1.297 ! joerg 1: $NetBSD: UPDATING,v 1.296 2018/07/16 11:45:01 martin Exp $
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.

1.123 jmc 17: See also: BUILDING, build.sh, Makefile.
1.1 abs 18:
19: Recent changes:
20: ^^^^^^^^^^^^^^^
1.230 tls 21:
1.297 ! joerg 22: 20180717:
! 23: On aarch64 int64_t and related types have changed from long long
! 24: to long. This requires recompiling all C++ binaries.
! 25:
1.296 martin 26: 20180713:
27: On amd64 and i386 static binaries are now build position
28: independend. This requires recompilation of all object
29: files used to create the crunched /rescue binary.
30: Clean the rescue directory in your obj directory before
31: doing an update build, otherwise linking will fail.
32:
1.293 jakllsch 33: 20180414:
34: Existing binutils was migrated to binutils.old. Manual
35: removal of tools/binutils objects directory may be required
36: to fix tools build failure.
37:
1.292 mrg 38: 20180311:
39: bdftopcf was updated and may need cleaning in the
40: src/external/mit/xorg/tools/bdftopcf subdirectory if there are
41: link errors.
42:
1.291 mrg 43: 20180212:
44: between OpenSSL and GCC updates, many things may fail to build.
45: any failure that looks like GCC or openssl is best handled by
46: a clean destdir and objdir. Full cleandir and destdir deletion
47: is recommended if build failures occur.
48:
1.288 martin 49: 20171225:
50: removal of the vadvise syscall requires manual removal of all
51: associated files from the libc build object directory (including
1.289 christos 52: the .depend files) - a command like:
1.288 martin 53: cd $OBJ && find . -type d -name libc | xargs rm -rf
1.289 christos 54: For architectures that support multiple "compat" binary targets,
55: you'll need to cleanup both the regular libc directory and the
1.290 martin 56: compat ones (the above command will do that).
1.288 martin 57:
1.287 kre 58: 20171010:
59: a change to the build structure of external/bsd/acpica/bin/iasl
60: means that its objdir (or *.d and .depend at least) might need
61: to be manually removed - or a build done once without -u.
62:
1.286 mrg 63: 20170822:
64: a new version of GMP has been imported and probably
65: will break parts of builds related to themselves or GCC, both
66: in the tools and the native section. Remove all GCC, GMP, MPFR
67: and MPC objdirs or build once without -u.
68:
1.285 mrg 69: 20170816:
70: a new version of MPFR and MPC have been imported and probably
71: will break parts of builds related to themselves or GCC, both
72: in the tools and the native section. Remove all GCC, GMP, MPFR
73: and MPC objdirs or build once without -u.
74:
1.284 martin 75: 20170402:
76: a new version of dhcpcd has been imported, which does not support
77: update builds from the previous version. Remove your
78: external/bsd/dhcpcd object dir or build once without -u.
79:
1.281 roy 80: 20170211:
81: a new terminfo database has been imported.
82: The structure of it has changed slightly from prior versions and
83: an updated tic tool is required.
84: If you build.sh, don't use -u
85:
1.280 kre 86: 20170207:
1.278 kre 87: various arch dependent libc/exect.S files were removed
1.279 kre 88: Either remove the obj directories (lib/libc and compat/amd64/i386/lib
89: if it exists) or do a clean build.
90: (This is a bug in the make system, it should be corrected without
91: human intervention, but isn't.)
1.278 kre 92:
1.277 martin 93: 20170104:
94: xinput build options have changed.
95: Remove the obj directory (external/mit/xorg/bin/xinput)
96: if you build.sh -u
97:
1.276 martin 98: 20170103:
99: a new version of flex has been imported.
100: Remove the file from obj (external/bsd/flex)
101: if you build.sh -u
102:
1.275 spz 103: 20161014:
104: a new version of OpenSSL has been imported.
105: Remove the files from obj (crypto/external/bsd/openssl)
106: if you build.sh -u
107:
1.274 martin 108: 20161009:
109: a new version of dhcpcd has been imported with slightly changed
110: build infrastructure. When doing a build.sh -u this requires
111: pruning the external/bsd/dhcpcd objdir.
112:
1.273 mrg 113: 20160914:
114: i386, amd64, shark, ofppc and macppc have joined shark and x68k
115: ports in using xorg-server 1.18. This requires a clean destdir
116: and a clean objdir.
117:
1.272 dholland 118: 20160527:
119: i386 needs a full cleandir or objdir deletion because PIE has
120: been enabled. (see the amd64 entry two down for further info)
121:
1.270 christos 122: 20160418:
123: libedit needs manual removal of all autogenerated files since
1.271 christos 124: some of them are not autogenerated anymore. Remember that there
125: might be two copies of libedit if your platform builds "compat".
1.270 christos 126:
1.268 riastrad 127: 20160410:
128: amd64 needs full "make cleandir" or deletion of objdir now that
129: PIE has been enabled for amd64. PIE, or position-independent
130: executables, means all code, including executables and not just
131: shared libraries, is position-independent and hence able to be
132: relocated by ASLR, address space layout randomization.
133:
134: The change was made in Makefile variables for compiler and
135: linker flags, for which make(1) does not record dependencies,
136: hence it is unable to detect that all .o files need rebuilding.
137:
138: Partial rebuilds with some modified source files will likely
139: fail when linking executables, since the linker refuses to mix
140: position-independent code with position-dependent code in
141: position-independent executables:
142:
143: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
144:
1.267 mrg 145: 20160401:
146: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 147: Some people have found that cleandir is not sufficient, so if
148: in doubt delete the entire object directory tree for gcc.
1.267 mrg 149:
1.266 aymeric 150: 20160306:
1.265 aymeric 151: NetBSD's regexp implementation is now part of libnbcompat.
152: Nblex, nbm4, nbpax, nbsed use it and they may crash on
153: non-NetBSD hosts if linked with stale object files produced
154: while they included a non-NetBSD regex.h.
155: In any case, you should "make cleandir" at least these tools
156: before updating your toolchain.
157:
1.264 martin 158: 20160125:
159: Dtrace has been enabled by default on some architectures.
160: When doing an update build, make sure to clean the etc/mtree
161: object directory before starting the build - otherwise the
162: needed directories in destdir will not be created.
163: An easy way to do this is:
164: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
165:
1.263 dholland 166: 20150818:
167: New acpica requires "make cleandir" in src/external/bsd/acpica
168: again.
169:
1.262 christos 170: 20150413:
171: New acpica requires "make cleandir" and reinstalling yacc
172: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
173: also "make cleandir" in /usr/src/external/bsd/acpica.
174:
1.261 martin 175: 20150404:
176: Lint changes require a full rebuild of the tool, so make
177: sure to build without -u option to build.sh, or manually
178: do a make cleandir in src/tools/lint1 and
179: src/usr.bin/xlint.
180:
1.260 skrll 181: 20150310:
182: Improvements to openssl for arm mean that update builds of
183: the openssl libraries will fail. A make cleandir in
184: external/bsd/openssl/lib is needed
185:
1.258 martin 186: 20141026:
1.259 msaitoh 187: A mishap during the import of pppd may cause your corruption
1.258 martin 188: in your cvs directory if you happened to do a cvs update
189: during a short period of time. To fix, just remove the
190: directory src/external/bsd/ppp/dist/pppd completely
191: and let cvs restore it on next update.
192:
1.256 apb 193: 20140721:
194: The src/external/mit/lua/src directory was accidentally created
195: and then deleted in the CVS repository. If you get errors like
196:
197: cvs [update aborted]: cannot open directory
198: /cvsroot/src/external/mit/lua/src: No such file or directory
199:
200: then delete your local copy of that directory tree and try again.
201:
1.255 joerg 202: 20140530:
203: ARM eABI switched to DWARF based exception handling. This requires
204: rebuilding all C++ code. It is strongly advised to do a clean build.
205:
1.251 martin 206: 20140131:
1.253 joerg 207: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 208: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 209: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 210:
1.250 christos 211: 20131227:
212: 1. The new ntpd runs in a restricted mode to prevent amplification
213: attacks. If you need ntpdc to work you need to explicitly enable
214: mode7 in your config file. Make sure you put the necessary restrict
215: statements to avoid being exposed.
216: 2. strncat has moved from lib/libc to common/lib/libc; you might need
217: to make clean in libc
218:
1.249 mrg 219: 20131129:
220: The GMP sources were updated, and builds will likely fail without
221: cleaning their build trees for both tools and in-tree, like below.
222:
1.248 mrg 223: 20131128:
224: The MPC and MPFR sources were updated, and builds may require their
225: tools and in-tree directories cleaned for successful updates.
226:
1.246 martin 227: 20130605:
1.247 spz 228: The kernel option FAST_IPSEC no longer exists, it's been renamed
229: to IPSEC (and the older IPSEC version removed).
230:
231: 20130605:
1.246 martin 232: Previous freetype installations eroneously installed private
233: header files. If you are building against a non-empty $DESTDIR,
234: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
235:
1.245 mrg 236: 20130531:
237: The xdm update may cause build failure due to xdm.man being
238: in the obj tree. Make sure to ensure any like this:
239: nbmake: nbmake: don't know how to make xdm.man. Stop
240: is fixed by deleting the xdm.man in the obj tree.
241:
1.244 mrg 242: 20130530:
243: Updates of many xsrc packages will leave old .pc files around.
244: Best to clean out the xsrc objdir entirely before rebuilds.
245:
1.242 christos 246: 20130301:
247: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 248: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 249:
1.238 dholland 250: 20120726:
1.241 wiz 251: The update of OpenSSL requires cleaning both the OpenSSL build
252: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 253: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 254: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 255: cause third-party software to link incorrectly and/or crash.
1.238 dholland 256:
1.237 wiz 257: 20120507:
1.241 wiz 258: The database schema for makemandb was changed. You will
1.237 wiz 259: need to update the database using 'makemandb -f' or wait
260: for the next weekly run to fix it.
261:
1.236 bsh 262: 20120319:
263: sys/conf/Makefile.kern.inc has been modified to adjust the
264: size of db_symtab automatically. You need to update dbsym in
265: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
266: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
267: mk.conf.
268:
1.235 joerg 269: 20120216:
1.241 wiz 270: Default for MKCATPAGES changed to NO. Update builds will fail
271: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 272: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 273: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 274: the next run of weekly will fix it.
1.233 joerg 275:
1.232 christos 276: 20111227:
277: If you built between 20111225 and 20111227 you need to remove
278: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
279: bump has been reverted.
280:
1.231 tls 281: 20111125:
282: The "rnd" pseudodevice has been added to sys/conf/std, which
283: means it should no longer be explicitly listed in kernel
284: configuration files. The line "pseudo-device rnd" should be
285: removed from any custom kernel config files users may have.
286:
1.230 tls 287: 20111119:
288: A problem with the datastructures used by the rndctl(8)
289: utility (pointers in datastructures in an array, making 32->64
290: bit compatibility very painful) has been fixed in a
291: non-backwards-compatible way. If you replace your kernel,
292: replace your rndctl executable too.
1.241 wiz 293:
1.229 jym 294: 20111001:
295: the prop_*_send_syscall() functions from proplib(3) have been
296: changed and their new version is not backward compatible with the old
1.241 wiz 297: one. So ensure that all consumers of these functions (currently:
1.229 jym 298: quota2 code and its tests) are updated together with the new lib.
299:
1.228 mrg 300: 20110817:
301: sparc has been changed to use GCC 4.5.3, so any objdir or
302: DESTDIR for them should be deleted before updating.
303:
1.227 riastrad 304: 20110806:
305: i386 and amd64 have been changed to use GCC 4.5.3, so any
306: objdir or DESTDIR for them should be deleted before updating.
307:
1.226 mrg 308: 20110805:
309: The update to GCC 4.5.3 requires a non-trivial portion of
310: the tree to be cleaned. Best to delete both objdir and
311: DESTDIR before running this update. So far, only the
312: sparc64, mips and powerpc platforms have changed.
313:
1.225 matt 314: 20110803:
1.241 wiz 315: The layout of external/public-domain/xz has changed. To do an
1.225 matt 316: update build you will have to remove the contents of the OBJDIR
317: for external/public-domain/xz/bin by hand as the xz entry there
318: is now a directory.
319:
1.223 joerg 320: 20110410:
1.241 wiz 321: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 322: update build you have to clean both tools/binutils and
323: tools/gcc by hand.
1.223 joerg 324:
1.222 plunky 325: 20110328:
326: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 327: ordering issues with "make all". It may be necessary to remove
1.222 plunky 328: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
329: if your update build fails, as the "Xorg" entry there is now a
330: directory.
331:
1.220 joerg 332: 20110121:
1.221 lukem 333: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 334: the build of individual parts of the tree. This is handled
335: correctly by build.sh. Manual builds have to update /usr/share/mk
336: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 337:
1.217 jruoho 338: 20101217:
339: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 340: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 341: group(5) in order to make the program work with existing setups.
342:
1.216 christos 343: 20101125:
344: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 345: variables with names that contain '='. Revision 1.18 of env.c
346: assumed that this was allowed. Installing a new libc with an
1.216 christos 347: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
348: break which affects the autoconf tests for dependency finding,
349: so building gcc will end up printing:
350: checking dependency style of gcc... none
351: configure: error: no usable dependency style found
352: Fix it by rebuilding and re-installing env.
1.138 lukem 353:
1.215 mrg 354: 20101119:
355: Recent Xorg updates in xsrc/external/mit/ may cause various build
356: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
357: have any build problems with xsrc, or problems with mismatched
358: versions between xorg-server and drivers.
359:
1.213 jmmv 360: 20100604:
361: The update of ATF to 0.9 causes old tests written in shell to fail
362: unless they are rebuilt. If you are building with MKUPDATE=yes,
363: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
364: trees by hand.
365:
1.211 tnozaki 366: 20100522:
1.212 mrg 367: Recent Xorg updates in xsrc/external/mit/ will cause various build
368: problems. Delete your entire DESTDIR and OBJDIR if you have any
369: build problems with xsrc.
370:
371: 20100522:
1.211 tnozaki 372: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 373: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 374:
1.210 christos 375: 20100520:
1.241 wiz 376: The location of the xkb compiled descriptions has changed. Please
1.210 christos 377: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
378:
1.209 njoly 379: 20100222:
380: The shared objects file extension has been changed from .so to
381: .pico, in order to avoid conflicts with shared libraries names
382: libXX.so. All now stale regular .so files can be removed from
383: your object directories.
384:
1.208 roy 385: 20100204:
386: The termcap database has been removed from the sources,
387: but has not been marked obsolete so it is not removed
388: from the system when upgrading.
389: As such, you will need to remove them from your object
390: and destination directories.
391:
1.203 dyoung 392: 20091101:
1.205 dholland 393: After updating, it may be necessary to make the 'cleandir'
394: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
395: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
396: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 397:
1.202 mrg 398: 20091001:
1.206 dholland 399: On amd64 you must rebuild tools (to get the new binutils)
400: before building a kernel, or the build fails on cpufunc.S.
401:
402: 20091001:
1.202 mrg 403: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
404: symlink, failing the build. Delete the link, and the subdir
405: it is in, and retry your build.
406:
1.201 dsl 407: 20090718:
408: libc build changed so that strchr() provides the extra entry
1.241 wiz 409: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 410: may fail because the archive contains the unwanted index.o.
411: (Similarly for strrchr() and rindex().)
412:
1.198 mrg 413: 20090709:
414: Native Xorg was upgraded again. Builds will probably fail again
415: without a clean objdir, at least for src/external/mit/xorg.
416:
1.197 mrg 417: 20090616:
418: Native Xorg was upgraded. Builds will need a clean objdir for
419: src/external/mit/xorg. Upgrading a system from sets will not
420: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
421: subdirectory has been changed into a file, and this needs to
422: be manually "rm -r"'ed before installing xbase.tgz.
423:
1.195 perry 424: 20090501:
425: Several new functions were added to string.h/libc, and this
426: can cause autoconf problems during the tool build for people
1.241 wiz 427: who fail to clean out their tools objects properly. If you
1.195 perry 428: note messages about stpcpy, stpncpy or strnlen accompanying a
429: failure during the tool build, clean out all your tools
430: objects and start again.
431:
1.194 mrg 432: 20090325:
433: The i386 port was switched to i486 default toolchain. This requires
434: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
435:
1.192 skrll 436: 20090126:
1.241 wiz 437: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 438: need to 'rm -f __posix_fadvise50.*' in the libc build directory
439: to avoid using the old assembly stub.
1.192 skrll 440:
1.191 joerg 441: 20090202:
442: pkg_install now depends on the pkgdb cache for automatic conflict
443: detection. It is recommented to rebuild the cache with
444: ``pkg_admin rebuild''.
445:
1.184 christos 446: 20090110:
1.241 wiz 447: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
448: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 449: This is needed even in the MODULAR kernel because there is
450: conditionally compiled code in rtsock.c.
1.184 christos 451: 2. make sure build.sh completes and the binaries in a chroot work
452: before installing.
453: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 454: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 455: are installed properly, and start building libraries first libc
456: and libutil, install them and then continue building all the
1.241 wiz 457: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 458: the new libraries are installed, you can restart the build.
459: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 460: rebuild the required packages to update their shared libraries.
461: Any package you rebuild will require rebuilding all the packages
462: that depend on it.
1.186 christos 463: 5. Next time you run pwd_mkdb with the new binary, the file
464: will be upgraded and it will not be backwards compatible.
1.190 apb 465: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
466: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 467: for utmp. You are better off removing the old files after
1.190 apb 468: upgrading. The automated clearing of /var/run during
469: boot, and the automated rotating of files in /var/log by
470: newsyslog(8), may mean that you do not have to remove the
471: files manually.
472: 7. The optional accounting file (/var/account/acct, see
473: accton(8)) has not been versioned, and will need to be
474: removed. The automatic rotation of the accounting file by
475: /etc/daily limits the bad consequences of failure to remove
476: the file.
1.196 dholland 477: 8. Application software that writes time_t to binary files on
1.241 wiz 478: disk will break or need attention. Most notably: if you are
1.196 dholland 479: using PostgreSQL < 8.4, you need to dump your databases,
480: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 481:
1.183 pgoyette 482: 20081219:
483: config(1) has been updated, and one of the files it creates -
484: swapnetbsd.o - has changed format. You need to rebuild config
485: (done automatically by build.sh) and then you need to rerun
486: config on all kernel configuration files before rebuilding those
487: kernels.
488:
1.181 cube 489: 20081205:
490: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
491: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
492: set and will appear as extra files for MKX11=no update builds.

1.179 tsutsui 494: 20081122:
1.182 tsutsui 495: On i386, various kernel options(4) in GENERIC including
1.180 wiz 496: file systems have been disabled and moved into kernel modules.
497: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 498: following files as well as a new GENERIC kernel:
499:
500: - build and install kernel modules from src/sys/modules
501:
502: - install the latest bootloader, which will load a module
1.180 wiz 503: for the file system from which the kernel is loaded automatically
1.179 tsutsui 504:
1.180 wiz 505: If you have to load your kernel from a file system which is not of
506: the same type as the root file system, you have to load the necessary
507: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 508:
1.178 lukem 509: 20080827:
510: If you built and installed a libc from sources between
511: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
512: which results in false errors reported by lint(1).
513: Since this breaks the libc build itself, manual help is
1.180 wiz 514: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 515: $ (cd lib/libc && make MKLINT=no dependall install)
516:
1.177 christos 517: 20080813:
518: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 519: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 520:
1.200 dholland 521: 20080802:
522: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 523: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 524: for -current.
525:
526: Threaded programs (using libpthread) and C++ programs (using
527: libstdc++) compiled after 20070907 and before 20080802 need to
528: be recompiled.
529:
530: One way to find affected pkgsrc packages:
531:
532: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
533: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
534:
1.175 simonb 535: 20080731:
536: WAPBL (metadata journaling support) has been added, but at this
537: time isn't backwards compatible with pre-WAPBL aware kernels
538: and userland (fsck_ffs in particular). Please make sure you
539: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 540: especially an uncleanly mounted journaled filesystem. WAPBL
541: also requires the super block to be in the UFS2 format. You
542: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 543:
1.174 lukem 544: 20080721:

546: isn't defined.
547:
1.173 freza 548: 20080531:
1.241 wiz 549: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
550: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 551: utility needs to be rebuilt and reinstalled as older binaries
1.241 wiz 552: won't work correctly. The following sequence of commands:
1.173 freza 553:
554: $ (cd sys/sys/ && nbmake-$arch includes)
555: $ (cd sbin/drvctl/ && nbmake-$arch clean)
556: $ (cd sbin/drvctl/ && nbmake-$arch all)

562:
1.171 he 563: 20080521:
564: For a while, unprivileged UPDATE builds would fail to
565: succeed at the checkflist stage, complaining that
566: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
567: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
568: If you already hit this problem, update the .mk file,
569: remove ${DESTDIR}/stand/<arch>, and re-run the build.

1.174 lukem 571: 20080303:
572: Linker warnings are now fatal if $WARNS>0.
573:
1.170 christos 574: 20080126:
575: The posix_fadvise system call has been changed from an assembly
1.241 wiz 576: stub, to a c file that calls an assembly stub. You need to
1.170 christos 577: 'rm -f posix_fadvise.* .depend' in the libc build directory to
578: avoid using the old assembly stub.
579:
1.168 joerg 580: 20071209:
1.241 wiz 581: The acpiec(4) driver has been split into two attachments. If you
1.168 joerg 582: get ACPI errors before the attachment, please update your kernel
1.169 wiz 583: configuration file appropriately or see GENERIC for more details.
1.168 joerg 584:
1.166 xtraeme 585: 20071115:
586: The it(4) driver has been renamed to itesio(4) and the old port
587: argument specified in the kernel configuration file is not valid
1.241 wiz 588: anymore. The itesio(4) driver now uses the Super I/O address port
589: rather than the EC address port. Please update your kernel
1.167 wiz 590: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 591:
1.165 jmmv 592: 20071028:
593: The pccons(4) driver has been removed from the NetBSD/shark port.
594: You need to update any custom kernel configuration file you have
595: to remove any references to pccons (which includes removing the
596: now useless XSERVER option) and replace them with the correct
597: entries for the wscons driver. See the GENERIC configuration file
598: for more details.
599:
1.164 gdt 600: 20070913:
601: A latent bug in dhclient/dhcpd that caused it to be unable to
602: enumerate interfaces was fixed. The bug began to cause
603: problems after 20070911 when the kernel's SIOCGIFCONF
604: implementation was repaired. From 20070529 to 20070911 racoon
605: could not enumerate interfaces. (These are noted because
606: normal kernel/userspace version matching hygiene is not
607: sufficient to avoid this problem.) Ensure that both kernel
608: and userland are from after 20070913.
609:
1.163 joerg 610: 20070703:
1.241 wiz 611: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
1.199 dholland 612: calls the target-specific strip program, and the logic to pass
613: down STRIP from make has been removed. This requires a
614: re-installation of tools.
1.163 joerg 615:
1.161 dsl 616: 20070422:
617: The way OS emulations lookup filenames inside the emulation root
618: has been changed. Rather than modify the pathname (and copy back
619: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 620: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 621: root file system will be relative to that file system - unless they
1.161 dsl 622: start /../ this is useful when the emulated root is a real install
623: that has such links.
624: This might affect symlinks that have been added to reference outside
625: the emulated root.

1.160 jmcneill 627: 20070412:
1.241 wiz 628: The pckbc driver on sgimips IP32 has been removed. Use macekbc

1.159 gdt 632: 20070319:
633: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so

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

648: The threading model was changed when the newlock2 branch
649: was merged to NetBSD-current. If you boot with a new
650: kernel (version 4.99.10), then you also need a new pthread
651: library (/usr/lib/libpthread.so.0.7). If you boot with
652: an old kernel, then you need the old pthread library
653: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
654: the pthread library in sync, old threaded applications should
655: continue to work with an old or new kernel. Note that named(8)

1.1 abs 696: Hints for a more successful build:
697: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 698: Use build.sh, but do not use its "expert mode":
1.132 jmmv 699: This will automatically build the tools in the
1.123 jmc 700: correct order, and it will keep the tools and the
701: new build products from interfering with the running
702: system. This will allow you to ignore most of the
703: other advice in this file.
1.2 mrg 704: Build a new kernel first:
705: This makes sure that any new system calls or features
706: expected by the new userland will be present. This
707: helps to avoid critical errors when upgrading.
1.1 abs 708: Use object directories:
709: This helps to keep stale object
710: files from polluting the build if a Makefile "forgets"
711: about one. It also makes it easier to clean up after
712: a build. It's also necessary if you want to use the
713: same source tree for multiple machines.
1.123 jmc 714: To use object directories with build.sh:
715: a) invoke build.sh with the "-M" or "-O" options.
716: To use object directories without using build.sh:
1.1 abs 717: a) cd /usr/src ; make cleandir
1.2 mrg 718: b) Add "OBJMACHINE=yes" to /etc/mk.conf
719: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 720: d) cd /usr/src ; make build
1.2 mrg 721: Note that running "make obj" in a directory will create
722: in obj.$MACHINE directory.
1.1 abs 723: Build to a DESTDIR:
1.123 jmc 724: This helps to keep old installed files (especially libraries)
725: from interfering with the new build.
726: To build to a DESTDIR with build.sh, use the "-D" option.
727: To build to a DESTDIR without using build.sh, set the DESTDIR
728: environment variable before running make build. It should be
729: set to the pathname of an initially empty directory.
730: Problems: if you do not use build.sh, you might need to
731: update critical utilities without using DESTDIR since
732: nothing is executed from what is installed in DESTDIR.
733: (See critical utils, below.)
1.1 abs 734: Build often:
735: This keeps critical utilities current enough to not choke
736: on any other part of the source tree that depends on up to
1.123 jmc 737: date functionality. If you use build.sh, you should not have
738: this problem.

748:
749: Failsafe rebuild of a small part of the tree:
750: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
751: To make sure you rebuild something correctly you want to do
752: something like the following:
753: 1) Make sure the includes and .mk files are up to date.
754: 2) Make sure any program used to build the particular
755: utility is up to date. (yacc, lex, etc...)
756: 3) cd ...path/to/util...
757: make cleandir
758: rm ...all obj directories...

760: make obj
761: make depend && make
762:
763: Failsafe rebuild of the entire tree:
764: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
765: If you really want to make sure the source tree is clean and
1.2 mrg 766: ready for a build try the following. Note that sourcing /etc/mk.conf

827: Fix: Try the following sequence of commands in the directory in question.

829: (If you built the tree without "make obj" in the past, obsolete files
830: may remain. The command tries to clean everything up)

1.257 apb 854:
855: Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
856: No such file or directory.
857: Cause: If a directory is created by mistake, then it is sometimes
858: deleted from the CVS repository using administrative commands
859: that bypass the normal cvs access controls. If your cvs working tree
860: contains references to a directory that has been deleted on the
861: server in this way, then "cvs update" reports this error.
862: Fix: Recursively delete the affected directory from your working tree
863: and try the update again.
