1.197 ! mrg 1: $NetBSD: UPDATING,v 1.196 2009/05/27 18:02:57 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:
1.197 ! mrg 19: 20090616:
! 20: Native Xorg was upgraded. Builds will need a clean objdir for
! 21: src/external/mit/xorg. Upgrading a system from sets will not
! 22: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
! 23: subdirectory has been changed into a file, and this needs to
! 24: be manually "rm -r"'ed before installing xbase.tgz.
! 25:
1.195 perry 26: 20090501:
27: Several new functions were added to string.h/libc, and this
28: can cause autoconf problems during the tool build for people
29: who fail to clean out their tools objects properly. If you
30: note messages about stpcpy, stpncpy or strnlen accompanying a
31: failure during the tool build, clean out all your tools
32: objects and start again.
33:
1.194 mrg 34: 20090325:
35: The i386 port was switched to i486 default toolchain. This requires
36: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
37:
1.192 skrll 38: 20090126:
1.193 skrll 39: The __posix_fadvise50 system call changed assembly stub type. You need to
40: 'rm -f __posix_fadvise50.*' in the libc build directory to avoid using
1.192 skrll 41: the old assembly stub.
42:
1.191 joerg 43: 20090202:
44: pkg_install now depends on the pkgdb cache for automatic conflict
45: detection. It is recommented to rebuild the cache with
46: ``pkg_admin rebuild''.
47:
1.184 christos 48: 20090110:
49: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
50: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 51: This is needed even in the MODULAR kernel because there is
52: conditionally compiled code in rtsock.c.
1.184 christos 53: 2. make sure build.sh completes and the binaries in a chroot work
54: before installing.
55: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 56: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 57: are installed properly, and start building libraries first libc
58: and libutil, install them and then continue building all the
59: libraries in src/lib and src/gnu/lib and install them. Once
60: the new libraries are installed, you can restart the build.
61: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 62: rebuild the required packages to update their shared libraries.
63: Any package you rebuild will require rebuilding all the packages
64: that depend on it.
1.186 christos 65: 5. Next time you run pwd_mkdb with the new binary, the file
66: will be upgraded and it will not be backwards compatible.
1.190 apb 67: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
68: lastlogx(5)) have been versioned, and there is a heuristic
69: for utmp. You are better off removing the old files after
70: upgrading. The automated clearing of /var/run during
71: boot, and the automated rotating of files in /var/log by
72: newsyslog(8), may mean that you do not have to remove the
73: files manually.
74: 7. The optional accounting file (/var/account/acct, see
75: accton(8)) has not been versioned, and will need to be
76: removed. The automatic rotation of the accounting file by
77: /etc/daily limits the bad consequences of failure to remove
78: the file.
1.196 dholland 79: 8. Application software that writes time_t to binary files on
80: disk will break or need attention. Most notably: if you are
81: using PostgreSQL < 8.4, you need to dump your databases,
82: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 83:
1.183 pgoyette 84: 20081219:
85: config(1) has been updated, and one of the files it creates -
86: swapnetbsd.o - has changed format. You need to rebuild config
87: (done automatically by build.sh) and then you need to rerun
88: config on all kernel configuration files before rebuilding those
89: kernels.
90:
1.181 cube 91: 20081205:
92: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
93: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
94: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 95:
1.179 tsutsui 96: 20081122:
1.182 tsutsui 97: On i386, various kernel options(4) in GENERIC including
1.180 wiz 98: file systems have been disabled and moved into kernel modules.
99: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 100: following files as well as a new GENERIC kernel:
101:
102: - build and install kernel modules from src/sys/modules
103:
104: - install the latest bootloader, which will load a module
1.180 wiz 105: for the file system from which the kernel is loaded automatically
1.179 tsutsui 106:
1.180 wiz 107: If you have to load your kernel from a file system which is not of
108: the same type as the root file system, you have to load the necessary
109: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 110:
1.178 lukem 111: 20080827:
112: If you built and installed a libc from sources between
113: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
114: which results in false errors reported by lint(1).
115: Since this breaks the libc build itself, manual help is
1.180 wiz 116: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 117: $ (cd lib/libc && make MKLINT=no dependall install)
118:
1.177 christos 119: 20080813:
120: MKDEBUG build was broken because the .depend files did not know
121: about .go files. You need to remove all .depend files and rebuild.
122:
1.175 simonb 123: 20080731:
124: WAPBL (metadata journaling support) has been added, but at this
125: time isn't backwards compatible with pre-WAPBL aware kernels
126: and userland (fsck_ffs in particular). Please make sure you
127: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 128: especially an uncleanly mounted journaled filesystem. WAPBL
129: also requires the super block to be in the UFS2 format. You
130: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 131:
1.174 lukem 132: 20080721:
133: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
134: isn't defined.
135:
1.173 freza 136: 20080531:
137: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
138: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
139: utility needs to be rebuilt and reinstalled as older binaries
140: won't work correctly. The following sequence of commands:
141:
142: $ (cd sys/sys/ && nbmake-$arch includes)
143: $ (cd sbin/drvctl/ && nbmake-$arch clean)
144: $ (cd sbin/drvctl/ && nbmake-$arch all)
145:
146: leaves new drvctl utility in sbin/drvctl build directory.
147:
1.172 lukem 148: 20080503:
149: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
150:
1.171 he 151: 20080521:
152: For a while, unprivileged UPDATE builds would fail to
153: succeed at the checkflist stage, complaining that
154: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
155: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
156: If you already hit this problem, update the .mk file,
157: remove ${DESTDIR}/stand/<arch>, and re-run the build.
158:
1.174 lukem 159: 20080303:
160: Linker warnings are now fatal if $WARNS>0.
161:
1.170 christos 162: 20080126:
163: The posix_fadvise system call has been changed from an assembly
164: stub, to a c file that calls an assembly stub. You need to
165: 'rm -f posix_fadvise.* .depend' in the libc build directory to
166: avoid using the old assembly stub.
167:
1.168 joerg 168: 20071209:
169: The acpiec(4) driver has been split into two attachments. If you
170: get ACPI errors before the attachment, please update your kernel
1.169 wiz 171: configuration file appropriately or see GENERIC for more details.
1.168 joerg 172:
1.166 xtraeme 173: 20071115:
174: The it(4) driver has been renamed to itesio(4) and the old port
175: argument specified in the kernel configuration file is not valid
176: anymore. The itesio(4) driver now uses the Super I/O address port
177: rather than the EC address port. Please update your kernel
1.167 wiz 178: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 179:
1.165 jmmv 180: 20071028:
181: The pccons(4) driver has been removed from the NetBSD/shark port.
182: You need to update any custom kernel configuration file you have
183: to remove any references to pccons (which includes removing the
184: now useless XSERVER option) and replace them with the correct
185: entries for the wscons driver. See the GENERIC configuration file
186: for more details.
187:
1.164 gdt 188: 20070913:
189: A latent bug in dhclient/dhcpd that caused it to be unable to
190: enumerate interfaces was fixed. The bug began to cause
191: problems after 20070911 when the kernel's SIOCGIFCONF
192: implementation was repaired. From 20070529 to 20070911 racoon
193: could not enumerate interfaces. (These are noted because
194: normal kernel/userspace version matching hygiene is not
195: sufficient to avoid this problem.) Ensure that both kernel
196: and userland are from after 20070913.
197:
1.163 joerg 198: 20070703:
199: nbinstall has been renamed as it calls the target specific and
200: the logic to pass down STRIP from mk been removed. This forces
201: a re-installation of tools.
202:
1.161 dsl 203: 20070422:
204: The way OS emulations lookup filenames inside the emulation root
205: has been changed. Rather than modify the pathname (and copy back
206: to userspace) namei() and lookup() directly check the emulation
207: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 208: root file system will be relative to that file system - unless they
1.161 dsl 209: start /../ this is useful when the emulated root is a real install
210: that has such links.
211: This might affect symlinks that have been added to reference outside
212: the emulated root.
213:
1.160 jmcneill 214: 20070412:
215: The pckbc driver on sgimips IP32 has been removed. Use macekbc
216: instead. See the GENERIC32_IP3x kernel configuration for an
217: example.
218:
1.159 gdt 219: 20070319:
220: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
221: on many platforms due to incorrect flags settings. If you
222: updated and built after about 20070315, do "nbmake-$arch
223: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
224: rebuild of object files that might have been built
225: incorrectly, and ensure that you have at least
226: src/lib/libc/Makefile 1.130.
227:
1.158 dbj 228: 20070210:
229: src/sys/sys/{sa.h,savar.h} were removed.
230: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
231: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
232: will allow dependencies on those files to get get rebuilt
233:
1.157 apb 234: 20070209:
235: The threading model was changed when the newlock2 branch
236: was merged to NetBSD-current. If you boot with a new
237: kernel (version 4.99.10), then you also need a new pthread
238: library (/usr/lib/libpthread.so.0.7). If you boot with
239: an old kernel, then you need the old pthread library
240: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
241: the pthread library in sync, old threaded applications should
242: continue to work with an old or new kernel. Note that named(8)
243: is the only threaded application in the base system.
244:
1.154 he 245: 20061214:
246: Following the move of string_to_flags() and flags_to_string()
247: from the bin/ls/ sources to libutil, users doing UPDATE builds
248: will need to do a "make cleandir" in
249: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
250: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 251: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
252: as the installation images in distrib/
1.154 he 253: in order to excise stale references to the old stat_flags.h header
254: file in the ls sources -- stat_flags.h has been removed.
255:
1.152 christos 256: 20061108:
257: The configure script used in the src/tools/gcc compiler has been
258: changed to indicate that our libc has ssp support built-in and
259: does not depend on -lssp and -lssp-nonshared. You'll need to
260: make clean in src/tools/gcc first to rebuild the compiler.
261:
1.151 rpaulo 262: 20061009:
263: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
264: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
265:
1.150 bjh21 266: 20060814:
267: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
268: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
269: kernel configuration for an example. X servers from the last
270: few years should cope.
271:
1.149 christos 272: 20060703:
273: MPACPI is no more. We always configure PCI interrupts using ACPI
274: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
275: to ACPI_SCANPCI. Thanks to work from fvdl.
276:
1.148 dogcow 277: 20060627:
278: socket(2) has changed, and its system call has been versioned.
279: For userlands with the old version of socket(2), make sure that
280: your kernel has 'options COMPAT_30' set, or else 'bad system call'
281: errors will result.
282:
1.1 abs 283: Hints for a more successful build:
284: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 285: Use build.sh, but do not use its "expert mode":
1.132 jmmv 286: This will automatically build the tools in the
1.123 jmc 287: correct order, and it will keep the tools and the
288: new build products from interfering with the running
289: system. This will allow you to ignore most of the
290: other advice in this file.
1.2 mrg 291: Build a new kernel first:
292: This makes sure that any new system calls or features
293: expected by the new userland will be present. This
294: helps to avoid critical errors when upgrading.
1.1 abs 295: Use object directories:
296: This helps to keep stale object
297: files from polluting the build if a Makefile "forgets"
298: about one. It also makes it easier to clean up after
299: a build. It's also necessary if you want to use the
300: same source tree for multiple machines.
1.123 jmc 301: To use object directories with build.sh:
302: a) invoke build.sh with the "-M" or "-O" options.
303: To use object directories without using build.sh:
1.1 abs 304: a) cd /usr/src ; make cleandir
1.2 mrg 305: b) Add "OBJMACHINE=yes" to /etc/mk.conf
306: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 307: d) cd /usr/src ; make build
1.2 mrg 308: Note that running "make obj" in a directory will create
309: in obj.$MACHINE directory.
1.1 abs 310: Build to a DESTDIR:
1.123 jmc 311: This helps to keep old installed files (especially libraries)
312: from interfering with the new build.
313: To build to a DESTDIR with build.sh, use the "-D" option.
314: To build to a DESTDIR without using build.sh, set the DESTDIR
315: environment variable before running make build. It should be
316: set to the pathname of an initially empty directory.
317: Problems: if you do not use build.sh, you might need to
318: update critical utilities without using DESTDIR since
319: nothing is executed from what is installed in DESTDIR.
320: (See critical utils, below.)
1.1 abs 321: Build often:
322: This keeps critical utilities current enough to not choke
323: on any other part of the source tree that depends on up to
1.123 jmc 324: date functionality. If you use build.sh, you should not have
325: this problem.
1.1 abs 326:
327: What to do if things don't work:
328: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
329: When things don't work there is usually a few things that commonly
330: should be done.
331: 1) make includes
332: This should be done automatically by make build.
333: 2) cd share/mk && make install
334: Again, automatically done by make build.
335:
336: Failsafe rebuild of a small part of the tree:
337: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
338: To make sure you rebuild something correctly you want to do
339: something like the following:
340: 1) Make sure the includes and .mk files are up to date.
341: 2) Make sure any program used to build the particular
342: utility is up to date. (yacc, lex, etc...)
343: 3) cd ...path/to/util...
344: make cleandir
345: rm ...all obj directories...
346: make cleandir # yes, again
347: make obj
348: make depend && make
349:
350: Failsafe rebuild of the entire tree:
351: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
352: If you really want to make sure the source tree is clean and
1.2 mrg 353: ready for a build try the following. Note that sourcing /etc/mk.conf
354: (a make(1) Makefile) in this manner is not right, and will not work
355: for anyone who uses any make(1) features in /etc/mk.conf.
