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.

1.257 apb 14: Sections are marked with "^^^^^". After the section on "Recent changes"
15: are several sections containing more general information.

19: Recent changes:
20: ^^^^^^^^^^^^^^^
1.230 tls 21:
1.287 ! kre 22: 20171010:
! 23: a change to the build structure of external/bsd/acpica/bin/iasl
! 24: means that its objdir (or *.d and .depend at least) might need
! 25: to be manually removed - or a build done once without -u.
! 26:
1.286 mrg 27: 20170822:
28: a new version of GMP has been imported and probably
29: will break parts of builds related to themselves or GCC, both
30: in the tools and the native section. Remove all GCC, GMP, MPFR
31: and MPC objdirs or build once without -u.
32:
1.285 mrg 33: 20170816:
34: a new version of MPFR and MPC have been imported and probably
35: will break parts of builds related to themselves or GCC, both
36: in the tools and the native section. Remove all GCC, GMP, MPFR
37: and MPC objdirs or build once without -u.
38:
1.284 martin 39: 20170402:
40: a new version of dhcpcd has been imported, which does not support
41: update builds from the previous version. Remove your
42: external/bsd/dhcpcd object dir or build once without -u.
43:
1.281 roy 44: 20170211:
45: a new terminfo database has been imported.
46: The structure of it has changed slightly from prior versions and
47: an updated tic tool is required.
48: If you build.sh, don't use -u
49:
1.280 kre 50: 20170207:
1.278 kre 51: various arch dependent libc/exect.S files were removed
1.279 kre 52: Either remove the obj directories (lib/libc and compat/amd64/i386/lib
53: if it exists) or do a clean build.
54: (This is a bug in the make system, it should be corrected without
55: human intervention, but isn't.)
1.278 kre 56:
1.277 martin 57: 20170104:
58: xinput build options have changed.
59: Remove the obj directory (external/mit/xorg/bin/xinput)
60: if you build.sh -u
61:
1.276 martin 62: 20170103:
63: a new version of flex has been imported.
64: Remove the file from obj (external/bsd/flex)
65: if you build.sh -u
66:
1.275 spz 67: 20161014:
68: a new version of OpenSSL has been imported.
69: Remove the files from obj (crypto/external/bsd/openssl)
70: if you build.sh -u
71:
1.274 martin 72: 20161009:
73: a new version of dhcpcd has been imported with slightly changed
74: build infrastructure. When doing a build.sh -u this requires
75: pruning the external/bsd/dhcpcd objdir.
76:
1.273 mrg 77: 20160914:
78: i386, amd64, shark, ofppc and macppc have joined shark and x68k
79: ports in using xorg-server 1.18. This requires a clean destdir
80: and a clean objdir.
81:
1.272 dholland 82: 20160527:
83: i386 needs a full cleandir or objdir deletion because PIE has
84: been enabled. (see the amd64 entry two down for further info)
85:
1.270 christos 86: 20160418:
87: libedit needs manual removal of all autogenerated files since
1.271 christos 88: some of them are not autogenerated anymore. Remember that there
89: might be two copies of libedit if your platform builds "compat".
1.270 christos 90:
1.268 riastrad 91: 20160410:
92: amd64 needs full "make cleandir" or deletion of objdir now that
93: PIE has been enabled for amd64. PIE, or position-independent
94: executables, means all code, including executables and not just
95: shared libraries, is position-independent and hence able to be
96: relocated by ASLR, address space layout randomization.
97:
98: The change was made in Makefile variables for compiler and
99: linker flags, for which make(1) does not record dependencies,
100: hence it is unable to detect that all .o files need rebuilding.
101:
102: Partial rebuilds with some modified source files will likely
103: fail when linking executables, since the linker refuses to mix
104: position-independent code with position-dependent code in
105: position-independent executables:
106:
107: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
108:
1.267 mrg 109: 20160401:
110: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 111: Some people have found that cleandir is not sufficient, so if
112: in doubt delete the entire object directory tree for gcc.
1.267 mrg 113:
1.266 aymeric 114: 20160306:
1.265 aymeric 115: NetBSD's regexp implementation is now part of libnbcompat.
116: Nblex, nbm4, nbpax, nbsed use it and they may crash on
117: non-NetBSD hosts if linked with stale object files produced
118: while they included a non-NetBSD regex.h.
119: In any case, you should "make cleandir" at least these tools
120: before updating your toolchain.
121:
1.264 martin 122: 20160125:
123: Dtrace has been enabled by default on some architectures.
124: When doing an update build, make sure to clean the etc/mtree
125: object directory before starting the build - otherwise the
126: needed directories in destdir will not be created.
127: An easy way to do this is:
128: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
129:
1.263 dholland 130: 20150818:
131: New acpica requires "make cleandir" in src/external/bsd/acpica
132: again.
133:
1.262 christos 134: 20150413:
135: New acpica requires "make cleandir" and reinstalling yacc
136: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
137: also "make cleandir" in /usr/src/external/bsd/acpica.
138:
1.261 martin 139: 20150404:
140: Lint changes require a full rebuild of the tool, so make
141: sure to build without -u option to build.sh, or manually
142: do a make cleandir in src/tools/lint1 and
143: src/usr.bin/xlint.
144:
1.260 skrll 145: 20150310:
146: Improvements to openssl for arm mean that update builds of
147: the openssl libraries will fail. A make cleandir in
148: external/bsd/openssl/lib is needed
149:
1.258 martin 150: 20141026:
1.259 msaitoh 151: A mishap during the import of pppd may cause your corruption
1.258 martin 152: in your cvs directory if you happened to do a cvs update
153: during a short period of time. To fix, just remove the
154: directory src/external/bsd/ppp/dist/pppd completely
155: and let cvs restore it on next update.
156:
1.256 apb 157: 20140721:
158: The src/external/mit/lua/src directory was accidentally created
159: and then deleted in the CVS repository. If you get errors like
160:
161: cvs [update aborted]: cannot open directory
162: /cvsroot/src/external/mit/lua/src: No such file or directory
163:
164: then delete your local copy of that directory tree and try again.
165:
1.255 joerg 166: 20140530:
167: ARM eABI switched to DWARF based exception handling. This requires
168: rebuilding all C++ code. It is strongly advised to do a clean build.
169:
1.251 martin 170: 20140131:
1.253 joerg 171: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 172: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 173: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 174:
1.250 christos 175: 20131227:
176: 1. The new ntpd runs in a restricted mode to prevent amplification
177: attacks. If you need ntpdc to work you need to explicitly enable
178: mode7 in your config file. Make sure you put the necessary restrict
179: statements to avoid being exposed.
180: 2. strncat has moved from lib/libc to common/lib/libc; you might need
181: to make clean in libc
182:
1.249 mrg 183: 20131129:
184: The GMP sources were updated, and builds will likely fail without
185: cleaning their build trees for both tools and in-tree, like below.
186:
1.248 mrg 187: 20131128:
188: The MPC and MPFR sources were updated, and builds may require their
189: tools and in-tree directories cleaned for successful updates.
190:
1.246 martin 191: 20130605:
1.247 spz 192: The kernel option FAST_IPSEC no longer exists, it's been renamed
193: to IPSEC (and the older IPSEC version removed).
194:
195: 20130605:
1.246 martin 196: Previous freetype installations eroneously installed private
197: header files. If you are building against a non-empty $DESTDIR,
198: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
199:
1.245 mrg 200: 20130531:
201: The xdm update may cause build failure due to xdm.man being
202: in the obj tree. Make sure to ensure any like this:
203: nbmake: nbmake: don't know how to make xdm.man. Stop
204: is fixed by deleting the xdm.man in the obj tree.
205:
1.244 mrg 206: 20130530:
207: Updates of many xsrc packages will leave old .pc files around.
208: Best to clean out the xsrc objdir entirely before rebuilds.
209:
1.242 christos 210: 20130301:
211: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 212: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 213:
1.238 dholland 214: 20120726:
1.241 wiz 215: The update of OpenSSL requires cleaning both the OpenSSL build
216: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 217: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 218: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 219: cause third-party software to link incorrectly and/or crash.
1.238 dholland 220:
1.237 wiz 221: 20120507:
1.241 wiz 222: The database schema for makemandb was changed. You will
1.237 wiz 223: need to update the database using 'makemandb -f' or wait
224: for the next weekly run to fix it.
225:
1.236 bsh 226: 20120319:
227: sys/conf/Makefile.kern.inc has been modified to adjust the
228: size of db_symtab automatically. You need to update dbsym in
229: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
230: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
231: mk.conf.
232:
1.235 joerg 233: 20120216:
1.241 wiz 234: Default for MKCATPAGES changed to NO. Update builds will fail
235: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 236: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 237: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 238: the next run of weekly will fix it.
1.233 joerg 239:
1.232 christos 240: 20111227:
241: If you built between 20111225 and 20111227 you need to remove
242: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
243: bump has been reverted.
244:
1.231 tls 245: 20111125:
246: The "rnd" pseudodevice has been added to sys/conf/std, which
247: means it should no longer be explicitly listed in kernel
248: configuration files. The line "pseudo-device rnd" should be
249: removed from any custom kernel config files users may have.
250:
1.230 tls 251: 20111119:
252: A problem with the datastructures used by the rndctl(8)
253: utility (pointers in datastructures in an array, making 32->64
254: bit compatibility very painful) has been fixed in a
255: non-backwards-compatible way. If you replace your kernel,
256: replace your rndctl executable too.
1.241 wiz 257:
1.229 jym 258: 20111001:
259: the prop_*_send_syscall() functions from proplib(3) have been
260: changed and their new version is not backward compatible with the old
1.241 wiz 261: one. So ensure that all consumers of these functions (currently:
1.229 jym 262: quota2 code and its tests) are updated together with the new lib.
263:
1.228 mrg 264: 20110817:
265: sparc has been changed to use GCC 4.5.3, so any objdir or
266: DESTDIR for them should be deleted before updating.
267:
1.227 riastrad 268: 20110806:
269: i386 and amd64 have been changed to use GCC 4.5.3, so any
270: objdir or DESTDIR for them should be deleted before updating.
271:
1.226 mrg 272: 20110805:
273: The update to GCC 4.5.3 requires a non-trivial portion of
274: the tree to be cleaned. Best to delete both objdir and
275: DESTDIR before running this update. So far, only the
276: sparc64, mips and powerpc platforms have changed.
277:
1.225 matt 278: 20110803:
1.241 wiz 279: The layout of external/public-domain/xz has changed. To do an
1.225 matt 280: update build you will have to remove the contents of the OBJDIR
281: for external/public-domain/xz/bin by hand as the xz entry there
282: is now a directory.
283:
1.223 joerg 284: 20110410:
1.241 wiz 285: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 286: update build you have to clean both tools/binutils and
287: tools/gcc by hand.
1.223 joerg 288:
1.222 plunky 289: 20110328:
290: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 291: ordering issues with "make all". It may be necessary to remove
1.222 plunky 292: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
293: if your update build fails, as the "Xorg" entry there is now a
294: directory.
295:
1.220 joerg 296: 20110121:
1.221 lukem 297: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 298: the build of individual parts of the tree. This is handled
299: correctly by build.sh. Manual builds have to update /usr/share/mk
300: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 301:
1.217 jruoho 302: 20101217:
303: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 304: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 305: group(5) in order to make the program work with existing setups.
306:
1.216 christos 307: 20101125:
308: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 309: variables with names that contain '='. Revision 1.18 of env.c
310: assumed that this was allowed. Installing a new libc with an
1.216 christos 311: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
312: break which affects the autoconf tests for dependency finding,
313: so building gcc will end up printing:
314: checking dependency style of gcc... none
315: configure: error: no usable dependency style found
316: Fix it by rebuilding and re-installing env.
1.138 lukem 317:
1.215 mrg 318: 20101119:
319: Recent Xorg updates in xsrc/external/mit/ may cause various build
320: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
321: have any build problems with xsrc, or problems with mismatched
322: versions between xorg-server and drivers.
323:
1.213 jmmv 324: 20100604:
325: The update of ATF to 0.9 causes old tests written in shell to fail
326: unless they are rebuilt. If you are building with MKUPDATE=yes,
327: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
328: trees by hand.
329:
1.211 tnozaki 330: 20100522:
1.212 mrg 331: Recent Xorg updates in xsrc/external/mit/ will cause various build
332: problems. Delete your entire DESTDIR and OBJDIR if you have any
333: build problems with xsrc.
334:
335: 20100522:
1.211 tnozaki 336: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 337: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 338:
1.210 christos 339: 20100520:
1.241 wiz 340: The location of the xkb compiled descriptions has changed. Please
1.210 christos 341: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
342:
1.209 njoly 343: 20100222:
344: The shared objects file extension has been changed from .so to
345: .pico, in order to avoid conflicts with shared libraries names
346: libXX.so. All now stale regular .so files can be removed from
347: your object directories.
348:
1.208 roy 349: 20100204:
350: The termcap database has been removed from the sources,
351: but has not been marked obsolete so it is not removed
352: from the system when upgrading.
353: As such, you will need to remove them from your object
354: and destination directories.
355:
1.203 dyoung 356: 20091101:
1.205 dholland 357: After updating, it may be necessary to make the 'cleandir'
358: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
359: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
360: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 361:
1.202 mrg 362: 20091001:
1.206 dholland 363: On amd64 you must rebuild tools (to get the new binutils)
364: before building a kernel, or the build fails on cpufunc.S.
365:
366: 20091001:
1.202 mrg 367: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
368: symlink, failing the build. Delete the link, and the subdir
369: it is in, and retry your build.
370:
1.201 dsl 371: 20090718:
372: libc build changed so that strchr() provides the extra entry
1.241 wiz 373: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 374: may fail because the archive contains the unwanted index.o.
375: (Similarly for strrchr() and rindex().)
376:
1.198 mrg 377: 20090709:
378: Native Xorg was upgraded again. Builds will probably fail again
379: without a clean objdir, at least for src/external/mit/xorg.
380:
1.197 mrg 381: 20090616:
382: Native Xorg was upgraded. Builds will need a clean objdir for
383: src/external/mit/xorg. Upgrading a system from sets will not
384: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
385: subdirectory has been changed into a file, and this needs to
386: be manually "rm -r"'ed before installing xbase.tgz.
387:
1.195 perry 388: 20090501:
389: Several new functions were added to string.h/libc, and this
390: can cause autoconf problems during the tool build for people
1.241 wiz 391: who fail to clean out their tools objects properly. If you
1.195 perry 392: note messages about stpcpy, stpncpy or strnlen accompanying a
393: failure during the tool build, clean out all your tools
394: objects and start again.
395:
1.194 mrg 396: 20090325:
397: The i386 port was switched to i486 default toolchain. This requires
398: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
399:
1.192 skrll 400: 20090126:
1.241 wiz 401: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 402: need to 'rm -f __posix_fadvise50.*' in the libc build directory
403: to avoid using the old assembly stub.
1.192 skrll 404:
1.191 joerg 405: 20090202:
406: pkg_install now depends on the pkgdb cache for automatic conflict
407: detection. It is recommented to rebuild the cache with
408: ``pkg_admin rebuild''.
409:
1.184 christos 410: 20090110:
1.241 wiz 411: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
412: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 413: This is needed even in the MODULAR kernel because there is
414: conditionally compiled code in rtsock.c.
1.184 christos 415: 2. make sure build.sh completes and the binaries in a chroot work
416: before installing.
417: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 418: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 419: are installed properly, and start building libraries first libc
420: and libutil, install them and then continue building all the
1.241 wiz 421: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 422: the new libraries are installed, you can restart the build.
423: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 424: rebuild the required packages to update their shared libraries.
425: Any package you rebuild will require rebuilding all the packages
426: that depend on it.
1.186 christos 427: 5. Next time you run pwd_mkdb with the new binary, the file
428: will be upgraded and it will not be backwards compatible.
1.190 apb 429: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
430: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 431: for utmp. You are better off removing the old files after
1.190 apb 432: upgrading. The automated clearing of /var/run during
433: boot, and the automated rotating of files in /var/log by
434: newsyslog(8), may mean that you do not have to remove the
435: files manually.
436: 7. The optional accounting file (/var/account/acct, see
437: accton(8)) has not been versioned, and will need to be
438: removed. The automatic rotation of the accounting file by
439: /etc/daily limits the bad consequences of failure to remove
440: the file.
1.196 dholland 441: 8. Application software that writes time_t to binary files on
1.241 wiz 442: disk will break or need attention. Most notably: if you are
1.196 dholland 443: using PostgreSQL < 8.4, you need to dump your databases,
444: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 445:
1.183 pgoyette 446: 20081219:
447: config(1) has been updated, and one of the files it creates -
448: swapnetbsd.o - has changed format. You need to rebuild config
449: (done automatically by build.sh) and then you need to rerun
450: config on all kernel configuration files before rebuilding those
451: kernels.
452:
1.181 cube 453: 20081205:
454: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
455: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
456: set and will appear as extra files for MKX11=no update builds.

1.179 tsutsui 458: 20081122:
1.182 tsutsui 459: On i386, various kernel options(4) in GENERIC including
1.180 wiz 460: file systems have been disabled and moved into kernel modules.
461: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 462: following files as well as a new GENERIC kernel:
463:
464: - build and install kernel modules from src/sys/modules
465:
466: - install the latest bootloader, which will load a module
1.180 wiz 467: for the file system from which the kernel is loaded automatically
1.179 tsutsui 468:
1.180 wiz 469: If you have to load your kernel from a file system which is not of
470: the same type as the root file system, you have to load the necessary
471: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 472:
1.178 lukem 473: 20080827:
474: If you built and installed a libc from sources between
475: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
476: which results in false errors reported by lint(1).
477: Since this breaks the libc build itself, manual help is
1.180 wiz 478: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 479: $ (cd lib/libc && make MKLINT=no dependall install)
480:
1.177 christos 481: 20080813:
482: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 483: about .go files. You need to remove all .depend files and rebuild.

1.200 dholland 485: 20080802:
486: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 487: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 488: for -current.
489:
490: Threaded programs (using libpthread) and C++ programs (using
491: libstdc++) compiled after 20070907 and before 20080802 need to
492: be recompiled.
493:
494: One way to find affected pkgsrc packages:
495:
496: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
497: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO

1.175 simonb 499: 20080731:
500: WAPBL (metadata journaling support) has been added, but at this
501: time isn't backwards compatible with pre-WAPBL aware kernels
502: and userland (fsck_ffs in particular). Please make sure you
503: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 504: especially an uncleanly mounted journaled filesystem. WAPBL
505: also requires the super block to be in the UFS2 format. You
506: can use fsck_ffs -c 4 to update the superblock format.

1.241 wiz 513: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
514: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 515: utility needs to be rebuilt and reinstalled as older binaries

551: argument specified in the kernel configuration file is not valid
1.241 wiz 552: anymore. The itesio(4) driver now uses the Super I/O address port

1.166 xtraeme 555:
1.165 jmmv 556: 20071028:
557: The pccons(4) driver has been removed from the NetBSD/shark port.
558: You need to update any custom kernel configuration file you have
559: to remove any references to pccons (which includes removing the
560: now useless XSERVER option) and replace them with the correct

1.164 gdt 564: 20070913:
565: A latent bug in dhclient/dhcpd that caused it to be unable to
566: enumerate interfaces was fixed. The bug began to cause
567: problems after 20070911 when the kernel's SIOCGIFCONF
568: implementation was repaired. From 20070529 to 20070911 racoon
569: could not enumerate interfaces. (These are noted because
570: normal kernel/userspace version matching hygiene is not
571: sufficient to avoid this problem.) Ensure that both kernel
572: and userland are from after 20070913.
573:

1.241 wiz 575: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
1.199 dholland 576: calls the target-specific strip program, and the logic to pass
577: down STRIP from make has been removed. This requires a
578: re-installation of tools.
1.163 joerg 579:
1.161 dsl 580: 20070422:
581: The way OS emulations lookup filenames inside the emulation root
582: has been changed. Rather than modify the pathname (and copy back
583: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 584: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 585: root file system will be relative to that file system - unless they
1.161 dsl 586: start /../ this is useful when the emulated root is a real install

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

1.1 abs 660: Hints for a more successful build:
661: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 662: Use build.sh, but do not use its "expert mode":
1.132 jmmv 663: This will automatically build the tools in the
1.123 jmc 664: correct order, and it will keep the tools and the
665: new build products from interfering with the running
666: system. This will allow you to ignore most of the
667: other advice in this file.
1.2 mrg 668: Build a new kernel first:
669: This makes sure that any new system calls or features
670: expected by the new userland will be present. This
671: helps to avoid critical errors when upgrading.
1.1 abs 672: Use object directories:
673: This helps to keep stale object
674: files from polluting the build if a Makefile "forgets"
675: about one. It also makes it easier to clean up after
676: a build. It's also necessary if you want to use the
677: same source tree for multiple machines.
1.123 jmc 678: To use object directories with build.sh:
679: a) invoke build.sh with the "-M" or "-O" options.
680: To use object directories without using build.sh:
1.1 abs 681: a) cd /usr/src ; make cleandir
1.2 mrg 682: b) Add "OBJMACHINE=yes" to /etc/mk.conf
683: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 684: d) cd /usr/src ; make build
1.2 mrg 685: Note that running "make obj" in a directory will create
686: in obj.$MACHINE directory.
1.1 abs 687: Build to a DESTDIR:
1.123 jmc 688: This helps to keep old installed files (especially libraries)
689: from interfering with the new build.
690: To build to a DESTDIR with build.sh, use the "-D" option.
691: To build to a DESTDIR without using build.sh, set the DESTDIR
692: environment variable before running make build. It should be
693: set to the pathname of an initially empty directory.
694: Problems: if you do not use build.sh, you might need to
695: update critical utilities without using DESTDIR since
696: nothing is executed from what is installed in DESTDIR.
697: (See critical utils, below.)
1.1 abs 698: Build often:
699: This keeps critical utilities current enough to not choke
700: on any other part of the source tree that depends on up to
1.123 jmc 701: date functionality. If you use build.sh, you should not have
702: this problem.

1.1 abs 704: What to do if things don't work:
705: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 706: When things don't work there are usually a few things that commonly
1.1 abs 707: should be done.
708: 1) make includes
709: This should be done automatically by make build.
710: 2) cd share/mk && make install
711: Again, automatically done by make build.
712:
713: Failsafe rebuild of a small part of the tree:
714: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
715: To make sure you rebuild something correctly you want to do
716: something like the following:
717: 1) Make sure the includes and .mk files are up to date.
718: 2) Make sure any program used to build the particular
719: utility is up to date. (yacc, lex, etc...)
720: 3) cd ...path/to/util...
721: make cleandir
722: rm ...all obj directories...
723: make cleandir # yes, again
724: make obj
725: make depend && make
726:
727: Failsafe rebuild of the entire tree:
728: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
729: If you really want to make sure the source tree is clean and
1.2 mrg 730: ready for a build try the following. Note that sourcing /etc/mk.conf

821: Cause: If a directory is created by mistake, then it is sometimes
822: deleted from the CVS repository using administrative commands
823: that bypass the normal cvs access controls. If your cvs working tree
824: contains references to a directory that has been deleted on the
825: server in this way, then "cvs update" reports this error.
826: Fix: Recursively delete the affected directory from your working tree
827: and try the update again.
