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:
1.211 ! tnozaki 19: 20100522:
! 20: private section of <ctype.h> was splitted, and now mklocale(1)
! 21: include ctype_local.h, so you have to make cleandir tools/mklocale.
! 22:
1.210 christos 23: 20100520:
24: The location of the xkb compiled descriptions has changed. Please
25: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
26:
27:
1.209 njoly 28: 20100222:
29: The shared objects file extension has been changed from .so to
30: .pico, in order to avoid conflicts with shared libraries names
31: libXX.so. All now stale regular .so files can be removed from
32: your object directories.
33:
1.208 roy 34: 20100204:
35: The termcap database has been removed from the sources,
36: but has not been marked obsolete so it is not removed
37: from the system when upgrading.
38: As such, you will need to remove them from your object
39: and destination directories.
40:
1.203 dyoung 41: 20091101:
1.205 dholland 42: After updating, it may be necessary to make the 'cleandir'
43: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
44: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
45: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 46:
1.202 mrg 47: 20091001:
1.206 dholland 48: On amd64 you must rebuild tools (to get the new binutils)
49: before building a kernel, or the build fails on cpufunc.S.
50:
51: 20091001:
1.202 mrg 52: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
53: symlink, failing the build. Delete the link, and the subdir
54: it is in, and retry your build.
55:
1.201 dsl 56: 20090718:
57: libc build changed so that strchr() provides the extra entry
58: point for index(). Update build of libc.a (and libc_pic.a)
59: may fail because the archive contains the unwanted index.o.
60: (Similarly for strrchr() and rindex().)
61:
1.198 mrg 62: 20090709:
63: Native Xorg was upgraded again. Builds will probably fail again
64: without a clean objdir, at least for src/external/mit/xorg.
65:
1.197 mrg 66: 20090616:
67: Native Xorg was upgraded. Builds will need a clean objdir for
68: src/external/mit/xorg. Upgrading a system from sets will not
69: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
70: subdirectory has been changed into a file, and this needs to
71: be manually "rm -r"'ed before installing xbase.tgz.
72:
1.195 perry 73: 20090501:
74: Several new functions were added to string.h/libc, and this
75: can cause autoconf problems during the tool build for people
76: who fail to clean out their tools objects properly. If you
77: note messages about stpcpy, stpncpy or strnlen accompanying a
78: failure during the tool build, clean out all your tools
79: objects and start again.
80:
1.194 mrg 81: 20090325:
82: The i386 port was switched to i486 default toolchain. This requires
83: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
84:
1.192 skrll 85: 20090126:
1.207 mbalmer 86: The __posix_fadvise50 system call changed assembly stub type. You
87: need to 'rm -f __posix_fadvise50.*' in the libc build directory
88: to avoid using the old assembly stub.
1.192 skrll 89:
1.191 joerg 90: 20090202:
91: pkg_install now depends on the pkgdb cache for automatic conflict
92: detection. It is recommented to rebuild the cache with
93: ``pkg_admin rebuild''.
94:
1.184 christos 95: 20090110:
96: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
97: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 98: This is needed even in the MODULAR kernel because there is
99: conditionally compiled code in rtsock.c.
1.184 christos 100: 2. make sure build.sh completes and the binaries in a chroot work
101: before installing.
102: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 103: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 104: are installed properly, and start building libraries first libc
105: and libutil, install them and then continue building all the
106: libraries in src/lib and src/gnu/lib and install them. Once
107: the new libraries are installed, you can restart the build.
108: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 109: rebuild the required packages to update their shared libraries.
110: Any package you rebuild will require rebuilding all the packages
111: that depend on it.
1.186 christos 112: 5. Next time you run pwd_mkdb with the new binary, the file
113: will be upgraded and it will not be backwards compatible.
1.190 apb 114: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
115: lastlogx(5)) have been versioned, and there is a heuristic
116: for utmp. You are better off removing the old files after
117: upgrading. The automated clearing of /var/run during
118: boot, and the automated rotating of files in /var/log by
119: newsyslog(8), may mean that you do not have to remove the
120: files manually.
121: 7. The optional accounting file (/var/account/acct, see
122: accton(8)) has not been versioned, and will need to be
123: removed. The automatic rotation of the accounting file by
124: /etc/daily limits the bad consequences of failure to remove
125: the file.
1.196 dholland 126: 8. Application software that writes time_t to binary files on
127: disk will break or need attention. Most notably: if you are
128: using PostgreSQL < 8.4, you need to dump your databases,
129: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 130:
1.183 pgoyette 131: 20081219:
132: config(1) has been updated, and one of the files it creates -
133: swapnetbsd.o - has changed format. You need to rebuild config
134: (done automatically by build.sh) and then you need to rerun
135: config on all kernel configuration files before rebuilding those
136: kernels.
137:
1.181 cube 138: 20081205:
139: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
140: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
141: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 142:
1.179 tsutsui 143: 20081122:
1.182 tsutsui 144: On i386, various kernel options(4) in GENERIC including
1.180 wiz 145: file systems have been disabled and moved into kernel modules.
146: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 147: following files as well as a new GENERIC kernel:
148:
149: - build and install kernel modules from src/sys/modules
150:
151: - install the latest bootloader, which will load a module
1.180 wiz 152: for the file system from which the kernel is loaded automatically
1.179 tsutsui 153:
1.180 wiz 154: If you have to load your kernel from a file system which is not of
155: the same type as the root file system, you have to load the necessary
156: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 157:
1.178 lukem 158: 20080827:
159: If you built and installed a libc from sources between
160: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
161: which results in false errors reported by lint(1).
162: Since this breaks the libc build itself, manual help is
1.180 wiz 163: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 164: $ (cd lib/libc && make MKLINT=no dependall install)
165:
1.177 christos 166: 20080813:
167: MKDEBUG build was broken because the .depend files did not know
168: about .go files. You need to remove all .depend files and rebuild.
169:
1.200 dholland 170: 20080802:
171: A regression in binary compatibility for pthread_mutex_t has
172: been fixed. Unfortunately, the price is breaking compatibility
173: for -current.
174:
175: Threaded programs (using libpthread) and C++ programs (using
176: libstdc++) compiled after 20070907 and before 20080802 need to
177: be recompiled.
178:
179: One way to find affected pkgsrc packages:
180:
181: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
182: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
183:
1.175 simonb 184: 20080731:
185: WAPBL (metadata journaling support) has been added, but at this
186: time isn't backwards compatible with pre-WAPBL aware kernels
187: and userland (fsck_ffs in particular). Please make sure you
188: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 189: especially an uncleanly mounted journaled filesystem. WAPBL
190: also requires the super block to be in the UFS2 format. You
191: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 192:
1.174 lukem 193: 20080721:
194: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
195: isn't defined.
196:
1.173 freza 197: 20080531:
198: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
199: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
200: utility needs to be rebuilt and reinstalled as older binaries
201: won't work correctly. The following sequence of commands:
202:
203: $ (cd sys/sys/ && nbmake-$arch includes)
204: $ (cd sbin/drvctl/ && nbmake-$arch clean)
205: $ (cd sbin/drvctl/ && nbmake-$arch all)
206:
207: leaves new drvctl utility in sbin/drvctl build directory.
208:
1.172 lukem 209: 20080503:
210: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
211:
1.171 he 212: 20080521:
213: For a while, unprivileged UPDATE builds would fail to
214: succeed at the checkflist stage, complaining that
215: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
216: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
217: If you already hit this problem, update the .mk file,
218: remove ${DESTDIR}/stand/<arch>, and re-run the build.
219:
1.174 lukem 220: 20080303:
221: Linker warnings are now fatal if $WARNS>0.
222:
1.170 christos 223: 20080126:
224: The posix_fadvise system call has been changed from an assembly
225: stub, to a c file that calls an assembly stub. You need to
226: 'rm -f posix_fadvise.* .depend' in the libc build directory to
227: avoid using the old assembly stub.
228:
1.168 joerg 229: 20071209:
230: The acpiec(4) driver has been split into two attachments. If you
231: get ACPI errors before the attachment, please update your kernel
1.169 wiz 232: configuration file appropriately or see GENERIC for more details.
1.168 joerg 233:
1.166 xtraeme 234: 20071115:
235: The it(4) driver has been renamed to itesio(4) and the old port
236: argument specified in the kernel configuration file is not valid
237: anymore. The itesio(4) driver now uses the Super I/O address port
238: rather than the EC address port. Please update your kernel
1.167 wiz 239: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 240:
1.165 jmmv 241: 20071028:
242: The pccons(4) driver has been removed from the NetBSD/shark port.
243: You need to update any custom kernel configuration file you have
244: to remove any references to pccons (which includes removing the
245: now useless XSERVER option) and replace them with the correct
246: entries for the wscons driver. See the GENERIC configuration file
247: for more details.
248:
1.164 gdt 249: 20070913:
250: A latent bug in dhclient/dhcpd that caused it to be unable to
251: enumerate interfaces was fixed. The bug began to cause
252: problems after 20070911 when the kernel's SIOCGIFCONF
253: implementation was repaired. From 20070529 to 20070911 racoon
254: could not enumerate interfaces. (These are noted because
255: normal kernel/userspace version matching hygiene is not
256: sufficient to avoid this problem.) Ensure that both kernel
257: and userland are from after 20070913.
258:
1.163 joerg 259: 20070703:
1.199 dholland 260: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
261: calls the target-specific strip program, and the logic to pass
262: down STRIP from make has been removed. This requires a
263: re-installation of tools.
1.163 joerg 264:
1.161 dsl 265: 20070422:
266: The way OS emulations lookup filenames inside the emulation root
267: has been changed. Rather than modify the pathname (and copy back
268: to userspace) namei() and lookup() directly check the emulation
269: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 270: root file system will be relative to that file system - unless they
1.161 dsl 271: start /../ this is useful when the emulated root is a real install
272: that has such links.
273: This might affect symlinks that have been added to reference outside
274: the emulated root.
275:
1.160 jmcneill 276: 20070412:
277: The pckbc driver on sgimips IP32 has been removed. Use macekbc
278: instead. See the GENERIC32_IP3x kernel configuration for an
279: example.
280:
1.159 gdt 281: 20070319:
282: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
283: on many platforms due to incorrect flags settings. If you
284: updated and built after about 20070315, do "nbmake-$arch
285: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
286: rebuild of object files that might have been built
287: incorrectly, and ensure that you have at least
288: src/lib/libc/Makefile 1.130.
289:
1.158 dbj 290: 20070210:
291: src/sys/sys/{sa.h,savar.h} were removed.
292: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
293: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
294: will allow dependencies on those files to get get rebuilt
295:
1.157 apb 296: 20070209:
297: The threading model was changed when the newlock2 branch
298: was merged to NetBSD-current. If you boot with a new
299: kernel (version 4.99.10), then you also need a new pthread
300: library (/usr/lib/libpthread.so.0.7). If you boot with
301: an old kernel, then you need the old pthread library
302: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
303: the pthread library in sync, old threaded applications should
304: continue to work with an old or new kernel. Note that named(8)
305: is the only threaded application in the base system.
306:
1.154 he 307: 20061214:
308: Following the move of string_to_flags() and flags_to_string()
309: from the bin/ls/ sources to libutil, users doing UPDATE builds
310: will need to do a "make cleandir" in
311: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
312: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 313: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
314: as the installation images in distrib/
1.154 he 315: in order to excise stale references to the old stat_flags.h header
316: file in the ls sources -- stat_flags.h has been removed.
317:
1.152 christos 318: 20061108:
319: The configure script used in the src/tools/gcc compiler has been
320: changed to indicate that our libc has ssp support built-in and
321: does not depend on -lssp and -lssp-nonshared. You'll need to
322: make clean in src/tools/gcc first to rebuild the compiler.
323:
1.151 rpaulo 324: 20061009:
325: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
326: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
327:
1.150 bjh21 328: 20060814:
329: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
330: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
331: kernel configuration for an example. X servers from the last
332: few years should cope.
333:
1.149 christos 334: 20060703:
335: MPACPI is no more. We always configure PCI interrupts using ACPI
336: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
337: to ACPI_SCANPCI. Thanks to work from fvdl.
338:
1.148 dogcow 339: 20060627:
340: socket(2) has changed, and its system call has been versioned.
341: For userlands with the old version of socket(2), make sure that
342: your kernel has 'options COMPAT_30' set, or else 'bad system call'
343: errors will result.
344:
1.1 abs 345: Hints for a more successful build:
346: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 347: Use build.sh, but do not use its "expert mode":
1.132 jmmv 348: This will automatically build the tools in the
1.123 jmc 349: correct order, and it will keep the tools and the
350: new build products from interfering with the running
351: system. This will allow you to ignore most of the
352: other advice in this file.
1.2 mrg 353: Build a new kernel first:
354: This makes sure that any new system calls or features
355: expected by the new userland will be present. This
356: helps to avoid critical errors when upgrading.
1.1 abs 357: Use object directories:
358: This helps to keep stale object
359: files from polluting the build if a Makefile "forgets"
360: about one. It also makes it easier to clean up after
361: a build. It's also necessary if you want to use the
362: same source tree for multiple machines.
1.123 jmc 363: To use object directories with build.sh:
364: a) invoke build.sh with the "-M" or "-O" options.
365: To use object directories without using build.sh:
1.1 abs 366: a) cd /usr/src ; make cleandir
1.2 mrg 367: b) Add "OBJMACHINE=yes" to /etc/mk.conf
368: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 369: d) cd /usr/src ; make build
1.2 mrg 370: Note that running "make obj" in a directory will create
371: in obj.$MACHINE directory.
1.1 abs 372: Build to a DESTDIR:
1.123 jmc 373: This helps to keep old installed files (especially libraries)
374: from interfering with the new build.
375: To build to a DESTDIR with build.sh, use the "-D" option.
376: To build to a DESTDIR without using build.sh, set the DESTDIR
377: environment variable before running make build. It should be
378: set to the pathname of an initially empty directory.
379: Problems: if you do not use build.sh, you might need to
380: update critical utilities without using DESTDIR since
381: nothing is executed from what is installed in DESTDIR.
382: (See critical utils, below.)
1.1 abs 383: Build often:
384: This keeps critical utilities current enough to not choke
385: on any other part of the source tree that depends on up to
1.123 jmc 386: date functionality. If you use build.sh, you should not have
387: this problem.
1.1 abs 388:
389: What to do if things don't work:
390: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
391: When things don't work there is usually a few things that commonly
392: should be done.
393: 1) make includes
394: This should be done automatically by make build.
395: 2) cd share/mk && make install
396: Again, automatically done by make build.
397:
398: Failsafe rebuild of a small part of the tree:
399: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
400: To make sure you rebuild something correctly you want to do
401: something like the following:
402: 1) Make sure the includes and .mk files are up to date.
403: 2) Make sure any program used to build the particular
404: utility is up to date. (yacc, lex, etc...)
405: 3) cd ...path/to/util...
406: make cleandir
407: rm ...all obj directories...
408: make cleandir # yes, again
409: make obj
410: make depend && make
411:
412: Failsafe rebuild of the entire tree:
413: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
414: If you really want to make sure the source tree is clean and
1.2 mrg 415: ready for a build try the following. Note that sourcing /etc/mk.conf
416: (a make(1) Makefile) in this manner is not right, and will not work
417: for anyone who uses any make(1) features in /etc/mk.conf.
1.1 abs 418:
