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:
1.211 tnozaki 19: 20100522:
1.212 ! mrg 20: Recent Xorg updates in xsrc/external/mit/ will cause various build
! 21: problems. Delete your entire DESTDIR and OBJDIR if you have any
! 22: build problems with xsrc.
! 23:
! 24: 20100522:
1.211 tnozaki 25: private section of <ctype.h> was splitted, and now mklocale(1)
26: include ctype_local.h, so you have to make cleandir tools/mklocale.
27:
1.210 christos 28: 20100520:
29: The location of the xkb compiled descriptions has changed. Please
30: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
31:
1.209 njoly 32: 20100222:
33: The shared objects file extension has been changed from .so to
34: .pico, in order to avoid conflicts with shared libraries names
35: libXX.so. All now stale regular .so files can be removed from
36: your object directories.
37:
1.208 roy 38: 20100204:
39: The termcap database has been removed from the sources,
40: but has not been marked obsolete so it is not removed
41: from the system when upgrading.
42: As such, you will need to remove them from your object
43: and destination directories.
44:
1.203 dyoung 45: 20091101:
1.205 dholland 46: After updating, it may be necessary to make the 'cleandir'
47: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
48: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
49: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 50:
1.202 mrg 51: 20091001:
1.206 dholland 52: On amd64 you must rebuild tools (to get the new binutils)
53: before building a kernel, or the build fails on cpufunc.S.
54:
55: 20091001:
1.202 mrg 56: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
57: symlink, failing the build. Delete the link, and the subdir
58: it is in, and retry your build.
59:
1.201 dsl 60: 20090718:
61: libc build changed so that strchr() provides the extra entry
62: point for index(). Update build of libc.a (and libc_pic.a)
63: may fail because the archive contains the unwanted index.o.
64: (Similarly for strrchr() and rindex().)
65:
1.198 mrg 66: 20090709:
67: Native Xorg was upgraded again. Builds will probably fail again
68: without a clean objdir, at least for src/external/mit/xorg.
69:
1.197 mrg 70: 20090616:
71: Native Xorg was upgraded. Builds will need a clean objdir for
72: src/external/mit/xorg. Upgrading a system from sets will not
73: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
74: subdirectory has been changed into a file, and this needs to
75: be manually "rm -r"'ed before installing xbase.tgz.
76:
1.195 perry 77: 20090501:
78: Several new functions were added to string.h/libc, and this
79: can cause autoconf problems during the tool build for people
80: who fail to clean out their tools objects properly. If you
81: note messages about stpcpy, stpncpy or strnlen accompanying a
82: failure during the tool build, clean out all your tools
83: objects and start again.
84:
1.194 mrg 85: 20090325:
86: The i386 port was switched to i486 default toolchain. This requires
87: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
88:
1.192 skrll 89: 20090126:
1.207 mbalmer 90: The __posix_fadvise50 system call changed assembly stub type. You
91: need to 'rm -f __posix_fadvise50.*' in the libc build directory
92: to avoid using the old assembly stub.
1.192 skrll 93:
1.191 joerg 94: 20090202:
95: pkg_install now depends on the pkgdb cache for automatic conflict
96: detection. It is recommented to rebuild the cache with
97: ``pkg_admin rebuild''.
98:
1.184 christos 99: 20090110:
100: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
101: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 102: This is needed even in the MODULAR kernel because there is
103: conditionally compiled code in rtsock.c.
1.184 christos 104: 2. make sure build.sh completes and the binaries in a chroot work
105: before installing.
106: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 107: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 108: are installed properly, and start building libraries first libc
109: and libutil, install them and then continue building all the
110: libraries in src/lib and src/gnu/lib and install them. Once
111: the new libraries are installed, you can restart the build.
112: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 113: rebuild the required packages to update their shared libraries.
114: Any package you rebuild will require rebuilding all the packages
115: that depend on it.
1.186 christos 116: 5. Next time you run pwd_mkdb with the new binary, the file
117: will be upgraded and it will not be backwards compatible.
1.190 apb 118: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
119: lastlogx(5)) have been versioned, and there is a heuristic
120: for utmp. You are better off removing the old files after
121: upgrading. The automated clearing of /var/run during
122: boot, and the automated rotating of files in /var/log by
123: newsyslog(8), may mean that you do not have to remove the
124: files manually.
125: 7. The optional accounting file (/var/account/acct, see
126: accton(8)) has not been versioned, and will need to be
127: removed. The automatic rotation of the accounting file by
128: /etc/daily limits the bad consequences of failure to remove
129: the file.
1.196 dholland 130: 8. Application software that writes time_t to binary files on
131: disk will break or need attention. Most notably: if you are
132: using PostgreSQL < 8.4, you need to dump your databases,
133: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 134:
1.183 pgoyette 135: 20081219:
136: config(1) has been updated, and one of the files it creates -
137: swapnetbsd.o - has changed format. You need to rebuild config
138: (done automatically by build.sh) and then you need to rerun
139: config on all kernel configuration files before rebuilding those
140: kernels.
141:
1.181 cube 142: 20081205:
143: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
144: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
145: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 146:
1.179 tsutsui 147: 20081122:
1.182 tsutsui 148: On i386, various kernel options(4) in GENERIC including
1.180 wiz 149: file systems have been disabled and moved into kernel modules.
150: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 151: following files as well as a new GENERIC kernel:
152:
153: - build and install kernel modules from src/sys/modules
154:
155: - install the latest bootloader, which will load a module
1.180 wiz 156: for the file system from which the kernel is loaded automatically
1.179 tsutsui 157:
1.180 wiz 158: If you have to load your kernel from a file system which is not of
159: the same type as the root file system, you have to load the necessary
160: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 161:
1.178 lukem 162: 20080827:
163: If you built and installed a libc from sources between
164: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
165: which results in false errors reported by lint(1).
166: Since this breaks the libc build itself, manual help is
1.180 wiz 167: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 168: $ (cd lib/libc && make MKLINT=no dependall install)
169:
1.177 christos 170: 20080813:
171: MKDEBUG build was broken because the .depend files did not know
172: about .go files. You need to remove all .depend files and rebuild.
173:
1.200 dholland 174: 20080802:
175: A regression in binary compatibility for pthread_mutex_t has
176: been fixed. Unfortunately, the price is breaking compatibility
177: for -current.
178:
179: Threaded programs (using libpthread) and C++ programs (using
180: libstdc++) compiled after 20070907 and before 20080802 need to
181: be recompiled.
182:
183: One way to find affected pkgsrc packages:
184:
185: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
186: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
187:
1.175 simonb 188: 20080731:
189: WAPBL (metadata journaling support) has been added, but at this
190: time isn't backwards compatible with pre-WAPBL aware kernels
191: and userland (fsck_ffs in particular). Please make sure you
192: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 193: especially an uncleanly mounted journaled filesystem. WAPBL
194: also requires the super block to be in the UFS2 format. You
195: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 196:
1.174 lukem 197: 20080721:
198: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
199: isn't defined.
200:
1.173 freza 201: 20080531:
202: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
203: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
204: utility needs to be rebuilt and reinstalled as older binaries
205: won't work correctly. The following sequence of commands:
206:
207: $ (cd sys/sys/ && nbmake-$arch includes)
208: $ (cd sbin/drvctl/ && nbmake-$arch clean)
209: $ (cd sbin/drvctl/ && nbmake-$arch all)
210:
211: leaves new drvctl utility in sbin/drvctl build directory.
212:
1.172 lukem 213: 20080503:
214: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
215:
1.171 he 216: 20080521:
217: For a while, unprivileged UPDATE builds would fail to
218: succeed at the checkflist stage, complaining that
219: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
220: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
221: If you already hit this problem, update the .mk file,
222: remove ${DESTDIR}/stand/<arch>, and re-run the build.
223:
1.174 lukem 224: 20080303:
225: Linker warnings are now fatal if $WARNS>0.
226:
1.170 christos 227: 20080126:
228: The posix_fadvise system call has been changed from an assembly
229: stub, to a c file that calls an assembly stub. You need to
230: 'rm -f posix_fadvise.* .depend' in the libc build directory to
231: avoid using the old assembly stub.
232:
1.168 joerg 233: 20071209:
234: The acpiec(4) driver has been split into two attachments. If you
235: get ACPI errors before the attachment, please update your kernel
1.169 wiz 236: configuration file appropriately or see GENERIC for more details.
1.168 joerg 237:
1.166 xtraeme 238: 20071115:
239: The it(4) driver has been renamed to itesio(4) and the old port
240: argument specified in the kernel configuration file is not valid
241: anymore. The itesio(4) driver now uses the Super I/O address port
242: rather than the EC address port. Please update your kernel
1.167 wiz 243: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 244:
1.165 jmmv 245: 20071028:
246: The pccons(4) driver has been removed from the NetBSD/shark port.
247: You need to update any custom kernel configuration file you have
248: to remove any references to pccons (which includes removing the
249: now useless XSERVER option) and replace them with the correct
250: entries for the wscons driver. See the GENERIC configuration file
251: for more details.
252:
1.164 gdt 253: 20070913:
254: A latent bug in dhclient/dhcpd that caused it to be unable to
255: enumerate interfaces was fixed. The bug began to cause
256: problems after 20070911 when the kernel's SIOCGIFCONF
257: implementation was repaired. From 20070529 to 20070911 racoon
258: could not enumerate interfaces. (These are noted because
259: normal kernel/userspace version matching hygiene is not
260: sufficient to avoid this problem.) Ensure that both kernel
261: and userland are from after 20070913.
262:
1.163 joerg 263: 20070703:
1.199 dholland 264: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
265: calls the target-specific strip program, and the logic to pass
266: down STRIP from make has been removed. This requires a
267: re-installation of tools.
1.163 joerg 268:
1.161 dsl 269: 20070422:
270: The way OS emulations lookup filenames inside the emulation root
271: has been changed. Rather than modify the pathname (and copy back
272: to userspace) namei() and lookup() directly check the emulation
273: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 274: root file system will be relative to that file system - unless they
1.161 dsl 275: start /../ this is useful when the emulated root is a real install
276: that has such links.
277: This might affect symlinks that have been added to reference outside
278: the emulated root.
279:
1.160 jmcneill 280: 20070412:
281: The pckbc driver on sgimips IP32 has been removed. Use macekbc
282: instead. See the GENERIC32_IP3x kernel configuration for an
283: example.
284:
1.159 gdt 285: 20070319:
286: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
287: on many platforms due to incorrect flags settings. If you
288: updated and built after about 20070315, do "nbmake-$arch
289: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
290: rebuild of object files that might have been built
291: incorrectly, and ensure that you have at least
292: src/lib/libc/Makefile 1.130.
293:
1.158 dbj 294: 20070210:
295: src/sys/sys/{sa.h,savar.h} were removed.
296: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
297: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
298: will allow dependencies on those files to get get rebuilt
299:
1.157 apb 300: 20070209:
301: The threading model was changed when the newlock2 branch
302: was merged to NetBSD-current. If you boot with a new
303: kernel (version 4.99.10), then you also need a new pthread
304: library (/usr/lib/libpthread.so.0.7). If you boot with
305: an old kernel, then you need the old pthread library
306: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
307: the pthread library in sync, old threaded applications should
308: continue to work with an old or new kernel. Note that named(8)
309: is the only threaded application in the base system.
310:
1.154 he 311: 20061214:
312: Following the move of string_to_flags() and flags_to_string()
313: from the bin/ls/ sources to libutil, users doing UPDATE builds
314: will need to do a "make cleandir" in
315: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
316: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 317: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
318: as the installation images in distrib/
1.154 he 319: in order to excise stale references to the old stat_flags.h header
320: file in the ls sources -- stat_flags.h has been removed.
321:
1.152 christos 322: 20061108:
323: The configure script used in the src/tools/gcc compiler has been
324: changed to indicate that our libc has ssp support built-in and
325: does not depend on -lssp and -lssp-nonshared. You'll need to
326: make clean in src/tools/gcc first to rebuild the compiler.
327:
1.151 rpaulo 328: 20061009:
329: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
330: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
331:
1.150 bjh21 332: 20060814:
333: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
334: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
335: kernel configuration for an example. X servers from the last
336: few years should cope.
337:
1.149 christos 338: 20060703:
339: MPACPI is no more. We always configure PCI interrupts using ACPI
340: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
341: to ACPI_SCANPCI. Thanks to work from fvdl.
342:
1.148 dogcow 343: 20060627:
344: socket(2) has changed, and its system call has been versioned.
345: For userlands with the old version of socket(2), make sure that
346: your kernel has 'options COMPAT_30' set, or else 'bad system call'
347: errors will result.
348:
1.1 abs 349: Hints for a more successful build:
350: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 351: Use build.sh, but do not use its "expert mode":
1.132 jmmv 352: This will automatically build the tools in the
1.123 jmc 353: correct order, and it will keep the tools and the
354: new build products from interfering with the running
355: system. This will allow you to ignore most of the
356: other advice in this file.
1.2 mrg 357: Build a new kernel first:
358: This makes sure that any new system calls or features
359: expected by the new userland will be present. This
360: helps to avoid critical errors when upgrading.
1.1 abs 361: Use object directories:
362: This helps to keep stale object
363: files from polluting the build if a Makefile "forgets"
364: about one. It also makes it easier to clean up after
365: a build. It's also necessary if you want to use the
366: same source tree for multiple machines.
1.123 jmc 367: To use object directories with build.sh:
368: a) invoke build.sh with the "-M" or "-O" options.
369: To use object directories without using build.sh:
1.1 abs 370: a) cd /usr/src ; make cleandir
1.2 mrg 371: b) Add "OBJMACHINE=yes" to /etc/mk.conf
372: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 373: d) cd /usr/src ; make build
1.2 mrg 374: Note that running "make obj" in a directory will create
375: in obj.$MACHINE directory.
1.1 abs 376: Build to a DESTDIR:
1.123 jmc 377: This helps to keep old installed files (especially libraries)
378: from interfering with the new build.
379: To build to a DESTDIR with build.sh, use the "-D" option.
380: To build to a DESTDIR without using build.sh, set the DESTDIR
381: environment variable before running make build. It should be
382: set to the pathname of an initially empty directory.
383: Problems: if you do not use build.sh, you might need to
384: update critical utilities without using DESTDIR since
385: nothing is executed from what is installed in DESTDIR.
386: (See critical utils, below.)
1.1 abs 387: Build often:
388: This keeps critical utilities current enough to not choke
389: on any other part of the source tree that depends on up to
1.123 jmc 390: date functionality. If you use build.sh, you should not have
391: this problem.
1.1 abs 392:
393: What to do if things don't work:
394: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
395: When things don't work there is usually a few things that commonly
396: should be done.
397: 1) make includes
398: This should be done automatically by make build.
399: 2) cd share/mk && make install
400: Again, automatically done by make build.
401:
402: Failsafe rebuild of a small part of the tree:
403: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
404: To make sure you rebuild something correctly you want to do
405: something like the following:
406: 1) Make sure the includes and .mk files are up to date.
407: 2) Make sure any program used to build the particular
408: utility is up to date. (yacc, lex, etc...)
409: 3) cd ...path/to/util...
410: make cleandir
411: rm ...all obj directories...
412: make cleandir # yes, again
413: make obj
414: make depend && make
415:
416: Failsafe rebuild of the entire tree:

482: (If you built the tree without "make obj" in the past, obsolete files
483: may remain. The command tries to clean everything up)
