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:
1.309 ! christos 22: 20200614:
! 23: blacklist* has been renamed to blocklist*. You need to manually:
! 24: mv /var/db/bl{a,o}cklist.db
! 25: fix npf rules that mention blacklist
! 26: fix rc.conf variables
! 27:
1.308 christos 28: 20200601:
29: Due to a mistake in LIBISPRIVATE handling, .so libraries were
30: created in the build directories and need cleaning.
31:
1.307 mrg 32: 20200311:
33: GCC 8 ports will need cleaning in src/tools/gcc and
34: src/external/gpl3/gcc due to GCC 8.4 update.
35:
1.306 christos 36: 20191118:
37: More architectures were switched to gcc8:
38: i386, ia64 powerpc64, sparc, sparc64, arm
39: The same comments as in 20191022 apply.
40:
1.305 martin 41: 20191112:
42: The LLVM update requires a clean rebuild for all architectures using
43: LLVM during the tools build phase (i386, amd64, aarch64).
44:
1.304 martin 45: 20191022:
46: Ports amd64 and aarch64 switched to GCC 8.3 by default.
47: In-place ("expert mode", build.sh -E) builds are not supported
48: when going from a GCC 7 userland to GCC 8. Do a regular
49: build to a different DESTDIR (or preferably: build.sh -U) at least
1.306 christos 50: once and install sets, or download comp.{tar.xz,tgz} from the
1.304 martin 51: daily builds and install that before doing the next in-place build.
52:
1.303 mrg 53: 20191001:
54: GCC 8.3 was imported. Builds of src/tools/gcc may fail if
55: old builds with GCC 7 output now uses GCC 8. Clean this
56: directory, and also clean src/external/gpl3/gcc.
57:
1.302 riastrad 58: 20190903:
1.306 christos 59: Files with names that coincide with existing files' names on
1.302 riastrad 60: case-insensitive file systems were inadvertently committed, for
61: radeon GPU firmware. We cannot mark these as obsolete for
62: postinstall to fix, so if you updated src since 2019-08-26, and
63: ran build.sh distribution or ran build.sh release, you must
64: manually delete the following files in your DESTDIR (which is
65: usually $OBJDIR/destir.$ARCH), or from / if you have installed
66: them:

136: later.
137:
1.301 martin 138: 20190727:
139: The uefi bootloader has gained tftp support and needs a clean
140: build. If you do update builds, manually clean its object
141: directory by something like:
142: cd sys/arch/i386/stand/efiboot && make clean
143:
1.300 martin 144: 20190723:
145: The jemalloc allocator in libc is now build without extended
146: debugging (for performance reasons). In update builds make sure
147: to rebuild it completly, by removing all affected object files,
148: including compat builds, something like:
149: cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
150:
1.299 mrg 151: 20190207:
152: GCC 7 switched for many ports. Update builds are likely to fail.
153:
1.298 martin 154: 20180924:
155: A newer OpenSSL version has been imported. If you are doing
156: update builds, make sure to remove all old obj dirs, like:
157: cd /usr/obj && find . -type d -name openssl | xargs rm -rf
158:
1.297 joerg 159: 20180717:
160: On aarch64 int64_t and related types have changed from long long
161: to long. This requires recompiling all C++ binaries.
162:
1.296 martin 163: 20180713:
164: On amd64 and i386 static binaries are now build position
165: independend. This requires recompilation of all object
166: files used to create the crunched /rescue binary.
167: Clean the rescue directory in your obj directory before
168: doing an update build, otherwise linking will fail.
169:
1.293 jakllsch 170: 20180414:
171: Existing binutils was migrated to binutils.old. Manual
172: removal of tools/binutils objects directory may be required
173: to fix tools build failure.
174:
1.292 mrg 175: 20180311:
176: bdftopcf was updated and may need cleaning in the
177: src/external/mit/xorg/tools/bdftopcf subdirectory if there are
178: link errors.
179:
1.291 mrg 180: 20180212:
181: between OpenSSL and GCC updates, many things may fail to build.
182: any failure that looks like GCC or openssl is best handled by
183: a clean destdir and objdir. Full cleandir and destdir deletion
184: is recommended if build failures occur.
185:
1.288 martin 186: 20171225:
187: removal of the vadvise syscall requires manual removal of all
188: associated files from the libc build object directory (including
1.289 christos 189: the .depend files) - a command like:
1.288 martin 190: cd $OBJ && find . -type d -name libc | xargs rm -rf
1.289 christos 191: For architectures that support multiple "compat" binary targets,
192: you'll need to cleanup both the regular libc directory and the
1.290 martin 193: compat ones (the above command will do that).
1.288 martin 194:
1.287 kre 195: 20171010:
196: a change to the build structure of external/bsd/acpica/bin/iasl
197: means that its objdir (or *.d and .depend at least) might need
198: to be manually removed - or a build done once without -u.
199:
1.286 mrg 200: 20170822:
201: a new version of GMP has been imported and probably
202: will break parts of builds related to themselves or GCC, both
203: in the tools and the native section. Remove all GCC, GMP, MPFR
204: and MPC objdirs or build once without -u.
205:
1.285 mrg 206: 20170816:
207: a new version of MPFR and MPC have been imported and probably
208: will break parts of builds related to themselves or GCC, both
209: in the tools and the native section. Remove all GCC, GMP, MPFR
210: and MPC objdirs or build once without -u.
211:
1.284 martin 212: 20170402:
213: a new version of dhcpcd has been imported, which does not support
214: update builds from the previous version. Remove your
215: external/bsd/dhcpcd object dir or build once without -u.
216:
1.281 roy 217: 20170211:
218: a new terminfo database has been imported.
219: The structure of it has changed slightly from prior versions and
220: an updated tic tool is required.
221: If you build.sh, don't use -u
222:
1.280 kre 223: 20170207:
1.278 kre 224: various arch dependent libc/exect.S files were removed
1.279 kre 225: Either remove the obj directories (lib/libc and compat/amd64/i386/lib
226: if it exists) or do a clean build.
227: (This is a bug in the make system, it should be corrected without
228: human intervention, but isn't.)
1.278 kre 229:
1.277 martin 230: 20170104:
231: xinput build options have changed.
232: Remove the obj directory (external/mit/xorg/bin/xinput)
233: if you build.sh -u
234:
1.276 martin 235: 20170103:
236: a new version of flex has been imported.
237: Remove the file from obj (external/bsd/flex)
238: if you build.sh -u
239:
1.275 spz 240: 20161014:
241: a new version of OpenSSL has been imported.
242: Remove the files from obj (crypto/external/bsd/openssl)
243: if you build.sh -u
244:
1.274 martin 245: 20161009:
246: a new version of dhcpcd has been imported with slightly changed
247: build infrastructure. When doing a build.sh -u this requires
248: pruning the external/bsd/dhcpcd objdir.
249:
1.273 mrg 250: 20160914:
251: i386, amd64, shark, ofppc and macppc have joined shark and x68k
252: ports in using xorg-server 1.18. This requires a clean destdir
253: and a clean objdir.
254:
1.272 dholland 255: 20160527:
256: i386 needs a full cleandir or objdir deletion because PIE has
257: been enabled. (see the amd64 entry two down for further info)
258:
1.270 christos 259: 20160418:
260: libedit needs manual removal of all autogenerated files since
1.271 christos 261: some of them are not autogenerated anymore. Remember that there
262: might be two copies of libedit if your platform builds "compat".
1.270 christos 263:
1.268 riastrad 264: 20160410:
265: amd64 needs full "make cleandir" or deletion of objdir now that
266: PIE has been enabled for amd64. PIE, or position-independent
267: executables, means all code, including executables and not just
268: shared libraries, is position-independent and hence able to be
269: relocated by ASLR, address space layout randomization.
270:
271: The change was made in Makefile variables for compiler and
272: linker flags, for which make(1) does not record dependencies,
273: hence it is unable to detect that all .o files need rebuilding.
274:
275: Partial rebuilds with some modified source files will likely
276: fail when linking executables, since the linker refuses to mix
277: position-independent code with position-dependent code in
278: position-independent executables:
279:
280: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
281:
1.267 mrg 282: 20160401:
283: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 284: Some people have found that cleandir is not sufficient, so if
285: in doubt delete the entire object directory tree for gcc.
1.267 mrg 286:
1.266 aymeric 287: 20160306:
1.265 aymeric 288: NetBSD's regexp implementation is now part of libnbcompat.
289: Nblex, nbm4, nbpax, nbsed use it and they may crash on
290: non-NetBSD hosts if linked with stale object files produced
291: while they included a non-NetBSD regex.h.
292: In any case, you should "make cleandir" at least these tools
293: before updating your toolchain.
294:
1.264 martin 295: 20160125:
296: Dtrace has been enabled by default on some architectures.
297: When doing an update build, make sure to clean the etc/mtree
298: object directory before starting the build - otherwise the
299: needed directories in destdir will not be created.
300: An easy way to do this is:
301: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
302:
1.263 dholland 303: 20150818:
304: New acpica requires "make cleandir" in src/external/bsd/acpica
305: again.
306:
1.262 christos 307: 20150413:
308: New acpica requires "make cleandir" and reinstalling yacc
309: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
310: also "make cleandir" in /usr/src/external/bsd/acpica.
311:
1.261 martin 312: 20150404:
313: Lint changes require a full rebuild of the tool, so make
314: sure to build without -u option to build.sh, or manually
315: do a make cleandir in src/tools/lint1 and
316: src/usr.bin/xlint.
317:
1.260 skrll 318: 20150310:
319: Improvements to openssl for arm mean that update builds of
320: the openssl libraries will fail. A make cleandir in
321: external/bsd/openssl/lib is needed
322:
1.258 martin 323: 20141026:
1.259 msaitoh 324: A mishap during the import of pppd may cause your corruption
1.258 martin 325: in your cvs directory if you happened to do a cvs update
326: during a short period of time. To fix, just remove the
327: directory src/external/bsd/ppp/dist/pppd completely
328: and let cvs restore it on next update.
329:
1.256 apb 330: 20140721:
331: The src/external/mit/lua/src directory was accidentally created
332: and then deleted in the CVS repository. If you get errors like
333:
334: cvs [update aborted]: cannot open directory
335: /cvsroot/src/external/mit/lua/src: No such file or directory
336:
337: then delete your local copy of that directory tree and try again.
338:
1.255 joerg 339: 20140530:
340: ARM eABI switched to DWARF based exception handling. This requires
341: rebuilding all C++ code. It is strongly advised to do a clean build.
342:
1.251 martin 343: 20140131:
1.253 joerg 344: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 345: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 346: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 347:
1.250 christos 348: 20131227:
349: 1. The new ntpd runs in a restricted mode to prevent amplification
350: attacks. If you need ntpdc to work you need to explicitly enable
351: mode7 in your config file. Make sure you put the necessary restrict
352: statements to avoid being exposed.
353: 2. strncat has moved from lib/libc to common/lib/libc; you might need
354: to make clean in libc
355:
1.249 mrg 356: 20131129:
357: The GMP sources were updated, and builds will likely fail without
358: cleaning their build trees for both tools and in-tree, like below.
359:
1.248 mrg 360: 20131128:
361: The MPC and MPFR sources were updated, and builds may require their
362: tools and in-tree directories cleaned for successful updates.
363:
1.246 martin 364: 20130605:
1.247 spz 365: The kernel option FAST_IPSEC no longer exists, it's been renamed
366: to IPSEC (and the older IPSEC version removed).
367:
368: 20130605:
1.246 martin 369: Previous freetype installations eroneously installed private
370: header files. If you are building against a non-empty $DESTDIR,
371: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
372:
1.245 mrg 373: 20130531:
374: The xdm update may cause build failure due to xdm.man being
375: in the obj tree. Make sure to ensure any like this:
376: nbmake: nbmake: don't know how to make xdm.man. Stop
377: is fixed by deleting the xdm.man in the obj tree.
378:
1.244 mrg 379: 20130530:
380: Updates of many xsrc packages will leave old .pc files around.
381: Best to clean out the xsrc objdir entirely before rebuilds.
382:
1.242 christos 383: 20130301:
384: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 385: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 386:
1.238 dholland 387: 20120726:
1.241 wiz 388: The update of OpenSSL requires cleaning both the OpenSSL build
389: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 390: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 391: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 392: cause third-party software to link incorrectly and/or crash.
1.238 dholland 393:
1.237 wiz 394: 20120507:
1.241 wiz 395: The database schema for makemandb was changed. You will
1.237 wiz 396: need to update the database using 'makemandb -f' or wait
397: for the next weekly run to fix it.
398:
1.236 bsh 399: 20120319:
400: sys/conf/Makefile.kern.inc has been modified to adjust the
401: size of db_symtab automatically. You need to update dbsym in
402: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
403: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
404: mk.conf.
405:
1.235 joerg 406: 20120216:
1.241 wiz 407: Default for MKCATPAGES changed to NO. Update builds will fail
408: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 409: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 410: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 411: the next run of weekly will fix it.
1.233 joerg 412:
1.232 christos 413: 20111227:
414: If you built between 20111225 and 20111227 you need to remove
415: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the

417:
1.231 tls 418: 20111125:
419: The "rnd" pseudodevice has been added to sys/conf/std, which
420: means it should no longer be explicitly listed in kernel
421: configuration files. The line "pseudo-device rnd" should be
422: removed from any custom kernel config files users may have.
423:
1.230 tls 424: 20111119:
425: A problem with the datastructures used by the rndctl(8)
426: utility (pointers in datastructures in an array, making 32->64
427: bit compatibility very painful) has been fixed in a
428: non-backwards-compatible way. If you replace your kernel,
429: replace your rndctl executable too.
1.241 wiz 430:
1.229 jym 431: 20111001:
432: the prop_*_send_syscall() functions from proplib(3) have been
433: changed and their new version is not backward compatible with the old
1.241 wiz 434: one. So ensure that all consumers of these functions (currently:
1.229 jym 435: quota2 code and its tests) are updated together with the new lib.
436:
1.228 mrg 437: 20110817:
438: sparc has been changed to use GCC 4.5.3, so any objdir or
439: DESTDIR for them should be deleted before updating.
440:
1.227 riastrad 441: 20110806:
442: i386 and amd64 have been changed to use GCC 4.5.3, so any
443: objdir or DESTDIR for them should be deleted before updating.
444:
1.226 mrg 445: 20110805:
446: The update to GCC 4.5.3 requires a non-trivial portion of
447: the tree to be cleaned. Best to delete both objdir and
448: DESTDIR before running this update. So far, only the
449: sparc64, mips and powerpc platforms have changed.
450:
1.225 matt 451: 20110803:
1.241 wiz 452: The layout of external/public-domain/xz has changed. To do an
1.225 matt 453: update build you will have to remove the contents of the OBJDIR
454: for external/public-domain/xz/bin by hand as the xz entry there
455: is now a directory.
456:
1.223 joerg 457: 20110410:
1.241 wiz 458: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 459: update build you have to clean both tools/binutils and
460: tools/gcc by hand.
1.223 joerg 461:
1.222 plunky 462: 20110328:
463: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 464: ordering issues with "make all". It may be necessary to remove
1.222 plunky 465: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
466: if your update build fails, as the "Xorg" entry there is now a
467: directory.
468:
1.220 joerg 469: 20110121:
1.221 lukem 470: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 471: the build of individual parts of the tree. This is handled
472: correctly by build.sh. Manual builds have to update /usr/share/mk
473: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 474:
1.217 jruoho 475: 20101217:
476: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 477: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 478: group(5) in order to make the program work with existing setups.
479:
1.216 christos 480: 20101125:
481: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 482: variables with names that contain '='. Revision 1.18 of env.c
483: assumed that this was allowed. Installing a new libc with an
1.216 christos 484: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
485: break which affects the autoconf tests for dependency finding,
486: so building gcc will end up printing:
487: checking dependency style of gcc... none
488: configure: error: no usable dependency style found
489: Fix it by rebuilding and re-installing env.
1.138 lukem 490:
1.215 mrg 491: 20101119:

493: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
494: have any build problems with xsrc, or problems with mismatched
495: versions between xorg-server and drivers.

1.213 jmmv 497: 20100604:
498: The update of ATF to 0.9 causes old tests written in shell to fail
499: unless they are rebuilt. If you are building with MKUPDATE=yes,
500: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
501: trees by hand.

1.211 tnozaki 503: 20100522:
1.212 mrg 504: Recent Xorg updates in xsrc/external/mit/ will cause various build

506: build problems with xsrc.
507:
508: 20100522:
1.211 tnozaki 509: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 510: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 511:
1.210 christos 512: 20100520:
1.241 wiz 513: The location of the xkb compiled descriptions has changed. Please
1.210 christos 514: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
515:
1.209 njoly 516: 20100222:
517: The shared objects file extension has been changed from .so to
518: .pico, in order to avoid conflicts with shared libraries names
519: libXX.so. All now stale regular .so files can be removed from
520: your object directories.
521:
1.208 roy 522: 20100204:
523: The termcap database has been removed from the sources,
524: but has not been marked obsolete so it is not removed
525: from the system when upgrading.
526: As such, you will need to remove them from your object
527: and destination directories.
528:
1.203 dyoung 529: 20091101:
1.205 dholland 530: After updating, it may be necessary to make the 'cleandir'
531: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
532: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
533: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 534:
1.202 mrg 535: 20091001:
1.206 dholland 536: On amd64 you must rebuild tools (to get the new binutils)
537: before building a kernel, or the build fails on cpufunc.S.
538:
539: 20091001:
1.202 mrg 540: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
541: symlink, failing the build. Delete the link, and the subdir
542: it is in, and retry your build.
543:
1.201 dsl 544: 20090718:
545: libc build changed so that strchr() provides the extra entry
1.241 wiz 546: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 547: may fail because the archive contains the unwanted index.o.
548: (Similarly for strrchr() and rindex().)
549:
1.198 mrg 550: 20090709:
551: Native Xorg was upgraded again. Builds will probably fail again
552: without a clean objdir, at least for src/external/mit/xorg.
553:
1.197 mrg 554: 20090616:
555: Native Xorg was upgraded. Builds will need a clean objdir for
556: src/external/mit/xorg. Upgrading a system from sets will not
557: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
558: subdirectory has been changed into a file, and this needs to
559: be manually "rm -r"'ed before installing xbase.tgz.
560:
1.195 perry 561: 20090501:
562: Several new functions were added to string.h/libc, and this
563: can cause autoconf problems during the tool build for people
1.241 wiz 564: who fail to clean out their tools objects properly. If you
1.195 perry 565: note messages about stpcpy, stpncpy or strnlen accompanying a
566: failure during the tool build, clean out all your tools
567: objects and start again.
568:
1.194 mrg 569: 20090325:
570: The i386 port was switched to i486 default toolchain. This requires
571: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
572:
1.192 skrll 573: 20090126:
1.241 wiz 574: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 575: need to 'rm -f __posix_fadvise50.*' in the libc build directory
576: to avoid using the old assembly stub.
1.192 skrll 577:
1.191 joerg 578: 20090202:
579: pkg_install now depends on the pkgdb cache for automatic conflict
580: detection. It is recommented to rebuild the cache with
581: ``pkg_admin rebuild''.
582:
1.184 christos 583: 20090110:
1.241 wiz 584: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
585: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 586: This is needed even in the MODULAR kernel because there is
587: conditionally compiled code in rtsock.c.
1.184 christos 588: 2. make sure build.sh completes and the binaries in a chroot work
589: before installing.
590: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 591: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 592: are installed properly, and start building libraries first libc
593: and libutil, install them and then continue building all the
1.241 wiz 594: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 595: the new libraries are installed, you can restart the build.
596: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 597: rebuild the required packages to update their shared libraries.
598: Any package you rebuild will require rebuilding all the packages
599: that depend on it.
1.186 christos 600: 5. Next time you run pwd_mkdb with the new binary, the file
601: will be upgraded and it will not be backwards compatible.
1.190 apb 602: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
603: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 604: for utmp. You are better off removing the old files after
1.190 apb 605: upgrading. The automated clearing of /var/run during
606: boot, and the automated rotating of files in /var/log by
607: newsyslog(8), may mean that you do not have to remove the
608: files manually.
609: 7. The optional accounting file (/var/account/acct, see
610: accton(8)) has not been versioned, and will need to be
611: removed. The automatic rotation of the accounting file by
612: /etc/daily limits the bad consequences of failure to remove
613: the file.
1.196 dholland 614: 8. Application software that writes time_t to binary files on
1.241 wiz 615: disk will break or need attention. Most notably: if you are
1.196 dholland 616: using PostgreSQL < 8.4, you need to dump your databases,
617: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 618:
1.183 pgoyette 619: 20081219:
620: config(1) has been updated, and one of the files it creates -
621: swapnetbsd.o - has changed format. You need to rebuild config
622: (done automatically by build.sh) and then you need to rerun
623: config on all kernel configuration files before rebuilding those
624: kernels.
625:
1.181 cube 626: 20081205:
627: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
628: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
629: set and will appear as extra files for MKX11=no update builds.

1.182 tsutsui 632: On i386, various kernel options(4) in GENERIC including
1.180 wiz 633: file systems have been disabled and moved into kernel modules.
634: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 635: following files as well as a new GENERIC kernel:
636:
637: - build and install kernel modules from src/sys/modules
638:
639: - install the latest bootloader, which will load a module
1.180 wiz 640: for the file system from which the kernel is loaded automatically
1.179 tsutsui 641:
1.180 wiz 642: If you have to load your kernel from a file system which is not of
643: the same type as the root file system, you have to load the necessary
644: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 645:
1.178 lukem 646: 20080827:
647: If you built and installed a libc from sources between
648: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
649: which results in false errors reported by lint(1).
650: Since this breaks the libc build itself, manual help is
1.180 wiz 651: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 652: $ (cd lib/libc && make MKLINT=no dependall install)
653:
1.177 christos 654: 20080813:
655: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 656: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 657:
1.200 dholland 658: 20080802:
659: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 660: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 661: for -current.
662:
663: Threaded programs (using libpthread) and C++ programs (using
664: libstdc++) compiled after 20070907 and before 20080802 need to
665: be recompiled.
666:
667: One way to find affected pkgsrc packages:
668:

673: WAPBL (metadata journaling support) has been added, but at this
674: time isn't backwards compatible with pre-WAPBL aware kernels
675: and userland (fsck_ffs in particular). Please make sure you
676: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 677: especially an uncleanly mounted journaled filesystem. WAPBL
678: also requires the super block to be in the UFS2 format. You
679: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 680:

1.173 freza 685: 20080531:
1.241 wiz 686: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
687: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 688: utility needs to be rebuilt and reinstalled as older binaries

1.164 gdt 737: 20070913:
738: A latent bug in dhclient/dhcpd that caused it to be unable to
739: enumerate interfaces was fixed. The bug began to cause
740: problems after 20070911 when the kernel's SIOCGIFCONF
741: implementation was repaired. From 20070529 to 20070911 racoon
742: could not enumerate interfaces. (These are noted because
743: normal kernel/userspace version matching hygiene is not
744: sufficient to avoid this problem.) Ensure that both kernel

1.161 dsl 753: 20070422:
754: The way OS emulations lookup filenames inside the emulation root
755: has been changed. Rather than modify the pathname (and copy back
756: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 757: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 758: root file system will be relative to that file system - unless they
1.161 dsl 759: start /../ this is useful when the emulated root is a real install

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

807: The configure script used in the src/tools/gcc compiler has been
808: changed to indicate that our libc has ssp support built-in and
1.241 wiz 809: does not depend on -lssp and -lssp-nonshared. You'll need to

817: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
818: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
819: kernel configuration for an example. X servers from the last

828: socket(2) has changed, and its system call has been versioned.

1.1 abs 833: Hints for a more successful build:
834: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 835: Use build.sh, but do not use its "expert mode":
1.132 jmmv 836: This will automatically build the tools in the
1.123 jmc 837: correct order, and it will keep the tools and the
838: new build products from interfering with the running
839: system. This will allow you to ignore most of the
840: other advice in this file.
1.2 mrg 841: Build a new kernel first:
842: This makes sure that any new system calls or features
843: expected by the new userland will be present. This
844: helps to avoid critical errors when upgrading.
1.1 abs 845: Use object directories:
846: This helps to keep stale object
847: files from polluting the build if a Makefile "forgets"
848: about one. It also makes it easier to clean up after
849: a build. It's also necessary if you want to use the
850: same source tree for multiple machines.
1.123 jmc 851: To use object directories with build.sh:
852: a) invoke build.sh with the "-M" or "-O" options.
853: To use object directories without using build.sh:
1.1 abs 854: a) cd /usr/src ; make cleandir
1.2 mrg 855: b) Add "OBJMACHINE=yes" to /etc/mk.conf
856: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 857: d) cd /usr/src ; make build
1.2 mrg 858: Note that running "make obj" in a directory will create
859: in obj.$MACHINE directory.
1.1 abs 860: Build to a DESTDIR:
1.123 jmc 861: This helps to keep old installed files (especially libraries)
862: from interfering with the new build.
863: To build to a DESTDIR with build.sh, use the "-D" option.
864: To build to a DESTDIR without using build.sh, set the DESTDIR
865: environment variable before running make build. It should be
866: set to the pathname of an initially empty directory.
867: Problems: if you do not use build.sh, you might need to
868: update critical utilities without using DESTDIR since
869: nothing is executed from what is installed in DESTDIR.
870: (See critical utils, below.)
1.1 abs 871: Build often:
872: This keeps critical utilities current enough to not choke
873: on any other part of the source tree that depends on up to
1.123 jmc 874: date functionality. If you use build.sh, you should not have
875: this problem.

1.1 abs 877: What to do if things don't work:
878: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 879: When things don't work there are usually a few things that commonly
1.1 abs 880: should be done.
881: 1) make includes
882: This should be done automatically by make build.
883: 2) cd share/mk && make install
884: Again, automatically done by make build.
885:
886: Failsafe rebuild of a small part of the tree:
887: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
888: To make sure you rebuild something correctly you want to do
889: something like the following:
890: 1) Make sure the includes and .mk files are up to date.
891: 2) Make sure any program used to build the particular
892: utility is up to date. (yacc, lex, etc...)
893: 3) cd ...path/to/util...
894: make cleandir
895: rm ...all obj directories...
896: make cleandir # yes, again
897: make obj
898: make depend && make
899:
900: Failsafe rebuild of the entire tree:
901: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
902: If you really want to make sure the source tree is clean and
1.2 mrg 903: ready for a build try the following. Note that sourcing /etc/mk.conf
904: (a make(1) Makefile) in this manner is not right, and will not work
905: for anyone who uses any make(1) features in /etc/mk.conf.

997: contains references to a directory that has been deleted on the
