1.226 ! mrg 1: $NetBSD: UPDATING,v 1.225 2011/08/04 03:48:11 matt 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.

16: Recent changes:
17: ^^^^^^^^^^^^^^^
1.226 ! mrg 18: 20110805:
! 19: The update to GCC 4.5.3 requires a non-trivial portion of
! 20: the tree to be cleaned. Best to delete both objdir and
! 21: DESTDIR before running this update. So far, only the
! 22: sparc64, mips and powerpc platforms have changed.
! 23:
1.225 matt 24: 20110803:
25: The layout of external/public-domain/xz has changed. To do an
26: update build you will have to remove the contents of the OBJDIR
27: for external/public-domain/xz/bin by hand as the xz entry there
28: is now a directory.
29:
1.223 joerg 30: 20110410:
1.224 dholland 31: The configuration of src/tools/gcc has changed. To do an
32: update build you have to clean both tools/binutils and
33: tools/gcc by hand.
1.223 joerg 34:
1.222 plunky 35: 20110328:
36: Building the Xorg binary was moved into a subdirectory to fix
37: ordering issues with "make all". It may be necessary to remove
38: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
39: if your update build fails, as the "Xorg" entry there is now a
40: directory.
41:
1.220 joerg 42: 20110121:
1.221 lukem 43: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 44: the build of individual parts of the tree. This is handled
45: correctly by build.sh. Manual builds have to update /usr/share/mk
46: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 47:
1.217 jruoho 48: 20101217:
49: The tcpdump(8) program was changed to drop privileges and chroot(2)
50: by default. It may be necessary to manually update passwd(5) and
51: group(5) in order to make the program work with existing setups.
52:
1.216 christos 53: 20101125:
54: The latest changes to setenv(3) dissallow setting environment
55: variables with names that contain '='. Revision 1.18 of env.c
56: assumed that this was allowed. Installing a new libc with an
57: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
58: break which affects the autoconf tests for dependency finding,
59: so building gcc will end up printing:
60: checking dependency style of gcc... none
61: configure: error: no usable dependency style found
62: Fix it by rebuilding and re-installing env.
1.138 lukem 63:
1.215 mrg 64: 20101119:
65: Recent Xorg updates in xsrc/external/mit/ may cause various build
66: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
67: have any build problems with xsrc, or problems with mismatched
68: versions between xorg-server and drivers.
69:
1.213 jmmv 70: 20100604:
71: The update of ATF to 0.9 causes old tests written in shell to fail
72: unless they are rebuilt. If you are building with MKUPDATE=yes,
73: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
74: trees by hand.
75:
1.211 tnozaki 76: 20100522:
1.212 mrg 77: Recent Xorg updates in xsrc/external/mit/ will cause various build
78: problems. Delete your entire DESTDIR and OBJDIR if you have any
79: build problems with xsrc.
80:
81: 20100522:
1.211 tnozaki 82: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 83: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 84:
1.210 christos 85: 20100520:
86: The location of the xkb compiled descriptions has changed. Please
87: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
88:
1.209 njoly 89: 20100222:
90: The shared objects file extension has been changed from .so to
91: .pico, in order to avoid conflicts with shared libraries names
92: libXX.so. All now stale regular .so files can be removed from
93: your object directories.
94:
1.208 roy 95: 20100204:
96: The termcap database has been removed from the sources,
97: but has not been marked obsolete so it is not removed
98: from the system when upgrading.
99: As such, you will need to remove them from your object
100: and destination directories.
101:
1.203 dyoung 102: 20091101:
1.205 dholland 103: After updating, it may be necessary to make the 'cleandir'
104: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
105: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
106: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 107:
1.202 mrg 108: 20091001:
1.206 dholland 109: On amd64 you must rebuild tools (to get the new binutils)
110: before building a kernel, or the build fails on cpufunc.S.
111:
112: 20091001:
1.202 mrg 113: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
114: symlink, failing the build. Delete the link, and the subdir
115: it is in, and retry your build.
116:
1.201 dsl 117: 20090718:
118: libc build changed so that strchr() provides the extra entry
119: point for index(). Update build of libc.a (and libc_pic.a)
120: may fail because the archive contains the unwanted index.o.
121: (Similarly for strrchr() and rindex().)
122:
1.198 mrg 123: 20090709:
124: Native Xorg was upgraded again. Builds will probably fail again
125: without a clean objdir, at least for src/external/mit/xorg.
126:
1.197 mrg 127: 20090616:
128: Native Xorg was upgraded. Builds will need a clean objdir for
129: src/external/mit/xorg. Upgrading a system from sets will not
130: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
131: subdirectory has been changed into a file, and this needs to
132: be manually "rm -r"'ed before installing xbase.tgz.
133:
1.195 perry 134: 20090501:
135: Several new functions were added to string.h/libc, and this
136: can cause autoconf problems during the tool build for people
137: who fail to clean out their tools objects properly. If you
138: note messages about stpcpy, stpncpy or strnlen accompanying a
139: failure during the tool build, clean out all your tools
140: objects and start again.
141:
1.194 mrg 142: 20090325:
143: The i386 port was switched to i486 default toolchain. This requires
144: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
145:
1.192 skrll 146: 20090126:
1.207 mbalmer 147: The __posix_fadvise50 system call changed assembly stub type. You
148: need to 'rm -f __posix_fadvise50.*' in the libc build directory
149: to avoid using the old assembly stub.
1.192 skrll 150:
1.191 joerg 151: 20090202:
152: pkg_install now depends on the pkgdb cache for automatic conflict
153: detection. It is recommented to rebuild the cache with
154: ``pkg_admin rebuild''.
155:
1.184 christos 156: 20090110:
157: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
158: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 159: This is needed even in the MODULAR kernel because there is
160: conditionally compiled code in rtsock.c.
1.184 christos 161: 2. make sure build.sh completes and the binaries in a chroot work
162: before installing.
163: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 164: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 165: are installed properly, and start building libraries first libc
166: and libutil, install them and then continue building all the
167: libraries in src/lib and src/gnu/lib and install them. Once
168: the new libraries are installed, you can restart the build.
169: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 170: rebuild the required packages to update their shared libraries.
171: Any package you rebuild will require rebuilding all the packages
172: that depend on it.
1.186 christos 173: 5. Next time you run pwd_mkdb with the new binary, the file
174: will be upgraded and it will not be backwards compatible.
1.190 apb 175: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
176: lastlogx(5)) have been versioned, and there is a heuristic
177: for utmp. You are better off removing the old files after
178: upgrading. The automated clearing of /var/run during
179: boot, and the automated rotating of files in /var/log by
180: newsyslog(8), may mean that you do not have to remove the
181: files manually.
182: 7. The optional accounting file (/var/account/acct, see
183: accton(8)) has not been versioned, and will need to be
184: removed. The automatic rotation of the accounting file by
185: /etc/daily limits the bad consequences of failure to remove
186: the file.
1.196 dholland 187: 8. Application software that writes time_t to binary files on
188: disk will break or need attention. Most notably: if you are
189: using PostgreSQL < 8.4, you need to dump your databases,
190: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 191:
1.183 pgoyette 192: 20081219:
193: config(1) has been updated, and one of the files it creates -
194: swapnetbsd.o - has changed format. You need to rebuild config
195: (done automatically by build.sh) and then you need to rerun
196: config on all kernel configuration files before rebuilding those
197: kernels.
198:
1.181 cube 199: 20081205:
200: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
201: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
202: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 203:
1.179 tsutsui 204: 20081122:
1.182 tsutsui 205: On i386, various kernel options(4) in GENERIC including
1.180 wiz 206: file systems have been disabled and moved into kernel modules.
207: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 208: following files as well as a new GENERIC kernel:
209:
210: - build and install kernel modules from src/sys/modules
211:
212: - install the latest bootloader, which will load a module
1.180 wiz 213: for the file system from which the kernel is loaded automatically
1.179 tsutsui 214:
1.180 wiz 215: If you have to load your kernel from a file system which is not of
216: the same type as the root file system, you have to load the necessary
217: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 218:
1.178 lukem 219: 20080827:
220: If you built and installed a libc from sources between
221: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
222: which results in false errors reported by lint(1).
223: Since this breaks the libc build itself, manual help is
1.180 wiz 224: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 225: $ (cd lib/libc && make MKLINT=no dependall install)
226:
1.177 christos 227: 20080813:
228: MKDEBUG build was broken because the .depend files did not know
229: about .go files. You need to remove all .depend files and rebuild.
230:
1.200 dholland 231: 20080802:
232: A regression in binary compatibility for pthread_mutex_t has
233: been fixed. Unfortunately, the price is breaking compatibility
234: for -current.
235:
236: Threaded programs (using libpthread) and C++ programs (using
237: libstdc++) compiled after 20070907 and before 20080802 need to
238: be recompiled.
239:
240: One way to find affected pkgsrc packages:
241:
242: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
243: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
244:
1.175 simonb 245: 20080731:
246: WAPBL (metadata journaling support) has been added, but at this
247: time isn't backwards compatible with pre-WAPBL aware kernels
248: and userland (fsck_ffs in particular). Please make sure you
249: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 250: especially an uncleanly mounted journaled filesystem. WAPBL
251: also requires the super block to be in the UFS2 format. You
252: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 253:
1.174 lukem 254: 20080721:
255: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
256: isn't defined.
257:
1.173 freza 258: 20080531:
259: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
260: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
261: utility needs to be rebuilt and reinstalled as older binaries
262: won't work correctly. The following sequence of commands:
263:
264: $ (cd sys/sys/ && nbmake-$arch includes)
265: $ (cd sbin/drvctl/ && nbmake-$arch clean)
266: $ (cd sbin/drvctl/ && nbmake-$arch all)
267:
268: leaves new drvctl utility in sbin/drvctl build directory.
269:
1.172 lukem 270: 20080503:
271: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
272:
1.171 he 273: 20080521:
274: For a while, unprivileged UPDATE builds would fail to
275: succeed at the checkflist stage, complaining that
276: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
277: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
278: If you already hit this problem, update the .mk file,
279: remove ${DESTDIR}/stand/<arch>, and re-run the build.
280:
1.174 lukem 281: 20080303:
282: Linker warnings are now fatal if $WARNS>0.
283:
1.170 christos 284: 20080126:
285: The posix_fadvise system call has been changed from an assembly
286: stub, to a c file that calls an assembly stub. You need to
287: 'rm -f posix_fadvise.* .depend' in the libc build directory to
288: avoid using the old assembly stub.
289:
1.168 joerg 290: 20071209:
291: The acpiec(4) driver has been split into two attachments. If you
292: get ACPI errors before the attachment, please update your kernel
1.169 wiz 293: configuration file appropriately or see GENERIC for more details.
1.168 joerg 294:
1.166 xtraeme 295: 20071115:
296: The it(4) driver has been renamed to itesio(4) and the old port
297: argument specified in the kernel configuration file is not valid
298: anymore. The itesio(4) driver now uses the Super I/O address port
299: rather than the EC address port. Please update your kernel
1.167 wiz 300: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 301:
1.165 jmmv 302: 20071028:
303: The pccons(4) driver has been removed from the NetBSD/shark port.
304: You need to update any custom kernel configuration file you have
305: to remove any references to pccons (which includes removing the
306: now useless XSERVER option) and replace them with the correct
307: entries for the wscons driver. See the GENERIC configuration file
308: for more details.
309:
1.164 gdt 310: 20070913:
311: A latent bug in dhclient/dhcpd that caused it to be unable to
312: enumerate interfaces was fixed. The bug began to cause
313: problems after 20070911 when the kernel's SIOCGIFCONF
314: implementation was repaired. From 20070529 to 20070911 racoon
315: could not enumerate interfaces. (These are noted because
316: normal kernel/userspace version matching hygiene is not
317: sufficient to avoid this problem.) Ensure that both kernel
318: and userland are from after 20070913.
319:
1.163 joerg 320: 20070703:
1.199 dholland 321: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
322: calls the target-specific strip program, and the logic to pass
323: down STRIP from make has been removed. This requires a
324: re-installation of tools.
1.163 joerg 325:
1.161 dsl 326: 20070422:
327: The way OS emulations lookup filenames inside the emulation root
328: has been changed. Rather than modify the pathname (and copy back
329: to userspace) namei() and lookup() directly check the emulation
330: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 331: root file system will be relative to that file system - unless they
1.161 dsl 332: start /../ this is useful when the emulated root is a real install
333: that has such links.
334: This might affect symlinks that have been added to reference outside
335: the emulated root.
336:
1.160 jmcneill 337: 20070412:
338: The pckbc driver on sgimips IP32 has been removed. Use macekbc
339: instead. See the GENERIC32_IP3x kernel configuration for an
340: example.
341:
1.159 gdt 342: 20070319:
343: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
344: on many platforms due to incorrect flags settings. If you
345: updated and built after about 20070315, do "nbmake-$arch
346: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
347: rebuild of object files that might have been built
348: incorrectly, and ensure that you have at least
349: src/lib/libc/Makefile 1.130.
350:
1.158 dbj 351: 20070210:
352: src/sys/sys/{sa.h,savar.h} were removed.
353: find ${OBJDIR} $ -name .depend -o -name '*.d' $ -print \
354: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
355: will allow dependencies on those files to get get rebuilt
356:
1.157 apb 357: 20070209:
358: The threading model was changed when the newlock2 branch
359: was merged to NetBSD-current. If you boot with a new
360: kernel (version 4.99.10), then you also need a new pthread
361: library (/usr/lib/libpthread.so.0.7). If you boot with
362: an old kernel, then you need the old pthread library
363: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
364: the pthread library in sync, old threaded applications should
365: continue to work with an old or new kernel. Note that named(8)
366: is the only threaded application in the base system.
367:
1.154 he 368: 20061214:
369: Following the move of string_to_flags() and flags_to_string()
370: from the bin/ls/ sources to libutil, users doing UPDATE builds
371: will need to do a "make cleandir" in
372: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
373: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 374: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
375: as the installation images in distrib/
1.154 he 376: in order to excise stale references to the old stat_flags.h header
377: file in the ls sources -- stat_flags.h has been removed.
378:
1.152 christos 379: 20061108:
380: The configure script used in the src/tools/gcc compiler has been
381: changed to indicate that our libc has ssp support built-in and
382: does not depend on -lssp and -lssp-nonshared. You'll need to
383: make clean in src/tools/gcc first to rebuild the compiler.
384:
1.151 rpaulo 385: 20061009:
386: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
387: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
388:
1.150 bjh21 389: 20060814:
390: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
391: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
392: kernel configuration for an example. X servers from the last
393: few years should cope.
394:
1.149 christos 395: 20060703:
396: MPACPI is no more. We always configure PCI interrupts using ACPI
397: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
398: to ACPI_SCANPCI. Thanks to work from fvdl.
399:
1.148 dogcow 400: 20060627:
401: socket(2) has changed, and its system call has been versioned.
402: For userlands with the old version of socket(2), make sure that
403: your kernel has 'options COMPAT_30' set, or else 'bad system call'
404: errors will result.
405:
1.1 abs 406: Hints for a more successful build:
407: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 408: Use build.sh, but do not use its "expert mode":
1.132 jmmv 409: This will automatically build the tools in the
1.123 jmc 410: correct order, and it will keep the tools and the
411: new build products from interfering with the running
412: system. This will allow you to ignore most of the
413: other advice in this file.
1.2 mrg 414: Build a new kernel first:
415: This makes sure that any new system calls or features
416: expected by the new userland will be present. This
417: helps to avoid critical errors when upgrading.
1.1 abs 418: Use object directories:
419: This helps to keep stale object
420: files from polluting the build if a Makefile "forgets"
421: about one. It also makes it easier to clean up after
422: a build. It's also necessary if you want to use the
423: same source tree for multiple machines.
1.123 jmc 424: To use object directories with build.sh:
425: a) invoke build.sh with the "-M" or "-O" options.
426: To use object directories without using build.sh:
1.1 abs 427: a) cd /usr/src ; make cleandir
1.2 mrg 428: b) Add "OBJMACHINE=yes" to /etc/mk.conf
429: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 430: d) cd /usr/src ; make build
1.2 mrg 431: Note that running "make obj" in a directory will create
432: in obj.$MACHINE directory.
1.1 abs 433: Build to a DESTDIR:
1.123 jmc 434: This helps to keep old installed files (especially libraries)
435: from interfering with the new build.
436: To build to a DESTDIR with build.sh, use the "-D" option.
437: To build to a DESTDIR without using build.sh, set the DESTDIR
438: environment variable before running make build. It should be
439: set to the pathname of an initially empty directory.
440: Problems: if you do not use build.sh, you might need to
441: update critical utilities without using DESTDIR since
442: nothing is executed from what is installed in DESTDIR.
443: (See critical utils, below.)
1.1 abs 444: Build often:
445: This keeps critical utilities current enough to not choke
446: on any other part of the source tree that depends on up to
1.123 jmc 447: date functionality. If you use build.sh, you should not have
448: this problem.
1.1 abs 449:
450: What to do if things don't work:
451: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
452: When things don't work there is usually a few things that commonly
453: should be done.
454: 1) make includes
455: This should be done automatically by make build.
456: 2) cd share/mk && make install
457: Again, automatically done by make build.
458:
459: Failsafe rebuild of a small part of the tree:
460: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
461: To make sure you rebuild something correctly you want to do
462: something like the following:
463: 1) Make sure the includes and .mk files are up to date.
464: 2) Make sure any program used to build the particular
465: utility is up to date. (yacc, lex, etc...)
466: 3) cd ...path/to/util...
467: make cleandir
468: rm ...all obj directories...
469: make cleandir # yes, again
470: make obj
471: make depend && make
472:
473: Failsafe rebuild of the entire tree:
474: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
475: If you really want to make sure the source tree is clean and
1.2 mrg 476: ready for a build try the following. Note that sourcing /etc/mk.conf
477: (a make(1) Makefile) in this manner is not right, and will not work
478: for anyone who uses any make(1) features in /etc/mk.conf.
