1.257 ! apb 1: $NetBSD: UPDATING,v 1.256 2014/07/23 08:37:03 apb Exp $
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:
1.256 apb 22: 20140721:
23: The src/external/mit/lua/src directory was accidentally created
24: and then deleted in the CVS repository. If you get errors like
25:
26: cvs [update aborted]: cannot open directory
27: /cvsroot/src/external/mit/lua/src: No such file or directory
28:
29: then delete your local copy of that directory tree and try again.
30:
1.255 joerg 31: 20140530:
32: ARM eABI switched to DWARF based exception handling. This requires
33: rebuilding all C++ code. It is strongly advised to do a clean build.
34:
1.251 martin 35: 20140131:
1.253 joerg 36: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 37: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 38: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 39:
1.250 christos 40: 20131227:
41: 1. The new ntpd runs in a restricted mode to prevent amplification
42: attacks. If you need ntpdc to work you need to explicitly enable
43: mode7 in your config file. Make sure you put the necessary restrict
44: statements to avoid being exposed.
45: 2. strncat has moved from lib/libc to common/lib/libc; you might need
46: to make clean in libc
47:
1.249 mrg 48: 20131129:
49: The GMP sources were updated, and builds will likely fail without
50: cleaning their build trees for both tools and in-tree, like below.
51:
1.248 mrg 52: 20131128:
53: The MPC and MPFR sources were updated, and builds may require their
54: tools and in-tree directories cleaned for successful updates.
55:
1.246 martin 56: 20130605:
1.247 spz 57: The kernel option FAST_IPSEC no longer exists, it's been renamed
58: to IPSEC (and the older IPSEC version removed).
59:
60: 20130605:
1.246 martin 61: Previous freetype installations eroneously installed private
62: header files. If you are building against a non-empty $DESTDIR,
63: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
64:
1.245 mrg 65: 20130531:
66: The xdm update may cause build failure due to xdm.man being
67: in the obj tree. Make sure to ensure any like this:
68: nbmake: nbmake: don't know how to make xdm.man. Stop
69: is fixed by deleting the xdm.man in the obj tree.
70:
1.244 mrg 71: 20130530:
72: Updates of many xsrc packages will leave old .pc files around.
73: Best to clean out the xsrc objdir entirely before rebuilds.
74:
1.242 christos 75: 20130301:
76: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 77: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 78:
1.238 dholland 79: 20120726:
1.241 wiz 80: The update of OpenSSL requires cleaning both the OpenSSL build
81: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 82: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 83: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 84: cause third-party software to link incorrectly and/or crash.
1.238 dholland 85:
1.237 wiz 86: 20120507:
1.241 wiz 87: The database schema for makemandb was changed. You will
1.237 wiz 88: need to update the database using 'makemandb -f' or wait
89: for the next weekly run to fix it.
90:
1.236 bsh 91: 20120319:
92: sys/conf/Makefile.kern.inc has been modified to adjust the
93: size of db_symtab automatically. You need to update dbsym in
94: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
95: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
96: mk.conf.
97:
1.235 joerg 98: 20120216:
1.241 wiz 99: Default for MKCATPAGES changed to NO. Update builds will fail
100: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 101: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 102: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 103: the next run of weekly will fix it.
1.233 joerg 104:
1.232 christos 105: 20111227:
106: If you built between 20111225 and 20111227 you need to remove
107: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
108: bump has been reverted.
109:
1.231 tls 110: 20111125:
111: The "rnd" pseudodevice has been added to sys/conf/std, which
112: means it should no longer be explicitly listed in kernel
113: configuration files. The line "pseudo-device rnd" should be
114: removed from any custom kernel config files users may have.
115:
1.230 tls 116: 20111119:
117: A problem with the datastructures used by the rndctl(8)
118: utility (pointers in datastructures in an array, making 32->64
119: bit compatibility very painful) has been fixed in a
120: non-backwards-compatible way. If you replace your kernel,
121: replace your rndctl executable too.
1.241 wiz 122:
1.229 jym 123: 20111001:
124: the prop_*_send_syscall() functions from proplib(3) have been
125: changed and their new version is not backward compatible with the old
1.241 wiz 126: one. So ensure that all consumers of these functions (currently:
1.229 jym 127: quota2 code and its tests) are updated together with the new lib.
128:
1.228 mrg 129: 20110817:
130: sparc has been changed to use GCC 4.5.3, so any objdir or
131: DESTDIR for them should be deleted before updating.
132:
1.227 riastrad 133: 20110806:
134: i386 and amd64 have been changed to use GCC 4.5.3, so any
135: objdir or DESTDIR for them should be deleted before updating.
136:
1.226 mrg 137: 20110805:
138: The update to GCC 4.5.3 requires a non-trivial portion of
139: the tree to be cleaned. Best to delete both objdir and
140: DESTDIR before running this update. So far, only the
141: sparc64, mips and powerpc platforms have changed.
142:
1.225 matt 143: 20110803:
1.241 wiz 144: The layout of external/public-domain/xz has changed. To do an
1.225 matt 145: update build you will have to remove the contents of the OBJDIR
146: for external/public-domain/xz/bin by hand as the xz entry there
147: is now a directory.
148:
1.223 joerg 149: 20110410:
1.241 wiz 150: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 151: update build you have to clean both tools/binutils and
152: tools/gcc by hand.
1.223 joerg 153:
1.222 plunky 154: 20110328:
155: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 156: ordering issues with "make all". It may be necessary to remove
1.222 plunky 157: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
158: if your update build fails, as the "Xorg" entry there is now a
159: directory.
160:
1.220 joerg 161: 20110121:
1.221 lukem 162: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 163: the build of individual parts of the tree. This is handled
164: correctly by build.sh. Manual builds have to update /usr/share/mk
165: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 166:
1.217 jruoho 167: 20101217:
168: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 169: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 170: group(5) in order to make the program work with existing setups.
171:
1.216 christos 172: 20101125:
173: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 174: variables with names that contain '='. Revision 1.18 of env.c
175: assumed that this was allowed. Installing a new libc with an
1.216 christos 176: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
177: break which affects the autoconf tests for dependency finding,
178: so building gcc will end up printing:
179: checking dependency style of gcc... none
180: configure: error: no usable dependency style found
181: Fix it by rebuilding and re-installing env.
1.138 lukem 182:
1.215 mrg 183: 20101119:
184: Recent Xorg updates in xsrc/external/mit/ may cause various build
185: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
186: have any build problems with xsrc, or problems with mismatched
187: versions between xorg-server and drivers.
188:
1.213 jmmv 189: 20100604:
190: The update of ATF to 0.9 causes old tests written in shell to fail
191: unless they are rebuilt. If you are building with MKUPDATE=yes,
192: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
193: trees by hand.
194:
1.211 tnozaki 195: 20100522:
1.212 mrg 196: Recent Xorg updates in xsrc/external/mit/ will cause various build
197: problems. Delete your entire DESTDIR and OBJDIR if you have any
198: build problems with xsrc.
199:
200: 20100522:
1.211 tnozaki 201: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 202: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 203:
1.210 christos 204: 20100520:
1.241 wiz 205: The location of the xkb compiled descriptions has changed. Please
1.210 christos 206: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
207:
1.209 njoly 208: 20100222:
209: The shared objects file extension has been changed from .so to
210: .pico, in order to avoid conflicts with shared libraries names
211: libXX.so. All now stale regular .so files can be removed from
212: your object directories.
213:
1.208 roy 214: 20100204:
215: The termcap database has been removed from the sources,
216: but has not been marked obsolete so it is not removed
217: from the system when upgrading.
218: As such, you will need to remove them from your object
219: and destination directories.
220:
1.203 dyoung 221: 20091101:
1.205 dholland 222: After updating, it may be necessary to make the 'cleandir'
223: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
224: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
225: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 226:
1.202 mrg 227: 20091001:
1.206 dholland 228: On amd64 you must rebuild tools (to get the new binutils)
229: before building a kernel, or the build fails on cpufunc.S.
230:
231: 20091001:
1.202 mrg 232: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
233: symlink, failing the build. Delete the link, and the subdir
234: it is in, and retry your build.
235:
1.201 dsl 236: 20090718:
237: libc build changed so that strchr() provides the extra entry
1.241 wiz 238: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 239: may fail because the archive contains the unwanted index.o.
240: (Similarly for strrchr() and rindex().)
241:
1.198 mrg 242: 20090709:
243: Native Xorg was upgraded again. Builds will probably fail again
244: without a clean objdir, at least for src/external/mit/xorg.
245:
1.197 mrg 246: 20090616:
247: Native Xorg was upgraded. Builds will need a clean objdir for
248: src/external/mit/xorg. Upgrading a system from sets will not
249: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
250: subdirectory has been changed into a file, and this needs to
251: be manually "rm -r"'ed before installing xbase.tgz.
252:
1.195 perry 253: 20090501:
254: Several new functions were added to string.h/libc, and this
255: can cause autoconf problems during the tool build for people
1.241 wiz 256: who fail to clean out their tools objects properly. If you
1.195 perry 257: note messages about stpcpy, stpncpy or strnlen accompanying a
258: failure during the tool build, clean out all your tools
259: objects and start again.
260:
1.194 mrg 261: 20090325:
262: The i386 port was switched to i486 default toolchain. This requires
263: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
264:
1.192 skrll 265: 20090126:
1.241 wiz 266: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 267: need to 'rm -f __posix_fadvise50.*' in the libc build directory
268: to avoid using the old assembly stub.
1.192 skrll 269:
1.191 joerg 270: 20090202:
271: pkg_install now depends on the pkgdb cache for automatic conflict
272: detection. It is recommented to rebuild the cache with
273: ``pkg_admin rebuild''.
274:
1.184 christos 275: 20090110:
1.241 wiz 276: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
277: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 278: This is needed even in the MODULAR kernel because there is
279: conditionally compiled code in rtsock.c.
1.184 christos 280: 2. make sure build.sh completes and the binaries in a chroot work
281: before installing.
282: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 283: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 284: are installed properly, and start building libraries first libc
285: and libutil, install them and then continue building all the
1.241 wiz 286: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 287: the new libraries are installed, you can restart the build.
288: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 289: rebuild the required packages to update their shared libraries.
290: Any package you rebuild will require rebuilding all the packages
291: that depend on it.
1.186 christos 292: 5. Next time you run pwd_mkdb with the new binary, the file
293: will be upgraded and it will not be backwards compatible.
1.190 apb 294: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
295: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 296: for utmp. You are better off removing the old files after
1.190 apb 297: upgrading. The automated clearing of /var/run during
298: boot, and the automated rotating of files in /var/log by
299: newsyslog(8), may mean that you do not have to remove the
300: files manually.
301: 7. The optional accounting file (/var/account/acct, see
302: accton(8)) has not been versioned, and will need to be
303: removed. The automatic rotation of the accounting file by
304: /etc/daily limits the bad consequences of failure to remove
305: the file.
1.196 dholland 306: 8. Application software that writes time_t to binary files on
1.241 wiz 307: disk will break or need attention. Most notably: if you are
1.196 dholland 308: using PostgreSQL < 8.4, you need to dump your databases,
309: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 310:
1.183 pgoyette 311: 20081219:
312: config(1) has been updated, and one of the files it creates -
313: swapnetbsd.o - has changed format. You need to rebuild config
314: (done automatically by build.sh) and then you need to rerun
315: config on all kernel configuration files before rebuilding those
316: kernels.
317:
1.181 cube 318: 20081205:
319: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
320: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
321: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 322:
1.179 tsutsui 323: 20081122:
1.182 tsutsui 324: On i386, various kernel options(4) in GENERIC including
1.180 wiz 325: file systems have been disabled and moved into kernel modules.
326: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 327: following files as well as a new GENERIC kernel:
328:
329: - build and install kernel modules from src/sys/modules
330:
331: - install the latest bootloader, which will load a module
1.180 wiz 332: for the file system from which the kernel is loaded automatically
1.179 tsutsui 333:
1.180 wiz 334: If you have to load your kernel from a file system which is not of
335: the same type as the root file system, you have to load the necessary
336: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 337:
1.178 lukem 338: 20080827:
339: If you built and installed a libc from sources between
340: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
341: which results in false errors reported by lint(1).
342: Since this breaks the libc build itself, manual help is
1.180 wiz 343: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 344: $ (cd lib/libc && make MKLINT=no dependall install)
345:
1.177 christos 346: 20080813:
347: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 348: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 349:
1.200 dholland 350: 20080802:
351: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 352: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 353: for -current.
354:
355: Threaded programs (using libpthread) and C++ programs (using
356: libstdc++) compiled after 20070907 and before 20080802 need to
357: be recompiled.
358:
359: One way to find affected pkgsrc packages:
360:
361: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
362: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
363:
1.175 simonb 364: 20080731:
365: WAPBL (metadata journaling support) has been added, but at this
366: time isn't backwards compatible with pre-WAPBL aware kernels
367: and userland (fsck_ffs in particular). Please make sure you
368: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 369: especially an uncleanly mounted journaled filesystem. WAPBL
370: also requires the super block to be in the UFS2 format. You
371: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 372:
1.174 lukem 373: 20080721:
374: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
375: isn't defined.
376:
1.173 freza 377: 20080531:
1.241 wiz 378: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
379: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 380: utility needs to be rebuilt and reinstalled as older binaries
1.241 wiz 381: won't work correctly. The following sequence of commands:
1.173 freza 382:
383: $ (cd sys/sys/ && nbmake-$arch includes)
384: $ (cd sbin/drvctl/ && nbmake-$arch clean)
385: $ (cd sbin/drvctl/ && nbmake-$arch all)
386:
387: leaves new drvctl utility in sbin/drvctl build directory.
388:
1.172 lukem 389: 20080503:
390: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
391:
1.171 he 392: 20080521:
393: For a while, unprivileged UPDATE builds would fail to

1.1 abs 525: Hints for a more successful build:
526: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 527: Use build.sh, but do not use its "expert mode":
1.132 jmmv 528: This will automatically build the tools in the
1.123 jmc 529: correct order, and it will keep the tools and the
530: new build products from interfering with the running
531: system. This will allow you to ignore most of the
532: other advice in this file.
1.2 mrg 533: Build a new kernel first:
534: This makes sure that any new system calls or features
535: expected by the new userland will be present. This
536: helps to avoid critical errors when upgrading.
1.1 abs 537: Use object directories:
538: This helps to keep stale object
539: files from polluting the build if a Makefile "forgets"
540: about one. It also makes it easier to clean up after
541: a build. It's also necessary if you want to use the
542: same source tree for multiple machines.
1.123 jmc 543: To use object directories with build.sh:
544: a) invoke build.sh with the "-M" or "-O" options.
545: To use object directories without using build.sh:
1.1 abs 546: a) cd /usr/src ; make cleandir
1.2 mrg 547: b) Add "OBJMACHINE=yes" to /etc/mk.conf
548: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 549: d) cd /usr/src ; make build
1.2 mrg 550: Note that running "make obj" in a directory will create
551: in obj.$MACHINE directory.
1.1 abs 552: Build to a DESTDIR:
1.123 jmc 553: This helps to keep old installed files (especially libraries)
554: from interfering with the new build.
555: To build to a DESTDIR with build.sh, use the "-D" option.
556: To build to a DESTDIR without using build.sh, set the DESTDIR
557: environment variable before running make build. It should be
558: set to the pathname of an initially empty directory.
559: Problems: if you do not use build.sh, you might need to
560: update critical utilities without using DESTDIR since
561: nothing is executed from what is installed in DESTDIR.
562: (See critical utils, below.)
1.1 abs 563: Build often:
564: This keeps critical utilities current enough to not choke
565: on any other part of the source tree that depends on up to
1.123 jmc 566: date functionality. If you use build.sh, you should not have
567: this problem.

570: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 571: When things don't work there are usually a few things that commonly
1.1 abs 572: should be done.
573: 1) make includes

575: 2) cd share/mk && make install
576: Again, automatically done by make build.
577:
578: Failsafe rebuild of a small part of the tree:
579: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
580: To make sure you rebuild something correctly you want to do
581: something like the following:
582: 1) Make sure the includes and .mk files are up to date.
583: 2) Make sure any program used to build the particular
584: utility is up to date. (yacc, lex, etc...)
585: 3) cd ...path/to/util...
586: make cleandir
587: rm ...all obj directories...
588: make cleandir # yes, again
589: make obj
590: make depend && make
591:
592: Failsafe rebuild of the entire tree:
593: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
594: If you really want to make sure the source tree is clean and
1.2 mrg 595: ready for a build try the following. Note that sourcing /etc/mk.conf
