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.

17: ^^^^^^^^^^^^^^^
1.230 tls 18:
1.245 ! mrg 19: 20130531:
! 20: The xdm update may cause build failure due to xdm.man being
! 21: in the obj tree. Make sure to ensure any like this:
! 22: nbmake: nbmake: don't know how to make xdm.man. Stop
! 23: is fixed by deleting the xdm.man in the obj tree.
! 24:
1.244 mrg 25: 20130530:
26: Updates of many xsrc packages will leave old .pc files around.
27: Best to clean out the xsrc objdir entirely before rebuilds.
28:
1.242 christos 29: 20130301:
30: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 31: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 32:
1.238 dholland 33: 20120726:
1.241 wiz 34: The update of OpenSSL requires cleaning both the OpenSSL build
35: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 36: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 37: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 38: cause third-party software to link incorrectly and/or crash.
1.238 dholland 39:
1.237 wiz 40: 20120507:
1.241 wiz 41: The database schema for makemandb was changed. You will
1.237 wiz 42: need to update the database using 'makemandb -f' or wait
43: for the next weekly run to fix it.
44:
1.236 bsh 45: 20120319:
46: sys/conf/Makefile.kern.inc has been modified to adjust the
47: size of db_symtab automatically. You need to update dbsym in
48: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
49: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
50: mk.conf.
51:
1.235 joerg 52: 20120216:
1.241 wiz 53: Default for MKCATPAGES changed to NO. Update builds will fail
54: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 55: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 56: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 57: the next run of weekly will fix it.
1.233 joerg 58:
1.232 christos 59: 20111227:
60: If you built between 20111225 and 20111227 you need to remove
61: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
62: bump has been reverted.
63:
1.231 tls 64: 20111125:
65: The "rnd" pseudodevice has been added to sys/conf/std, which
66: means it should no longer be explicitly listed in kernel
67: configuration files. The line "pseudo-device rnd" should be
68: removed from any custom kernel config files users may have.
69:
1.230 tls 70: 20111119:
71: A problem with the datastructures used by the rndctl(8)
72: utility (pointers in datastructures in an array, making 32->64
73: bit compatibility very painful) has been fixed in a
74: non-backwards-compatible way. If you replace your kernel,
75: replace your rndctl executable too.
1.241 wiz 76:
1.229 jym 77: 20111001:
78: the prop_*_send_syscall() functions from proplib(3) have been
79: changed and their new version is not backward compatible with the old
1.241 wiz 80: one. So ensure that all consumers of these functions (currently:
1.229 jym 81: quota2 code and its tests) are updated together with the new lib.
82:
1.228 mrg 83: 20110817:
84: sparc has been changed to use GCC 4.5.3, so any objdir or
85: DESTDIR for them should be deleted before updating.
86:
1.227 riastrad 87: 20110806:
88: i386 and amd64 have been changed to use GCC 4.5.3, so any
89: objdir or DESTDIR for them should be deleted before updating.
90:
1.226 mrg 91: 20110805:
92: The update to GCC 4.5.3 requires a non-trivial portion of
93: the tree to be cleaned. Best to delete both objdir and
94: DESTDIR before running this update. So far, only the
95: sparc64, mips and powerpc platforms have changed.
96:
1.225 matt 97: 20110803:
1.241 wiz 98: The layout of external/public-domain/xz has changed. To do an
1.225 matt 99: update build you will have to remove the contents of the OBJDIR
100: for external/public-domain/xz/bin by hand as the xz entry there
101: is now a directory.
102:
1.223 joerg 103: 20110410:
1.241 wiz 104: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 105: update build you have to clean both tools/binutils and
106: tools/gcc by hand.
1.223 joerg 107:
1.222 plunky 108: 20110328:
109: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 110: ordering issues with "make all". It may be necessary to remove
1.222 plunky 111: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
112: if your update build fails, as the "Xorg" entry there is now a
113: directory.
114:
1.220 joerg 115: 20110121:
1.221 lukem 116: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 117: the build of individual parts of the tree. This is handled
118: correctly by build.sh. Manual builds have to update /usr/share/mk
119: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 120:
1.217 jruoho 121: 20101217:
122: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 123: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 124: group(5) in order to make the program work with existing setups.
125:
1.216 christos 126: 20101125:
127: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 128: variables with names that contain '='. Revision 1.18 of env.c
129: assumed that this was allowed. Installing a new libc with an
1.216 christos 130: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
131: break which affects the autoconf tests for dependency finding,
132: so building gcc will end up printing:
133: checking dependency style of gcc... none
134: configure: error: no usable dependency style found
135: Fix it by rebuilding and re-installing env.
1.138 lukem 136:
1.215 mrg 137: 20101119:
138: Recent Xorg updates in xsrc/external/mit/ may cause various build
139: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
140: have any build problems with xsrc, or problems with mismatched
141: versions between xorg-server and drivers.
142:
1.213 jmmv 143: 20100604:
144: The update of ATF to 0.9 causes old tests written in shell to fail
145: unless they are rebuilt. If you are building with MKUPDATE=yes,
146: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
147: trees by hand.
148:
1.211 tnozaki 149: 20100522:
1.212 mrg 150: Recent Xorg updates in xsrc/external/mit/ will cause various build
151: problems. Delete your entire DESTDIR and OBJDIR if you have any
152: build problems with xsrc.
153:
154: 20100522:
1.211 tnozaki 155: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 156: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 157:
1.210 christos 158: 20100520:
1.241 wiz 159: The location of the xkb compiled descriptions has changed. Please
1.210 christos 160: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
161:
1.209 njoly 162: 20100222:
163: The shared objects file extension has been changed from .so to
164: .pico, in order to avoid conflicts with shared libraries names
165: libXX.so. All now stale regular .so files can be removed from
166: your object directories.
167:
1.208 roy 168: 20100204:
169: The termcap database has been removed from the sources,
170: but has not been marked obsolete so it is not removed
171: from the system when upgrading.
172: As such, you will need to remove them from your object
173: and destination directories.
174:
1.203 dyoung 175: 20091101:
1.205 dholland 176: After updating, it may be necessary to make the 'cleandir'
177: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
178: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
179: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 180:
1.202 mrg 181: 20091001:
1.206 dholland 182: On amd64 you must rebuild tools (to get the new binutils)
183: before building a kernel, or the build fails on cpufunc.S.
184:
185: 20091001:
1.202 mrg 186: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
187: symlink, failing the build. Delete the link, and the subdir
188: it is in, and retry your build.
189:
1.201 dsl 190: 20090718:
191: libc build changed so that strchr() provides the extra entry
1.241 wiz 192: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 193: may fail because the archive contains the unwanted index.o.
194: (Similarly for strrchr() and rindex().)
195:
1.198 mrg 196: 20090709:
197: Native Xorg was upgraded again. Builds will probably fail again
198: without a clean objdir, at least for src/external/mit/xorg.
199:
1.197 mrg 200: 20090616:
201: Native Xorg was upgraded. Builds will need a clean objdir for
202: src/external/mit/xorg. Upgrading a system from sets will not
203: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
204: subdirectory has been changed into a file, and this needs to
205: be manually "rm -r"'ed before installing xbase.tgz.
206:
1.195 perry 207: 20090501:
208: Several new functions were added to string.h/libc, and this
209: can cause autoconf problems during the tool build for people
1.241 wiz 210: who fail to clean out their tools objects properly. If you
1.195 perry 211: note messages about stpcpy, stpncpy or strnlen accompanying a
212: failure during the tool build, clean out all your tools
213: objects and start again.
214:
1.194 mrg 215: 20090325:
216: The i386 port was switched to i486 default toolchain. This requires
217: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
218:
1.192 skrll 219: 20090126:
1.241 wiz 220: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 221: need to 'rm -f __posix_fadvise50.*' in the libc build directory
222: to avoid using the old assembly stub.
1.192 skrll 223:
1.191 joerg 224: 20090202:
225: pkg_install now depends on the pkgdb cache for automatic conflict
226: detection. It is recommented to rebuild the cache with
227: ``pkg_admin rebuild''.
228:
1.184 christos 229: 20090110:
1.241 wiz 230: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
231: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 232: This is needed even in the MODULAR kernel because there is
233: conditionally compiled code in rtsock.c.
1.184 christos 234: 2. make sure build.sh completes and the binaries in a chroot work
235: before installing.
236: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 237: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 238: are installed properly, and start building libraries first libc
239: and libutil, install them and then continue building all the
1.241 wiz 240: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 241: the new libraries are installed, you can restart the build.
242: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 243: rebuild the required packages to update their shared libraries.
244: Any package you rebuild will require rebuilding all the packages
245: that depend on it.
1.186 christos 246: 5. Next time you run pwd_mkdb with the new binary, the file
247: will be upgraded and it will not be backwards compatible.
1.190 apb 248: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
249: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 250: for utmp. You are better off removing the old files after
1.190 apb 251: upgrading. The automated clearing of /var/run during
252: boot, and the automated rotating of files in /var/log by
253: newsyslog(8), may mean that you do not have to remove the
254: files manually.
255: 7. The optional accounting file (/var/account/acct, see
256: accton(8)) has not been versioned, and will need to be
257: removed. The automatic rotation of the accounting file by
258: /etc/daily limits the bad consequences of failure to remove
259: the file.
1.196 dholland 260: 8. Application software that writes time_t to binary files on
1.241 wiz 261: disk will break or need attention. Most notably: if you are
1.196 dholland 262: using PostgreSQL < 8.4, you need to dump your databases,
263: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 264:
1.183 pgoyette 265: 20081219:
266: config(1) has been updated, and one of the files it creates -
267: swapnetbsd.o - has changed format. You need to rebuild config
268: (done automatically by build.sh) and then you need to rerun
269: config on all kernel configuration files before rebuilding those
270: kernels.
271:
1.181 cube 272: 20081205:
273: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
274: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
275: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 276:
1.179 tsutsui 277: 20081122:
1.182 tsutsui 278: On i386, various kernel options(4) in GENERIC including
1.180 wiz 279: file systems have been disabled and moved into kernel modules.
280: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 281: following files as well as a new GENERIC kernel:
282:
283: - build and install kernel modules from src/sys/modules
284:
285: - install the latest bootloader, which will load a module
1.180 wiz 286: for the file system from which the kernel is loaded automatically
1.179 tsutsui 287:
1.180 wiz 288: If you have to load your kernel from a file system which is not of
289: the same type as the root file system, you have to load the necessary
290: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 291:
1.178 lukem 292: 20080827:
293: If you built and installed a libc from sources between
294: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
295: which results in false errors reported by lint(1).
296: Since this breaks the libc build itself, manual help is
1.180 wiz 297: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 298: $ (cd lib/libc && make MKLINT=no dependall install)
299:
1.177 christos 300: 20080813:
301: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 302: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 303:
1.200 dholland 304: 20080802:
305: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 306: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 307: for -current.
308:
309: Threaded programs (using libpthread) and C++ programs (using
310: libstdc++) compiled after 20070907 and before 20080802 need to
311: be recompiled.
312:
313: One way to find affected pkgsrc packages:
314:
315: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
316: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
317:
1.175 simonb 318: 20080731:
319: WAPBL (metadata journaling support) has been added, but at this
320: time isn't backwards compatible with pre-WAPBL aware kernels
321: and userland (fsck_ffs in particular). Please make sure you
322: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 323: especially an uncleanly mounted journaled filesystem. WAPBL
324: also requires the super block to be in the UFS2 format. You
325: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 326:
1.174 lukem 327: 20080721:
328: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
329: isn't defined.
330:
1.173 freza 331: 20080531:
1.241 wiz 332: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
333: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 334: utility needs to be rebuilt and reinstalled as older binaries
1.241 wiz 335: won't work correctly. The following sequence of commands:
1.173 freza 336:
337: $ (cd sys/sys/ && nbmake-$arch includes)
338: $ (cd sbin/drvctl/ && nbmake-$arch clean)
339: $ (cd sbin/drvctl/ && nbmake-$arch all)
340:
341: leaves new drvctl utility in sbin/drvctl build directory.
342:
1.172 lukem 343: 20080503:
344: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
345:
1.171 he 346: 20080521:
347: For a while, unprivileged UPDATE builds would fail to
348: succeed at the checkflist stage, complaining that
349: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
350: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
351: If you already hit this problem, update the .mk file,
352: remove ${DESTDIR}/stand/<arch>, and re-run the build.
353:
1.174 lukem 354: 20080303:
355: Linker warnings are now fatal if $WARNS>0.
356:
1.170 christos 357: 20080126:
358: The posix_fadvise system call has been changed from an assembly
1.241 wiz 359: stub, to a c file that calls an assembly stub. You need to
1.170 christos 360: 'rm -f posix_fadvise.* .depend' in the libc build directory to
361: avoid using the old assembly stub.
362:
1.168 joerg 363: 20071209:
1.241 wiz 364: The acpiec(4) driver has been split into two attachments. If you
1.168 joerg 365: get ACPI errors before the attachment, please update your kernel
1.169 wiz 366: configuration file appropriately or see GENERIC for more details.
1.168 joerg 367:
1.166 xtraeme 368: 20071115:
369: The it(4) driver has been renamed to itesio(4) and the old port
370: argument specified in the kernel configuration file is not valid
1.241 wiz 371: anymore. The itesio(4) driver now uses the Super I/O address port
372: rather than the EC address port. Please update your kernel
1.167 wiz 373: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 374:
1.165 jmmv 375: 20071028:
376: The pccons(4) driver has been removed from the NetBSD/shark port.
377: You need to update any custom kernel configuration file you have
378: to remove any references to pccons (which includes removing the
379: now useless XSERVER option) and replace them with the correct
380: entries for the wscons driver. See the GENERIC configuration file
381: for more details.
382:
1.164 gdt 383: 20070913:
384: A latent bug in dhclient/dhcpd that caused it to be unable to
385: enumerate interfaces was fixed. The bug began to cause
386: problems after 20070911 when the kernel's SIOCGIFCONF
387: implementation was repaired. From 20070529 to 20070911 racoon
388: could not enumerate interfaces. (These are noted because
389: normal kernel/userspace version matching hygiene is not
390: sufficient to avoid this problem.) Ensure that both kernel
391: and userland are from after 20070913.

1.161 dsl 399: 20070422:
400: The way OS emulations lookup filenames inside the emulation root
401: has been changed. Rather than modify the pathname (and copy back
402: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 403: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 404: root file system will be relative to that file system - unless they
1.161 dsl 405: start /../ this is useful when the emulated root is a real install
406: that has such links.

431: The threading model was changed when the newlock2 branch
432: was merged to NetBSD-current. If you boot with a new
433: kernel (version 4.99.10), then you also need a new pthread
434: library (/usr/lib/libpthread.so.0.7). If you boot with
435: an old kernel, then you need the old pthread library
436: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
437: the pthread library in sync, old threaded applications should
438: continue to work with an old or new kernel. Note that named(8)
439: is the only threaded application in the base system.

454: changed to indicate that our libc has ssp support built-in and
1.241 wiz 455: does not depend on -lssp and -lssp-nonshared. You'll need to

463: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
464: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC

477: errors will result.

1.1 abs 479: Hints for a more successful build:
480: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 481: Use build.sh, but do not use its "expert mode":
1.132 jmmv 482: This will automatically build the tools in the
1.123 jmc 483: correct order, and it will keep the tools and the
484: new build products from interfering with the running
485: system. This will allow you to ignore most of the
486: other advice in this file.
1.2 mrg 487: Build a new kernel first:
488: This makes sure that any new system calls or features
489: expected by the new userland will be present. This
490: helps to avoid critical errors when upgrading.
1.1 abs 491: Use object directories:
492: This helps to keep stale object
493: files from polluting the build if a Makefile "forgets"
494: about one. It also makes it easier to clean up after
495: a build. It's also necessary if you want to use the
496: same source tree for multiple machines.
1.123 jmc 497: To use object directories with build.sh:
498: a) invoke build.sh with the "-M" or "-O" options.
499: To use object directories without using build.sh:
1.1 abs 500: a) cd /usr/src ; make cleandir
1.2 mrg 501: b) Add "OBJMACHINE=yes" to /etc/mk.conf
502: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 503: d) cd /usr/src ; make build
1.2 mrg 504: Note that running "make obj" in a directory will create
505: in obj.$MACHINE directory.
1.1 abs 506: Build to a DESTDIR:
1.123 jmc 507: This helps to keep old installed files (especially libraries)
508: from interfering with the new build.
509: To build to a DESTDIR with build.sh, use the "-D" option.
510: To build to a DESTDIR without using build.sh, set the DESTDIR
511: environment variable before running make build. It should be
512: set to the pathname of an initially empty directory.
513: Problems: if you do not use build.sh, you might need to
514: update critical utilities without using DESTDIR since
515: nothing is executed from what is installed in DESTDIR.
516: (See critical utils, below.)
1.1 abs 517: Build often:
518: This keeps critical utilities current enough to not choke
519: on any other part of the source tree that depends on up to
1.123 jmc 520: date functionality. If you use build.sh, you should not have
521: this problem.
1.241 wiz 522:
1.1 abs 523: What to do if things don't work:
524: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 525: When things don't work there are usually a few things that commonly
1.1 abs 526: should be done.
527: 1) make includes
528: This should be done automatically by make build.
529: 2) cd share/mk && make install
530: Again, automatically done by make build.
531:
532: Failsafe rebuild of a small part of the tree:
533: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
534: To make sure you rebuild something correctly you want to do
535: something like the following:
536: 1) Make sure the includes and .mk files are up to date.
537: 2) Make sure any program used to build the particular
538: utility is up to date. (yacc, lex, etc...)
539: 3) cd ...path/to/util...
540: make cleandir
541: rm ...all obj directories...
542: make cleandir # yes, again
543: make obj
544: make depend && make
545:
546: Failsafe rebuild of the entire tree:
547: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
548: If you really want to make sure the source tree is clean and
1.2 mrg 549: ready for a build try the following. Note that sourcing /etc/mk.conf
550: (a make(1) Makefile) in this manner is not right, and will not work
551: for anyone who uses any make(1) features in /etc/mk.conf.
