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.

19: Recent changes:
20: ^^^^^^^^^^^^^^^
1.230 tls 21:
1.274 ! martin 22: 20161009:
! 23: a new version of dhcpcd has been imported with slightly changed
! 24: build infrastructure. When doing a build.sh -u this requires
! 25: pruning the external/bsd/dhcpcd objdir.
! 26:
1.273 mrg 27: 20160914:
28: i386, amd64, shark, ofppc and macppc have joined shark and x68k
29: ports in using xorg-server 1.18. This requires a clean destdir
30: and a clean objdir.
31:
1.272 dholland 32: 20160527:
33: i386 needs a full cleandir or objdir deletion because PIE has
34: been enabled. (see the amd64 entry two down for further info)
35:
1.270 christos 36: 20160418:
37: libedit needs manual removal of all autogenerated files since
1.271 christos 38: some of them are not autogenerated anymore. Remember that there
39: might be two copies of libedit if your platform builds "compat".
1.270 christos 40:
1.268 riastrad 41: 20160410:
42: amd64 needs full "make cleandir" or deletion of objdir now that
43: PIE has been enabled for amd64. PIE, or position-independent
44: executables, means all code, including executables and not just
45: shared libraries, is position-independent and hence able to be
46: relocated by ASLR, address space layout randomization.
47:
48: The change was made in Makefile variables for compiler and
49: linker flags, for which make(1) does not record dependencies,
50: hence it is unable to detect that all .o files need rebuilding.
51:
52: Partial rebuilds with some modified source files will likely
53: fail when linking executables, since the linker refuses to mix
54: position-independent code with position-dependent code in
55: position-independent executables:
56:
57: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
58:
1.267 mrg 59: 20160401:
60: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 61: Some people have found that cleandir is not sufficient, so if
62: in doubt delete the entire object directory tree for gcc.
1.267 mrg 63:
1.266 aymeric 64: 20160306:
1.265 aymeric 65: NetBSD's regexp implementation is now part of libnbcompat.
66: Nblex, nbm4, nbpax, nbsed use it and they may crash on
67: non-NetBSD hosts if linked with stale object files produced
68: while they included a non-NetBSD regex.h.
69: In any case, you should "make cleandir" at least these tools
70: before updating your toolchain.
71:
1.264 martin 72: 20160125:
73: Dtrace has been enabled by default on some architectures.
74: When doing an update build, make sure to clean the etc/mtree
75: object directory before starting the build - otherwise the
76: needed directories in destdir will not be created.
77: An easy way to do this is:
78: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
79:
1.263 dholland 80: 20150818:
81: New acpica requires "make cleandir" in src/external/bsd/acpica
82: again.
83:
1.262 christos 84: 20150413:
85: New acpica requires "make cleandir" and reinstalling yacc
86: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
87: also "make cleandir" in /usr/src/external/bsd/acpica.
88:
1.261 martin 89: 20150404:
90: Lint changes require a full rebuild of the tool, so make
91: sure to build without -u option to build.sh, or manually
92: do a make cleandir in src/tools/lint1 and
93: src/usr.bin/xlint.
94:
1.260 skrll 95: 20150310:
96: Improvements to openssl for arm mean that update builds of
97: the openssl libraries will fail. A make cleandir in
98: external/bsd/openssl/lib is needed
99:
1.258 martin 100: 20141026:
1.259 msaitoh 101: A mishap during the import of pppd may cause your corruption
1.258 martin 102: in your cvs directory if you happened to do a cvs update
103: during a short period of time. To fix, just remove the
104: directory src/external/bsd/ppp/dist/pppd completely
105: and let cvs restore it on next update.
106:
1.256 apb 107: 20140721:
108: The src/external/mit/lua/src directory was accidentally created
109: and then deleted in the CVS repository. If you get errors like
110:
111: cvs [update aborted]: cannot open directory
112: /cvsroot/src/external/mit/lua/src: No such file or directory
113:
114: then delete your local copy of that directory tree and try again.
115:
1.255 joerg 116: 20140530:
117: ARM eABI switched to DWARF based exception handling. This requires
118: rebuilding all C++ code. It is strongly advised to do a clean build.
119:
1.251 martin 120: 20140131:
1.253 joerg 121: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 122: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 123: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 124:
1.250 christos 125: 20131227:
126: 1. The new ntpd runs in a restricted mode to prevent amplification
127: attacks. If you need ntpdc to work you need to explicitly enable
128: mode7 in your config file. Make sure you put the necessary restrict
129: statements to avoid being exposed.
130: 2. strncat has moved from lib/libc to common/lib/libc; you might need
131: to make clean in libc
132:
1.249 mrg 133: 20131129:
134: The GMP sources were updated, and builds will likely fail without
135: cleaning their build trees for both tools and in-tree, like below.
136:
1.248 mrg 137: 20131128:
138: The MPC and MPFR sources were updated, and builds may require their
139: tools and in-tree directories cleaned for successful updates.
140:
1.246 martin 141: 20130605:
1.247 spz 142: The kernel option FAST_IPSEC no longer exists, it's been renamed
143: to IPSEC (and the older IPSEC version removed).
144:
145: 20130605:
1.246 martin 146: Previous freetype installations eroneously installed private
147: header files. If you are building against a non-empty $DESTDIR,
148: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
149:
1.245 mrg 150: 20130531:
151: The xdm update may cause build failure due to xdm.man being
152: in the obj tree. Make sure to ensure any like this:
153: nbmake: nbmake: don't know how to make xdm.man. Stop
154: is fixed by deleting the xdm.man in the obj tree.
155:
1.244 mrg 156: 20130530:
157: Updates of many xsrc packages will leave old .pc files around.
158: Best to clean out the xsrc objdir entirely before rebuilds.
159:
1.242 christos 160: 20130301:
161: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 162: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 163:
1.238 dholland 164: 20120726:
1.241 wiz 165: The update of OpenSSL requires cleaning both the OpenSSL build
166: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 167: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 168: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 169: cause third-party software to link incorrectly and/or crash.
1.238 dholland 170:
1.237 wiz 171: 20120507:
1.241 wiz 172: The database schema for makemandb was changed. You will
1.237 wiz 173: need to update the database using 'makemandb -f' or wait
174: for the next weekly run to fix it.
175:
1.236 bsh 176: 20120319:
177: sys/conf/Makefile.kern.inc has been modified to adjust the
178: size of db_symtab automatically. You need to update dbsym in
179: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
180: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
181: mk.conf.
182:
1.235 joerg 183: 20120216:
1.241 wiz 184: Default for MKCATPAGES changed to NO. Update builds will fail
185: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 186: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 187: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 188: the next run of weekly will fix it.
1.233 joerg 189:
1.232 christos 190: 20111227:
191: If you built between 20111225 and 20111227 you need to remove
192: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
193: bump has been reverted.
194:
1.231 tls 195: 20111125:
196: The "rnd" pseudodevice has been added to sys/conf/std, which
197: means it should no longer be explicitly listed in kernel
198: configuration files. The line "pseudo-device rnd" should be
199: removed from any custom kernel config files users may have.
200:
1.230 tls 201: 20111119:
202: A problem with the datastructures used by the rndctl(8)
203: utility (pointers in datastructures in an array, making 32->64
204: bit compatibility very painful) has been fixed in a
205: non-backwards-compatible way. If you replace your kernel,
206: replace your rndctl executable too.
1.241 wiz 207:
1.229 jym 208: 20111001:
209: the prop_*_send_syscall() functions from proplib(3) have been
210: changed and their new version is not backward compatible with the old
1.241 wiz 211: one. So ensure that all consumers of these functions (currently:
1.229 jym 212: quota2 code and its tests) are updated together with the new lib.
213:
1.228 mrg 214: 20110817:
215: sparc has been changed to use GCC 4.5.3, so any objdir or
216: DESTDIR for them should be deleted before updating.
217:
1.227 riastrad 218: 20110806:
219: i386 and amd64 have been changed to use GCC 4.5.3, so any
220: objdir or DESTDIR for them should be deleted before updating.
221:
1.226 mrg 222: 20110805:
223: The update to GCC 4.5.3 requires a non-trivial portion of
224: the tree to be cleaned. Best to delete both objdir and
225: DESTDIR before running this update. So far, only the
226: sparc64, mips and powerpc platforms have changed.
227:
1.225 matt 228: 20110803:
1.241 wiz 229: The layout of external/public-domain/xz has changed. To do an
1.225 matt 230: update build you will have to remove the contents of the OBJDIR
231: for external/public-domain/xz/bin by hand as the xz entry there
232: is now a directory.
233:
1.223 joerg 234: 20110410:
1.241 wiz 235: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 236: update build you have to clean both tools/binutils and
237: tools/gcc by hand.
1.223 joerg 238:
1.222 plunky 239: 20110328:
240: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 241: ordering issues with "make all". It may be necessary to remove
1.222 plunky 242: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
243: if your update build fails, as the "Xorg" entry there is now a
244: directory.
245:
1.220 joerg 246: 20110121:
1.221 lukem 247: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 248: the build of individual parts of the tree. This is handled
249: correctly by build.sh. Manual builds have to update /usr/share/mk
250: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 251:
1.217 jruoho 252: 20101217:
253: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 254: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 255: group(5) in order to make the program work with existing setups.
256:
1.216 christos 257: 20101125:
258: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 259: variables with names that contain '='. Revision 1.18 of env.c
260: assumed that this was allowed. Installing a new libc with an
1.216 christos 261: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
262: break which affects the autoconf tests for dependency finding,
263: so building gcc will end up printing:
264: checking dependency style of gcc... none
265: configure: error: no usable dependency style found
266: Fix it by rebuilding and re-installing env.
1.138 lukem 267:
1.215 mrg 268: 20101119:
269: Recent Xorg updates in xsrc/external/mit/ may cause various build
270: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
271: have any build problems with xsrc, or problems with mismatched
272: versions between xorg-server and drivers.
273:
1.213 jmmv 274: 20100604:
275: The update of ATF to 0.9 causes old tests written in shell to fail
276: unless they are rebuilt. If you are building with MKUPDATE=yes,
277: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
278: trees by hand.
279:
1.211 tnozaki 280: 20100522:
1.212 mrg 281: Recent Xorg updates in xsrc/external/mit/ will cause various build
282: problems. Delete your entire DESTDIR and OBJDIR if you have any
283: build problems with xsrc.
284:
285: 20100522:
1.211 tnozaki 286: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 287: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 288:
1.210 christos 289: 20100520:
1.241 wiz 290: The location of the xkb compiled descriptions has changed. Please
1.210 christos 291: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
292:
1.209 njoly 293: 20100222:
294: The shared objects file extension has been changed from .so to
295: .pico, in order to avoid conflicts with shared libraries names
296: libXX.so. All now stale regular .so files can be removed from
297: your object directories.
298:
1.208 roy 299: 20100204:
300: The termcap database has been removed from the sources,
301: but has not been marked obsolete so it is not removed
302: from the system when upgrading.
303: As such, you will need to remove them from your object
304: and destination directories.
305:
1.203 dyoung 306: 20091101:
1.205 dholland 307: After updating, it may be necessary to make the 'cleandir'
308: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
309: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
310: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 311:
1.202 mrg 312: 20091001:
1.206 dholland 313: On amd64 you must rebuild tools (to get the new binutils)
314: before building a kernel, or the build fails on cpufunc.S.
315:
316: 20091001:
1.202 mrg 317: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
318: symlink, failing the build. Delete the link, and the subdir
319: it is in, and retry your build.
320:
1.201 dsl 321: 20090718:
322: libc build changed so that strchr() provides the extra entry
1.241 wiz 323: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 324: may fail because the archive contains the unwanted index.o.
325: (Similarly for strrchr() and rindex().)
326:
1.198 mrg 327: 20090709:
328: Native Xorg was upgraded again. Builds will probably fail again
329: without a clean objdir, at least for src/external/mit/xorg.
330:
1.197 mrg 331: 20090616:
332: Native Xorg was upgraded. Builds will need a clean objdir for
333: src/external/mit/xorg. Upgrading a system from sets will not
334: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
335: subdirectory has been changed into a file, and this needs to
336: be manually "rm -r"'ed before installing xbase.tgz.
337:
1.195 perry 338: 20090501:
339: Several new functions were added to string.h/libc, and this
340: can cause autoconf problems during the tool build for people
1.241 wiz 341: who fail to clean out their tools objects properly. If you
1.195 perry 342: note messages about stpcpy, stpncpy or strnlen accompanying a
343: failure during the tool build, clean out all your tools
344: objects and start again.
345:
1.194 mrg 346: 20090325:
347: The i386 port was switched to i486 default toolchain. This requires
348: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
349:
1.192 skrll 350: 20090126:
1.241 wiz 351: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 352: need to 'rm -f __posix_fadvise50.*' in the libc build directory
353: to avoid using the old assembly stub.
1.192 skrll 354:
1.191 joerg 355: 20090202:
356: pkg_install now depends on the pkgdb cache for automatic conflict
357: detection. It is recommented to rebuild the cache with
358: ``pkg_admin rebuild''.
359:
1.184 christos 360: 20090110:
1.241 wiz 361: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
362: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 363: This is needed even in the MODULAR kernel because there is
364: conditionally compiled code in rtsock.c.
1.184 christos 365: 2. make sure build.sh completes and the binaries in a chroot work
366: before installing.
367: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 368: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 369: are installed properly, and start building libraries first libc
370: and libutil, install them and then continue building all the
1.241 wiz 371: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 372: the new libraries are installed, you can restart the build.
373: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 374: rebuild the required packages to update their shared libraries.
375: Any package you rebuild will require rebuilding all the packages
376: that depend on it.
1.186 christos 377: 5. Next time you run pwd_mkdb with the new binary, the file
378: will be upgraded and it will not be backwards compatible.
1.190 apb 379: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
380: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 381: for utmp. You are better off removing the old files after
1.190 apb 382: upgrading. The automated clearing of /var/run during
383: boot, and the automated rotating of files in /var/log by
384: newsyslog(8), may mean that you do not have to remove the
385: files manually.
386: 7. The optional accounting file (/var/account/acct, see
387: accton(8)) has not been versioned, and will need to be
388: removed. The automatic rotation of the accounting file by
389: /etc/daily limits the bad consequences of failure to remove
390: the file.
1.196 dholland 391: 8. Application software that writes time_t to binary files on
1.241 wiz 392: disk will break or need attention. Most notably: if you are
1.196 dholland 393: using PostgreSQL < 8.4, you need to dump your databases,
394: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 395:
1.183 pgoyette 396: 20081219:
397: config(1) has been updated, and one of the files it creates -
398: swapnetbsd.o - has changed format. You need to rebuild config
399: (done automatically by build.sh) and then you need to rerun
400: config on all kernel configuration files before rebuilding those
401: kernels.

532: has been changed. Rather than modify the pathname (and copy back
533: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 534: root. One side effect is that absolute symlinks inside the emulated

1.1 abs 610: Hints for a more successful build:
611: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 612: Use build.sh, but do not use its "expert mode":
1.132 jmmv 613: This will automatically build the tools in the
1.123 jmc 614: correct order, and it will keep the tools and the
615: new build products from interfering with the running
616: system. This will allow you to ignore most of the
617: other advice in this file.
1.2 mrg 618: Build a new kernel first:
619: This makes sure that any new system calls or features
620: expected by the new userland will be present. This
621: helps to avoid critical errors when upgrading.
1.1 abs 622: Use object directories:
623: This helps to keep stale object
624: files from polluting the build if a Makefile "forgets"
625: about one. It also makes it easier to clean up after
626: a build. It's also necessary if you want to use the
627: same source tree for multiple machines.
1.123 jmc 628: To use object directories with build.sh:
629: a) invoke build.sh with the "-M" or "-O" options.
630: To use object directories without using build.sh:
1.1 abs 631: a) cd /usr/src ; make cleandir
1.2 mrg 632: b) Add "OBJMACHINE=yes" to /etc/mk.conf
633: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 634: d) cd /usr/src ; make build
1.2 mrg 635: Note that running "make obj" in a directory will create
636: in obj.$MACHINE directory.
1.1 abs 637: Build to a DESTDIR:
1.123 jmc 638: This helps to keep old installed files (especially libraries)
639: from interfering with the new build.
640: To build to a DESTDIR with build.sh, use the "-D" option.
641: To build to a DESTDIR without using build.sh, set the DESTDIR
642: environment variable before running make build. It should be
643: set to the pathname of an initially empty directory.
644: Problems: if you do not use build.sh, you might need to
645: update critical utilities without using DESTDIR since
646: nothing is executed from what is installed in DESTDIR.
647: (See critical utils, below.)
1.1 abs 648: Build often:
649: This keeps critical utilities current enough to not choke
650: on any other part of the source tree that depends on up to
1.123 jmc 651: date functionality. If you use build.sh, you should not have
652: this problem.

1.230 tls 656: When things don't work there are usually a few things that commonly

660: 2) cd share/mk && make install
661: Again, automatically done by make build.
662:
663: Failsafe rebuild of a small part of the tree:
664: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
665: To make sure you rebuild something correctly you want to do
666: something like the following:
667: 1) Make sure the includes and .mk files are up to date.
668: 2) Make sure any program used to build the particular
669: utility is up to date. (yacc, lex, etc...)
670: 3) cd ...path/to/util...
671: make cleandir
672: rm ...all obj directories...
673: make cleandir # yes, again
674: make obj
675: make depend && make
676:
677: Failsafe rebuild of the entire tree:
678: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
679: If you really want to make sure the source tree is clean and
1.2 mrg 680: ready for a build try the following. Note that sourcing /etc/mk.conf
