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:
1.213 ! jmmv 19: 20100604:
! 20: The update of ATF to 0.9 causes old tests written in shell to fail
! 21: unless they are rebuilt. If you are building with MKUPDATE=yes,
! 22: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
! 23: trees by hand.
! 24:
1.211 tnozaki 25: 20100522:
1.212 mrg 26: Recent Xorg updates in xsrc/external/mit/ will cause various build
27: problems. Delete your entire DESTDIR and OBJDIR if you have any
28: build problems with xsrc.
29:
30: 20100522:
1.211 tnozaki 31: private section of <ctype.h> was splitted, and now mklocale(1)
32: include ctype_local.h, so you have to make cleandir tools/mklocale.
33:
1.210 christos 34: 20100520:
35: The location of the xkb compiled descriptions has changed. Please
36: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
37:
1.209 njoly 38: 20100222:
39: The shared objects file extension has been changed from .so to
40: .pico, in order to avoid conflicts with shared libraries names
41: libXX.so. All now stale regular .so files can be removed from
42: your object directories.
43:
1.208 roy 44: 20100204:
45: The termcap database has been removed from the sources,
46: but has not been marked obsolete so it is not removed
47: from the system when upgrading.
48: As such, you will need to remove them from your object
49: and destination directories.
50:
1.203 dyoung 51: 20091101:
1.205 dholland 52: After updating, it may be necessary to make the 'cleandir'
53: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
54: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
55: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 56:
1.202 mrg 57: 20091001:
1.206 dholland 58: On amd64 you must rebuild tools (to get the new binutils)
59: before building a kernel, or the build fails on cpufunc.S.
60:
61: 20091001:
1.202 mrg 62: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
63: symlink, failing the build. Delete the link, and the subdir
64: it is in, and retry your build.
65:
1.201 dsl 66: 20090718:
67: libc build changed so that strchr() provides the extra entry
68: point for index(). Update build of libc.a (and libc_pic.a)
69: may fail because the archive contains the unwanted index.o.
70: (Similarly for strrchr() and rindex().)
71:
1.198 mrg 72: 20090709:
73: Native Xorg was upgraded again. Builds will probably fail again
74: without a clean objdir, at least for src/external/mit/xorg.
75:
1.197 mrg 76: 20090616:
77: Native Xorg was upgraded. Builds will need a clean objdir for
78: src/external/mit/xorg. Upgrading a system from sets will not
79: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
80: subdirectory has been changed into a file, and this needs to
81: be manually "rm -r"'ed before installing xbase.tgz.
82:
1.195 perry 83: 20090501:
84: Several new functions were added to string.h/libc, and this
85: can cause autoconf problems during the tool build for people
86: who fail to clean out their tools objects properly. If you
87: note messages about stpcpy, stpncpy or strnlen accompanying a
88: failure during the tool build, clean out all your tools
89: objects and start again.
90:
1.194 mrg 91: 20090325:
92: The i386 port was switched to i486 default toolchain. This requires
93: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
94:
1.192 skrll 95: 20090126:
1.207 mbalmer 96: The __posix_fadvise50 system call changed assembly stub type. You
97: need to 'rm -f __posix_fadvise50.*' in the libc build directory
98: to avoid using the old assembly stub.
1.192 skrll 99:
1.191 joerg 100: 20090202:
101: pkg_install now depends on the pkgdb cache for automatic conflict
102: detection. It is recommented to rebuild the cache with
103: ``pkg_admin rebuild''.
104:
1.184 christos 105: 20090110:
106: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
107: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 108: This is needed even in the MODULAR kernel because there is
109: conditionally compiled code in rtsock.c.
1.184 christos 110: 2. make sure build.sh completes and the binaries in a chroot work
111: before installing.
112: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 113: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 114: are installed properly, and start building libraries first libc
115: and libutil, install them and then continue building all the
116: libraries in src/lib and src/gnu/lib and install them. Once
117: the new libraries are installed, you can restart the build.
118: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 119: rebuild the required packages to update their shared libraries.
120: Any package you rebuild will require rebuilding all the packages
121: that depend on it.
1.186 christos 122: 5. Next time you run pwd_mkdb with the new binary, the file
123: will be upgraded and it will not be backwards compatible.
1.190 apb 124: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
125: lastlogx(5)) have been versioned, and there is a heuristic
126: for utmp. You are better off removing the old files after
127: upgrading. The automated clearing of /var/run during
128: boot, and the automated rotating of files in /var/log by
129: newsyslog(8), may mean that you do not have to remove the
130: files manually.
131: 7. The optional accounting file (/var/account/acct, see
132: accton(8)) has not been versioned, and will need to be
133: removed. The automatic rotation of the accounting file by
134: /etc/daily limits the bad consequences of failure to remove
135: the file.
1.196 dholland 136: 8. Application software that writes time_t to binary files on
137: disk will break or need attention. Most notably: if you are
138: using PostgreSQL < 8.4, you need to dump your databases,
139: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 140:
1.183 pgoyette 141: 20081219:
142: config(1) has been updated, and one of the files it creates -
143: swapnetbsd.o - has changed format. You need to rebuild config
144: (done automatically by build.sh) and then you need to rerun
145: config on all kernel configuration files before rebuilding those
146: kernels.
147:
1.181 cube 148: 20081205:
149: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
150: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
151: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 152:
1.179 tsutsui 153: 20081122:
1.182 tsutsui 154: On i386, various kernel options(4) in GENERIC including
1.180 wiz 155: file systems have been disabled and moved into kernel modules.
156: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 157: following files as well as a new GENERIC kernel:
158:
159: - build and install kernel modules from src/sys/modules
160:
161: - install the latest bootloader, which will load a module
1.180 wiz 162: for the file system from which the kernel is loaded automatically
1.179 tsutsui 163:
1.180 wiz 164: If you have to load your kernel from a file system which is not of
165: the same type as the root file system, you have to load the necessary
166: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 167:
1.178 lukem 168: 20080827:
169: If you built and installed a libc from sources between
170: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
171: which results in false errors reported by lint(1).
172: Since this breaks the libc build itself, manual help is
1.180 wiz 173: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 174: $ (cd lib/libc && make MKLINT=no dependall install)
175:
1.177 christos 176: 20080813:
177: MKDEBUG build was broken because the .depend files did not know
178: about .go files. You need to remove all .depend files and rebuild.
179:
1.200 dholland 180: 20080802:
181: A regression in binary compatibility for pthread_mutex_t has
182: been fixed. Unfortunately, the price is breaking compatibility
183: for -current.
184:
185: Threaded programs (using libpthread) and C++ programs (using
186: libstdc++) compiled after 20070907 and before 20080802 need to
187: be recompiled.
188:
189: One way to find affected pkgsrc packages:
190:
191: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
192: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
193:
1.175 simonb 194: 20080731:
195: WAPBL (metadata journaling support) has been added, but at this
196: time isn't backwards compatible with pre-WAPBL aware kernels
197: and userland (fsck_ffs in particular). Please make sure you
198: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 199: especially an uncleanly mounted journaled filesystem. WAPBL
200: also requires the super block to be in the UFS2 format. You
201: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 202:
1.174 lukem 203: 20080721:
204: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
205: isn't defined.
206:
1.173 freza 207: 20080531:
208: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
209: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
210: utility needs to be rebuilt and reinstalled as older binaries
211: won't work correctly. The following sequence of commands:
212:
213: $ (cd sys/sys/ && nbmake-$arch includes)
214: $ (cd sbin/drvctl/ && nbmake-$arch clean)
215: $ (cd sbin/drvctl/ && nbmake-$arch all)
216:
217: leaves new drvctl utility in sbin/drvctl build directory.
218:
1.172 lukem 219: 20080503:
220: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
221:
1.171 he 222: 20080521:
223: For a while, unprivileged UPDATE builds would fail to
224: succeed at the checkflist stage, complaining that
225: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
226: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
227: If you already hit this problem, update the .mk file,
228: remove ${DESTDIR}/stand/<arch>, and re-run the build.
229:
1.174 lukem 230: 20080303:
231: Linker warnings are now fatal if $WARNS>0.
232:
1.170 christos 233: 20080126:
234: The posix_fadvise system call has been changed from an assembly
235: stub, to a c file that calls an assembly stub. You need to
236: 'rm -f posix_fadvise.* .depend' in the libc build directory to
237: avoid using the old assembly stub.
238:
1.168 joerg 239: 20071209:
240: The acpiec(4) driver has been split into two attachments. If you
241: get ACPI errors before the attachment, please update your kernel
1.169 wiz 242: configuration file appropriately or see GENERIC for more details.
1.168 joerg 243:
1.166 xtraeme 244: 20071115:
245: The it(4) driver has been renamed to itesio(4) and the old port
246: argument specified in the kernel configuration file is not valid
247: anymore. The itesio(4) driver now uses the Super I/O address port
248: rather than the EC address port. Please update your kernel
1.167 wiz 249: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 250:
1.165 jmmv 251: 20071028:
252: The pccons(4) driver has been removed from the NetBSD/shark port.
253: You need to update any custom kernel configuration file you have
254: to remove any references to pccons (which includes removing the
255: now useless XSERVER option) and replace them with the correct
256: entries for the wscons driver. See the GENERIC configuration file
257: for more details.
258:
1.164 gdt 259: 20070913:
260: A latent bug in dhclient/dhcpd that caused it to be unable to
261: enumerate interfaces was fixed. The bug began to cause
262: problems after 20070911 when the kernel's SIOCGIFCONF
263: implementation was repaired. From 20070529 to 20070911 racoon
264: could not enumerate interfaces. (These are noted because
265: normal kernel/userspace version matching hygiene is not
266: sufficient to avoid this problem.) Ensure that both kernel
267: and userland are from after 20070913.
268:
1.163 joerg 269: 20070703:
1.199 dholland 270: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
271: calls the target-specific strip program, and the logic to pass
272: down STRIP from make has been removed. This requires a
273: re-installation of tools.
1.163 joerg 274:
1.161 dsl 275: 20070422:
276: The way OS emulations lookup filenames inside the emulation root
277: has been changed. Rather than modify the pathname (and copy back
278: to userspace) namei() and lookup() directly check the emulation
279: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 280: root file system will be relative to that file system - unless they
1.161 dsl 281: start /../ this is useful when the emulated root is a real install
282: that has such links.
283: This might affect symlinks that have been added to reference outside
284: the emulated root.
285:
1.160 jmcneill 286: 20070412:
287: The pckbc driver on sgimips IP32 has been removed. Use macekbc
288: instead. See the GENERIC32_IP3x kernel configuration for an
289: example.
290:
1.159 gdt 291: 20070319:
292: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
293: on many platforms due to incorrect flags settings. If you
294: updated and built after about 20070315, do "nbmake-$arch
295: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
296: rebuild of object files that might have been built
297: incorrectly, and ensure that you have at least
298: src/lib/libc/Makefile 1.130.
299:
1.158 dbj 300: 20070210:
301: src/sys/sys/{sa.h,savar.h} were removed.
302: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
303: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
304: will allow dependencies on those files to get get rebuilt
305:
1.157 apb 306: 20070209:
307: The threading model was changed when the newlock2 branch
308: was merged to NetBSD-current. If you boot with a new
309: kernel (version 4.99.10), then you also need a new pthread
310: library (/usr/lib/libpthread.so.0.7). If you boot with
311: an old kernel, then you need the old pthread library
312: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
313: the pthread library in sync, old threaded applications should
314: continue to work with an old or new kernel. Note that named(8)
315: is the only threaded application in the base system.
316:
1.154 he 317: 20061214:
318: Following the move of string_to_flags() and flags_to_string()
319: from the bin/ls/ sources to libutil, users doing UPDATE builds
320: will need to do a "make cleandir" in
321: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
322: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 323: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
324: as the installation images in distrib/
1.154 he 325: in order to excise stale references to the old stat_flags.h header
326: file in the ls sources -- stat_flags.h has been removed.
327:
1.152 christos 328: 20061108:
329: The configure script used in the src/tools/gcc compiler has been
330: changed to indicate that our libc has ssp support built-in and
331: does not depend on -lssp and -lssp-nonshared. You'll need to
332: make clean in src/tools/gcc first to rebuild the compiler.
333:
1.151 rpaulo 334: 20061009:
335: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
336: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
337:
1.150 bjh21 338: 20060814:
339: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
340: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
341: kernel configuration for an example. X servers from the last
342: few years should cope.
343:
1.149 christos 344: 20060703:
345: MPACPI is no more. We always configure PCI interrupts using ACPI
346: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
347: to ACPI_SCANPCI. Thanks to work from fvdl.
348:
1.148 dogcow 349: 20060627:
350: socket(2) has changed, and its system call has been versioned.
351: For userlands with the old version of socket(2), make sure that
352: your kernel has 'options COMPAT_30' set, or else 'bad system call'
353: errors will result.
354:
1.1 abs 355: Hints for a more successful build:
356: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 357: Use build.sh, but do not use its "expert mode":
1.132 jmmv 358: This will automatically build the tools in the
1.123 jmc 359: correct order, and it will keep the tools and the
360: new build products from interfering with the running
361: system. This will allow you to ignore most of the
362: other advice in this file.
1.2 mrg 363: Build a new kernel first:
364: This makes sure that any new system calls or features
365: expected by the new userland will be present. This
366: helps to avoid critical errors when upgrading.
1.1 abs 367: Use object directories:
368: This helps to keep stale object
369: files from polluting the build if a Makefile "forgets"
370: about one. It also makes it easier to clean up after
371: a build. It's also necessary if you want to use the
372: same source tree for multiple machines.
1.123 jmc 373: To use object directories with build.sh:
374: a) invoke build.sh with the "-M" or "-O" options.
375: To use object directories without using build.sh:
1.1 abs 376: a) cd /usr/src ; make cleandir
1.2 mrg 377: b) Add "OBJMACHINE=yes" to /etc/mk.conf
378: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 379: d) cd /usr/src ; make build
1.2 mrg 380: Note that running "make obj" in a directory will create
381: in obj.$MACHINE directory.
1.1 abs 382: Build to a DESTDIR:
1.123 jmc 383: This helps to keep old installed files (especially libraries)
384: from interfering with the new build.
385: To build to a DESTDIR with build.sh, use the "-D" option.
386: To build to a DESTDIR without using build.sh, set the DESTDIR
387: environment variable before running make build. It should be
388: set to the pathname of an initially empty directory.
389: Problems: if you do not use build.sh, you might need to
390: update critical utilities without using DESTDIR since
391: nothing is executed from what is installed in DESTDIR.
392: (See critical utils, below.)
1.1 abs 393: Build often:
394: This keeps critical utilities current enough to not choke
395: on any other part of the source tree that depends on up to
1.123 jmc 396: date functionality. If you use build.sh, you should not have
397: this problem.
1.1 abs 398:
399: What to do if things don't work:
400: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
401: When things don't work there is usually a few things that commonly
402: should be done.
403: 1) make includes
404: This should be done automatically by make build.
405: 2) cd share/mk && make install
406: Again, automatically done by make build.
407:
408: Failsafe rebuild of a small part of the tree:
409: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
410: To make sure you rebuild something correctly you want to do
411: something like the following:
412: 1) Make sure the includes and .mk files are up to date.
413: 2) Make sure any program used to build the particular
414: utility is up to date. (yacc, lex, etc...)
