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.

1.256 ! apb 19: 20140721:
! 20: The src/external/mit/lua/src directory was accidentally created
! 21: and then deleted in the CVS repository. If you get errors like
! 22:
! 23: cvs [update aborted]: cannot open directory
! 24: /cvsroot/src/external/mit/lua/src: No such file or directory
! 25:
! 26: then delete your local copy of that directory tree and try again.

1.255 joerg 28: 20140530:
29: ARM eABI switched to DWARF based exception handling. This requires
30: rebuilding all C++ code. It is strongly advised to do a clean build.
31:
1.251 martin 32: 20140131:
1.253 joerg 33: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 34: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 35: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 36:
1.250 christos 37: 20131227:
38: 1. The new ntpd runs in a restricted mode to prevent amplification
39: attacks. If you need ntpdc to work you need to explicitly enable
40: mode7 in your config file. Make sure you put the necessary restrict
41: statements to avoid being exposed.
42: 2. strncat has moved from lib/libc to common/lib/libc; you might need
43: to make clean in libc
44:
1.249 mrg 45: 20131129:
46: The GMP sources were updated, and builds will likely fail without
47: cleaning their build trees for both tools and in-tree, like below.
48:
1.248 mrg 49: 20131128:
50: The MPC and MPFR sources were updated, and builds may require their
51: tools and in-tree directories cleaned for successful updates.
52:
1.246 martin 53: 20130605:
1.247 spz 54: The kernel option FAST_IPSEC no longer exists, it's been renamed
55: to IPSEC (and the older IPSEC version removed).
56:
57: 20130605:
1.246 martin 58: Previous freetype installations eroneously installed private
59: header files. If you are building against a non-empty $DESTDIR,
60: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
61:
1.245 mrg 62: 20130531:
63: The xdm update may cause build failure due to xdm.man being
64: in the obj tree. Make sure to ensure any like this:
65: nbmake: nbmake: don't know how to make xdm.man. Stop
66: is fixed by deleting the xdm.man in the obj tree.
67:
1.244 mrg 68: 20130530:
69: Updates of many xsrc packages will leave old .pc files around.
70: Best to clean out the xsrc objdir entirely before rebuilds.
71:
1.242 christos 72: 20130301:
73: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 74: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 75:
1.238 dholland 76: 20120726:
1.241 wiz 77: The update of OpenSSL requires cleaning both the OpenSSL build
78: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 79: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 80: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 81: cause third-party software to link incorrectly and/or crash.
1.238 dholland 82:
1.237 wiz 83: 20120507:
1.241 wiz 84: The database schema for makemandb was changed. You will
1.237 wiz 85: need to update the database using 'makemandb -f' or wait
86: for the next weekly run to fix it.
87:
1.236 bsh 88: 20120319:
89: sys/conf/Makefile.kern.inc has been modified to adjust the
90: size of db_symtab automatically. You need to update dbsym in
91: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
92: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
93: mk.conf.
94:
1.235 joerg 95: 20120216:
1.241 wiz 96: Default for MKCATPAGES changed to NO. Update builds will fail
97: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 98: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 99: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 100: the next run of weekly will fix it.
1.233 joerg 101:
1.232 christos 102: 20111227:
103: If you built between 20111225 and 20111227 you need to remove
104: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
105: bump has been reverted.
106:
1.231 tls 107: 20111125:
108: The "rnd" pseudodevice has been added to sys/conf/std, which
109: means it should no longer be explicitly listed in kernel
110: configuration files. The line "pseudo-device rnd" should be
111: removed from any custom kernel config files users may have.
112:
1.230 tls 113: 20111119:
114: A problem with the datastructures used by the rndctl(8)
115: utility (pointers in datastructures in an array, making 32->64
116: bit compatibility very painful) has been fixed in a
117: non-backwards-compatible way. If you replace your kernel,
118: replace your rndctl executable too.
1.241 wiz 119:
1.229 jym 120: 20111001:
121: the prop_*_send_syscall() functions from proplib(3) have been
122: changed and their new version is not backward compatible with the old
1.241 wiz 123: one. So ensure that all consumers of these functions (currently:
1.229 jym 124: quota2 code and its tests) are updated together with the new lib.
125:
1.228 mrg 126: 20110817:
127: sparc has been changed to use GCC 4.5.3, so any objdir or
128: DESTDIR for them should be deleted before updating.
129:
1.227 riastrad 130: 20110806:
131: i386 and amd64 have been changed to use GCC 4.5.3, so any
132: objdir or DESTDIR for them should be deleted before updating.
133:
1.226 mrg 134: 20110805:
135: The update to GCC 4.5.3 requires a non-trivial portion of
136: the tree to be cleaned. Best to delete both objdir and
137: DESTDIR before running this update. So far, only the
138: sparc64, mips and powerpc platforms have changed.
139:
1.225 matt 140: 20110803:
1.241 wiz 141: The layout of external/public-domain/xz has changed. To do an
1.225 matt 142: update build you will have to remove the contents of the OBJDIR
143: for external/public-domain/xz/bin by hand as the xz entry there
144: is now a directory.
145:
1.223 joerg 146: 20110410:
1.241 wiz 147: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 148: update build you have to clean both tools/binutils and
149: tools/gcc by hand.
1.223 joerg 150:
1.222 plunky 151: 20110328:
152: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 153: ordering issues with "make all". It may be necessary to remove
1.222 plunky 154: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
155: if your update build fails, as the "Xorg" entry there is now a
156: directory.
157:
1.220 joerg 158: 20110121:
1.221 lukem 159: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 160: the build of individual parts of the tree. This is handled
161: correctly by build.sh. Manual builds have to update /usr/share/mk
162: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 163:
1.217 jruoho 164: 20101217:
165: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 166: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 167: group(5) in order to make the program work with existing setups.
168:
1.216 christos 169: 20101125:
170: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 171: variables with names that contain '='. Revision 1.18 of env.c
172: assumed that this was allowed. Installing a new libc with an
1.216 christos 173: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
174: break which affects the autoconf tests for dependency finding,
175: so building gcc will end up printing:
176: checking dependency style of gcc... none
177: configure: error: no usable dependency style found
178: Fix it by rebuilding and re-installing env.
1.138 lukem 179:
1.215 mrg 180: 20101119:
181: Recent Xorg updates in xsrc/external/mit/ may cause various build
182: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
183: have any build problems with xsrc, or problems with mismatched
184: versions between xorg-server and drivers.
185:
1.213 jmmv 186: 20100604:
187: The update of ATF to 0.9 causes old tests written in shell to fail
188: unless they are rebuilt. If you are building with MKUPDATE=yes,
189: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
190: trees by hand.
191:
1.211 tnozaki 192: 20100522:
1.212 mrg 193: Recent Xorg updates in xsrc/external/mit/ will cause various build
194: problems. Delete your entire DESTDIR and OBJDIR if you have any
195: build problems with xsrc.
196:
197: 20100522:
1.211 tnozaki 198: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 199: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 200:
1.210 christos 201: 20100520:
1.241 wiz 202: The location of the xkb compiled descriptions has changed. Please
1.210 christos 203: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
204:
1.209 njoly 205: 20100222:
206: The shared objects file extension has been changed from .so to
207: .pico, in order to avoid conflicts with shared libraries names
208: libXX.so. All now stale regular .so files can be removed from
209: your object directories.
210:
1.208 roy 211: 20100204:
212: The termcap database has been removed from the sources,
213: but has not been marked obsolete so it is not removed
214: from the system when upgrading.
215: As such, you will need to remove them from your object
216: and destination directories.
217:
1.203 dyoung 218: 20091101:
1.205 dholland 219: After updating, it may be necessary to make the 'cleandir'
220: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
221: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
222: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 223:
1.202 mrg 224: 20091001:
1.206 dholland 225: On amd64 you must rebuild tools (to get the new binutils)
226: before building a kernel, or the build fails on cpufunc.S.
227:
228: 20091001:
1.202 mrg 229: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
230: symlink, failing the build. Delete the link, and the subdir
231: it is in, and retry your build.
232:
1.201 dsl 233: 20090718:
234: libc build changed so that strchr() provides the extra entry
1.241 wiz 235: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 236: may fail because the archive contains the unwanted index.o.
237: (Similarly for strrchr() and rindex().)
238:
1.198 mrg 239: 20090709:
240: Native Xorg was upgraded again. Builds will probably fail again
241: without a clean objdir, at least for src/external/mit/xorg.
242:
1.197 mrg 243: 20090616:
244: Native Xorg was upgraded. Builds will need a clean objdir for
245: src/external/mit/xorg. Upgrading a system from sets will not
246: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
247: subdirectory has been changed into a file, and this needs to
248: be manually "rm -r"'ed before installing xbase.tgz.
249:
1.195 perry 250: 20090501:
251: Several new functions were added to string.h/libc, and this
252: can cause autoconf problems during the tool build for people
1.241 wiz 253: who fail to clean out their tools objects properly. If you
1.195 perry 254: note messages about stpcpy, stpncpy or strnlen accompanying a
255: failure during the tool build, clean out all your tools
256: objects and start again.
257:
1.194 mrg 258: 20090325:
259: The i386 port was switched to i486 default toolchain. This requires
260: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
261:
1.192 skrll 262: 20090126:
1.241 wiz 263: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 264: need to 'rm -f __posix_fadvise50.*' in the libc build directory
265: to avoid using the old assembly stub.
1.192 skrll 266:
1.191 joerg 267: 20090202:
268: pkg_install now depends on the pkgdb cache for automatic conflict
269: detection. It is recommented to rebuild the cache with
270: ``pkg_admin rebuild''.
271:
1.184 christos 272: 20090110:
1.241 wiz 273: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
274: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 275: This is needed even in the MODULAR kernel because there is
276: conditionally compiled code in rtsock.c.
1.184 christos 277: 2. make sure build.sh completes and the binaries in a chroot work
278: before installing.
279: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 280: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 281: are installed properly, and start building libraries first libc
282: and libutil, install them and then continue building all the
1.241 wiz 283: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 284: the new libraries are installed, you can restart the build.
285: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 286: rebuild the required packages to update their shared libraries.
287: Any package you rebuild will require rebuilding all the packages
288: that depend on it.
1.186 christos 289: 5. Next time you run pwd_mkdb with the new binary, the file
290: will be upgraded and it will not be backwards compatible.
1.190 apb 291: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
292: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 293: for utmp. You are better off removing the old files after
1.190 apb 294: upgrading. The automated clearing of /var/run during
295: boot, and the automated rotating of files in /var/log by
296: newsyslog(8), may mean that you do not have to remove the
297: files manually.
298: 7. The optional accounting file (/var/account/acct, see
299: accton(8)) has not been versioned, and will need to be
300: removed. The automatic rotation of the accounting file by
301: /etc/daily limits the bad consequences of failure to remove
302: the file.
1.196 dholland 303: 8. Application software that writes time_t to binary files on
1.241 wiz 304: disk will break or need attention. Most notably: if you are
1.196 dholland 305: using PostgreSQL < 8.4, you need to dump your databases,
306: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 307:
1.183 pgoyette 308: 20081219:
309: config(1) has been updated, and one of the files it creates -
310: swapnetbsd.o - has changed format. You need to rebuild config
311: (done automatically by build.sh) and then you need to rerun
312: config on all kernel configuration files before rebuilding those
313: kernels.
314:
1.181 cube 315: 20081205:
316: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
317: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
318: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 319:
1.179 tsutsui 320: 20081122:
1.182 tsutsui 321: On i386, various kernel options(4) in GENERIC including
1.180 wiz 322: file systems have been disabled and moved into kernel modules.
323: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 324: following files as well as a new GENERIC kernel:
325:
326: - build and install kernel modules from src/sys/modules
327:
328: - install the latest bootloader, which will load a module
1.180 wiz 329: for the file system from which the kernel is loaded automatically
1.179 tsutsui 330:
1.180 wiz 331: If you have to load your kernel from a file system which is not of
332: the same type as the root file system, you have to load the necessary
333: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 334:
1.178 lukem 335: 20080827:
336: If you built and installed a libc from sources between
337: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
338: which results in false errors reported by lint(1).
339: Since this breaks the libc build itself, manual help is
1.180 wiz 340: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 341: $ (cd lib/libc && make MKLINT=no dependall install)
342:
1.177 christos 343: 20080813:
344: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 345: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 346:
1.200 dholland 347: 20080802:
348: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 349: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 350: for -current.
351:
352: Threaded programs (using libpthread) and C++ programs (using
353: libstdc++) compiled after 20070907 and before 20080802 need to
354: be recompiled.
355:
356: One way to find affected pkgsrc packages:
357:
358: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
359: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
360:
1.175 simonb 361: 20080731:
362: WAPBL (metadata journaling support) has been added, but at this
363: time isn't backwards compatible with pre-WAPBL aware kernels
364: and userland (fsck_ffs in particular). Please make sure you
365: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 366: especially an uncleanly mounted journaled filesystem. WAPBL
367: also requires the super block to be in the UFS2 format. You
368: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 369:
1.174 lukem 370: 20080721:
371: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
372: isn't defined.
373:
1.173 freza 374: 20080531:
1.241 wiz 375: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
376: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 377: utility needs to be rebuilt and reinstalled as older binaries
1.241 wiz 378: won't work correctly. The following sequence of commands:
1.173 freza 379:
380: $ (cd sys/sys/ && nbmake-$arch includes)
381: $ (cd sbin/drvctl/ && nbmake-$arch clean)
382: $ (cd sbin/drvctl/ && nbmake-$arch all)
383:
384: leaves new drvctl utility in sbin/drvctl build directory.
385:
1.172 lukem 386: 20080503:
387: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
388:
1.171 he 389: 20080521:
390: For a while, unprivileged UPDATE builds would fail to
391: succeed at the checkflist stage, complaining that
392: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
393: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
394: If you already hit this problem, update the .mk file,

429: problems after 20070911 when the kernel's SIOCGIFCONF
430: implementation was repaired. From 20070529 to 20070911 racoon

444: has been changed. Rather than modify the pathname (and copy back
445: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 446: root. One side effect is that absolute symlinks inside the emulated

476: kernel (version 4.99.10), then you also need a new pthread

1.1 abs 522: Hints for a more successful build:
523: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 524: Use build.sh, but do not use its "expert mode":
1.132 jmmv 525: This will automatically build the tools in the
1.123 jmc 526: correct order, and it will keep the tools and the
527: new build products from interfering with the running
528: system. This will allow you to ignore most of the
529: other advice in this file.
1.2 mrg 530: Build a new kernel first:
531: This makes sure that any new system calls or features
532: expected by the new userland will be present. This
533: helps to avoid critical errors when upgrading.
1.1 abs 534: Use object directories:
535: This helps to keep stale object
536: files from polluting the build if a Makefile "forgets"
537: about one. It also makes it easier to clean up after
538: a build. It's also necessary if you want to use the
539: same source tree for multiple machines.
1.123 jmc 540: To use object directories with build.sh:
541: a) invoke build.sh with the "-M" or "-O" options.
542: To use object directories without using build.sh:
1.1 abs 543: a) cd /usr/src ; make cleandir
1.2 mrg 544: b) Add "OBJMACHINE=yes" to /etc/mk.conf
545: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 546: d) cd /usr/src ; make build
1.2 mrg 547: Note that running "make obj" in a directory will create
548: in obj.$MACHINE directory.
1.1 abs 549: Build to a DESTDIR:
1.123 jmc 550: This helps to keep old installed files (especially libraries)
551: from interfering with the new build.
552: To build to a DESTDIR with build.sh, use the "-D" option.
553: To build to a DESTDIR without using build.sh, set the DESTDIR
554: environment variable before running make build. It should be
555: set to the pathname of an initially empty directory.
556: Problems: if you do not use build.sh, you might need to
557: update critical utilities without using DESTDIR since
558: nothing is executed from what is installed in DESTDIR.
559: (See critical utils, below.)
1.1 abs 560: Build often:
561: This keeps critical utilities current enough to not choke
562: on any other part of the source tree that depends on up to
1.123 jmc 563: date functionality. If you use build.sh, you should not have
564: this problem.

567: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 568: When things don't work there are usually a few things that commonly
1.1 abs 569: should be done.
570: 1) make includes
571: This should be done automatically by make build.
572: 2) cd share/mk && make install
573: Again, automatically done by make build.
574:
575: Failsafe rebuild of a small part of the tree:
576: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
577: To make sure you rebuild something correctly you want to do
578: something like the following:
579: 1) Make sure the includes and .mk files are up to date.
580: 2) Make sure any program used to build the particular
581: utility is up to date. (yacc, lex, etc...)
582: 3) cd ...path/to/util...
583: make cleandir
584: rm ...all obj directories...
585: make cleandir # yes, again
586: make obj
587: make depend && make
588:
589: Failsafe rebuild of the entire tree:
590: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
591: If you really want to make sure the source tree is clean and
1.2 mrg 592: ready for a build try the following. Note that sourcing /etc/mk.conf
593: (a make(1) Makefile) in this manner is not right, and will not work
