1.191 ! joerg 1: $NetBSD: UPDATING,v 1.190 2009/01/21 14:19:58 apb 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.

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