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:
1.292 ! mrg 22: 20180311:
! 23: bdftopcf was updated and may need cleaning in the
! 24: src/external/mit/xorg/tools/bdftopcf subdirectory if there are
! 25: link errors.
! 26:
1.291 mrg 27: 20180212:
28: between OpenSSL and GCC updates, many things may fail to build.
29: any failure that looks like GCC or openssl is best handled by
30: a clean destdir and objdir. Full cleandir and destdir deletion
31: is recommended if build failures occur.
32:
1.288 martin 33: 20171225:
34: removal of the vadvise syscall requires manual removal of all
35: associated files from the libc build object directory (including
1.289 christos 36: the .depend files) - a command like:
1.288 martin 37: cd $OBJ && find . -type d -name libc | xargs rm -rf
1.289 christos 38: For architectures that support multiple "compat" binary targets,
39: you'll need to cleanup both the regular libc directory and the
1.290 martin 40: compat ones (the above command will do that).
1.288 martin 41:
1.287 kre 42: 20171010:
43: a change to the build structure of external/bsd/acpica/bin/iasl
44: means that its objdir (or *.d and .depend at least) might need
45: to be manually removed - or a build done once without -u.
46:
1.286 mrg 47: 20170822:
48: a new version of GMP has been imported and probably
49: will break parts of builds related to themselves or GCC, both
50: in the tools and the native section. Remove all GCC, GMP, MPFR
51: and MPC objdirs or build once without -u.
52:
1.285 mrg 53: 20170816:
54: a new version of MPFR and MPC have been imported and probably
55: will break parts of builds related to themselves or GCC, both
56: in the tools and the native section. Remove all GCC, GMP, MPFR
57: and MPC objdirs or build once without -u.
58:
1.284 martin 59: 20170402:
60: a new version of dhcpcd has been imported, which does not support
61: update builds from the previous version. Remove your
62: external/bsd/dhcpcd object dir or build once without -u.
63:
1.281 roy 64: 20170211:
65: a new terminfo database has been imported.
66: The structure of it has changed slightly from prior versions and
67: an updated tic tool is required.
68: If you build.sh, don't use -u
69:
1.280 kre 70: 20170207:
1.278 kre 71: various arch dependent libc/exect.S files were removed
1.279 kre 72: Either remove the obj directories (lib/libc and compat/amd64/i386/lib
73: if it exists) or do a clean build.
74: (This is a bug in the make system, it should be corrected without
75: human intervention, but isn't.)
1.278 kre 76:
1.277 martin 77: 20170104:
78: xinput build options have changed.
79: Remove the obj directory (external/mit/xorg/bin/xinput)
80: if you build.sh -u
81:
1.276 martin 82: 20170103:
83: a new version of flex has been imported.
84: Remove the file from obj (external/bsd/flex)
85: if you build.sh -u
86:
1.275 spz 87: 20161014:
88: a new version of OpenSSL has been imported.
89: Remove the files from obj (crypto/external/bsd/openssl)
90: if you build.sh -u
91:
1.274 martin 92: 20161009:
93: a new version of dhcpcd has been imported with slightly changed
94: build infrastructure. When doing a build.sh -u this requires
95: pruning the external/bsd/dhcpcd objdir.
96:
1.273 mrg 97: 20160914:
98: i386, amd64, shark, ofppc and macppc have joined shark and x68k
99: ports in using xorg-server 1.18. This requires a clean destdir
100: and a clean objdir.
101:
1.272 dholland 102: 20160527:
103: i386 needs a full cleandir or objdir deletion because PIE has
104: been enabled. (see the amd64 entry two down for further info)
105:
1.270 christos 106: 20160418:
107: libedit needs manual removal of all autogenerated files since
1.271 christos 108: some of them are not autogenerated anymore. Remember that there
109: might be two copies of libedit if your platform builds "compat".
1.270 christos 110:
1.268 riastrad 111: 20160410:
112: amd64 needs full "make cleandir" or deletion of objdir now that
113: PIE has been enabled for amd64. PIE, or position-independent
114: executables, means all code, including executables and not just
115: shared libraries, is position-independent and hence able to be
116: relocated by ASLR, address space layout randomization.
117:
118: The change was made in Makefile variables for compiler and
119: linker flags, for which make(1) does not record dependencies,
120: hence it is unable to detect that all .o files need rebuilding.
121:
122: Partial rebuilds with some modified source files will likely
123: fail when linking executables, since the linker refuses to mix
124: position-independent code with position-dependent code in
125: position-independent executables:
126:
127: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
128:
1.267 mrg 129: 20160401:
130: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 131: Some people have found that cleandir is not sufficient, so if
132: in doubt delete the entire object directory tree for gcc.
1.267 mrg 133:
1.266 aymeric 134: 20160306:
1.265 aymeric 135: NetBSD's regexp implementation is now part of libnbcompat.
136: Nblex, nbm4, nbpax, nbsed use it and they may crash on
137: non-NetBSD hosts if linked with stale object files produced
138: while they included a non-NetBSD regex.h.
139: In any case, you should "make cleandir" at least these tools
140: before updating your toolchain.
141:
1.264 martin 142: 20160125:
143: Dtrace has been enabled by default on some architectures.
144: When doing an update build, make sure to clean the etc/mtree
145: object directory before starting the build - otherwise the
146: needed directories in destdir will not be created.
147: An easy way to do this is:
148: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
149:
1.263 dholland 150: 20150818:
151: New acpica requires "make cleandir" in src/external/bsd/acpica
152: again.
153:
1.262 christos 154: 20150413:
155: New acpica requires "make cleandir" and reinstalling yacc
156: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
157: also "make cleandir" in /usr/src/external/bsd/acpica.
158:
1.261 martin 159: 20150404:
160: Lint changes require a full rebuild of the tool, so make
161: sure to build without -u option to build.sh, or manually
162: do a make cleandir in src/tools/lint1 and
163: src/usr.bin/xlint.
164:
1.260 skrll 165: 20150310:
166: Improvements to openssl for arm mean that update builds of
167: the openssl libraries will fail. A make cleandir in
168: external/bsd/openssl/lib is needed
169:
1.258 martin 170: 20141026:
1.259 msaitoh 171: A mishap during the import of pppd may cause your corruption
1.258 martin 172: in your cvs directory if you happened to do a cvs update
173: during a short period of time. To fix, just remove the
174: directory src/external/bsd/ppp/dist/pppd completely
175: and let cvs restore it on next update.
176:
1.256 apb 177: 20140721:
178: The src/external/mit/lua/src directory was accidentally created
179: and then deleted in the CVS repository. If you get errors like
180:
181: cvs [update aborted]: cannot open directory
182: /cvsroot/src/external/mit/lua/src: No such file or directory
183:
184: then delete your local copy of that directory tree and try again.
185:
1.255 joerg 186: 20140530:
187: ARM eABI switched to DWARF based exception handling. This requires
188: rebuilding all C++ code. It is strongly advised to do a clean build.
189:
1.251 martin 190: 20140131:
1.253 joerg 191: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 192: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 193: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 194:
1.250 christos 195: 20131227:
196: 1. The new ntpd runs in a restricted mode to prevent amplification
197: attacks. If you need ntpdc to work you need to explicitly enable
198: mode7 in your config file. Make sure you put the necessary restrict
199: statements to avoid being exposed.
200: 2. strncat has moved from lib/libc to common/lib/libc; you might need
201: to make clean in libc
202:
1.249 mrg 203: 20131129:
204: The GMP sources were updated, and builds will likely fail without
205: cleaning their build trees for both tools and in-tree, like below.
206:
1.248 mrg 207: 20131128:
208: The MPC and MPFR sources were updated, and builds may require their
209: tools and in-tree directories cleaned for successful updates.
210:
1.246 martin 211: 20130605:
1.247 spz 212: The kernel option FAST_IPSEC no longer exists, it's been renamed
213: to IPSEC (and the older IPSEC version removed).
214:
215: 20130605:
1.246 martin 216: Previous freetype installations eroneously installed private
217: header files. If you are building against a non-empty $DESTDIR,
218: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
219:
1.245 mrg 220: 20130531:
221: The xdm update may cause build failure due to xdm.man being
222: in the obj tree. Make sure to ensure any like this:
223: nbmake: nbmake: don't know how to make xdm.man. Stop
224: is fixed by deleting the xdm.man in the obj tree.
225:
1.244 mrg 226: 20130530:
227: Updates of many xsrc packages will leave old .pc files around.
228: Best to clean out the xsrc objdir entirely before rebuilds.
229:
1.242 christos 230: 20130301:
231: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 232: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 233:
1.238 dholland 234: 20120726:
1.241 wiz 235: The update of OpenSSL requires cleaning both the OpenSSL build
236: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 237: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 238: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 239: cause third-party software to link incorrectly and/or crash.
1.238 dholland 240:
1.237 wiz 241: 20120507:
1.241 wiz 242: The database schema for makemandb was changed. You will
1.237 wiz 243: need to update the database using 'makemandb -f' or wait
244: for the next weekly run to fix it.
245:
1.236 bsh 246: 20120319:
247: sys/conf/Makefile.kern.inc has been modified to adjust the
248: size of db_symtab automatically. You need to update dbsym in
249: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
250: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
251: mk.conf.
252:
1.235 joerg 253: 20120216:
1.241 wiz 254: Default for MKCATPAGES changed to NO. Update builds will fail
255: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 256: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 257: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 258: the next run of weekly will fix it.
1.233 joerg 259:
1.232 christos 260: 20111227:
261: If you built between 20111225 and 20111227 you need to remove
262: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
263: bump has been reverted.
264:
1.231 tls 265: 20111125:
266: The "rnd" pseudodevice has been added to sys/conf/std, which
267: means it should no longer be explicitly listed in kernel
268: configuration files. The line "pseudo-device rnd" should be
269: removed from any custom kernel config files users may have.
270:
1.230 tls 271: 20111119:
272: A problem with the datastructures used by the rndctl(8)
273: utility (pointers in datastructures in an array, making 32->64
274: bit compatibility very painful) has been fixed in a
275: non-backwards-compatible way. If you replace your kernel,
276: replace your rndctl executable too.
1.241 wiz 277:
1.229 jym 278: 20111001:
279: the prop_*_send_syscall() functions from proplib(3) have been
280: changed and their new version is not backward compatible with the old
1.241 wiz 281: one. So ensure that all consumers of these functions (currently:
1.229 jym 282: quota2 code and its tests) are updated together with the new lib.
283:
1.228 mrg 284: 20110817:
285: sparc has been changed to use GCC 4.5.3, so any objdir or
286: DESTDIR for them should be deleted before updating.
287:
1.227 riastrad 288: 20110806:
289: i386 and amd64 have been changed to use GCC 4.5.3, so any
290: objdir or DESTDIR for them should be deleted before updating.
291:
1.226 mrg 292: 20110805:
293: The update to GCC 4.5.3 requires a non-trivial portion of
294: the tree to be cleaned. Best to delete both objdir and
295: DESTDIR before running this update. So far, only the
296: sparc64, mips and powerpc platforms have changed.
297:
1.225 matt 298: 20110803:
1.241 wiz 299: The layout of external/public-domain/xz has changed. To do an
1.225 matt 300: update build you will have to remove the contents of the OBJDIR
301: for external/public-domain/xz/bin by hand as the xz entry there
302: is now a directory.
303:
1.223 joerg 304: 20110410:
1.241 wiz 305: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 306: update build you have to clean both tools/binutils and
307: tools/gcc by hand.
1.223 joerg 308:
1.222 plunky 309: 20110328:
310: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 311: ordering issues with "make all". It may be necessary to remove
1.222 plunky 312: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
313: if your update build fails, as the "Xorg" entry there is now a
314: directory.
315:
1.220 joerg 316: 20110121:
1.221 lukem 317: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 318: the build of individual parts of the tree. This is handled
319: correctly by build.sh. Manual builds have to update /usr/share/mk
320: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 321:
1.217 jruoho 322: 20101217:
323: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 324: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 325: group(5) in order to make the program work with existing setups.
326:
1.216 christos 327: 20101125:
328: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 329: variables with names that contain '='. Revision 1.18 of env.c
330: assumed that this was allowed. Installing a new libc with an
1.216 christos 331: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
332: break which affects the autoconf tests for dependency finding,
333: so building gcc will end up printing:
334: checking dependency style of gcc... none
335: configure: error: no usable dependency style found
336: Fix it by rebuilding and re-installing env.
1.138 lukem 337:
1.215 mrg 338: 20101119:
339: Recent Xorg updates in xsrc/external/mit/ may cause various build
340: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
341: have any build problems with xsrc, or problems with mismatched
342: versions between xorg-server and drivers.
343:
1.213 jmmv 344: 20100604:
345: The update of ATF to 0.9 causes old tests written in shell to fail
346: unless they are rebuilt. If you are building with MKUPDATE=yes,
347: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
348: trees by hand.
349:
1.211 tnozaki 350: 20100522:
1.212 mrg 351: Recent Xorg updates in xsrc/external/mit/ will cause various build
352: problems. Delete your entire DESTDIR and OBJDIR if you have any
353: build problems with xsrc.
354:
355: 20100522:
1.211 tnozaki 356: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 357: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 358:
1.210 christos 359: 20100520:
1.241 wiz 360: The location of the xkb compiled descriptions has changed. Please
1.210 christos 361: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
362:
1.209 njoly 363: 20100222:
364: The shared objects file extension has been changed from .so to
365: .pico, in order to avoid conflicts with shared libraries names
366: libXX.so. All now stale regular .so files can be removed from
367: your object directories.
368:
1.208 roy 369: 20100204:
370: The termcap database has been removed from the sources,
371: but has not been marked obsolete so it is not removed
372: from the system when upgrading.
373: As such, you will need to remove them from your object
374: and destination directories.
375:
1.203 dyoung 376: 20091101:
1.205 dholland 377: After updating, it may be necessary to make the 'cleandir'
378: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
379: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
380: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 381:
1.202 mrg 382: 20091001:
1.206 dholland 383: On amd64 you must rebuild tools (to get the new binutils)
384: before building a kernel, or the build fails on cpufunc.S.
385:
386: 20091001:
1.202 mrg 387: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
388: symlink, failing the build. Delete the link, and the subdir
389: it is in, and retry your build.
390:
1.201 dsl 391: 20090718:
392: libc build changed so that strchr() provides the extra entry
1.241 wiz 393: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 394: may fail because the archive contains the unwanted index.o.
395: (Similarly for strrchr() and rindex().)
396:
1.198 mrg 397: 20090709:
398: Native Xorg was upgraded again. Builds will probably fail again
399: without a clean objdir, at least for src/external/mit/xorg.
400:
1.197 mrg 401: 20090616:
402: Native Xorg was upgraded. Builds will need a clean objdir for
403: src/external/mit/xorg. Upgrading a system from sets will not
404: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
405: subdirectory has been changed into a file, and this needs to
406: be manually "rm -r"'ed before installing xbase.tgz.
407:
1.195 perry 408: 20090501:
409: Several new functions were added to string.h/libc, and this
410: can cause autoconf problems during the tool build for people
1.241 wiz 411: who fail to clean out their tools objects properly. If you

1.241 wiz 431: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
432: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 433: This is needed even in the MODULAR kernel because there is
434: conditionally compiled code in rtsock.c.
1.184 christos 435: 2. make sure build.sh completes and the binaries in a chroot work
436: before installing.
437: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 438: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 439: are installed properly, and start building libraries first libc
440: and libutil, install them and then continue building all the
1.241 wiz 441: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 442: the new libraries are installed, you can restart the build.
443: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 444: rebuild the required packages to update their shared libraries.
445: Any package you rebuild will require rebuilding all the packages
446: that depend on it.
1.186 christos 447: 5. Next time you run pwd_mkdb with the new binary, the file
448: will be upgraded and it will not be backwards compatible.
1.190 apb 449: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
450: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 451: for utmp. You are better off removing the old files after
1.190 apb 452: upgrading. The automated clearing of /var/run during
453: boot, and the automated rotating of files in /var/log by
454: newsyslog(8), may mean that you do not have to remove the
455: files manually.
456: 7. The optional accounting file (/var/account/acct, see
457: accton(8)) has not been versioned, and will need to be
458: removed. The automatic rotation of the accounting file by
459: /etc/daily limits the bad consequences of failure to remove
460: the file.
1.196 dholland 461: 8. Application software that writes time_t to binary files on
1.241 wiz 462: disk will break or need attention. Most notably: if you are
1.196 dholland 463: using PostgreSQL < 8.4, you need to dump your databases,

1.182 tsutsui 479: On i386, various kernel options(4) in GENERIC including
1.180 wiz 480: file systems have been disabled and moved into kernel modules.
481: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 482: following files as well as a new GENERIC kernel:
483:
484: - build and install kernel modules from src/sys/modules

1.180 wiz 487: for the file system from which the kernel is loaded automatically
1.179 tsutsui 488:
1.180 wiz 489: If you have to load your kernel from a file system which is not of
490: the same type as the root file system, you have to load the necessary

1.161 dsl 600: 20070422:

602: has been changed. Rather than modify the pathname (and copy back
603: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 604: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 605: root file system will be relative to that file system - unless they
1.161 dsl 606: start /../ this is useful when the emulated root is a real install

1.1 abs 680: Hints for a more successful build:
681: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 682: Use build.sh, but do not use its "expert mode":
1.132 jmmv 683: This will automatically build the tools in the
1.123 jmc 684: correct order, and it will keep the tools and the
685: new build products from interfering with the running
686: system. This will allow you to ignore most of the
687: other advice in this file.
1.2 mrg 688: Build a new kernel first:
689: This makes sure that any new system calls or features
690: expected by the new userland will be present. This
691: helps to avoid critical errors when upgrading.
1.1 abs 692: Use object directories:
693: This helps to keep stale object
694: files from polluting the build if a Makefile "forgets"
695: about one. It also makes it easier to clean up after
696: a build. It's also necessary if you want to use the
697: same source tree for multiple machines.
1.123 jmc 698: To use object directories with build.sh:
699: a) invoke build.sh with the "-M" or "-O" options.
700: To use object directories without using build.sh:
1.1 abs 701: a) cd /usr/src ; make cleandir
1.2 mrg 702: b) Add "OBJMACHINE=yes" to /etc/mk.conf
703: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 704: d) cd /usr/src ; make build
1.2 mrg 705: Note that running "make obj" in a directory will create
706: in obj.$MACHINE directory.
1.1 abs 707: Build to a DESTDIR:
1.123 jmc 708: This helps to keep old installed files (especially libraries)
709: from interfering with the new build.
710: To build to a DESTDIR with build.sh, use the "-D" option.
711: To build to a DESTDIR without using build.sh, set the DESTDIR
712: environment variable before running make build. It should be
713: set to the pathname of an initially empty directory.
714: Problems: if you do not use build.sh, you might need to
715: update critical utilities without using DESTDIR since
716: nothing is executed from what is installed in DESTDIR.
717: (See critical utils, below.)
1.1 abs 718: Build often:
719: This keeps critical utilities current enough to not choke

732:
733: Failsafe rebuild of a small part of the tree:
734: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
735: To make sure you rebuild something correctly you want to do
736: something like the following:
737: 1) Make sure the includes and .mk files are up to date.
738: 2) Make sure any program used to build the particular
739: utility is up to date. (yacc, lex, etc...)
740: 3) cd ...path/to/util...
741: make cleandir
742: rm ...all obj directories...
743: make cleandir # yes, again
744: make obj
745: make depend && make
746:
747: Failsafe rebuild of the entire tree:
748: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
749: If you really want to make sure the source tree is clean and

839: Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
840: No such file or directory.
841: Cause: If a directory is created by mistake, then it is sometimes
842: deleted from the CVS repository using administrative commands
843: that bypass the normal cvs access controls. If your cvs working tree
844: contains references to a directory that has been deleted on the
845: server in this way, then "cvs update" reports this error.
846: Fix: Recursively delete the affected directory from your working tree
847: and try the update again.
