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