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.

1.266 ! aymeric 22: 20160306:
1.265 aymeric 23: NetBSD's regexp implementation is now part of libnbcompat.
24: Nblex, nbm4, nbpax, nbsed use it and they may crash on
25: non-NetBSD hosts if linked with stale object files produced
26: while they included a non-NetBSD regex.h.
27: In any case, you should "make cleandir" at least these tools
28: before updating your toolchain.
29:
1.264 martin 30: 20160125:
31: Dtrace has been enabled by default on some architectures.
32: When doing an update build, make sure to clean the etc/mtree
33: object directory before starting the build - otherwise the
34: needed directories in destdir will not be created.
35: An easy way to do this is:
36: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
37:
1.263 dholland 38: 20150818:
39: New acpica requires "make cleandir" in src/external/bsd/acpica
40: again.
41:
1.262 christos 42: 20150413:
43: New acpica requires "make cleandir" and reinstalling yacc
44: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
45: also "make cleandir" in /usr/src/external/bsd/acpica.
46:
1.261 martin 47: 20150404:
48: Lint changes require a full rebuild of the tool, so make
49: sure to build without -u option to build.sh, or manually
50: do a make cleandir in src/tools/lint1 and
51: src/usr.bin/xlint.
52:
1.260 skrll 53: 20150310:
54: Improvements to openssl for arm mean that update builds of
55: the openssl libraries will fail. A make cleandir in
56: external/bsd/openssl/lib is needed
57:
1.258 martin 58: 20141026:
1.259 msaitoh 59: A mishap during the import of pppd may cause your corruption
1.258 martin 60: in your cvs directory if you happened to do a cvs update
61: during a short period of time. To fix, just remove the
62: directory src/external/bsd/ppp/dist/pppd completely
63: and let cvs restore it on next update.
64:
1.256 apb 65: 20140721:
66: The src/external/mit/lua/src directory was accidentally created
67: and then deleted in the CVS repository. If you get errors like
68:
69: cvs [update aborted]: cannot open directory
70: /cvsroot/src/external/mit/lua/src: No such file or directory
71:
72: then delete your local copy of that directory tree and try again.
73:
1.255 joerg 74: 20140530:
75: ARM eABI switched to DWARF based exception handling. This requires
76: rebuilding all C++ code. It is strongly advised to do a clean build.
77:
1.251 martin 78: 20140131:
1.253 joerg 79: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 80: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 81: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 82:
1.250 christos 83: 20131227:
84: 1. The new ntpd runs in a restricted mode to prevent amplification
85: attacks. If you need ntpdc to work you need to explicitly enable
86: mode7 in your config file. Make sure you put the necessary restrict
87: statements to avoid being exposed.
88: 2. strncat has moved from lib/libc to common/lib/libc; you might need
89: to make clean in libc
90:
1.249 mrg 91: 20131129:
92: The GMP sources were updated, and builds will likely fail without
93: cleaning their build trees for both tools and in-tree, like below.
94:
1.248 mrg 95: 20131128:
96: The MPC and MPFR sources were updated, and builds may require their
97: tools and in-tree directories cleaned for successful updates.
98:
1.246 martin 99: 20130605:
1.247 spz 100: The kernel option FAST_IPSEC no longer exists, it's been renamed
101: to IPSEC (and the older IPSEC version removed).
102:
103: 20130605:
1.246 martin 104: Previous freetype installations eroneously installed private
105: header files. If you are building against a non-empty $DESTDIR,
106: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
107:
1.245 mrg 108: 20130531:
109: The xdm update may cause build failure due to xdm.man being
110: in the obj tree. Make sure to ensure any like this:
111: nbmake: nbmake: don't know how to make xdm.man. Stop
112: is fixed by deleting the xdm.man in the obj tree.
113:
1.244 mrg 114: 20130530:
115: Updates of many xsrc packages will leave old .pc files around.
116: Best to clean out the xsrc objdir entirely before rebuilds.
117:
1.242 christos 118: 20130301:
119: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 120: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 121:
1.238 dholland 122: 20120726:
1.241 wiz 123: The update of OpenSSL requires cleaning both the OpenSSL build
124: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 125: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 126: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 127: cause third-party software to link incorrectly and/or crash.
1.238 dholland 128:
1.237 wiz 129: 20120507:
1.241 wiz 130: The database schema for makemandb was changed. You will
1.237 wiz 131: need to update the database using 'makemandb -f' or wait
132: for the next weekly run to fix it.
133:
1.236 bsh 134: 20120319:
135: sys/conf/Makefile.kern.inc has been modified to adjust the
136: size of db_symtab automatically. You need to update dbsym in
137: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
138: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
139: mk.conf.
140:
1.235 joerg 141: 20120216:
1.241 wiz 142: Default for MKCATPAGES changed to NO. Update builds will fail
143: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 144: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 145: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 146: the next run of weekly will fix it.
1.233 joerg 147:
1.232 christos 148: 20111227:
149: If you built between 20111225 and 20111227 you need to remove
150: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
151: bump has been reverted.
152:
1.231 tls 153: 20111125:
154: The "rnd" pseudodevice has been added to sys/conf/std, which
155: means it should no longer be explicitly listed in kernel
156: configuration files. The line "pseudo-device rnd" should be
157: removed from any custom kernel config files users may have.
158:
1.230 tls 159: 20111119:
160: A problem with the datastructures used by the rndctl(8)
161: utility (pointers in datastructures in an array, making 32->64
162: bit compatibility very painful) has been fixed in a
163: non-backwards-compatible way. If you replace your kernel,
164: replace your rndctl executable too.
1.241 wiz 165:
1.229 jym 166: 20111001:
167: the prop_*_send_syscall() functions from proplib(3) have been
168: changed and their new version is not backward compatible with the old
1.241 wiz 169: one. So ensure that all consumers of these functions (currently:
1.229 jym 170: quota2 code and its tests) are updated together with the new lib.
171:
1.228 mrg 172: 20110817:
173: sparc has been changed to use GCC 4.5.3, so any objdir or
174: DESTDIR for them should be deleted before updating.
175:
1.227 riastrad 176: 20110806:
177: i386 and amd64 have been changed to use GCC 4.5.3, so any
178: objdir or DESTDIR for them should be deleted before updating.
179:
1.226 mrg 180: 20110805:
181: The update to GCC 4.5.3 requires a non-trivial portion of
182: the tree to be cleaned. Best to delete both objdir and
183: DESTDIR before running this update. So far, only the
184: sparc64, mips and powerpc platforms have changed.
185:
1.225 matt 186: 20110803:
1.241 wiz 187: The layout of external/public-domain/xz has changed. To do an
1.225 matt 188: update build you will have to remove the contents of the OBJDIR
189: for external/public-domain/xz/bin by hand as the xz entry there
190: is now a directory.
191:
1.223 joerg 192: 20110410:
1.241 wiz 193: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 194: update build you have to clean both tools/binutils and
195: tools/gcc by hand.
1.223 joerg 196:
1.222 plunky 197: 20110328:
198: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 199: ordering issues with "make all". It may be necessary to remove
1.222 plunky 200: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
201: if your update build fails, as the "Xorg" entry there is now a
202: directory.
203:
1.220 joerg 204: 20110121:
1.221 lukem 205: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 206: the build of individual parts of the tree. This is handled
207: correctly by build.sh. Manual builds have to update /usr/share/mk
208: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 209:
1.217 jruoho 210: 20101217:
211: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 212: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 213: group(5) in order to make the program work with existing setups.
214:
1.216 christos 215: 20101125:
216: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 217: variables with names that contain '='. Revision 1.18 of env.c
218: assumed that this was allowed. Installing a new libc with an
1.216 christos 219: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
220: break which affects the autoconf tests for dependency finding,
221: so building gcc will end up printing:
222: checking dependency style of gcc... none
223: configure: error: no usable dependency style found
224: Fix it by rebuilding and re-installing env.
1.138 lukem 225:
1.215 mrg 226: 20101119:
227: Recent Xorg updates in xsrc/external/mit/ may cause various build
228: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
229: have any build problems with xsrc, or problems with mismatched
230: versions between xorg-server and drivers.
231:
1.213 jmmv 232: 20100604:
233: The update of ATF to 0.9 causes old tests written in shell to fail
234: unless they are rebuilt. If you are building with MKUPDATE=yes,
235: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
236: trees by hand.
237:
1.211 tnozaki 238: 20100522:
1.212 mrg 239: Recent Xorg updates in xsrc/external/mit/ will cause various build
240: problems. Delete your entire DESTDIR and OBJDIR if you have any
241: build problems with xsrc.
242:
243: 20100522:
1.211 tnozaki 244: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 245: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 246:
1.210 christos 247: 20100520:
1.241 wiz 248: The location of the xkb compiled descriptions has changed. Please
1.210 christos 249: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
250:
1.209 njoly 251: 20100222:
252: The shared objects file extension has been changed from .so to
253: .pico, in order to avoid conflicts with shared libraries names
254: libXX.so. All now stale regular .so files can be removed from
255: your object directories.
256:
1.208 roy 257: 20100204:
258: The termcap database has been removed from the sources,
259: but has not been marked obsolete so it is not removed
260: from the system when upgrading.
261: As such, you will need to remove them from your object
262: and destination directories.
263:
1.203 dyoung 264: 20091101:
1.205 dholland 265: After updating, it may be necessary to make the 'cleandir'
266: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
267: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
268: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 269:
1.202 mrg 270: 20091001:
1.206 dholland 271: On amd64 you must rebuild tools (to get the new binutils)
272: before building a kernel, or the build fails on cpufunc.S.
273:
274: 20091001:
1.202 mrg 275: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
276: symlink, failing the build. Delete the link, and the subdir
277: it is in, and retry your build.
278:
1.201 dsl 279: 20090718:
280: libc build changed so that strchr() provides the extra entry
1.241 wiz 281: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 282: may fail because the archive contains the unwanted index.o.
283: (Similarly for strrchr() and rindex().)
284:
1.198 mrg 285: 20090709:
286: Native Xorg was upgraded again. Builds will probably fail again
287: without a clean objdir, at least for src/external/mit/xorg.
288:
1.197 mrg 289: 20090616:
290: Native Xorg was upgraded. Builds will need a clean objdir for
291: src/external/mit/xorg. Upgrading a system from sets will not
292: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
293: subdirectory has been changed into a file, and this needs to
294: be manually "rm -r"'ed before installing xbase.tgz.
295:
1.195 perry 296: 20090501:
297: Several new functions were added to string.h/libc, and this
298: can cause autoconf problems during the tool build for people
1.241 wiz 299: who fail to clean out their tools objects properly. If you
1.195 perry 300: note messages about stpcpy, stpncpy or strnlen accompanying a
301: failure during the tool build, clean out all your tools
302: objects and start again.
303:
1.194 mrg 304: 20090325:
305: The i386 port was switched to i486 default toolchain. This requires
306: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
307:
1.192 skrll 308: 20090126:
1.241 wiz 309: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 310: need to 'rm -f __posix_fadvise50.*' in the libc build directory
311: to avoid using the old assembly stub.
1.192 skrll 312:
1.191 joerg 313: 20090202:
314: pkg_install now depends on the pkgdb cache for automatic conflict
315: detection. It is recommented to rebuild the cache with
316: ``pkg_admin rebuild''.
317:
1.184 christos 318: 20090110:
1.241 wiz 319: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
320: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 321: This is needed even in the MODULAR kernel because there is
322: conditionally compiled code in rtsock.c.
1.184 christos 323: 2. make sure build.sh completes and the binaries in a chroot work
324: before installing.
325: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 326: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 327: are installed properly, and start building libraries first libc
328: and libutil, install them and then continue building all the
1.241 wiz 329: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 330: the new libraries are installed, you can restart the build.
331: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 332: rebuild the required packages to update their shared libraries.
333: Any package you rebuild will require rebuilding all the packages
334: that depend on it.
1.186 christos 335: 5. Next time you run pwd_mkdb with the new binary, the file
336: will be upgraded and it will not be backwards compatible.
1.190 apb 337: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
338: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 339: for utmp. You are better off removing the old files after
1.190 apb 340: upgrading. The automated clearing of /var/run during
341: boot, and the automated rotating of files in /var/log by
342: newsyslog(8), may mean that you do not have to remove the
343: files manually.
344: 7. The optional accounting file (/var/account/acct, see
345: accton(8)) has not been versioned, and will need to be
346: removed. The automatic rotation of the accounting file by
347: /etc/daily limits the bad consequences of failure to remove
348: the file.
1.196 dholland 349: 8. Application software that writes time_t to binary files on
1.241 wiz 350: disk will break or need attention. Most notably: if you are
1.196 dholland 351: using PostgreSQL < 8.4, you need to dump your databases,
352: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 353:
1.183 pgoyette 354: 20081219:
355: config(1) has been updated, and one of the files it creates -
356: swapnetbsd.o - has changed format. You need to rebuild config
357: (done automatically by build.sh) and then you need to rerun
358: config on all kernel configuration files before rebuilding those
359: kernels.
360:
1.181 cube 361: 20081205:
362: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
363: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
364: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 365:
1.179 tsutsui 366: 20081122:
1.182 tsutsui 367: On i386, various kernel options(4) in GENERIC including
1.180 wiz 368: file systems have been disabled and moved into kernel modules.
369: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 370: following files as well as a new GENERIC kernel:
371:
372: - build and install kernel modules from src/sys/modules
373:
374: - install the latest bootloader, which will load a module
1.180 wiz 375: for the file system from which the kernel is loaded automatically
1.179 tsutsui 376:
1.180 wiz 377: If you have to load your kernel from a file system which is not of
378: the same type as the root file system, you have to load the necessary
379: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 380:
1.178 lukem 381: 20080827:
382: If you built and installed a libc from sources between
383: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
384: which results in false errors reported by lint(1).
385: Since this breaks the libc build itself, manual help is
1.180 wiz 386: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 387: $ (cd lib/libc && make MKLINT=no dependall install)
388:
1.177 christos 389: 20080813:
390: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 391: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 392:
1.200 dholland 393: 20080802:
394: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 395: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 396: for -current.
397:

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

478: normal kernel/userspace version matching hygiene is not
479: sufficient to avoid this problem.) Ensure that both kernel

1.241 wiz 483: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It

1.161 dsl 488: 20070422:
489: The way OS emulations lookup filenames inside the emulation root
490: has been changed. Rather than modify the pathname (and copy back
491: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 492: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 493: root file system will be relative to that file system - unless they
1.161 dsl 494: start /../ this is useful when the emulated root is a real install

520: The threading model was changed when the newlock2 branch
521: was merged to NetBSD-current. If you boot with a new
522: kernel (version 4.99.10), then you also need a new pthread
523: library (/usr/lib/libpthread.so.0.7). If you boot with
524: an old kernel, then you need the old pthread library
525: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and

1.1 abs 568: Hints for a more successful build:
569: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 570: Use build.sh, but do not use its "expert mode":
1.132 jmmv 571: This will automatically build the tools in the
1.123 jmc 572: correct order, and it will keep the tools and the
573: new build products from interfering with the running
574: system. This will allow you to ignore most of the
575: other advice in this file.
1.2 mrg 576: Build a new kernel first:
577: This makes sure that any new system calls or features
578: expected by the new userland will be present. This
579: helps to avoid critical errors when upgrading.
1.1 abs 580: Use object directories:
581: This helps to keep stale object
582: files from polluting the build if a Makefile "forgets"
583: about one. It also makes it easier to clean up after
584: a build. It's also necessary if you want to use the
585: same source tree for multiple machines.
1.123 jmc 586: To use object directories with build.sh:
587: a) invoke build.sh with the "-M" or "-O" options.
588: To use object directories without using build.sh:
1.1 abs 589: a) cd /usr/src ; make cleandir
1.2 mrg 590: b) Add "OBJMACHINE=yes" to /etc/mk.conf
591: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 592: d) cd /usr/src ; make build
1.2 mrg 593: Note that running "make obj" in a directory will create
594: in obj.$MACHINE directory.
1.1 abs 595: Build to a DESTDIR:
1.123 jmc 596: This helps to keep old installed files (especially libraries)
597: from interfering with the new build.
598: To build to a DESTDIR with build.sh, use the "-D" option.
599: To build to a DESTDIR without using build.sh, set the DESTDIR
600: environment variable before running make build. It should be
601: set to the pathname of an initially empty directory.
602: Problems: if you do not use build.sh, you might need to
603: update critical utilities without using DESTDIR since
604: nothing is executed from what is installed in DESTDIR.
605: (See critical utils, below.)
1.1 abs 606: Build often:
607: This keeps critical utilities current enough to not choke
608: on any other part of the source tree that depends on up to
1.123 jmc 609: date functionality. If you use build.sh, you should not have
610: this problem.

1.1 abs 612: What to do if things don't work:
613: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 614: When things don't work there are usually a few things that commonly
1.1 abs 615: should be done.
616: 1) make includes
617: This should be done automatically by make build.
618: 2) cd share/mk && make install
619: Again, automatically done by make build.
620:
621: Failsafe rebuild of a small part of the tree:
622: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
623: To make sure you rebuild something correctly you want to do
624: something like the following:
625: 1) Make sure the includes and .mk files are up to date.
626: 2) Make sure any program used to build the particular
627: utility is up to date. (yacc, lex, etc...)
628: 3) cd ...path/to/util...
629: make cleandir
630: rm ...all obj directories...
631: make cleandir # yes, again
632: make obj
633: make depend && make
634:
635: Failsafe rebuild of the entire tree:
636: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
637: If you really want to make sure the source tree is clean and
1.2 mrg 638: ready for a build try the following. Note that sourcing /etc/mk.conf
639: (a make(1) Makefile) in this manner is not right, and will not work
