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.
13:
1.257 apb 14: Sections are marked with "^^^^^". After the section on "Recent changes"
15: are several sections containing more general information.

1.258 martin 22: 20141026:
1.259 ! msaitoh 23: A mishap during the import of pppd may cause your corruption
1.258 martin 24: in your cvs directory if you happened to do a cvs update
25: during a short period of time. To fix, just remove the
26: directory src/external/bsd/ppp/dist/pppd completely
27: and let cvs restore it on next update.
28:
1.256 apb 29: 20140721:
30: The src/external/mit/lua/src directory was accidentally created
31: and then deleted in the CVS repository. If you get errors like
32:
33: cvs [update aborted]: cannot open directory
34: /cvsroot/src/external/mit/lua/src: No such file or directory
35:
36: then delete your local copy of that directory tree and try again.
37:
1.255 joerg 38: 20140530:
39: ARM eABI switched to DWARF based exception handling. This requires
40: rebuilding all C++ code. It is strongly advised to do a clean build.
41:
1.251 martin 42: 20140131:
1.253 joerg 43: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 44: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 45: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 46:
1.250 christos 47: 20131227:
48: 1. The new ntpd runs in a restricted mode to prevent amplification
49: attacks. If you need ntpdc to work you need to explicitly enable
50: mode7 in your config file. Make sure you put the necessary restrict
51: statements to avoid being exposed.
52: 2. strncat has moved from lib/libc to common/lib/libc; you might need
53: to make clean in libc
54:
1.249 mrg 55: 20131129:
56: The GMP sources were updated, and builds will likely fail without
57: cleaning their build trees for both tools and in-tree, like below.
58:
1.248 mrg 59: 20131128:
60: The MPC and MPFR sources were updated, and builds may require their
61: tools and in-tree directories cleaned for successful updates.
62:
1.246 martin 63: 20130605:
1.247 spz 64: The kernel option FAST_IPSEC no longer exists, it's been renamed
65: to IPSEC (and the older IPSEC version removed).
66:
67: 20130605:
1.246 martin 68: Previous freetype installations eroneously installed private
69: header files. If you are building against a non-empty $DESTDIR,
70: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
71:
1.245 mrg 72: 20130531:
73: The xdm update may cause build failure due to xdm.man being
74: in the obj tree. Make sure to ensure any like this:
75: nbmake: nbmake: don't know how to make xdm.man. Stop
76: is fixed by deleting the xdm.man in the obj tree.
77:
1.244 mrg 78: 20130530:
79: Updates of many xsrc packages will leave old .pc files around.
80: Best to clean out the xsrc objdir entirely before rebuilds.
81:
1.242 christos 82: 20130301:
83: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 84: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 85:
1.238 dholland 86: 20120726:
1.241 wiz 87: The update of OpenSSL requires cleaning both the OpenSSL build
88: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 89: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 90: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 91: cause third-party software to link incorrectly and/or crash.
1.238 dholland 92:
1.237 wiz 93: 20120507:
1.241 wiz 94: The database schema for makemandb was changed. You will
1.237 wiz 95: need to update the database using 'makemandb -f' or wait
96: for the next weekly run to fix it.
97:
1.236 bsh 98: 20120319:
99: sys/conf/Makefile.kern.inc has been modified to adjust the
100: size of db_symtab automatically. You need to update dbsym in
101: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
102: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
103: mk.conf.
104:
1.235 joerg 105: 20120216:
1.241 wiz 106: Default for MKCATPAGES changed to NO. Update builds will fail
107: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 108: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 109: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 110: the next run of weekly will fix it.
1.233 joerg 111:
1.232 christos 112: 20111227:
113: If you built between 20111225 and 20111227 you need to remove
114: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
115: bump has been reverted.
116:
1.231 tls 117: 20111125:
118: The "rnd" pseudodevice has been added to sys/conf/std, which
119: means it should no longer be explicitly listed in kernel
120: configuration files. The line "pseudo-device rnd" should be
121: removed from any custom kernel config files users may have.
122:
1.230 tls 123: 20111119:
124: A problem with the datastructures used by the rndctl(8)
125: utility (pointers in datastructures in an array, making 32->64
126: bit compatibility very painful) has been fixed in a
127: non-backwards-compatible way. If you replace your kernel,
128: replace your rndctl executable too.
1.241 wiz 129:
1.229 jym 130: 20111001:
131: the prop_*_send_syscall() functions from proplib(3) have been
132: changed and their new version is not backward compatible with the old
1.241 wiz 133: one. So ensure that all consumers of these functions (currently:
1.229 jym 134: quota2 code and its tests) are updated together with the new lib.
135:
1.228 mrg 136: 20110817:
137: sparc has been changed to use GCC 4.5.3, so any objdir or
138: DESTDIR for them should be deleted before updating.
139:
1.227 riastrad 140: 20110806:
141: i386 and amd64 have been changed to use GCC 4.5.3, so any
142: objdir or DESTDIR for them should be deleted before updating.
143:
1.226 mrg 144: 20110805:
145: The update to GCC 4.5.3 requires a non-trivial portion of
146: the tree to be cleaned. Best to delete both objdir and
147: DESTDIR before running this update. So far, only the
148: sparc64, mips and powerpc platforms have changed.
149:
1.225 matt 150: 20110803:
1.241 wiz 151: The layout of external/public-domain/xz has changed. To do an
1.225 matt 152: update build you will have to remove the contents of the OBJDIR
153: for external/public-domain/xz/bin by hand as the xz entry there
154: is now a directory.
155:
1.223 joerg 156: 20110410:
1.241 wiz 157: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 158: update build you have to clean both tools/binutils and
159: tools/gcc by hand.
1.223 joerg 160:
1.222 plunky 161: 20110328:
162: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 163: ordering issues with "make all". It may be necessary to remove
1.222 plunky 164: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
165: if your update build fails, as the "Xorg" entry there is now a
166: directory.
167:
1.220 joerg 168: 20110121:
1.221 lukem 169: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 170: the build of individual parts of the tree. This is handled
171: correctly by build.sh. Manual builds have to update /usr/share/mk
172: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 173:
1.217 jruoho 174: 20101217:
175: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 176: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 177: group(5) in order to make the program work with existing setups.
178:
1.216 christos 179: 20101125:
180: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 181: variables with names that contain '='. Revision 1.18 of env.c
182: assumed that this was allowed. Installing a new libc with an
1.216 christos 183: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
184: break which affects the autoconf tests for dependency finding,
185: so building gcc will end up printing:
186: checking dependency style of gcc... none
187: configure: error: no usable dependency style found
188: Fix it by rebuilding and re-installing env.
1.138 lukem 189:
1.215 mrg 190: 20101119:
191: Recent Xorg updates in xsrc/external/mit/ may cause various build
192: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
193: have any build problems with xsrc, or problems with mismatched
194: versions between xorg-server and drivers.
195:
1.213 jmmv 196: 20100604:
197: The update of ATF to 0.9 causes old tests written in shell to fail
198: unless they are rebuilt. If you are building with MKUPDATE=yes,
199: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
200: trees by hand.
201:
1.211 tnozaki 202: 20100522:
1.212 mrg 203: Recent Xorg updates in xsrc/external/mit/ will cause various build
204: problems. Delete your entire DESTDIR and OBJDIR if you have any
205: build problems with xsrc.
206:
207: 20100522:
1.211 tnozaki 208: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 209: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 210:
1.210 christos 211: 20100520:
1.241 wiz 212: The location of the xkb compiled descriptions has changed. Please
1.210 christos 213: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
214:
1.209 njoly 215: 20100222:
216: The shared objects file extension has been changed from .so to
217: .pico, in order to avoid conflicts with shared libraries names
218: libXX.so. All now stale regular .so files can be removed from
219: your object directories.
220:
1.208 roy 221: 20100204:
222: The termcap database has been removed from the sources,
223: but has not been marked obsolete so it is not removed
224: from the system when upgrading.
225: As such, you will need to remove them from your object
226: and destination directories.
227:
1.203 dyoung 228: 20091101:
1.205 dholland 229: After updating, it may be necessary to make the 'cleandir'
230: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
231: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
232: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 233:
1.202 mrg 234: 20091001:
1.206 dholland 235: On amd64 you must rebuild tools (to get the new binutils)
236: before building a kernel, or the build fails on cpufunc.S.
237:
238: 20091001:
1.202 mrg 239: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
240: symlink, failing the build. Delete the link, and the subdir
241: it is in, and retry your build.
242:
1.201 dsl 243: 20090718:
244: libc build changed so that strchr() provides the extra entry
1.241 wiz 245: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 246: may fail because the archive contains the unwanted index.o.
247: (Similarly for strrchr() and rindex().)
248:
1.198 mrg 249: 20090709:
250: Native Xorg was upgraded again. Builds will probably fail again
251: without a clean objdir, at least for src/external/mit/xorg.
252:
1.197 mrg 253: 20090616:
254: Native Xorg was upgraded. Builds will need a clean objdir for
255: src/external/mit/xorg. Upgrading a system from sets will not
256: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
257: subdirectory has been changed into a file, and this needs to
258: be manually "rm -r"'ed before installing xbase.tgz.
259:
1.195 perry 260: 20090501:
261: Several new functions were added to string.h/libc, and this
262: can cause autoconf problems during the tool build for people
1.241 wiz 263: who fail to clean out their tools objects properly. If you
1.195 perry 264: note messages about stpcpy, stpncpy or strnlen accompanying a
265: failure during the tool build, clean out all your tools
266: objects and start again.
267:
1.194 mrg 268: 20090325:
269: The i386 port was switched to i486 default toolchain. This requires
270: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
271:
1.192 skrll 272: 20090126:
1.241 wiz 273: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 274: need to 'rm -f __posix_fadvise50.*' in the libc build directory
275: to avoid using the old assembly stub.
1.192 skrll 276:
1.191 joerg 277: 20090202:
278: pkg_install now depends on the pkgdb cache for automatic conflict
279: detection. It is recommented to rebuild the cache with
280: ``pkg_admin rebuild''.
281:
1.184 christos 282: 20090110:
1.241 wiz 283: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
284: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 285: This is needed even in the MODULAR kernel because there is
286: conditionally compiled code in rtsock.c.
1.184 christos 287: 2. make sure build.sh completes and the binaries in a chroot work
288: before installing.
289: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 290: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 291: are installed properly, and start building libraries first libc
292: and libutil, install them and then continue building all the
1.241 wiz 293: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 294: the new libraries are installed, you can restart the build.
295: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 296: rebuild the required packages to update their shared libraries.
297: Any package you rebuild will require rebuilding all the packages
298: that depend on it.
1.186 christos 299: 5. Next time you run pwd_mkdb with the new binary, the file
300: will be upgraded and it will not be backwards compatible.
1.190 apb 301: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
302: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 303: for utmp. You are better off removing the old files after
1.190 apb 304: upgrading. The automated clearing of /var/run during
305: boot, and the automated rotating of files in /var/log by
306: newsyslog(8), may mean that you do not have to remove the
307: files manually.
308: 7. The optional accounting file (/var/account/acct, see
309: accton(8)) has not been versioned, and will need to be
310: removed. The automatic rotation of the accounting file by
311: /etc/daily limits the bad consequences of failure to remove
312: the file.
1.196 dholland 313: 8. Application software that writes time_t to binary files on
1.241 wiz 314: disk will break or need attention. Most notably: if you are
1.196 dholland 315: using PostgreSQL < 8.4, you need to dump your databases,
316: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 317:
1.183 pgoyette 318: 20081219:
319: config(1) has been updated, and one of the files it creates -
320: swapnetbsd.o - has changed format. You need to rebuild config
321: (done automatically by build.sh) and then you need to rerun
322: config on all kernel configuration files before rebuilding those
323: kernels.
324:
1.181 cube 325: 20081205:
326: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
327: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
328: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 329:
1.179 tsutsui 330: 20081122:
1.182 tsutsui 331: On i386, various kernel options(4) in GENERIC including
1.180 wiz 332: file systems have been disabled and moved into kernel modules.
333: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 334: following files as well as a new GENERIC kernel:
335:
336: - build and install kernel modules from src/sys/modules
337:
338: - install the latest bootloader, which will load a module
1.180 wiz 339: for the file system from which the kernel is loaded automatically
1.179 tsutsui 340:
1.180 wiz 341: If you have to load your kernel from a file system which is not of
342: the same type as the root file system, you have to load the necessary
343: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 344:
1.178 lukem 345: 20080827:
346: If you built and installed a libc from sources between
347: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
348: which results in false errors reported by lint(1).
349: Since this breaks the libc build itself, manual help is
1.180 wiz 350: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 351: $ (cd lib/libc && make MKLINT=no dependall install)
352:
1.177 christos 353: 20080813:
354: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 355: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 356:
1.200 dholland 357: 20080802:
358: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 359: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 360: for -current.
361:
362: Threaded programs (using libpthread) and C++ programs (using
363: libstdc++) compiled after 20070907 and before 20080802 need to
364: be recompiled.
365:
366: One way to find affected pkgsrc packages:
367:
368: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
369: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
370:
1.175 simonb 371: 20080731:
372: WAPBL (metadata journaling support) has been added, but at this
373: time isn't backwards compatible with pre-WAPBL aware kernels
374: and userland (fsck_ffs in particular). Please make sure you
375: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 376: especially an uncleanly mounted journaled filesystem. WAPBL
377: also requires the super block to be in the UFS2 format. You
378: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 379:
1.174 lukem 380: 20080721:
381: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
382: isn't defined.
383:
1.173 freza 384: 20080531:
1.241 wiz 385: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
386: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 387: utility needs to be rebuilt and reinstalled as older binaries
1.241 wiz 388: won't work correctly. The following sequence of commands:
1.173 freza 389:
390: $ (cd sys/sys/ && nbmake-$arch includes)
391: $ (cd sbin/drvctl/ && nbmake-$arch clean)
392: $ (cd sbin/drvctl/ && nbmake-$arch all)
393:
394: leaves new drvctl utility in sbin/drvctl build directory.

438: enumerate interfaces was fixed. The bug began to cause
439: problems after 20070911 when the kernel's SIOCGIFCONF
440: implementation was repaired. From 20070529 to 20070911 racoon

442: normal kernel/userspace version matching hygiene is not
443: sufficient to avoid this problem.) Ensure that both kernel

1.161 dsl 452: 20070422:
453: The way OS emulations lookup filenames inside the emulation root
454: has been changed. Rather than modify the pathname (and copy back
455: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 456: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 457: root file system will be relative to that file system - unless they
1.161 dsl 458: start /../ this is useful when the emulated root is a real install

484: The threading model was changed when the newlock2 branch
485: was merged to NetBSD-current. If you boot with a new
486: kernel (version 4.99.10), then you also need a new pthread
487: library (/usr/lib/libpthread.so.0.7). If you boot with
488: an old kernel, then you need the old pthread library
489: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
490: the pthread library in sync, old threaded applications should

1.1 abs 532: Hints for a more successful build:
533: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 534: Use build.sh, but do not use its "expert mode":
1.132 jmmv 535: This will automatically build the tools in the
1.123 jmc 536: correct order, and it will keep the tools and the
537: new build products from interfering with the running
538: system. This will allow you to ignore most of the
539: other advice in this file.
1.2 mrg 540: Build a new kernel first:
541: This makes sure that any new system calls or features
542: expected by the new userland will be present. This
543: helps to avoid critical errors when upgrading.
1.1 abs 544: Use object directories:
545: This helps to keep stale object
546: files from polluting the build if a Makefile "forgets"
547: about one. It also makes it easier to clean up after
548: a build. It's also necessary if you want to use the
549: same source tree for multiple machines.
1.123 jmc 550: To use object directories with build.sh:
551: a) invoke build.sh with the "-M" or "-O" options.
552: To use object directories without using build.sh:
1.1 abs 553: a) cd /usr/src ; make cleandir
1.2 mrg 554: b) Add "OBJMACHINE=yes" to /etc/mk.conf
555: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 556: d) cd /usr/src ; make build
1.2 mrg 557: Note that running "make obj" in a directory will create
558: in obj.$MACHINE directory.
1.1 abs 559: Build to a DESTDIR:
1.123 jmc 560: This helps to keep old installed files (especially libraries)
561: from interfering with the new build.
562: To build to a DESTDIR with build.sh, use the "-D" option.
563: To build to a DESTDIR without using build.sh, set the DESTDIR
564: environment variable before running make build. It should be
565: set to the pathname of an initially empty directory.
566: Problems: if you do not use build.sh, you might need to
567: update critical utilities without using DESTDIR since
568: nothing is executed from what is installed in DESTDIR.
569: (See critical utils, below.)
1.1 abs 570: Build often:
571: This keeps critical utilities current enough to not choke
572: on any other part of the source tree that depends on up to
1.123 jmc 573: date functionality. If you use build.sh, you should not have
574: this problem.

1.1 abs 576: What to do if things don't work:
577: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 578: When things don't work there are usually a few things that commonly
1.1 abs 579: should be done.
580: 1) make includes
581: This should be done automatically by make build.
582: 2) cd share/mk && make install
583: Again, automatically done by make build.
584:
585: Failsafe rebuild of a small part of the tree:
586: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
587: To make sure you rebuild something correctly you want to do
588: something like the following:
589: 1) Make sure the includes and .mk files are up to date.
590: 2) Make sure any program used to build the particular
591: utility is up to date. (yacc, lex, etc...)
592: 3) cd ...path/to/util...
593: make cleandir
594: rm ...all obj directories...
595: make cleandir # yes, again
596: make obj
597: make depend && make
598:
599: Failsafe rebuild of the entire tree:
600: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
601: If you really want to make sure the source tree is clean and
1.2 mrg 602: ready for a build try the following. Note that sourcing /etc/mk.conf
603: (a make(1) Makefile) in this manner is not right, and will not work
