1.238.2.2! tls 1: $NetBSD$
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.

1.230 tls 18:
1.238.2.2! tls 19: 20130605:
! 20: Previous freetype installations eroneously installed private
! 21: header files. If you are building against a non-empty $DESTDIR,
! 22: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
! 23:
! 24: 20130531:
! 25: The xdm update may cause build failure due to xdm.man being
! 26: in the obj tree. Make sure to ensure any like this:
! 27: nbmake: nbmake: don't know how to make xdm.man. Stop
! 28: is fixed by deleting the xdm.man in the obj tree.
! 29:
! 30: 20130530:
! 31: Updates of many xsrc packages will leave old .pc files around.
! 32: Best to clean out the xsrc objdir entirely before rebuilds.
! 33:
! 34: 20130301:
! 35: The removal of netiso requires manual removal of /usr/include/netiso
! 36: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
! 37:
1.238 dholland 38: 20120726:
1.238.2.1 tls 39: The update of OpenSSL requires cleaning both the OpenSSL build
40: directory and DESTDIR. *Even non-update builds require cleaning
41: DESTDIR.* Builds done without taking these steps may fail, or in
42: some cases may succeed and install broken OpenSSL libraries that
43: cause third-party software to link incorrectly and/or crash.
1.238 dholland 44:
1.237 wiz 45: 20120507:
1.238.2.1 tls 46: The database schema for makemandb was changed. You will
1.237 wiz 47: need to update the database using 'makemandb -f' or wait
48: for the next weekly run to fix it.
49:
1.236 bsh 50: 20120319:
51: sys/conf/Makefile.kern.inc has been modified to adjust the
52: size of db_symtab automatically. You need to update dbsym in
53: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
54: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
55: mk.conf.
56:
1.235 joerg 57: 20120216:
1.238.2.1 tls 58: Default for MKCATPAGES changed to NO. Update builds will fail
59: unless DESTDIR is cleaned manually. If you built between 20120207
60: and 20120216, daily and weekly could have created an unreadable
61: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 62: the next run of weekly will fix it.
1.233 joerg 63:
1.232 christos 64: 20111227:
65: If you built between 20111225 and 20111227 you need to remove
66: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
67: bump has been reverted.
68:
1.231 tls 69: 20111125:
70: The "rnd" pseudodevice has been added to sys/conf/std, which
71: means it should no longer be explicitly listed in kernel
72: configuration files. The line "pseudo-device rnd" should be
73: removed from any custom kernel config files users may have.
74:
1.230 tls 75: 20111119:
76: A problem with the datastructures used by the rndctl(8)
77: utility (pointers in datastructures in an array, making 32->64
78: bit compatibility very painful) has been fixed in a
79: non-backwards-compatible way. If you replace your kernel,
80: replace your rndctl executable too.
1.238.2.1 tls 81:
1.229 jym 82: 20111001:
83: the prop_*_send_syscall() functions from proplib(3) have been
84: changed and their new version is not backward compatible with the old
1.238.2.1 tls 85: one. So ensure that all consumers of these functions (currently:
1.229 jym 86: quota2 code and its tests) are updated together with the new lib.
87:
1.228 mrg 88: 20110817:
89: sparc has been changed to use GCC 4.5.3, so any objdir or
90: DESTDIR for them should be deleted before updating.
91:
1.227 riastrad 92: 20110806:
93: i386 and amd64 have been changed to use GCC 4.5.3, so any
94: objdir or DESTDIR for them should be deleted before updating.
95:
1.226 mrg 96: 20110805:
97: The update to GCC 4.5.3 requires a non-trivial portion of
98: the tree to be cleaned. Best to delete both objdir and
99: DESTDIR before running this update. So far, only the
100: sparc64, mips and powerpc platforms have changed.
101:
1.225 matt 102: 20110803:
1.238.2.1 tls 103: The layout of external/public-domain/xz has changed. To do an
1.225 matt 104: update build you will have to remove the contents of the OBJDIR
105: for external/public-domain/xz/bin by hand as the xz entry there
106: is now a directory.
107:
1.223 joerg 108: 20110410:
1.238.2.1 tls 109: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 110: update build you have to clean both tools/binutils and
111: tools/gcc by hand.
1.223 joerg 112:
1.222 plunky 113: 20110328:
114: Building the Xorg binary was moved into a subdirectory to fix
1.238.2.1 tls 115: ordering issues with "make all". It may be necessary to remove
1.222 plunky 116: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
117: if your update build fails, as the "Xorg" entry there is now a
118: directory.
119:
1.220 joerg 120: 20110121:
1.221 lukem 121: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 122: the build of individual parts of the tree. This is handled
123: correctly by build.sh. Manual builds have to update /usr/share/mk
124: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 125:
1.217 jruoho 126: 20101217:
127: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.238.2.1 tls 128: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 129: group(5) in order to make the program work with existing setups.
130:
1.216 christos 131: 20101125:
132: The latest changes to setenv(3) dissallow setting environment
1.238.2.1 tls 133: variables with names that contain '='. Revision 1.18 of env.c
134: assumed that this was allowed. Installing a new libc with an
1.216 christos 135: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
136: break which affects the autoconf tests for dependency finding,
137: so building gcc will end up printing:
138: checking dependency style of gcc... none
139: configure: error: no usable dependency style found
140: Fix it by rebuilding and re-installing env.
1.138 lukem 141:
1.215 mrg 142: 20101119:
143: Recent Xorg updates in xsrc/external/mit/ may cause various build
144: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
145: have any build problems with xsrc, or problems with mismatched
146: versions between xorg-server and drivers.
147:
1.213 jmmv 148: 20100604:
149: The update of ATF to 0.9 causes old tests written in shell to fail
150: unless they are rebuilt. If you are building with MKUPDATE=yes,
151: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
152: trees by hand.
153:
1.211 tnozaki 154: 20100522:
1.212 mrg 155: Recent Xorg updates in xsrc/external/mit/ will cause various build
156: problems. Delete your entire DESTDIR and OBJDIR if you have any
157: build problems with xsrc.
158:
159: 20100522:
1.211 tnozaki 160: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 161: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 162:
1.210 christos 163: 20100520:
1.238.2.1 tls 164: The location of the xkb compiled descriptions has changed. Please
1.210 christos 165: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
166:
1.209 njoly 167: 20100222:
168: The shared objects file extension has been changed from .so to
169: .pico, in order to avoid conflicts with shared libraries names
170: libXX.so. All now stale regular .so files can be removed from
171: your object directories.
172:
1.208 roy 173: 20100204:
174: The termcap database has been removed from the sources,
175: but has not been marked obsolete so it is not removed
176: from the system when upgrading.
177: As such, you will need to remove them from your object
178: and destination directories.
179:
1.203 dyoung 180: 20091101:
1.205 dholland 181: After updating, it may be necessary to make the 'cleandir'
182: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
183: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
184: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 185:
1.202 mrg 186: 20091001:
1.206 dholland 187: On amd64 you must rebuild tools (to get the new binutils)
188: before building a kernel, or the build fails on cpufunc.S.
189:
190: 20091001:
1.202 mrg 191: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
192: symlink, failing the build. Delete the link, and the subdir
193: it is in, and retry your build.
194:
1.201 dsl 195: 20090718:
196: libc build changed so that strchr() provides the extra entry
1.238.2.1 tls 197: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 198: may fail because the archive contains the unwanted index.o.
199: (Similarly for strrchr() and rindex().)
200:
1.198 mrg 201: 20090709:
202: Native Xorg was upgraded again. Builds will probably fail again
203: without a clean objdir, at least for src/external/mit/xorg.
204:
1.197 mrg 205: 20090616:
206: Native Xorg was upgraded. Builds will need a clean objdir for
207: src/external/mit/xorg. Upgrading a system from sets will not
208: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
209: subdirectory has been changed into a file, and this needs to
210: be manually "rm -r"'ed before installing xbase.tgz.
211:
1.195 perry 212: 20090501:
213: Several new functions were added to string.h/libc, and this
214: can cause autoconf problems during the tool build for people
1.238.2.1 tls 215: who fail to clean out their tools objects properly. If you
1.195 perry 216: note messages about stpcpy, stpncpy or strnlen accompanying a
217: failure during the tool build, clean out all your tools
218: objects and start again.
219:
1.194 mrg 220: 20090325:
221: The i386 port was switched to i486 default toolchain. This requires
222: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
223:
1.192 skrll 224: 20090126:
1.238.2.1 tls 225: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 226: need to 'rm -f __posix_fadvise50.*' in the libc build directory
227: to avoid using the old assembly stub.
1.192 skrll 228:
1.191 joerg 229: 20090202:
230: pkg_install now depends on the pkgdb cache for automatic conflict
231: detection. It is recommented to rebuild the cache with
232: ``pkg_admin rebuild''.
233:
1.184 christos 234: 20090110:
1.238.2.1 tls 235: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
236: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 237: This is needed even in the MODULAR kernel because there is
238: conditionally compiled code in rtsock.c.
1.184 christos 239: 2. make sure build.sh completes and the binaries in a chroot work
240: before installing.
241: 3. If you don't use build.sh and you build directly to root, and
1.238.2.1 tls 242: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 243: are installed properly, and start building libraries first libc
244: and libutil, install them and then continue building all the
1.238.2.1 tls 245: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 246: the new libraries are installed, you can restart the build.
247: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 248: rebuild the required packages to update their shared libraries.
249: Any package you rebuild will require rebuilding all the packages
250: that depend on it.
1.186 christos 251: 5. Next time you run pwd_mkdb with the new binary, the file
252: will be upgraded and it will not be backwards compatible.
1.190 apb 253: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
254: lastlogx(5)) have been versioned, and there is a heuristic
1.238.2.1 tls 255: for utmp. You are better off removing the old files after
1.190 apb 256: upgrading. The automated clearing of /var/run during
257: boot, and the automated rotating of files in /var/log by
258: newsyslog(8), may mean that you do not have to remove the
259: files manually.
260: 7. The optional accounting file (/var/account/acct, see
261: accton(8)) has not been versioned, and will need to be
262: removed. The automatic rotation of the accounting file by
263: /etc/daily limits the bad consequences of failure to remove
264: the file.
1.196 dholland 265: 8. Application software that writes time_t to binary files on
1.238.2.1 tls 266: disk will break or need attention. Most notably: if you are
1.196 dholland 267: using PostgreSQL < 8.4, you need to dump your databases,
268: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 269:
1.183 pgoyette 270: 20081219:
271: config(1) has been updated, and one of the files it creates -
272: swapnetbsd.o - has changed format. You need to rebuild config
273: (done automatically by build.sh) and then you need to rerun
274: config on all kernel configuration files before rebuilding those
275: kernels.
276:
1.181 cube 277: 20081205:
278: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
279: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
280: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 281:
1.179 tsutsui 282: 20081122:
1.182 tsutsui 283: On i386, various kernel options(4) in GENERIC including
1.180 wiz 284: file systems have been disabled and moved into kernel modules.
285: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 286: following files as well as a new GENERIC kernel:
287:
288: - build and install kernel modules from src/sys/modules
289:
290: - install the latest bootloader, which will load a module
1.180 wiz 291: for the file system from which the kernel is loaded automatically
1.179 tsutsui 292:
1.180 wiz 293: If you have to load your kernel from a file system which is not of
294: the same type as the root file system, you have to load the necessary
295: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 296:
1.178 lukem 297: 20080827:
298: If you built and installed a libc from sources between
299: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
300: which results in false errors reported by lint(1).
301: Since this breaks the libc build itself, manual help is
1.180 wiz 302: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 303: $ (cd lib/libc && make MKLINT=no dependall install)
304:
1.177 christos 305: 20080813:
306: MKDEBUG build was broken because the .depend files did not know
1.238.2.1 tls 307: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 308:
1.200 dholland 309: 20080802:
310: A regression in binary compatibility for pthread_mutex_t has
1.238.2.1 tls 311: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 312: for -current.
313:
314: Threaded programs (using libpthread) and C++ programs (using
315: libstdc++) compiled after 20070907 and before 20080802 need to
316: be recompiled.
317:
318: One way to find affected pkgsrc packages:
319:
320: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
321: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
322:
1.175 simonb 323: 20080731:
324: WAPBL (metadata journaling support) has been added, but at this
325: time isn't backwards compatible with pre-WAPBL aware kernels
326: and userland (fsck_ffs in particular). Please make sure you
327: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 328: especially an uncleanly mounted journaled filesystem. WAPBL
329: also requires the super block to be in the UFS2 format. You
330: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 331:
1.174 lukem 332: 20080721:
333: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
334: isn't defined.
335:
1.173 freza 336: 20080531:
1.238.2.1 tls 337: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
338: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 339: utility needs to be rebuilt and reinstalled as older binaries
1.238.2.1 tls 340: won't work correctly. The following sequence of commands:
1.173 freza 341:
342: $ (cd sys/sys/ && nbmake-$arch includes)
343: $ (cd sbin/drvctl/ && nbmake-$arch clean)
344: $ (cd sbin/drvctl/ && nbmake-$arch all)
345:
346: leaves new drvctl utility in sbin/drvctl build directory.
347:
1.172 lukem 348: 20080503:
349: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
350:
1.171 he 351: 20080521:
352: For a while, unprivileged UPDATE builds would fail to
353: succeed at the checkflist stage, complaining that
354: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
355: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
356: If you already hit this problem, update the .mk file,
357: remove ${DESTDIR}/stand/<arch>, and re-run the build.
358:
1.174 lukem 359: 20080303:
360: Linker warnings are now fatal if $WARNS>0.
361:
1.170 christos 362: 20080126:
363: The posix_fadvise system call has been changed from an assembly
1.238.2.1 tls 364: stub, to a c file that calls an assembly stub. You need to
1.170 christos 365: 'rm -f posix_fadvise.* .depend' in the libc build directory to
366: avoid using the old assembly stub.
367:
1.168 joerg 368: 20071209:
1.238.2.1 tls 369: The acpiec(4) driver has been split into two attachments. If you
1.168 joerg 370: get ACPI errors before the attachment, please update your kernel
1.169 wiz 371: configuration file appropriately or see GENERIC for more details.
1.168 joerg 372:
1.166 xtraeme 373: 20071115:
374: The it(4) driver has been renamed to itesio(4) and the old port
375: argument specified in the kernel configuration file is not valid
1.238.2.1 tls 376: anymore. The itesio(4) driver now uses the Super I/O address port
377: rather than the EC address port. Please update your kernel
1.167 wiz 378: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 379:
1.165 jmmv 380: 20071028:
381: The pccons(4) driver has been removed from the NetBSD/shark port.
382: You need to update any custom kernel configuration file you have
383: to remove any references to pccons (which includes removing the
384: now useless XSERVER option) and replace them with the correct
385: entries for the wscons driver. See the GENERIC configuration file
386: for more details.
387:
1.164 gdt 388: 20070913:
389: A latent bug in dhclient/dhcpd that caused it to be unable to
390: enumerate interfaces was fixed. The bug began to cause

406: has been changed. Rather than modify the pathname (and copy back
407: to userspace) namei() and lookup() directly check the emulation
1.238.2.1 tls 408: root. One side effect is that absolute symlinks inside the emulated

1.1 abs 484: Hints for a more successful build:
485: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 486: Use build.sh, but do not use its "expert mode":
1.132 jmmv 487: This will automatically build the tools in the
1.123 jmc 488: correct order, and it will keep the tools and the
489: new build products from interfering with the running
490: system. This will allow you to ignore most of the
491: other advice in this file.
1.2 mrg 492: Build a new kernel first:
493: This makes sure that any new system calls or features
494: expected by the new userland will be present. This
495: helps to avoid critical errors when upgrading.
1.1 abs 496: Use object directories:
497: This helps to keep stale object
498: files from polluting the build if a Makefile "forgets"
499: about one. It also makes it easier to clean up after
500: a build. It's also necessary if you want to use the
501: same source tree for multiple machines.
1.123 jmc 502: To use object directories with build.sh:
503: a) invoke build.sh with the "-M" or "-O" options.
504: To use object directories without using build.sh:
1.1 abs 505: a) cd /usr/src ; make cleandir
1.2 mrg 506: b) Add "OBJMACHINE=yes" to /etc/mk.conf
507: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 508: d) cd /usr/src ; make build
1.2 mrg 509: Note that running "make obj" in a directory will create
510: in obj.$MACHINE directory.
1.1 abs 511: Build to a DESTDIR:
1.123 jmc 512: This helps to keep old installed files (especially libraries)
513: from interfering with the new build.
514: To build to a DESTDIR with build.sh, use the "-D" option.
515: To build to a DESTDIR without using build.sh, set the DESTDIR
516: environment variable before running make build. It should be
517: set to the pathname of an initially empty directory.
518: Problems: if you do not use build.sh, you might need to
519: update critical utilities without using DESTDIR since
520: nothing is executed from what is installed in DESTDIR.
521: (See critical utils, below.)
1.1 abs 522: Build often:
523: This keeps critical utilities current enough to not choke
524: on any other part of the source tree that depends on up to
1.123 jmc 525: date functionality. If you use build.sh, you should not have
526: this problem.

529: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 530: When things don't work there are usually a few things that commonly
1.1 abs 531: should be done.
532: 1) make includes
533: This should be done automatically by make build.
534: 2) cd share/mk && make install
535: Again, automatically done by make build.
536:
537: Failsafe rebuild of a small part of the tree:
538: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
539: To make sure you rebuild something correctly you want to do
540: something like the following:
541: 1) Make sure the includes and .mk files are up to date.
542: 2) Make sure any program used to build the particular
543: utility is up to date. (yacc, lex, etc...)
544: 3) cd ...path/to/util...
545: make cleandir
546: rm ...all obj directories...
547: make cleandir # yes, again
548: make obj
549: make depend && make
550:
551: Failsafe rebuild of the entire tree:
552: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
553: If you really want to make sure the source tree is clean and
1.2 mrg 554: ready for a build try the following. Note that sourcing /etc/mk.conf
555: (a make(1) Makefile) in this manner is not right, and will not work
