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: ^^^^^^^^^^^^^^^
1.229.2.1 yamt 18:
1.229.2.3! yamt 19: 20120726:
! 20: The update of OpenSSL requires cleaning both the OpenSSL build
! 21: directory and DESTDIR. *Even non-update builds require cleaning
! 22: DESTDIR.* Builds done without taking these steps may fail, or in
! 23: some cases may succeed and install broken OpenSSL libraries that
! 24: cause third-party software to link incorrectly and/or crash.
! 25:
1.229.2.2 yamt 26: 20120507:
1.229.2.3! yamt 27: The database schema for makemandb was changed. You will
1.229.2.2 yamt 28: need to update the database using 'makemandb -f' or wait
29: for the next weekly run to fix it.
30:
1.229.2.1 yamt 31: 20120319:
32: sys/conf/Makefile.kern.inc has been modified to adjust the
33: size of db_symtab automatically. You need to update dbsym in
34: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
35: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
36: mk.conf.
37:
38: 20120216:
1.229.2.3! yamt 39: Default for MKCATPAGES changed to NO. Update builds will fail
! 40: unless DESTDIR is cleaned manually. If you built between 20120207
! 41: and 20120216, daily and weekly could have created an unreadable
! 42: /var/db/man.db index for apropos. Running makemandb -f or
1.229.2.1 yamt 43: the next run of weekly will fix it.
44:
45: 20111227:
46: If you built between 20111225 and 20111227 you need to remove
47: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
48: bump has been reverted.
49:
50: 20111125:
51: The "rnd" pseudodevice has been added to sys/conf/std, which
52: means it should no longer be explicitly listed in kernel
53: configuration files. The line "pseudo-device rnd" should be
54: removed from any custom kernel config files users may have.
55:
56: 20111119:
57: A problem with the datastructures used by the rndctl(8)
58: utility (pointers in datastructures in an array, making 32->64
59: bit compatibility very painful) has been fixed in a
60: non-backwards-compatible way. If you replace your kernel,
61: replace your rndctl executable too.
1.229.2.3! yamt 62:
1.229 jym 63: 20111001:
64: the prop_*_send_syscall() functions from proplib(3) have been
65: changed and their new version is not backward compatible with the old
1.229.2.3! yamt 66: one. So ensure that all consumers of these functions (currently:
1.229 jym 67: quota2 code and its tests) are updated together with the new lib.
68:
1.228 mrg 69: 20110817:
70: sparc has been changed to use GCC 4.5.3, so any objdir or
71: DESTDIR for them should be deleted before updating.
72:
1.227 riastrad 73: 20110806:
74: i386 and amd64 have been changed to use GCC 4.5.3, so any
75: objdir or DESTDIR for them should be deleted before updating.
76:
1.226 mrg 77: 20110805:
78: The update to GCC 4.5.3 requires a non-trivial portion of
79: the tree to be cleaned. Best to delete both objdir and
80: DESTDIR before running this update. So far, only the
81: sparc64, mips and powerpc platforms have changed.
82:
1.225 matt 83: 20110803:
1.229.2.3! yamt 84: The layout of external/public-domain/xz has changed. To do an
1.225 matt 85: update build you will have to remove the contents of the OBJDIR
86: for external/public-domain/xz/bin by hand as the xz entry there
87: is now a directory.
88:
1.223 joerg 89: 20110410:
1.229.2.3! yamt 90: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 91: update build you have to clean both tools/binutils and
92: tools/gcc by hand.
1.223 joerg 93:
1.222 plunky 94: 20110328:
95: Building the Xorg binary was moved into a subdirectory to fix
1.229.2.3! yamt 96: ordering issues with "make all". It may be necessary to remove
1.222 plunky 97: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
98: if your update build fails, as the "Xorg" entry there is now a
99: directory.
100:
1.220 joerg 101: 20110121:
1.221 lukem 102: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 103: the build of individual parts of the tree. This is handled
104: correctly by build.sh. Manual builds have to update /usr/share/mk
105: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 106:
1.217 jruoho 107: 20101217:
108: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.229.2.3! yamt 109: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 110: group(5) in order to make the program work with existing setups.
111:
1.216 christos 112: 20101125:
113: The latest changes to setenv(3) dissallow setting environment
1.229.2.3! yamt 114: variables with names that contain '='. Revision 1.18 of env.c
! 115: assumed that this was allowed. Installing a new libc with an
1.216 christos 116: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
117: break which affects the autoconf tests for dependency finding,
118: so building gcc will end up printing:
119: checking dependency style of gcc... none
120: configure: error: no usable dependency style found
121: Fix it by rebuilding and re-installing env.
1.138 lukem 122:
1.215 mrg 123: 20101119:
124: Recent Xorg updates in xsrc/external/mit/ may cause various build
125: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
126: have any build problems with xsrc, or problems with mismatched
127: versions between xorg-server and drivers.
128:
1.213 jmmv 129: 20100604:
130: The update of ATF to 0.9 causes old tests written in shell to fail
131: unless they are rebuilt. If you are building with MKUPDATE=yes,
132: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
133: trees by hand.
134:
1.211 tnozaki 135: 20100522:
1.212 mrg 136: Recent Xorg updates in xsrc/external/mit/ will cause various build
137: problems. Delete your entire DESTDIR and OBJDIR if you have any
138: build problems with xsrc.
139:
140: 20100522:
1.211 tnozaki 141: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 142: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 143:
1.210 christos 144: 20100520:
1.229.2.3! yamt 145: The location of the xkb compiled descriptions has changed. Please
1.210 christos 146: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
147:
1.209 njoly 148: 20100222:
149: The shared objects file extension has been changed from .so to
150: .pico, in order to avoid conflicts with shared libraries names
151: libXX.so. All now stale regular .so files can be removed from
152: your object directories.
153:
1.208 roy 154: 20100204:
155: The termcap database has been removed from the sources,
156: but has not been marked obsolete so it is not removed
157: from the system when upgrading.
158: As such, you will need to remove them from your object
159: and destination directories.
160:
1.203 dyoung 161: 20091101:
1.205 dholland 162: After updating, it may be necessary to make the 'cleandir'
163: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
164: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
165: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 166:
1.202 mrg 167: 20091001:
1.206 dholland 168: On amd64 you must rebuild tools (to get the new binutils)
169: before building a kernel, or the build fails on cpufunc.S.
170:
171: 20091001:
1.202 mrg 172: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
173: symlink, failing the build. Delete the link, and the subdir
174: it is in, and retry your build.
175:
1.201 dsl 176: 20090718:
177: libc build changed so that strchr() provides the extra entry
1.229.2.3! yamt 178: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 179: may fail because the archive contains the unwanted index.o.
180: (Similarly for strrchr() and rindex().)
181:
1.198 mrg 182: 20090709:
183: Native Xorg was upgraded again. Builds will probably fail again
184: without a clean objdir, at least for src/external/mit/xorg.
185:
1.197 mrg 186: 20090616:
187: Native Xorg was upgraded. Builds will need a clean objdir for
188: src/external/mit/xorg. Upgrading a system from sets will not
189: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
190: subdirectory has been changed into a file, and this needs to
191: be manually "rm -r"'ed before installing xbase.tgz.
192:
1.195 perry 193: 20090501:
194: Several new functions were added to string.h/libc, and this
195: can cause autoconf problems during the tool build for people
1.229.2.3! yamt 196: who fail to clean out their tools objects properly. If you
1.195 perry 197: note messages about stpcpy, stpncpy or strnlen accompanying a
198: failure during the tool build, clean out all your tools
199: objects and start again.
200:
1.194 mrg 201: 20090325:
202: The i386 port was switched to i486 default toolchain. This requires
203: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
204:
1.192 skrll 205: 20090126:
1.229.2.3! yamt 206: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 207: need to 'rm -f __posix_fadvise50.*' in the libc build directory
208: to avoid using the old assembly stub.
1.192 skrll 209:
1.191 joerg 210: 20090202:
211: pkg_install now depends on the pkgdb cache for automatic conflict
212: detection. It is recommented to rebuild the cache with
213: ``pkg_admin rebuild''.
214:
1.184 christos 215: 20090110:
1.229.2.3! yamt 216: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
! 217: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 218: This is needed even in the MODULAR kernel because there is
219: conditionally compiled code in rtsock.c.
1.184 christos 220: 2. make sure build.sh completes and the binaries in a chroot work
221: before installing.
222: 3. If you don't use build.sh and you build directly to root, and
1.229.2.3! yamt 223: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 224: are installed properly, and start building libraries first libc
225: and libutil, install them and then continue building all the
1.229.2.3! yamt 226: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 227: the new libraries are installed, you can restart the build.
228: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 229: rebuild the required packages to update their shared libraries.
230: Any package you rebuild will require rebuilding all the packages
231: that depend on it.
1.186 christos 232: 5. Next time you run pwd_mkdb with the new binary, the file
233: will be upgraded and it will not be backwards compatible.
1.190 apb 234: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
235: lastlogx(5)) have been versioned, and there is a heuristic
1.229.2.3! yamt 236: for utmp. You are better off removing the old files after
1.190 apb 237: upgrading. The automated clearing of /var/run during
238: boot, and the automated rotating of files in /var/log by
239: newsyslog(8), may mean that you do not have to remove the
240: files manually.
241: 7. The optional accounting file (/var/account/acct, see
242: accton(8)) has not been versioned, and will need to be
243: removed. The automatic rotation of the accounting file by
244: /etc/daily limits the bad consequences of failure to remove
245: the file.
1.196 dholland 246: 8. Application software that writes time_t to binary files on
1.229.2.3! yamt 247: disk will break or need attention. Most notably: if you are
1.196 dholland 248: using PostgreSQL < 8.4, you need to dump your databases,
249: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 250:
1.183 pgoyette 251: 20081219:
252: config(1) has been updated, and one of the files it creates -
253: swapnetbsd.o - has changed format. You need to rebuild config
254: (done automatically by build.sh) and then you need to rerun
255: config on all kernel configuration files before rebuilding those
256: kernels.
257:
1.181 cube 258: 20081205:
259: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
260: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
261: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 262:
1.179 tsutsui 263: 20081122:
1.182 tsutsui 264: On i386, various kernel options(4) in GENERIC including
1.180 wiz 265: file systems have been disabled and moved into kernel modules.
266: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 267: following files as well as a new GENERIC kernel:
268:
269: - build and install kernel modules from src/sys/modules
270:
271: - install the latest bootloader, which will load a module
1.180 wiz 272: for the file system from which the kernel is loaded automatically
1.179 tsutsui 273:
1.180 wiz 274: If you have to load your kernel from a file system which is not of
275: the same type as the root file system, you have to load the necessary
276: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 277:
1.178 lukem 278: 20080827:
279: If you built and installed a libc from sources between
280: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
281: which results in false errors reported by lint(1).
282: Since this breaks the libc build itself, manual help is
1.180 wiz 283: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 284: $ (cd lib/libc && make MKLINT=no dependall install)
285:
1.177 christos 286: 20080813:
287: MKDEBUG build was broken because the .depend files did not know
1.229.2.3! yamt 288: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 289:
1.200 dholland 290: 20080802:
291: A regression in binary compatibility for pthread_mutex_t has
1.229.2.3! yamt 292: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 293: for -current.
294:
295: Threaded programs (using libpthread) and C++ programs (using
296: libstdc++) compiled after 20070907 and before 20080802 need to
297: be recompiled.
298:
299: One way to find affected pkgsrc packages:
300:
301: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
302: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
303:
1.175 simonb 304: 20080731:
305: WAPBL (metadata journaling support) has been added, but at this
306: time isn't backwards compatible with pre-WAPBL aware kernels
307: and userland (fsck_ffs in particular). Please make sure you
308: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 309: especially an uncleanly mounted journaled filesystem. WAPBL
310: also requires the super block to be in the UFS2 format. You
311: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 312:
1.174 lukem 313: 20080721:
314: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
315: isn't defined.
316:
1.173 freza 317: 20080531:
1.229.2.3! yamt 318: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
! 319: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 320: utility needs to be rebuilt and reinstalled as older binaries
1.229.2.3! yamt 321: won't work correctly. The following sequence of commands:
1.173 freza 322:
323: $ (cd sys/sys/ && nbmake-$arch includes)
324: $ (cd sbin/drvctl/ && nbmake-$arch clean)
325: $ (cd sbin/drvctl/ && nbmake-$arch all)
326:
327: leaves new drvctl utility in sbin/drvctl build directory.
328:
1.172 lukem 329: 20080503:
330: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
331:
1.171 he 332: 20080521:
333: For a while, unprivileged UPDATE builds would fail to
334: succeed at the checkflist stage, complaining that
335: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
336: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
337: If you already hit this problem, update the .mk file,
338: remove ${DESTDIR}/stand/<arch>, and re-run the build.
339:
1.174 lukem 340: 20080303:
341: Linker warnings are now fatal if $WARNS>0.
342:
1.170 christos 343: 20080126:
344: The posix_fadvise system call has been changed from an assembly
1.229.2.3! yamt 345: stub, to a c file that calls an assembly stub. You need to
1.170 christos 346: 'rm -f posix_fadvise.* .depend' in the libc build directory to
347: avoid using the old assembly stub.
348:
1.168 joerg 349: 20071209:
1.229.2.3! yamt 350: The acpiec(4) driver has been split into two attachments. If you
1.168 joerg 351: get ACPI errors before the attachment, please update your kernel
1.169 wiz 352: configuration file appropriately or see GENERIC for more details.
1.168 joerg 353:
1.166 xtraeme 354: 20071115:
355: The it(4) driver has been renamed to itesio(4) and the old port
356: argument specified in the kernel configuration file is not valid
1.229.2.3! yamt 357: anymore. The itesio(4) driver now uses the Super I/O address port
! 358: rather than the EC address port. Please update your kernel
1.167 wiz 359: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 360:
1.165 jmmv 361: 20071028:
362: The pccons(4) driver has been removed from the NetBSD/shark port.
363: You need to update any custom kernel configuration file you have
364: to remove any references to pccons (which includes removing the
365: now useless XSERVER option) and replace them with the correct
366: entries for the wscons driver. See the GENERIC configuration file
367: for more details.
368:
1.164 gdt 369: 20070913:
370: A latent bug in dhclient/dhcpd that caused it to be unable to
371: enumerate interfaces was fixed. The bug began to cause
372: problems after 20070911 when the kernel's SIOCGIFCONF
373: implementation was repaired. From 20070529 to 20070911 racoon
374: could not enumerate interfaces. (These are noted because
375: normal kernel/userspace version matching hygiene is not
376: sufficient to avoid this problem.) Ensure that both kernel
377: and userland are from after 20070913.
378:
1.163 joerg 379: 20070703:
1.229.2.3! yamt 380: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
1.199 dholland 381: calls the target-specific strip program, and the logic to pass
382: down STRIP from make has been removed. This requires a
383: re-installation of tools.
1.163 joerg 384:
1.161 dsl 385: 20070422:
386: The way OS emulations lookup filenames inside the emulation root
387: has been changed. Rather than modify the pathname (and copy back
388: to userspace) namei() and lookup() directly check the emulation
1.229.2.3! yamt 389: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 390: root file system will be relative to that file system - unless they
1.161 dsl 391: start /../ this is useful when the emulated root is a real install

404: updated and built after about 20070315, do "nbmake-$arch
405: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a

417: The threading model was changed when the newlock2 branch
418: was merged to NetBSD-current. If you boot with a new
419: kernel (version 4.99.10), then you also need a new pthread
420: library (/usr/lib/libpthread.so.0.7). If you boot with
421: an old kernel, then you need the old pthread library
422: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
423: the pthread library in sync, old threaded applications should
424: continue to work with an old or new kernel. Note that named(8)
425: is the only threaded application in the base system.

440: changed to indicate that our libc has ssp support built-in and
1.229.2.3! yamt 441: does not depend on -lssp and -lssp-nonshared. You'll need to
1.152 christos 442: make clean in src/tools/gcc first to rebuild the compiler.

1.151 rpaulo 447:
1.150 bjh21 448: 20060814:
449: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
450: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
451: kernel configuration for an example. X servers from the last

460: socket(2) has changed, and its system call has been versioned.

463: errors will result.

1.1 abs 465: Hints for a more successful build:
466: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 467: Use build.sh, but do not use its "expert mode":
1.132 jmmv 468: This will automatically build the tools in the
1.123 jmc 469: correct order, and it will keep the tools and the
470: new build products from interfering with the running
471: system. This will allow you to ignore most of the
472: other advice in this file.
1.2 mrg 473: Build a new kernel first:
474: This makes sure that any new system calls or features
475: expected by the new userland will be present. This
476: helps to avoid critical errors when upgrading.
1.1 abs 477: Use object directories:
478: This helps to keep stale object
479: files from polluting the build if a Makefile "forgets"
480: about one. It also makes it easier to clean up after
481: a build. It's also necessary if you want to use the
482: same source tree for multiple machines.
1.123 jmc 483: To use object directories with build.sh:
484: a) invoke build.sh with the "-M" or "-O" options.
485: To use object directories without using build.sh:
1.1 abs 486: a) cd /usr/src ; make cleandir
1.2 mrg 487: b) Add "OBJMACHINE=yes" to /etc/mk.conf
488: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 489: d) cd /usr/src ; make build
1.2 mrg 490: Note that running "make obj" in a directory will create
491: in obj.$MACHINE directory.
1.1 abs 492: Build to a DESTDIR:
1.123 jmc 493: This helps to keep old installed files (especially libraries)
494: from interfering with the new build.
495: To build to a DESTDIR with build.sh, use the "-D" option.
496: To build to a DESTDIR without using build.sh, set the DESTDIR
497: environment variable before running make build. It should be
498: set to the pathname of an initially empty directory.
499: Problems: if you do not use build.sh, you might need to
500: update critical utilities without using DESTDIR since
501: nothing is executed from what is installed in DESTDIR.
502: (See critical utils, below.)
1.1 abs 503: Build often:
504: This keeps critical utilities current enough to not choke
505: on any other part of the source tree that depends on up to
1.123 jmc 506: date functionality. If you use build.sh, you should not have
507: this problem.

1.1 abs 509: What to do if things don't work:
510: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.229.2.1 yamt 511: When things don't work there are usually a few things that commonly
1.1 abs 512: should be done.
513: 1) make includes
514: This should be done automatically by make build.
515: 2) cd share/mk && make install
516: Again, automatically done by make build.
517:
518: Failsafe rebuild of a small part of the tree:
519: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
520: To make sure you rebuild something correctly you want to do
521: something like the following:
522: 1) Make sure the includes and .mk files are up to date.
523: 2) Make sure any program used to build the particular
524: utility is up to date. (yacc, lex, etc...)
525: 3) cd ...path/to/util...
526: make cleandir
527: rm ...all obj directories...
528: make cleandir # yes, again
529: make obj
530: make depend && make
531:
532: Failsafe rebuild of the entire tree:
533: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
534: If you really want to make sure the source tree is clean and
1.2 mrg 535: ready for a build try the following. Note that sourcing /etc/mk.conf
536: (a make(1) Makefile) in this manner is not right, and will not work
537: for anyone who uses any make(1) features in /etc/mk.conf.
