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:
1.282 ! kamil 22: 20170217:
! 23: TRAP_HWWPT renamed to TRAP_DBREG, remove obj copy of siginfo.c
! 24: (usr.bin/kdump/siginfo.c and rescue/kdump/siginfo.c) to regenerate
! 25: if you build.sh -u
! 26:
1.281 roy 27: 20170211:
28: a new terminfo database has been imported.
29: The structure of it has changed slightly from prior versions and
30: an updated tic tool is required.
31: If you build.sh, don't use -u
32:
1.280 kre 33: 20170207:
1.278 kre 34: various arch dependent libc/exect.S files were removed
1.279 kre 35: Either remove the obj directories (lib/libc and compat/amd64/i386/lib
36: if it exists) or do a clean build.
37: (This is a bug in the make system, it should be corrected without
38: human intervention, but isn't.)
1.278 kre 39:
1.277 martin 40: 20170104:
41: xinput build options have changed.
42: Remove the obj directory (external/mit/xorg/bin/xinput)
43: if you build.sh -u
44:
1.276 martin 45: 20170103:
46: a new version of flex has been imported.
47: Remove the file from obj (external/bsd/flex)
48: if you build.sh -u
49:
1.275 spz 50: 20161014:
51: a new version of OpenSSL has been imported.
52: Remove the files from obj (crypto/external/bsd/openssl)
53: if you build.sh -u
54:
1.274 martin 55: 20161009:
56: a new version of dhcpcd has been imported with slightly changed
57: build infrastructure. When doing a build.sh -u this requires
58: pruning the external/bsd/dhcpcd objdir.
59:
1.273 mrg 60: 20160914:
61: i386, amd64, shark, ofppc and macppc have joined shark and x68k
62: ports in using xorg-server 1.18. This requires a clean destdir
63: and a clean objdir.
64:
1.272 dholland 65: 20160527:
66: i386 needs a full cleandir or objdir deletion because PIE has
67: been enabled. (see the amd64 entry two down for further info)
68:
1.270 christos 69: 20160418:
70: libedit needs manual removal of all autogenerated files since
1.271 christos 71: some of them are not autogenerated anymore. Remember that there
72: might be two copies of libedit if your platform builds "compat".
1.270 christos 73:
1.268 riastrad 74: 20160410:
75: amd64 needs full "make cleandir" or deletion of objdir now that
76: PIE has been enabled for amd64. PIE, or position-independent
77: executables, means all code, including executables and not just
78: shared libraries, is position-independent and hence able to be
79: relocated by ASLR, address space layout randomization.
80:
81: The change was made in Makefile variables for compiler and
82: linker flags, for which make(1) does not record dependencies,
83: hence it is unable to detect that all .o files need rebuilding.
84:
85: Partial rebuilds with some modified source files will likely
86: fail when linking executables, since the linker refuses to mix
87: position-independent code with position-dependent code in
88: position-independent executables:
89:
90: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
91:
1.267 mrg 92: 20160401:
93: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 94: Some people have found that cleandir is not sufficient, so if
95: in doubt delete the entire object directory tree for gcc.
1.267 mrg 96:
1.266 aymeric 97: 20160306:
1.265 aymeric 98: NetBSD's regexp implementation is now part of libnbcompat.
99: Nblex, nbm4, nbpax, nbsed use it and they may crash on
100: non-NetBSD hosts if linked with stale object files produced
101: while they included a non-NetBSD regex.h.
102: In any case, you should "make cleandir" at least these tools
103: before updating your toolchain.
104:
1.264 martin 105: 20160125:
106: Dtrace has been enabled by default on some architectures.
107: When doing an update build, make sure to clean the etc/mtree
108: object directory before starting the build - otherwise the
109: needed directories in destdir will not be created.
110: An easy way to do this is:
111: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
112:
1.263 dholland 113: 20150818:
114: New acpica requires "make cleandir" in src/external/bsd/acpica
115: again.
116:
1.262 christos 117: 20150413:
118: New acpica requires "make cleandir" and reinstalling yacc
119: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
120: also "make cleandir" in /usr/src/external/bsd/acpica.
121:
1.261 martin 122: 20150404:
123: Lint changes require a full rebuild of the tool, so make
124: sure to build without -u option to build.sh, or manually
125: do a make cleandir in src/tools/lint1 and
126: src/usr.bin/xlint.
127:
1.260 skrll 128: 20150310:
129: Improvements to openssl for arm mean that update builds of
130: the openssl libraries will fail. A make cleandir in
131: external/bsd/openssl/lib is needed
132:
1.258 martin 133: 20141026:
1.259 msaitoh 134: A mishap during the import of pppd may cause your corruption
1.258 martin 135: in your cvs directory if you happened to do a cvs update
136: during a short period of time. To fix, just remove the
137: directory src/external/bsd/ppp/dist/pppd completely
138: and let cvs restore it on next update.
139:
1.256 apb 140: 20140721:
141: The src/external/mit/lua/src directory was accidentally created
142: and then deleted in the CVS repository. If you get errors like
143:
144: cvs [update aborted]: cannot open directory
145: /cvsroot/src/external/mit/lua/src: No such file or directory
146:
147: then delete your local copy of that directory tree and try again.
148:
1.255 joerg 149: 20140530:
150: ARM eABI switched to DWARF based exception handling. This requires
151: rebuilding all C++ code. It is strongly advised to do a clean build.
152:
1.251 martin 153: 20140131:
1.253 joerg 154: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 155: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 156: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 157:
1.250 christos 158: 20131227:
159: 1. The new ntpd runs in a restricted mode to prevent amplification
160: attacks. If you need ntpdc to work you need to explicitly enable
161: mode7 in your config file. Make sure you put the necessary restrict
162: statements to avoid being exposed.
163: 2. strncat has moved from lib/libc to common/lib/libc; you might need
164: to make clean in libc
165:
1.249 mrg 166: 20131129:
167: The GMP sources were updated, and builds will likely fail without
168: cleaning their build trees for both tools and in-tree, like below.
169:
1.248 mrg 170: 20131128:
171: The MPC and MPFR sources were updated, and builds may require their
172: tools and in-tree directories cleaned for successful updates.
173:
1.246 martin 174: 20130605:
1.247 spz 175: The kernel option FAST_IPSEC no longer exists, it's been renamed
176: to IPSEC (and the older IPSEC version removed).
177:
178: 20130605:
1.246 martin 179: Previous freetype installations eroneously installed private
180: header files. If you are building against a non-empty $DESTDIR,
181: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
182:
1.245 mrg 183: 20130531:
184: The xdm update may cause build failure due to xdm.man being
185: in the obj tree. Make sure to ensure any like this:
186: nbmake: nbmake: don't know how to make xdm.man. Stop
187: is fixed by deleting the xdm.man in the obj tree.
188:
1.244 mrg 189: 20130530:
190: Updates of many xsrc packages will leave old .pc files around.
191: Best to clean out the xsrc objdir entirely before rebuilds.
192:
1.242 christos 193: 20130301:
194: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 195: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 196:
1.238 dholland 197: 20120726:
1.241 wiz 198: The update of OpenSSL requires cleaning both the OpenSSL build
199: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 200: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 201: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 202: cause third-party software to link incorrectly and/or crash.
1.238 dholland 203:
1.237 wiz 204: 20120507:
1.241 wiz 205: The database schema for makemandb was changed. You will
1.237 wiz 206: need to update the database using 'makemandb -f' or wait
207: for the next weekly run to fix it.
208:
1.236 bsh 209: 20120319:
210: sys/conf/Makefile.kern.inc has been modified to adjust the
211: size of db_symtab automatically. You need to update dbsym in
212: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
213: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
214: mk.conf.
215:
1.235 joerg 216: 20120216:
1.241 wiz 217: Default for MKCATPAGES changed to NO. Update builds will fail
218: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 219: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 220: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 221: the next run of weekly will fix it.
1.233 joerg 222:
1.232 christos 223: 20111227:
224: If you built between 20111225 and 20111227 you need to remove
225: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
226: bump has been reverted.
227:
1.231 tls 228: 20111125:
229: The "rnd" pseudodevice has been added to sys/conf/std, which
230: means it should no longer be explicitly listed in kernel
231: configuration files. The line "pseudo-device rnd" should be
232: removed from any custom kernel config files users may have.
233:
1.230 tls 234: 20111119:
235: A problem with the datastructures used by the rndctl(8)
236: utility (pointers in datastructures in an array, making 32->64
237: bit compatibility very painful) has been fixed in a
238: non-backwards-compatible way. If you replace your kernel,
239: replace your rndctl executable too.
1.241 wiz 240:
1.229 jym 241: 20111001:
242: the prop_*_send_syscall() functions from proplib(3) have been
243: changed and their new version is not backward compatible with the old
1.241 wiz 244: one. So ensure that all consumers of these functions (currently:
1.229 jym 245: quota2 code and its tests) are updated together with the new lib.
246:
1.228 mrg 247: 20110817:
248: sparc has been changed to use GCC 4.5.3, so any objdir or
249: DESTDIR for them should be deleted before updating.
250:
1.227 riastrad 251: 20110806:
252: i386 and amd64 have been changed to use GCC 4.5.3, so any
253: objdir or DESTDIR for them should be deleted before updating.
254:
1.226 mrg 255: 20110805:
256: The update to GCC 4.5.3 requires a non-trivial portion of
257: the tree to be cleaned. Best to delete both objdir and
258: DESTDIR before running this update. So far, only the
259: sparc64, mips and powerpc platforms have changed.
260:
1.225 matt 261: 20110803:
1.241 wiz 262: The layout of external/public-domain/xz has changed. To do an
1.225 matt 263: update build you will have to remove the contents of the OBJDIR
264: for external/public-domain/xz/bin by hand as the xz entry there
265: is now a directory.
266:
1.223 joerg 267: 20110410:
1.241 wiz 268: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 269: update build you have to clean both tools/binutils and
270: tools/gcc by hand.
1.223 joerg 271:
1.222 plunky 272: 20110328:
273: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 274: ordering issues with "make all". It may be necessary to remove
1.222 plunky 275: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
276: if your update build fails, as the "Xorg" entry there is now a
277: directory.
278:
1.220 joerg 279: 20110121:
1.221 lukem 280: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 281: the build of individual parts of the tree. This is handled
282: correctly by build.sh. Manual builds have to update /usr/share/mk
283: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 284:
1.217 jruoho 285: 20101217:
286: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 287: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 288: group(5) in order to make the program work with existing setups.
289:
1.216 christos 290: 20101125:
291: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 292: variables with names that contain '='. Revision 1.18 of env.c
293: assumed that this was allowed. Installing a new libc with an
1.216 christos 294: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
295: break which affects the autoconf tests for dependency finding,
296: so building gcc will end up printing:
297: checking dependency style of gcc... none
298: configure: error: no usable dependency style found
299: Fix it by rebuilding and re-installing env.
1.138 lukem 300:
1.215 mrg 301: 20101119:
302: Recent Xorg updates in xsrc/external/mit/ may cause various build
303: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
304: have any build problems with xsrc, or problems with mismatched
305: versions between xorg-server and drivers.
306:
1.213 jmmv 307: 20100604:
308: The update of ATF to 0.9 causes old tests written in shell to fail
309: unless they are rebuilt. If you are building with MKUPDATE=yes,
310: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
311: trees by hand.
312:
1.211 tnozaki 313: 20100522:
1.212 mrg 314: Recent Xorg updates in xsrc/external/mit/ will cause various build
315: problems. Delete your entire DESTDIR and OBJDIR if you have any
316: build problems with xsrc.
317:
318: 20100522:
1.211 tnozaki 319: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 320: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 321:
1.210 christos 322: 20100520:
1.241 wiz 323: The location of the xkb compiled descriptions has changed. Please
1.210 christos 324: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
325:
1.209 njoly 326: 20100222:
327: The shared objects file extension has been changed from .so to
328: .pico, in order to avoid conflicts with shared libraries names
329: libXX.so. All now stale regular .so files can be removed from
330: your object directories.
331:
1.208 roy 332: 20100204:
333: The termcap database has been removed from the sources,
334: but has not been marked obsolete so it is not removed
335: from the system when upgrading.
336: As such, you will need to remove them from your object
337: and destination directories.
338:
1.203 dyoung 339: 20091101:
1.205 dholland 340: After updating, it may be necessary to make the 'cleandir'
341: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
342: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
343: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 344:
1.202 mrg 345: 20091001:
1.206 dholland 346: On amd64 you must rebuild tools (to get the new binutils)
347: before building a kernel, or the build fails on cpufunc.S.
348:
349: 20091001:
1.202 mrg 350: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
351: symlink, failing the build. Delete the link, and the subdir
352: it is in, and retry your build.
353:
1.201 dsl 354: 20090718:
355: libc build changed so that strchr() provides the extra entry
1.241 wiz 356: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 357: may fail because the archive contains the unwanted index.o.
358: (Similarly for strrchr() and rindex().)
359:
1.198 mrg 360: 20090709:
361: Native Xorg was upgraded again. Builds will probably fail again
362: without a clean objdir, at least for src/external/mit/xorg.
363:
1.197 mrg 364: 20090616:
365: Native Xorg was upgraded. Builds will need a clean objdir for
366: src/external/mit/xorg. Upgrading a system from sets will not
367: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
368: subdirectory has been changed into a file, and this needs to
369: be manually "rm -r"'ed before installing xbase.tgz.
370:
1.195 perry 371: 20090501:
372: Several new functions were added to string.h/libc, and this
373: can cause autoconf problems during the tool build for people
1.241 wiz 374: who fail to clean out their tools objects properly. If you
1.195 perry 375: note messages about stpcpy, stpncpy or strnlen accompanying a
376: failure during the tool build, clean out all your tools
377: objects and start again.
378:
1.194 mrg 379: 20090325:
380: The i386 port was switched to i486 default toolchain. This requires
381: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
382:
1.192 skrll 383: 20090126:
1.241 wiz 384: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 385: need to 'rm -f __posix_fadvise50.*' in the libc build directory
386: to avoid using the old assembly stub.
1.192 skrll 387:
1.191 joerg 388: 20090202:
389: pkg_install now depends on the pkgdb cache for automatic conflict
390: detection. It is recommented to rebuild the cache with
391: ``pkg_admin rebuild''.
392:
1.184 christos 393: 20090110:
1.241 wiz 394: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
395: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 396: This is needed even in the MODULAR kernel because there is
397: conditionally compiled code in rtsock.c.
1.184 christos 398: 2. make sure build.sh completes and the binaries in a chroot work
399: before installing.
400: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 401: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 402: are installed properly, and start building libraries first libc
403: and libutil, install them and then continue building all the
1.241 wiz 404: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 405: the new libraries are installed, you can restart the build.
406: 4. If you compile packages and you notice link time warnings,

1.241 wiz 414: for utmp. You are better off removing the old files after
1.190 apb 415: upgrading. The automated clearing of /var/run during

551: implementation was repaired. From 20070529 to 20070911 racoon

1.241 wiz 558: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It

1.161 dsl 563: 20070422:

565: has been changed. Rather than modify the pathname (and copy back
566: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 567: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 568: root file system will be relative to that file system - unless they
1.161 dsl 569: start /../ this is useful when the emulated root is a real install

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

1.1 abs 643: Hints for a more successful build:
644: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 645: Use build.sh, but do not use its "expert mode":
1.132 jmmv 646: This will automatically build the tools in the
1.123 jmc 647: correct order, and it will keep the tools and the
648: new build products from interfering with the running
649: system. This will allow you to ignore most of the
650: other advice in this file.
1.2 mrg 651: Build a new kernel first:
652: This makes sure that any new system calls or features
653: expected by the new userland will be present. This
654: helps to avoid critical errors when upgrading.
1.1 abs 655: Use object directories:
656: This helps to keep stale object
657: files from polluting the build if a Makefile "forgets"
658: about one. It also makes it easier to clean up after
659: a build. It's also necessary if you want to use the
660: same source tree for multiple machines.
1.123 jmc 661: To use object directories with build.sh:
662: a) invoke build.sh with the "-M" or "-O" options.
663: To use object directories without using build.sh:
1.1 abs 664: a) cd /usr/src ; make cleandir
1.2 mrg 665: b) Add "OBJMACHINE=yes" to /etc/mk.conf
666: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 667: d) cd /usr/src ; make build
1.2 mrg 668: Note that running "make obj" in a directory will create
669: in obj.$MACHINE directory.
1.1 abs 670: Build to a DESTDIR:
1.123 jmc 671: This helps to keep old installed files (especially libraries)
672: from interfering with the new build.
673: To build to a DESTDIR with build.sh, use the "-D" option.
674: To build to a DESTDIR without using build.sh, set the DESTDIR
675: environment variable before running make build. It should be
676: set to the pathname of an initially empty directory.
677: Problems: if you do not use build.sh, you might need to
678: update critical utilities without using DESTDIR since
679: nothing is executed from what is installed in DESTDIR.
680: (See critical utils, below.)
1.1 abs 681: Build often:
682: This keeps critical utilities current enough to not choke
683: on any other part of the source tree that depends on up to

685: this problem.

694: Again, automatically done by make build.
695:
696: Failsafe rebuild of a small part of the tree:
697: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
698: To make sure you rebuild something correctly you want to do
699: something like the following:
700: 1) Make sure the includes and .mk files are up to date.
701: 2) Make sure any program used to build the particular
702: utility is up to date. (yacc, lex, etc...)
703: 3) cd ...path/to/util...
704: make cleandir
705: rm ...all obj directories...
706: make cleandir # yes, again
707: make obj
708: make depend && make
709:
710: Failsafe rebuild of the entire tree:
711: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
712: If you really want to make sure the source tree is clean and
1.2 mrg 713: ready for a build try the following. Note that sourcing /etc/mk.conf
