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.

20: ^^^^^^^^^^^^^^^
1.230 tls 21:
1.276 ! martin 22: 20170103:
! 23: a new version of flex has been imported.
! 24: Remove the file from obj (external/bsd/flex)
! 25: if you build.sh -u
! 26:
1.275 spz 27: 20161014:
28: a new version of OpenSSL has been imported.
29: Remove the files from obj (crypto/external/bsd/openssl)
30: if you build.sh -u
31:
1.274 martin 32: 20161009:
33: a new version of dhcpcd has been imported with slightly changed
34: build infrastructure. When doing a build.sh -u this requires
35: pruning the external/bsd/dhcpcd objdir.
36:
1.273 mrg 37: 20160914:
38: i386, amd64, shark, ofppc and macppc have joined shark and x68k
39: ports in using xorg-server 1.18. This requires a clean destdir
40: and a clean objdir.
41:
1.272 dholland 42: 20160527:
43: i386 needs a full cleandir or objdir deletion because PIE has
44: been enabled. (see the amd64 entry two down for further info)
45:
1.270 christos 46: 20160418:
47: libedit needs manual removal of all autogenerated files since
1.271 christos 48: some of them are not autogenerated anymore. Remember that there
49: might be two copies of libedit if your platform builds "compat".
1.270 christos 50:
1.268 riastrad 51: 20160410:
52: amd64 needs full "make cleandir" or deletion of objdir now that
53: PIE has been enabled for amd64. PIE, or position-independent
54: executables, means all code, including executables and not just
55: shared libraries, is position-independent and hence able to be
56: relocated by ASLR, address space layout randomization.
57:
58: The change was made in Makefile variables for compiler and
59: linker flags, for which make(1) does not record dependencies,
60: hence it is unable to detect that all .o files need rebuilding.
61:
62: Partial rebuilds with some modified source files will likely
63: fail when linking executables, since the linker refuses to mix
64: position-independent code with position-dependent code in
65: position-independent executables:
66:
67: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
68:
1.267 mrg 69: 20160401:
70: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 71: Some people have found that cleandir is not sufficient, so if
72: in doubt delete the entire object directory tree for gcc.
1.267 mrg 73:
1.266 aymeric 74: 20160306:
1.265 aymeric 75: NetBSD's regexp implementation is now part of libnbcompat.
76: Nblex, nbm4, nbpax, nbsed use it and they may crash on
77: non-NetBSD hosts if linked with stale object files produced
78: while they included a non-NetBSD regex.h.
79: In any case, you should "make cleandir" at least these tools
80: before updating your toolchain.
81:
1.264 martin 82: 20160125:
83: Dtrace has been enabled by default on some architectures.
84: When doing an update build, make sure to clean the etc/mtree
85: object directory before starting the build - otherwise the
86: needed directories in destdir will not be created.
87: An easy way to do this is:
88: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
89:
1.263 dholland 90: 20150818:
91: New acpica requires "make cleandir" in src/external/bsd/acpica
92: again.
93:
1.262 christos 94: 20150413:
95: New acpica requires "make cleandir" and reinstalling yacc
96: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
97: also "make cleandir" in /usr/src/external/bsd/acpica.
98:
1.261 martin 99: 20150404:
100: Lint changes require a full rebuild of the tool, so make
101: sure to build without -u option to build.sh, or manually
102: do a make cleandir in src/tools/lint1 and
103: src/usr.bin/xlint.
104:
1.260 skrll 105: 20150310:
106: Improvements to openssl for arm mean that update builds of
107: the openssl libraries will fail. A make cleandir in
108: external/bsd/openssl/lib is needed
109:
1.258 martin 110: 20141026:
1.259 msaitoh 111: A mishap during the import of pppd may cause your corruption
1.258 martin 112: in your cvs directory if you happened to do a cvs update
113: during a short period of time. To fix, just remove the
114: directory src/external/bsd/ppp/dist/pppd completely
115: and let cvs restore it on next update.
116:
1.256 apb 117: 20140721:
118: The src/external/mit/lua/src directory was accidentally created
119: and then deleted in the CVS repository. If you get errors like
120:
121: cvs [update aborted]: cannot open directory
122: /cvsroot/src/external/mit/lua/src: No such file or directory
123:
124: then delete your local copy of that directory tree and try again.
125:
1.255 joerg 126: 20140530:
127: ARM eABI switched to DWARF based exception handling. This requires
128: rebuilding all C++ code. It is strongly advised to do a clean build.
129:
1.251 martin 130: 20140131:
1.253 joerg 131: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 132: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 133: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 134:
1.250 christos 135: 20131227:
136: 1. The new ntpd runs in a restricted mode to prevent amplification
137: attacks. If you need ntpdc to work you need to explicitly enable
138: mode7 in your config file. Make sure you put the necessary restrict
139: statements to avoid being exposed.
140: 2. strncat has moved from lib/libc to common/lib/libc; you might need
141: to make clean in libc
142:
1.249 mrg 143: 20131129:
144: The GMP sources were updated, and builds will likely fail without
145: cleaning their build trees for both tools and in-tree, like below.
146:
1.248 mrg 147: 20131128:
148: The MPC and MPFR sources were updated, and builds may require their
149: tools and in-tree directories cleaned for successful updates.
150:
1.246 martin 151: 20130605:
1.247 spz 152: The kernel option FAST_IPSEC no longer exists, it's been renamed
153: to IPSEC (and the older IPSEC version removed).
154:
155: 20130605:
1.246 martin 156: Previous freetype installations eroneously installed private
157: header files. If you are building against a non-empty $DESTDIR,
158: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
159:
1.245 mrg 160: 20130531:
161: The xdm update may cause build failure due to xdm.man being
162: in the obj tree. Make sure to ensure any like this:
163: nbmake: nbmake: don't know how to make xdm.man. Stop
164: is fixed by deleting the xdm.man in the obj tree.
165:
1.244 mrg 166: 20130530:
167: Updates of many xsrc packages will leave old .pc files around.
168: Best to clean out the xsrc objdir entirely before rebuilds.
169:
1.242 christos 170: 20130301:
171: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 172: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 173:
1.238 dholland 174: 20120726:
1.241 wiz 175: The update of OpenSSL requires cleaning both the OpenSSL build
176: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 177: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 178: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 179: cause third-party software to link incorrectly and/or crash.
1.238 dholland 180:
1.237 wiz 181: 20120507:
1.241 wiz 182: The database schema for makemandb was changed. You will
1.237 wiz 183: need to update the database using 'makemandb -f' or wait
184: for the next weekly run to fix it.
185:
1.236 bsh 186: 20120319:
187: sys/conf/Makefile.kern.inc has been modified to adjust the
188: size of db_symtab automatically. You need to update dbsym in
189: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
190: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
191: mk.conf.
192:
1.235 joerg 193: 20120216:
1.241 wiz 194: Default for MKCATPAGES changed to NO. Update builds will fail
195: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 196: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 197: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 198: the next run of weekly will fix it.
1.233 joerg 199:
1.232 christos 200: 20111227:
201: If you built between 20111225 and 20111227 you need to remove
202: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
203: bump has been reverted.
204:
1.231 tls 205: 20111125:
206: The "rnd" pseudodevice has been added to sys/conf/std, which
207: means it should no longer be explicitly listed in kernel
208: configuration files. The line "pseudo-device rnd" should be
209: removed from any custom kernel config files users may have.
210:
1.230 tls 211: 20111119:
212: A problem with the datastructures used by the rndctl(8)
213: utility (pointers in datastructures in an array, making 32->64
214: bit compatibility very painful) has been fixed in a
215: non-backwards-compatible way. If you replace your kernel,
216: replace your rndctl executable too.
1.241 wiz 217:
1.229 jym 218: 20111001:
219: the prop_*_send_syscall() functions from proplib(3) have been
220: changed and their new version is not backward compatible with the old
1.241 wiz 221: one. So ensure that all consumers of these functions (currently:
1.229 jym 222: quota2 code and its tests) are updated together with the new lib.
223:
1.228 mrg 224: 20110817:
225: sparc has been changed to use GCC 4.5.3, so any objdir or
226: DESTDIR for them should be deleted before updating.
227:
1.227 riastrad 228: 20110806:
229: i386 and amd64 have been changed to use GCC 4.5.3, so any
230: objdir or DESTDIR for them should be deleted before updating.
231:
1.226 mrg 232: 20110805:
233: The update to GCC 4.5.3 requires a non-trivial portion of
234: the tree to be cleaned. Best to delete both objdir and
235: DESTDIR before running this update. So far, only the
236: sparc64, mips and powerpc platforms have changed.
237:
1.225 matt 238: 20110803:
1.241 wiz 239: The layout of external/public-domain/xz has changed. To do an
1.225 matt 240: update build you will have to remove the contents of the OBJDIR
241: for external/public-domain/xz/bin by hand as the xz entry there
242: is now a directory.
243:
1.223 joerg 244: 20110410:
1.241 wiz 245: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 246: update build you have to clean both tools/binutils and
247: tools/gcc by hand.
1.223 joerg 248:
1.222 plunky 249: 20110328:
250: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 251: ordering issues with "make all". It may be necessary to remove
1.222 plunky 252: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
253: if your update build fails, as the "Xorg" entry there is now a
254: directory.
255:
1.220 joerg 256: 20110121:
1.221 lukem 257: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 258: the build of individual parts of the tree. This is handled
259: correctly by build.sh. Manual builds have to update /usr/share/mk
260: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 261:
1.217 jruoho 262: 20101217:
263: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 264: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 265: group(5) in order to make the program work with existing setups.
266:
1.216 christos 267: 20101125:
268: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 269: variables with names that contain '='. Revision 1.18 of env.c
270: assumed that this was allowed. Installing a new libc with an
1.216 christos 271: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
272: break which affects the autoconf tests for dependency finding,
273: so building gcc will end up printing:
274: checking dependency style of gcc... none
275: configure: error: no usable dependency style found
276: Fix it by rebuilding and re-installing env.
1.138 lukem 277:
1.215 mrg 278: 20101119:
279: Recent Xorg updates in xsrc/external/mit/ may cause various build
280: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
281: have any build problems with xsrc, or problems with mismatched
282: versions between xorg-server and drivers.
283:
1.213 jmmv 284: 20100604:
285: The update of ATF to 0.9 causes old tests written in shell to fail
286: unless they are rebuilt. If you are building with MKUPDATE=yes,
287: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
288: trees by hand.
289:
1.211 tnozaki 290: 20100522:
1.212 mrg 291: Recent Xorg updates in xsrc/external/mit/ will cause various build
292: problems. Delete your entire DESTDIR and OBJDIR if you have any
293: build problems with xsrc.
294:
295: 20100522:
1.211 tnozaki 296: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 297: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 298:
1.210 christos 299: 20100520:
1.241 wiz 300: The location of the xkb compiled descriptions has changed. Please
1.210 christos 301: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
302:
1.209 njoly 303: 20100222:
304: The shared objects file extension has been changed from .so to
305: .pico, in order to avoid conflicts with shared libraries names
306: libXX.so. All now stale regular .so files can be removed from
307: your object directories.
308:
1.208 roy 309: 20100204:
310: The termcap database has been removed from the sources,
311: but has not been marked obsolete so it is not removed
312: from the system when upgrading.
313: As such, you will need to remove them from your object
314: and destination directories.
315:
1.203 dyoung 316: 20091101:
1.205 dholland 317: After updating, it may be necessary to make the 'cleandir'
318: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
319: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
320: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 321:
1.202 mrg 322: 20091001:
1.206 dholland 323: On amd64 you must rebuild tools (to get the new binutils)
324: before building a kernel, or the build fails on cpufunc.S.
325:
326: 20091001:
1.202 mrg 327: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
328: symlink, failing the build. Delete the link, and the subdir
329: it is in, and retry your build.
330:
1.201 dsl 331: 20090718:
332: libc build changed so that strchr() provides the extra entry
1.241 wiz 333: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 334: may fail because the archive contains the unwanted index.o.
335: (Similarly for strrchr() and rindex().)
336:
1.198 mrg 337: 20090709:
338: Native Xorg was upgraded again. Builds will probably fail again
339: without a clean objdir, at least for src/external/mit/xorg.
340:
1.197 mrg 341: 20090616:
342: Native Xorg was upgraded. Builds will need a clean objdir for
343: src/external/mit/xorg. Upgrading a system from sets will not
344: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
345: subdirectory has been changed into a file, and this needs to
346: be manually "rm -r"'ed before installing xbase.tgz.
347:
1.195 perry 348: 20090501:
349: Several new functions were added to string.h/libc, and this
350: can cause autoconf problems during the tool build for people
1.241 wiz 351: who fail to clean out their tools objects properly. If you
1.195 perry 352: note messages about stpcpy, stpncpy or strnlen accompanying a
353: failure during the tool build, clean out all your tools
354: objects and start again.
355:
1.194 mrg 356: 20090325:
357: The i386 port was switched to i486 default toolchain. This requires
358: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
359:
1.192 skrll 360: 20090126:
1.241 wiz 361: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 362: need to 'rm -f __posix_fadvise50.*' in the libc build directory
363: to avoid using the old assembly stub.
1.192 skrll 364:
1.191 joerg 365: 20090202:
366: pkg_install now depends on the pkgdb cache for automatic conflict
367: detection. It is recommented to rebuild the cache with
368: ``pkg_admin rebuild''.
369:
1.184 christos 370: 20090110:
1.241 wiz 371: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
372: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 373: This is needed even in the MODULAR kernel because there is
374: conditionally compiled code in rtsock.c.
1.184 christos 375: 2. make sure build.sh completes and the binaries in a chroot work
376: before installing.
377: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 378: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 379: are installed properly, and start building libraries first libc
380: and libutil, install them and then continue building all the
1.241 wiz 381: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 382: the new libraries are installed, you can restart the build.
383: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 384: rebuild the required packages to update their shared libraries.
385: Any package you rebuild will require rebuilding all the packages
386: that depend on it.
1.186 christos 387: 5. Next time you run pwd_mkdb with the new binary, the file
388: will be upgraded and it will not be backwards compatible.
1.190 apb 389: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
390: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 391: for utmp. You are better off removing the old files after
1.190 apb 392: upgrading. The automated clearing of /var/run during
393: boot, and the automated rotating of files in /var/log by
394: newsyslog(8), may mean that you do not have to remove the
395: files manually.
396: 7. The optional accounting file (/var/account/acct, see
397: accton(8)) has not been versioned, and will need to be
398: removed. The automatic rotation of the accounting file by
399: /etc/daily limits the bad consequences of failure to remove
400: the file.
1.196 dholland 401: 8. Application software that writes time_t to binary files on
1.241 wiz 402: disk will break or need attention. Most notably: if you are

542: has been changed. Rather than modify the pathname (and copy back
543: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 544: root. One side effect is that absolute symlinks inside the emulated

1.1 abs 620: Hints for a more successful build:
621: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 622: Use build.sh, but do not use its "expert mode":
1.132 jmmv 623: This will automatically build the tools in the
1.123 jmc 624: correct order, and it will keep the tools and the
625: new build products from interfering with the running
626: system. This will allow you to ignore most of the
627: other advice in this file.
1.2 mrg 628: Build a new kernel first:
629: This makes sure that any new system calls or features
630: expected by the new userland will be present. This
631: helps to avoid critical errors when upgrading.
1.1 abs 632: Use object directories:
633: This helps to keep stale object
634: files from polluting the build if a Makefile "forgets"
635: about one. It also makes it easier to clean up after
636: a build. It's also necessary if you want to use the
637: same source tree for multiple machines.
1.123 jmc 638: To use object directories with build.sh:
639: a) invoke build.sh with the "-M" or "-O" options.
640: To use object directories without using build.sh:
1.1 abs 641: a) cd /usr/src ; make cleandir
1.2 mrg 642: b) Add "OBJMACHINE=yes" to /etc/mk.conf
643: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 644: d) cd /usr/src ; make build
1.2 mrg 645: Note that running "make obj" in a directory will create
646: in obj.$MACHINE directory.
1.1 abs 647: Build to a DESTDIR:
1.123 jmc 648: This helps to keep old installed files (especially libraries)
649: from interfering with the new build.
650: To build to a DESTDIR with build.sh, use the "-D" option.
651: To build to a DESTDIR without using build.sh, set the DESTDIR
652: environment variable before running make build. It should be
653: set to the pathname of an initially empty directory.
654: Problems: if you do not use build.sh, you might need to
655: update critical utilities without using DESTDIR since
656: nothing is executed from what is installed in DESTDIR.
657: (See critical utils, below.)
1.1 abs 658: Build often:
659: This keeps critical utilities current enough to not choke
660: on any other part of the source tree that depends on up to
1.123 jmc 661: date functionality. If you use build.sh, you should not have
662: this problem.

670: 2) cd share/mk && make install
671: Again, automatically done by make build.
672:
673: Failsafe rebuild of a small part of the tree:
674: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
675: To make sure you rebuild something correctly you want to do
676: something like the following:
677: 1) Make sure the includes and .mk files are up to date.
678: 2) Make sure any program used to build the particular
679: utility is up to date. (yacc, lex, etc...)
680: 3) cd ...path/to/util...
681: make cleandir
682: rm ...all obj directories...
683: make cleandir # yes, again
684: make obj
685: make depend && make
686:
687: Failsafe rebuild of the entire tree:
688: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
689: If you really want to make sure the source tree is clean and
1.2 mrg 690: ready for a build try the following. Note that sourcing /etc/mk.conf
