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.

1.230 tls 21:
1.308 ! christos 22: 20200601:
! 23: Due to a mistake in LIBISPRIVATE handling, .so libraries were
! 24: created in the build directories and need cleaning.
! 25:
1.307 mrg 26: 20200311:
27: GCC 8 ports will need cleaning in src/tools/gcc and
28: src/external/gpl3/gcc due to GCC 8.4 update.
29:
1.306 christos 30: 20191118:
31: More architectures were switched to gcc8:
32: i386, ia64 powerpc64, sparc, sparc64, arm
33: The same comments as in 20191022 apply.
34:
1.305 martin 35: 20191112:
36: The LLVM update requires a clean rebuild for all architectures using
37: LLVM during the tools build phase (i386, amd64, aarch64).
38:
1.304 martin 39: 20191022:
40: Ports amd64 and aarch64 switched to GCC 8.3 by default.
41: In-place ("expert mode", build.sh -E) builds are not supported
42: when going from a GCC 7 userland to GCC 8. Do a regular
43: build to a different DESTDIR (or preferably: build.sh -U) at least
1.306 christos 44: once and install sets, or download comp.{tar.xz,tgz} from the
1.304 martin 45: daily builds and install that before doing the next in-place build.
46:
1.303 mrg 47: 20191001:
48: GCC 8.3 was imported. Builds of src/tools/gcc may fail if
49: old builds with GCC 7 output now uses GCC 8. Clean this
50: directory, and also clean src/external/gpl3/gcc.
51:
1.302 riastrad 52: 20190903:
1.306 christos 53: Files with names that coincide with existing files' names on
1.302 riastrad 54: case-insensitive file systems were inadvertently committed, for
55: radeon GPU firmware. We cannot mark these as obsolete for
56: postinstall to fix, so if you updated src since 2019-08-26, and
57: ran build.sh distribution or ran build.sh release, you must
58: manually delete the following files in your DESTDIR (which is
59: usually $OBJDIR/destir.$ARCH), or from / if you have installed
60: them:

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

1.241 wiz 578: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
579: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 580: This is needed even in the MODULAR kernel because there is
581: conditionally compiled code in rtsock.c.
1.184 christos 582: 2. make sure build.sh completes and the binaries in a chroot work
583: before installing.
584: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 585: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 586: are installed properly, and start building libraries first libc
587: and libutil, install them and then continue building all the
1.241 wiz 588: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 589: the new libraries are installed, you can restart the build.
590: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 591: rebuild the required packages to update their shared libraries.
592: Any package you rebuild will require rebuilding all the packages
593: that depend on it.
1.186 christos 594: 5. Next time you run pwd_mkdb with the new binary, the file
595: will be upgraded and it will not be backwards compatible.
1.190 apb 596: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
597: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 598: for utmp. You are better off removing the old files after
1.190 apb 599: upgrading. The automated clearing of /var/run during
600: boot, and the automated rotating of files in /var/log by
601: newsyslog(8), may mean that you do not have to remove the
602: files manually.
603: 7. The optional accounting file (/var/account/acct, see
604: accton(8)) has not been versioned, and will need to be
605: removed. The automatic rotation of the accounting file by
606: /etc/daily limits the bad consequences of failure to remove
607: the file.
1.196 dholland 608: 8. Application software that writes time_t to binary files on
1.241 wiz 609: disk will break or need attention. Most notably: if you are
1.196 dholland 610: using PostgreSQL < 8.4, you need to dump your databases,

617: config on all kernel configuration files before rebuilding those

811: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
812: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
813: kernel configuration for an example. X servers from the last
814: few years should cope.

1.1 abs 827: Hints for a more successful build:
828: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 829: Use build.sh, but do not use its "expert mode":
1.132 jmmv 830: This will automatically build the tools in the
1.123 jmc 831: correct order, and it will keep the tools and the
832: new build products from interfering with the running
833: system. This will allow you to ignore most of the
834: other advice in this file.
1.2 mrg 835: Build a new kernel first:
836: This makes sure that any new system calls or features
837: expected by the new userland will be present. This
838: helps to avoid critical errors when upgrading.
1.1 abs 839: Use object directories:
840: This helps to keep stale object
841: files from polluting the build if a Makefile "forgets"
842: about one. It also makes it easier to clean up after
843: a build. It's also necessary if you want to use the
844: same source tree for multiple machines.
1.123 jmc 845: To use object directories with build.sh:
846: a) invoke build.sh with the "-M" or "-O" options.
847: To use object directories without using build.sh:
1.1 abs 848: a) cd /usr/src ; make cleandir
1.2 mrg 849: b) Add "OBJMACHINE=yes" to /etc/mk.conf
850: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 851: d) cd /usr/src ; make build
1.2 mrg 852: Note that running "make obj" in a directory will create
853: in obj.$MACHINE directory.
1.1 abs 854: Build to a DESTDIR:
1.123 jmc 855: This helps to keep old installed files (especially libraries)
856: from interfering with the new build.
857: To build to a DESTDIR with build.sh, use the "-D" option.
858: To build to a DESTDIR without using build.sh, set the DESTDIR
859: environment variable before running make build. It should be
860: set to the pathname of an initially empty directory.
861: Problems: if you do not use build.sh, you might need to
862: update critical utilities without using DESTDIR since
863: nothing is executed from what is installed in DESTDIR.
864: (See critical utils, below.)
1.1 abs 865: Build often:
866: This keeps critical utilities current enough to not choke
867: on any other part of the source tree that depends on up to
1.123 jmc 868: date functionality. If you use build.sh, you should not have
869: this problem.
1.241 wiz 870:
1.1 abs 871: What to do if things don't work:
872: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 873: When things don't work there are usually a few things that commonly
1.1 abs 874: should be done.
875: 1) make includes
876: This should be done automatically by make build.
877: 2) cd share/mk && make install
878: Again, automatically done by make build.
879:
880: Failsafe rebuild of a small part of the tree:
881: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
882: To make sure you rebuild something correctly you want to do
883: something like the following:
884: 1) Make sure the includes and .mk files are up to date.
885: 2) Make sure any program used to build the particular
886: utility is up to date. (yacc, lex, etc...)
887: 3) cd ...path/to/util...
888: make cleandir
889: rm ...all obj directories...
890: make cleandir # yes, again
891: make obj
892: make depend && make
893:
894: Failsafe rebuild of the entire tree:
895: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
896: If you really want to make sure the source tree is clean and
1.2 mrg 897: ready for a build try the following. Note that sourcing /etc/mk.conf
898: (a make(1) Makefile) in this manner is not right, and will not work
899: for anyone who uses any make(1) features in /etc/mk.conf.

991: contains references to a directory that has been deleted on the

993: Fix: Recursively delete the affected directory from your working tree
994: and try the update again.
