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:
1.238 ! dholland 19: 20120726:
! 20: The update of openssl requires cleaning both the openssl build
! 21: directory and DESTDIR; update builds done without taking these
! 22: steps may fail, or if not, have been observed to cause
! 23: third-party software to link incorrectly.
! 24:
1.237 wiz 25: 20120507:
26: The database schema for makemandb was changed. You will
27: need to update the database using 'makemandb -f' or wait
28: for the next weekly run to fix it.
29:
1.236 bsh 30: 20120319:
31: sys/conf/Makefile.kern.inc has been modified to adjust the
32: size of db_symtab automatically. You need to update dbsym in
33: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
34: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
35: mk.conf.
36:
1.235 joerg 37: 20120216:
1.234 spz 38: Default for MKCATPAGES changed to NO. Update builds will fail
1.235 joerg 39: unless DESTDIR is cleaned manually. If you built between 20120207
40: and 20120216, daily and weekly could have created an unreable
41: /var/db/man.db index for apropos. Running makemandb -f or
42: the next run of weekly will fix it.
1.233 joerg 43:
1.232 christos 44: 20111227:
45: If you built between 20111225 and 20111227 you need to remove
46: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
47: bump has been reverted.
48:
1.231 tls 49: 20111125:
50: The "rnd" pseudodevice has been added to sys/conf/std, which
51: means it should no longer be explicitly listed in kernel
52: configuration files. The line "pseudo-device rnd" should be
53: removed from any custom kernel config files users may have.
54:
1.230 tls 55: 20111119:
56: A problem with the datastructures used by the rndctl(8)
57: utility (pointers in datastructures in an array, making 32->64
58: bit compatibility very painful) has been fixed in a
59: non-backwards-compatible way. If you replace your kernel,
60: replace your rndctl executable too.
61:
1.229 jym 62: 20111001:
63: the prop_*_send_syscall() functions from proplib(3) have been
64: changed and their new version is not backward compatible with the old
65: one. So ensure that all consumers of these functions (currently:
66: quota2 code and its tests) are updated together with the new lib.
67:
1.228 mrg 68: 20110817:
69: sparc has been changed to use GCC 4.5.3, so any objdir or
70: DESTDIR for them should be deleted before updating.
71:
1.227 riastrad 72: 20110806:
73: i386 and amd64 have been changed to use GCC 4.5.3, so any
74: objdir or DESTDIR for them should be deleted before updating.
75:
1.226 mrg 76: 20110805:
77: The update to GCC 4.5.3 requires a non-trivial portion of
78: the tree to be cleaned. Best to delete both objdir and
79: DESTDIR before running this update. So far, only the
80: sparc64, mips and powerpc platforms have changed.
81:
1.225 matt 82: 20110803:
83: The layout of external/public-domain/xz has changed. To do an
84: update build you will have to remove the contents of the OBJDIR
85: for external/public-domain/xz/bin by hand as the xz entry there
86: is now a directory.
87:
1.223 joerg 88: 20110410:
1.224 dholland 89: The configuration of src/tools/gcc has changed. To do an
90: update build you have to clean both tools/binutils and
91: tools/gcc by hand.
1.223 joerg 92:
1.222 plunky 93: 20110328:
94: Building the Xorg binary was moved into a subdirectory to fix
95: ordering issues with "make all". It may be necessary to remove
96: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
97: if your update build fails, as the "Xorg" entry there is now a
98: directory.
99:
1.220 joerg 100: 20110121:
1.221 lukem 101: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 102: the build of individual parts of the tree. This is handled
103: correctly by build.sh. Manual builds have to update /usr/share/mk
104: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 105:
1.217 jruoho 106: 20101217:
107: The tcpdump(8) program was changed to drop privileges and chroot(2)
108: by default. It may be necessary to manually update passwd(5) and
109: group(5) in order to make the program work with existing setups.
110:
1.216 christos 111: 20101125:
112: The latest changes to setenv(3) dissallow setting environment
113: variables with names that contain '='. Revision 1.18 of env.c
114: assumed that this was allowed. Installing a new libc with an
115: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
116: break which affects the autoconf tests for dependency finding,
117: so building gcc will end up printing:
118: checking dependency style of gcc... none
119: configure: error: no usable dependency style found
120: Fix it by rebuilding and re-installing env.
1.138 lukem 121:
1.215 mrg 122: 20101119:
123: Recent Xorg updates in xsrc/external/mit/ may cause various build
124: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
125: have any build problems with xsrc, or problems with mismatched
126: versions between xorg-server and drivers.
127:
1.213 jmmv 128: 20100604:
129: The update of ATF to 0.9 causes old tests written in shell to fail
130: unless they are rebuilt. If you are building with MKUPDATE=yes,
131: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
132: trees by hand.
133:
1.211 tnozaki 134: 20100522:
1.212 mrg 135: Recent Xorg updates in xsrc/external/mit/ will cause various build
136: problems. Delete your entire DESTDIR and OBJDIR if you have any
137: build problems with xsrc.
138:
139: 20100522:
1.211 tnozaki 140: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 141: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 142:
1.210 christos 143: 20100520:
144: The location of the xkb compiled descriptions has changed. Please
145: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
146:
1.209 njoly 147: 20100222:
148: The shared objects file extension has been changed from .so to
149: .pico, in order to avoid conflicts with shared libraries names
150: libXX.so. All now stale regular .so files can be removed from
151: your object directories.
152:
1.208 roy 153: 20100204:
154: The termcap database has been removed from the sources,
155: but has not been marked obsolete so it is not removed
156: from the system when upgrading.
157: As such, you will need to remove them from your object
158: and destination directories.
159:
1.203 dyoung 160: 20091101:
1.205 dholland 161: After updating, it may be necessary to make the 'cleandir'
162: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
163: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
164: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 165:
1.202 mrg 166: 20091001:
1.206 dholland 167: On amd64 you must rebuild tools (to get the new binutils)
168: before building a kernel, or the build fails on cpufunc.S.
169:
170: 20091001:
1.202 mrg 171: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
172: symlink, failing the build. Delete the link, and the subdir
173: it is in, and retry your build.
174:
1.201 dsl 175: 20090718:
176: libc build changed so that strchr() provides the extra entry
177: point for index(). Update build of libc.a (and libc_pic.a)
178: may fail because the archive contains the unwanted index.o.
179: (Similarly for strrchr() and rindex().)
180:
1.198 mrg 181: 20090709:
182: Native Xorg was upgraded again. Builds will probably fail again
183: without a clean objdir, at least for src/external/mit/xorg.
184:
1.197 mrg 185: 20090616:
186: Native Xorg was upgraded. Builds will need a clean objdir for
187: src/external/mit/xorg. Upgrading a system from sets will not
188: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
189: subdirectory has been changed into a file, and this needs to
190: be manually "rm -r"'ed before installing xbase.tgz.
191:
1.195 perry 192: 20090501:
193: Several new functions were added to string.h/libc, and this
194: can cause autoconf problems during the tool build for people
195: who fail to clean out their tools objects properly. If you
196: note messages about stpcpy, stpncpy or strnlen accompanying a
197: failure during the tool build, clean out all your tools
198: objects and start again.
199:
1.194 mrg 200: 20090325:
201: The i386 port was switched to i486 default toolchain. This requires
202: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
203:
1.192 skrll 204: 20090126:
1.207 mbalmer 205: The __posix_fadvise50 system call changed assembly stub type. You
206: need to 'rm -f __posix_fadvise50.*' in the libc build directory
207: to avoid using the old assembly stub.
1.192 skrll 208:
1.191 joerg 209: 20090202:
210: pkg_install now depends on the pkgdb cache for automatic conflict
211: detection. It is recommented to rebuild the cache with
212: ``pkg_admin rebuild''.
213:
1.184 christos 214: 20090110:
215: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
216: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 217: This is needed even in the MODULAR kernel because there is
218: conditionally compiled code in rtsock.c.
1.184 christos 219: 2. make sure build.sh completes and the binaries in a chroot work
220: before installing.
221: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 222: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 223: are installed properly, and start building libraries first libc
224: and libutil, install them and then continue building all the
225: libraries in src/lib and src/gnu/lib and install them. Once
226: the new libraries are installed, you can restart the build.
227: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 228: rebuild the required packages to update their shared libraries.
229: Any package you rebuild will require rebuilding all the packages
230: that depend on it.
1.186 christos 231: 5. Next time you run pwd_mkdb with the new binary, the file
232: will be upgraded and it will not be backwards compatible.
1.190 apb 233: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
234: lastlogx(5)) have been versioned, and there is a heuristic
235: for utmp. You are better off removing the old files after
236: upgrading. The automated clearing of /var/run during
237: boot, and the automated rotating of files in /var/log by
238: newsyslog(8), may mean that you do not have to remove the
239: files manually.
240: 7. The optional accounting file (/var/account/acct, see
241: accton(8)) has not been versioned, and will need to be
242: removed. The automatic rotation of the accounting file by
243: /etc/daily limits the bad consequences of failure to remove
244: the file.
1.196 dholland 245: 8. Application software that writes time_t to binary files on
246: disk will break or need attention. Most notably: if you are
247: using PostgreSQL < 8.4, you need to dump your databases,
248: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 249:
1.183 pgoyette 250: 20081219:
251: config(1) has been updated, and one of the files it creates -
252: swapnetbsd.o - has changed format. You need to rebuild config
253: (done automatically by build.sh) and then you need to rerun
254: config on all kernel configuration files before rebuilding those
255: kernels.
256:
1.181 cube 257: 20081205:
258: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
259: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
260: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 261:
1.179 tsutsui 262: 20081122:
1.182 tsutsui 263: On i386, various kernel options(4) in GENERIC including
1.180 wiz 264: file systems have been disabled and moved into kernel modules.
265: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 266: following files as well as a new GENERIC kernel:
267:
268: - build and install kernel modules from src/sys/modules
269:
270: - install the latest bootloader, which will load a module
1.180 wiz 271: for the file system from which the kernel is loaded automatically
1.179 tsutsui 272:
1.180 wiz 273: If you have to load your kernel from a file system which is not of
274: the same type as the root file system, you have to load the necessary
275: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 276:
1.178 lukem 277: 20080827:
278: If you built and installed a libc from sources between
279: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
280: which results in false errors reported by lint(1).
281: Since this breaks the libc build itself, manual help is
1.180 wiz 282: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 283: $ (cd lib/libc && make MKLINT=no dependall install)
284:
1.177 christos 285: 20080813:
286: MKDEBUG build was broken because the .depend files did not know
287: about .go files. You need to remove all .depend files and rebuild.
288:
1.200 dholland 289: 20080802:
290: A regression in binary compatibility for pthread_mutex_t has
291: been fixed. Unfortunately, the price is breaking compatibility
292: for -current.
293:
294: Threaded programs (using libpthread) and C++ programs (using
295: libstdc++) compiled after 20070907 and before 20080802 need to
296: be recompiled.
297:
298: One way to find affected pkgsrc packages:
299:
300: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
301: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
302:
1.175 simonb 303: 20080731:
304: WAPBL (metadata journaling support) has been added, but at this
305: time isn't backwards compatible with pre-WAPBL aware kernels
306: and userland (fsck_ffs in particular). Please make sure you
307: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 308: especially an uncleanly mounted journaled filesystem. WAPBL
309: also requires the super block to be in the UFS2 format. You
310: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 311:
1.174 lukem 312: 20080721:
313: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
314: isn't defined.
315:
1.173 freza 316: 20080531:
317: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
318: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
319: utility needs to be rebuilt and reinstalled as older binaries
320: won't work correctly. The following sequence of commands:
321:
322: $ (cd sys/sys/ && nbmake-$arch includes)
323: $ (cd sbin/drvctl/ && nbmake-$arch clean)
324: $ (cd sbin/drvctl/ && nbmake-$arch all)
325:
326: leaves new drvctl utility in sbin/drvctl build directory.
327:
1.172 lukem 328: 20080503:
329: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
330:
1.171 he 331: 20080521:
332: For a while, unprivileged UPDATE builds would fail to
333: succeed at the checkflist stage, complaining that
334: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
335: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
336: If you already hit this problem, update the .mk file,
337: remove ${DESTDIR}/stand/<arch>, and re-run the build.
338:
1.174 lukem 339: 20080303:
340: Linker warnings are now fatal if $WARNS>0.
341:
1.170 christos 342: 20080126:
343: The posix_fadvise system call has been changed from an assembly
344: stub, to a c file that calls an assembly stub. You need to
345: 'rm -f posix_fadvise.* .depend' in the libc build directory to
346: avoid using the old assembly stub.
347:
1.168 joerg 348: 20071209:
349: The acpiec(4) driver has been split into two attachments. If you
350: get ACPI errors before the attachment, please update your kernel
1.169 wiz 351: configuration file appropriately or see GENERIC for more details.
1.168 joerg 352:
1.166 xtraeme 353: 20071115:
354: The it(4) driver has been renamed to itesio(4) and the old port
355: argument specified in the kernel configuration file is not valid
356: anymore. The itesio(4) driver now uses the Super I/O address port
357: rather than the EC address port. Please update your kernel
1.167 wiz 358: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 359:
1.165 jmmv 360: 20071028:
361: The pccons(4) driver has been removed from the NetBSD/shark port.
362: You need to update any custom kernel configuration file you have
363: to remove any references to pccons (which includes removing the
364: now useless XSERVER option) and replace them with the correct
365: entries for the wscons driver. See the GENERIC configuration file
366: for more details.
367:
1.164 gdt 368: 20070913:
369: A latent bug in dhclient/dhcpd that caused it to be unable to
370: enumerate interfaces was fixed. The bug began to cause
371: problems after 20070911 when the kernel's SIOCGIFCONF
372: implementation was repaired. From 20070529 to 20070911 racoon
373: could not enumerate interfaces. (These are noted because
374: normal kernel/userspace version matching hygiene is not
375: sufficient to avoid this problem.) Ensure that both kernel
376: and userland are from after 20070913.
377:
1.163 joerg 378: 20070703:
1.199 dholland 379: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
380: calls the target-specific strip program, and the logic to pass
381: down STRIP from make has been removed. This requires a
382: re-installation of tools.
1.163 joerg 383:
1.161 dsl 384: 20070422:
385: The way OS emulations lookup filenames inside the emulation root
386: has been changed. Rather than modify the pathname (and copy back
387: to userspace) namei() and lookup() directly check the emulation
388: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 389: root file system will be relative to that file system - unless they
1.161 dsl 390: start /../ this is useful when the emulated root is a real install
391: that has such links.
392: This might affect symlinks that have been added to reference outside
393: the emulated root.
394:
1.160 jmcneill 395: 20070412:
396: The pckbc driver on sgimips IP32 has been removed. Use macekbc
397: instead. See the GENERIC32_IP3x kernel configuration for an
398: example.
399:
1.159 gdt 400: 20070319:
401: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
402: on many platforms due to incorrect flags settings. If you
403: updated and built after about 20070315, do "nbmake-$arch
404: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
405: rebuild of object files that might have been built
406: incorrectly, and ensure that you have at least
407: src/lib/libc/Makefile 1.130.
408:
1.158 dbj 409: 20070210:

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

427: Following the move of string_to_flags() and flags_to_string()
428: from the bin/ls/ sources to libutil, users doing UPDATE builds
429: will need to do a "make cleandir" in
430: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
431: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 432: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
433: as the installation images in distrib/
1.154 he 434: in order to excise stale references to the old stat_flags.h header
435: file in the ls sources -- stat_flags.h has been removed.

1.152 christos 437: 20061108:
438: The configure script used in the src/tools/gcc compiler has been
439: changed to indicate that our libc has ssp support built-in and
440: does not depend on -lssp and -lssp-nonshared. You'll need to
441: make clean in src/tools/gcc first to rebuild the compiler.

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

454: MPACPI is no more. We always configure PCI interrupts using ACPI
455: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
456: to ACPI_SCANPCI. Thanks to work from fvdl.

459: socket(2) has changed, and its system call has been versioned.
460: For userlands with the old version of socket(2), make sure that
461: your kernel has 'options COMPAT_30' set, or else 'bad system call'
462: errors will result.

1.1 abs 464: Hints for a more successful build:
465: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 466: Use build.sh, but do not use its "expert mode":
1.132 jmmv 467: This will automatically build the tools in the
1.123 jmc 468: correct order, and it will keep the tools and the
469: new build products from interfering with the running
470: system. This will allow you to ignore most of the
471: other advice in this file.
1.2 mrg 472: Build a new kernel first:
473: This makes sure that any new system calls or features
474: expected by the new userland will be present. This
475: helps to avoid critical errors when upgrading.
1.1 abs 476: Use object directories:
477: This helps to keep stale object
478: files from polluting the build if a Makefile "forgets"
479: about one. It also makes it easier to clean up after
480: a build. It's also necessary if you want to use the
481: same source tree for multiple machines.
1.123 jmc 482: To use object directories with build.sh:
483: a) invoke build.sh with the "-M" or "-O" options.
484: To use object directories without using build.sh:
1.1 abs 485: a) cd /usr/src ; make cleandir
1.2 mrg 486: b) Add "OBJMACHINE=yes" to /etc/mk.conf
487: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 488: d) cd /usr/src ; make build
1.2 mrg 489: Note that running "make obj" in a directory will create
490: in obj.$MACHINE directory.
1.1 abs 491: Build to a DESTDIR:
1.123 jmc 492: This helps to keep old installed files (especially libraries)
493: from interfering with the new build.
494: To build to a DESTDIR with build.sh, use the "-D" option.
495: To build to a DESTDIR without using build.sh, set the DESTDIR
496: environment variable before running make build. It should be
497: set to the pathname of an initially empty directory.
498: Problems: if you do not use build.sh, you might need to
499: update critical utilities without using DESTDIR since
500: nothing is executed from what is installed in DESTDIR.
501: (See critical utils, below.)
1.1 abs 502: Build often:
503: This keeps critical utilities current enough to not choke
504: on any other part of the source tree that depends on up to
1.123 jmc 505: date functionality. If you use build.sh, you should not have
506: this problem.
1.1 abs 507:
508: What to do if things don't work:
509: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 510: When things don't work there are usually a few things that commonly
1.1 abs 511: should be done.
512: 1) make includes
513: This should be done automatically by make build.
514: 2) cd share/mk && make install
515: Again, automatically done by make build.
516:
517: Failsafe rebuild of a small part of the tree:
518: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
519: To make sure you rebuild something correctly you want to do
520: something like the following:
521: 1) Make sure the includes and .mk files are up to date.
522: 2) Make sure any program used to build the particular
523: utility is up to date. (yacc, lex, etc...)
524: 3) cd ...path/to/util...
525: make cleandir
526: rm ...all obj directories...
527: make cleandir # yes, again
528: make obj
529: make depend && make
530:
531: Failsafe rebuild of the entire tree:
532: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
533: If you really want to make sure the source tree is clean and
1.2 mrg 534: ready for a build try the following. Note that sourcing /etc/mk.conf
535: (a make(1) Makefile) in this manner is not right, and will not work
536: for anyone who uses any make(1) features in /etc/mk.conf.
