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:
1.262 ! christos 22: 20150413:
! 23: New acpica requires "make cleandir" and reinstalling yacc
! 24: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
! 25: also "make cleandir" in /usr/src/external/bsd/acpica.
! 26:
1.261 martin 27: 20150404:
28: Lint changes require a full rebuild of the tool, so make
29: sure to build without -u option to build.sh, or manually
30: do a make cleandir in src/tools/lint1 and
31: src/usr.bin/xlint.
32:
1.260 skrll 33: 20150310:
34: Improvements to openssl for arm mean that update builds of
35: the openssl libraries will fail. A make cleandir in
36: external/bsd/openssl/lib is needed
37:
1.258 martin 38: 20141026:
1.259 msaitoh 39: A mishap during the import of pppd may cause your corruption
1.258 martin 40: in your cvs directory if you happened to do a cvs update
41: during a short period of time. To fix, just remove the
42: directory src/external/bsd/ppp/dist/pppd completely
43: and let cvs restore it on next update.
44:
1.256 apb 45: 20140721:
46: The src/external/mit/lua/src directory was accidentally created
47: and then deleted in the CVS repository. If you get errors like
48:
49: cvs [update aborted]: cannot open directory
50: /cvsroot/src/external/mit/lua/src: No such file or directory
51:
52: then delete your local copy of that directory tree and try again.
53:
1.255 joerg 54: 20140530:
55: ARM eABI switched to DWARF based exception handling. This requires
56: rebuilding all C++ code. It is strongly advised to do a clean build.
57:
1.251 martin 58: 20140131:
1.253 joerg 59: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 60: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 61: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 62:
1.250 christos 63: 20131227:
64: 1. The new ntpd runs in a restricted mode to prevent amplification
65: attacks. If you need ntpdc to work you need to explicitly enable
66: mode7 in your config file. Make sure you put the necessary restrict
67: statements to avoid being exposed.
68: 2. strncat has moved from lib/libc to common/lib/libc; you might need
69: to make clean in libc
70:
1.249 mrg 71: 20131129:
72: The GMP sources were updated, and builds will likely fail without
73: cleaning their build trees for both tools and in-tree, like below.
74:
1.248 mrg 75: 20131128:
76: The MPC and MPFR sources were updated, and builds may require their
77: tools and in-tree directories cleaned for successful updates.
78:
1.246 martin 79: 20130605:
1.247 spz 80: The kernel option FAST_IPSEC no longer exists, it's been renamed
81: to IPSEC (and the older IPSEC version removed).
82:
83: 20130605:
1.246 martin 84: Previous freetype installations eroneously installed private
85: header files. If you are building against a non-empty $DESTDIR,
86: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
87:
1.245 mrg 88: 20130531:
89: The xdm update may cause build failure due to xdm.man being
90: in the obj tree. Make sure to ensure any like this:
91: nbmake: nbmake: don't know how to make xdm.man. Stop
92: is fixed by deleting the xdm.man in the obj tree.
93:
1.244 mrg 94: 20130530:
95: Updates of many xsrc packages will leave old .pc files around.
96: Best to clean out the xsrc objdir entirely before rebuilds.
97:
1.242 christos 98: 20130301:
99: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 100: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 101:
1.238 dholland 102: 20120726:
1.241 wiz 103: The update of OpenSSL requires cleaning both the OpenSSL build
104: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 105: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 106: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 107: cause third-party software to link incorrectly and/or crash.
1.238 dholland 108:
1.237 wiz 109: 20120507:
1.241 wiz 110: The database schema for makemandb was changed. You will
1.237 wiz 111: need to update the database using 'makemandb -f' or wait
112: for the next weekly run to fix it.
113:
1.236 bsh 114: 20120319:
115: sys/conf/Makefile.kern.inc has been modified to adjust the
116: size of db_symtab automatically. You need to update dbsym in
117: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
118: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
119: mk.conf.
120:
1.235 joerg 121: 20120216:
1.241 wiz 122: Default for MKCATPAGES changed to NO. Update builds will fail
123: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 124: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 125: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 126: the next run of weekly will fix it.
1.233 joerg 127:
1.232 christos 128: 20111227:
129: If you built between 20111225 and 20111227 you need to remove
130: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
131: bump has been reverted.
132:
1.231 tls 133: 20111125:
134: The "rnd" pseudodevice has been added to sys/conf/std, which
135: means it should no longer be explicitly listed in kernel
136: configuration files. The line "pseudo-device rnd" should be
137: removed from any custom kernel config files users may have.
138:
1.230 tls 139: 20111119:
140: A problem with the datastructures used by the rndctl(8)
141: utility (pointers in datastructures in an array, making 32->64
142: bit compatibility very painful) has been fixed in a
143: non-backwards-compatible way. If you replace your kernel,
144: replace your rndctl executable too.
1.241 wiz 145:
1.229 jym 146: 20111001:
147: the prop_*_send_syscall() functions from proplib(3) have been
148: changed and their new version is not backward compatible with the old
1.241 wiz 149: one. So ensure that all consumers of these functions (currently:
1.229 jym 150: quota2 code and its tests) are updated together with the new lib.
151:
1.228 mrg 152: 20110817:
153: sparc has been changed to use GCC 4.5.3, so any objdir or
154: DESTDIR for them should be deleted before updating.
155:
1.227 riastrad 156: 20110806:
157: i386 and amd64 have been changed to use GCC 4.5.3, so any
158: objdir or DESTDIR for them should be deleted before updating.
159:
1.226 mrg 160: 20110805:
161: The update to GCC 4.5.3 requires a non-trivial portion of
162: the tree to be cleaned. Best to delete both objdir and
163: DESTDIR before running this update. So far, only the
164: sparc64, mips and powerpc platforms have changed.
165:
1.225 matt 166: 20110803:
1.241 wiz 167: The layout of external/public-domain/xz has changed. To do an
1.225 matt 168: update build you will have to remove the contents of the OBJDIR
169: for external/public-domain/xz/bin by hand as the xz entry there
170: is now a directory.
171:
1.223 joerg 172: 20110410:
1.241 wiz 173: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 174: update build you have to clean both tools/binutils and
175: tools/gcc by hand.
1.223 joerg 176:
1.222 plunky 177: 20110328:
178: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 179: ordering issues with "make all". It may be necessary to remove
1.222 plunky 180: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
181: if your update build fails, as the "Xorg" entry there is now a
182: directory.
183:
1.220 joerg 184: 20110121:
1.221 lukem 185: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 186: the build of individual parts of the tree. This is handled
187: correctly by build.sh. Manual builds have to update /usr/share/mk
188: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 189:
1.217 jruoho 190: 20101217:
191: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 192: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 193: group(5) in order to make the program work with existing setups.
194:
1.216 christos 195: 20101125:
196: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 197: variables with names that contain '='. Revision 1.18 of env.c
198: assumed that this was allowed. Installing a new libc with an
1.216 christos 199: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
200: break which affects the autoconf tests for dependency finding,
201: so building gcc will end up printing:
202: checking dependency style of gcc... none
203: configure: error: no usable dependency style found
204: Fix it by rebuilding and re-installing env.
1.138 lukem 205:
1.215 mrg 206: 20101119:
207: Recent Xorg updates in xsrc/external/mit/ may cause various build
208: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
209: have any build problems with xsrc, or problems with mismatched
210: versions between xorg-server and drivers.
211:
1.213 jmmv 212: 20100604:
213: The update of ATF to 0.9 causes old tests written in shell to fail
214: unless they are rebuilt. If you are building with MKUPDATE=yes,
215: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
216: trees by hand.
217:
1.211 tnozaki 218: 20100522:
1.212 mrg 219: Recent Xorg updates in xsrc/external/mit/ will cause various build
220: problems. Delete your entire DESTDIR and OBJDIR if you have any
221: build problems with xsrc.
222:
223: 20100522:
1.211 tnozaki 224: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 225: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 226:
1.210 christos 227: 20100520:
1.241 wiz 228: The location of the xkb compiled descriptions has changed. Please
1.210 christos 229: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
230:
1.209 njoly 231: 20100222:
232: The shared objects file extension has been changed from .so to
233: .pico, in order to avoid conflicts with shared libraries names
234: libXX.so. All now stale regular .so files can be removed from
235: your object directories.
236:
1.208 roy 237: 20100204:
238: The termcap database has been removed from the sources,
239: but has not been marked obsolete so it is not removed
240: from the system when upgrading.
241: As such, you will need to remove them from your object
242: and destination directories.
243:
1.203 dyoung 244: 20091101:
1.205 dholland 245: After updating, it may be necessary to make the 'cleandir'
246: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
247: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
248: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 249:
1.202 mrg 250: 20091001:
1.206 dholland 251: On amd64 you must rebuild tools (to get the new binutils)
252: before building a kernel, or the build fails on cpufunc.S.
253:
254: 20091001:
1.202 mrg 255: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
256: symlink, failing the build. Delete the link, and the subdir
257: it is in, and retry your build.
258:
1.201 dsl 259: 20090718:
260: libc build changed so that strchr() provides the extra entry
1.241 wiz 261: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 262: may fail because the archive contains the unwanted index.o.
263: (Similarly for strrchr() and rindex().)
264:
1.198 mrg 265: 20090709:
266: Native Xorg was upgraded again. Builds will probably fail again
267: without a clean objdir, at least for src/external/mit/xorg.
268:
1.197 mrg 269: 20090616:
270: Native Xorg was upgraded. Builds will need a clean objdir for
271: src/external/mit/xorg. Upgrading a system from sets will not
272: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
273: subdirectory has been changed into a file, and this needs to
274: be manually "rm -r"'ed before installing xbase.tgz.
275:
1.195 perry 276: 20090501:
277: Several new functions were added to string.h/libc, and this
278: can cause autoconf problems during the tool build for people
1.241 wiz 279: who fail to clean out their tools objects properly. If you
1.195 perry 280: note messages about stpcpy, stpncpy or strnlen accompanying a
281: failure during the tool build, clean out all your tools
282: objects and start again.
283:
1.194 mrg 284: 20090325:
285: The i386 port was switched to i486 default toolchain. This requires
286: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
287:
1.192 skrll 288: 20090126:
1.241 wiz 289: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 290: need to 'rm -f __posix_fadvise50.*' in the libc build directory
291: to avoid using the old assembly stub.
1.192 skrll 292:
1.191 joerg 293: 20090202:
294: pkg_install now depends on the pkgdb cache for automatic conflict
295: detection. It is recommented to rebuild the cache with
296: ``pkg_admin rebuild''.
297:
1.184 christos 298: 20090110:
1.241 wiz 299: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
300: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 301: This is needed even in the MODULAR kernel because there is
302: conditionally compiled code in rtsock.c.
1.184 christos 303: 2. make sure build.sh completes and the binaries in a chroot work
304: before installing.
305: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 306: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 307: are installed properly, and start building libraries first libc
308: and libutil, install them and then continue building all the
1.241 wiz 309: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 310: the new libraries are installed, you can restart the build.
311: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 312: rebuild the required packages to update their shared libraries.
313: Any package you rebuild will require rebuilding all the packages
314: that depend on it.
1.186 christos 315: 5. Next time you run pwd_mkdb with the new binary, the file
316: will be upgraded and it will not be backwards compatible.
1.190 apb 317: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
318: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 319: for utmp. You are better off removing the old files after
1.190 apb 320: upgrading. The automated clearing of /var/run during
321: boot, and the automated rotating of files in /var/log by
322: newsyslog(8), may mean that you do not have to remove the
323: files manually.
324: 7. The optional accounting file (/var/account/acct, see
325: accton(8)) has not been versioned, and will need to be
326: removed. The automatic rotation of the accounting file by
327: /etc/daily limits the bad consequences of failure to remove
328: the file.
1.196 dholland 329: 8. Application software that writes time_t to binary files on
1.241 wiz 330: disk will break or need attention. Most notably: if you are
1.196 dholland 331: using PostgreSQL < 8.4, you need to dump your databases,
332: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 333:
1.183 pgoyette 334: 20081219:
335: config(1) has been updated, and one of the files it creates -
336: swapnetbsd.o - has changed format. You need to rebuild config
337: (done automatically by build.sh) and then you need to rerun
338: config on all kernel configuration files before rebuilding those
339: kernels.
340:
1.181 cube 341: 20081205:
342: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
343: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
344: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 345:
1.179 tsutsui 346: 20081122:
1.182 tsutsui 347: On i386, various kernel options(4) in GENERIC including
1.180 wiz 348: file systems have been disabled and moved into kernel modules.
349: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 350: following files as well as a new GENERIC kernel:
351:
352: - build and install kernel modules from src/sys/modules
353:
354: - install the latest bootloader, which will load a module
1.180 wiz 355: for the file system from which the kernel is loaded automatically
1.179 tsutsui 356:
1.180 wiz 357: If you have to load your kernel from a file system which is not of
358: the same type as the root file system, you have to load the necessary
359: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 360:
1.178 lukem 361: 20080827:
362: If you built and installed a libc from sources between
363: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
364: which results in false errors reported by lint(1).
365: Since this breaks the libc build itself, manual help is
1.180 wiz 366: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 367: $ (cd lib/libc && make MKLINT=no dependall install)
368:
1.177 christos 369: 20080813:
370: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 371: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 372:
1.200 dholland 373: 20080802:
374: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 375: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 376: for -current.
377:
378: Threaded programs (using libpthread) and C++ programs (using
379: libstdc++) compiled after 20070907 and before 20080802 need to
380: be recompiled.
381:
382: One way to find affected pkgsrc packages:
383:
384: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
385: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
386:
1.175 simonb 387: 20080731:
388: WAPBL (metadata journaling support) has been added, but at this
389: time isn't backwards compatible with pre-WAPBL aware kernels
390: and userland (fsck_ffs in particular). Please make sure you
391: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 392: especially an uncleanly mounted journaled filesystem. WAPBL
393: also requires the super block to be in the UFS2 format. You
394: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 395:
1.174 lukem 396: 20080721:
397: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR

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

470: has been changed. Rather than modify the pathname (and copy back
471: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 472: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 473: root file system will be relative to that file system - unless they
1.161 dsl 474: start /../ this is useful when the emulated root is a real install

500: The threading model was changed when the newlock2 branch
501: was merged to NetBSD-current. If you boot with a new
502: kernel (version 4.99.10), then you also need a new pthread
503: library (/usr/lib/libpthread.so.0.7). If you boot with

1.1 abs 548: Hints for a more successful build:
549: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 550: Use build.sh, but do not use its "expert mode":
1.132 jmmv 551: This will automatically build the tools in the
1.123 jmc 552: correct order, and it will keep the tools and the
553: new build products from interfering with the running
554: system. This will allow you to ignore most of the
555: other advice in this file.
1.2 mrg 556: Build a new kernel first:
557: This makes sure that any new system calls or features
558: expected by the new userland will be present. This
559: helps to avoid critical errors when upgrading.
1.1 abs 560: Use object directories:
561: This helps to keep stale object
562: files from polluting the build if a Makefile "forgets"
563: about one. It also makes it easier to clean up after
564: a build. It's also necessary if you want to use the
565: same source tree for multiple machines.
1.123 jmc 566: To use object directories with build.sh:
567: a) invoke build.sh with the "-M" or "-O" options.
568: To use object directories without using build.sh:
1.1 abs 569: a) cd /usr/src ; make cleandir
1.2 mrg 570: b) Add "OBJMACHINE=yes" to /etc/mk.conf
571: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 572: d) cd /usr/src ; make build
1.2 mrg 573: Note that running "make obj" in a directory will create
574: in obj.$MACHINE directory.
1.1 abs 575: Build to a DESTDIR:
1.123 jmc 576: This helps to keep old installed files (especially libraries)
577: from interfering with the new build.
578: To build to a DESTDIR with build.sh, use the "-D" option.
579: To build to a DESTDIR without using build.sh, set the DESTDIR
580: environment variable before running make build. It should be
581: set to the pathname of an initially empty directory.
582: Problems: if you do not use build.sh, you might need to
583: update critical utilities without using DESTDIR since
584: nothing is executed from what is installed in DESTDIR.
585: (See critical utils, below.)
1.1 abs 586: Build often:
587: This keeps critical utilities current enough to not choke
588: on any other part of the source tree that depends on up to
1.123 jmc 589: date functionality. If you use build.sh, you should not have
590: this problem.
1.241 wiz 591:
1.1 abs 592: What to do if things don't work:
593: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 594: When things don't work there are usually a few things that commonly
1.1 abs 595: should be done.
596: 1) make includes
597: This should be done automatically by make build.
598: 2) cd share/mk && make install
599: Again, automatically done by make build.
600:
601: Failsafe rebuild of a small part of the tree:
602: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
603: To make sure you rebuild something correctly you want to do
604: something like the following:
605: 1) Make sure the includes and .mk files are up to date.
606: 2) Make sure any program used to build the particular
607: utility is up to date. (yacc, lex, etc...)
608: 3) cd ...path/to/util...
609: make cleandir
610: rm ...all obj directories...
611: make cleandir # yes, again
612: make obj
613: make depend && make
614:
615: Failsafe rebuild of the entire tree:
616: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
617: If you really want to make sure the source tree is clean and
1.2 mrg 618: ready for a build try the following. Note that sourcing /etc/mk.conf
619: (a make(1) Makefile) in this manner is not right, and will not work
