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:
1.268 riastrad 22: 20160410:
23:
24: amd64 needs full "make cleandir" or deletion of objdir now that
25: PIE has been enabled for amd64. PIE, or position-independent
26: executables, means all code, including executables and not just
27: shared libraries, is position-independent and hence able to be
28: relocated by ASLR, address space layout randomization.
29:
30: The change was made in Makefile variables for compiler and
31: linker flags, for which make(1) does not record dependencies,
32: hence it is unable to detect that all .o files need rebuilding.
33:
34: Partial rebuilds with some modified source files will likely
35: fail when linking executables, since the linker refuses to mix
36: position-independent code with position-dependent code in
37: position-independent executables:
38:
39: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
40:
1.267 mrg 41: 20160401:
42: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 ! dholland 43: Some people have found that cleandir is not sufficient, so if
! 44: in doubt delete the entire object directory tree for gcc.
1.267 mrg 45:
1.266 aymeric 46: 20160306:
1.265 aymeric 47: NetBSD's regexp implementation is now part of libnbcompat.
48: Nblex, nbm4, nbpax, nbsed use it and they may crash on
49: non-NetBSD hosts if linked with stale object files produced
50: while they included a non-NetBSD regex.h.
51: In any case, you should "make cleandir" at least these tools
52: before updating your toolchain.
53:
1.264 martin 54: 20160125:
55: Dtrace has been enabled by default on some architectures.
56: When doing an update build, make sure to clean the etc/mtree
57: object directory before starting the build - otherwise the
58: needed directories in destdir will not be created.
59: An easy way to do this is:
60: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
61:
1.263 dholland 62: 20150818:
63: New acpica requires "make cleandir" in src/external/bsd/acpica
64: again.
65:
1.262 christos 66: 20150413:
67: New acpica requires "make cleandir" and reinstalling yacc
68: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
69: also "make cleandir" in /usr/src/external/bsd/acpica.
70:
1.261 martin 71: 20150404:
72: Lint changes require a full rebuild of the tool, so make
73: sure to build without -u option to build.sh, or manually
74: do a make cleandir in src/tools/lint1 and
75: src/usr.bin/xlint.
76:
1.260 skrll 77: 20150310:
78: Improvements to openssl for arm mean that update builds of
79: the openssl libraries will fail. A make cleandir in
80: external/bsd/openssl/lib is needed
81:
1.258 martin 82: 20141026:
1.259 msaitoh 83: A mishap during the import of pppd may cause your corruption
1.258 martin 84: in your cvs directory if you happened to do a cvs update
85: during a short period of time. To fix, just remove the
86: directory src/external/bsd/ppp/dist/pppd completely
87: and let cvs restore it on next update.
88:
1.256 apb 89: 20140721:
90: The src/external/mit/lua/src directory was accidentally created
91: and then deleted in the CVS repository. If you get errors like
92:
93: cvs [update aborted]: cannot open directory
94: /cvsroot/src/external/mit/lua/src: No such file or directory
95:
96: then delete your local copy of that directory tree and try again.
97:
1.255 joerg 98: 20140530:
99: ARM eABI switched to DWARF based exception handling. This requires
100: rebuilding all C++ code. It is strongly advised to do a clean build.
101:
1.251 martin 102: 20140131:
1.253 joerg 103: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 104: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 105: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 106:
1.250 christos 107: 20131227:
108: 1. The new ntpd runs in a restricted mode to prevent amplification
109: attacks. If you need ntpdc to work you need to explicitly enable
110: mode7 in your config file. Make sure you put the necessary restrict
111: statements to avoid being exposed.
112: 2. strncat has moved from lib/libc to common/lib/libc; you might need
113: to make clean in libc
114:
1.249 mrg 115: 20131129:
116: The GMP sources were updated, and builds will likely fail without
117: cleaning their build trees for both tools and in-tree, like below.
118:
1.248 mrg 119: 20131128:
120: The MPC and MPFR sources were updated, and builds may require their
121: tools and in-tree directories cleaned for successful updates.
122:
1.246 martin 123: 20130605:
1.247 spz 124: The kernel option FAST_IPSEC no longer exists, it's been renamed
125: to IPSEC (and the older IPSEC version removed).
126:
127: 20130605:
1.246 martin 128: Previous freetype installations eroneously installed private
129: header files. If you are building against a non-empty $DESTDIR,
130: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
131:
1.245 mrg 132: 20130531:
133: The xdm update may cause build failure due to xdm.man being
134: in the obj tree. Make sure to ensure any like this:
135: nbmake: nbmake: don't know how to make xdm.man. Stop
136: is fixed by deleting the xdm.man in the obj tree.
137:
1.244 mrg 138: 20130530:
139: Updates of many xsrc packages will leave old .pc files around.
140: Best to clean out the xsrc objdir entirely before rebuilds.
141:
1.242 christos 142: 20130301:
143: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 144: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 145:
1.238 dholland 146: 20120726:
1.241 wiz 147: The update of OpenSSL requires cleaning both the OpenSSL build
148: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 149: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 150: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 151: cause third-party software to link incorrectly and/or crash.
1.238 dholland 152:
1.237 wiz 153: 20120507:
1.241 wiz 154: The database schema for makemandb was changed. You will
1.237 wiz 155: need to update the database using 'makemandb -f' or wait
156: for the next weekly run to fix it.
157:
1.236 bsh 158: 20120319:
159: sys/conf/Makefile.kern.inc has been modified to adjust the
160: size of db_symtab automatically. You need to update dbsym in
161: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
162: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
163: mk.conf.
164:
1.235 joerg 165: 20120216:
1.241 wiz 166: Default for MKCATPAGES changed to NO. Update builds will fail
167: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 168: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 169: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 170: the next run of weekly will fix it.
1.233 joerg 171:
1.232 christos 172: 20111227:
173: If you built between 20111225 and 20111227 you need to remove
174: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
175: bump has been reverted.
176:
1.231 tls 177: 20111125:
178: The "rnd" pseudodevice has been added to sys/conf/std, which
179: means it should no longer be explicitly listed in kernel
180: configuration files. The line "pseudo-device rnd" should be
181: removed from any custom kernel config files users may have.
182:
1.230 tls 183: 20111119:
184: A problem with the datastructures used by the rndctl(8)
185: utility (pointers in datastructures in an array, making 32->64
186: bit compatibility very painful) has been fixed in a
187: non-backwards-compatible way. If you replace your kernel,
188: replace your rndctl executable too.
1.241 wiz 189:
1.229 jym 190: 20111001:
191: the prop_*_send_syscall() functions from proplib(3) have been
192: changed and their new version is not backward compatible with the old
1.241 wiz 193: one. So ensure that all consumers of these functions (currently:
1.229 jym 194: quota2 code and its tests) are updated together with the new lib.
195:
1.228 mrg 196: 20110817:
197: sparc has been changed to use GCC 4.5.3, so any objdir or
198: DESTDIR for them should be deleted before updating.
199:
1.227 riastrad 200: 20110806:
201: i386 and amd64 have been changed to use GCC 4.5.3, so any
202: objdir or DESTDIR for them should be deleted before updating.
203:
1.226 mrg 204: 20110805:
205: The update to GCC 4.5.3 requires a non-trivial portion of
206: the tree to be cleaned. Best to delete both objdir and
207: DESTDIR before running this update. So far, only the
208: sparc64, mips and powerpc platforms have changed.
209:
1.225 matt 210: 20110803:
1.241 wiz 211: The layout of external/public-domain/xz has changed. To do an
1.225 matt 212: update build you will have to remove the contents of the OBJDIR
213: for external/public-domain/xz/bin by hand as the xz entry there
214: is now a directory.
215:
1.223 joerg 216: 20110410:
1.241 wiz 217: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 218: update build you have to clean both tools/binutils and
219: tools/gcc by hand.
1.223 joerg 220:
1.222 plunky 221: 20110328:
222: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 223: ordering issues with "make all". It may be necessary to remove
1.222 plunky 224: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
225: if your update build fails, as the "Xorg" entry there is now a
226: directory.
227:
1.220 joerg 228: 20110121:
1.221 lukem 229: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 230: the build of individual parts of the tree. This is handled
231: correctly by build.sh. Manual builds have to update /usr/share/mk
232: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 233:
1.217 jruoho 234: 20101217:
235: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 236: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 237: group(5) in order to make the program work with existing setups.
238:
1.216 christos 239: 20101125:
240: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 241: variables with names that contain '='. Revision 1.18 of env.c
242: assumed that this was allowed. Installing a new libc with an
1.216 christos 243: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
244: break which affects the autoconf tests for dependency finding,
245: so building gcc will end up printing:
246: checking dependency style of gcc... none
247: configure: error: no usable dependency style found
248: Fix it by rebuilding and re-installing env.
1.138 lukem 249:
1.215 mrg 250: 20101119:
251: Recent Xorg updates in xsrc/external/mit/ may cause various build
252: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
253: have any build problems with xsrc, or problems with mismatched
254: versions between xorg-server and drivers.
255:
1.213 jmmv 256: 20100604:
257: The update of ATF to 0.9 causes old tests written in shell to fail
258: unless they are rebuilt. If you are building with MKUPDATE=yes,
259: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
260: trees by hand.
261:
1.211 tnozaki 262: 20100522:
1.212 mrg 263: Recent Xorg updates in xsrc/external/mit/ will cause various build
264: problems. Delete your entire DESTDIR and OBJDIR if you have any
265: build problems with xsrc.
266:
267: 20100522:
1.211 tnozaki 268: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 269: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 270:
1.210 christos 271: 20100520:
1.241 wiz 272: The location of the xkb compiled descriptions has changed. Please
1.210 christos 273: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
274:
1.209 njoly 275: 20100222:
276: The shared objects file extension has been changed from .so to
277: .pico, in order to avoid conflicts with shared libraries names
278: libXX.so. All now stale regular .so files can be removed from
279: your object directories.
280:
1.208 roy 281: 20100204:
282: The termcap database has been removed from the sources,
283: but has not been marked obsolete so it is not removed
284: from the system when upgrading.
285: As such, you will need to remove them from your object
286: and destination directories.
287:
1.203 dyoung 288: 20091101:
1.205 dholland 289: After updating, it may be necessary to make the 'cleandir'
290: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
291: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
292: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 293:
1.202 mrg 294: 20091001:
1.206 dholland 295: On amd64 you must rebuild tools (to get the new binutils)
296: before building a kernel, or the build fails on cpufunc.S.
297:
298: 20091001:
1.202 mrg 299: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
300: symlink, failing the build. Delete the link, and the subdir
301: it is in, and retry your build.
302:
1.201 dsl 303: 20090718:
304: libc build changed so that strchr() provides the extra entry
1.241 wiz 305: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 306: may fail because the archive contains the unwanted index.o.
307: (Similarly for strrchr() and rindex().)
308:
1.198 mrg 309: 20090709:
310: Native Xorg was upgraded again. Builds will probably fail again
311: without a clean objdir, at least for src/external/mit/xorg.
312:
1.197 mrg 313: 20090616:
314: Native Xorg was upgraded. Builds will need a clean objdir for
315: src/external/mit/xorg. Upgrading a system from sets will not
316: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
317: subdirectory has been changed into a file, and this needs to
318: be manually "rm -r"'ed before installing xbase.tgz.
319:
1.195 perry 320: 20090501:
321: Several new functions were added to string.h/libc, and this
322: can cause autoconf problems during the tool build for people
1.241 wiz 323: who fail to clean out their tools objects properly. If you
1.195 perry 324: note messages about stpcpy, stpncpy or strnlen accompanying a
325: failure during the tool build, clean out all your tools
326: objects and start again.
327:
1.194 mrg 328: 20090325:
329: The i386 port was switched to i486 default toolchain. This requires
330: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
331:
1.192 skrll 332: 20090126:
1.241 wiz 333: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 334: need to 'rm -f __posix_fadvise50.*' in the libc build directory
335: to avoid using the old assembly stub.
1.192 skrll 336:
1.191 joerg 337: 20090202:
338: pkg_install now depends on the pkgdb cache for automatic conflict
339: detection. It is recommented to rebuild the cache with
340: ``pkg_admin rebuild''.
341:
1.184 christos 342: 20090110:
1.241 wiz 343: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
344: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 345: This is needed even in the MODULAR kernel because there is
346: conditionally compiled code in rtsock.c.
1.184 christos 347: 2. make sure build.sh completes and the binaries in a chroot work
348: before installing.
349: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 350: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 351: are installed properly, and start building libraries first libc
352: and libutil, install them and then continue building all the
1.241 wiz 353: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 354: the new libraries are installed, you can restart the build.
355: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 356: rebuild the required packages to update their shared libraries.
357: Any package you rebuild will require rebuilding all the packages
358: that depend on it.
1.186 christos 359: 5. Next time you run pwd_mkdb with the new binary, the file
360: will be upgraded and it will not be backwards compatible.
1.190 apb 361: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
362: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 363: for utmp. You are better off removing the old files after
1.190 apb 364: upgrading. The automated clearing of /var/run during
365: boot, and the automated rotating of files in /var/log by
366: newsyslog(8), may mean that you do not have to remove the
367: files manually.
368: 7. The optional accounting file (/var/account/acct, see
369: accton(8)) has not been versioned, and will need to be
370: removed. The automatic rotation of the accounting file by
371: /etc/daily limits the bad consequences of failure to remove
372: the file.
1.196 dholland 373: 8. Application software that writes time_t to binary files on
1.241 wiz 374: disk will break or need attention. Most notably: if you are
1.196 dholland 375: using PostgreSQL < 8.4, you need to dump your databases,
376: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 377:
1.183 pgoyette 378: 20081219:
379: config(1) has been updated, and one of the files it creates -
380: swapnetbsd.o - has changed format. You need to rebuild config
381: (done automatically by build.sh) and then you need to rerun
382: config on all kernel configuration files before rebuilding those
383: kernels.
384:
1.181 cube 385: 20081205:
386: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
387: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
388: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 389:
1.179 tsutsui 390: 20081122:
1.182 tsutsui 391: On i386, various kernel options(4) in GENERIC including
1.180 wiz 392: file systems have been disabled and moved into kernel modules.
393: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 394: following files as well as a new GENERIC kernel:
395:
396: - build and install kernel modules from src/sys/modules
397:
398: - install the latest bootloader, which will load a module
1.180 wiz 399: for the file system from which the kernel is loaded automatically
1.179 tsutsui 400:

1.241 wiz 516: root. One side effect is that absolute symlinks inside the emulated

1.1 abs 592: Hints for a more successful build:
593: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 594: Use build.sh, but do not use its "expert mode":
1.132 jmmv 595: This will automatically build the tools in the
1.123 jmc 596: correct order, and it will keep the tools and the
597: new build products from interfering with the running
598: system. This will allow you to ignore most of the
599: other advice in this file.
1.2 mrg 600: Build a new kernel first:
601: This makes sure that any new system calls or features
602: expected by the new userland will be present. This
603: helps to avoid critical errors when upgrading.
1.1 abs 604: Use object directories:
605: This helps to keep stale object
606: files from polluting the build if a Makefile "forgets"
607: about one. It also makes it easier to clean up after
608: a build. It's also necessary if you want to use the
609: same source tree for multiple machines.
1.123 jmc 610: To use object directories with build.sh:
611: a) invoke build.sh with the "-M" or "-O" options.
612: To use object directories without using build.sh:
1.1 abs 613: a) cd /usr/src ; make cleandir
1.2 mrg 614: b) Add "OBJMACHINE=yes" to /etc/mk.conf
615: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 616: d) cd /usr/src ; make build
1.2 mrg 617: Note that running "make obj" in a directory will create
618: in obj.$MACHINE directory.
1.1 abs 619: Build to a DESTDIR:
1.123 jmc 620: This helps to keep old installed files (especially libraries)
621: from interfering with the new build.
622: To build to a DESTDIR with build.sh, use the "-D" option.
623: To build to a DESTDIR without using build.sh, set the DESTDIR
624: environment variable before running make build. It should be
625: set to the pathname of an initially empty directory.
626: Problems: if you do not use build.sh, you might need to
627: update critical utilities without using DESTDIR since
628: nothing is executed from what is installed in DESTDIR.
629: (See critical utils, below.)
1.1 abs 630: Build often:
631: This keeps critical utilities current enough to not choke
632: on any other part of the source tree that depends on up to
1.123 jmc 633: date functionality. If you use build.sh, you should not have
634: this problem.

643: Again, automatically done by make build.
644:
645: Failsafe rebuild of a small part of the tree:
646: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
647: To make sure you rebuild something correctly you want to do
648: something like the following:
649: 1) Make sure the includes and .mk files are up to date.
650: 2) Make sure any program used to build the particular
651: utility is up to date. (yacc, lex, etc...)
652: 3) cd ...path/to/util...
653: make cleandir
654: rm ...all obj directories...
655: make cleandir # yes, again
656: make obj
657: make depend && make
658:
659: Failsafe rebuild of the entire tree:
660: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
661: If you really want to make sure the source tree is clean and
1.2 mrg 662: ready for a build try the following. Note that sourcing /etc/mk.conf
