1.202 ! mrg 1: $NetBSD: UPDATING,v 1.201 2009/07/18 09:50:32 dsl 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.

1.202 ! mrg 19: 20091001:
! 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.
! 23:
1.201 dsl 24: 20090718:
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().)
29:
1.198 mrg 30: 20090709:
31: Native Xorg was upgraded again. Builds will probably fail again
32: without a clean objdir, at least for src/external/mit/xorg.
33:
1.197 mrg 34: 20090616:
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.
40:
1.195 perry 41: 20090501:
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.
48:
1.194 mrg 49: 20090325:
50: The i386 port was switched to i486 default toolchain. This requires
51: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
52:
1.192 skrll 53: 20090126:
1.193 skrll 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
1.192 skrll 56: the old assembly stub.
57:
1.191 joerg 58: 20090202:
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''.
62:
1.184 christos 63: 20090110:
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.
1.188 christos 66: This is needed even in the MODULAR kernel because there is
67: conditionally compiled code in rtsock.c.
1.184 christos 68: 2. make sure build.sh completes and the binaries in a chroot work
69: before installing.
70: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 71: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 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,
1.189 hubertf 77: rebuild the required packages to update their shared libraries.
78: Any package you rebuild will require rebuilding all the packages
79: that depend on it.
1.186 christos 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.
1.190 apb 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
88: files manually.
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
93: the file.
1.196 dholland 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.
1.185 jmcneill 98:
1.183 pgoyette 99: 20081219:
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
104: kernels.
105:
1.181 cube 106: 20081205:
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.
1.178 lukem 110:
1.179 tsutsui 111: 20081122:
1.182 tsutsui 112: On i386, various kernel options(4) in GENERIC including
1.180 wiz 113: file systems have been disabled and moved into kernel modules.
114: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 115: following files as well as a new GENERIC kernel:
116:
117: - build and install kernel modules from src/sys/modules
118:
119: - install the latest bootloader, which will load a module
1.180 wiz 120: for the file system from which the kernel is loaded automatically
1.179 tsutsui 121:
1.180 wiz 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.
1.179 tsutsui 125:
1.178 lukem 126: 20080827:
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
1.180 wiz 131: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 132: $ (cd lib/libc && make MKLINT=no dependall install)
133:
1.177 christos 134: 20080813:
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.
137:
1.200 dholland 138: 20080802:
139: A regression in binary compatibility for pthread_mutex_t has
140: been fixed. Unfortunately, the price is breaking compatibility
141: for -current.
142:
143: Threaded programs (using libpthread) and C++ programs (using
144: libstdc++) compiled after 20070907 and before 20080802 need to
145: be recompiled.
146:
147: One way to find affected pkgsrc packages:
148:
149: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
150: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
151:
1.175 simonb 152: 20080731:
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,
1.176 simonb 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.
1.175 simonb 160:
1.174 lukem 161: 20080721:
162: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
163: isn't defined.
164:
1.173 freza 165: 20080531:
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:
170:
171: $ (cd sys/sys/ && nbmake-$arch includes)
172: $ (cd sbin/drvctl/ && nbmake-$arch clean)
173: $ (cd sbin/drvctl/ && nbmake-$arch all)
174:
175: leaves new drvctl utility in sbin/drvctl build directory.
176:
1.172 lukem 177: 20080503:
178: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
179:
1.171 he 180: 20080521:
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.
187:
1.174 lukem 188: 20080303:
189: Linker warnings are now fatal if $WARNS>0.
190:
1.170 christos 191: 20080126:
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.
196:
1.168 joerg 197: 20071209:
198: The acpiec(4) driver has been split into two attachments. If you
199: get ACPI errors before the attachment, please update your kernel
1.169 wiz 200: configuration file appropriately or see GENERIC for more details.
1.168 joerg 201:
1.166 xtraeme 202: 20071115:
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
1.167 wiz 207: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 208:
1.165 jmmv 209: 20071028:
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
215: for more details.
216:
1.164 gdt 217: 20070913:
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.
226:
1.163 joerg 227: 20070703:
1.199 dholland 228: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
229: calls the target-specific strip program, and the logic to pass
230: down STRIP from make has been removed. This requires a
231: re-installation of tools.
1.163 joerg 232:
1.161 dsl 233: 20070422:
234: The way OS emulations lookup filenames inside the emulation root
235: has been changed. Rather than modify the pathname (and copy back
236: to userspace) namei() and lookup() directly check the emulation
237: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 238: root file system will be relative to that file system - unless they
1.161 dsl 239: start /../ this is useful when the emulated root is a real install
240: that has such links.
241: This might affect symlinks that have been added to reference outside
242: the emulated root.
243:
1.160 jmcneill 244: 20070412:
245: The pckbc driver on sgimips IP32 has been removed. Use macekbc
246: instead. See the GENERIC32_IP3x kernel configuration for an
247: example.
248:
1.159 gdt 249: 20070319:
250: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
251: on many platforms due to incorrect flags settings. If you
252: updated and built after about 20070315, do "nbmake-$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.
257:
1.158 dbj 258: 20070210:
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
263:
1.157 apb 264: 20070209:
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.
274:
1.154 he 275: 20061214:
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/,
1.156 he 281: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
282: as the installation images in distrib/
1.154 he 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.
285:
1.152 christos 286: 20061108:
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.
291:
1.151 rpaulo 292: 20061009:
293: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
294: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
295:
1.150 bjh21 296: 20060814:
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.
301:
1.149 christos 302: 20060703:
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.
306:
1.148 dogcow 307: 20060627:
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'
311: errors will result.
312:
1.1 abs 313: Hints for a more successful build:
314: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 315: Use build.sh, but do not use its "expert mode":
1.132 jmmv 316: This will automatically build the tools in the
1.123 jmc 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.
1.2 mrg 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.
1.1 abs 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.
1.123 jmc 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:
1.1 abs 334: a) cd /usr/src ; make cleandir
1.2 mrg 335: b) Add "OBJMACHINE=yes" to /etc/mk.conf
336: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 337: d) cd /usr/src ; make build
1.2 mrg 338: Note that running "make obj" in a directory will create
339: in obj.$MACHINE directory.
1.1 abs 340: Build to a DESTDIR:
1.123 jmc 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.)
1.1 abs 351: Build often:
352: This keeps critical utilities current enough to not choke
353: on any other part of the source tree that depends on up to
1.123 jmc 354: date functionality. If you use build.sh, you should not have
355: this problem.
1.1 abs 356:
357: What to do if things don't work:
358: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
359: When things don't work there is usually a few things that commonly
360: should be done.
361: 1) make includes
362: This should be done automatically by make build.
363: 2) cd share/mk && make install
364: Again, automatically done by make build.
365:
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...
374: make cleandir
375: rm ...all obj directories...
376: make cleandir # yes, again
377: make obj
378: make depend && make
379:
380: Failsafe rebuild of the entire tree:
381: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
382: If you really want to make sure the source tree is clean and
1.2 mrg 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.
