1.203 ! dyoung 1: $NetBSD: UPDATING,v 1.202 2009/10/02 03:13:23 mrg 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: ^^^^^^^^^^^^^^^
1.138 lukem 18:
1.203 ! dyoung 19: 20091101:
! 20: After updating, it may be make the 'cleandir' target in
! 21: src/tools/yacc/ and in src/usr.bin/yacc/ before a 'build.sh
! 22: -u tools' or 'build.sh -u distribution'.
! 23:
1.202 mrg 24: 20091001:
25: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
26: symlink, failing the build. Delete the link, and the subdir
27: it is in, and retry your build.
28:
1.201 dsl 29: 20090718:
30: libc build changed so that strchr() provides the extra entry
31: point for index(). Update build of libc.a (and libc_pic.a)
32: may fail because the archive contains the unwanted index.o.
33: (Similarly for strrchr() and rindex().)
34:
1.198 mrg 35: 20090709:
36: Native Xorg was upgraded again. Builds will probably fail again
37: without a clean objdir, at least for src/external/mit/xorg.
38:
1.197 mrg 39: 20090616:
40: Native Xorg was upgraded. Builds will need a clean objdir for
41: src/external/mit/xorg. Upgrading a system from sets will not
42: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
43: subdirectory has been changed into a file, and this needs to
44: be manually "rm -r"'ed before installing xbase.tgz.
45:
1.195 perry 46: 20090501:
47: Several new functions were added to string.h/libc, and this
48: can cause autoconf problems during the tool build for people
49: who fail to clean out their tools objects properly. If you
50: note messages about stpcpy, stpncpy or strnlen accompanying a
51: failure during the tool build, clean out all your tools
52: objects and start again.
53:
1.194 mrg 54: 20090325:
55: The i386 port was switched to i486 default toolchain. This requires
56: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
57:
1.192 skrll 58: 20090126:
1.193 skrll 59: The __posix_fadvise50 system call changed assembly stub type. You need to
60: 'rm -f __posix_fadvise50.*' in the libc build directory to avoid using
1.192 skrll 61: the old assembly stub.
62:
1.191 joerg 63: 20090202:
64: pkg_install now depends on the pkgdb cache for automatic conflict
65: detection. It is recommented to rebuild the cache with
66: ``pkg_admin rebuild''.
67:
1.184 christos 68: 20090110:
69: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
70: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 71: This is needed even in the MODULAR kernel because there is
72: conditionally compiled code in rtsock.c.
1.184 christos 73: 2. make sure build.sh completes and the binaries in a chroot work
74: before installing.
75: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 76: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 77: are installed properly, and start building libraries first libc
78: and libutil, install them and then continue building all the
79: libraries in src/lib and src/gnu/lib and install them. Once
80: the new libraries are installed, you can restart the build.
81: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 82: rebuild the required packages to update their shared libraries.
83: Any package you rebuild will require rebuilding all the packages
84: that depend on it.
1.186 christos 85: 5. Next time you run pwd_mkdb with the new binary, the file
86: will be upgraded and it will not be backwards compatible.
1.190 apb 87: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
88: lastlogx(5)) have been versioned, and there is a heuristic
89: for utmp. You are better off removing the old files after
90: upgrading. The automated clearing of /var/run during
91: boot, and the automated rotating of files in /var/log by
92: newsyslog(8), may mean that you do not have to remove the
93: files manually.
94: 7. The optional accounting file (/var/account/acct, see
95: accton(8)) has not been versioned, and will need to be
96: removed. The automatic rotation of the accounting file by
97: /etc/daily limits the bad consequences of failure to remove
98: the file.
1.196 dholland 99: 8. Application software that writes time_t to binary files on
100: disk will break or need attention. Most notably: if you are
101: using PostgreSQL < 8.4, you need to dump your databases,
102: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 103:
1.183 pgoyette 104: 20081219:
105: config(1) has been updated, and one of the files it creates -
106: swapnetbsd.o - has changed format. You need to rebuild config
107: (done automatically by build.sh) and then you need to rerun
108: config on all kernel configuration files before rebuilding those
109: kernels.
110:
1.181 cube 111: 20081205:
112: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
113: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
114: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 115:
1.179 tsutsui 116: 20081122:
1.182 tsutsui 117: On i386, various kernel options(4) in GENERIC including
1.180 wiz 118: file systems have been disabled and moved into kernel modules.
119: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 120: following files as well as a new GENERIC kernel:
121:
122: - build and install kernel modules from src/sys/modules
123:
124: - install the latest bootloader, which will load a module
1.180 wiz 125: for the file system from which the kernel is loaded automatically
1.179 tsutsui 126:
1.180 wiz 127: If you have to load your kernel from a file system which is not of
128: the same type as the root file system, you have to load the necessary
129: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 130:
1.178 lukem 131: 20080827:
132: If you built and installed a libc from sources between
133: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
134: which results in false errors reported by lint(1).
135: Since this breaks the libc build itself, manual help is
1.180 wiz 136: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 137: $ (cd lib/libc && make MKLINT=no dependall install)
138:
1.177 christos 139: 20080813:
140: MKDEBUG build was broken because the .depend files did not know
141: about .go files. You need to remove all .depend files and rebuild.
142:
1.200 dholland 143: 20080802:
144: A regression in binary compatibility for pthread_mutex_t has
145: been fixed. Unfortunately, the price is breaking compatibility
146: for -current.
147:
148: Threaded programs (using libpthread) and C++ programs (using
149: libstdc++) compiled after 20070907 and before 20080802 need to
150: be recompiled.
151:
152: One way to find affected pkgsrc packages:
153:
154: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
155: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
156:
1.175 simonb 157: 20080731:
158: WAPBL (metadata journaling support) has been added, but at this
159: time isn't backwards compatible with pre-WAPBL aware kernels
160: and userland (fsck_ffs in particular). Please make sure you
161: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 162: especially an uncleanly mounted journaled filesystem. WAPBL
163: also requires the super block to be in the UFS2 format. You
164: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 165:
1.174 lukem 166: 20080721:
167: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
168: isn't defined.
169:
1.173 freza 170: 20080531:
171: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
172: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
173: utility needs to be rebuilt and reinstalled as older binaries
174: won't work correctly. The following sequence of commands:
175:
176: $ (cd sys/sys/ && nbmake-$arch includes)
177: $ (cd sbin/drvctl/ && nbmake-$arch clean)
178: $ (cd sbin/drvctl/ && nbmake-$arch all)
179:
180: leaves new drvctl utility in sbin/drvctl build directory.
181:
1.172 lukem 182: 20080503:
183: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
184:
1.171 he 185: 20080521:
186: For a while, unprivileged UPDATE builds would fail to
187: succeed at the checkflist stage, complaining that
188: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
189: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
190: If you already hit this problem, update the .mk file,
191: remove ${DESTDIR}/stand/<arch>, and re-run the build.
192:
1.174 lukem 193: 20080303:
194: Linker warnings are now fatal if $WARNS>0.
195:
1.170 christos 196: 20080126:
197: The posix_fadvise system call has been changed from an assembly
198: stub, to a c file that calls an assembly stub. You need to
199: 'rm -f posix_fadvise.* .depend' in the libc build directory to
200: avoid using the old assembly stub.
201:
1.168 joerg 202: 20071209:
203: The acpiec(4) driver has been split into two attachments. If you
204: get ACPI errors before the attachment, please update your kernel
1.169 wiz 205: configuration file appropriately or see GENERIC for more details.
1.168 joerg 206:
1.166 xtraeme 207: 20071115:
208: The it(4) driver has been renamed to itesio(4) and the old port
209: argument specified in the kernel configuration file is not valid
210: anymore. The itesio(4) driver now uses the Super I/O address port
211: rather than the EC address port. Please update your kernel
1.167 wiz 212: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 213:
1.165 jmmv 214: 20071028:
215: The pccons(4) driver has been removed from the NetBSD/shark port.
216: You need to update any custom kernel configuration file you have
217: to remove any references to pccons (which includes removing the
218: now useless XSERVER option) and replace them with the correct
219: entries for the wscons driver. See the GENERIC configuration file
220: for more details.
221:
1.164 gdt 222: 20070913:
223: A latent bug in dhclient/dhcpd that caused it to be unable to
224: enumerate interfaces was fixed. The bug began to cause
225: problems after 20070911 when the kernel's SIOCGIFCONF
226: implementation was repaired. From 20070529 to 20070911 racoon
227: could not enumerate interfaces. (These are noted because
228: normal kernel/userspace version matching hygiene is not
229: sufficient to avoid this problem.) Ensure that both kernel
230: and userland are from after 20070913.
231:
1.163 joerg 232: 20070703:
1.199 dholland 233: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
234: calls the target-specific strip program, and the logic to pass
235: down STRIP from make has been removed. This requires a
236: re-installation of tools.
1.163 joerg 237:
1.161 dsl 238: 20070422:
239: The way OS emulations lookup filenames inside the emulation root
240: has been changed. Rather than modify the pathname (and copy back
241: to userspace) namei() and lookup() directly check the emulation
242: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 243: root file system will be relative to that file system - unless they
1.161 dsl 244: start /../ this is useful when the emulated root is a real install
245: that has such links.
246: This might affect symlinks that have been added to reference outside
247: the emulated root.
248:
1.160 jmcneill 249: 20070412:
250: The pckbc driver on sgimips IP32 has been removed. Use macekbc
251: instead. See the GENERIC32_IP3x kernel configuration for an
252: example.
253:
1.159 gdt 254: 20070319:
255: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
256: on many platforms due to incorrect flags settings. If you
257: updated and built after about 20070315, do "nbmake-$arch
258: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
259: rebuild of object files that might have been built
260: incorrectly, and ensure that you have at least
261: src/lib/libc/Makefile 1.130.
262:
1.158 dbj 263: 20070210:
264: src/sys/sys/{sa.h,savar.h} were removed.
265: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
266: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
267: will allow dependencies on those files to get get rebuilt
268:
1.157 apb 269: 20070209:
270: The threading model was changed when the newlock2 branch
271: was merged to NetBSD-current. If you boot with a new
272: kernel (version 4.99.10), then you also need a new pthread
273: library (/usr/lib/libpthread.so.0.7). If you boot with
274: an old kernel, then you need the old pthread library
275: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
276: the pthread library in sync, old threaded applications should
277: continue to work with an old or new kernel. Note that named(8)
278: is the only threaded application in the base system.
279:
1.154 he 280: 20061214:
281: Following the move of string_to_flags() and flags_to_string()
282: from the bin/ls/ sources to libutil, users doing UPDATE builds
283: will need to do a "make cleandir" in
284: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
285: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 286: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
287: as the installation images in distrib/
1.154 he 288: in order to excise stale references to the old stat_flags.h header
289: file in the ls sources -- stat_flags.h has been removed.
290:
1.152 christos 291: 20061108:
292: The configure script used in the src/tools/gcc compiler has been
293: changed to indicate that our libc has ssp support built-in and
294: does not depend on -lssp and -lssp-nonshared. You'll need to
295: make clean in src/tools/gcc first to rebuild the compiler.
296:
1.151 rpaulo 297: 20061009:
298: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
299: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
300:
1.150 bjh21 301: 20060814:
302: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
303: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
304: kernel configuration for an example. X servers from the last
305: few years should cope.
306:
1.149 christos 307: 20060703:
308: MPACPI is no more. We always configure PCI interrupts using ACPI
309: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
310: to ACPI_SCANPCI. Thanks to work from fvdl.
311:
1.148 dogcow 312: 20060627:
313: socket(2) has changed, and its system call has been versioned.
314: For userlands with the old version of socket(2), make sure that
315: your kernel has 'options COMPAT_30' set, or else 'bad system call'
316: errors will result.
317:
1.1 abs 318: Hints for a more successful build:
319: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 320: Use build.sh, but do not use its "expert mode":
1.132 jmmv 321: This will automatically build the tools in the
1.123 jmc 322: correct order, and it will keep the tools and the
323: new build products from interfering with the running
324: system. This will allow you to ignore most of the
325: other advice in this file.
1.2 mrg 326: Build a new kernel first:
327: This makes sure that any new system calls or features
328: expected by the new userland will be present. This
329: helps to avoid critical errors when upgrading.
1.1 abs 330: Use object directories:
331: This helps to keep stale object
332: files from polluting the build if a Makefile "forgets"
333: about one. It also makes it easier to clean up after
334: a build. It's also necessary if you want to use the
335: same source tree for multiple machines.
1.123 jmc 336: To use object directories with build.sh:
337: a) invoke build.sh with the "-M" or "-O" options.
338: To use object directories without using build.sh:
1.1 abs 339: a) cd /usr/src ; make cleandir
1.2 mrg 340: b) Add "OBJMACHINE=yes" to /etc/mk.conf
341: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 342: d) cd /usr/src ; make build
1.2 mrg 343: Note that running "make obj" in a directory will create
344: in obj.$MACHINE directory.
1.1 abs 345: Build to a DESTDIR:
1.123 jmc 346: This helps to keep old installed files (especially libraries)
347: from interfering with the new build.
348: To build to a DESTDIR with build.sh, use the "-D" option.
349: To build to a DESTDIR without using build.sh, set the DESTDIR
350: environment variable before running make build. It should be
351: set to the pathname of an initially empty directory.
352: Problems: if you do not use build.sh, you might need to
353: update critical utilities without using DESTDIR since
354: nothing is executed from what is installed in DESTDIR.
355: (See critical utils, below.)
1.1 abs 356: Build often:
357: This keeps critical utilities current enough to not choke
358: on any other part of the source tree that depends on up to
1.123 jmc 359: date functionality. If you use build.sh, you should not have
360: this problem.
1.1 abs 361:
362: What to do if things don't work:
363: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
364: When things don't work there is usually a few things that commonly
365: should be done.
366: 1) make includes
367: This should be done automatically by make build.
368: 2) cd share/mk && make install
369: Again, automatically done by make build.
370:
371: Failsafe rebuild of a small part of the tree:
372: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
373: To make sure you rebuild something correctly you want to do
374: something like the following:
375: 1) Make sure the includes and .mk files are up to date.
376: 2) Make sure any program used to build the particular
377: utility is up to date. (yacc, lex, etc...)
378: 3) cd ...path/to/util...
379: make cleandir
380: rm ...all obj directories...
381: make cleandir # yes, again
382: make obj
383: make depend && make
384:
385: Failsafe rebuild of the entire tree:
386: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
387: If you really want to make sure the source tree is clean and
1.2 mrg 388: ready for a build try the following. Note that sourcing /etc/mk.conf
389: (a make(1) Makefile) in this manner is not right, and will not work
390: for anyone who uses any make(1) features in /etc/mk.conf.
