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:
1.306 ! christos 22: 20191118:
! 23: More architectures were switched to gcc8:
! 24: i386, ia64 powerpc64, sparc, sparc64, arm
! 25: The same comments as in 20191022 apply.
! 26:
1.305 martin 27: 20191112:
28: The LLVM update requires a clean rebuild for all architectures using
29: LLVM during the tools build phase (i386, amd64, aarch64).
30:
1.304 martin 31: 20191022:
32: Ports amd64 and aarch64 switched to GCC 8.3 by default.
33: In-place ("expert mode", build.sh -E) builds are not supported
34: when going from a GCC 7 userland to GCC 8. Do a regular
35: build to a different DESTDIR (or preferably: build.sh -U) at least
1.306 ! christos 36: once and install sets, or download comp.{tar.xz,tgz} from the
1.304 martin 37: daily builds and install that before doing the next in-place build.
38:
1.303 mrg 39: 20191001:
40: GCC 8.3 was imported. Builds of src/tools/gcc may fail if
41: old builds with GCC 7 output now uses GCC 8. Clean this
42: directory, and also clean src/external/gpl3/gcc.
43:
1.302 riastrad 44: 20190903:
1.306 ! christos 45: Files with names that coincide with existing files' names on
1.302 riastrad 46: case-insensitive file systems were inadvertently committed, for
47: radeon GPU firmware. We cannot mark these as obsolete for
48: postinstall to fix, so if you updated src since 2019-08-26, and
49: ran build.sh distribution or ran build.sh release, you must
50: manually delete the following files in your DESTDIR (which is
51: usually $OBJDIR/destir.$ARCH), or from / if you have installed
52: them:

123:
1.301 martin 124: 20190727:
125: The uefi bootloader has gained tftp support and needs a clean
126: build. If you do update builds, manually clean its object
127: directory by something like:
128: cd sys/arch/i386/stand/efiboot && make clean
129:
1.300 martin 130: 20190723:
131: The jemalloc allocator in libc is now build without extended
132: debugging (for performance reasons). In update builds make sure
133: to rebuild it completly, by removing all affected object files,
134: including compat builds, something like:
135: cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
136:
1.299 mrg 137: 20190207:
138: GCC 7 switched for many ports. Update builds are likely to fail.
139:
1.298 martin 140: 20180924:
141: A newer OpenSSL version has been imported. If you are doing
142: update builds, make sure to remove all old obj dirs, like:
143: cd /usr/obj && find . -type d -name openssl | xargs rm -rf
144:
1.297 joerg 145: 20180717:
146: On aarch64 int64_t and related types have changed from long long
147: to long. This requires recompiling all C++ binaries.
148:
1.296 martin 149: 20180713:
150: On amd64 and i386 static binaries are now build position
151: independend. This requires recompilation of all object
152: files used to create the crunched /rescue binary.
153: Clean the rescue directory in your obj directory before
154: doing an update build, otherwise linking will fail.
155:
1.293 jakllsch 156: 20180414:
157: Existing binutils was migrated to binutils.old. Manual
158: removal of tools/binutils objects directory may be required
159: to fix tools build failure.
160:
1.292 mrg 161: 20180311:
162: bdftopcf was updated and may need cleaning in the
163: src/external/mit/xorg/tools/bdftopcf subdirectory if there are
164: link errors.
165:
1.291 mrg 166: 20180212:
167: between OpenSSL and GCC updates, many things may fail to build.
168: any failure that looks like GCC or openssl is best handled by
169: a clean destdir and objdir. Full cleandir and destdir deletion
170: is recommended if build failures occur.
171:
1.288 martin 172: 20171225:
173: removal of the vadvise syscall requires manual removal of all
174: associated files from the libc build object directory (including
1.289 christos 175: the .depend files) - a command like:
1.288 martin 176: cd $OBJ && find . -type d -name libc | xargs rm -rf
1.289 christos 177: For architectures that support multiple "compat" binary targets,
178: you'll need to cleanup both the regular libc directory and the
1.290 martin 179: compat ones (the above command will do that).
1.288 martin 180:
1.287 kre 181: 20171010:
182: a change to the build structure of external/bsd/acpica/bin/iasl
183: means that its objdir (or *.d and .depend at least) might need
184: to be manually removed - or a build done once without -u.
185:
1.286 mrg 186: 20170822:
187: a new version of GMP has been imported and probably
188: will break parts of builds related to themselves or GCC, both
189: in the tools and the native section. Remove all GCC, GMP, MPFR
190: and MPC objdirs or build once without -u.
191:
1.285 mrg 192: 20170816:
193: a new version of MPFR and MPC have been imported and probably
194: will break parts of builds related to themselves or GCC, both
195: in the tools and the native section. Remove all GCC, GMP, MPFR
196: and MPC objdirs or build once without -u.
197:
1.284 martin 198: 20170402:
199: a new version of dhcpcd has been imported, which does not support
200: update builds from the previous version. Remove your
201: external/bsd/dhcpcd object dir or build once without -u.
202:
1.281 roy 203: 20170211:
204: a new terminfo database has been imported.
205: The structure of it has changed slightly from prior versions and
206: an updated tic tool is required.
207: If you build.sh, don't use -u
208:
1.280 kre 209: 20170207:
1.278 kre 210: various arch dependent libc/exect.S files were removed
1.279 kre 211: Either remove the obj directories (lib/libc and compat/amd64/i386/lib
212: if it exists) or do a clean build.
213: (This is a bug in the make system, it should be corrected without
214: human intervention, but isn't.)
1.278 kre 215:
1.277 martin 216: 20170104:
217: xinput build options have changed.
218: Remove the obj directory (external/mit/xorg/bin/xinput)
219: if you build.sh -u
220:
1.276 martin 221: 20170103:
222: a new version of flex has been imported.
223: Remove the file from obj (external/bsd/flex)
224: if you build.sh -u
225:
1.275 spz 226: 20161014:
227: a new version of OpenSSL has been imported.
228: Remove the files from obj (crypto/external/bsd/openssl)
229: if you build.sh -u
230:
1.274 martin 231: 20161009:
232: a new version of dhcpcd has been imported with slightly changed
233: build infrastructure. When doing a build.sh -u this requires
234: pruning the external/bsd/dhcpcd objdir.
235:
1.273 mrg 236: 20160914:
237: i386, amd64, shark, ofppc and macppc have joined shark and x68k
238: ports in using xorg-server 1.18. This requires a clean destdir
239: and a clean objdir.
240:
1.272 dholland 241: 20160527:
242: i386 needs a full cleandir or objdir deletion because PIE has
243: been enabled. (see the amd64 entry two down for further info)
244:
1.270 christos 245: 20160418:
246: libedit needs manual removal of all autogenerated files since
1.271 christos 247: some of them are not autogenerated anymore. Remember that there
248: might be two copies of libedit if your platform builds "compat".
1.270 christos 249:
1.268 riastrad 250: 20160410:
251: amd64 needs full "make cleandir" or deletion of objdir now that
252: PIE has been enabled for amd64. PIE, or position-independent
253: executables, means all code, including executables and not just
254: shared libraries, is position-independent and hence able to be
255: relocated by ASLR, address space layout randomization.
256:
257: The change was made in Makefile variables for compiler and
258: linker flags, for which make(1) does not record dependencies,
259: hence it is unable to detect that all .o files need rebuilding.
260:
261: Partial rebuilds with some modified source files will likely
262: fail when linking executables, since the linker refuses to mix
263: position-independent code with position-dependent code in
264: position-independent executables:
265:
266: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
267:
1.267 mrg 268: 20160401:
269: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 270: Some people have found that cleandir is not sufficient, so if
271: in doubt delete the entire object directory tree for gcc.
1.267 mrg 272:
1.266 aymeric 273: 20160306:
1.265 aymeric 274: NetBSD's regexp implementation is now part of libnbcompat.
275: Nblex, nbm4, nbpax, nbsed use it and they may crash on
276: non-NetBSD hosts if linked with stale object files produced
277: while they included a non-NetBSD regex.h.
278: In any case, you should "make cleandir" at least these tools
279: before updating your toolchain.
280:
1.264 martin 281: 20160125:
282: Dtrace has been enabled by default on some architectures.
283: When doing an update build, make sure to clean the etc/mtree
284: object directory before starting the build - otherwise the
285: needed directories in destdir will not be created.
286: An easy way to do this is:
287: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
288:
1.263 dholland 289: 20150818:
290: New acpica requires "make cleandir" in src/external/bsd/acpica
291: again.
292:
1.262 christos 293: 20150413:
294: New acpica requires "make cleandir" and reinstalling yacc
295: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
296: also "make cleandir" in /usr/src/external/bsd/acpica.
297:
1.261 martin 298: 20150404:
299: Lint changes require a full rebuild of the tool, so make
300: sure to build without -u option to build.sh, or manually
301: do a make cleandir in src/tools/lint1 and
302: src/usr.bin/xlint.
303:
1.260 skrll 304: 20150310:
305: Improvements to openssl for arm mean that update builds of
306: the openssl libraries will fail. A make cleandir in
307: external/bsd/openssl/lib is needed
308:
1.258 martin 309: 20141026:
1.259 msaitoh 310: A mishap during the import of pppd may cause your corruption
1.258 martin 311: in your cvs directory if you happened to do a cvs update
312: during a short period of time. To fix, just remove the
313: directory src/external/bsd/ppp/dist/pppd completely
314: and let cvs restore it on next update.
315:
1.256 apb 316: 20140721:
317: The src/external/mit/lua/src directory was accidentally created
318: and then deleted in the CVS repository. If you get errors like
319:
320: cvs [update aborted]: cannot open directory
321: /cvsroot/src/external/mit/lua/src: No such file or directory
322:
323: then delete your local copy of that directory tree and try again.
324:
1.255 joerg 325: 20140530:
326: ARM eABI switched to DWARF based exception handling. This requires
327: rebuilding all C++ code. It is strongly advised to do a clean build.
328:
1.251 martin 329: 20140131:
1.253 joerg 330: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 331: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 332: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 333:
1.250 christos 334: 20131227:
335: 1. The new ntpd runs in a restricted mode to prevent amplification
336: attacks. If you need ntpdc to work you need to explicitly enable
337: mode7 in your config file. Make sure you put the necessary restrict
338: statements to avoid being exposed.
339: 2. strncat has moved from lib/libc to common/lib/libc; you might need
340: to make clean in libc
341:
1.249 mrg 342: 20131129:
343: The GMP sources were updated, and builds will likely fail without
344: cleaning their build trees for both tools and in-tree, like below.
345:
1.248 mrg 346: 20131128:
347: The MPC and MPFR sources were updated, and builds may require their
348: tools and in-tree directories cleaned for successful updates.
349:
1.246 martin 350: 20130605:
1.247 spz 351: The kernel option FAST_IPSEC no longer exists, it's been renamed
352: to IPSEC (and the older IPSEC version removed).
353:
354: 20130605:
1.246 martin 355: Previous freetype installations eroneously installed private
356: header files. If you are building against a non-empty $DESTDIR,
357: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
358:
1.245 mrg 359: 20130531:
360: The xdm update may cause build failure due to xdm.man being
361: in the obj tree. Make sure to ensure any like this:
362: nbmake: nbmake: don't know how to make xdm.man. Stop
363: is fixed by deleting the xdm.man in the obj tree.
364:
1.244 mrg 365: 20130530:
366: Updates of many xsrc packages will leave old .pc files around.
367: Best to clean out the xsrc objdir entirely before rebuilds.
368:
1.242 christos 369: 20130301:
370: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 371: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 372:
1.238 dholland 373: 20120726:
1.241 wiz 374: The update of OpenSSL requires cleaning both the OpenSSL build
375: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 376: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 377: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 378: cause third-party software to link incorrectly and/or crash.
1.238 dholland 379:
1.237 wiz 380: 20120507:
1.241 wiz 381: The database schema for makemandb was changed. You will
1.237 wiz 382: need to update the database using 'makemandb -f' or wait
383: for the next weekly run to fix it.
384:
1.236 bsh 385: 20120319:
386: sys/conf/Makefile.kern.inc has been modified to adjust the
387: size of db_symtab automatically. You need to update dbsym in
388: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
389: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
390: mk.conf.
391:
1.235 joerg 392: 20120216:
1.241 wiz 393: Default for MKCATPAGES changed to NO. Update builds will fail
394: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 395: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 396: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 397: the next run of weekly will fix it.
1.233 joerg 398:
1.232 christos 399: 20111227:
400: If you built between 20111225 and 20111227 you need to remove
401: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
402: bump has been reverted.
403:
1.231 tls 404: 20111125:
405: The "rnd" pseudodevice has been added to sys/conf/std, which
406: means it should no longer be explicitly listed in kernel
407: configuration files. The line "pseudo-device rnd" should be
408: removed from any custom kernel config files users may have.
409:
1.230 tls 410: 20111119:
411: A problem with the datastructures used by the rndctl(8)
412: utility (pointers in datastructures in an array, making 32->64
413: bit compatibility very painful) has been fixed in a
414: non-backwards-compatible way. If you replace your kernel,

1.241 wiz 438: The layout of external/public-domain/xz has changed. To do an
1.225 matt 439: update build you will have to remove the contents of the OBJDIR
440: for external/public-domain/xz/bin by hand as the xz entry there
441: is now a directory.

1.222 plunky 451: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86

1.221 lukem 456: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 457: the build of individual parts of the tree. This is handled

1.241 wiz 468: variables with names that contain '='. Revision 1.18 of env.c
469: assumed that this was allowed. Installing a new libc with an
1.216 christos 470: old copy of /usr/bin/env causes env x=1 printenv | grep x= to

1.241 wiz 570: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
571: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 572: This is needed even in the MODULAR kernel because there is
573: conditionally compiled code in rtsock.c.
1.184 christos 574: 2. make sure build.sh completes and the binaries in a chroot work
575: before installing.
576: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 577: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 578: are installed properly, and start building libraries first libc
579: and libutil, install them and then continue building all the
1.241 wiz 580: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 581: the new libraries are installed, you can restart the build.
582: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 583: rebuild the required packages to update their shared libraries.
584: Any package you rebuild will require rebuilding all the packages
585: that depend on it.
1.186 christos 586: 5. Next time you run pwd_mkdb with the new binary, the file
587: will be upgraded and it will not be backwards compatible.
1.190 apb 588: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
589: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 590: for utmp. You are better off removing the old files after
1.190 apb 591: upgrading. The automated clearing of /var/run during
592: boot, and the automated rotating of files in /var/log by
593: newsyslog(8), may mean that you do not have to remove the
594: files manually.
595: 7. The optional accounting file (/var/account/acct, see
596: accton(8)) has not been versioned, and will need to be
597: removed. The automatic rotation of the accounting file by
598: /etc/daily limits the bad consequences of failure to remove
599: the file.
1.196 dholland 600: 8. Application software that writes time_t to binary files on
1.241 wiz 601: disk will break or need attention. Most notably: if you are
1.196 dholland 602: using PostgreSQL < 8.4, you need to dump your databases,

606: config(1) has been updated, and one of the files it creates -
607: swapnetbsd.o - has changed format. You need to rebuild config
608: (done automatically by build.sh) and then you need to rerun
609: config on all kernel configuration files before rebuilding those
610: kernels.

1.181 cube 612: 20081205:
613: If you build with MKX11=no, you should remove /etc/rc.d/xdm and

1.179 tsutsui 631:
1.178 lukem 632: 20080827:
633: If you built and installed a libc from sources between

635: which results in false errors reported by lint(1).
636: Since this breaks the libc build itself, manual help is
1.180 wiz 637: needed -- lint must be disabled temporarily, e.g.:

741: has been changed. Rather than modify the pathname (and copy back
742: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 743: root. One side effect is that absolute symlinks inside the emulated

1.1 abs 819: Hints for a more successful build:
820: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 821: Use build.sh, but do not use its "expert mode":
1.132 jmmv 822: This will automatically build the tools in the
1.123 jmc 823: correct order, and it will keep the tools and the
824: new build products from interfering with the running
825: system. This will allow you to ignore most of the
826: other advice in this file.
1.2 mrg 827: Build a new kernel first:
828: This makes sure that any new system calls or features
829: expected by the new userland will be present. This
830: helps to avoid critical errors when upgrading.
1.1 abs 831: Use object directories:
832: This helps to keep stale object
833: files from polluting the build if a Makefile "forgets"
834: about one. It also makes it easier to clean up after
835: a build. It's also necessary if you want to use the
836: same source tree for multiple machines.
1.123 jmc 837: To use object directories with build.sh:
838: a) invoke build.sh with the "-M" or "-O" options.
839: To use object directories without using build.sh:
1.1 abs 840: a) cd /usr/src ; make cleandir
1.2 mrg 841: b) Add "OBJMACHINE=yes" to /etc/mk.conf
842: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 843: d) cd /usr/src ; make build
1.2 mrg 844: Note that running "make obj" in a directory will create
845: in obj.$MACHINE directory.
1.1 abs 846: Build to a DESTDIR:
1.123 jmc 847: This helps to keep old installed files (especially libraries)
848: from interfering with the new build.
849: To build to a DESTDIR with build.sh, use the "-D" option.
850: To build to a DESTDIR without using build.sh, set the DESTDIR
851: environment variable before running make build. It should be
852: set to the pathname of an initially empty directory.
853: Problems: if you do not use build.sh, you might need to
854: update critical utilities without using DESTDIR since
855: nothing is executed from what is installed in DESTDIR.
856: (See critical utils, below.)
1.1 abs 857: Build often:
858: This keeps critical utilities current enough to not choke
859: on any other part of the source tree that depends on up to
1.123 jmc 860: date functionality. If you use build.sh, you should not have
861: this problem.

1.1 abs 863: What to do if things don't work:
864: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 865: When things don't work there are usually a few things that commonly
1.1 abs 866: should be done.
867: 1) make includes
868: This should be done automatically by make build.
869: 2) cd share/mk && make install
870: Again, automatically done by make build.
871:
872: Failsafe rebuild of a small part of the tree:
873: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
874: To make sure you rebuild something correctly you want to do
875: something like the following:
876: 1) Make sure the includes and .mk files are up to date.
877: 2) Make sure any program used to build the particular
878: utility is up to date. (yacc, lex, etc...)
879: 3) cd ...path/to/util...
880: make cleandir
881: rm ...all obj directories...
882: make cleandir # yes, again
883: make obj
884: make depend && make
885:
886: Failsafe rebuild of the entire tree:
887: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
888: If you really want to make sure the source tree is clean and
1.2 mrg 889: ready for a build try the following. Note that sourcing /etc/mk.conf
890: (a make(1) Makefile) in this manner is not right, and will not work
891: for anyone who uses any make(1) features in /etc/mk.conf.

978: Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
979: No such file or directory.
980: Cause: If a directory is created by mistake, then it is sometimes
981: deleted from the CVS repository using administrative commands
982: that bypass the normal cvs access controls. If your cvs working tree
983: contains references to a directory that has been deleted on the
984: server in this way, then "cvs update" reports this error.
985: Fix: Recursively delete the affected directory from your working tree
986: and try the update again.
