1.209 ! njoly 1: $NetBSD: UPDATING,v 1.208 2010/02/04 22:25:21 roy 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.

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