1.201 ! dsl 1: $NetBSD: UPDATING,v 1.200 2009/07/09 08:04:32 dholland 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:
1.201 ! dsl 19: 20090718:
! 20: libc build changed so that strchr() provides the extra entry
! 21: point for index(). Update build of libc.a (and libc_pic.a)
! 22: may fail because the archive contains the unwanted index.o.
! 23: (Similarly for strrchr() and rindex().)
! 24:
1.198 mrg 25: 20090709:
26: Native Xorg was upgraded again. Builds will probably fail again
27: without a clean objdir, at least for src/external/mit/xorg.
28:
1.197 mrg 29: 20090616:
30: Native Xorg was upgraded. Builds will need a clean objdir for
31: src/external/mit/xorg. Upgrading a system from sets will not
32: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
33: subdirectory has been changed into a file, and this needs to
34: be manually "rm -r"'ed before installing xbase.tgz.
35:
1.195 perry 36: 20090501:
37: Several new functions were added to string.h/libc, and this
38: can cause autoconf problems during the tool build for people
39: who fail to clean out their tools objects properly. If you
40: note messages about stpcpy, stpncpy or strnlen accompanying a
41: failure during the tool build, clean out all your tools
42: objects and start again.
43:
1.194 mrg 44: 20090325:
45: The i386 port was switched to i486 default toolchain. This requires
46: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
47:
1.192 skrll 48: 20090126:
1.193 skrll 49: The __posix_fadvise50 system call changed assembly stub type. You need to
50: 'rm -f __posix_fadvise50.*' in the libc build directory to avoid using
1.192 skrll 51: the old assembly stub.
52:
1.191 joerg 53: 20090202:
54: pkg_install now depends on the pkgdb cache for automatic conflict
55: detection. It is recommented to rebuild the cache with
56: ``pkg_admin rebuild''.
57:
1.184 christos 58: 20090110:
59: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
60: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 61: This is needed even in the MODULAR kernel because there is
62: conditionally compiled code in rtsock.c.
1.184 christos 63: 2. make sure build.sh completes and the binaries in a chroot work
64: before installing.
65: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 66: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 67: are installed properly, and start building libraries first libc
68: and libutil, install them and then continue building all the
69: libraries in src/lib and src/gnu/lib and install them. Once
70: the new libraries are installed, you can restart the build.
71: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 72: rebuild the required packages to update their shared libraries.
73: Any package you rebuild will require rebuilding all the packages
74: that depend on it.
1.186 christos 75: 5. Next time you run pwd_mkdb with the new binary, the file
76: will be upgraded and it will not be backwards compatible.
1.190 apb 77: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
78: lastlogx(5)) have been versioned, and there is a heuristic
79: for utmp. You are better off removing the old files after
80: upgrading. The automated clearing of /var/run during
81: boot, and the automated rotating of files in /var/log by
82: newsyslog(8), may mean that you do not have to remove the
83: files manually.
84: 7. The optional accounting file (/var/account/acct, see
85: accton(8)) has not been versioned, and will need to be
86: removed. The automatic rotation of the accounting file by
87: /etc/daily limits the bad consequences of failure to remove
88: the file.
1.196 dholland 89: 8. Application software that writes time_t to binary files on
90: disk will break or need attention. Most notably: if you are
91: using PostgreSQL < 8.4, you need to dump your databases,
92: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 93:
1.183 pgoyette 94: 20081219:
95: config(1) has been updated, and one of the files it creates -
96: swapnetbsd.o - has changed format. You need to rebuild config
97: (done automatically by build.sh) and then you need to rerun
98: config on all kernel configuration files before rebuilding those
99: kernels.
100:
1.181 cube 101: 20081205:
102: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
103: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
104: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 105:
1.179 tsutsui 106: 20081122:
1.182 tsutsui 107: On i386, various kernel options(4) in GENERIC including
1.180 wiz 108: file systems have been disabled and moved into kernel modules.
109: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 110: following files as well as a new GENERIC kernel:
111:
112: - build and install kernel modules from src/sys/modules
113:
114: - install the latest bootloader, which will load a module
1.180 wiz 115: for the file system from which the kernel is loaded automatically
1.179 tsutsui 116:
1.180 wiz 117: If you have to load your kernel from a file system which is not of
118: the same type as the root file system, you have to load the necessary
119: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 120:
1.178 lukem 121: 20080827:
122: If you built and installed a libc from sources between
123: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
124: which results in false errors reported by lint(1).
125: Since this breaks the libc build itself, manual help is
1.180 wiz 126: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 127: $ (cd lib/libc && make MKLINT=no dependall install)
128:
1.177 christos 129: 20080813:
130: MKDEBUG build was broken because the .depend files did not know
131: about .go files. You need to remove all .depend files and rebuild.
132:
1.200 dholland 133: 20080802:
134: A regression in binary compatibility for pthread_mutex_t has
135: been fixed. Unfortunately, the price is breaking compatibility
136: for -current.
137:
138: Threaded programs (using libpthread) and C++ programs (using
139: libstdc++) compiled after 20070907 and before 20080802 need to
140: be recompiled.
141:
142: One way to find affected pkgsrc packages:
143:
144: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
145: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
146:
1.175 simonb 147: 20080731:
148: WAPBL (metadata journaling support) has been added, but at this
149: time isn't backwards compatible with pre-WAPBL aware kernels
150: and userland (fsck_ffs in particular). Please make sure you
151: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 152: especially an uncleanly mounted journaled filesystem. WAPBL
153: also requires the super block to be in the UFS2 format. You
154: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 155:
1.174 lukem 156: 20080721:
157: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
158: isn't defined.
159:
1.173 freza 160: 20080531:
161: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
162: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
163: utility needs to be rebuilt and reinstalled as older binaries
164: won't work correctly. The following sequence of commands:
165:
166: $ (cd sys/sys/ && nbmake-$arch includes)
167: $ (cd sbin/drvctl/ && nbmake-$arch clean)
168: $ (cd sbin/drvctl/ && nbmake-$arch all)
169:
170: leaves new drvctl utility in sbin/drvctl build directory.
171:
1.172 lukem 172: 20080503:
173: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
174:
1.171 he 175: 20080521:
176: For a while, unprivileged UPDATE builds would fail to
177: succeed at the checkflist stage, complaining that
178: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
179: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
180: If you already hit this problem, update the .mk file,
181: remove ${DESTDIR}/stand/<arch>, and re-run the build.
182:
1.174 lukem 183: 20080303:
184: Linker warnings are now fatal if $WARNS>0.
185:
1.170 christos 186: 20080126:
187: The posix_fadvise system call has been changed from an assembly
188: stub, to a c file that calls an assembly stub. You need to
189: 'rm -f posix_fadvise.* .depend' in the libc build directory to
190: avoid using the old assembly stub.
191:
1.168 joerg 192: 20071209:
193: The acpiec(4) driver has been split into two attachments. If you
194: get ACPI errors before the attachment, please update your kernel
1.169 wiz 195: configuration file appropriately or see GENERIC for more details.
1.168 joerg 196:
1.166 xtraeme 197: 20071115:
198: The it(4) driver has been renamed to itesio(4) and the old port
199: argument specified in the kernel configuration file is not valid
200: anymore. The itesio(4) driver now uses the Super I/O address port
201: rather than the EC address port. Please update your kernel
1.167 wiz 202: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 203:
1.165 jmmv 204: 20071028:
205: The pccons(4) driver has been removed from the NetBSD/shark port.
206: You need to update any custom kernel configuration file you have
207: to remove any references to pccons (which includes removing the
208: now useless XSERVER option) and replace them with the correct
209: entries for the wscons driver. See the GENERIC configuration file
210: for more details.
211:
1.164 gdt 212: 20070913:
213: A latent bug in dhclient/dhcpd that caused it to be unable to
214: enumerate interfaces was fixed. The bug began to cause
215: problems after 20070911 when the kernel's SIOCGIFCONF
216: implementation was repaired. From 20070529 to 20070911 racoon
217: could not enumerate interfaces. (These are noted because
218: normal kernel/userspace version matching hygiene is not
219: sufficient to avoid this problem.) Ensure that both kernel
220: and userland are from after 20070913.
221:
1.163 joerg 222: 20070703:
1.199 dholland 223: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
224: calls the target-specific strip program, and the logic to pass
225: down STRIP from make has been removed. This requires a
226: re-installation of tools.
1.163 joerg 227:
1.161 dsl 228: 20070422:
229: The way OS emulations lookup filenames inside the emulation root
230: has been changed. Rather than modify the pathname (and copy back
231: to userspace) namei() and lookup() directly check the emulation
232: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 233: root file system will be relative to that file system - unless they
1.161 dsl 234: start /../ this is useful when the emulated root is a real install
235: that has such links.
236: This might affect symlinks that have been added to reference outside
237: the emulated root.
238:
1.160 jmcneill 239: 20070412:
240: The pckbc driver on sgimips IP32 has been removed. Use macekbc
241: instead. See the GENERIC32_IP3x kernel configuration for an
242: example.
243:
1.159 gdt 244: 20070319:
245: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
246: on many platforms due to incorrect flags settings. If you
247: updated and built after about 20070315, do "nbmake-$arch
248: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
249: rebuild of object files that might have been built
250: incorrectly, and ensure that you have at least
251: src/lib/libc/Makefile 1.130.
252:
1.158 dbj 253: 20070210:
254: src/sys/sys/{sa.h,savar.h} were removed.
255: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
256: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
257: will allow dependencies on those files to get get rebuilt
258:
1.157 apb 259: 20070209:
260: The threading model was changed when the newlock2 branch
261: was merged to NetBSD-current. If you boot with a new
262: kernel (version 4.99.10), then you also need a new pthread
263: library (/usr/lib/libpthread.so.0.7). If you boot with
264: an old kernel, then you need the old pthread library
265: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
266: the pthread library in sync, old threaded applications should
267: continue to work with an old or new kernel. Note that named(8)
268: is the only threaded application in the base system.
269:
1.154 he 270: 20061214:
271: Following the move of string_to_flags() and flags_to_string()
272: from the bin/ls/ sources to libutil, users doing UPDATE builds
273: will need to do a "make cleandir" in
274: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
275: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 276: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
277: as the installation images in distrib/
1.154 he 278: in order to excise stale references to the old stat_flags.h header
279: file in the ls sources -- stat_flags.h has been removed.
280:
1.152 christos 281: 20061108:
282: The configure script used in the src/tools/gcc compiler has been
283: changed to indicate that our libc has ssp support built-in and
284: does not depend on -lssp and -lssp-nonshared. You'll need to
285: make clean in src/tools/gcc first to rebuild the compiler.
286:
1.151 rpaulo 287: 20061009:
288: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
289: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
290:
1.150 bjh21 291: 20060814:
292: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
293: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
294: kernel configuration for an example. X servers from the last
295: few years should cope.
296:
1.149 christos 297: 20060703:
298: MPACPI is no more. We always configure PCI interrupts using ACPI
299: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
300: to ACPI_SCANPCI. Thanks to work from fvdl.
301:
1.148 dogcow 302: 20060627:
303: socket(2) has changed, and its system call has been versioned.
304: For userlands with the old version of socket(2), make sure that
305: your kernel has 'options COMPAT_30' set, or else 'bad system call'
306: errors will result.
307:
1.1 abs 308: Hints for a more successful build:
309: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 310: Use build.sh, but do not use its "expert mode":
1.132 jmmv 311: This will automatically build the tools in the
1.123 jmc 312: correct order, and it will keep the tools and the
313: new build products from interfering with the running
314: system. This will allow you to ignore most of the
315: other advice in this file.
1.2 mrg 316: Build a new kernel first:
317: This makes sure that any new system calls or features
318: expected by the new userland will be present. This
319: helps to avoid critical errors when upgrading.
1.1 abs 320: Use object directories:
321: This helps to keep stale object
322: files from polluting the build if a Makefile "forgets"
323: about one. It also makes it easier to clean up after
324: a build. It's also necessary if you want to use the
325: same source tree for multiple machines.
1.123 jmc 326: To use object directories with build.sh:
327: a) invoke build.sh with the "-M" or "-O" options.
328: To use object directories without using build.sh:
1.1 abs 329: a) cd /usr/src ; make cleandir
1.2 mrg 330: b) Add "OBJMACHINE=yes" to /etc/mk.conf
331: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 332: d) cd /usr/src ; make build
1.2 mrg 333: Note that running "make obj" in a directory will create
334: in obj.$MACHINE directory.
1.1 abs 335: Build to a DESTDIR:
1.123 jmc 336: This helps to keep old installed files (especially libraries)
337: from interfering with the new build.
338: To build to a DESTDIR with build.sh, use the "-D" option.
339: To build to a DESTDIR without using build.sh, set the DESTDIR
340: environment variable before running make build. It should be
341: set to the pathname of an initially empty directory.
342: Problems: if you do not use build.sh, you might need to
343: update critical utilities without using DESTDIR since
344: nothing is executed from what is installed in DESTDIR.
345: (See critical utils, below.)
1.1 abs 346: Build often:
347: This keeps critical utilities current enough to not choke
348: on any other part of the source tree that depends on up to
1.123 jmc 349: date functionality. If you use build.sh, you should not have
350: this problem.
1.1 abs 351:
352: What to do if things don't work:
353: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
354: When things don't work there is usually a few things that commonly
355: should be done.
356: 1) make includes
357: This should be done automatically by make build.
358: 2) cd share/mk && make install
359: Again, automatically done by make build.
360:
361: Failsafe rebuild of a small part of the tree:
362: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
363: To make sure you rebuild something correctly you want to do
364: something like the following:
365: 1) Make sure the includes and .mk files are up to date.
366: 2) Make sure any program used to build the particular
367: utility is up to date. (yacc, lex, etc...)
368: 3) cd ...path/to/util...
369: make cleandir
370: rm ...all obj directories...
371: make cleandir # yes, again
372: make obj
373: make depend && make
374:
375: Failsafe rebuild of the entire tree:
376: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
377: If you really want to make sure the source tree is clean and
1.2 mrg 378: ready for a build try the following. Note that sourcing /etc/mk.conf
379: (a make(1) Makefile) in this manner is not right, and will not work
380: for anyone who uses any make(1) features in /etc/mk.conf.
