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.

1.230 tls 21:
1.263 ! dholland 22: 20150818:
! 23: New acpica requires "make cleandir" in src/external/bsd/acpica
! 24: again.
! 25:
1.262 christos 26: 20150413:
27: New acpica requires "make cleandir" and reinstalling yacc
28: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
29: also "make cleandir" in /usr/src/external/bsd/acpica.
30:
1.261 martin 31: 20150404:
32: Lint changes require a full rebuild of the tool, so make
33: sure to build without -u option to build.sh, or manually
34: do a make cleandir in src/tools/lint1 and
35: src/usr.bin/xlint.
36:
1.260 skrll 37: 20150310:
38: Improvements to openssl for arm mean that update builds of
39: the openssl libraries will fail. A make cleandir in
40: external/bsd/openssl/lib is needed
41:
1.258 martin 42: 20141026:
1.259 msaitoh 43: A mishap during the import of pppd may cause your corruption
1.258 martin 44: in your cvs directory if you happened to do a cvs update
45: during a short period of time. To fix, just remove the
46: directory src/external/bsd/ppp/dist/pppd completely
47: and let cvs restore it on next update.
48:
1.256 apb 49: 20140721:
50: The src/external/mit/lua/src directory was accidentally created
51: and then deleted in the CVS repository. If you get errors like
52:
53: cvs [update aborted]: cannot open directory
54: /cvsroot/src/external/mit/lua/src: No such file or directory
55:
56: then delete your local copy of that directory tree and try again.
57:
1.255 joerg 58: 20140530:
59: ARM eABI switched to DWARF based exception handling. This requires
60: rebuilding all C++ code. It is strongly advised to do a clean build.
61:
1.251 martin 62: 20140131:
1.253 joerg 63: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 64: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 65: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 66:
1.250 christos 67: 20131227:
68: 1. The new ntpd runs in a restricted mode to prevent amplification
69: attacks. If you need ntpdc to work you need to explicitly enable
70: mode7 in your config file. Make sure you put the necessary restrict
71: statements to avoid being exposed.
72: 2. strncat has moved from lib/libc to common/lib/libc; you might need
73: to make clean in libc
74:
1.249 mrg 75: 20131129:
76: The GMP sources were updated, and builds will likely fail without
77: cleaning their build trees for both tools and in-tree, like below.
78:
1.248 mrg 79: 20131128:
80: The MPC and MPFR sources were updated, and builds may require their
81: tools and in-tree directories cleaned for successful updates.
82:
1.246 martin 83: 20130605:
1.247 spz 84: The kernel option FAST_IPSEC no longer exists, it's been renamed
85: to IPSEC (and the older IPSEC version removed).
86:
87: 20130605:
1.246 martin 88: Previous freetype installations eroneously installed private
89: header files. If you are building against a non-empty $DESTDIR,
90: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
91:
1.245 mrg 92: 20130531:
93: The xdm update may cause build failure due to xdm.man being
94: in the obj tree. Make sure to ensure any like this:
95: nbmake: nbmake: don't know how to make xdm.man. Stop
96: is fixed by deleting the xdm.man in the obj tree.
97:
1.244 mrg 98: 20130530:
99: Updates of many xsrc packages will leave old .pc files around.
100: Best to clean out the xsrc objdir entirely before rebuilds.
101:
1.242 christos 102: 20130301:
103: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 104: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 105:
1.238 dholland 106: 20120726:
1.241 wiz 107: The update of OpenSSL requires cleaning both the OpenSSL build
108: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 109: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 110: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 111: cause third-party software to link incorrectly and/or crash.
1.238 dholland 112:
1.237 wiz 113: 20120507:
1.241 wiz 114: The database schema for makemandb was changed. You will
1.237 wiz 115: need to update the database using 'makemandb -f' or wait
116: for the next weekly run to fix it.
117:
1.236 bsh 118: 20120319:
119: sys/conf/Makefile.kern.inc has been modified to adjust the
120: size of db_symtab automatically. You need to update dbsym in
121: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
122: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
123: mk.conf.
124:
1.235 joerg 125: 20120216:
1.241 wiz 126: Default for MKCATPAGES changed to NO. Update builds will fail
127: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 128: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 129: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 130: the next run of weekly will fix it.
1.233 joerg 131:
1.232 christos 132: 20111227:
133: If you built between 20111225 and 20111227 you need to remove
134: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
135: bump has been reverted.
136:
1.231 tls 137: 20111125:
138: The "rnd" pseudodevice has been added to sys/conf/std, which
139: means it should no longer be explicitly listed in kernel
140: configuration files. The line "pseudo-device rnd" should be
141: removed from any custom kernel config files users may have.
142:
1.230 tls 143: 20111119:
144: A problem with the datastructures used by the rndctl(8)
145: utility (pointers in datastructures in an array, making 32->64
146: bit compatibility very painful) has been fixed in a
147: non-backwards-compatible way. If you replace your kernel,
148: replace your rndctl executable too.
1.241 wiz 149:
1.229 jym 150: 20111001:
151: the prop_*_send_syscall() functions from proplib(3) have been
152: changed and their new version is not backward compatible with the old
1.241 wiz 153: one. So ensure that all consumers of these functions (currently:
1.229 jym 154: quota2 code and its tests) are updated together with the new lib.
155:
1.228 mrg 156: 20110817:
157: sparc has been changed to use GCC 4.5.3, so any objdir or
158: DESTDIR for them should be deleted before updating.
159:
1.227 riastrad 160: 20110806:
161: i386 and amd64 have been changed to use GCC 4.5.3, so any
162: objdir or DESTDIR for them should be deleted before updating.
163:
1.226 mrg 164: 20110805:
165: The update to GCC 4.5.3 requires a non-trivial portion of
166: the tree to be cleaned. Best to delete both objdir and
167: DESTDIR before running this update. So far, only the
168: sparc64, mips and powerpc platforms have changed.
169:
1.225 matt 170: 20110803:
1.241 wiz 171: The layout of external/public-domain/xz has changed. To do an
1.225 matt 172: update build you will have to remove the contents of the OBJDIR
173: for external/public-domain/xz/bin by hand as the xz entry there
174: is now a directory.
175:
1.223 joerg 176: 20110410:
1.241 wiz 177: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 178: update build you have to clean both tools/binutils and
179: tools/gcc by hand.
1.223 joerg 180:
1.222 plunky 181: 20110328:
182: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 183: ordering issues with "make all". It may be necessary to remove
1.222 plunky 184: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
185: if your update build fails, as the "Xorg" entry there is now a
186: directory.
187:
1.220 joerg 188: 20110121:
1.221 lukem 189: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 190: the build of individual parts of the tree. This is handled
191: correctly by build.sh. Manual builds have to update /usr/share/mk
192: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 193:
1.217 jruoho 194: 20101217:
195: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 196: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 197: group(5) in order to make the program work with existing setups.
198:
1.216 christos 199: 20101125:
200: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 201: variables with names that contain '='. Revision 1.18 of env.c
202: assumed that this was allowed. Installing a new libc with an
1.216 christos 203: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
204: break which affects the autoconf tests for dependency finding,
205: so building gcc will end up printing:
206: checking dependency style of gcc... none
207: configure: error: no usable dependency style found
208: Fix it by rebuilding and re-installing env.
1.138 lukem 209:
1.215 mrg 210: 20101119:
211: Recent Xorg updates in xsrc/external/mit/ may cause various build
212: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
213: have any build problems with xsrc, or problems with mismatched
214: versions between xorg-server and drivers.
215:
1.213 jmmv 216: 20100604:
217: The update of ATF to 0.9 causes old tests written in shell to fail
218: unless they are rebuilt. If you are building with MKUPDATE=yes,
219: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
220: trees by hand.
221:
1.211 tnozaki 222: 20100522:
1.212 mrg 223: Recent Xorg updates in xsrc/external/mit/ will cause various build
224: problems. Delete your entire DESTDIR and OBJDIR if you have any
225: build problems with xsrc.
226:
227: 20100522:
1.211 tnozaki 228: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 229: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 230:
1.210 christos 231: 20100520:
1.241 wiz 232: The location of the xkb compiled descriptions has changed. Please
1.210 christos 233: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
234:
1.209 njoly 235: 20100222:
236: The shared objects file extension has been changed from .so to
237: .pico, in order to avoid conflicts with shared libraries names
238: libXX.so. All now stale regular .so files can be removed from
239: your object directories.
240:
1.208 roy 241: 20100204:
242: The termcap database has been removed from the sources,
243: but has not been marked obsolete so it is not removed
244: from the system when upgrading.
245: As such, you will need to remove them from your object
246: and destination directories.
247:
1.203 dyoung 248: 20091101:
1.205 dholland 249: After updating, it may be necessary to make the 'cleandir'
250: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
251: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
252: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 253:
1.202 mrg 254: 20091001:
1.206 dholland 255: On amd64 you must rebuild tools (to get the new binutils)
256: before building a kernel, or the build fails on cpufunc.S.
257:
258: 20091001:
1.202 mrg 259: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
260: symlink, failing the build. Delete the link, and the subdir
261: it is in, and retry your build.
262:
1.201 dsl 263: 20090718:
264: libc build changed so that strchr() provides the extra entry
1.241 wiz 265: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 266: may fail because the archive contains the unwanted index.o.
267: (Similarly for strrchr() and rindex().)
268:
1.198 mrg 269: 20090709:
270: Native Xorg was upgraded again. Builds will probably fail again
271: without a clean objdir, at least for src/external/mit/xorg.
272:
1.197 mrg 273: 20090616:
274: Native Xorg was upgraded. Builds will need a clean objdir for
275: src/external/mit/xorg. Upgrading a system from sets will not
276: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
277: subdirectory has been changed into a file, and this needs to
278: be manually "rm -r"'ed before installing xbase.tgz.
279:
1.195 perry 280: 20090501:
281: Several new functions were added to string.h/libc, and this
282: can cause autoconf problems during the tool build for people
1.241 wiz 283: who fail to clean out their tools objects properly. If you
1.195 perry 284: note messages about stpcpy, stpncpy or strnlen accompanying a
285: failure during the tool build, clean out all your tools
286: objects and start again.
287:
1.194 mrg 288: 20090325:
289: The i386 port was switched to i486 default toolchain. This requires
290: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
291:
1.192 skrll 292: 20090126:
1.241 wiz 293: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 294: need to 'rm -f __posix_fadvise50.*' in the libc build directory
295: to avoid using the old assembly stub.
1.192 skrll 296:
1.191 joerg 297: 20090202:
298: pkg_install now depends on the pkgdb cache for automatic conflict
299: detection. It is recommented to rebuild the cache with
300: ``pkg_admin rebuild''.
301:
1.184 christos 302: 20090110:
1.241 wiz 303: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
304: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 305: This is needed even in the MODULAR kernel because there is
306: conditionally compiled code in rtsock.c.
1.184 christos 307: 2. make sure build.sh completes and the binaries in a chroot work
308: before installing.
309: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 310: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 311: are installed properly, and start building libraries first libc
312: and libutil, install them and then continue building all the
1.241 wiz 313: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 314: the new libraries are installed, you can restart the build.
315: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 316: rebuild the required packages to update their shared libraries.
317: Any package you rebuild will require rebuilding all the packages
318: that depend on it.
1.186 christos 319: 5. Next time you run pwd_mkdb with the new binary, the file
320: will be upgraded and it will not be backwards compatible.
1.190 apb 321: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
322: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 323: for utmp. You are better off removing the old files after
1.190 apb 324: upgrading. The automated clearing of /var/run during
325: boot, and the automated rotating of files in /var/log by
326: newsyslog(8), may mean that you do not have to remove the
327: files manually.
328: 7. The optional accounting file (/var/account/acct, see
329: accton(8)) has not been versioned, and will need to be
330: removed. The automatic rotation of the accounting file by
331: /etc/daily limits the bad consequences of failure to remove
332: the file.
1.196 dholland 333: 8. Application software that writes time_t to binary files on
1.241 wiz 334: disk will break or need attention. Most notably: if you are
1.196 dholland 335: using PostgreSQL < 8.4, you need to dump your databases,
336: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 337:
1.183 pgoyette 338: 20081219:
339: config(1) has been updated, and one of the files it creates -
340: swapnetbsd.o - has changed format. You need to rebuild config
341: (done automatically by build.sh) and then you need to rerun
342: config on all kernel configuration files before rebuilding those
343: kernels.
344:
1.181 cube 345: 20081205:
346: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
347: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
348: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 349:
1.179 tsutsui 350: 20081122:
1.182 tsutsui 351: On i386, various kernel options(4) in GENERIC including
1.180 wiz 352: file systems have been disabled and moved into kernel modules.
353: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 354: following files as well as a new GENERIC kernel:
355:
356: - build and install kernel modules from src/sys/modules
357:
358: - install the latest bootloader, which will load a module
1.180 wiz 359: for the file system from which the kernel is loaded automatically
1.179 tsutsui 360:
1.180 wiz 361: If you have to load your kernel from a file system which is not of
362: the same type as the root file system, you have to load the necessary
363: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 364:
1.178 lukem 365: 20080827:
366: If you built and installed a libc from sources between
367: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
368: which results in false errors reported by lint(1).
369: Since this breaks the libc build itself, manual help is
1.180 wiz 370: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 371: $ (cd lib/libc && make MKLINT=no dependall install)
372:
1.177 christos 373: 20080813:
374: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 375: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 376:
1.200 dholland 377: 20080802:
378: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 379: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 380: for -current.
381:
382: Threaded programs (using libpthread) and C++ programs (using
383: libstdc++) compiled after 20070907 and before 20080802 need to
384: be recompiled.
385:
386: One way to find affected pkgsrc packages:
387:
388: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
389: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
390:
1.175 simonb 391: 20080731:
392: WAPBL (metadata journaling support) has been added, but at this
393: time isn't backwards compatible with pre-WAPBL aware kernels
394: and userland (fsck_ffs in particular). Please make sure you
395: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 396: especially an uncleanly mounted journaled filesystem. WAPBL
397: also requires the super block to be in the UFS2 format. You

1.241 wiz 476: root. One side effect is that absolute symlinks inside the emulated

1.1 abs 552: Hints for a more successful build:
553: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 554: Use build.sh, but do not use its "expert mode":
1.132 jmmv 555: This will automatically build the tools in the
1.123 jmc 556: correct order, and it will keep the tools and the
557: new build products from interfering with the running
558: system. This will allow you to ignore most of the
559: other advice in this file.
1.2 mrg 560: Build a new kernel first:
561: This makes sure that any new system calls or features
562: expected by the new userland will be present. This
563: helps to avoid critical errors when upgrading.
1.1 abs 564: Use object directories:
565: This helps to keep stale object
566: files from polluting the build if a Makefile "forgets"
567: about one. It also makes it easier to clean up after
568: a build. It's also necessary if you want to use the
569: same source tree for multiple machines.
1.123 jmc 570: To use object directories with build.sh:
571: a) invoke build.sh with the "-M" or "-O" options.
572: To use object directories without using build.sh:
1.1 abs 573: a) cd /usr/src ; make cleandir
1.2 mrg 574: b) Add "OBJMACHINE=yes" to /etc/mk.conf
575: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 576: d) cd /usr/src ; make build
1.2 mrg 577: Note that running "make obj" in a directory will create
578: in obj.$MACHINE directory.
1.1 abs 579: Build to a DESTDIR:
1.123 jmc 580: This helps to keep old installed files (especially libraries)
581: from interfering with the new build.
582: To build to a DESTDIR with build.sh, use the "-D" option.
583: To build to a DESTDIR without using build.sh, set the DESTDIR
584: environment variable before running make build. It should be
585: set to the pathname of an initially empty directory.
586: Problems: if you do not use build.sh, you might need to
587: update critical utilities without using DESTDIR since
588: nothing is executed from what is installed in DESTDIR.
589: (See critical utils, below.)
1.1 abs 590: Build often:
591: This keeps critical utilities current enough to not choke
592: on any other part of the source tree that depends on up to
1.123 jmc 593: date functionality. If you use build.sh, you should not have
594: this problem.
1.241 wiz 595:
1.1 abs 596: What to do if things don't work:
597: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 598: When things don't work there are usually a few things that commonly
1.1 abs 599: should be done.
600: 1) make includes
601: This should be done automatically by make build.
602: 2) cd share/mk && make install
603: Again, automatically done by make build.
604:
605: Failsafe rebuild of a small part of the tree:
606: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
607: To make sure you rebuild something correctly you want to do
608: something like the following:
609: 1) Make sure the includes and .mk files are up to date.
610: 2) Make sure any program used to build the particular
611: utility is up to date. (yacc, lex, etc...)
612: 3) cd ...path/to/util...
613: make cleandir
614: rm ...all obj directories...
615: make cleandir # yes, again
616: make obj
617: make depend && make
618:
619: Failsafe rebuild of the entire tree:
620: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
621: If you really want to make sure the source tree is clean and
1.2 mrg 622: ready for a build try the following. Note that sourcing /etc/mk.conf
623: (a make(1) Makefile) in this manner is not right, and will not work
