1.196 ! dholland 1: $NetBSD: UPDATING,v 1.195 2009/05/01 23:08:25 perry 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:
1.195 perry 19: 20090501:
20: Several new functions were added to string.h/libc, and this
21: can cause autoconf problems during the tool build for people
22: who fail to clean out their tools objects properly. If you
23: note messages about stpcpy, stpncpy or strnlen accompanying a
24: failure during the tool build, clean out all your tools
25: objects and start again.
26:
1.194 mrg 27: 20090325:
28: The i386 port was switched to i486 default toolchain. This requires
29: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
30:
1.192 skrll 31: 20090126:
1.193 skrll 32: The __posix_fadvise50 system call changed assembly stub type. You need to
33: 'rm -f __posix_fadvise50.*' in the libc build directory to avoid using
1.192 skrll 34: the old assembly stub.
35:
1.191 joerg 36: 20090202:
37: pkg_install now depends on the pkgdb cache for automatic conflict
38: detection. It is recommented to rebuild the cache with
39: ``pkg_admin rebuild''.
40:
1.184 christos 41: 20090110:
42: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
43: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 44: This is needed even in the MODULAR kernel because there is
45: conditionally compiled code in rtsock.c.
1.184 christos 46: 2. make sure build.sh completes and the binaries in a chroot work
47: before installing.
48: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 49: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 50: are installed properly, and start building libraries first libc
51: and libutil, install them and then continue building all the
52: libraries in src/lib and src/gnu/lib and install them. Once
53: the new libraries are installed, you can restart the build.
54: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 55: rebuild the required packages to update their shared libraries.
56: Any package you rebuild will require rebuilding all the packages
57: that depend on it.
1.186 christos 58: 5. Next time you run pwd_mkdb with the new binary, the file
59: will be upgraded and it will not be backwards compatible.
1.190 apb 60: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
61: lastlogx(5)) have been versioned, and there is a heuristic
62: for utmp. You are better off removing the old files after
63: upgrading. The automated clearing of /var/run during
64: boot, and the automated rotating of files in /var/log by
65: newsyslog(8), may mean that you do not have to remove the
66: files manually.
67: 7. The optional accounting file (/var/account/acct, see
68: accton(8)) has not been versioned, and will need to be
69: removed. The automatic rotation of the accounting file by
70: /etc/daily limits the bad consequences of failure to remove
71: the file.
1.196 ! dholland 72: 8. Application software that writes time_t to binary files on
! 73: disk will break or need attention. Most notably: if you are
! 74: using PostgreSQL < 8.4, you need to dump your databases,
! 75: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 76:
1.183 pgoyette 77: 20081219:
78: config(1) has been updated, and one of the files it creates -
79: swapnetbsd.o - has changed format. You need to rebuild config
80: (done automatically by build.sh) and then you need to rerun
81: config on all kernel configuration files before rebuilding those
82: kernels.
83:
1.181 cube 84: 20081205:
85: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
86: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
87: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 88:
1.179 tsutsui 89: 20081122:
1.182 tsutsui 90: On i386, various kernel options(4) in GENERIC including
1.180 wiz 91: file systems have been disabled and moved into kernel modules.
92: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 93: following files as well as a new GENERIC kernel:
94:
95: - build and install kernel modules from src/sys/modules
96:
97: - install the latest bootloader, which will load a module
1.180 wiz 98: for the file system from which the kernel is loaded automatically
1.179 tsutsui 99:
1.180 wiz 100: If you have to load your kernel from a file system which is not of
101: the same type as the root file system, you have to load the necessary
102: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 103:
1.178 lukem 104: 20080827:
105: If you built and installed a libc from sources between
106: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
107: which results in false errors reported by lint(1).
108: Since this breaks the libc build itself, manual help is
1.180 wiz 109: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 110: $ (cd lib/libc && make MKLINT=no dependall install)
111:
1.177 christos 112: 20080813:
113: MKDEBUG build was broken because the .depend files did not know
114: about .go files. You need to remove all .depend files and rebuild.
115:
1.175 simonb 116: 20080731:
117: WAPBL (metadata journaling support) has been added, but at this
118: time isn't backwards compatible with pre-WAPBL aware kernels
119: and userland (fsck_ffs in particular). Please make sure you
120: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 121: especially an uncleanly mounted journaled filesystem. WAPBL
122: also requires the super block to be in the UFS2 format. You
123: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 124:
1.174 lukem 125: 20080721:
126: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
127: isn't defined.
128:
1.173 freza 129: 20080531:
130: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
131: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
132: utility needs to be rebuilt and reinstalled as older binaries
133: won't work correctly. The following sequence of commands:
134:
135: $ (cd sys/sys/ && nbmake-$arch includes)
136: $ (cd sbin/drvctl/ && nbmake-$arch clean)
137: $ (cd sbin/drvctl/ && nbmake-$arch all)
138:
139: leaves new drvctl utility in sbin/drvctl build directory.
140:
1.172 lukem 141: 20080503:
142: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
143:
1.171 he 144: 20080521:
145: For a while, unprivileged UPDATE builds would fail to
146: succeed at the checkflist stage, complaining that
147: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
148: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
149: If you already hit this problem, update the .mk file,
150: remove ${DESTDIR}/stand/<arch>, and re-run the build.
151:
1.174 lukem 152: 20080303:
153: Linker warnings are now fatal if $WARNS>0.
154:
1.170 christos 155: 20080126:
156: The posix_fadvise system call has been changed from an assembly
157: stub, to a c file that calls an assembly stub. You need to
158: 'rm -f posix_fadvise.* .depend' in the libc build directory to
159: avoid using the old assembly stub.
160:
1.168 joerg 161: 20071209:
162: The acpiec(4) driver has been split into two attachments. If you
163: get ACPI errors before the attachment, please update your kernel
1.169 wiz 164: configuration file appropriately or see GENERIC for more details.
1.168 joerg 165:
1.166 xtraeme 166: 20071115:
167: The it(4) driver has been renamed to itesio(4) and the old port
168: argument specified in the kernel configuration file is not valid
169: anymore. The itesio(4) driver now uses the Super I/O address port
170: rather than the EC address port. Please update your kernel
1.167 wiz 171: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 172:
1.165 jmmv 173: 20071028:
174: The pccons(4) driver has been removed from the NetBSD/shark port.
175: You need to update any custom kernel configuration file you have
176: to remove any references to pccons (which includes removing the
177: now useless XSERVER option) and replace them with the correct
178: entries for the wscons driver. See the GENERIC configuration file
179: for more details.
180:
1.164 gdt 181: 20070913:
182: A latent bug in dhclient/dhcpd that caused it to be unable to
183: enumerate interfaces was fixed. The bug began to cause
184: problems after 20070911 when the kernel's SIOCGIFCONF
185: implementation was repaired. From 20070529 to 20070911 racoon
186: could not enumerate interfaces. (These are noted because
187: normal kernel/userspace version matching hygiene is not
188: sufficient to avoid this problem.) Ensure that both kernel
189: and userland are from after 20070913.
190:
1.163 joerg 191: 20070703:
192: nbinstall has been renamed as it calls the target specific and
193: the logic to pass down STRIP from mk been removed. This forces
194: a re-installation of tools.
195:
1.161 dsl 196: 20070422:
197: The way OS emulations lookup filenames inside the emulation root
198: has been changed. Rather than modify the pathname (and copy back
199: to userspace) namei() and lookup() directly check the emulation
200: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 201: root file system will be relative to that file system - unless they
1.161 dsl 202: start /../ this is useful when the emulated root is a real install
203: that has such links.
204: This might affect symlinks that have been added to reference outside
205: the emulated root.
206:
1.160 jmcneill 207: 20070412:
208: The pckbc driver on sgimips IP32 has been removed. Use macekbc
209: instead. See the GENERIC32_IP3x kernel configuration for an
210: example.
211:
1.159 gdt 212: 20070319:
213: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
214: on many platforms due to incorrect flags settings. If you
215: updated and built after about 20070315, do "nbmake-$arch
216: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
217: rebuild of object files that might have been built
218: incorrectly, and ensure that you have at least
219: src/lib/libc/Makefile 1.130.
220:
1.158 dbj 221: 20070210:
222: src/sys/sys/{sa.h,savar.h} were removed.
223: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
224: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
225: will allow dependencies on those files to get get rebuilt
226:
1.157 apb 227: 20070209:
228: The threading model was changed when the newlock2 branch
229: was merged to NetBSD-current. If you boot with a new
230: kernel (version 4.99.10), then you also need a new pthread
231: library (/usr/lib/libpthread.so.0.7). If you boot with
232: an old kernel, then you need the old pthread library
233: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
234: the pthread library in sync, old threaded applications should
235: continue to work with an old or new kernel. Note that named(8)
236: is the only threaded application in the base system.
237:
1.154 he 238: 20061214:
239: Following the move of string_to_flags() and flags_to_string()
240: from the bin/ls/ sources to libutil, users doing UPDATE builds
241: will need to do a "make cleandir" in
242: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
243: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 244: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
245: as the installation images in distrib/
1.154 he 246: in order to excise stale references to the old stat_flags.h header
247: file in the ls sources -- stat_flags.h has been removed.
248:
1.152 christos 249: 20061108:
250: The configure script used in the src/tools/gcc compiler has been
251: changed to indicate that our libc has ssp support built-in and
252: does not depend on -lssp and -lssp-nonshared. You'll need to
253: make clean in src/tools/gcc first to rebuild the compiler.
254:
1.151 rpaulo 255: 20061009:
256: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
257: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
258:
1.150 bjh21 259: 20060814:
260: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
261: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
262: kernel configuration for an example. X servers from the last
263: few years should cope.
264:
1.149 christos 265: 20060703:
266: MPACPI is no more. We always configure PCI interrupts using ACPI
267: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
268: to ACPI_SCANPCI. Thanks to work from fvdl.
269:
1.148 dogcow 270: 20060627:
271: socket(2) has changed, and its system call has been versioned.
272: For userlands with the old version of socket(2), make sure that
273: your kernel has 'options COMPAT_30' set, or else 'bad system call'
274: errors will result.
275:
1.1 abs 276: Hints for a more successful build:
277: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 278: Use build.sh, but do not use its "expert mode":
1.132 jmmv 279: This will automatically build the tools in the
1.123 jmc 280: correct order, and it will keep the tools and the
281: new build products from interfering with the running
282: system. This will allow you to ignore most of the
283: other advice in this file.
1.2 mrg 284: Build a new kernel first:
285: This makes sure that any new system calls or features
286: expected by the new userland will be present. This
287: helps to avoid critical errors when upgrading.
1.1 abs 288: Use object directories:
289: This helps to keep stale object
290: files from polluting the build if a Makefile "forgets"
291: about one. It also makes it easier to clean up after
292: a build. It's also necessary if you want to use the
293: same source tree for multiple machines.
1.123 jmc 294: To use object directories with build.sh:
295: a) invoke build.sh with the "-M" or "-O" options.
296: To use object directories without using build.sh:
1.1 abs 297: a) cd /usr/src ; make cleandir
1.2 mrg 298: b) Add "OBJMACHINE=yes" to /etc/mk.conf
299: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 300: d) cd /usr/src ; make build
1.2 mrg 301: Note that running "make obj" in a directory will create
302: in obj.$MACHINE directory.
1.1 abs 303: Build to a DESTDIR:
1.123 jmc 304: This helps to keep old installed files (especially libraries)
305: from interfering with the new build.
306: To build to a DESTDIR with build.sh, use the "-D" option.
307: To build to a DESTDIR without using build.sh, set the DESTDIR
308: environment variable before running make build. It should be
309: set to the pathname of an initially empty directory.
310: Problems: if you do not use build.sh, you might need to
311: update critical utilities without using DESTDIR since
312: nothing is executed from what is installed in DESTDIR.
313: (See critical utils, below.)
1.1 abs 314: Build often:
315: This keeps critical utilities current enough to not choke
316: on any other part of the source tree that depends on up to
1.123 jmc 317: date functionality. If you use build.sh, you should not have
318: this problem.
1.1 abs 319:
320: What to do if things don't work:
321: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
322: When things don't work there is usually a few things that commonly
323: should be done.
324: 1) make includes
325: This should be done automatically by make build.
326: 2) cd share/mk && make install
327: Again, automatically done by make build.
328:
329: Failsafe rebuild of a small part of the tree:
330: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
331: To make sure you rebuild something correctly you want to do
332: something like the following:
333: 1) Make sure the includes and .mk files are up to date.
334: 2) Make sure any program used to build the particular
335: utility is up to date. (yacc, lex, etc...)
336: 3) cd ...path/to/util...
337: make cleandir
338: rm ...all obj directories...
339: make cleandir # yes, again
340: make obj
341: make depend && make
342:
343: Failsafe rebuild of the entire tree:
344: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
345: If you really want to make sure the source tree is clean and
1.2 mrg 346: ready for a build try the following. Note that sourcing /etc/mk.conf
347: (a make(1) Makefile) in this manner is not right, and will not work
348: for anyone who uses any make(1) features in /etc/mk.conf.
