1.200 ! dholland 1: $NetBSD: UPDATING,v 1.199 2009/07/09 07:50:24 dholland Exp $
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.

16: Recent changes:
17: ^^^^^^^^^^^^^^^
1.138 lukem 18:
1.198 mrg 19: 20090709:
20: Native Xorg was upgraded again. Builds will probably fail again
21: without a clean objdir, at least for src/external/mit/xorg.
22:
1.197 mrg 23: 20090616:
24: Native Xorg was upgraded. Builds will need a clean objdir for
25: src/external/mit/xorg. Upgrading a system from sets will not
26: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
27: subdirectory has been changed into a file, and this needs to
28: be manually "rm -r"'ed before installing xbase.tgz.
29:
1.195 perry 30: 20090501:
31: Several new functions were added to string.h/libc, and this
32: can cause autoconf problems during the tool build for people
33: who fail to clean out their tools objects properly. If you
34: note messages about stpcpy, stpncpy or strnlen accompanying a
35: failure during the tool build, clean out all your tools
36: objects and start again.
37:
1.194 mrg 38: 20090325:
39: The i386 port was switched to i486 default toolchain. This requires
40: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
41:
1.192 skrll 42: 20090126:
1.193 skrll 43: The __posix_fadvise50 system call changed assembly stub type. You need to
44: 'rm -f __posix_fadvise50.*' in the libc build directory to avoid using
1.192 skrll 45: the old assembly stub.
46:
1.191 joerg 47: 20090202:
48: pkg_install now depends on the pkgdb cache for automatic conflict
49: detection. It is recommented to rebuild the cache with
50: ``pkg_admin rebuild''.
51:
1.184 christos 52: 20090110:
53: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
54: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 55: This is needed even in the MODULAR kernel because there is
56: conditionally compiled code in rtsock.c.
1.184 christos 57: 2. make sure build.sh completes and the binaries in a chroot work
58: before installing.
59: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 60: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 61: are installed properly, and start building libraries first libc
62: and libutil, install them and then continue building all the
63: libraries in src/lib and src/gnu/lib and install them. Once
64: the new libraries are installed, you can restart the build.
65: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 66: rebuild the required packages to update their shared libraries.
67: Any package you rebuild will require rebuilding all the packages
68: that depend on it.
1.186 christos 69: 5. Next time you run pwd_mkdb with the new binary, the file
70: will be upgraded and it will not be backwards compatible.
1.190 apb 71: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
72: lastlogx(5)) have been versioned, and there is a heuristic
73: for utmp. You are better off removing the old files after
74: upgrading. The automated clearing of /var/run during
75: boot, and the automated rotating of files in /var/log by
76: newsyslog(8), may mean that you do not have to remove the
77: files manually.
78: 7. The optional accounting file (/var/account/acct, see
79: accton(8)) has not been versioned, and will need to be
80: removed. The automatic rotation of the accounting file by
81: /etc/daily limits the bad consequences of failure to remove
82: the file.
1.196 dholland 83: 8. Application software that writes time_t to binary files on
84: disk will break or need attention. Most notably: if you are
85: using PostgreSQL < 8.4, you need to dump your databases,
86: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 87:
1.183 pgoyette 88: 20081219:
89: config(1) has been updated, and one of the files it creates -
90: swapnetbsd.o - has changed format. You need to rebuild config
91: (done automatically by build.sh) and then you need to rerun
92: config on all kernel configuration files before rebuilding those
93: kernels.
94:
1.181 cube 95: 20081205:
96: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
97: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
98: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 99:
1.179 tsutsui 100: 20081122:
1.182 tsutsui 101: On i386, various kernel options(4) in GENERIC including
1.180 wiz 102: file systems have been disabled and moved into kernel modules.
103: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 104: following files as well as a new GENERIC kernel:
105:
106: - build and install kernel modules from src/sys/modules
107:
108: - install the latest bootloader, which will load a module
1.180 wiz 109: for the file system from which the kernel is loaded automatically
1.179 tsutsui 110:
1.180 wiz 111: If you have to load your kernel from a file system which is not of
112: the same type as the root file system, you have to load the necessary
113: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 114:
1.178 lukem 115: 20080827:
116: If you built and installed a libc from sources between
117: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
118: which results in false errors reported by lint(1).
119: Since this breaks the libc build itself, manual help is
1.180 wiz 120: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 121: $ (cd lib/libc && make MKLINT=no dependall install)
122:
1.177 christos 123: 20080813:
124: MKDEBUG build was broken because the .depend files did not know
125: about .go files. You need to remove all .depend files and rebuild.
126:
1.200 ! dholland 127: 20080802:
! 128: A regression in binary compatibility for pthread_mutex_t has
! 129: been fixed. Unfortunately, the price is breaking compatibility
! 130: for -current.
! 131:
! 132: Threaded programs (using libpthread) and C++ programs (using
! 133: libstdc++) compiled after 20070907 and before 20080802 need to
! 134: be recompiled.
! 135:
! 136: One way to find affected pkgsrc packages:
! 137:
! 138: $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
! 139: $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
! 140:
1.175 simonb 141: 20080731:
142: WAPBL (metadata journaling support) has been added, but at this
143: time isn't backwards compatible with pre-WAPBL aware kernels
144: and userland (fsck_ffs in particular). Please make sure you
145: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 146: especially an uncleanly mounted journaled filesystem. WAPBL
147: also requires the super block to be in the UFS2 format. You
148: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 149:
1.174 lukem 150: 20080721:
151: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
152: isn't defined.
153:
1.173 freza 154: 20080531:
155: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
156: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
157: utility needs to be rebuilt and reinstalled as older binaries
158: won't work correctly. The following sequence of commands:
159:
160: $ (cd sys/sys/ && nbmake-$arch includes)
161: $ (cd sbin/drvctl/ && nbmake-$arch clean)
162: $ (cd sbin/drvctl/ && nbmake-$arch all)
163:
164: leaves new drvctl utility in sbin/drvctl build directory.
165:
1.172 lukem 166: 20080503:
167: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
168:
1.171 he 169: 20080521:
170: For a while, unprivileged UPDATE builds would fail to
171: succeed at the checkflist stage, complaining that
172: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
173: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
174: If you already hit this problem, update the .mk file,
175: remove ${DESTDIR}/stand/<arch>, and re-run the build.
176:
1.174 lukem 177: 20080303:
178: Linker warnings are now fatal if $WARNS>0.
179:
1.170 christos 180: 20080126:
181: The posix_fadvise system call has been changed from an assembly
182: stub, to a c file that calls an assembly stub. You need to
183: 'rm -f posix_fadvise.* .depend' in the libc build directory to
184: avoid using the old assembly stub.
185:
1.168 joerg 186: 20071209:
187: The acpiec(4) driver has been split into two attachments. If you
188: get ACPI errors before the attachment, please update your kernel
1.169 wiz 189: configuration file appropriately or see GENERIC for more details.
1.168 joerg 190:
1.166 xtraeme 191: 20071115:
192: The it(4) driver has been renamed to itesio(4) and the old port
193: argument specified in the kernel configuration file is not valid
194: anymore. The itesio(4) driver now uses the Super I/O address port
195: rather than the EC address port. Please update your kernel
1.167 wiz 196: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 197:
1.165 jmmv 198: 20071028:
199: The pccons(4) driver has been removed from the NetBSD/shark port.
200: You need to update any custom kernel configuration file you have
201: to remove any references to pccons (which includes removing the
202: now useless XSERVER option) and replace them with the correct
203: entries for the wscons driver. See the GENERIC configuration file
204: for more details.
205:
1.164 gdt 206: 20070913:
207: A latent bug in dhclient/dhcpd that caused it to be unable to
208: enumerate interfaces was fixed. The bug began to cause
209: problems after 20070911 when the kernel's SIOCGIFCONF
210: implementation was repaired. From 20070529 to 20070911 racoon
211: could not enumerate interfaces. (These are noted because
212: normal kernel/userspace version matching hygiene is not
213: sufficient to avoid this problem.) Ensure that both kernel
214: and userland are from after 20070913.
215:
1.163 joerg 216: 20070703:
1.199 dholland 217: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
218: calls the target-specific strip program, and the logic to pass
219: down STRIP from make has been removed. This requires a
220: re-installation of tools.
1.163 joerg 221:
1.161 dsl 222: 20070422:
223: The way OS emulations lookup filenames inside the emulation root
224: has been changed. Rather than modify the pathname (and copy back
225: to userspace) namei() and lookup() directly check the emulation
226: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 227: root file system will be relative to that file system - unless they
1.161 dsl 228: start /../ this is useful when the emulated root is a real install
229: that has such links.
230: This might affect symlinks that have been added to reference outside
231: the emulated root.
232:
1.160 jmcneill 233: 20070412:
234: The pckbc driver on sgimips IP32 has been removed. Use macekbc
235: instead. See the GENERIC32_IP3x kernel configuration for an
236: example.
237:
1.159 gdt 238: 20070319:
239: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
240: on many platforms due to incorrect flags settings. If you
241: updated and built after about 20070315, do "nbmake-$arch
242: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
243: rebuild of object files that might have been built
244: incorrectly, and ensure that you have at least
245: src/lib/libc/Makefile 1.130.
246:
1.158 dbj 247: 20070210:
248: src/sys/sys/{sa.h,savar.h} were removed.
249: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
250: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
251: will allow dependencies on those files to get get rebuilt
252:
1.157 apb 253: 20070209:
254: The threading model was changed when the newlock2 branch
255: was merged to NetBSD-current. If you boot with a new
256: kernel (version 4.99.10), then you also need a new pthread
257: library (/usr/lib/libpthread.so.0.7). If you boot with
258: an old kernel, then you need the old pthread library
259: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
260: the pthread library in sync, old threaded applications should
261: continue to work with an old or new kernel. Note that named(8)
262: is the only threaded application in the base system.
263:
1.154 he 264: 20061214:
265: Following the move of string_to_flags() and flags_to_string()
266: from the bin/ls/ sources to libutil, users doing UPDATE builds
267: will need to do a "make cleandir" in
268: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
269: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 270: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
271: as the installation images in distrib/
1.154 he 272: in order to excise stale references to the old stat_flags.h header
273: file in the ls sources -- stat_flags.h has been removed.
274:
1.152 christos 275: 20061108:
276: The configure script used in the src/tools/gcc compiler has been
277: changed to indicate that our libc has ssp support built-in and
278: does not depend on -lssp and -lssp-nonshared. You'll need to
279: make clean in src/tools/gcc first to rebuild the compiler.
280:
1.151 rpaulo 281: 20061009:
282: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
283: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
284:
1.150 bjh21 285: 20060814:
286: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
287: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
288: kernel configuration for an example. X servers from the last
289: few years should cope.
290:
1.149 christos 291: 20060703:
292: MPACPI is no more. We always configure PCI interrupts using ACPI
293: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
294: to ACPI_SCANPCI. Thanks to work from fvdl.
295:
1.148 dogcow 296: 20060627:
297: socket(2) has changed, and its system call has been versioned.
298: For userlands with the old version of socket(2), make sure that
299: your kernel has 'options COMPAT_30' set, or else 'bad system call'
300: errors will result.
301:
1.1 abs 302: Hints for a more successful build:
303: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 304: Use build.sh, but do not use its "expert mode":
1.132 jmmv 305: This will automatically build the tools in the
1.123 jmc 306: correct order, and it will keep the tools and the
307: new build products from interfering with the running
308: system. This will allow you to ignore most of the
309: other advice in this file.
1.2 mrg 310: Build a new kernel first:
311: This makes sure that any new system calls or features
312: expected by the new userland will be present. This
313: helps to avoid critical errors when upgrading.
1.1 abs 314: Use object directories:
315: This helps to keep stale object
316: files from polluting the build if a Makefile "forgets"
317: about one. It also makes it easier to clean up after
318: a build. It's also necessary if you want to use the
319: same source tree for multiple machines.
1.123 jmc 320: To use object directories with build.sh:
321: a) invoke build.sh with the "-M" or "-O" options.
322: To use object directories without using build.sh:
1.1 abs 323: a) cd /usr/src ; make cleandir
1.2 mrg 324: b) Add "OBJMACHINE=yes" to /etc/mk.conf
325: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 326: d) cd /usr/src ; make build
1.2 mrg 327: Note that running "make obj" in a directory will create
328: in obj.$MACHINE directory.
1.1 abs 329: Build to a DESTDIR:
1.123 jmc 330: This helps to keep old installed files (especially libraries)
331: from interfering with the new build.
332: To build to a DESTDIR with build.sh, use the "-D" option.
333: To build to a DESTDIR without using build.sh, set the DESTDIR
334: environment variable before running make build. It should be
335: set to the pathname of an initially empty directory.
336: Problems: if you do not use build.sh, you might need to
337: update critical utilities without using DESTDIR since
338: nothing is executed from what is installed in DESTDIR.
339: (See critical utils, below.)
1.1 abs 340: Build often:
341: This keeps critical utilities current enough to not choke
342: on any other part of the source tree that depends on up to
1.123 jmc 343: date functionality. If you use build.sh, you should not have
344: this problem.
1.1 abs 345:
346: What to do if things don't work:
347: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
348: When things don't work there is usually a few things that commonly
349: should be done.
350: 1) make includes
351: This should be done automatically by make build.
352: 2) cd share/mk && make install
353: Again, automatically done by make build.
354:
355: Failsafe rebuild of a small part of the tree:
356: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
357: To make sure you rebuild something correctly you want to do
358: something like the following:
359: 1) Make sure the includes and .mk files are up to date.
360: 2) Make sure any program used to build the particular
361: utility is up to date. (yacc, lex, etc...)
362: 3) cd ...path/to/util...
363: make cleandir
364: rm ...all obj directories...
365: make cleandir # yes, again
366: make obj
367: make depend && make
368:
369: Failsafe rebuild of the entire tree:
370: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
371: If you really want to make sure the source tree is clean and
1.2 mrg 372: ready for a build try the following. Note that sourcing /etc/mk.conf
373: (a make(1) Makefile) in this manner is not right, and will not work
374: for anyone who uses any make(1) features in /etc/mk.conf.
