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

1.179 tsutsui 483: 20081122:
1.182 tsutsui 484: On i386, various kernel options(4) in GENERIC including
1.180 wiz 485: file systems have been disabled and moved into kernel modules.
486: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 487: following files as well as a new GENERIC kernel:
488:
489: - build and install kernel modules from src/sys/modules
490:
491: - install the latest bootloader, which will load a module
1.180 wiz 492: for the file system from which the kernel is loaded automatically
1.179 tsutsui 493:
1.180 wiz 494: If you have to load your kernel from a file system which is not of
495: the same type as the root file system, you have to load the necessary
496: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 497:
1.178 lukem 498: 20080827:
499: If you built and installed a libc from sources between
500: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
501: which results in false errors reported by lint(1).
502: Since this breaks the libc build itself, manual help is
1.180 wiz 503: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 504: $ (cd lib/libc && make MKLINT=no dependall install)
505:
1.177 christos 506: 20080813:
507: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 508: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 509:
1.200 dholland 510: 20080802:
511: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 512: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 513: for -current.
514:
515: Threaded programs (using libpthread) and C++ programs (using
516: libstdc++) compiled after 20070907 and before 20080802 need to
517: be recompiled.
518:
519: One way to find affected pkgsrc packages:
520:
521: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
522: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
523:
1.175 simonb 524: 20080731:
525: WAPBL (metadata journaling support) has been added, but at this
526: time isn't backwards compatible with pre-WAPBL aware kernels
527: and userland (fsck_ffs in particular). Please make sure you
528: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 529: especially an uncleanly mounted journaled filesystem. WAPBL
530: also requires the super block to be in the UFS2 format. You
531: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 532:
1.174 lukem 533: 20080721:

1.173 freza 537: 20080531:
1.241 wiz 538: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
539: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 540: utility needs to be rebuilt and reinstalled as older binaries
1.241 wiz 541: won't work correctly. The following sequence of commands:
1.173 freza 542:
543: $ (cd sys/sys/ && nbmake-$arch includes)
544: $ (cd sbin/drvctl/ && nbmake-$arch clean)
545: $ (cd sbin/drvctl/ && nbmake-$arch all)

561: Linker warnings are now fatal if $WARNS>0.
562:
1.170 christos 563: 20080126:
564: The posix_fadvise system call has been changed from an assembly
1.241 wiz 565: stub, to a c file that calls an assembly stub. You need to
1.170 christos 566: 'rm -f posix_fadvise.* .depend' in the libc build directory to
567: avoid using the old assembly stub.
568:
1.168 joerg 569: 20071209:
1.241 wiz 570: The acpiec(4) driver has been split into two attachments. If you
1.168 joerg 571: get ACPI errors before the attachment, please update your kernel
1.169 wiz 572: configuration file appropriately or see GENERIC for more details.
1.168 joerg 573:
1.166 xtraeme 574: 20071115:
575: The it(4) driver has been renamed to itesio(4) and the old port
576: argument specified in the kernel configuration file is not valid
1.241 wiz 577: anymore. The itesio(4) driver now uses the Super I/O address port
578: rather than the EC address port. Please update your kernel
1.167 wiz 579: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 580:
1.165 jmmv 581: 20071028:
582: The pccons(4) driver has been removed from the NetBSD/shark port.
583: You need to update any custom kernel configuration file you have
584: to remove any references to pccons (which includes removing the
585: now useless XSERVER option) and replace them with the correct
586: entries for the wscons driver. See the GENERIC configuration file
587: for more details.
588:
1.164 gdt 589: 20070913:
590: A latent bug in dhclient/dhcpd that caused it to be unable to
591: enumerate interfaces was fixed. The bug began to cause
592: problems after 20070911 when the kernel's SIOCGIFCONF
593: implementation was repaired. From 20070529 to 20070911 racoon
594: could not enumerate interfaces. (These are noted because
595: normal kernel/userspace version matching hygiene is not
596: sufficient to avoid this problem.) Ensure that both kernel
597: and userland are from after 20070913.
598:
1.163 joerg 599: 20070703:
1.241 wiz 600: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
1.199 dholland 601: calls the target-specific strip program, and the logic to pass
602: down STRIP from make has been removed. This requires a
603: re-installation of tools.
1.163 joerg 604:
1.161 dsl 605: 20070422:
606: The way OS emulations lookup filenames inside the emulation root
607: has been changed. Rather than modify the pathname (and copy back
608: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 609: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 610: root file system will be relative to that file system - unless they
1.161 dsl 611: start /../ this is useful when the emulated root is a real install
612: that has such links.
613: This might affect symlinks that have been added to reference outside

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

637: The threading model was changed when the newlock2 branch
638: was merged to NetBSD-current. If you boot with a new
639: kernel (version 4.99.10), then you also need a new pthread
640: library (/usr/lib/libpthread.so.0.7). If you boot with
641: an old kernel, then you need the old pthread library
642: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
643: the pthread library in sync, old threaded applications should
644: continue to work with an old or new kernel. Note that named(8)

1.1 abs 685: Hints for a more successful build:
686: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 687: Use build.sh, but do not use its "expert mode":
1.132 jmmv 688: This will automatically build the tools in the
1.123 jmc 689: correct order, and it will keep the tools and the
690: new build products from interfering with the running
691: system. This will allow you to ignore most of the
692: other advice in this file.
1.2 mrg 693: Build a new kernel first:
694: This makes sure that any new system calls or features
695: expected by the new userland will be present. This
696: helps to avoid critical errors when upgrading.
1.1 abs 697: Use object directories:
698: This helps to keep stale object
699: files from polluting the build if a Makefile "forgets"
700: about one. It also makes it easier to clean up after
701: a build. It's also necessary if you want to use the
702: same source tree for multiple machines.
1.123 jmc 703: To use object directories with build.sh:
704: a) invoke build.sh with the "-M" or "-O" options.
705: To use object directories without using build.sh:
1.1 abs 706: a) cd /usr/src ; make cleandir
1.2 mrg 707: b) Add "OBJMACHINE=yes" to /etc/mk.conf
708: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 709: d) cd /usr/src ; make build
1.2 mrg 710: Note that running "make obj" in a directory will create
711: in obj.$MACHINE directory.
1.1 abs 712: Build to a DESTDIR:
1.123 jmc 713: This helps to keep old installed files (especially libraries)
714: from interfering with the new build.
715: To build to a DESTDIR with build.sh, use the "-D" option.
716: To build to a DESTDIR without using build.sh, set the DESTDIR
717: environment variable before running make build. It should be
718: set to the pathname of an initially empty directory.
719: Problems: if you do not use build.sh, you might need to
720: update critical utilities without using DESTDIR since
721: nothing is executed from what is installed in DESTDIR.
722: (See critical utils, below.)
1.1 abs 723: Build often:
724: This keeps critical utilities current enough to not choke
725: on any other part of the source tree that depends on up to
1.123 jmc 726: date functionality. If you use build.sh, you should not have
727: this problem.

1.230 tls 731: When things don't work there are usually a few things that commonly

733: 1) make includes
734: This should be done automatically by make build.
735: 2) cd share/mk && make install
736: Again, automatically done by make build.
737:
738: Failsafe rebuild of a small part of the tree:
739: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
740: To make sure you rebuild something correctly you want to do
741: something like the following:
742: 1) Make sure the includes and .mk files are up to date.
743: 2) Make sure any program used to build the particular
744: utility is up to date. (yacc, lex, etc...)
745: 3) cd ...path/to/util...
746: make cleandir
747: rm ...all obj directories...
748: make cleandir # yes, again
749: make obj
750: make depend && make
751:
752: Failsafe rebuild of the entire tree:
753: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
754: If you really want to make sure the source tree is clean and
1.2 mrg 755: ready for a build try the following. Note that sourcing /etc/mk.conf

844: Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
845: No such file or directory.
846: Cause: If a directory is created by mistake, then it is sometimes
847: deleted from the CVS repository using administrative commands
848: that bypass the normal cvs access controls. If your cvs working tree
849: contains references to a directory that has been deleted on the
850: server in this way, then "cvs update" reports this error.
851: Fix: Recursively delete the affected directory from your working tree
852: and try the update again.
