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: ^^^^^^^^^^^^^^^
1.230 tls 18:
1.248 ! mrg 19: 20131128:
! 20: The MPC and MPFR sources were updated, and builds may require their
! 21: tools and in-tree directories cleaned for successful updates.
! 22:
1.246 martin 23: 20130605:
1.247 spz 24: The kernel option FAST_IPSEC no longer exists, it's been renamed
25: to IPSEC (and the older IPSEC version removed).
26:
27: 20130605:
1.246 martin 28: Previous freetype installations eroneously installed private
29: header files. If you are building against a non-empty $DESTDIR,
30: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
31:
1.245 mrg 32: 20130531:
33: The xdm update may cause build failure due to xdm.man being
34: in the obj tree. Make sure to ensure any like this:
35: nbmake: nbmake: don't know how to make xdm.man. Stop
36: is fixed by deleting the xdm.man in the obj tree.
37:
1.244 mrg 38: 20130530:
39: Updates of many xsrc packages will leave old .pc files around.
40: Best to clean out the xsrc objdir entirely before rebuilds.
41:
1.242 christos 42: 20130301:
43: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 44: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 45:
1.238 dholland 46: 20120726:
1.241 wiz 47: The update of OpenSSL requires cleaning both the OpenSSL build
48: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 49: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 50: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 51: cause third-party software to link incorrectly and/or crash.
1.238 dholland 52:
1.237 wiz 53: 20120507:
1.241 wiz 54: The database schema for makemandb was changed. You will
1.237 wiz 55: need to update the database using 'makemandb -f' or wait
56: for the next weekly run to fix it.
57:
1.236 bsh 58: 20120319:
59: sys/conf/Makefile.kern.inc has been modified to adjust the
60: size of db_symtab automatically. You need to update dbsym in
61: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
62: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
63: mk.conf.
64:
1.235 joerg 65: 20120216:
1.241 wiz 66: Default for MKCATPAGES changed to NO. Update builds will fail
67: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 68: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 69: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 70: the next run of weekly will fix it.
1.233 joerg 71:
1.232 christos 72: 20111227:
73: If you built between 20111225 and 20111227 you need to remove
74: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
75: bump has been reverted.
76:
1.231 tls 77: 20111125:
78: The "rnd" pseudodevice has been added to sys/conf/std, which
79: means it should no longer be explicitly listed in kernel
80: configuration files. The line "pseudo-device rnd" should be
81: removed from any custom kernel config files users may have.
82:
1.230 tls 83: 20111119:
84: A problem with the datastructures used by the rndctl(8)
85: utility (pointers in datastructures in an array, making 32->64
86: bit compatibility very painful) has been fixed in a
87: non-backwards-compatible way. If you replace your kernel,
88: replace your rndctl executable too.
1.241 wiz 89:
1.229 jym 90: 20111001:
91: the prop_*_send_syscall() functions from proplib(3) have been
92: changed and their new version is not backward compatible with the old
1.241 wiz 93: one. So ensure that all consumers of these functions (currently:
1.229 jym 94: quota2 code and its tests) are updated together with the new lib.
95:
1.228 mrg 96: 20110817:
97: sparc has been changed to use GCC 4.5.3, so any objdir or
98: DESTDIR for them should be deleted before updating.
99:
1.227 riastrad 100: 20110806:
101: i386 and amd64 have been changed to use GCC 4.5.3, so any
102: objdir or DESTDIR for them should be deleted before updating.
103:
1.226 mrg 104: 20110805:
105: The update to GCC 4.5.3 requires a non-trivial portion of
106: the tree to be cleaned. Best to delete both objdir and
107: DESTDIR before running this update. So far, only the
108: sparc64, mips and powerpc platforms have changed.
109:
1.225 matt 110: 20110803:
1.241 wiz 111: The layout of external/public-domain/xz has changed. To do an
1.225 matt 112: update build you will have to remove the contents of the OBJDIR
113: for external/public-domain/xz/bin by hand as the xz entry there
114: is now a directory.
115:
1.223 joerg 116: 20110410:
1.241 wiz 117: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 118: update build you have to clean both tools/binutils and
119: tools/gcc by hand.
1.223 joerg 120:
1.222 plunky 121: 20110328:
122: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 123: ordering issues with "make all". It may be necessary to remove
1.222 plunky 124: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
125: if your update build fails, as the "Xorg" entry there is now a
126: directory.
127:
1.220 joerg 128: 20110121:
1.221 lukem 129: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 130: the build of individual parts of the tree. This is handled
131: correctly by build.sh. Manual builds have to update /usr/share/mk
132: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 133:
1.217 jruoho 134: 20101217:
135: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 136: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 137: group(5) in order to make the program work with existing setups.
138:
1.216 christos 139: 20101125:
140: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 141: variables with names that contain '='. Revision 1.18 of env.c
142: assumed that this was allowed. Installing a new libc with an
1.216 christos 143: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
144: break which affects the autoconf tests for dependency finding,
145: so building gcc will end up printing:
146: checking dependency style of gcc... none
147: configure: error: no usable dependency style found
148: Fix it by rebuilding and re-installing env.
1.138 lukem 149:
1.215 mrg 150: 20101119:
151: Recent Xorg updates in xsrc/external/mit/ may cause various build
152: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
153: have any build problems with xsrc, or problems with mismatched
154: versions between xorg-server and drivers.
155:
1.213 jmmv 156: 20100604:
157: The update of ATF to 0.9 causes old tests written in shell to fail
158: unless they are rebuilt. If you are building with MKUPDATE=yes,
159: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
160: trees by hand.
161:
1.211 tnozaki 162: 20100522:
1.212 mrg 163: Recent Xorg updates in xsrc/external/mit/ will cause various build
164: problems. Delete your entire DESTDIR and OBJDIR if you have any
165: build problems with xsrc.
166:
167: 20100522:
1.211 tnozaki 168: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 169: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 170:
1.210 christos 171: 20100520:
1.241 wiz 172: The location of the xkb compiled descriptions has changed. Please
1.210 christos 173: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
174:
1.209 njoly 175: 20100222:
176: The shared objects file extension has been changed from .so to
177: .pico, in order to avoid conflicts with shared libraries names
178: libXX.so. All now stale regular .so files can be removed from
179: your object directories.
180:
1.208 roy 181: 20100204:
182: The termcap database has been removed from the sources,
183: but has not been marked obsolete so it is not removed
184: from the system when upgrading.
185: As such, you will need to remove them from your object
186: and destination directories.
187:
1.203 dyoung 188: 20091101:
1.205 dholland 189: After updating, it may be necessary to make the 'cleandir'
190: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
191: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
192: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 193:
1.202 mrg 194: 20091001:
1.206 dholland 195: On amd64 you must rebuild tools (to get the new binutils)
196: before building a kernel, or the build fails on cpufunc.S.
197:
198: 20091001:
1.202 mrg 199: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
200: symlink, failing the build. Delete the link, and the subdir
201: it is in, and retry your build.
202:
1.201 dsl 203: 20090718:
204: libc build changed so that strchr() provides the extra entry
1.241 wiz 205: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 206: may fail because the archive contains the unwanted index.o.
207: (Similarly for strrchr() and rindex().)
208:
1.198 mrg 209: 20090709:
210: Native Xorg was upgraded again. Builds will probably fail again
211: without a clean objdir, at least for src/external/mit/xorg.
212:
1.197 mrg 213: 20090616:
214: Native Xorg was upgraded. Builds will need a clean objdir for
215: src/external/mit/xorg. Upgrading a system from sets will not
216: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
217: subdirectory has been changed into a file, and this needs to
218: be manually "rm -r"'ed before installing xbase.tgz.
219:
1.195 perry 220: 20090501:
221: Several new functions were added to string.h/libc, and this
222: can cause autoconf problems during the tool build for people
1.241 wiz 223: who fail to clean out their tools objects properly. If you
1.195 perry 224: note messages about stpcpy, stpncpy or strnlen accompanying a
225: failure during the tool build, clean out all your tools
226: objects and start again.
227:
1.194 mrg 228: 20090325:
229: The i386 port was switched to i486 default toolchain. This requires
230: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
231:
1.192 skrll 232: 20090126:
1.241 wiz 233: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 234: need to 'rm -f __posix_fadvise50.*' in the libc build directory
235: to avoid using the old assembly stub.
1.192 skrll 236:
1.191 joerg 237: 20090202:
238: pkg_install now depends on the pkgdb cache for automatic conflict
239: detection. It is recommented to rebuild the cache with
240: ``pkg_admin rebuild''.
241:
1.184 christos 242: 20090110:
1.241 wiz 243: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
244: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 245: This is needed even in the MODULAR kernel because there is
246: conditionally compiled code in rtsock.c.
1.184 christos 247: 2. make sure build.sh completes and the binaries in a chroot work
248: before installing.
249: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 250: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 251: are installed properly, and start building libraries first libc
252: and libutil, install them and then continue building all the
1.241 wiz 253: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 254: the new libraries are installed, you can restart the build.
255: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 256: rebuild the required packages to update their shared libraries.
257: Any package you rebuild will require rebuilding all the packages
258: that depend on it.
1.186 christos 259: 5. Next time you run pwd_mkdb with the new binary, the file
260: will be upgraded and it will not be backwards compatible.
1.190 apb 261: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
262: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 263: for utmp. You are better off removing the old files after
1.190 apb 264: upgrading. The automated clearing of /var/run during
265: boot, and the automated rotating of files in /var/log by
266: newsyslog(8), may mean that you do not have to remove the
267: files manually.
268: 7. The optional accounting file (/var/account/acct, see
269: accton(8)) has not been versioned, and will need to be
270: removed. The automatic rotation of the accounting file by
271: /etc/daily limits the bad consequences of failure to remove
272: the file.
1.196 dholland 273: 8. Application software that writes time_t to binary files on
1.241 wiz 274: disk will break or need attention. Most notably: if you are
1.196 dholland 275: using PostgreSQL < 8.4, you need to dump your databases,
276: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 277:
1.183 pgoyette 278: 20081219:
279: config(1) has been updated, and one of the files it creates -
280: swapnetbsd.o - has changed format. You need to rebuild config
281: (done automatically by build.sh) and then you need to rerun
282: config on all kernel configuration files before rebuilding those
283: kernels.
284:
1.181 cube 285: 20081205:
286: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
287: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
288: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 289:
1.179 tsutsui 290: 20081122:
1.182 tsutsui 291: On i386, various kernel options(4) in GENERIC including
1.180 wiz 292: file systems have been disabled and moved into kernel modules.
293: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 294: following files as well as a new GENERIC kernel:
295:
296: - build and install kernel modules from src/sys/modules
297:
298: - install the latest bootloader, which will load a module
1.180 wiz 299: for the file system from which the kernel is loaded automatically
1.179 tsutsui 300:
1.180 wiz 301: If you have to load your kernel from a file system which is not of
302: the same type as the root file system, you have to load the necessary
303: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 304:
1.178 lukem 305: 20080827:
306: If you built and installed a libc from sources between
307: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
308: which results in false errors reported by lint(1).
309: Since this breaks the libc build itself, manual help is
1.180 wiz 310: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 311: $ (cd lib/libc && make MKLINT=no dependall install)
312:
1.177 christos 313: 20080813:
314: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 315: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 316:
1.200 dholland 317: 20080802:
318: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 319: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 320: for -current.
321:
322: Threaded programs (using libpthread) and C++ programs (using
323: libstdc++) compiled after 20070907 and before 20080802 need to
324: be recompiled.
325:
326: One way to find affected pkgsrc packages:
327:
328: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
329: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
330:
1.175 simonb 331: 20080731:
332: WAPBL (metadata journaling support) has been added, but at this
333: time isn't backwards compatible with pre-WAPBL aware kernels
334: and userland (fsck_ffs in particular). Please make sure you
335: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 336: especially an uncleanly mounted journaled filesystem. WAPBL
337: also requires the super block to be in the UFS2 format. You
338: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 339:
1.174 lukem 340: 20080721:
341: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
342: isn't defined.
343:
1.173 freza 344: 20080531:
1.241 wiz 345: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
346: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 347: utility needs to be rebuilt and reinstalled as older binaries
1.241 wiz 348: won't work correctly. The following sequence of commands:
1.173 freza 349:
350: $ (cd sys/sys/ && nbmake-$arch includes)
351: $ (cd sbin/drvctl/ && nbmake-$arch clean)
352: $ (cd sbin/drvctl/ && nbmake-$arch all)
353:
354: leaves new drvctl utility in sbin/drvctl build directory.
355:
1.172 lukem 356: 20080503:
357: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
358:
1.171 he 359: 20080521:
360: For a while, unprivileged UPDATE builds would fail to
361: succeed at the checkflist stage, complaining that
362: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
363: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
364: If you already hit this problem, update the .mk file,
365: remove ${DESTDIR}/stand/<arch>, and re-run the build.
366:
1.174 lukem 367: 20080303:
368: Linker warnings are now fatal if $WARNS>0.
369:
1.170 christos 370: 20080126:
371: The posix_fadvise system call has been changed from an assembly
1.241 wiz 372: stub, to a c file that calls an assembly stub. You need to
1.170 christos 373: 'rm -f posix_fadvise.* .depend' in the libc build directory to
374: avoid using the old assembly stub.
375:
1.168 joerg 376: 20071209:
1.241 wiz 377: The acpiec(4) driver has been split into two attachments. If you
1.168 joerg 378: get ACPI errors before the attachment, please update your kernel
1.169 wiz 379: configuration file appropriately or see GENERIC for more details.
1.168 joerg 380:
1.166 xtraeme 381: 20071115:
382: The it(4) driver has been renamed to itesio(4) and the old port
383: argument specified in the kernel configuration file is not valid
1.241 wiz 384: anymore. The itesio(4) driver now uses the Super I/O address port
385: rather than the EC address port. Please update your kernel
1.167 wiz 386: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 387:
1.165 jmmv 388: 20071028:
389: The pccons(4) driver has been removed from the NetBSD/shark port.
390: You need to update any custom kernel configuration file you have
391: to remove any references to pccons (which includes removing the
392: now useless XSERVER option) and replace them with the correct

1.164 gdt 396: 20070913:
397: A latent bug in dhclient/dhcpd that caused it to be unable to
398: enumerate interfaces was fixed. The bug began to cause
399: problems after 20070911 when the kernel's SIOCGIFCONF
400: implementation was repaired. From 20070529 to 20070911 racoon
401: could not enumerate interfaces. (These are noted because
402: normal kernel/userspace version matching hygiene is not
403: sufficient to avoid this problem.) Ensure that both kernel
404: and userland are from after 20070913.

1.241 wiz 407: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It

1.161 dsl 412: 20070422:
413: The way OS emulations lookup filenames inside the emulation root
414: has been changed. Rather than modify the pathname (and copy back
415: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 416: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 417: root file system will be relative to that file system - unless they
1.161 dsl 418: start /../ this is useful when the emulated root is a real install

444: The threading model was changed when the newlock2 branch
445: was merged to NetBSD-current. If you boot with a new
446: kernel (version 4.99.10), then you also need a new pthread
447: library (/usr/lib/libpthread.so.0.7). If you boot with
448: an old kernel, then you need the old pthread library
449: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
450: the pthread library in sync, old threaded applications should
451: continue to work with an old or new kernel. Note that named(8)

490: errors will result.

1.1 abs 492: Hints for a more successful build:
493: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 494: Use build.sh, but do not use its "expert mode":
1.132 jmmv 495: This will automatically build the tools in the
1.123 jmc 496: correct order, and it will keep the tools and the
497: new build products from interfering with the running
498: system. This will allow you to ignore most of the
499: other advice in this file.
1.2 mrg 500: Build a new kernel first:
501: This makes sure that any new system calls or features
502: expected by the new userland will be present. This
503: helps to avoid critical errors when upgrading.
1.1 abs 504: Use object directories:
505: This helps to keep stale object
506: files from polluting the build if a Makefile "forgets"
507: about one. It also makes it easier to clean up after
508: a build. It's also necessary if you want to use the
509: same source tree for multiple machines.
1.123 jmc 510: To use object directories with build.sh:
511: a) invoke build.sh with the "-M" or "-O" options.
512: To use object directories without using build.sh:
1.1 abs 513: a) cd /usr/src ; make cleandir
1.2 mrg 514: b) Add "OBJMACHINE=yes" to /etc/mk.conf
515: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 516: d) cd /usr/src ; make build
1.2 mrg 517: Note that running "make obj" in a directory will create
518: in obj.$MACHINE directory.
1.1 abs 519: Build to a DESTDIR:
1.123 jmc 520: This helps to keep old installed files (especially libraries)
521: from interfering with the new build.
522: To build to a DESTDIR with build.sh, use the "-D" option.
523: To build to a DESTDIR without using build.sh, set the DESTDIR
524: environment variable before running make build. It should be
525: set to the pathname of an initially empty directory.
526: Problems: if you do not use build.sh, you might need to
527: update critical utilities without using DESTDIR since
528: nothing is executed from what is installed in DESTDIR.
529: (See critical utils, below.)
1.1 abs 530: Build often:
531: This keeps critical utilities current enough to not choke
532: on any other part of the source tree that depends on up to
1.123 jmc 533: date functionality. If you use build.sh, you should not have
534: this problem.
1.241 wiz 535:
1.1 abs 536: What to do if things don't work:
537: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 538: When things don't work there are usually a few things that commonly
1.1 abs 539: should be done.
540: 1) make includes
541: This should be done automatically by make build.
542: 2) cd share/mk && make install
543: Again, automatically done by make build.
544:
545: Failsafe rebuild of a small part of the tree:
546: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
547: To make sure you rebuild something correctly you want to do
548: something like the following:
549: 1) Make sure the includes and .mk files are up to date.
550: 2) Make sure any program used to build the particular
551: utility is up to date. (yacc, lex, etc...)
552: 3) cd ...path/to/util...
553: make cleandir
554: rm ...all obj directories...
555: make cleandir # yes, again
556: make obj
557: make depend && make
558:
559: Failsafe rebuild of the entire tree:
560: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
561: If you really want to make sure the source tree is clean and
1.2 mrg 562: ready for a build try the following. Note that sourcing /etc/mk.conf
563: (a make(1) Makefile) in this manner is not right, and will not work
