1 $NetBSD: UPDATING,v 1.201 2009/07/18 09:50:32 dsl Exp $
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.
7 For a more detailed description of the recommended way to build NetBSD
8 using build.sh, see the BUILDING file.
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.
14 See also: BUILDING, build.sh, Makefile.
20 An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
21 symlink, failing the build. Delete the link, and the subdir
22 it is in, and retry your build.
25 libc build changed so that strchr() provides the extra entry
26 point for index(). Update build of libc.a (and libc_pic.a)
27 may fail because the archive contains the unwanted index.o.
28 (Similarly for strrchr() and rindex().)
31 Native Xorg was upgraded again. Builds will probably fail again
32 without a clean objdir, at least for src/external/mit/xorg.
35 Native Xorg was upgraded. Builds will need a clean objdir for
36 src/external/mit/xorg. Upgrading a system from sets will not
37 work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
38 subdirectory has been changed into a file, and this needs to
39 be manually "rm -r"'ed before installing xbase.tgz.
42 Several new functions were added to string.h/libc, and this
43 can cause autoconf problems during the tool build for people
44 who fail to clean out their tools objects properly. If you
45 note messages about stpcpy, stpncpy or strnlen accompanying a
46 failure during the tool build, clean out all your tools
47 objects and start again.
50 The i386 port was switched to i486 default toolchain. This requires
51 cleaning your src/tools directory and $TOOLDIR and rebuilding them.
54 The __posix_fadvise50 system call changed assembly stub type. You need to
55 'rm -f __posix_fadvise50.*' in the libc build directory to avoid using
56 the old assembly stub.
59 pkg_install now depends on the pkgdb cache for automatic conflict
60 detection. It is recommented to rebuild the cache with
61 ``pkg_admin rebuild''.
64 time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
65 1. Make sure your kernel has COMPAT_50 in it. Build and install.
66 This is needed even in the MODULAR kernel because there is
67 conditionally compiled code in rtsock.c.
68 2. make sure build.sh completes and the binaries in a chroot work
70 3. If you don't use build.sh and you build directly to root, and
71 your build breaks in the middle, don't despair. Make sure headers
72 are installed properly, and start building libraries first libc
73 and libutil, install them and then continue building all the
74 libraries in src/lib and src/gnu/lib and install them. Once
75 the new libraries are installed, you can restart the build.
76 4. If you compile packages and you notice link time warnings,
77 rebuild the required packages to update their shared libraries.
78 Any package you rebuild will require rebuilding all the packages
80 5. Next time you run pwd_mkdb with the new binary, the file
81 will be upgraded and it will not be backwards compatible.
82 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
83 lastlogx(5)) have been versioned, and there is a heuristic
84 for utmp. You are better off removing the old files after
85 upgrading. The automated clearing of /var/run during
86 boot, and the automated rotating of files in /var/log by
87 newsyslog(8), may mean that you do not have to remove the
89 7. The optional accounting file (/var/account/acct, see
90 accton(8)) has not been versioned, and will need to be
91 removed. The automatic rotation of the accounting file by
92 /etc/daily limits the bad consequences of failure to remove
94 8. Application software that writes time_t to binary files on
95 disk will break or need attention. Most notably: if you are
96 using PostgreSQL < 8.4, you need to dump your databases,
97 rebuild PostgreSQL with the new time_t, then restore.
100 config(1) has been updated, and one of the files it creates -
101 swapnetbsd.o - has changed format. You need to rebuild config
102 (done automatically by build.sh) and then you need to rerun
103 config on all kernel configuration files before rebuilding those
107 If you build with MKX11=no, you should remove /etc/rc.d/xdm and
108 /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
109 set and will appear as extra files for MKX11=no update builds.
112 On i386, various kernel options(4) in GENERIC including
113 file systems have been disabled and moved into kernel modules.
114 Before trying a new GENERIC kernel, you have to prepare the
115 following files as well as a new GENERIC kernel:
117 - build and install kernel modules from src/sys/modules
119 - install the latest bootloader, which will load a module
120 for the file system from which the kernel is loaded automatically
122 If you have to load your kernel from a file system which is not of
123 the same type as the root file system, you have to load the necessary
124 file system module manually on the boot prompt or in the boot.cfg file.
127 If you built and installed a libc from sources between
128 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
129 which results in false errors reported by lint(1).
130 Since this breaks the libc build itself, manual help is
131 needed -- lint must be disabled temporarily, e.g.:
132 $ (cd lib/libc && make MKLINT=no dependall install)
135 MKDEBUG build was broken because the .depend files did not know
136 about .go files. You need to remove all .depend files and rebuild.
139 A regression in binary compatibility for pthread_mutex_t has
140 been fixed. Unfortunately, the price is breaking compatibility
143 Threaded programs (using libpthread) and C++ programs (using
144 libstdc++) compiled after 20070907 and before 20080802 need to
147 One way to find affected pkgsrc packages:
149 $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
150 $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
153 WAPBL (metadata journaling support) has been added, but at this
154 time isn't backwards compatible with pre-WAPBL aware kernels
155 and userland (fsck_ffs in particular). Please make sure you
156 don't use a journaled filesystem with an older kernel/userland,
157 especially an uncleanly mounted journaled filesystem. WAPBL
158 also requires the super block to be in the UFS2 format. You
159 can use fsck_ffs -c 4 to update the superblock format.
162 Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
166 The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
167 from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
168 utility needs to be rebuilt and reinstalled as older binaries
169 won't work correctly. The following sequence of commands:
171 $ (cd sys/sys/ && nbmake-$arch includes)
172 $ (cd sbin/drvctl/ && nbmake-$arch clean)
173 $ (cd sbin/drvctl/ && nbmake-$arch all)
175 leaves new drvctl utility in sbin/drvctl build directory.
178 The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
181 For a while, unprivileged UPDATE builds would fail to
182 succeed at the checkflist stage, complaining that
183 ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
184 problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
185 If you already hit this problem, update the .mk file,
186 remove ${DESTDIR}/stand/<arch>, and re-run the build.
189 Linker warnings are now fatal if $WARNS>0.
192 The posix_fadvise system call has been changed from an assembly
193 stub, to a c file that calls an assembly stub. You need to
194 'rm -f posix_fadvise.* .depend' in the libc build directory to
195 avoid using the old assembly stub.
198 The acpiec(4) driver has been split into two attachments. If you
199 get ACPI errors before the attachment, please update your kernel
200 configuration file appropriately or see GENERIC for more details.
203 The it(4) driver has been renamed to itesio(4) and the old port
204 argument specified in the kernel configuration file is not valid
205 anymore. The itesio(4) driver now uses the Super I/O address port
206 rather than the EC address port. Please update your kernel
207 configuration file appropriately or see GENERIC for more details.
210 The pccons(4) driver has been removed from the NetBSD/shark port.
211 You need to update any custom kernel configuration file you have
212 to remove any references to pccons (which includes removing the
213 now useless XSERVER option) and replace them with the correct
214 entries for the wscons driver. See the GENERIC configuration file
218 A latent bug in dhclient/dhcpd that caused it to be unable to
219 enumerate interfaces was fixed. The bug began to cause
220 problems after 20070911 when the kernel's SIOCGIFCONF
221 implementation was repaired. From 20070529 to 20070911 racoon
222 could not enumerate interfaces. (These are noted because
223 normal kernel/userspace version matching hygiene is not
224 sufficient to avoid this problem.) Ensure that both kernel
225 and userland are from after 20070913.
228 nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
229 calls the target-specific strip program, and the logic to pass
230 down STRIP from make has been removed. This requires a
231 re-installation of tools.
234 The way OS emulations lookup filenames inside the emulation root
235 has been changed. Rather than modify the pathname (and copy back
236 to userspace) namei() and lookup() directly check the emulation
237 root. One side effect is that absolute symlinks inside the emulated
238 root file system will be relative to that file system - unless they
239 start /../ this is useful when the emulated root is a real install
241 This might affect symlinks that have been added to reference outside
245 The pckbc driver on sgimips IP32 has been removed. Use macekbc
246 instead. See the GENERIC32_IP3x kernel configuration for an
250 src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
251 on many platforms due to incorrect flags settings. If you
252 updated and built after about 20070315, do "nbmake-$arch
253 cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
254 rebuild of object files that might have been built
255 incorrectly, and ensure that you have at least
256 src/lib/libc/Makefile 1.130.
259 src/sys/sys/{sa.h,savar.h} were removed.
260 find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
261 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
262 will allow dependencies on those files to get get rebuilt
265 The threading model was changed when the newlock2 branch
266 was merged to NetBSD-current. If you boot with a new
267 kernel (version 4.99.10), then you also need a new pthread
268 library (/usr/lib/libpthread.so.0.7). If you boot with
269 an old kernel, then you need the old pthread library
270 (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
271 the pthread library in sync, old threaded applications should
272 continue to work with an old or new kernel. Note that named(8)
273 is the only threaded application in the base system.
276 Following the move of string_to_flags() and flags_to_string()
277 from the bin/ls/ sources to libutil, users doing UPDATE builds
278 will need to do a "make cleandir" in
279 tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
280 bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
281 usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
282 as the installation images in distrib/
283 in order to excise stale references to the old stat_flags.h header
284 file in the ls sources -- stat_flags.h has been removed.
287 The configure script used in the src/tools/gcc compiler has been
288 changed to indicate that our libc has ssp support built-in and
289 does not depend on -lssp and -lssp-nonshared. You'll need to
290 make clean in src/tools/gcc first to rebuild the compiler.
293 The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
294 available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
297 The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
298 withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
299 kernel configuration for an example. X servers from the last
300 few years should cope.
303 MPACPI is no more. We always configure PCI interrupts using ACPI
304 if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
305 to ACPI_SCANPCI. Thanks to work from fvdl.
308 socket(2) has changed, and its system call has been versioned.
309 For userlands with the old version of socket(2), make sure that
310 your kernel has 'options COMPAT_30' set, or else 'bad system call'
313 Hints for a more successful build:
314 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
315 Use build.sh, but do not use its "expert mode":
316 This will automatically build the tools in the
317 correct order, and it will keep the tools and the
318 new build products from interfering with the running
319 system. This will allow you to ignore most of the
320 other advice in this file.
321 Build a new kernel first:
322 This makes sure that any new system calls or features
323 expected by the new userland will be present. This
324 helps to avoid critical errors when upgrading.
325 Use object directories:
326 This helps to keep stale object
327 files from polluting the build if a Makefile "forgets"
328 about one. It also makes it easier to clean up after
329 a build. It's also necessary if you want to use the
330 same source tree for multiple machines.
331 To use object directories with build.sh:
332 a) invoke build.sh with the "-M" or "-O" options.
333 To use object directories without using build.sh:
334 a) cd /usr/src ; make cleandir
335 b) Add "OBJMACHINE=yes" to /etc/mk.conf
336 c) Add "MKOBJDIRS=yes" to /etc/mk.conf
337 d) cd /usr/src ; make build
338 Note that running "make obj" in a directory will create
339 in obj.$MACHINE directory.
341 This helps to keep old installed files (especially libraries)
342 from interfering with the new build.
343 To build to a DESTDIR with build.sh, use the "-D" option.
344 To build to a DESTDIR without using build.sh, set the DESTDIR
345 environment variable before running make build. It should be
346 set to the pathname of an initially empty directory.
347 Problems: if you do not use build.sh, you might need to
348 update critical utilities without using DESTDIR since
349 nothing is executed from what is installed in DESTDIR.
350 (See critical utils, below.)
352 This keeps critical utilities current enough to not choke
353 on any other part of the source tree that depends on up to
354 date functionality. If you use build.sh, you should not have
357 What to do if things don't work:
358 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
359 When things don't work there is usually a few things that commonly
362 This should be done automatically by make build.
363 2) cd share/mk && make install
364 Again, automatically done by make build.
366 Failsafe rebuild of a small part of the tree:
367 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
368 To make sure you rebuild something correctly you want to do
369 something like the following:
370 1) Make sure the includes and .mk files are up to date.
371 2) Make sure any program used to build the particular
372 utility is up to date. (yacc, lex, etc...)
373 3) cd ...path/to/util...
375 rm ...all obj directories...
376 make cleandir # yes, again
380 Failsafe rebuild of the entire tree:
381 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
382 If you really want to make sure the source tree is clean and
383 ready for a build try the following. Note that sourcing /etc/mk.conf
384 (a make(1) Makefile) in this manner is not right, and will not work
385 for anyone who uses any make(1) features in /etc/mk.conf.
391 if [ -z $NETBSDSRCDIR ] ; then
392 NETBSDSRCDIR=/usr/src
394 if [ \! -d $NETBSDSRCDIR ] ; then
395 echo Unable to find sources
398 find $NETBSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;
400 if [ -z $BSDOBJDIR ] ; then
403 if [ -d $BSDOBJDIR ] ; then
407 cd $NETBSDSRCDIR && make cleandir
420 Other problems and possible solutions:
421 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
422 Symptom:Complaints involving a Makefile.
423 Fix: Rebuild usr.bin/make:
424 cd usr.bin/make && make && make install
425 Or, a failsafe method if that doesn't work:
426 cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
428 Fix: Make sure .mk files are up to date.
429 cd share/mk && make install
431 Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
432 Fix: Rebuild usr.bin/config
435 Fix: Rebuild usr.bin/yacc
438 Fix: Rebuild usr.bin/lex
441 Fix: rm /usr/lib/libbfd.a
443 Symptom:Obsolete intermediate files are used during compilation
444 Fix: Try the following sequence of commands in the directory in question.
445 make cleandir; rm `make print-objdir`; make cleandir; make obj
446 (If you built the tree without "make obj" in the past, obsolete files
447 may remain. The command tries to clean everything up)
449 Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
450 Fix: Rebuild and install usr.bin/menuc
452 Symptom:mklocale not found during build in share/locale/ctype
453 Fix: Build and install usr.bin/mklocale
455 Symptom:undefined reference to `__assert13' or `__unsetenv13'
456 Fix: Rebuild and install lib/libc
458 Symptom:usr.bin/config fails to build.
459 Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
461 Symptom:undefined reference to `getprogname' or `setprogname'
462 Fix: Rebuild and install lib/libc
464 Symptom:lint does not understand the '-X' option
465 Fix: May need to build & install libs with NOLINT=1 before rebuilding lint
