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:
1.278 kre 22: 20170107:
23: various arch dependent libc/exect.S files were removed
1.279 ! kre 24: Either remove the obj directories (lib/libc and compat/amd64/i386/lib
! 25: if it exists) or do a clean build.
! 26: (This is a bug in the make system, it should be corrected without
! 27: human intervention, but isn't.)
1.278 kre 28:
1.277 martin 29: 20170104:
30: xinput build options have changed.
31: Remove the obj directory (external/mit/xorg/bin/xinput)
32: if you build.sh -u
33:
1.276 martin 34: 20170103:
35: a new version of flex has been imported.
36: Remove the file from obj (external/bsd/flex)
37: if you build.sh -u
38:
1.275 spz 39: 20161014:
40: a new version of OpenSSL has been imported.
41: Remove the files from obj (crypto/external/bsd/openssl)
42: if you build.sh -u
43:
1.274 martin 44: 20161009:
45: a new version of dhcpcd has been imported with slightly changed
46: build infrastructure. When doing a build.sh -u this requires
47: pruning the external/bsd/dhcpcd objdir.
48:
1.273 mrg 49: 20160914:
50: i386, amd64, shark, ofppc and macppc have joined shark and x68k
51: ports in using xorg-server 1.18. This requires a clean destdir
52: and a clean objdir.
53:
1.272 dholland 54: 20160527:
55: i386 needs a full cleandir or objdir deletion because PIE has
56: been enabled. (see the amd64 entry two down for further info)
57:
1.270 christos 58: 20160418:
59: libedit needs manual removal of all autogenerated files since
1.271 christos 60: some of them are not autogenerated anymore. Remember that there
61: might be two copies of libedit if your platform builds "compat".
1.270 christos 62:
1.268 riastrad 63: 20160410:
64: amd64 needs full "make cleandir" or deletion of objdir now that
65: PIE has been enabled for amd64. PIE, or position-independent
66: executables, means all code, including executables and not just
67: shared libraries, is position-independent and hence able to be
68: relocated by ASLR, address space layout randomization.
69:
70: The change was made in Makefile variables for compiler and
71: linker flags, for which make(1) does not record dependencies,
72: hence it is unable to detect that all .o files need rebuilding.
73:
74: Partial rebuilds with some modified source files will likely
75: fail when linking executables, since the linker refuses to mix
76: position-independent code with position-dependent code in
77: position-independent executables:
78:
79: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
80:
1.267 mrg 81: 20160401:
82: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 83: Some people have found that cleandir is not sufficient, so if
84: in doubt delete the entire object directory tree for gcc.
1.267 mrg 85:
1.266 aymeric 86: 20160306:
1.265 aymeric 87: NetBSD's regexp implementation is now part of libnbcompat.
88: Nblex, nbm4, nbpax, nbsed use it and they may crash on
89: non-NetBSD hosts if linked with stale object files produced
90: while they included a non-NetBSD regex.h.
91: In any case, you should "make cleandir" at least these tools
92: before updating your toolchain.
93:
1.264 martin 94: 20160125:
95: Dtrace has been enabled by default on some architectures.
96: When doing an update build, make sure to clean the etc/mtree
97: object directory before starting the build - otherwise the
98: needed directories in destdir will not be created.
99: An easy way to do this is:
100: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
101:
1.263 dholland 102: 20150818:
103: New acpica requires "make cleandir" in src/external/bsd/acpica
104: again.
105:
1.262 christos 106: 20150413:
107: New acpica requires "make cleandir" and reinstalling yacc
108: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
109: also "make cleandir" in /usr/src/external/bsd/acpica.
110:
1.261 martin 111: 20150404:
112: Lint changes require a full rebuild of the tool, so make
113: sure to build without -u option to build.sh, or manually
114: do a make cleandir in src/tools/lint1 and
115: src/usr.bin/xlint.
116:
1.260 skrll 117: 20150310:
118: Improvements to openssl for arm mean that update builds of
119: the openssl libraries will fail. A make cleandir in
120: external/bsd/openssl/lib is needed
121:
1.258 martin 122: 20141026:
1.259 msaitoh 123: A mishap during the import of pppd may cause your corruption
1.258 martin 124: in your cvs directory if you happened to do a cvs update
125: during a short period of time. To fix, just remove the
126: directory src/external/bsd/ppp/dist/pppd completely
127: and let cvs restore it on next update.
128:
1.256 apb 129: 20140721:
130: The src/external/mit/lua/src directory was accidentally created
131: and then deleted in the CVS repository. If you get errors like
132:
133: cvs [update aborted]: cannot open directory
134: /cvsroot/src/external/mit/lua/src: No such file or directory
135:
136: then delete your local copy of that directory tree and try again.
137:
1.255 joerg 138: 20140530:
139: ARM eABI switched to DWARF based exception handling. This requires
140: rebuilding all C++ code. It is strongly advised to do a clean build.
141:
1.251 martin 142: 20140131:
1.253 joerg 143: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 144: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 145: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 146:
1.250 christos 147: 20131227:
148: 1. The new ntpd runs in a restricted mode to prevent amplification
149: attacks. If you need ntpdc to work you need to explicitly enable
150: mode7 in your config file. Make sure you put the necessary restrict
151: statements to avoid being exposed.
152: 2. strncat has moved from lib/libc to common/lib/libc; you might need
153: to make clean in libc
154:
1.249 mrg 155: 20131129:
156: The GMP sources were updated, and builds will likely fail without
157: cleaning their build trees for both tools and in-tree, like below.
158:
1.248 mrg 159: 20131128:
160: The MPC and MPFR sources were updated, and builds may require their
161: tools and in-tree directories cleaned for successful updates.
162:
1.246 martin 163: 20130605:
1.247 spz 164: The kernel option FAST_IPSEC no longer exists, it's been renamed
165: to IPSEC (and the older IPSEC version removed).
166:
167: 20130605:
1.246 martin 168: Previous freetype installations eroneously installed private
169: header files. If you are building against a non-empty $DESTDIR,
170: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
171:
1.245 mrg 172: 20130531:
173: The xdm update may cause build failure due to xdm.man being
174: in the obj tree. Make sure to ensure any like this:
175: nbmake: nbmake: don't know how to make xdm.man. Stop
176: is fixed by deleting the xdm.man in the obj tree.
177:
1.244 mrg 178: 20130530:
179: Updates of many xsrc packages will leave old .pc files around.
180: Best to clean out the xsrc objdir entirely before rebuilds.
181:
1.242 christos 182: 20130301:
183: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 184: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 185:
1.238 dholland 186: 20120726:
1.241 wiz 187: The update of OpenSSL requires cleaning both the OpenSSL build
188: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 189: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 190: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 191: cause third-party software to link incorrectly and/or crash.
1.238 dholland 192:
1.237 wiz 193: 20120507:
1.241 wiz 194: The database schema for makemandb was changed. You will
1.237 wiz 195: need to update the database using 'makemandb -f' or wait
196: for the next weekly run to fix it.
197:
1.236 bsh 198: 20120319:
199: sys/conf/Makefile.kern.inc has been modified to adjust the
200: size of db_symtab automatically. You need to update dbsym in
201: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
202: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
203: mk.conf.
204:
1.235 joerg 205: 20120216:
1.241 wiz 206: Default for MKCATPAGES changed to NO. Update builds will fail
207: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 208: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 209: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 210: the next run of weekly will fix it.
1.233 joerg 211:
1.232 christos 212: 20111227:
213: If you built between 20111225 and 20111227 you need to remove
214: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
215: bump has been reverted.
216:
1.231 tls 217: 20111125:
218: The "rnd" pseudodevice has been added to sys/conf/std, which
219: means it should no longer be explicitly listed in kernel
220: configuration files. The line "pseudo-device rnd" should be
221: removed from any custom kernel config files users may have.
222:
1.230 tls 223: 20111119:
224: A problem with the datastructures used by the rndctl(8)
225: utility (pointers in datastructures in an array, making 32->64
226: bit compatibility very painful) has been fixed in a
227: non-backwards-compatible way. If you replace your kernel,
228: replace your rndctl executable too.
1.241 wiz 229:
1.229 jym 230: 20111001:
231: the prop_*_send_syscall() functions from proplib(3) have been
232: changed and their new version is not backward compatible with the old
1.241 wiz 233: one. So ensure that all consumers of these functions (currently:
1.229 jym 234: quota2 code and its tests) are updated together with the new lib.
235:
1.228 mrg 236: 20110817:
237: sparc has been changed to use GCC 4.5.3, so any objdir or
238: DESTDIR for them should be deleted before updating.
239:
1.227 riastrad 240: 20110806:
241: i386 and amd64 have been changed to use GCC 4.5.3, so any
242: objdir or DESTDIR for them should be deleted before updating.
243:
1.226 mrg 244: 20110805:
245: The update to GCC 4.5.3 requires a non-trivial portion of
246: the tree to be cleaned. Best to delete both objdir and
247: DESTDIR before running this update. So far, only the
248: sparc64, mips and powerpc platforms have changed.
249:
1.225 matt 250: 20110803:
1.241 wiz 251: The layout of external/public-domain/xz has changed. To do an
1.225 matt 252: update build you will have to remove the contents of the OBJDIR
253: for external/public-domain/xz/bin by hand as the xz entry there
254: is now a directory.
255:
1.223 joerg 256: 20110410:
1.241 wiz 257: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 258: update build you have to clean both tools/binutils and
259: tools/gcc by hand.
1.223 joerg 260:
1.222 plunky 261: 20110328:
262: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 263: ordering issues with "make all". It may be necessary to remove
1.222 plunky 264: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
265: if your update build fails, as the "Xorg" entry there is now a
266: directory.
267:
1.220 joerg 268: 20110121:
1.221 lukem 269: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 270: the build of individual parts of the tree. This is handled
271: correctly by build.sh. Manual builds have to update /usr/share/mk
272: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 273:
1.217 jruoho 274: 20101217:
275: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 276: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 277: group(5) in order to make the program work with existing setups.
278:
1.216 christos 279: 20101125:
280: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 281: variables with names that contain '='. Revision 1.18 of env.c
282: assumed that this was allowed. Installing a new libc with an
1.216 christos 283: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
284: break which affects the autoconf tests for dependency finding,
285: so building gcc will end up printing:
286: checking dependency style of gcc... none
287: configure: error: no usable dependency style found
288: Fix it by rebuilding and re-installing env.
1.138 lukem 289:
1.215 mrg 290: 20101119:
291: Recent Xorg updates in xsrc/external/mit/ may cause various build
292: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
293: have any build problems with xsrc, or problems with mismatched
294: versions between xorg-server and drivers.
295:
1.213 jmmv 296: 20100604:
297: The update of ATF to 0.9 causes old tests written in shell to fail
298: unless they are rebuilt. If you are building with MKUPDATE=yes,
299: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
300: trees by hand.
301:
1.211 tnozaki 302: 20100522:
1.212 mrg 303: Recent Xorg updates in xsrc/external/mit/ will cause various build
304: problems. Delete your entire DESTDIR and OBJDIR if you have any
305: build problems with xsrc.
306:
307: 20100522:
1.211 tnozaki 308: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 309: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 310:
1.210 christos 311: 20100520:
1.241 wiz 312: The location of the xkb compiled descriptions has changed. Please
1.210 christos 313: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
314:
1.209 njoly 315: 20100222:
316: The shared objects file extension has been changed from .so to
317: .pico, in order to avoid conflicts with shared libraries names
318: libXX.so. All now stale regular .so files can be removed from
319: your object directories.
320:
1.208 roy 321: 20100204:
322: The termcap database has been removed from the sources,
323: but has not been marked obsolete so it is not removed
324: from the system when upgrading.
325: As such, you will need to remove them from your object
326: and destination directories.
327:
1.203 dyoung 328: 20091101:
1.205 dholland 329: After updating, it may be necessary to make the 'cleandir'
330: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
331: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
332: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 333:
1.202 mrg 334: 20091001:
1.206 dholland 335: On amd64 you must rebuild tools (to get the new binutils)
336: before building a kernel, or the build fails on cpufunc.S.
337:
338: 20091001:
1.202 mrg 339: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
340: symlink, failing the build. Delete the link, and the subdir
341: it is in, and retry your build.
342:
1.201 dsl 343: 20090718:
344: libc build changed so that strchr() provides the extra entry
1.241 wiz 345: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 346: may fail because the archive contains the unwanted index.o.
347: (Similarly for strrchr() and rindex().)
348:
1.198 mrg 349: 20090709:
350: Native Xorg was upgraded again. Builds will probably fail again
351: without a clean objdir, at least for src/external/mit/xorg.
352:
1.197 mrg 353: 20090616:
354: Native Xorg was upgraded. Builds will need a clean objdir for
355: src/external/mit/xorg. Upgrading a system from sets will not
356: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
357: subdirectory has been changed into a file, and this needs to
358: be manually "rm -r"'ed before installing xbase.tgz.
359:
1.195 perry 360: 20090501:
361: Several new functions were added to string.h/libc, and this
362: can cause autoconf problems during the tool build for people
1.241 wiz 363: who fail to clean out their tools objects properly. If you
1.195 perry 364: note messages about stpcpy, stpncpy or strnlen accompanying a
365: failure during the tool build, clean out all your tools
366: objects and start again.
367:
1.194 mrg 368: 20090325:
369: The i386 port was switched to i486 default toolchain. This requires
370: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
371:
1.192 skrll 372: 20090126:
1.241 wiz 373: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 374: need to 'rm -f __posix_fadvise50.*' in the libc build directory
375: to avoid using the old assembly stub.
1.192 skrll 376:
1.191 joerg 377: 20090202:
378: pkg_install now depends on the pkgdb cache for automatic conflict
379: detection. It is recommented to rebuild the cache with
380: ``pkg_admin rebuild''.
381:
1.184 christos 382: 20090110:
1.241 wiz 383: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
384: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 385: This is needed even in the MODULAR kernel because there is
386: conditionally compiled code in rtsock.c.
1.184 christos 387: 2. make sure build.sh completes and the binaries in a chroot work
388: before installing.
389: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 390: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 391: are installed properly, and start building libraries first libc
392: and libutil, install them and then continue building all the
1.241 wiz 393: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 394: the new libraries are installed, you can restart the build.
395: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 396: rebuild the required packages to update their shared libraries.
397: Any package you rebuild will require rebuilding all the packages
398: that depend on it.
1.186 christos 399: 5. Next time you run pwd_mkdb with the new binary, the file
400: will be upgraded and it will not be backwards compatible.
1.190 apb 401: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
402: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 403: for utmp. You are better off removing the old files after
1.190 apb 404: upgrading. The automated clearing of /var/run during

1.182 tsutsui 431: On i386, various kernel options(4) in GENERIC including
1.180 wiz 432: file systems have been disabled and moved into kernel modules.
433: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 434: following files as well as a new GENERIC kernel:
435:

1.180 wiz 439: for the file system from which the kernel is loaded automatically
1.179 tsutsui 440:
1.180 wiz 441: If you have to load your kernel from a file system which is not of

538: enumerate interfaces was fixed. The bug began to cause
539: problems after 20070911 when the kernel's SIOCGIFCONF
540: implementation was repaired. From 20070529 to 20070911 racoon

1.161 dsl 552: 20070422:

554: has been changed. Rather than modify the pathname (and copy back
555: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 556: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 557: root file system will be relative to that file system - unless they
1.161 dsl 558: start /../ this is useful when the emulated root is a real install

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

1.1 abs 632: Hints for a more successful build:
633: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 634: Use build.sh, but do not use its "expert mode":
1.132 jmmv 635: This will automatically build the tools in the
1.123 jmc 636: correct order, and it will keep the tools and the
637: new build products from interfering with the running
638: system. This will allow you to ignore most of the
639: other advice in this file.
1.2 mrg 640: Build a new kernel first:
641: This makes sure that any new system calls or features
642: expected by the new userland will be present. This
643: helps to avoid critical errors when upgrading.
1.1 abs 644: Use object directories:
645: This helps to keep stale object
646: files from polluting the build if a Makefile "forgets"
647: about one. It also makes it easier to clean up after
648: a build. It's also necessary if you want to use the
649: same source tree for multiple machines.
1.123 jmc 650: To use object directories with build.sh:
651: a) invoke build.sh with the "-M" or "-O" options.
652: To use object directories without using build.sh:
1.1 abs 653: a) cd /usr/src ; make cleandir
1.2 mrg 654: b) Add "OBJMACHINE=yes" to /etc/mk.conf
655: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 656: d) cd /usr/src ; make build
1.2 mrg 657: Note that running "make obj" in a directory will create
658: in obj.$MACHINE directory.
1.1 abs 659: Build to a DESTDIR:
1.123 jmc 660: This helps to keep old installed files (especially libraries)
661: from interfering with the new build.
662: To build to a DESTDIR with build.sh, use the "-D" option.
663: To build to a DESTDIR without using build.sh, set the DESTDIR
664: environment variable before running make build. It should be
665: set to the pathname of an initially empty directory.
666: Problems: if you do not use build.sh, you might need to
667: update critical utilities without using DESTDIR since
668: nothing is executed from what is installed in DESTDIR.
669: (See critical utils, below.)
1.1 abs 670: Build often:
671: This keeps critical utilities current enough to not choke
672: on any other part of the source tree that depends on up to
1.123 jmc 673: date functionality. If you use build.sh, you should not have
674: this problem.

684:
685: Failsafe rebuild of a small part of the tree:
686: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
687: To make sure you rebuild something correctly you want to do
688: something like the following:
689: 1) Make sure the includes and .mk files are up to date.
690: 2) Make sure any program used to build the particular
691: utility is up to date. (yacc, lex, etc...)
692: 3) cd ...path/to/util...
693: make cleandir
694: rm ...all obj directories...
695: make cleandir # yes, again
696: make obj
697: make depend && make
698:
699: Failsafe rebuild of the entire tree:
700: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
701: If you really want to make sure the source tree is clean and
1.2 mrg 702: ready for a build try the following. Note that sourcing /etc/mk.conf
