wiz 161: one. So ensure that all consumers of these functions (currently:
1.229 jym 162: quota2 code and its tests) are updated together with the new lib.
163:
1.228 mrg 164: 20110817:
165: sparc has been changed to use GCC 4.5.3, so any objdir or
166: DESTDIR for them should be deleted before updating.
167:
1.227 riastrad 168: 20110806:
169: i386 and amd64 have been changed to use GCC 4.5.3, so any
170: objdir or DESTDIR for them should be deleted before updating.
171:
1.226 mrg 172: 20110805:
173: The update to GCC 4.5.3 requires a non-trivial portion of
174: the tree to be cleaned. Best to delete both objdir and
175: DESTDIR before running this update. So far, only the
176: sparc64, mips and powerpc platforms have changed.
177:
1.225 matt 178: 20110803:
1.241 wiz 179: The layout of external/public-domain/xz has changed. To do an
1.225 matt 180: update build you will have to remove the contents of the OBJDIR
181: for external/public-domain/xz/bin by hand as the xz entry there
182: is now a directory.
183:
1.223 joerg 184: 20110410:
1.241 wiz 185: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 186: update build you have to clean both tools/binutils and
187: tools/gcc by hand.
1.223 joerg 188:
1.222 plunky 189: 20110328:
190: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 191: ordering issues with "make all". It may be necessary to remove
1.222 plunky 192: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
193: if your update build fails, as the "Xorg" entry there is now a
194: directory.
195:
1.220 joerg 196: 20110121:
1.221 lukem 197: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 198: the build of individual parts of the tree. This is handled
199: correctly by build.sh. Manual builds have to update /usr/share/mk
200: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 201:
1.217 jruoho 202: 20101217:
203: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 204: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 205: group(5) in order to make the program work with existing setups.
206:
1.216 christos 207: 20101125:
208: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 209: variables with names that contain '='. Revision 1.18 of env.c
210: assumed that this was allowed. Installing a new libc with an
1.216 christos 211: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
212: break which affects the autoconf tests for dependency finding,
213: so building gcc will end up printing:
214: checking dependency style of gcc... none
215: configure: error: no usable dependency style found
216: Fix it by rebuilding and re-installing env.
1.138 lukem 217:
1.215 mrg 218: 20101119:
219: Recent Xorg updates in xsrc/external/mit/ may cause various build
220: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
221: have any build problems with xsrc, or problems with mismatched
222: versions between xorg-server and drivers.
223:
1.213 jmmv 224: 20100604:
225: The update of ATF to 0.9 causes old tests written in shell to fail
226: unless they are rebuilt. If you are building with MKUPDATE=yes,
227: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
228: trees by hand.
229:
1.211 tnozaki 230: 20100522:
1.212 mrg 231: Recent Xorg updates in xsrc/external/mit/ will cause various build
232: problems. Delete your entire DESTDIR and OBJDIR if you have any
233: build problems with xsrc.
234:
235: 20100522:
1.211 tnozaki 236: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 237: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 238:
1.210 christos 239: 20100520:
1.241 wiz 240: The location of the xkb compiled descriptions has changed. Please
1.210 christos 241: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
242:
1.209 njoly 243: 20100222:
244: The shared objects file extension has been changed from .so to
245: .pico, in order to avoid conflicts with shared libraries names
246: libXX.so. All now stale regular .so files can be removed from
247: your object directories.
248:
1.208 roy 249: 20100204:
250: The termcap database has been removed from the sources,
251: but has not been marked obsolete so it is not removed
252: from the system when upgrading.
253: As such, you will need to remove them from your object
254: and destination directories.
255:
1.203 dyoung 256: 20091101:
1.205 dholland 257: After updating, it may be necessary to make the 'cleandir'
258: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
259: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
260: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 261:
1.202 mrg 262: 20091001:
1.206 dholland 263: On amd64 you must rebuild tools (to get the new binutils)
264: before building a kernel, or the build fails on cpufunc.S.
265:
266: 20091001:
1.202 mrg 267: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
268: symlink, failing the build. Delete the link, and the subdir
269: it is in, and retry your build.
270:
1.201 dsl 271: 20090718:
272: libc build changed so that strchr() provides the extra entry
1.241 wiz 273: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 274: may fail because the archive contains the unwanted index.o.
275: (Similarly for strrchr() and rindex().)
276:
1.198 mrg 277: 20090709:
278: Native Xorg was upgraded again. Builds will probably fail again
279: without a clean objdir, at least for src/external/mit/xorg.
280:
1.197 mrg 281: 20090616:
282: Native Xorg was upgraded. Builds will need a clean objdir for
283: src/external/mit/xorg. Upgrading a system from sets will not
284: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
285: subdirectory has been changed into a file, and this needs to
286: be manually "rm -r"'ed before installing xbase.tgz.
287:
1.195 perry 288: 20090501:
289: Several new functions were added to string.h/libc, and this
290: can cause autoconf problems during the tool build for people
1.241 wiz 291: who fail to clean out their tools objects properly. If you
1.195 perry 292: note messages about stpcpy, stpncpy or strnlen accompanying a
293: failure during the tool build, clean out all your tools
294: objects and start again.
295:
1.194 mrg 296: 20090325:
297: The i386 port was switched to i486 default toolchain. This requires
298: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
299:
1.192 skrll 300: 20090126:
1.241 wiz 301: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 302: need to 'rm -f __posix_fadvise50.*' in the libc build directory
303: to avoid using the old assembly stub.
1.192 skrll 304:
1.191 joerg 305: 20090202:
306: pkg_install now depends on the pkgdb cache for automatic conflict
307: detection. It is recommented to rebuild the cache with
308: ``pkg_admin rebuild''.
309:
1.184 christos 310: 20090110:
1.241 wiz 311: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
312: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 313: This is needed even in the MODULAR kernel because there is
314: conditionally compiled code in rtsock.c.
1.184 christos 315: 2. make sure build.sh completes and the binaries in a chroot work
316: before installing.
317: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 318: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 319: are installed properly, and start building libraries first libc
320: and libutil, install them and then continue building all the
1.241 wiz 321: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 322: the new libraries are installed, you can restart the build.
323: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 324: rebuild the required packages to update their shared libraries.
325: Any package you rebuild will require rebuilding all the packages
326: that depend on it.
1.186 christos 327: 5. Next time you run pwd_mkdb with the new binary, the file
328: will be upgraded and it will not be backwards compatible.
1.190 apb 329: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
330: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 331: for utmp. You are better off removing the old files after
1.190 apb 332: upgrading. The automated clearing of /var/run during
333: boot, and the automated rotating of files in /var/log by
334: newsyslog(8), may mean that you do not have to remove the
335: files manually.
336: 7. The optional accounting file (/var/account/acct, see
337: accton(8)) has not been versioned, and will need to be
338: removed. The automatic rotation of the accounting file by
339: /etc/daily limits the bad consequences of failure to remove
340: the file.
1.196 dholland 341: 8. Application software that writes time_t to binary files on
1.241 wiz 342: disk will break or need attention. Most notably: if you are
1.196 dholland 343: using PostgreSQL < 8.4, you need to dump your databases,
344: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 345:
1.183 pgoyette 346: 20081219:
347: config(1) has been updated, and one of the files it creates -
348: swapnetbsd.o - has changed format. You need to rebuild config
349: (done automatically by build.sh) and then you need to rerun
350: config on all kernel configuration files before rebuilding those
351: kernels.
352:
1.181 cube 353: 20081205:
354: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
355: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
356: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 357:
1.179 tsutsui 358: 20081122:
1.182 tsutsui 359: On i386, various kernel options(4) in GENERIC including
1.180 wiz 360: file systems have been disabled and moved into kernel modules.
361: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 362: following files as well as a new GENERIC kernel:
363:
364: - build and install kernel modules from src/sys/modules
365:
366: - install the latest bootloader, which will load a module
1.180 wiz 367: for the file system from which the kernel is loaded automatically
1.179 tsutsui 368:
1.180 wiz 369: If you have to load your kernel from a file system which is not of
370: the same type as the root file system, you have to load the necessary
371: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 372:
1.178 lukem 373: 20080827:
374: If you built and installed a libc from sources between
375: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
376: which results in false errors reported by lint(1).
377: Since this breaks the libc build itself, manual help is
1.180 wiz 378: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 379: $ (cd lib/libc && make MKLINT=no dependall install)
380:
1.177 christos 381: 20080813:
382: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 383: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 384:
1.200 dholland 385: 20080802:
386: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 387: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 388: for -current.
389:
390: Threaded programs (using libpthread) and C++ programs (using
391: libstdc++) compiled after 20070907 and before 20080802 need to
392: be recompiled.
393:
394: One way to find affected pkgsrc packages:
395:
396: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
397: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
398:

400: WAPBL (metadata journaling support) has been added, but at this
401: time isn't backwards compatible with pre-WAPBL aware kernels
402: and userland (fsck_ffs in particular). Please make sure you
403: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 404: especially an uncleanly mounted journaled filesystem. WAPBL
405: also requires the super block to be in the UFS2 format. You
406: can use fsck_ffs -c 4 to update the superblock format.

1.241 wiz 413: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
414: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 415: utility needs to be rebuilt and reinstalled as older binaries

1.241 wiz 445: The acpiec(4) driver has been split into two attachments. If you
1.168 joerg 446: get ACPI errors before the attachment, please update your kernel
1.169 wiz 447: configuration file appropriately or see GENERIC for more details.
1.168 joerg 448:
1.166 xtraeme 449: 20071115:
450: The it(4) driver has been renamed to itesio(4) and the old port
451: argument specified in the kernel configuration file is not valid
1.241 wiz 452: anymore. The itesio(4) driver now uses the Super I/O address port
453: rather than the EC address port. Please update your kernel
1.167 wiz 454: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 455:
1.165 jmmv 456: 20071028:
457: The pccons(4) driver has been removed from the NetBSD/shark port.
458: You need to update any custom kernel configuration file you have
459: to remove any references to pccons (which includes removing the
460: now useless XSERVER option) and replace them with the correct
461: entries for the wscons driver. See the GENERIC configuration file
462: for more details.

1.164 gdt 464: 20070913:
465: A latent bug in dhclient/dhcpd that caused it to be unable to
466: enumerate interfaces was fixed. The bug began to cause
467: problems after 20070911 when the kernel's SIOCGIFCONF
468: implementation was repaired. From 20070529 to 20070911 racoon
469: could not enumerate interfaces. (These are noted because
470: normal kernel/userspace version matching hygiene is not
471: sufficient to avoid this problem.) Ensure that both kernel
472: and userland are from after 20070913.
473:

1.241 wiz 475: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
1.199 dholland 476: calls the target-specific strip program, and the logic to pass
477: down STRIP from make has been removed. This requires a
478: re-installation of tools.
1.163 joerg 479:
1.161 dsl 480: 20070422:
481: The way OS emulations lookup filenames inside the emulation root
482: has been changed. Rather than modify the pathname (and copy back
483: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 484: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 485: root file system will be relative to that file system - unless they
1.161 dsl 486: start /../ this is useful when the emulated root is a real install
487: that has such links.
488: This might affect symlinks that have been added to reference outside
489: the emulated root.

497: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so

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

512: The threading model was changed when the newlock2 branch
513: was merged to NetBSD-current. If you boot with a new
514: kernel (version 4.99.10), then you also need a new pthread
515: library (/usr/lib/libpthread.so.0.7). If you boot with
516: an old kernel, then you need the old pthread library
517: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
518: the pthread library in sync, old threaded applications should
519: continue to work with an old or new kernel. Note that named(8)
520: is the only threaded application in the base system.

534: The configure script used in the src/tools/gcc compiler has been
535: changed to indicate that our libc has ssp support built-in and
1.241 wiz 536: does not depend on -lssp and -lssp-nonshared. You'll need to
1.152 christos 537: make clean in src/tools/gcc first to rebuild the compiler.

1.150 bjh21 543: 20060814:
544: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
545: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC

1.1 abs 560: Hints for a more successful build:
561: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 562: Use build.sh, but do not use its "expert mode":
1.132 jmmv 563: This will automatically build the tools in the
1.123 jmc 564: correct order, and it will keep the tools and the
565: new build products from interfering with the running
566: system. This will allow you to ignore most of the
567: other advice in this file.
1.2 mrg 568: Build a new kernel first:
569: This makes sure that any new system calls or features
570: expected by the new userland will be present. This
571: helps to avoid critical errors when upgrading.
1.1 abs 572: Use object directories:
573: This helps to keep stale object
574: files from polluting the build if a Makefile "forgets"
575: about one. It also makes it easier to clean up after
576: a build. It's also necessary if you want to use the
577: same source tree for multiple machines.
1.123 jmc 578: To use object directories with build.sh:
579: a) invoke build.sh with the "-M" or "-O" options.
580: To use object directories without using build.sh:
1.1 abs 581: a) cd /usr/src ; make cleandir
1.2 mrg 582: b) Add "OBJMACHINE=yes" to /etc/mk.conf
583: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 584: d) cd /usr/src ; make build
1.2 mrg 585: Note that running "make obj" in a directory will create
586: in obj.$MACHINE directory.
1.1 abs 587: Build to a DESTDIR:
1.123 jmc 588: This helps to keep old installed files (especially libraries)
589: from interfering with the new build.
590: To build to a DESTDIR with build.sh, use the "-D" option.
591: To build to a DESTDIR without using build.sh, set the DESTDIR
592: environment variable before running make build. It should be
593: set to the pathname of an initially empty directory.
594: Problems: if you do not use build.sh, you might need to
595: update critical utilities without using DESTDIR since
596: nothing is executed from what is installed in DESTDIR.
597: (See critical utils, below.)
1.1 abs 598: Build often:
599: This keeps critical utilities current enough to not choke
600: on any other part of the source tree that depends on up to
1.123 jmc 601: date functionality. If you use build.sh, you should not have
602: this problem.
1.241 wiz 603:
1.1 abs 604: What to do if things don't work:
605: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 606: When things don't work there are usually a few things that commonly
1.1 abs 607: should be done.
608: 1) make includes
609: This should be done automatically by make build.
610: 2) cd share/mk && make install
611: Again, automatically done by make build.
612:
613: Failsafe rebuild of a small part of the tree:
614: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
615: To make sure you rebuild something correctly you want to do
616: something like the following:
617: 1) Make sure the includes and .mk files are up to date.
618: 2) Make sure any program used to build the particular
619: utility is up to date. (yacc, lex, etc...)
620: 3) cd ...path/to/util...
621: make cleandir
622: rm ...all obj directories...
623: make cleandir # yes, again
624: make obj
625: make depend && make
626:
627: Failsafe rebuild of the entire tree:
628: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
629: If you really want to make sure the source tree is clean and
1.2 mrg 630: ready for a build try the following. Note that sourcing /etc/mk.conf
631: (a make(1) Makefile) in this manner is not right, and will not work
