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.

16: Recent changes:
17: ^^^^^^^^^^^^^^^
1.230 tls 18:
1.249 ! mrg 19: 20131129:
! 20: The GMP sources were updated, and builds will likely fail without
! 21: cleaning their build trees for both tools and in-tree, like below.
! 22:
1.248 mrg 23: 20131128:
24: The MPC and MPFR sources were updated, and builds may require their
25: tools and in-tree directories cleaned for successful updates.
26:
1.246 martin 27: 20130605:
1.247 spz 28: The kernel option FAST_IPSEC no longer exists, it's been renamed
29: to IPSEC (and the older IPSEC version removed).
30:
31: 20130605:
1.246 martin 32: Previous freetype installations eroneously installed private
33: header files. If you are building against a non-empty $DESTDIR,
34: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
35:
1.245 mrg 36: 20130531:
37: The xdm update may cause build failure due to xdm.man being
38: in the obj tree. Make sure to ensure any like this:
39: nbmake: nbmake: don't know how to make xdm.man. Stop
40: is fixed by deleting the xdm.man in the obj tree.
41:
1.244 mrg 42: 20130530:
43: Updates of many xsrc packages will leave old .pc files around.
44: Best to clean out the xsrc objdir entirely before rebuilds.
45:
1.242 christos 46: 20130301:
47: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 48: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 49:
1.238 dholland 50: 20120726:
1.241 wiz 51: The update of OpenSSL requires cleaning both the OpenSSL build
52: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 53: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 54: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 55: cause third-party software to link incorrectly and/or crash.
1.238 dholland 56:
1.237 wiz 57: 20120507:
1.241 wiz 58: The database schema for makemandb was changed. You will
1.237 wiz 59: need to update the database using 'makemandb -f' or wait
60: for the next weekly run to fix it.
61:
1.236 bsh 62: 20120319:
63: sys/conf/Makefile.kern.inc has been modified to adjust the
64: size of db_symtab automatically. You need to update dbsym in
65: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
66: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
67: mk.conf.
68:
1.235 joerg 69: 20120216:
1.241 wiz 70: Default for MKCATPAGES changed to NO. Update builds will fail
71: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 72: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 73: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 74: the next run of weekly will fix it.
1.233 joerg 75:
1.232 christos 76: 20111227:
77: If you built between 20111225 and 20111227 you need to remove
78: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
79: bump has been reverted.
80:
1.231 tls 81: 20111125:
82: The "rnd" pseudodevice has been added to sys/conf/std, which
83: means it should no longer be explicitly listed in kernel
84: configuration files. The line "pseudo-device rnd" should be
85: removed from any custom kernel config files users may have.
86:
1.230 tls 87: 20111119:
88: A problem with the datastructures used by the rndctl(8)
89: utility (pointers in datastructures in an array, making 32->64
90: bit compatibility very painful) has been fixed in a
91: non-backwards-compatible way. If you replace your kernel,
92: replace your rndctl executable too.
1.241 wiz 93:
1.229 jym 94: 20111001:
95: the prop_*_send_syscall() functions from proplib(3) have been
96: changed and their new version is not backward compatible with the old
1.241 wiz 97: one. So ensure that all consumers of these functions (currently:
1.229 jym 98: quota2 code and its tests) are updated together with the new lib.
99:
1.228 mrg 100: 20110817:
101: sparc has been changed to use GCC 4.5.3, so any objdir or
102: DESTDIR for them should be deleted before updating.
103:
1.227 riastrad 104: 20110806:
105: i386 and amd64 have been changed to use GCC 4.5.3, so any
106: objdir or DESTDIR for them should be deleted before updating.
107:
1.226 mrg 108: 20110805:
109: The update to GCC 4.5.3 requires a non-trivial portion of
110: the tree to be cleaned. Best to delete both objdir and
111: DESTDIR before running this update. So far, only the
112: sparc64, mips and powerpc platforms have changed.
113:
1.225 matt 114: 20110803:
1.241 wiz 115: The layout of external/public-domain/xz has changed. To do an
1.225 matt 116: update build you will have to remove the contents of the OBJDIR
117: for external/public-domain/xz/bin by hand as the xz entry there
118: is now a directory.
119:
1.223 joerg 120: 20110410:
1.241 wiz 121: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 122: update build you have to clean both tools/binutils and
123: tools/gcc by hand.
1.223 joerg 124:
1.222 plunky 125: 20110328:
126: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 127: ordering issues with "make all". It may be necessary to remove
1.222 plunky 128: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
129: if your update build fails, as the "Xorg" entry there is now a
130: directory.
131:
1.220 joerg 132: 20110121:
1.221 lukem 133: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 134: the build of individual parts of the tree. This is handled
135: correctly by build.sh. Manual builds have to update /usr/share/mk
136: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 137:
1.217 jruoho 138: 20101217:
139: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 140: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 141: group(5) in order to make the program work with existing setups.
142:
1.216 christos 143: 20101125:
144: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 145: variables with names that contain '='. Revision 1.18 of env.c
146: assumed that this was allowed. Installing a new libc with an
1.216 christos 147: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
148: break which affects the autoconf tests for dependency finding,
149: so building gcc will end up printing:
150: checking dependency style of gcc... none
151: configure: error: no usable dependency style found
152: Fix it by rebuilding and re-installing env.
1.138 lukem 153:
1.215 mrg 154: 20101119:
155: Recent Xorg updates in xsrc/external/mit/ may cause various build
156: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
157: have any build problems with xsrc, or problems with mismatched
158: versions between xorg-server and drivers.
159:
1.213 jmmv 160: 20100604:
161: The update of ATF to 0.9 causes old tests written in shell to fail
162: unless they are rebuilt. If you are building with MKUPDATE=yes,
163: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
164: trees by hand.
165:
1.211 tnozaki 166: 20100522:
1.212 mrg 167: Recent Xorg updates in xsrc/external/mit/ will cause various build
168: problems. Delete your entire DESTDIR and OBJDIR if you have any
169: build problems with xsrc.
170:
171: 20100522:
1.211 tnozaki 172: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 173: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 174:
1.210 christos 175: 20100520:
1.241 wiz 176: The location of the xkb compiled descriptions has changed. Please
1.210 christos 177: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
178:
1.209 njoly 179: 20100222:
180: The shared objects file extension has been changed from .so to
181: .pico, in order to avoid conflicts with shared libraries names
182: libXX.so. All now stale regular .so files can be removed from
183: your object directories.
184:
1.208 roy 185: 20100204:
186: The termcap database has been removed from the sources,
187: but has not been marked obsolete so it is not removed
188: from the system when upgrading.
189: As such, you will need to remove them from your object
190: and destination directories.
191:
1.203 dyoung 192: 20091101:
1.205 dholland 193: After updating, it may be necessary to make the 'cleandir'
194: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
195: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
196: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 197:
1.202 mrg 198: 20091001:
1.206 dholland 199: On amd64 you must rebuild tools (to get the new binutils)
200: before building a kernel, or the build fails on cpufunc.S.
201:
202: 20091001:
1.202 mrg 203: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
204: symlink, failing the build. Delete the link, and the subdir
205: it is in, and retry your build.
206:
1.201 dsl 207: 20090718:
208: libc build changed so that strchr() provides the extra entry
1.241 wiz 209: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 210: may fail because the archive contains the unwanted index.o.
211: (Similarly for strrchr() and rindex().)
212:
1.198 mrg 213: 20090709:
214: Native Xorg was upgraded again. Builds will probably fail again
215: without a clean objdir, at least for src/external/mit/xorg.
216:
1.197 mrg 217: 20090616:
218: Native Xorg was upgraded. Builds will need a clean objdir for
219: src/external/mit/xorg. Upgrading a system from sets will not
220: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
221: subdirectory has been changed into a file, and this needs to
222: be manually "rm -r"'ed before installing xbase.tgz.
223:
1.195 perry 224: 20090501:
225: Several new functions were added to string.h/libc, and this
226: can cause autoconf problems during the tool build for people
1.241 wiz 227: who fail to clean out their tools objects properly. If you
1.195 perry 228: note messages about stpcpy, stpncpy or strnlen accompanying a
229: failure during the tool build, clean out all your tools
230: objects and start again.
231:
1.194 mrg 232: 20090325:
233: The i386 port was switched to i486 default toolchain. This requires
234: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
235:
1.192 skrll 236: 20090126:
1.241 wiz 237: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 238: need to 'rm -f __posix_fadvise50.*' in the libc build directory
239: to avoid using the old assembly stub.
1.192 skrll 240:
1.191 joerg 241: 20090202:
242: pkg_install now depends on the pkgdb cache for automatic conflict
243: detection. It is recommented to rebuild the cache with
244: ``pkg_admin rebuild''.
245:
1.184 christos 246: 20090110:
1.241 wiz 247: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
248: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 249: This is needed even in the MODULAR kernel because there is
250: conditionally compiled code in rtsock.c.
1.184 christos 251: 2. make sure build.sh completes and the binaries in a chroot work
252: before installing.
253: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 254: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 255: are installed properly, and start building libraries first libc
256: and libutil, install them and then continue building all the
1.241 wiz 257: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 258: the new libraries are installed, you can restart the build.
259: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 260: rebuild the required packages to update their shared libraries.
261: Any package you rebuild will require rebuilding all the packages
262: that depend on it.
1.186 christos 263: 5. Next time you run pwd_mkdb with the new binary, the file
264: will be upgraded and it will not be backwards compatible.
1.190 apb 265: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
266: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 267: for utmp. You are better off removing the old files after
1.190 apb 268: upgrading. The automated clearing of /var/run during
269: boot, and the automated rotating of files in /var/log by
270: newsyslog(8), may mean that you do not have to remove the
271: files manually.
272: 7. The optional accounting file (/var/account/acct, see
273: accton(8)) has not been versioned, and will need to be
274: removed. The automatic rotation of the accounting file by
275: /etc/daily limits the bad consequences of failure to remove
276: the file.
1.196 dholland 277: 8. Application software that writes time_t to binary files on
1.241 wiz 278: disk will break or need attention. Most notably: if you are
1.196 dholland 279: using PostgreSQL < 8.4, you need to dump your databases,
280: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 281:
1.183 pgoyette 282: 20081219:
283: config(1) has been updated, and one of the files it creates -
284: swapnetbsd.o - has changed format. You need to rebuild config
285: (done automatically by build.sh) and then you need to rerun
286: config on all kernel configuration files before rebuilding those
287: kernels.
288:
1.181 cube 289: 20081205:
290: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
291: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
292: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 293:
1.179 tsutsui 294: 20081122:
1.182 tsutsui 295: On i386, various kernel options(4) in GENERIC including
1.180 wiz 296: file systems have been disabled and moved into kernel modules.
297: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 298: following files as well as a new GENERIC kernel:
299:
300: - build and install kernel modules from src/sys/modules
301:
302: - install the latest bootloader, which will load a module
1.180 wiz 303: for the file system from which the kernel is loaded automatically
1.179 tsutsui 304:
1.180 wiz 305: If you have to load your kernel from a file system which is not of
306: the same type as the root file system, you have to load the necessary
307: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 308:
1.178 lukem 309: 20080827:
310: If you built and installed a libc from sources between
311: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
312: which results in false errors reported by lint(1).
313: Since this breaks the libc build itself, manual help is
1.180 wiz 314: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 315: $ (cd lib/libc && make MKLINT=no dependall install)
316:
1.177 christos 317: 20080813:
318: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 319: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 320:
1.200 dholland 321: 20080802:
322: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 323: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 324: for -current.
325:
326: Threaded programs (using libpthread) and C++ programs (using
327: libstdc++) compiled after 20070907 and before 20080802 need to
328: be recompiled.
329:
330: One way to find affected pkgsrc packages:
331:
332: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
333: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
334:
1.175 simonb 335: 20080731:
336: WAPBL (metadata journaling support) has been added, but at this
337: time isn't backwards compatible with pre-WAPBL aware kernels
338: and userland (fsck_ffs in particular). Please make sure you
339: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 340: especially an uncleanly mounted journaled filesystem. WAPBL
341: also requires the super block to be in the UFS2 format. You
342: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 343:
1.174 lukem 344: 20080721:
345: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
346: isn't defined.
347:
1.173 freza 348: 20080531:
1.241 wiz 349: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
350: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 351: utility needs to be rebuilt and reinstalled as older binaries
1.241 wiz 352: won't work correctly. The following sequence of commands:
1.173 freza 353:
354: $ (cd sys/sys/ && nbmake-$arch includes)
355: $ (cd sbin/drvctl/ && nbmake-$arch clean)
356: $ (cd sbin/drvctl/ && nbmake-$arch all)
357:
358: leaves new drvctl utility in sbin/drvctl build directory.
359:
1.172 lukem 360: 20080503:
361: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
362:
1.171 he 363: 20080521:
364: For a while, unprivileged UPDATE builds would fail to
365: succeed at the checkflist stage, complaining that
366: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
367: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
368: If you already hit this problem, update the .mk file,
369: remove ${DESTDIR}/stand/<arch>, and re-run the build.
370:
1.174 lukem 371: 20080303:
372: Linker warnings are now fatal if $WARNS>0.
373:
1.170 christos 374: 20080126:
375: The posix_fadvise system call has been changed from an assembly
1.241 wiz 376: stub, to a c file that calls an assembly stub. You need to
1.170 christos 377: 'rm -f posix_fadvise.* .depend' in the libc build directory to
378: avoid using the old assembly stub.
379:
1.168 joerg 380: 20071209:
1.241 wiz 381: The acpiec(4) driver has been split into two attachments. If you
1.168 joerg 382: get ACPI errors before the attachment, please update your kernel
1.169 wiz 383: configuration file appropriately or see GENERIC for more details.
1.168 joerg 384:
1.166 xtraeme 385: 20071115:
386: The it(4) driver has been renamed to itesio(4) and the old port
387: argument specified in the kernel configuration file is not valid
1.241 wiz 388: anymore. The itesio(4) driver now uses the Super I/O address port
389: rather than the EC address port. Please update your kernel
1.167 wiz 390: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 391:
1.165 jmmv 392: 20071028:
393: The pccons(4) driver has been removed from the NetBSD/shark port.
394: You need to update any custom kernel configuration file you have
395: to remove any references to pccons (which includes removing the
396: now useless XSERVER option) and replace them with the correct
397: entries for the wscons driver. See the GENERIC configuration file
398: for more details.

1.164 gdt 400: 20070913:
401: A latent bug in dhclient/dhcpd that caused it to be unable to
402: enumerate interfaces was fixed. The bug began to cause
403: problems after 20070911 when the kernel's SIOCGIFCONF
404: implementation was repaired. From 20070529 to 20070911 racoon
405: could not enumerate interfaces. (These are noted because
406: normal kernel/userspace version matching hygiene is not
407: sufficient to avoid this problem.) Ensure that both kernel
408: and userland are from after 20070913.

1.163 joerg 410: 20070703:
1.241 wiz 411: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
1.199 dholland 412: calls the target-specific strip program, and the logic to pass
413: down STRIP from make has been removed. This requires a
414: re-installation of tools.
1.163 joerg 415:
1.161 dsl 416: 20070422:
417: The way OS emulations lookup filenames inside the emulation root
418: has been changed. Rather than modify the pathname (and copy back
419: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 420: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 421: root file system will be relative to that file system - unless they
1.161 dsl 422: start /../ this is useful when the emulated root is a real install
423: that has such links.
424: This might affect symlinks that have been added to reference outside
425: the emulated root.

1.160 jmcneill 430: example.

433: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
434: on many platforms due to incorrect flags settings. If you
435: updated and built after about 20070315, do "nbmake-$arch
436: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a

1.157 apb 447: 20070209:
448: The threading model was changed when the newlock2 branch
449: was merged to NetBSD-current. If you boot with a new
450: kernel (version 4.99.10), then you also need a new pthread
451: library (/usr/lib/libpthread.so.0.7). If you boot with
452: an old kernel, then you need the old pthread library
453: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
454: the pthread library in sync, old threaded applications should
455: continue to work with an old or new kernel. Note that named(8)
456: is the only threaded application in the base system.

471: changed to indicate that our libc has ssp support built-in and
1.241 wiz 472: does not depend on -lssp and -lssp-nonshared. You'll need to
1.152 christos 473: make clean in src/tools/gcc first to rebuild the compiler.

1.150 bjh21 479: 20060814:
480: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
481: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
482: kernel configuration for an example. X servers from the last
483: few years should cope.

1.241 wiz 486: MPACPI is no more. We always configure PCI interrupts using ACPI
487: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
488: to ACPI_SCANPCI. Thanks to work from fvdl.

1.148 dogcow 490: 20060627:
491: socket(2) has changed, and its system call has been versioned.
492: For userlands with the old version of socket(2), make sure that
493: your kernel has 'options COMPAT_30' set, or else 'bad system call'
494: errors will result.

1.1 abs 496: Hints for a more successful build:
497: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 498: Use build.sh, but do not use its "expert mode":
1.132 jmmv 499: This will automatically build the tools in the
1.123 jmc 500: correct order, and it will keep the tools and the
501: new build products from interfering with the running
502: system. This will allow you to ignore most of the
503: other advice in this file.
1.2 mrg 504: Build a new kernel first:
505: This makes sure that any new system calls or features
506: expected by the new userland will be present. This
507: helps to avoid critical errors when upgrading.
1.1 abs 508: Use object directories:
509: This helps to keep stale object
510: files from polluting the build if a Makefile "forgets"
511: about one. It also makes it easier to clean up after
512: a build. It's also necessary if you want to use the
513: same source tree for multiple machines.
1.123 jmc 514: To use object directories with build.sh:
515: a) invoke build.sh with the "-M" or "-O" options.
516: To use object directories without using build.sh:
1.1 abs 517: a) cd /usr/src ; make cleandir
1.2 mrg 518: b) Add "OBJMACHINE=yes" to /etc/mk.conf
519: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 520: d) cd /usr/src ; make build
1.2 mrg 521: Note that running "make obj" in a directory will create
522: in obj.$MACHINE directory.
1.1 abs 523: Build to a DESTDIR:
1.123 jmc 524: This helps to keep old installed files (especially libraries)
525: from interfering with the new build.
526: To build to a DESTDIR with build.sh, use the "-D" option.
527: To build to a DESTDIR without using build.sh, set the DESTDIR
528: environment variable before running make build. It should be
529: set to the pathname of an initially empty directory.
530: Problems: if you do not use build.sh, you might need to
531: update critical utilities without using DESTDIR since
532: nothing is executed from what is installed in DESTDIR.
533: (See critical utils, below.)
1.1 abs 534: Build often:
535: This keeps critical utilities current enough to not choke
536: on any other part of the source tree that depends on up to
1.123 jmc 537: date functionality. If you use build.sh, you should not have
538: this problem.
1.241 wiz 539:
1.1 abs 540: What to do if things don't work:
541: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 542: When things don't work there are usually a few things that commonly
1.1 abs 543: should be done.
544: 1) make includes
545: This should be done automatically by make build.
546: 2) cd share/mk && make install
547: Again, automatically done by make build.
548:
549: Failsafe rebuild of a small part of the tree:
550: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
551: To make sure you rebuild something correctly you want to do
552: something like the following:
553: 1) Make sure the includes and .mk files are up to date.
554: 2) Make sure any program used to build the particular
555: utility is up to date. (yacc, lex, etc...)
556: 3) cd ...path/to/util...
557: make cleandir
558: rm ...all obj directories...
559: make cleandir # yes, again
560: make obj
561: make depend && make
562:
563: Failsafe rebuild of the entire tree:
564: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
565: If you really want to make sure the source tree is clean and
1.2 mrg 566: ready for a build try the following. Note that sourcing /etc/mk.conf
567: (a make(1) Makefile) in this manner is not right, and will not work
568: for anyone who uses any make(1) features in /etc/mk.conf.
