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:
1.311 ! mrg 22: 20200811:
! 23: GCC updates may require cleaning the objdir.
! 24:
1.309 christos 25: 20200614:
1.310 christos 26: blacklist* has been renamed to blocklist*. postinstall(8)
27: should handle the migration
1.309 christos 28:
1.308 christos 29: 20200601:
30: Due to a mistake in LIBISPRIVATE handling, .so libraries were
31: created in the build directories and need cleaning.
32:
1.307 mrg 33: 20200311:
34: GCC 8 ports will need cleaning in src/tools/gcc and
35: src/external/gpl3/gcc due to GCC 8.4 update.
36:
1.306 christos 37: 20191118:
38: More architectures were switched to gcc8:
39: i386, ia64 powerpc64, sparc, sparc64, arm
40: The same comments as in 20191022 apply.
41:
1.305 martin 42: 20191112:
43: The LLVM update requires a clean rebuild for all architectures using
44: LLVM during the tools build phase (i386, amd64, aarch64).
45:
1.304 martin 46: 20191022:
47: Ports amd64 and aarch64 switched to GCC 8.3 by default.
48: In-place ("expert mode", build.sh -E) builds are not supported
49: when going from a GCC 7 userland to GCC 8. Do a regular
50: build to a different DESTDIR (or preferably: build.sh -U) at least
1.306 christos 51: once and install sets, or download comp.{tar.xz,tgz} from the
1.304 martin 52: daily builds and install that before doing the next in-place build.
53:
1.303 mrg 54: 20191001:
55: GCC 8.3 was imported. Builds of src/tools/gcc may fail if
56: old builds with GCC 7 output now uses GCC 8. Clean this
57: directory, and also clean src/external/gpl3/gcc.
58:
1.302 riastrad 59: 20190903:
1.306 christos 60: Files with names that coincide with existing files' names on
1.302 riastrad 61: case-insensitive file systems were inadvertently committed, for
62: radeon GPU firmware. We cannot mark these as obsolete for
63: postinstall to fix, so if you updated src since 2019-08-26, and
64: ran build.sh distribution or ran build.sh release, you must
65: manually delete the following files in your DESTDIR (which is
66: usually $OBJDIR/destir.$ARCH), or from / if you have installed
67: them:

136: We will re-import these radeon firmware images another way
137: later.
138:
1.301 martin 139: 20190727:
140: The uefi bootloader has gained tftp support and needs a clean
141: build. If you do update builds, manually clean its object
142: directory by something like:
143: cd sys/arch/i386/stand/efiboot && make clean
144:
1.300 martin 145: 20190723:
146: The jemalloc allocator in libc is now build without extended
147: debugging (for performance reasons). In update builds make sure
148: to rebuild it completly, by removing all affected object files,
149: including compat builds, something like:
150: cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
151:
1.299 mrg 152: 20190207:
153: GCC 7 switched for many ports. Update builds are likely to fail.
154:
1.298 martin 155: 20180924:
156: A newer OpenSSL version has been imported. If you are doing
157: update builds, make sure to remove all old obj dirs, like:
158: cd /usr/obj && find . -type d -name openssl | xargs rm -rf
159:
1.297 joerg 160: 20180717:
161: On aarch64 int64_t and related types have changed from long long
162: to long. This requires recompiling all C++ binaries.
163:
1.296 martin 164: 20180713:
165: On amd64 and i386 static binaries are now build position
166: independend. This requires recompilation of all object
167: files used to create the crunched /rescue binary.
168: Clean the rescue directory in your obj directory before
169: doing an update build, otherwise linking will fail.
170:
1.293 jakllsch 171: 20180414:
172: Existing binutils was migrated to binutils.old. Manual
173: removal of tools/binutils objects directory may be required
174: to fix tools build failure.
175:
1.292 mrg 176: 20180311:
177: bdftopcf was updated and may need cleaning in the
178: src/external/mit/xorg/tools/bdftopcf subdirectory if there are
179: link errors.
180:
1.291 mrg 181: 20180212:
182: between OpenSSL and GCC updates, many things may fail to build.
183: any failure that looks like GCC or openssl is best handled by
184: a clean destdir and objdir. Full cleandir and destdir deletion
185: is recommended if build failures occur.
186:
1.288 martin 187: 20171225:
188: removal of the vadvise syscall requires manual removal of all
189: associated files from the libc build object directory (including
1.289 christos 190: the .depend files) - a command like:
1.288 martin 191: cd $OBJ && find . -type d -name libc | xargs rm -rf
1.289 christos 192: For architectures that support multiple "compat" binary targets,
193: you'll need to cleanup both the regular libc directory and the
1.290 martin 194: compat ones (the above command will do that).
1.288 martin 195:
1.287 kre 196: 20171010:
197: a change to the build structure of external/bsd/acpica/bin/iasl
198: means that its objdir (or *.d and .depend at least) might need
199: to be manually removed - or a build done once without -u.
200:
1.286 mrg 201: 20170822:
202: a new version of GMP has been imported and probably
203: will break parts of builds related to themselves or GCC, both
204: in the tools and the native section. Remove all GCC, GMP, MPFR
205: and MPC objdirs or build once without -u.
206:
1.285 mrg 207: 20170816:
208: a new version of MPFR and MPC have been imported and probably
209: will break parts of builds related to themselves or GCC, both
210: in the tools and the native section. Remove all GCC, GMP, MPFR
211: and MPC objdirs or build once without -u.
212:
1.284 martin 213: 20170402:
214: a new version of dhcpcd has been imported, which does not support
215: update builds from the previous version. Remove your
216: external/bsd/dhcpcd object dir or build once without -u.
217:
1.281 roy 218: 20170211:
219: a new terminfo database has been imported.
220: The structure of it has changed slightly from prior versions and
221: an updated tic tool is required.
222: If you build.sh, don't use -u
223:
1.280 kre 224: 20170207:
1.278 kre 225: various arch dependent libc/exect.S files were removed
1.279 kre 226: Either remove the obj directories (lib/libc and compat/amd64/i386/lib
227: if it exists) or do a clean build.
228: (This is a bug in the make system, it should be corrected without
229: human intervention, but isn't.)
1.278 kre 230:
1.277 martin 231: 20170104:
232: xinput build options have changed.
233: Remove the obj directory (external/mit/xorg/bin/xinput)
234: if you build.sh -u
235:
1.276 martin 236: 20170103:
237: a new version of flex has been imported.
238: Remove the file from obj (external/bsd/flex)
239: if you build.sh -u
240:
1.275 spz 241: 20161014:
242: a new version of OpenSSL has been imported.
243: Remove the files from obj (crypto/external/bsd/openssl)
244: if you build.sh -u
245:
1.274 martin 246: 20161009:
247: a new version of dhcpcd has been imported with slightly changed
248: build infrastructure. When doing a build.sh -u this requires
249: pruning the external/bsd/dhcpcd objdir.
250:
1.273 mrg 251: 20160914:
252: i386, amd64, shark, ofppc and macppc have joined shark and x68k
253: ports in using xorg-server 1.18. This requires a clean destdir
254: and a clean objdir.
255:
1.272 dholland 256: 20160527:
257: i386 needs a full cleandir or objdir deletion because PIE has
258: been enabled. (see the amd64 entry two down for further info)
259:
1.270 christos 260: 20160418:
261: libedit needs manual removal of all autogenerated files since
1.271 christos 262: some of them are not autogenerated anymore. Remember that there
263: might be two copies of libedit if your platform builds "compat".
1.270 christos 264:
1.268 riastrad 265: 20160410:
266: amd64 needs full "make cleandir" or deletion of objdir now that
267: PIE has been enabled for amd64. PIE, or position-independent
268: executables, means all code, including executables and not just
269: shared libraries, is position-independent and hence able to be
270: relocated by ASLR, address space layout randomization.
271:
272: The change was made in Makefile variables for compiler and
273: linker flags, for which make(1) does not record dependencies,
274: hence it is unable to detect that all .o files need rebuilding.
275:
276: Partial rebuilds with some modified source files will likely
277: fail when linking executables, since the linker refuses to mix
278: position-independent code with position-dependent code in
279: position-independent executables:
280:
281: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
282:
1.267 mrg 283: 20160401:
284: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 285: Some people have found that cleandir is not sufficient, so if
286: in doubt delete the entire object directory tree for gcc.
1.267 mrg 287:
1.266 aymeric 288: 20160306:
1.265 aymeric 289: NetBSD's regexp implementation is now part of libnbcompat.
290: Nblex, nbm4, nbpax, nbsed use it and they may crash on
291: non-NetBSD hosts if linked with stale object files produced
292: while they included a non-NetBSD regex.h.
293: In any case, you should "make cleandir" at least these tools
294: before updating your toolchain.
295:
1.264 martin 296: 20160125:
297: Dtrace has been enabled by default on some architectures.
298: When doing an update build, make sure to clean the etc/mtree
299: object directory before starting the build - otherwise the
300: needed directories in destdir will not be created.
301: An easy way to do this is:
302: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
303:
1.263 dholland 304: 20150818:
305: New acpica requires "make cleandir" in src/external/bsd/acpica
306: again.
307:
1.262 christos 308: 20150413:
309: New acpica requires "make cleandir" and reinstalling yacc
310: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
311: also "make cleandir" in /usr/src/external/bsd/acpica.
312:
1.261 martin 313: 20150404:
314: Lint changes require a full rebuild of the tool, so make
315: sure to build without -u option to build.sh, or manually
316: do a make cleandir in src/tools/lint1 and
317: src/usr.bin/xlint.
318:
1.260 skrll 319: 20150310:
320: Improvements to openssl for arm mean that update builds of
321: the openssl libraries will fail. A make cleandir in
322: external/bsd/openssl/lib is needed
323:
1.258 martin 324: 20141026:
1.259 msaitoh 325: A mishap during the import of pppd may cause your corruption
1.258 martin 326: in your cvs directory if you happened to do a cvs update
327: during a short period of time. To fix, just remove the
328: directory src/external/bsd/ppp/dist/pppd completely
329: and let cvs restore it on next update.
330:
1.256 apb 331: 20140721:
332: The src/external/mit/lua/src directory was accidentally created
333: and then deleted in the CVS repository. If you get errors like
334:
335: cvs [update aborted]: cannot open directory
336: /cvsroot/src/external/mit/lua/src: No such file or directory
337:
338: then delete your local copy of that directory tree and try again.
339:
1.255 joerg 340: 20140530:
341: ARM eABI switched to DWARF based exception handling. This requires
342: rebuilding all C++ code. It is strongly advised to do a clean build.
343:
1.251 martin 344: 20140131:
1.253 joerg 345: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 346: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 347: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 348:
1.250 christos 349: 20131227:
350: 1. The new ntpd runs in a restricted mode to prevent amplification
351: attacks. If you need ntpdc to work you need to explicitly enable
352: mode7 in your config file. Make sure you put the necessary restrict
353: statements to avoid being exposed.
354: 2. strncat has moved from lib/libc to common/lib/libc; you might need
355: to make clean in libc
356:
1.249 mrg 357: 20131129:
358: The GMP sources were updated, and builds will likely fail without
359: cleaning their build trees for both tools and in-tree, like below.
360:
1.248 mrg 361: 20131128:
362: The MPC and MPFR sources were updated, and builds may require their
363: tools and in-tree directories cleaned for successful updates.
364:
1.246 martin 365: 20130605:
1.247 spz 366: The kernel option FAST_IPSEC no longer exists, it's been renamed
367: to IPSEC (and the older IPSEC version removed).
368:
369: 20130605:
1.246 martin 370: Previous freetype installations eroneously installed private
371: header files. If you are building against a non-empty $DESTDIR,
372: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
373:
1.245 mrg 374: 20130531:
375: The xdm update may cause build failure due to xdm.man being
376: in the obj tree. Make sure to ensure any like this:
377: nbmake: nbmake: don't know how to make xdm.man. Stop
378: is fixed by deleting the xdm.man in the obj tree.
379:
1.244 mrg 380: 20130530:
381: Updates of many xsrc packages will leave old .pc files around.
382: Best to clean out the xsrc objdir entirely before rebuilds.
383:
1.242 christos 384: 20130301:
385: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 386: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 387:
1.238 dholland 388: 20120726:
1.241 wiz 389: The update of OpenSSL requires cleaning both the OpenSSL build
390: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 391: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 392: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 393: cause third-party software to link incorrectly and/or crash.
1.238 dholland 394:
1.237 wiz 395: 20120507:
1.241 wiz 396: The database schema for makemandb was changed. You will
1.237 wiz 397: need to update the database using 'makemandb -f' or wait
398: for the next weekly run to fix it.
399:
1.236 bsh 400: 20120319:
401: sys/conf/Makefile.kern.inc has been modified to adjust the
402: size of db_symtab automatically. You need to update dbsym in
403: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
404: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
405: mk.conf.
406:
1.235 joerg 407: 20120216:
1.241 wiz 408: Default for MKCATPAGES changed to NO. Update builds will fail
409: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 410: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 411: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 412: the next run of weekly will fix it.
1.233 joerg 413:
1.232 christos 414: 20111227:
415: If you built between 20111225 and 20111227 you need to remove
416: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
417: bump has been reverted.
418:
1.231 tls 419: 20111125:
420: The "rnd" pseudodevice has been added to sys/conf/std, which
421: means it should no longer be explicitly listed in kernel
422: configuration files. The line "pseudo-device rnd" should be
423: removed from any custom kernel config files users may have.
424:
1.230 tls 425: 20111119:
426: A problem with the datastructures used by the rndctl(8)
427: utility (pointers in datastructures in an array, making 32->64
428: bit compatibility very painful) has been fixed in a
429: non-backwards-compatible way. If you replace your kernel,
430: replace your rndctl executable too.
1.241 wiz 431:
1.229 jym 432: 20111001:
433: the prop_*_send_syscall() functions from proplib(3) have been
434: changed and their new version is not backward compatible with the old
1.241 wiz 435: one. So ensure that all consumers of these functions (currently:
1.229 jym 436: quota2 code and its tests) are updated together with the new lib.
437:
1.228 mrg 438: 20110817:
439: sparc has been changed to use GCC 4.5.3, so any objdir or
440: DESTDIR for them should be deleted before updating.
441:
1.227 riastrad 442: 20110806:
443: i386 and amd64 have been changed to use GCC 4.5.3, so any
444: objdir or DESTDIR for them should be deleted before updating.
445:
1.226 mrg 446: 20110805:
447: The update to GCC 4.5.3 requires a non-trivial portion of
448: the tree to be cleaned. Best to delete both objdir and
449: DESTDIR before running this update. So far, only the
450: sparc64, mips and powerpc platforms have changed.
451:
1.225 matt 452: 20110803:
1.241 wiz 453: The layout of external/public-domain/xz has changed. To do an
1.225 matt 454: update build you will have to remove the contents of the OBJDIR
455: for external/public-domain/xz/bin by hand as the xz entry there
456: is now a directory.
457:
1.223 joerg 458: 20110410:
1.241 wiz 459: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 460: update build you have to clean both tools/binutils and
461: tools/gcc by hand.
1.223 joerg 462:
1.222 plunky 463: 20110328:
464: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 465: ordering issues with "make all". It may be necessary to remove
1.222 plunky 466: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
467: if your update build fails, as the "Xorg" entry there is now a
468: directory.
469:
1.220 joerg 470: 20110121:
1.221 lukem 471: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 472: the build of individual parts of the tree. This is handled
473: correctly by build.sh. Manual builds have to update /usr/share/mk
474: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 475:
1.217 jruoho 476: 20101217:
477: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 478: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 479: group(5) in order to make the program work with existing setups.
480:
1.216 christos 481: 20101125:
482: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 483: variables with names that contain '='. Revision 1.18 of env.c
484: assumed that this was allowed. Installing a new libc with an
1.216 christos 485: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
486: break which affects the autoconf tests for dependency finding,
487: so building gcc will end up printing:
488: checking dependency style of gcc... none
489: configure: error: no usable dependency style found
490: Fix it by rebuilding and re-installing env.
1.138 lukem 491:
1.215 mrg 492: 20101119:
493: Recent Xorg updates in xsrc/external/mit/ may cause various build
494: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
495: have any build problems with xsrc, or problems with mismatched
496: versions between xorg-server and drivers.
497:
1.213 jmmv 498: 20100604:
499: The update of ATF to 0.9 causes old tests written in shell to fail
500: unless they are rebuilt. If you are building with MKUPDATE=yes,
501: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
502: trees by hand.
503:
1.211 tnozaki 504: 20100522:
1.212 mrg 505: Recent Xorg updates in xsrc/external/mit/ will cause various build
506: problems. Delete your entire DESTDIR and OBJDIR if you have any
507: build problems with xsrc.
508:
509: 20100522:
1.211 tnozaki 510: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 511: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 512:
1.210 christos 513: 20100520:
1.241 wiz 514: The location of the xkb compiled descriptions has changed. Please
1.210 christos 515: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
516:
1.209 njoly 517: 20100222:
518: The shared objects file extension has been changed from .so to
519: .pico, in order to avoid conflicts with shared libraries names
520: libXX.so. All now stale regular .so files can be removed from
521: your object directories.
522:
1.208 roy 523: 20100204:
524: The termcap database has been removed from the sources,
525: but has not been marked obsolete so it is not removed
526: from the system when upgrading.
527: As such, you will need to remove them from your object
528: and destination directories.
529:
1.203 dyoung 530: 20091101:
1.205 dholland 531: After updating, it may be necessary to make the 'cleandir'
532: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
533: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
534: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 535:
1.202 mrg 536: 20091001:
1.206 dholland 537: On amd64 you must rebuild tools (to get the new binutils)
538: before building a kernel, or the build fails on cpufunc.S.
539:
540: 20091001:
1.202 mrg 541: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
542: symlink, failing the build. Delete the link, and the subdir
543: it is in, and retry your build.
544:
1.201 dsl 545: 20090718:
546: libc build changed so that strchr() provides the extra entry
1.241 wiz 547: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 548: may fail because the archive contains the unwanted index.o.
549: (Similarly for strrchr() and rindex().)
550:
1.198 mrg 551: 20090709:
552: Native Xorg was upgraded again. Builds will probably fail again
553: without a clean objdir, at least for src/external/mit/xorg.
554:
1.197 mrg 555: 20090616:
556: Native Xorg was upgraded. Builds will need a clean objdir for
557: src/external/mit/xorg. Upgrading a system from sets will not
558: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
559: subdirectory has been changed into a file, and this needs to
560: be manually "rm -r"'ed before installing xbase.tgz.
561:
1.195 perry 562: 20090501:
563: Several new functions were added to string.h/libc, and this
564: can cause autoconf problems during the tool build for people
1.241 wiz 565: who fail to clean out their tools objects properly. If you
1.195 perry 566: note messages about stpcpy, stpncpy or strnlen accompanying a
567: failure during the tool build, clean out all your tools
568: objects and start again.
569:
1.194 mrg 570: 20090325:
571: The i386 port was switched to i486 default toolchain. This requires
572: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
573:
1.192 skrll 574: 20090126:
1.241 wiz 575: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 576: need to 'rm -f __posix_fadvise50.*' in the libc build directory
577: to avoid using the old assembly stub.
1.192 skrll 578:
1.191 joerg 579: 20090202:
580: pkg_install now depends on the pkgdb cache for automatic conflict
581: detection. It is recommented to rebuild the cache with
582: ``pkg_admin rebuild''.
583:
1.184 christos 584: 20090110:
1.241 wiz 585: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
586: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 587: This is needed even in the MODULAR kernel because there is
588: conditionally compiled code in rtsock.c.
1.184 christos 589: 2. make sure build.sh completes and the binaries in a chroot work
590: before installing.
591: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 592: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 593: are installed properly, and start building libraries first libc
594: and libutil, install them and then continue building all the
1.241 wiz 595: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 596: the new libraries are installed, you can restart the build.
597: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 598: rebuild the required packages to update their shared libraries.
599: Any package you rebuild will require rebuilding all the packages
600: that depend on it.
1.186 christos 601: 5. Next time you run pwd_mkdb with the new binary, the file
602: will be upgraded and it will not be backwards compatible.
1.190 apb 603: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
604: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 605: for utmp. You are better off removing the old files after
1.190 apb 606: upgrading. The automated clearing of /var/run during
607: boot, and the automated rotating of files in /var/log by
608: newsyslog(8), may mean that you do not have to remove the
609: files manually.
610: 7. The optional accounting file (/var/account/acct, see
611: accton(8)) has not been versioned, and will need to be
612: removed. The automatic rotation of the accounting file by
613: /etc/daily limits the bad consequences of failure to remove
614: the file.
1.196 dholland 615: 8. Application software that writes time_t to binary files on
1.241 wiz 616: disk will break or need attention. Most notably: if you are
1.196 dholland 617: using PostgreSQL < 8.4, you need to dump your databases,
618: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 619:
1.183 pgoyette 620: 20081219:
621: config(1) has been updated, and one of the files it creates -
622: swapnetbsd.o - has changed format. You need to rebuild config
623: (done automatically by build.sh) and then you need to rerun
624: config on all kernel configuration files before rebuilding those
625: kernels.
626:
1.181 cube 627: 20081205:
628: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
629: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
630: set and will appear as extra files for MKX11=no update builds.

1.179 tsutsui 632: 20081122:
1.182 tsutsui 633: On i386, various kernel options(4) in GENERIC including
1.180 wiz 634: file systems have been disabled and moved into kernel modules.
635: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 636: following files as well as a new GENERIC kernel:
637:
638: - build and install kernel modules from src/sys/modules
639:
640: - install the latest bootloader, which will load a module
1.180 wiz 641: for the file system from which the kernel is loaded automatically
1.179 tsutsui 642:
1.180 wiz 643: If you have to load your kernel from a file system which is not of
644: the same type as the root file system, you have to load the necessary
645: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 646:
1.178 lukem 647: 20080827:
648: If you built and installed a libc from sources between
649: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
650: which results in false errors reported by lint(1).
651: Since this breaks the libc build itself, manual help is
1.180 wiz 652: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 653: $ (cd lib/libc && make MKLINT=no dependall install)
654:
1.177 christos 655: 20080813:
656: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 657: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 658:
1.200 dholland 659: 20080802:
660: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 661: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 662: for -current.
663:
664: Threaded programs (using libpthread) and C++ programs (using
665: libstdc++) compiled after 20070907 and before 20080802 need to
666: be recompiled.
667:
668: One way to find affected pkgsrc packages:
669:
670: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
671: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO

1.175 simonb 673: 20080731:
674: WAPBL (metadata journaling support) has been added, but at this
675: time isn't backwards compatible with pre-WAPBL aware kernels
676: and userland (fsck_ffs in particular). Please make sure you
677: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 678: especially an uncleanly mounted journaled filesystem. WAPBL
679: also requires the super block to be in the UFS2 format. You
680: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 681:
1.174 lukem 682: 20080721:

1.173 freza 686: 20080531:
1.241 wiz 687: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
688: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 689: utility needs to be rebuilt and reinstalled as older binaries
1.241 wiz 690: won't work correctly. The following sequence of commands:
1.173 freza 691:

713: The posix_fadvise system call has been changed from an assembly
1.241 wiz 714: stub, to a c file that calls an assembly stub. You need to
1.170 christos 715: 'rm -f posix_fadvise.* .depend' in the libc build directory to

1.166 xtraeme 729:
1.165 jmmv 730: 20071028:
731: The pccons(4) driver has been removed from the NetBSD/shark port.
732: You need to update any custom kernel configuration file you have
733: to remove any references to pccons (which includes removing the
734: now useless XSERVER option) and replace them with the correct

1.164 gdt 738: 20070913:
739: A latent bug in dhclient/dhcpd that caused it to be unable to
740: enumerate interfaces was fixed. The bug began to cause
741: problems after 20070911 when the kernel's SIOCGIFCONF
742: implementation was repaired. From 20070529 to 20070911 racoon
743: could not enumerate interfaces. (These are noted because
744: normal kernel/userspace version matching hygiene is not
745: sufficient to avoid this problem.) Ensure that both kernel
746: and userland are from after 20070913.
747:
1.163 joerg 748: 20070703:
1.241 wiz 749: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
1.199 dholland 750: calls the target-specific strip program, and the logic to pass

1.161 dsl 754: 20070422:
755: The way OS emulations lookup filenames inside the emulation root
756: has been changed. Rather than modify the pathname (and copy back
757: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 758: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 759: root file system will be relative to that file system - unless they
1.161 dsl 760: start /../ this is useful when the emulated root is a real install
761: that has such links.

786: The threading model was changed when the newlock2 branch
787: was merged to NetBSD-current. If you boot with a new
788: kernel (version 4.99.10), then you also need a new pthread
789: library (/usr/lib/libpthread.so.0.7). If you boot with
790: an old kernel, then you need the old pthread library
791: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and

819: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
820: kernel configuration for an example. X servers from the last

1.1 abs 834: Hints for a more successful build:
835: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 836: Use build.sh, but do not use its "expert mode":
1.132 jmmv 837: This will automatically build the tools in the
1.123 jmc 838: correct order, and it will keep the tools and the
839: new build products from interfering with the running
840: system. This will allow you to ignore most of the
841: other advice in this file.
1.2 mrg 842: Build a new kernel first:
843: This makes sure that any new system calls or features
844: expected by the new userland will be present. This
845: helps to avoid critical errors when upgrading.
1.1 abs 846: Use object directories:
847: This helps to keep stale object
848: files from polluting the build if a Makefile "forgets"
849: about one. It also makes it easier to clean up after
850: a build. It's also necessary if you want to use the
851: same source tree for multiple machines.
1.123 jmc 852: To use object directories with build.sh:
853: a) invoke build.sh with the "-M" or "-O" options.
854: To use object directories without using build.sh:
1.1 abs 855: a) cd /usr/src ; make cleandir
1.2 mrg 856: b) Add "OBJMACHINE=yes" to /etc/mk.conf
857: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 858: d) cd /usr/src ; make build
1.2 mrg 859: Note that running "make obj" in a directory will create
860: in obj.$MACHINE directory.
1.1 abs 861: Build to a DESTDIR:
1.123 jmc 862: This helps to keep old installed files (especially libraries)
863: from interfering with the new build.
864: To build to a DESTDIR with build.sh, use the "-D" option.
865: To build to a DESTDIR without using build.sh, set the DESTDIR
866: environment variable before running make build. It should be
867: set to the pathname of an initially empty directory.
868: Problems: if you do not use build.sh, you might need to
869: update critical utilities without using DESTDIR since
870: nothing is executed from what is installed in DESTDIR.
871: (See critical utils, below.)
1.1 abs 872: Build often:
873: This keeps critical utilities current enough to not choke
874: on any other part of the source tree that depends on up to
1.123 jmc 875: date functionality. If you use build.sh, you should not have
876: this problem.
1.241 wiz 877:
1.1 abs 878: What to do if things don't work:
879: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 880: When things don't work there are usually a few things that commonly
1.1 abs 881: should be done.
882: 1) make includes
883: This should be done automatically by make build.
884: 2) cd share/mk && make install
885: Again, automatically done by make build.
886:
887: Failsafe rebuild of a small part of the tree:
888: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
889: To make sure you rebuild something correctly you want to do
890: something like the following:
891: 1) Make sure the includes and .mk files are up to date.
892: 2) Make sure any program used to build the particular
893: utility is up to date. (yacc, lex, etc...)
894: 3) cd ...path/to/util...
895: make cleandir
896: rm ...all obj directories...
897: make cleandir # yes, again
898: make obj
899: make depend && make
900:
901: Failsafe rebuild of the entire tree:
902: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
903: If you really want to make sure the source tree is clean and
1.2 mrg 904: ready for a build try the following. Note that sourcing /etc/mk.conf
905: (a make(1) Makefile) in this manner is not right, and will not work
906: for anyone who uses any make(1) features in /etc/mk.conf.

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

1000: Fix: Recursively delete the affected directory from your working tree
1001: and try the update again.
