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:
1.299 ! mrg 22: 20190207:
! 23: GCC 7 switched for many ports. Update builds are likely to fail.
! 24:
1.298 martin 25: 20180924:
26: A newer OpenSSL version has been imported. If you are doing
27: update builds, make sure to remove all old obj dirs, like:
28: cd /usr/obj && find . -type d -name openssl | xargs rm -rf
29:
1.297 joerg 30: 20180717:
31: On aarch64 int64_t and related types have changed from long long
32: to long. This requires recompiling all C++ binaries.
33:
1.296 martin 34: 20180713:
35: On amd64 and i386 static binaries are now build position
36: independend. This requires recompilation of all object
37: files used to create the crunched /rescue binary.
38: Clean the rescue directory in your obj directory before
39: doing an update build, otherwise linking will fail.
40:
1.293 jakllsch 41: 20180414:
42: Existing binutils was migrated to binutils.old. Manual
43: removal of tools/binutils objects directory may be required
44: to fix tools build failure.
45:
1.292 mrg 46: 20180311:
47: bdftopcf was updated and may need cleaning in the
48: src/external/mit/xorg/tools/bdftopcf subdirectory if there are
49: link errors.
50:
1.291 mrg 51: 20180212:
52: between OpenSSL and GCC updates, many things may fail to build.
53: any failure that looks like GCC or openssl is best handled by
54: a clean destdir and objdir. Full cleandir and destdir deletion
55: is recommended if build failures occur.
56:
1.288 martin 57: 20171225:
58: removal of the vadvise syscall requires manual removal of all
59: associated files from the libc build object directory (including
1.289 christos 60: the .depend files) - a command like:
1.288 martin 61: cd $OBJ && find . -type d -name libc | xargs rm -rf
1.289 christos 62: For architectures that support multiple "compat" binary targets,
63: you'll need to cleanup both the regular libc directory and the
1.290 martin 64: compat ones (the above command will do that).
1.288 martin 65:
1.287 kre 66: 20171010:
67: a change to the build structure of external/bsd/acpica/bin/iasl
68: means that its objdir (or *.d and .depend at least) might need
69: to be manually removed - or a build done once without -u.
70:
1.286 mrg 71: 20170822:
72: a new version of GMP has been imported and probably
73: will break parts of builds related to themselves or GCC, both
74: in the tools and the native section. Remove all GCC, GMP, MPFR
75: and MPC objdirs or build once without -u.
76:
1.285 mrg 77: 20170816:
78: a new version of MPFR and MPC have been imported and probably
79: will break parts of builds related to themselves or GCC, both
80: in the tools and the native section. Remove all GCC, GMP, MPFR
81: and MPC objdirs or build once without -u.
82:
1.284 martin 83: 20170402:
84: a new version of dhcpcd has been imported, which does not support
85: update builds from the previous version. Remove your
86: external/bsd/dhcpcd object dir or build once without -u.
87:
1.281 roy 88: 20170211:
89: a new terminfo database has been imported.
90: The structure of it has changed slightly from prior versions and
91: an updated tic tool is required.
92: If you build.sh, don't use -u
93:
1.280 kre 94: 20170207:
1.278 kre 95: various arch dependent libc/exect.S files were removed
1.279 kre 96: Either remove the obj directories (lib/libc and compat/amd64/i386/lib
97: if it exists) or do a clean build.
98: (This is a bug in the make system, it should be corrected without
99: human intervention, but isn't.)
1.278 kre 100:
1.277 martin 101: 20170104:
102: xinput build options have changed.
103: Remove the obj directory (external/mit/xorg/bin/xinput)
104: if you build.sh -u
105:
1.276 martin 106: 20170103:
107: a new version of flex has been imported.
108: Remove the file from obj (external/bsd/flex)
109: if you build.sh -u
110:
1.275 spz 111: 20161014:
112: a new version of OpenSSL has been imported.
113: Remove the files from obj (crypto/external/bsd/openssl)
114: if you build.sh -u
115:
1.274 martin 116: 20161009:
117: a new version of dhcpcd has been imported with slightly changed
118: build infrastructure. When doing a build.sh -u this requires
119: pruning the external/bsd/dhcpcd objdir.
120:
1.273 mrg 121: 20160914:
122: i386, amd64, shark, ofppc and macppc have joined shark and x68k
123: ports in using xorg-server 1.18. This requires a clean destdir
124: and a clean objdir.
125:
1.272 dholland 126: 20160527:
127: i386 needs a full cleandir or objdir deletion because PIE has
128: been enabled. (see the amd64 entry two down for further info)
129:
1.270 christos 130: 20160418:
131: libedit needs manual removal of all autogenerated files since
1.271 christos 132: some of them are not autogenerated anymore. Remember that there
133: might be two copies of libedit if your platform builds "compat".
1.270 christos 134:
1.268 riastrad 135: 20160410:
136: amd64 needs full "make cleandir" or deletion of objdir now that
137: PIE has been enabled for amd64. PIE, or position-independent
138: executables, means all code, including executables and not just
139: shared libraries, is position-independent and hence able to be
140: relocated by ASLR, address space layout randomization.
141:
142: The change was made in Makefile variables for compiler and
143: linker flags, for which make(1) does not record dependencies,
144: hence it is unable to detect that all .o files need rebuilding.
145:
146: Partial rebuilds with some modified source files will likely
147: fail when linking executables, since the linker refuses to mix
148: position-independent code with position-dependent code in
149: position-independent executables:
150:
151: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
152:
1.267 mrg 153: 20160401:
154: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 155: Some people have found that cleandir is not sufficient, so if
156: in doubt delete the entire object directory tree for gcc.
1.267 mrg 157:
1.266 aymeric 158: 20160306:
1.265 aymeric 159: NetBSD's regexp implementation is now part of libnbcompat.
160: Nblex, nbm4, nbpax, nbsed use it and they may crash on
161: non-NetBSD hosts if linked with stale object files produced
162: while they included a non-NetBSD regex.h.
163: In any case, you should "make cleandir" at least these tools
164: before updating your toolchain.
165:
1.264 martin 166: 20160125:
167: Dtrace has been enabled by default on some architectures.
168: When doing an update build, make sure to clean the etc/mtree
169: object directory before starting the build - otherwise the
170: needed directories in destdir will not be created.
171: An easy way to do this is:
172: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
173:
1.263 dholland 174: 20150818:
175: New acpica requires "make cleandir" in src/external/bsd/acpica
176: again.
177:
1.262 christos 178: 20150413:
179: New acpica requires "make cleandir" and reinstalling yacc
180: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
181: also "make cleandir" in /usr/src/external/bsd/acpica.
182:
1.261 martin 183: 20150404:
184: Lint changes require a full rebuild of the tool, so make
185: sure to build without -u option to build.sh, or manually
186: do a make cleandir in src/tools/lint1 and
187: src/usr.bin/xlint.
188:
1.260 skrll 189: 20150310:
190: Improvements to openssl for arm mean that update builds of
191: the openssl libraries will fail. A make cleandir in
192: external/bsd/openssl/lib is needed
193:
1.258 martin 194: 20141026:
1.259 msaitoh 195: A mishap during the import of pppd may cause your corruption
1.258 martin 196: in your cvs directory if you happened to do a cvs update
197: during a short period of time. To fix, just remove the
198: directory src/external/bsd/ppp/dist/pppd completely
199: and let cvs restore it on next update.
200:
1.256 apb 201: 20140721:
202: The src/external/mit/lua/src directory was accidentally created
203: and then deleted in the CVS repository. If you get errors like
204:
205: cvs [update aborted]: cannot open directory
206: /cvsroot/src/external/mit/lua/src: No such file or directory
207:
208: then delete your local copy of that directory tree and try again.
209:
1.255 joerg 210: 20140530:
211: ARM eABI switched to DWARF based exception handling. This requires
212: rebuilding all C++ code. It is strongly advised to do a clean build.
213:
1.251 martin 214: 20140131:
1.253 joerg 215: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 216: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 217: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 218:
1.250 christos 219: 20131227:
220: 1. The new ntpd runs in a restricted mode to prevent amplification
221: attacks. If you need ntpdc to work you need to explicitly enable
222: mode7 in your config file. Make sure you put the necessary restrict
223: statements to avoid being exposed.
224: 2. strncat has moved from lib/libc to common/lib/libc; you might need
225: to make clean in libc
226:
1.249 mrg 227: 20131129:
228: The GMP sources were updated, and builds will likely fail without
229: cleaning their build trees for both tools and in-tree, like below.
230:
1.248 mrg 231: 20131128:
232: The MPC and MPFR sources were updated, and builds may require their
233: tools and in-tree directories cleaned for successful updates.
234:
1.246 martin 235: 20130605:
1.247 spz 236: The kernel option FAST_IPSEC no longer exists, it's been renamed
237: to IPSEC (and the older IPSEC version removed).
238:
239: 20130605:
1.246 martin 240: Previous freetype installations eroneously installed private
241: header files. If you are building against a non-empty $DESTDIR,
242: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
243:
1.245 mrg 244: 20130531:
245: The xdm update may cause build failure due to xdm.man being
246: in the obj tree. Make sure to ensure any like this:
247: nbmake: nbmake: don't know how to make xdm.man. Stop
248: is fixed by deleting the xdm.man in the obj tree.
249:
1.244 mrg 250: 20130530:
251: Updates of many xsrc packages will leave old .pc files around.
252: Best to clean out the xsrc objdir entirely before rebuilds.
253:
1.242 christos 254: 20130301:
255: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 256: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 257:
1.238 dholland 258: 20120726:
1.241 wiz 259: The update of OpenSSL requires cleaning both the OpenSSL build
260: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 261: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 262: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 263: cause third-party software to link incorrectly and/or crash.
1.238 dholland 264:
1.237 wiz 265: 20120507:
1.241 wiz 266: The database schema for makemandb was changed. You will
1.237 wiz 267: need to update the database using 'makemandb -f' or wait
268: for the next weekly run to fix it.
269:
1.236 bsh 270: 20120319:
271: sys/conf/Makefile.kern.inc has been modified to adjust the
272: size of db_symtab automatically. You need to update dbsym in
273: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
274: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
275: mk.conf.
276:
1.235 joerg 277: 20120216:
1.241 wiz 278: Default for MKCATPAGES changed to NO. Update builds will fail
279: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 280: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 281: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 282: the next run of weekly will fix it.
1.233 joerg 283:
1.232 christos 284: 20111227:
285: If you built between 20111225 and 20111227 you need to remove
286: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
287: bump has been reverted.
288:
1.231 tls 289: 20111125:
290: The "rnd" pseudodevice has been added to sys/conf/std, which
291: means it should no longer be explicitly listed in kernel
292: configuration files. The line "pseudo-device rnd" should be
293: removed from any custom kernel config files users may have.
294:
1.230 tls 295: 20111119:
296: A problem with the datastructures used by the rndctl(8)
297: utility (pointers in datastructures in an array, making 32->64
298: bit compatibility very painful) has been fixed in a
299: non-backwards-compatible way. If you replace your kernel,
300: replace your rndctl executable too.
1.241 wiz 301:
1.229 jym 302: 20111001:
303: the prop_*_send_syscall() functions from proplib(3) have been
304: changed and their new version is not backward compatible with the old
1.241 wiz 305: one. So ensure that all consumers of these functions (currently:
1.229 jym 306: quota2 code and its tests) are updated together with the new lib.
307:
1.228 mrg 308: 20110817:
309: sparc has been changed to use GCC 4.5.3, so any objdir or
310: DESTDIR for them should be deleted before updating.
311:
1.227 riastrad 312: 20110806:
313: i386 and amd64 have been changed to use GCC 4.5.3, so any
314: objdir or DESTDIR for them should be deleted before updating.
315:
1.226 mrg 316: 20110805:
317: The update to GCC 4.5.3 requires a non-trivial portion of
318: the tree to be cleaned. Best to delete both objdir and
319: DESTDIR before running this update. So far, only the
320: sparc64, mips and powerpc platforms have changed.
321:
1.225 matt 322: 20110803:
1.241 wiz 323: The layout of external/public-domain/xz has changed. To do an
1.225 matt 324: update build you will have to remove the contents of the OBJDIR
325: for external/public-domain/xz/bin by hand as the xz entry there
326: is now a directory.
327:
1.223 joerg 328: 20110410:
1.241 wiz 329: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 330: update build you have to clean both tools/binutils and
331: tools/gcc by hand.
1.223 joerg 332:
1.222 plunky 333: 20110328:
334: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 335: ordering issues with "make all". It may be necessary to remove
1.222 plunky 336: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
337: if your update build fails, as the "Xorg" entry there is now a
338: directory.
339:
1.220 joerg 340: 20110121:
1.221 lukem 341: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 342: the build of individual parts of the tree. This is handled
343: correctly by build.sh. Manual builds have to update /usr/share/mk
344: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 345:
1.217 jruoho 346: 20101217:
347: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 348: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 349: group(5) in order to make the program work with existing setups.
350:
1.216 christos 351: 20101125:
352: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 353: variables with names that contain '='. Revision 1.18 of env.c
354: assumed that this was allowed. Installing a new libc with an
1.216 christos 355: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
356: break which affects the autoconf tests for dependency finding,
357: so building gcc will end up printing:
358: checking dependency style of gcc... none
359: configure: error: no usable dependency style found
360: Fix it by rebuilding and re-installing env.
1.138 lukem 361:
1.215 mrg 362: 20101119:
363: Recent Xorg updates in xsrc/external/mit/ may cause various build
364: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
365: have any build problems with xsrc, or problems with mismatched
366: versions between xorg-server and drivers.
367:
1.213 jmmv 368: 20100604:
369: The update of ATF to 0.9 causes old tests written in shell to fail
370: unless they are rebuilt. If you are building with MKUPDATE=yes,
371: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
372: trees by hand.
373:
1.211 tnozaki 374: 20100522:
1.212 mrg 375: Recent Xorg updates in xsrc/external/mit/ will cause various build
376: problems. Delete your entire DESTDIR and OBJDIR if you have any
377: build problems with xsrc.
378:
379: 20100522:
1.211 tnozaki 380: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 381: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 382:
1.210 christos 383: 20100520:
1.241 wiz 384: The location of the xkb compiled descriptions has changed. Please
1.210 christos 385: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
386:
1.209 njoly 387: 20100222:
388: The shared objects file extension has been changed from .so to
389: .pico, in order to avoid conflicts with shared libraries names
390: libXX.so. All now stale regular .so files can be removed from
391: your object directories.
392:
1.208 roy 393: 20100204:
394: The termcap database has been removed from the sources,
395: but has not been marked obsolete so it is not removed
396: from the system when upgrading.
397: As such, you will need to remove them from your object
398: and destination directories.
399:
1.203 dyoung 400: 20091101:
1.205 dholland 401: After updating, it may be necessary to make the 'cleandir'
402: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
403: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
404: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 405:
1.202 mrg 406: 20091001:
1.206 dholland 407: On amd64 you must rebuild tools (to get the new binutils)
408: before building a kernel, or the build fails on cpufunc.S.
409:
410: 20091001:
1.202 mrg 411: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
412: symlink, failing the build. Delete the link, and the subdir
413: it is in, and retry your build.
414:

1.195 perry 432: 20090501:
433: Several new functions were added to string.h/libc, and this
434: can cause autoconf problems during the tool build for people
1.241 wiz 435: who fail to clean out their tools objects properly. If you
1.195 perry 436: note messages about stpcpy, stpncpy or strnlen accompanying a

438: objects and start again.
439:
1.194 mrg 440: 20090325:

1.241 wiz 445: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 446: need to 'rm -f __posix_fadvise50.*' in the libc build directory

1.192 skrll 448:
1.191 joerg 449: 20090202:

453:
1.184 christos 454: 20090110:
1.241 wiz 455: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
456: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 457: This is needed even in the MODULAR kernel because there is
458: conditionally compiled code in rtsock.c.
1.184 christos 459: 2. make sure build.sh completes and the binaries in a chroot work
460: before installing.
461: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 462: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 463: are installed properly, and start building libraries first libc
464: and libutil, install them and then continue building all the
1.241 wiz 465: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 466: the new libraries are installed, you can restart the build.
467: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 468: rebuild the required packages to update their shared libraries.
469: Any package you rebuild will require rebuilding all the packages
470: that depend on it.
1.186 christos 471: 5. Next time you run pwd_mkdb with the new binary, the file
472: will be upgraded and it will not be backwards compatible.
1.190 apb 473: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
474: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 475: for utmp. You are better off removing the old files after
1.190 apb 476: upgrading. The automated clearing of /var/run during
477: boot, and the automated rotating of files in /var/log by
478: newsyslog(8), may mean that you do not have to remove the
479: files manually.
480: 7. The optional accounting file (/var/account/acct, see
481: accton(8)) has not been versioned, and will need to be
482: removed. The automatic rotation of the accounting file by
483: /etc/daily limits the bad consequences of failure to remove
484: the file.
1.196 dholland 485: 8. Application software that writes time_t to binary files on
1.241 wiz 486: disk will break or need attention. Most notably: if you are
1.196 dholland 487: using PostgreSQL < 8.4, you need to dump your databases,
488: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 489:
1.183 pgoyette 490: 20081219:
491: config(1) has been updated, and one of the files it creates -
492: swapnetbsd.o - has changed format. You need to rebuild config
493: (done automatically by build.sh) and then you need to rerun
494: config on all kernel configuration files before rebuilding those
495: kernels.
496:
1.181 cube 497: 20081205:
498: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
499: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
500: set and will appear as extra files for MKX11=no update builds.

1.182 tsutsui 503: On i386, various kernel options(4) in GENERIC including
1.180 wiz 504: file systems have been disabled and moved into kernel modules.
505: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 506: following files as well as a new GENERIC kernel:
507:
508: - build and install kernel modules from src/sys/modules
509:
510: - install the latest bootloader, which will load a module
1.180 wiz 511: for the file system from which the kernel is loaded automatically
1.179 tsutsui 512:
1.180 wiz 513: If you have to load your kernel from a file system which is not of
514: the same type as the root file system, you have to load the necessary
515: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 516:
1.178 lukem 517: 20080827:
518: If you built and installed a libc from sources between
519: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
520: which results in false errors reported by lint(1).
521: Since this breaks the libc build itself, manual help is
1.180 wiz 522: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 523: $ (cd lib/libc && make MKLINT=no dependall install)
524:
1.177 christos 525: 20080813:
526: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 527: about .go files. You need to remove all .depend files and rebuild.

1.200 dholland 529: 20080802:
530: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 531: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 532: for -current.
533:
534: Threaded programs (using libpthread) and C++ programs (using
535: libstdc++) compiled after 20070907 and before 20080802 need to
536: be recompiled.
537:

547: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 548: especially an uncleanly mounted journaled filesystem. WAPBL

1.241 wiz 557: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
558: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 559: utility needs to be rebuilt and reinstalled as older binaries

610: enumerate interfaces was fixed. The bug began to cause
611: problems after 20070911 when the kernel's SIOCGIFCONF
612: implementation was repaired. From 20070529 to 20070911 racoon

1.241 wiz 619: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It

1.161 dsl 624: 20070422:
625: The way OS emulations lookup filenames inside the emulation root
626: has been changed. Rather than modify the pathname (and copy back
627: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 628: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 629: root file system will be relative to that file system - unless they
1.161 dsl 630: start /../ this is useful when the emulated root is a real install

656: The threading model was changed when the newlock2 branch
657: was merged to NetBSD-current. If you boot with a new
658: kernel (version 4.99.10), then you also need a new pthread
659: library (/usr/lib/libpthread.so.0.7). If you boot with

1.1 abs 704: Hints for a more successful build:
705: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 706: Use build.sh, but do not use its "expert mode":
1.132 jmmv 707: This will automatically build the tools in the
1.123 jmc 708: correct order, and it will keep the tools and the
709: new build products from interfering with the running
710: system. This will allow you to ignore most of the
711: other advice in this file.
1.2 mrg 712: Build a new kernel first:
713: This makes sure that any new system calls or features
714: expected by the new userland will be present. This
715: helps to avoid critical errors when upgrading.
1.1 abs 716: Use object directories:
717: This helps to keep stale object
718: files from polluting the build if a Makefile "forgets"
719: about one. It also makes it easier to clean up after
720: a build. It's also necessary if you want to use the
721: same source tree for multiple machines.
1.123 jmc 722: To use object directories with build.sh:
723: a) invoke build.sh with the "-M" or "-O" options.
724: To use object directories without using build.sh:
1.1 abs 725: a) cd /usr/src ; make cleandir
1.2 mrg 726: b) Add "OBJMACHINE=yes" to /etc/mk.conf
727: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 728: d) cd /usr/src ; make build
1.2 mrg 729: Note that running "make obj" in a directory will create
730: in obj.$MACHINE directory.
1.1 abs 731: Build to a DESTDIR:
1.123 jmc 732: This helps to keep old installed files (especially libraries)
733: from interfering with the new build.
734: To build to a DESTDIR with build.sh, use the "-D" option.
735: To build to a DESTDIR without using build.sh, set the DESTDIR
736: environment variable before running make build. It should be
737: set to the pathname of an initially empty directory.
738: Problems: if you do not use build.sh, you might need to
739: update critical utilities without using DESTDIR since
740: nothing is executed from what is installed in DESTDIR.
741: (See critical utils, below.)
1.1 abs 742: Build often:
743: This keeps critical utilities current enough to not choke
744: on any other part of the source tree that depends on up to

756:
757: Failsafe rebuild of a small part of the tree:
758: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
759: To make sure you rebuild something correctly you want to do
760: something like the following:
761: 1) Make sure the includes and .mk files are up to date.
762: 2) Make sure any program used to build the particular
763: utility is up to date. (yacc, lex, etc...)

768: make obj
769: make depend && make

863: Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
864: No such file or directory.
865: Cause: If a directory is created by mistake, then it is sometimes
866: deleted from the CVS repository using administrative commands
867: that bypass the normal cvs access controls. If your cvs working tree
868: contains references to a directory that has been deleted on the
869: server in this way, then "cvs update" reports this error.
870: Fix: Recursively delete the affected directory from your working tree
871: and try the update again.
