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:
1.275 ! spz 22: 20161014:
! 23: a new version of OpenSSL has been imported.
! 24: Remove the files from obj (crypto/external/bsd/openssl)
! 25: if you build.sh -u
! 26:
1.274 martin 27: 20161009:
28: a new version of dhcpcd has been imported with slightly changed
29: build infrastructure. When doing a build.sh -u this requires
30: pruning the external/bsd/dhcpcd objdir.
31:
1.273 mrg 32: 20160914:
33: i386, amd64, shark, ofppc and macppc have joined shark and x68k
34: ports in using xorg-server 1.18. This requires a clean destdir
35: and a clean objdir.
36:
1.272 dholland 37: 20160527:
38: i386 needs a full cleandir or objdir deletion because PIE has
39: been enabled. (see the amd64 entry two down for further info)
40:
1.270 christos 41: 20160418:
42: libedit needs manual removal of all autogenerated files since
1.271 christos 43: some of them are not autogenerated anymore. Remember that there
44: might be two copies of libedit if your platform builds "compat".
1.270 christos 45:
1.268 riastrad 46: 20160410:
47: amd64 needs full "make cleandir" or deletion of objdir now that
48: PIE has been enabled for amd64. PIE, or position-independent
49: executables, means all code, including executables and not just
50: shared libraries, is position-independent and hence able to be
51: relocated by ASLR, address space layout randomization.
52:
53: The change was made in Makefile variables for compiler and
54: linker flags, for which make(1) does not record dependencies,
55: hence it is unable to detect that all .o files need rebuilding.
56:
57: Partial rebuilds with some modified source files will likely
58: fail when linking executables, since the linker refuses to mix
59: position-independent code with position-dependent code in
60: position-independent executables:
61:
62: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
63:
1.267 mrg 64: 20160401:
65: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 66: Some people have found that cleandir is not sufficient, so if
67: in doubt delete the entire object directory tree for gcc.
1.267 mrg 68:
1.266 aymeric 69: 20160306:
1.265 aymeric 70: NetBSD's regexp implementation is now part of libnbcompat.
71: Nblex, nbm4, nbpax, nbsed use it and they may crash on
72: non-NetBSD hosts if linked with stale object files produced
73: while they included a non-NetBSD regex.h.
74: In any case, you should "make cleandir" at least these tools
75: before updating your toolchain.
76:
1.264 martin 77: 20160125:
78: Dtrace has been enabled by default on some architectures.
79: When doing an update build, make sure to clean the etc/mtree
80: object directory before starting the build - otherwise the
81: needed directories in destdir will not be created.
82: An easy way to do this is:
83: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
84:
1.263 dholland 85: 20150818:
86: New acpica requires "make cleandir" in src/external/bsd/acpica
87: again.
88:
1.262 christos 89: 20150413:
90: New acpica requires "make cleandir" and reinstalling yacc
91: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
92: also "make cleandir" in /usr/src/external/bsd/acpica.
93:
1.261 martin 94: 20150404:
95: Lint changes require a full rebuild of the tool, so make
96: sure to build without -u option to build.sh, or manually
97: do a make cleandir in src/tools/lint1 and
98: src/usr.bin/xlint.
99:
1.260 skrll 100: 20150310:
101: Improvements to openssl for arm mean that update builds of
102: the openssl libraries will fail. A make cleandir in
103: external/bsd/openssl/lib is needed
104:
1.258 martin 105: 20141026:
1.259 msaitoh 106: A mishap during the import of pppd may cause your corruption
1.258 martin 107: in your cvs directory if you happened to do a cvs update
108: during a short period of time. To fix, just remove the
109: directory src/external/bsd/ppp/dist/pppd completely
110: and let cvs restore it on next update.
111:
1.256 apb 112: 20140721:
113: The src/external/mit/lua/src directory was accidentally created
114: and then deleted in the CVS repository. If you get errors like
115:
116: cvs [update aborted]: cannot open directory
117: /cvsroot/src/external/mit/lua/src: No such file or directory
118:
119: then delete your local copy of that directory tree and try again.
120:
1.255 joerg 121: 20140530:
122: ARM eABI switched to DWARF based exception handling. This requires
123: rebuilding all C++ code. It is strongly advised to do a clean build.
124:
1.251 martin 125: 20140131:
1.253 joerg 126: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 127: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 128: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 129:
1.250 christos 130: 20131227:
131: 1. The new ntpd runs in a restricted mode to prevent amplification
132: attacks. If you need ntpdc to work you need to explicitly enable
133: mode7 in your config file. Make sure you put the necessary restrict
134: statements to avoid being exposed.
135: 2. strncat has moved from lib/libc to common/lib/libc; you might need
136: to make clean in libc
137:
1.249 mrg 138: 20131129:
139: The GMP sources were updated, and builds will likely fail without
140: cleaning their build trees for both tools and in-tree, like below.
141:
1.248 mrg 142: 20131128:
143: The MPC and MPFR sources were updated, and builds may require their
144: tools and in-tree directories cleaned for successful updates.
145:
1.246 martin 146: 20130605:
1.247 spz 147: The kernel option FAST_IPSEC no longer exists, it's been renamed
148: to IPSEC (and the older IPSEC version removed).
149:
150: 20130605:
1.246 martin 151: Previous freetype installations eroneously installed private
152: header files. If you are building against a non-empty $DESTDIR,
153: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
154:
1.245 mrg 155: 20130531:
156: The xdm update may cause build failure due to xdm.man being
157: in the obj tree. Make sure to ensure any like this:
158: nbmake: nbmake: don't know how to make xdm.man. Stop
159: is fixed by deleting the xdm.man in the obj tree.
160:
1.244 mrg 161: 20130530:
162: Updates of many xsrc packages will leave old .pc files around.
163: Best to clean out the xsrc objdir entirely before rebuilds.
164:
1.242 christos 165: 20130301:
166: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 167: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 168:
1.238 dholland 169: 20120726:
1.241 wiz 170: The update of OpenSSL requires cleaning both the OpenSSL build
171: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 172: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 173: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 174: cause third-party software to link incorrectly and/or crash.
1.238 dholland 175:
1.237 wiz 176: 20120507:
1.241 wiz 177: The database schema for makemandb was changed. You will
1.237 wiz 178: need to update the database using 'makemandb -f' or wait
179: for the next weekly run to fix it.
180:
1.236 bsh 181: 20120319:
182: sys/conf/Makefile.kern.inc has been modified to adjust the
183: size of db_symtab automatically. You need to update dbsym in
184: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
185: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
186: mk.conf.
187:
1.235 joerg 188: 20120216:
1.241 wiz 189: Default for MKCATPAGES changed to NO. Update builds will fail
190: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 191: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 192: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 193: the next run of weekly will fix it.
1.233 joerg 194:
1.232 christos 195: 20111227:
196: If you built between 20111225 and 20111227 you need to remove
197: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
198: bump has been reverted.
199:
1.231 tls 200: 20111125:
201: The "rnd" pseudodevice has been added to sys/conf/std, which
202: means it should no longer be explicitly listed in kernel
203: configuration files. The line "pseudo-device rnd" should be
204: removed from any custom kernel config files users may have.
205:
1.230 tls 206: 20111119:
207: A problem with the datastructures used by the rndctl(8)
208: utility (pointers in datastructures in an array, making 32->64
209: bit compatibility very painful) has been fixed in a
210: non-backwards-compatible way. If you replace your kernel,
211: replace your rndctl executable too.
1.241 wiz 212:
1.229 jym 213: 20111001:
214: the prop_*_send_syscall() functions from proplib(3) have been
215: changed and their new version is not backward compatible with the old
1.241 wiz 216: one. So ensure that all consumers of these functions (currently:
1.229 jym 217: quota2 code and its tests) are updated together with the new lib.
218:
1.228 mrg 219: 20110817:
220: sparc has been changed to use GCC 4.5.3, so any objdir or
221: DESTDIR for them should be deleted before updating.
222:
1.227 riastrad 223: 20110806:
224: i386 and amd64 have been changed to use GCC 4.5.3, so any
225: objdir or DESTDIR for them should be deleted before updating.
226:
1.226 mrg 227: 20110805:
228: The update to GCC 4.5.3 requires a non-trivial portion of
229: the tree to be cleaned. Best to delete both objdir and
230: DESTDIR before running this update. So far, only the
231: sparc64, mips and powerpc platforms have changed.
232:
1.225 matt 233: 20110803:
1.241 wiz 234: The layout of external/public-domain/xz has changed. To do an
1.225 matt 235: update build you will have to remove the contents of the OBJDIR
236: for external/public-domain/xz/bin by hand as the xz entry there
237: is now a directory.
238:
1.223 joerg 239: 20110410:
1.241 wiz 240: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 241: update build you have to clean both tools/binutils and
242: tools/gcc by hand.
1.223 joerg 243:
1.222 plunky 244: 20110328:
245: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 246: ordering issues with "make all". It may be necessary to remove
1.222 plunky 247: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
248: if your update build fails, as the "Xorg" entry there is now a
249: directory.
250:
1.220 joerg 251: 20110121:
1.221 lukem 252: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 253: the build of individual parts of the tree. This is handled
254: correctly by build.sh. Manual builds have to update /usr/share/mk
255: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 256:
1.217 jruoho 257: 20101217:
258: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 259: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 260: group(5) in order to make the program work with existing setups.
261:
1.216 christos 262: 20101125:
263: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 264: variables with names that contain '='. Revision 1.18 of env.c
265: assumed that this was allowed. Installing a new libc with an
1.216 christos 266: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
267: break which affects the autoconf tests for dependency finding,
268: so building gcc will end up printing:
269: checking dependency style of gcc... none
270: configure: error: no usable dependency style found
271: Fix it by rebuilding and re-installing env.
1.138 lukem 272:
1.215 mrg 273: 20101119:
274: Recent Xorg updates in xsrc/external/mit/ may cause various build
275: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
276: have any build problems with xsrc, or problems with mismatched
277: versions between xorg-server and drivers.
278:
1.213 jmmv 279: 20100604:
280: The update of ATF to 0.9 causes old tests written in shell to fail
281: unless they are rebuilt. If you are building with MKUPDATE=yes,
282: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
283: trees by hand.
284:
1.211 tnozaki 285: 20100522:
1.212 mrg 286: Recent Xorg updates in xsrc/external/mit/ will cause various build
287: problems. Delete your entire DESTDIR and OBJDIR if you have any
288: build problems with xsrc.
289:
290: 20100522:
1.211 tnozaki 291: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 292: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 293:
1.210 christos 294: 20100520:
1.241 wiz 295: The location of the xkb compiled descriptions has changed. Please
1.210 christos 296: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
297:
1.209 njoly 298: 20100222:
299: The shared objects file extension has been changed from .so to
300: .pico, in order to avoid conflicts with shared libraries names
301: libXX.so. All now stale regular .so files can be removed from
302: your object directories.
303:
1.208 roy 304: 20100204:
305: The termcap database has been removed from the sources,
306: but has not been marked obsolete so it is not removed
307: from the system when upgrading.
308: As such, you will need to remove them from your object
309: and destination directories.
310:
1.203 dyoung 311: 20091101:
1.205 dholland 312: After updating, it may be necessary to make the 'cleandir'
313: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
314: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
315: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 316:
1.202 mrg 317: 20091001:
1.206 dholland 318: On amd64 you must rebuild tools (to get the new binutils)
319: before building a kernel, or the build fails on cpufunc.S.
320:
321: 20091001:
1.202 mrg 322: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
323: symlink, failing the build. Delete the link, and the subdir
324: it is in, and retry your build.
325:
1.201 dsl 326: 20090718:
327: libc build changed so that strchr() provides the extra entry
1.241 wiz 328: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 329: may fail because the archive contains the unwanted index.o.
330: (Similarly for strrchr() and rindex().)
331:
1.198 mrg 332: 20090709:
333: Native Xorg was upgraded again. Builds will probably fail again
334: without a clean objdir, at least for src/external/mit/xorg.
335:
1.197 mrg 336: 20090616:
337: Native Xorg was upgraded. Builds will need a clean objdir for
338: src/external/mit/xorg. Upgrading a system from sets will not
339: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
340: subdirectory has been changed into a file, and this needs to
341: be manually "rm -r"'ed before installing xbase.tgz.
342:
1.195 perry 343: 20090501:
344: Several new functions were added to string.h/libc, and this
345: can cause autoconf problems during the tool build for people
1.241 wiz 346: who fail to clean out their tools objects properly. If you
1.195 perry 347: note messages about stpcpy, stpncpy or strnlen accompanying a
348: failure during the tool build, clean out all your tools
349: objects and start again.
350:
1.194 mrg 351: 20090325:
352: The i386 port was switched to i486 default toolchain. This requires
353: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
354:
1.192 skrll 355: 20090126:
1.241 wiz 356: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 357: need to 'rm -f __posix_fadvise50.*' in the libc build directory
358: to avoid using the old assembly stub.
1.192 skrll 359:
1.191 joerg 360: 20090202:
361: pkg_install now depends on the pkgdb cache for automatic conflict
362: detection. It is recommented to rebuild the cache with
363: ``pkg_admin rebuild''.
364:
1.184 christos 365: 20090110:
1.241 wiz 366: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
367: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 368: This is needed even in the MODULAR kernel because there is
369: conditionally compiled code in rtsock.c.
1.184 christos 370: 2. make sure build.sh completes and the binaries in a chroot work
371: before installing.
372: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 373: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 374: are installed properly, and start building libraries first libc
375: and libutil, install them and then continue building all the
1.241 wiz 376: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 377: the new libraries are installed, you can restart the build.
378: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 379: rebuild the required packages to update their shared libraries.
380: Any package you rebuild will require rebuilding all the packages
381: that depend on it.
1.186 christos 382: 5. Next time you run pwd_mkdb with the new binary, the file
383: will be upgraded and it will not be backwards compatible.
1.190 apb 384: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
385: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 386: for utmp. You are better off removing the old files after
1.190 apb 387: upgrading. The automated clearing of /var/run during
388: boot, and the automated rotating of files in /var/log by
389: newsyslog(8), may mean that you do not have to remove the
390: files manually.
391: 7. The optional accounting file (/var/account/acct, see
392: accton(8)) has not been versioned, and will need to be
393: removed. The automatic rotation of the accounting file by
394: /etc/daily limits the bad consequences of failure to remove
395: the file.
1.196 dholland 396: 8. Application software that writes time_t to binary files on
1.241 wiz 397: disk will break or need attention. Most notably: if you are
1.196 dholland 398: using PostgreSQL < 8.4, you need to dump your databases,
399: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 400:
1.183 pgoyette 401: 20081219:

1.182 tsutsui 414: On i386, various kernel options(4) in GENERIC including
1.180 wiz 415: file systems have been disabled and moved into kernel modules.
416: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 417: following files as well as a new GENERIC kernel:
418:

420:
421: - install the latest bootloader, which will load a module
1.180 wiz 422: for the file system from which the kernel is loaded automatically
1.179 tsutsui 423:
1.180 wiz 424: If you have to load your kernel from a file system which is not of
425: the same type as the root file system, you have to load the necessary
426: file system module manually on the boot prompt or in the boot.cfg file.

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

1.161 dsl 535: 20070422:
536: The way OS emulations lookup filenames inside the emulation root
537: has been changed. Rather than modify the pathname (and copy back
538: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 539: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 540: root file system will be relative to that file system - unless they
1.161 dsl 541: start /../ this is useful when the emulated root is a real install

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

1.1 abs 615: Hints for a more successful build:
616: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 617: Use build.sh, but do not use its "expert mode":
1.132 jmmv 618: This will automatically build the tools in the
1.123 jmc 619: correct order, and it will keep the tools and the
620: new build products from interfering with the running
621: system. This will allow you to ignore most of the
622: other advice in this file.
1.2 mrg 623: Build a new kernel first:
624: This makes sure that any new system calls or features
625: expected by the new userland will be present. This
626: helps to avoid critical errors when upgrading.
1.1 abs 627: Use object directories:
628: This helps to keep stale object
629: files from polluting the build if a Makefile "forgets"
630: about one. It also makes it easier to clean up after
631: a build. It's also necessary if you want to use the
632: same source tree for multiple machines.
1.123 jmc 633: To use object directories with build.sh:
634: a) invoke build.sh with the "-M" or "-O" options.
635: To use object directories without using build.sh:
1.1 abs 636: a) cd /usr/src ; make cleandir
1.2 mrg 637: b) Add "OBJMACHINE=yes" to /etc/mk.conf
638: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 639: d) cd /usr/src ; make build
1.2 mrg 640: Note that running "make obj" in a directory will create
641: in obj.$MACHINE directory.
1.1 abs 642: Build to a DESTDIR:
1.123 jmc 643: This helps to keep old installed files (especially libraries)
644: from interfering with the new build.
645: To build to a DESTDIR with build.sh, use the "-D" option.
646: To build to a DESTDIR without using build.sh, set the DESTDIR
647: environment variable before running make build. It should be
648: set to the pathname of an initially empty directory.
649: Problems: if you do not use build.sh, you might need to
650: update critical utilities without using DESTDIR since
651: nothing is executed from what is installed in DESTDIR.
652: (See critical utils, below.)
1.1 abs 653: Build often:
654: This keeps critical utilities current enough to not choke
655: on any other part of the source tree that depends on up to
1.123 jmc 656: date functionality. If you use build.sh, you should not have
657: this problem.

1.230 tls 661: When things don't work there are usually a few things that commonly

665: 2) cd share/mk && make install
666: Again, automatically done by make build.
667:
668: Failsafe rebuild of a small part of the tree:
669: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
670: To make sure you rebuild something correctly you want to do
671: something like the following:
672: 1) Make sure the includes and .mk files are up to date.
673: 2) Make sure any program used to build the particular
674: utility is up to date. (yacc, lex, etc...)
675: 3) cd ...path/to/util...
676: make cleandir
677: rm ...all obj directories...
678: make cleandir # yes, again
679: make obj
680: make depend && make
681:
682: Failsafe rebuild of the entire tree:
683: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
684: If you really want to make sure the source tree is clean and
1.2 mrg 685: ready for a build try the following. Note that sourcing /etc/mk.conf
