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