1.208 ! roy 1: $NetBSD: UPDATING,v 1.207 2009/12/26 11:00:46 mbalmer 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:
1.208 ! roy 19: 20100204:
! 20: The termcap database has been removed from the sources,
! 21: but has not been marked obsolete so it is not removed
! 22: from the system when upgrading.
! 23: As such, you will need to remove them from your object
! 24: and destination directories.
! 25:
1.203 dyoung 26: 20091101:
1.205 dholland 27: After updating, it may be necessary to make the 'cleandir'
28: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
29: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
30: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 31:
1.202 mrg 32: 20091001:
1.206 dholland 33: On amd64 you must rebuild tools (to get the new binutils)
34: before building a kernel, or the build fails on cpufunc.S.
35:
36: 20091001:
1.202 mrg 37: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
38: symlink, failing the build. Delete the link, and the subdir
39: it is in, and retry your build.
40:
1.201 dsl 41: 20090718:
42: libc build changed so that strchr() provides the extra entry
43: point for index(). Update build of libc.a (and libc_pic.a)
44: may fail because the archive contains the unwanted index.o.
45: (Similarly for strrchr() and rindex().)
46:
1.198 mrg 47: 20090709:
48: Native Xorg was upgraded again. Builds will probably fail again
49: without a clean objdir, at least for src/external/mit/xorg.
50:
1.197 mrg 51: 20090616:
52: Native Xorg was upgraded. Builds will need a clean objdir for
53: src/external/mit/xorg. Upgrading a system from sets will not
54: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
55: subdirectory has been changed into a file, and this needs to
56: be manually "rm -r"'ed before installing xbase.tgz.
57:
1.195 perry 58: 20090501:
59: Several new functions were added to string.h/libc, and this
60: can cause autoconf problems during the tool build for people
61: who fail to clean out their tools objects properly. If you
62: note messages about stpcpy, stpncpy or strnlen accompanying a
63: failure during the tool build, clean out all your tools
64: objects and start again.
65:
1.194 mrg 66: 20090325:
67: The i386 port was switched to i486 default toolchain. This requires
68: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
69:
1.192 skrll 70: 20090126:
1.207 mbalmer 71: The __posix_fadvise50 system call changed assembly stub type. You
72: need to 'rm -f __posix_fadvise50.*' in the libc build directory
73: to avoid using the old assembly stub.
1.192 skrll 74:
1.191 joerg 75: 20090202:
76: pkg_install now depends on the pkgdb cache for automatic conflict
77: detection. It is recommented to rebuild the cache with
78: ``pkg_admin rebuild''.
79:
1.184 christos 80: 20090110:
81: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
82: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 83: This is needed even in the MODULAR kernel because there is
84: conditionally compiled code in rtsock.c.
1.184 christos 85: 2. make sure build.sh completes and the binaries in a chroot work
86: before installing.
87: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 88: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 89: are installed properly, and start building libraries first libc
90: and libutil, install them and then continue building all the
91: libraries in src/lib and src/gnu/lib and install them. Once
92: the new libraries are installed, you can restart the build.
93: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 94: rebuild the required packages to update their shared libraries.
95: Any package you rebuild will require rebuilding all the packages
96: that depend on it.
1.186 christos 97: 5. Next time you run pwd_mkdb with the new binary, the file
98: will be upgraded and it will not be backwards compatible.
1.190 apb 99: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
100: lastlogx(5)) have been versioned, and there is a heuristic
101: for utmp. You are better off removing the old files after
102: upgrading. The automated clearing of /var/run during
103: boot, and the automated rotating of files in /var/log by
104: newsyslog(8), may mean that you do not have to remove the
105: files manually.
106: 7. The optional accounting file (/var/account/acct, see
107: accton(8)) has not been versioned, and will need to be
108: removed. The automatic rotation of the accounting file by
109: /etc/daily limits the bad consequences of failure to remove
110: the file.
1.196 dholland 111: 8. Application software that writes time_t to binary files on
112: disk will break or need attention. Most notably: if you are
113: using PostgreSQL < 8.4, you need to dump your databases,
114: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 115:
1.183 pgoyette 116: 20081219:
117: config(1) has been updated, and one of the files it creates -
118: swapnetbsd.o - has changed format. You need to rebuild config
119: (done automatically by build.sh) and then you need to rerun
120: config on all kernel configuration files before rebuilding those
121: kernels.
122:
1.181 cube 123: 20081205:
124: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
125: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
126: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 127:
1.179 tsutsui 128: 20081122:
1.182 tsutsui 129: On i386, various kernel options(4) in GENERIC including
1.180 wiz 130: file systems have been disabled and moved into kernel modules.
131: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 132: following files as well as a new GENERIC kernel:
133:
134: - build and install kernel modules from src/sys/modules
135:
136: - install the latest bootloader, which will load a module
1.180 wiz 137: for the file system from which the kernel is loaded automatically
1.179 tsutsui 138:
1.180 wiz 139: If you have to load your kernel from a file system which is not of
140: the same type as the root file system, you have to load the necessary
141: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 142:
1.178 lukem 143: 20080827:
144: If you built and installed a libc from sources between
145: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
146: which results in false errors reported by lint(1).
147: Since this breaks the libc build itself, manual help is
1.180 wiz 148: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 149: $ (cd lib/libc && make MKLINT=no dependall install)
150:
1.177 christos 151: 20080813:
152: MKDEBUG build was broken because the .depend files did not know
153: about .go files. You need to remove all .depend files and rebuild.
154:
1.200 dholland 155: 20080802:
156: A regression in binary compatibility for pthread_mutex_t has
157: been fixed. Unfortunately, the price is breaking compatibility
158: for -current.
159:
160: Threaded programs (using libpthread) and C++ programs (using
161: libstdc++) compiled after 20070907 and before 20080802 need to
162: be recompiled.
163:
164: One way to find affected pkgsrc packages:
165:
166: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
167: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
168:
1.175 simonb 169: 20080731:
170: WAPBL (metadata journaling support) has been added, but at this
171: time isn't backwards compatible with pre-WAPBL aware kernels
172: and userland (fsck_ffs in particular). Please make sure you
173: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 174: especially an uncleanly mounted journaled filesystem. WAPBL
175: also requires the super block to be in the UFS2 format. You
176: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 177:
1.174 lukem 178: 20080721:
179: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
180: isn't defined.
181:
1.173 freza 182: 20080531:
183: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
184: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
185: utility needs to be rebuilt and reinstalled as older binaries
186: won't work correctly. The following sequence of commands:
187:
188: $ (cd sys/sys/ && nbmake-$arch includes)
189: $ (cd sbin/drvctl/ && nbmake-$arch clean)
190: $ (cd sbin/drvctl/ && nbmake-$arch all)
191:
192: leaves new drvctl utility in sbin/drvctl build directory.
193:
1.172 lukem 194: 20080503:
195: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
196:
1.171 he 197: 20080521:
198: For a while, unprivileged UPDATE builds would fail to
199: succeed at the checkflist stage, complaining that
200: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
201: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
202: If you already hit this problem, update the .mk file,
203: remove ${DESTDIR}/stand/<arch>, and re-run the build.
204:
1.174 lukem 205: 20080303:
206: Linker warnings are now fatal if $WARNS>0.
207:
1.170 christos 208: 20080126:
209: The posix_fadvise system call has been changed from an assembly
210: stub, to a c file that calls an assembly stub. You need to
211: 'rm -f posix_fadvise.* .depend' in the libc build directory to
212: avoid using the old assembly stub.
213:
1.168 joerg 214: 20071209:
215: The acpiec(4) driver has been split into two attachments. If you
216: get ACPI errors before the attachment, please update your kernel
1.169 wiz 217: configuration file appropriately or see GENERIC for more details.
1.168 joerg 218:
1.166 xtraeme 219: 20071115:
220: The it(4) driver has been renamed to itesio(4) and the old port
221: argument specified in the kernel configuration file is not valid
222: anymore. The itesio(4) driver now uses the Super I/O address port
223: rather than the EC address port. Please update your kernel
1.167 wiz 224: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 225:
1.165 jmmv 226: 20071028:
227: The pccons(4) driver has been removed from the NetBSD/shark port.
228: You need to update any custom kernel configuration file you have
229: to remove any references to pccons (which includes removing the
230: now useless XSERVER option) and replace them with the correct
231: entries for the wscons driver. See the GENERIC configuration file
232: for more details.
233:
1.164 gdt 234: 20070913:
235: A latent bug in dhclient/dhcpd that caused it to be unable to
236: enumerate interfaces was fixed. The bug began to cause
237: problems after 20070911 when the kernel's SIOCGIFCONF
238: implementation was repaired. From 20070529 to 20070911 racoon
239: could not enumerate interfaces. (These are noted because
240: normal kernel/userspace version matching hygiene is not
241: sufficient to avoid this problem.) Ensure that both kernel
242: and userland are from after 20070913.
243:
1.163 joerg 244: 20070703:
1.199 dholland 245: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
246: calls the target-specific strip program, and the logic to pass
247: down STRIP from make has been removed. This requires a
248: re-installation of tools.
1.163 joerg 249:
1.161 dsl 250: 20070422:
251: The way OS emulations lookup filenames inside the emulation root
252: has been changed. Rather than modify the pathname (and copy back
253: to userspace) namei() and lookup() directly check the emulation
254: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 255: root file system will be relative to that file system - unless they
1.161 dsl 256: start /../ this is useful when the emulated root is a real install
257: that has such links.
258: This might affect symlinks that have been added to reference outside
259: the emulated root.
260:
1.160 jmcneill 261: 20070412:
262: The pckbc driver on sgimips IP32 has been removed. Use macekbc
263: instead. See the GENERIC32_IP3x kernel configuration for an
264: example.
265:
1.159 gdt 266: 20070319:
267: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
268: on many platforms due to incorrect flags settings. If you
269: updated and built after about 20070315, do "nbmake-$arch
270: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
271: rebuild of object files that might have been built
272: incorrectly, and ensure that you have at least
273: src/lib/libc/Makefile 1.130.
274:
1.158 dbj 275: 20070210:
276: src/sys/sys/{sa.h,savar.h} were removed.
277: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
278: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
279: will allow dependencies on those files to get get rebuilt
280:
1.157 apb 281: 20070209:
282: The threading model was changed when the newlock2 branch
283: was merged to NetBSD-current. If you boot with a new
284: kernel (version 4.99.10), then you also need a new pthread
285: library (/usr/lib/libpthread.so.0.7). If you boot with
286: an old kernel, then you need the old pthread library
287: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
288: the pthread library in sync, old threaded applications should
289: continue to work with an old or new kernel. Note that named(8)
290: is the only threaded application in the base system.
291:
1.154 he 292: 20061214:
293: Following the move of string_to_flags() and flags_to_string()
294: from the bin/ls/ sources to libutil, users doing UPDATE builds
295: will need to do a "make cleandir" in
296: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
297: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 298: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
299: as the installation images in distrib/
1.154 he 300: in order to excise stale references to the old stat_flags.h header
301: file in the ls sources -- stat_flags.h has been removed.
302:
1.152 christos 303: 20061108:
304: The configure script used in the src/tools/gcc compiler has been
305: changed to indicate that our libc has ssp support built-in and
306: does not depend on -lssp and -lssp-nonshared. You'll need to
307: make clean in src/tools/gcc first to rebuild the compiler.
308:
1.151 rpaulo 309: 20061009:
310: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
311: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
312:
1.150 bjh21 313: 20060814:
314: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
315: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
316: kernel configuration for an example. X servers from the last
317: few years should cope.
318:
1.149 christos 319: 20060703:
320: MPACPI is no more. We always configure PCI interrupts using ACPI
321: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
322: to ACPI_SCANPCI. Thanks to work from fvdl.
323:
1.148 dogcow 324: 20060627:
325: socket(2) has changed, and its system call has been versioned.
326: For userlands with the old version of socket(2), make sure that
327: your kernel has 'options COMPAT_30' set, or else 'bad system call'
328: errors will result.
329:
1.1 abs 330: Hints for a more successful build:
331: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 332: Use build.sh, but do not use its "expert mode":
1.132 jmmv 333: This will automatically build the tools in the
1.123 jmc 334: correct order, and it will keep the tools and the
335: new build products from interfering with the running
336: system. This will allow you to ignore most of the
337: other advice in this file.
1.2 mrg 338: Build a new kernel first:
339: This makes sure that any new system calls or features
340: expected by the new userland will be present. This
341: helps to avoid critical errors when upgrading.
1.1 abs 342: Use object directories:
343: This helps to keep stale object
344: files from polluting the build if a Makefile "forgets"
345: about one. It also makes it easier to clean up after
346: a build. It's also necessary if you want to use the
347: same source tree for multiple machines.
1.123 jmc 348: To use object directories with build.sh:
349: a) invoke build.sh with the "-M" or "-O" options.
350: To use object directories without using build.sh:
1.1 abs 351: a) cd /usr/src ; make cleandir
1.2 mrg 352: b) Add "OBJMACHINE=yes" to /etc/mk.conf
353: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 354: d) cd /usr/src ; make build
1.2 mrg 355: Note that running "make obj" in a directory will create
356: in obj.$MACHINE directory.
1.1 abs 357: Build to a DESTDIR:
1.123 jmc 358: This helps to keep old installed files (especially libraries)
359: from interfering with the new build.
360: To build to a DESTDIR with build.sh, use the "-D" option.
361: To build to a DESTDIR without using build.sh, set the DESTDIR
362: environment variable before running make build. It should be
363: set to the pathname of an initially empty directory.
364: Problems: if you do not use build.sh, you might need to
365: update critical utilities without using DESTDIR since
366: nothing is executed from what is installed in DESTDIR.
367: (See critical utils, below.)
1.1 abs 368: Build often:
369: This keeps critical utilities current enough to not choke
370: on any other part of the source tree that depends on up to
1.123 jmc 371: date functionality. If you use build.sh, you should not have
372: this problem.
1.1 abs 373:
374: What to do if things don't work:
375: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
376: When things don't work there is usually a few things that commonly
377: should be done.
378: 1) make includes
379: This should be done automatically by make build.
380: 2) cd share/mk && make install
381: Again, automatically done by make build.
382:
383: Failsafe rebuild of a small part of the tree:
384: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
385: To make sure you rebuild something correctly you want to do
386: something like the following:
387: 1) Make sure the includes and .mk files are up to date.
388: 2) Make sure any program used to build the particular
389: utility is up to date. (yacc, lex, etc...)
390: 3) cd ...path/to/util...
391: make cleandir
392: rm ...all obj directories...
393: make cleandir # yes, again
394: make obj
395: make depend && make
396:
397: Failsafe rebuild of the entire tree:
398: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
399: If you really want to make sure the source tree is clean and
1.2 mrg 400: ready for a build try the following. Note that sourcing /etc/mk.conf
401: (a make(1) Makefile) in this manner is not right, and will not work
402: for anyone who uses any make(1) features in /etc/mk.conf.
