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:
1.272 ! dholland 22: 20160527:
! 23: i386 needs a full cleandir or objdir deletion because PIE has
! 24: been enabled. (see the amd64 entry two down for further info)
! 25:
1.270 christos 26: 20160418:
27: libedit needs manual removal of all autogenerated files since
1.271 christos 28: some of them are not autogenerated anymore. Remember that there
29: might be two copies of libedit if your platform builds "compat".
1.270 christos 30:
1.268 riastrad 31: 20160410:
32: amd64 needs full "make cleandir" or deletion of objdir now that
33: PIE has been enabled for amd64. PIE, or position-independent
34: executables, means all code, including executables and not just
35: shared libraries, is position-independent and hence able to be
36: relocated by ASLR, address space layout randomization.
37:
38: The change was made in Makefile variables for compiler and
39: linker flags, for which make(1) does not record dependencies,
40: hence it is unable to detect that all .o files need rebuilding.
41:
42: Partial rebuilds with some modified source files will likely
43: fail when linking executables, since the linker refuses to mix
44: position-independent code with position-dependent code in
45: position-independent executables:
46:
47: .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
48:
1.267 mrg 49: 20160401:
50: Ports switching to GCC 5.3 will need a full "make cleandir".
1.269 dholland 51: Some people have found that cleandir is not sufficient, so if
52: in doubt delete the entire object directory tree for gcc.
1.267 mrg 53:
1.266 aymeric 54: 20160306:
1.265 aymeric 55: NetBSD's regexp implementation is now part of libnbcompat.
56: Nblex, nbm4, nbpax, nbsed use it and they may crash on
57: non-NetBSD hosts if linked with stale object files produced
58: while they included a non-NetBSD regex.h.
59: In any case, you should "make cleandir" at least these tools
60: before updating your toolchain.
61:
1.264 martin 62: 20160125:
63: Dtrace has been enabled by default on some architectures.
64: When doing an update build, make sure to clean the etc/mtree
65: object directory before starting the build - otherwise the
66: needed directories in destdir will not be created.
67: An easy way to do this is:
68: cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
69:
1.263 dholland 70: 20150818:
71: New acpica requires "make cleandir" in src/external/bsd/acpica
72: again.
73:
1.262 christos 74: 20150413:
75: New acpica requires "make cleandir" and reinstalling yacc
76: in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
77: also "make cleandir" in /usr/src/external/bsd/acpica.
78:
1.261 martin 79: 20150404:
80: Lint changes require a full rebuild of the tool, so make
81: sure to build without -u option to build.sh, or manually
82: do a make cleandir in src/tools/lint1 and
83: src/usr.bin/xlint.
84:
1.260 skrll 85: 20150310:
86: Improvements to openssl for arm mean that update builds of
87: the openssl libraries will fail. A make cleandir in
88: external/bsd/openssl/lib is needed
89:
1.258 martin 90: 20141026:
1.259 msaitoh 91: A mishap during the import of pppd may cause your corruption
1.258 martin 92: in your cvs directory if you happened to do a cvs update
93: during a short period of time. To fix, just remove the
94: directory src/external/bsd/ppp/dist/pppd completely
95: and let cvs restore it on next update.
96:
1.256 apb 97: 20140721:
98: The src/external/mit/lua/src directory was accidentally created
99: and then deleted in the CVS repository. If you get errors like
100:
101: cvs [update aborted]: cannot open directory
102: /cvsroot/src/external/mit/lua/src: No such file or directory
103:
104: then delete your local copy of that directory tree and try again.
105:
1.255 joerg 106: 20140530:
107: ARM eABI switched to DWARF based exception handling. This requires
108: rebuilding all C++ code. It is strongly advised to do a clean build.
109:
1.251 martin 110: 20140131:
1.253 joerg 111: The new compiler_rt/libc integration moved a few things. It is strongly
1.254 skrll 112: advised to do a clean build. At least lib/libc, the compat version(s)
1.253 joerg 113: of libc, libkern, rump and the kernels need to be cleaned.
1.251 martin 114:
1.250 christos 115: 20131227:
116: 1. The new ntpd runs in a restricted mode to prevent amplification
117: attacks. If you need ntpdc to work you need to explicitly enable
118: mode7 in your config file. Make sure you put the necessary restrict
119: statements to avoid being exposed.
120: 2. strncat has moved from lib/libc to common/lib/libc; you might need
121: to make clean in libc
122:
1.249 mrg 123: 20131129:
124: The GMP sources were updated, and builds will likely fail without
125: cleaning their build trees for both tools and in-tree, like below.
126:
1.248 mrg 127: 20131128:
128: The MPC and MPFR sources were updated, and builds may require their
129: tools and in-tree directories cleaned for successful updates.
130:
1.246 martin 131: 20130605:
1.247 spz 132: The kernel option FAST_IPSEC no longer exists, it's been renamed
133: to IPSEC (and the older IPSEC version removed).
134:
135: 20130605:
1.246 martin 136: Previous freetype installations eroneously installed private
137: header files. If you are building against a non-empty $DESTDIR,
138: please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
139:
1.245 mrg 140: 20130531:
141: The xdm update may cause build failure due to xdm.man being
142: in the obj tree. Make sure to ensure any like this:
143: nbmake: nbmake: don't know how to make xdm.man. Stop
144: is fixed by deleting the xdm.man in the obj tree.
145:
1.244 mrg 146: 20130530:
147: Updates of many xsrc packages will leave old .pc files around.
148: Best to clean out the xsrc objdir entirely before rebuilds.
149:
1.242 christos 150: 20130301:
151: The removal of netiso requires manual removal of /usr/include/netiso
1.243 christos 152: prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
1.242 christos 153:
1.238 dholland 154: 20120726:
1.241 wiz 155: The update of OpenSSL requires cleaning both the OpenSSL build
156: directory and DESTDIR. *Even non-update builds require cleaning
1.240 dholland 157: DESTDIR.* Builds done without taking these steps may fail, or in
1.241 wiz 158: some cases may succeed and install broken OpenSSL libraries that
1.240 dholland 159: cause third-party software to link incorrectly and/or crash.
1.238 dholland 160:
1.237 wiz 161: 20120507:
1.241 wiz 162: The database schema for makemandb was changed. You will
1.237 wiz 163: need to update the database using 'makemandb -f' or wait
164: for the next weekly run to fix it.
165:
1.236 bsh 166: 20120319:
167: sys/conf/Makefile.kern.inc has been modified to adjust the
168: size of db_symtab automatically. You need to update dbsym in
169: your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
170: you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
171: mk.conf.
172:
1.235 joerg 173: 20120216:
1.241 wiz 174: Default for MKCATPAGES changed to NO. Update builds will fail
175: unless DESTDIR is cleaned manually. If you built between 20120207
1.239 dholland 176: and 20120216, daily and weekly could have created an unreadable
1.241 wiz 177: /var/db/man.db index for apropos. Running makemandb -f or
1.235 joerg 178: the next run of weekly will fix it.
1.233 joerg 179:
1.232 christos 180: 20111227:
181: If you built between 20111225 and 20111227 you need to remove
182: /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
183: bump has been reverted.
184:
1.231 tls 185: 20111125:
186: The "rnd" pseudodevice has been added to sys/conf/std, which
187: means it should no longer be explicitly listed in kernel
188: configuration files. The line "pseudo-device rnd" should be
189: removed from any custom kernel config files users may have.
190:
1.230 tls 191: 20111119:
192: A problem with the datastructures used by the rndctl(8)
193: utility (pointers in datastructures in an array, making 32->64
194: bit compatibility very painful) has been fixed in a
195: non-backwards-compatible way. If you replace your kernel,
196: replace your rndctl executable too.
1.241 wiz 197:
1.229 jym 198: 20111001:
199: the prop_*_send_syscall() functions from proplib(3) have been
200: changed and their new version is not backward compatible with the old
1.241 wiz 201: one. So ensure that all consumers of these functions (currently:
1.229 jym 202: quota2 code and its tests) are updated together with the new lib.
203:
1.228 mrg 204: 20110817:
205: sparc has been changed to use GCC 4.5.3, so any objdir or
206: DESTDIR for them should be deleted before updating.
207:
1.227 riastrad 208: 20110806:
209: i386 and amd64 have been changed to use GCC 4.5.3, so any
210: objdir or DESTDIR for them should be deleted before updating.
211:
1.226 mrg 212: 20110805:
213: The update to GCC 4.5.3 requires a non-trivial portion of
214: the tree to be cleaned. Best to delete both objdir and
215: DESTDIR before running this update. So far, only the
216: sparc64, mips and powerpc platforms have changed.
217:
1.225 matt 218: 20110803:
1.241 wiz 219: The layout of external/public-domain/xz has changed. To do an
1.225 matt 220: update build you will have to remove the contents of the OBJDIR
221: for external/public-domain/xz/bin by hand as the xz entry there
222: is now a directory.
223:
1.223 joerg 224: 20110410:
1.241 wiz 225: The configuration of src/tools/gcc has changed. To do an
1.224 dholland 226: update build you have to clean both tools/binutils and
227: tools/gcc by hand.
1.223 joerg 228:
1.222 plunky 229: 20110328:
230: Building the Xorg binary was moved into a subdirectory to fix
1.241 wiz 231: ordering issues with "make all". It may be necessary to remove
1.222 plunky 232: the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
233: if your update build fails, as the "Xorg" entry there is now a
234: directory.
235:
1.220 joerg 236: 20110121:
1.221 lukem 237: Assembler files no longer use -traditional-cpp. This can break
1.220 joerg 238: the build of individual parts of the tree. This is handled
239: correctly by build.sh. Manual builds have to update /usr/share/mk
240: and re-run config(1) for any kernel configurations as needed.
1.218 joerg 241:
1.217 jruoho 242: 20101217:
243: The tcpdump(8) program was changed to drop privileges and chroot(2)
1.241 wiz 244: by default. It may be necessary to manually update passwd(5) and
1.217 jruoho 245: group(5) in order to make the program work with existing setups.
246:
1.216 christos 247: 20101125:
248: The latest changes to setenv(3) dissallow setting environment
1.241 wiz 249: variables with names that contain '='. Revision 1.18 of env.c
250: assumed that this was allowed. Installing a new libc with an
1.216 christos 251: old copy of /usr/bin/env causes env x=1 printenv | grep x= to
252: break which affects the autoconf tests for dependency finding,
253: so building gcc will end up printing:
254: checking dependency style of gcc... none
255: configure: error: no usable dependency style found
256: Fix it by rebuilding and re-installing env.
1.138 lukem 257:
1.215 mrg 258: 20101119:
259: Recent Xorg updates in xsrc/external/mit/ may cause various build
260: or run-time problems. Delete your entire DESTDIR and OBJDIR if you
261: have any build problems with xsrc, or problems with mismatched
262: versions between xorg-server and drivers.
263:
1.213 jmmv 264: 20100604:
265: The update of ATF to 0.9 causes old tests written in shell to fail
266: unless they are rebuilt. If you are building with MKUPDATE=yes,
267: you need to clean the src/external/bsd/atf/tests/ and the src/tests/
268: trees by hand.
269:
1.211 tnozaki 270: 20100522:
1.212 mrg 271: Recent Xorg updates in xsrc/external/mit/ will cause various build
272: problems. Delete your entire DESTDIR and OBJDIR if you have any
273: build problems with xsrc.
274:
275: 20100522:
1.211 tnozaki 276: private section of <ctype.h> was splitted, and now mklocale(1)
1.214 dholland 277: include ctype_local.h, so you have to make cleandir in tools/mklocale.
1.211 tnozaki 278:
1.210 christos 279: 20100520:
1.241 wiz 280: The location of the xkb compiled descriptions has changed. Please
1.210 christos 281: remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
282:
1.209 njoly 283: 20100222:
284: The shared objects file extension has been changed from .so to
285: .pico, in order to avoid conflicts with shared libraries names
286: libXX.so. All now stale regular .so files can be removed from
287: your object directories.
288:
1.208 roy 289: 20100204:
290: The termcap database has been removed from the sources,
291: but has not been marked obsolete so it is not removed
292: from the system when upgrading.
293: As such, you will need to remove them from your object
294: and destination directories.
295:
1.203 dyoung 296: 20091101:
1.205 dholland 297: After updating, it may be necessary to make the 'cleandir'
298: target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
299: 'build.sh -u tools' or 'build.sh -u distribution'. Ditto
300: src/tools/lex/ and src/usr.bin/lex/.
1.203 dyoung 301:
1.202 mrg 302: 20091001:
1.206 dholland 303: On amd64 you must rebuild tools (to get the new binutils)
304: before building a kernel, or the build fails on cpufunc.S.
305:
306: 20091001:
1.202 mrg 307: An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
308: symlink, failing the build. Delete the link, and the subdir
309: it is in, and retry your build.
310:
1.201 dsl 311: 20090718:
312: libc build changed so that strchr() provides the extra entry
1.241 wiz 313: point for index(). Update build of libc.a (and libc_pic.a)
1.201 dsl 314: may fail because the archive contains the unwanted index.o.
315: (Similarly for strrchr() and rindex().)
316:
1.198 mrg 317: 20090709:
318: Native Xorg was upgraded again. Builds will probably fail again
319: without a clean objdir, at least for src/external/mit/xorg.
320:
1.197 mrg 321: 20090616:
322: Native Xorg was upgraded. Builds will need a clean objdir for
323: src/external/mit/xorg. Upgrading a system from sets will not
324: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
325: subdirectory has been changed into a file, and this needs to
326: be manually "rm -r"'ed before installing xbase.tgz.
327:
1.195 perry 328: 20090501:
329: Several new functions were added to string.h/libc, and this
330: can cause autoconf problems during the tool build for people
1.241 wiz 331: who fail to clean out their tools objects properly. If you
1.195 perry 332: note messages about stpcpy, stpncpy or strnlen accompanying a
333: failure during the tool build, clean out all your tools
334: objects and start again.
335:
1.194 mrg 336: 20090325:
337: The i386 port was switched to i486 default toolchain. This requires
338: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
339:
1.192 skrll 340: 20090126:
1.241 wiz 341: The __posix_fadvise50 system call changed assembly stub type. You
1.207 mbalmer 342: need to 'rm -f __posix_fadvise50.*' in the libc build directory
343: to avoid using the old assembly stub.
1.192 skrll 344:
1.191 joerg 345: 20090202:
346: pkg_install now depends on the pkgdb cache for automatic conflict
347: detection. It is recommented to rebuild the cache with
348: ``pkg_admin rebuild''.
349:
1.184 christos 350: 20090110:
1.241 wiz 351: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
352: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 353: This is needed even in the MODULAR kernel because there is
354: conditionally compiled code in rtsock.c.
1.184 christos 355: 2. make sure build.sh completes and the binaries in a chroot work
356: before installing.
357: 3. If you don't use build.sh and you build directly to root, and
1.241 wiz 358: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 359: are installed properly, and start building libraries first libc
360: and libutil, install them and then continue building all the
1.241 wiz 361: libraries in src/lib and src/gnu/lib and install them. Once
1.184 christos 362: the new libraries are installed, you can restart the build.
363: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 364: rebuild the required packages to update their shared libraries.
365: Any package you rebuild will require rebuilding all the packages
366: that depend on it.
1.186 christos 367: 5. Next time you run pwd_mkdb with the new binary, the file
368: will be upgraded and it will not be backwards compatible.
1.190 apb 369: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
370: lastlogx(5)) have been versioned, and there is a heuristic
1.241 wiz 371: for utmp. You are better off removing the old files after
1.190 apb 372: upgrading. The automated clearing of /var/run during
373: boot, and the automated rotating of files in /var/log by
374: newsyslog(8), may mean that you do not have to remove the
375: files manually.
376: 7. The optional accounting file (/var/account/acct, see
377: accton(8)) has not been versioned, and will need to be
378: removed. The automatic rotation of the accounting file by
379: /etc/daily limits the bad consequences of failure to remove
380: the file.
1.196 dholland 381: 8. Application software that writes time_t to binary files on
1.241 wiz 382: disk will break or need attention. Most notably: if you are
1.196 dholland 383: using PostgreSQL < 8.4, you need to dump your databases,
384: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 385:
1.183 pgoyette 386: 20081219:
387: config(1) has been updated, and one of the files it creates -
388: swapnetbsd.o - has changed format. You need to rebuild config
389: (done automatically by build.sh) and then you need to rerun
390: config on all kernel configuration files before rebuilding those
391: kernels.
392:
1.181 cube 393: 20081205:
394: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
395: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
396: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 397:
1.179 tsutsui 398: 20081122:
1.182 tsutsui 399: On i386, various kernel options(4) in GENERIC including
1.180 wiz 400: file systems have been disabled and moved into kernel modules.
401: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 402: following files as well as a new GENERIC kernel:
403:
404: - build and install kernel modules from src/sys/modules
405:
406: - install the latest bootloader, which will load a module
1.180 wiz 407: for the file system from which the kernel is loaded automatically
1.179 tsutsui 408:
1.180 wiz 409: If you have to load your kernel from a file system which is not of
410: the same type as the root file system, you have to load the necessary
411: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 412:
1.178 lukem 413: 20080827:
414: If you built and installed a libc from sources between
415: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
416: which results in false errors reported by lint(1).
417: Since this breaks the libc build itself, manual help is
1.180 wiz 418: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 419: $ (cd lib/libc && make MKLINT=no dependall install)
420:
1.177 christos 421: 20080813:
422: MKDEBUG build was broken because the .depend files did not know
1.241 wiz 423: about .go files. You need to remove all .depend files and rebuild.
1.177 christos 424:
1.200 dholland 425: 20080802:
426: A regression in binary compatibility for pthread_mutex_t has
1.241 wiz 427: been fixed. Unfortunately, the price is breaking compatibility
1.200 dholland 428: for -current.
429:
430: Threaded programs (using libpthread) and C++ programs (using
431: libstdc++) compiled after 20070907 and before 20080802 need to
432: be recompiled.
433:
434: One way to find affected pkgsrc packages:
435:
436: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
437: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
438:
1.175 simonb 439: 20080731:
440: WAPBL (metadata journaling support) has been added, but at this
441: time isn't backwards compatible with pre-WAPBL aware kernels
442: and userland (fsck_ffs in particular). Please make sure you
443: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 444: especially an uncleanly mounted journaled filesystem. WAPBL
445: also requires the super block to be in the UFS2 format. You
446: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 447:
1.174 lukem 448: 20080721:
449: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
450: isn't defined.
451:
1.173 freza 452: 20080531:
1.241 wiz 453: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
454: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
1.173 freza 455: utility needs to be rebuilt and reinstalled as older binaries
1.241 wiz 456: won't work correctly. The following sequence of commands:
1.173 freza 457:
458: $ (cd sys/sys/ && nbmake-$arch includes)
459: $ (cd sbin/drvctl/ && nbmake-$arch clean)
460: $ (cd sbin/drvctl/ && nbmake-$arch all)
461:
462: leaves new drvctl utility in sbin/drvctl build directory.
463:
1.172 lukem 464: 20080503:
465: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
466:
1.171 he 467: 20080521:
468: For a while, unprivileged UPDATE builds would fail to
469: succeed at the checkflist stage, complaining that
470: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
471: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
472: If you already hit this problem, update the .mk file,
473: remove ${DESTDIR}/stand/<arch>, and re-run the build.
474:
1.174 lukem 475: 20080303:
476: Linker warnings are now fatal if $WARNS>0.
477:
1.170 christos 478: 20080126:
479: The posix_fadvise system call has been changed from an assembly
1.241 wiz 480: stub, to a c file that calls an assembly stub. You need to
1.170 christos 481: 'rm -f posix_fadvise.* .depend' in the libc build directory to
482: avoid using the old assembly stub.
483:
1.168 joerg 484: 20071209:
1.241 wiz 485: The acpiec(4) driver has been split into two attachments. If you
1.168 joerg 486: get ACPI errors before the attachment, please update your kernel
1.169 wiz 487: configuration file appropriately or see GENERIC for more details.
1.168 joerg 488:
1.166 xtraeme 489: 20071115:
490: The it(4) driver has been renamed to itesio(4) and the old port
491: argument specified in the kernel configuration file is not valid
1.241 wiz 492: anymore. The itesio(4) driver now uses the Super I/O address port
493: rather than the EC address port. Please update your kernel
1.167 wiz 494: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 495:
1.165 jmmv 496: 20071028:
497: The pccons(4) driver has been removed from the NetBSD/shark port.
498: You need to update any custom kernel configuration file you have
499: to remove any references to pccons (which includes removing the
500: now useless XSERVER option) and replace them with the correct
501: entries for the wscons driver. See the GENERIC configuration file
502: for more details.
503:
1.164 gdt 504: 20070913:
505: A latent bug in dhclient/dhcpd that caused it to be unable to
506: enumerate interfaces was fixed. The bug began to cause
507: problems after 20070911 when the kernel's SIOCGIFCONF
508: implementation was repaired. From 20070529 to 20070911 racoon
509: could not enumerate interfaces. (These are noted because
510: normal kernel/userspace version matching hygiene is not
511: sufficient to avoid this problem.) Ensure that both kernel
512: and userland are from after 20070913.
513:
1.163 joerg 514: 20070703:
1.241 wiz 515: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
1.199 dholland 516: calls the target-specific strip program, and the logic to pass
517: down STRIP from make has been removed. This requires a
518: re-installation of tools.
1.163 joerg 519:
1.161 dsl 520: 20070422:
521: The way OS emulations lookup filenames inside the emulation root
522: has been changed. Rather than modify the pathname (and copy back
523: to userspace) namei() and lookup() directly check the emulation
1.241 wiz 524: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 525: root file system will be relative to that file system - unless they
1.161 dsl 526: start /../ this is useful when the emulated root is a real install
527: that has such links.
528: This might affect symlinks that have been added to reference outside
529: the emulated root.
530:
1.160 jmcneill 531: 20070412:
1.241 wiz 532: The pckbc driver on sgimips IP32 has been removed. Use macekbc
533: instead. See the GENERIC32_IP3x kernel configuration for an
1.160 jmcneill 534: example.
535:
1.159 gdt 536: 20070319:
537: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
538: on many platforms due to incorrect flags settings. If you
539: updated and built after about 20070315, do "nbmake-$arch
540: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
541: rebuild of object files that might have been built
542: incorrectly, and ensure that you have at least
543: src/lib/libc/Makefile 1.130.
544:
1.241 wiz 545: 20070210:
1.158 dbj 546: src/sys/sys/{sa.h,savar.h} were removed.
547: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
548: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
549: will allow dependencies on those files to get get rebuilt
550:
1.157 apb 551: 20070209:
552: The threading model was changed when the newlock2 branch
553: was merged to NetBSD-current. If you boot with a new
554: kernel (version 4.99.10), then you also need a new pthread
555: library (/usr/lib/libpthread.so.0.7). If you boot with
556: an old kernel, then you need the old pthread library
557: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
558: the pthread library in sync, old threaded applications should
559: continue to work with an old or new kernel. Note that named(8)
560: is the only threaded application in the base system.
561:
1.154 he 562: 20061214:
563: Following the move of string_to_flags() and flags_to_string()
564: from the bin/ls/ sources to libutil, users doing UPDATE builds
565: will need to do a "make cleandir" in
566: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
567: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 568: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
569: as the installation images in distrib/
1.154 he 570: in order to excise stale references to the old stat_flags.h header
571: file in the ls sources -- stat_flags.h has been removed.
572:
1.152 christos 573: 20061108:
574: The configure script used in the src/tools/gcc compiler has been
575: changed to indicate that our libc has ssp support built-in and
1.241 wiz 576: does not depend on -lssp and -lssp-nonshared. You'll need to
1.152 christos 577: make clean in src/tools/gcc first to rebuild the compiler.
578:
1.151 rpaulo 579: 20061009:
580: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
1.241 wiz 581: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
1.151 rpaulo 582:
1.150 bjh21 583: 20060814:
584: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
585: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
586: kernel configuration for an example. X servers from the last
587: few years should cope.
588:
1.149 christos 589: 20060703:
1.241 wiz 590: MPACPI is no more. We always configure PCI interrupts using ACPI
591: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
592: to ACPI_SCANPCI. Thanks to work from fvdl.
1.149 christos 593:
1.148 dogcow 594: 20060627:
595: socket(2) has changed, and its system call has been versioned.
596: For userlands with the old version of socket(2), make sure that
597: your kernel has 'options COMPAT_30' set, or else 'bad system call'
598: errors will result.

1.1 abs 600: Hints for a more successful build:
601: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 602: Use build.sh, but do not use its "expert mode":
1.132 jmmv 603: This will automatically build the tools in the
1.123 jmc 604: correct order, and it will keep the tools and the
605: new build products from interfering with the running
606: system. This will allow you to ignore most of the
607: other advice in this file.
1.2 mrg 608: Build a new kernel first:
609: This makes sure that any new system calls or features
610: expected by the new userland will be present. This
611: helps to avoid critical errors when upgrading.
1.1 abs 612: Use object directories:
613: This helps to keep stale object
614: files from polluting the build if a Makefile "forgets"
615: about one. It also makes it easier to clean up after
616: a build. It's also necessary if you want to use the
617: same source tree for multiple machines.
1.123 jmc 618: To use object directories with build.sh:
619: a) invoke build.sh with the "-M" or "-O" options.
620: To use object directories without using build.sh:
1.1 abs 621: a) cd /usr/src ; make cleandir
1.2 mrg 622: b) Add "OBJMACHINE=yes" to /etc/mk.conf
623: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 624: d) cd /usr/src ; make build
1.2 mrg 625: Note that running "make obj" in a directory will create
626: in obj.$MACHINE directory.
1.1 abs 627: Build to a DESTDIR:
1.123 jmc 628: This helps to keep old installed files (especially libraries)
629: from interfering with the new build.
630: To build to a DESTDIR with build.sh, use the "-D" option.
631: To build to a DESTDIR without using build.sh, set the DESTDIR
632: environment variable before running make build. It should be
633: set to the pathname of an initially empty directory.
634: Problems: if you do not use build.sh, you might need to
635: update critical utilities without using DESTDIR since
636: nothing is executed from what is installed in DESTDIR.
637: (See critical utils, below.)
1.1 abs 638: Build often:
639: This keeps critical utilities current enough to not choke
640: on any other part of the source tree that depends on up to
1.123 jmc 641: date functionality. If you use build.sh, you should not have
642: this problem.
1.241 wiz 643:
1.1 abs 644: What to do if things don't work:
645: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.230 tls 646: When things don't work there are usually a few things that commonly
1.1 abs 647: should be done.
648: 1) make includes
649: This should be done automatically by make build.
650: 2) cd share/mk && make install
651: Again, automatically done by make build.
652:
653: Failsafe rebuild of a small part of the tree:
654: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
655: To make sure you rebuild something correctly you want to do
656: something like the following:
657: 1) Make sure the includes and .mk files are up to date.
658: 2) Make sure any program used to build the particular
659: utility is up to date. (yacc, lex, etc...)
660: 3) cd ...path/to/util...
661: make cleandir
662: rm ...all obj directories...
663: make cleandir # yes, again
664: make obj
665: make depend && make
666:
667: Failsafe rebuild of the entire tree:
668: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
669: If you really want to make sure the source tree is clean and
1.2 mrg 670: ready for a build try the following. Note that sourcing /etc/mk.conf
671: (a make(1) Makefile) in this manner is not right, and will not work
672: for anyone who uses any make(1) features in /etc/mk.conf.
