1.190 ! apb 1: $NetBSD: UPDATING,v 1.189 2009/01/14 15:53:29 hubertf 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:
1.184 christos 19: 20090110:
20: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
21: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 22: This is needed even in the MODULAR kernel because there is
23: conditionally compiled code in rtsock.c.
1.184 christos 24: 2. make sure build.sh completes and the binaries in a chroot work
25: before installing.
26: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 27: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 28: are installed properly, and start building libraries first libc
29: and libutil, install them and then continue building all the
30: libraries in src/lib and src/gnu/lib and install them. Once
31: the new libraries are installed, you can restart the build.
32: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 33: rebuild the required packages to update their shared libraries.
34: Any package you rebuild will require rebuilding all the packages
35: that depend on it.
1.186 christos 36: 5. Next time you run pwd_mkdb with the new binary, the file
37: will be upgraded and it will not be backwards compatible.
1.190 ! apb 38: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
! 39: lastlogx(5)) have been versioned, and there is a heuristic
! 40: for utmp. You are better off removing the old files after
! 41: upgrading. The automated clearing of /var/run during
! 42: boot, and the automated rotating of files in /var/log by
! 43: newsyslog(8), may mean that you do not have to remove the
! 44: files manually.
! 45: 7. The optional accounting file (/var/account/acct, see
! 46: accton(8)) has not been versioned, and will need to be
! 47: removed. The automatic rotation of the accounting file by
! 48: /etc/daily limits the bad consequences of failure to remove
! 49: the file.
1.185 jmcneill 50:
1.183 pgoyette 51: 20081219:
52: config(1) has been updated, and one of the files it creates -
53: swapnetbsd.o - has changed format. You need to rebuild config
54: (done automatically by build.sh) and then you need to rerun
55: config on all kernel configuration files before rebuilding those
56: kernels.
57:
1.181 cube 58: 20081205:
59: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
60: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
61: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 62:
1.179 tsutsui 63: 20081122:
1.182 tsutsui 64: On i386, various kernel options(4) in GENERIC including
1.180 wiz 65: file systems have been disabled and moved into kernel modules.
66: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 67: following files as well as a new GENERIC kernel:
68:
69: - build and install kernel modules from src/sys/modules
70:
71: - install the latest bootloader, which will load a module
1.180 wiz 72: for the file system from which the kernel is loaded automatically
1.179 tsutsui 73:
1.180 wiz 74: If you have to load your kernel from a file system which is not of
75: the same type as the root file system, you have to load the necessary
76: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 77:
1.178 lukem 78: 20080827:
79: If you built and installed a libc from sources between
80: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
81: which results in false errors reported by lint(1).
82: Since this breaks the libc build itself, manual help is
1.180 wiz 83: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 84: $ (cd lib/libc && make MKLINT=no dependall install)
85:
1.177 christos 86: 20080813:
87: MKDEBUG build was broken because the .depend files did not know
88: about .go files. You need to remove all .depend files and rebuild.
89:
1.175 simonb 90: 20080731:
91: WAPBL (metadata journaling support) has been added, but at this
92: time isn't backwards compatible with pre-WAPBL aware kernels
93: and userland (fsck_ffs in particular). Please make sure you
94: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 95: especially an uncleanly mounted journaled filesystem. WAPBL
96: also requires the super block to be in the UFS2 format. You
97: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 98:
1.174 lukem 99: 20080721:
100: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
101: isn't defined.
102:
1.173 freza 103: 20080531:
104: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
105: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
106: utility needs to be rebuilt and reinstalled as older binaries
107: won't work correctly. The following sequence of commands:
108:
109: $ (cd sys/sys/ && nbmake-$arch includes)
110: $ (cd sbin/drvctl/ && nbmake-$arch clean)
111: $ (cd sbin/drvctl/ && nbmake-$arch all)
112:
113: leaves new drvctl utility in sbin/drvctl build directory.
114:
1.172 lukem 115: 20080503:
116: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
117:
1.171 he 118: 20080521:
119: For a while, unprivileged UPDATE builds would fail to
120: succeed at the checkflist stage, complaining that
121: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
122: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
123: If you already hit this problem, update the .mk file,
124: remove ${DESTDIR}/stand/<arch>, and re-run the build.
125:
1.174 lukem 126: 20080303:
127: Linker warnings are now fatal if $WARNS>0.
128:
1.170 christos 129: 20080126:
130: The posix_fadvise system call has been changed from an assembly
131: stub, to a c file that calls an assembly stub. You need to
132: 'rm -f posix_fadvise.* .depend' in the libc build directory to
133: avoid using the old assembly stub.
134:
1.168 joerg 135: 20071209:
136: The acpiec(4) driver has been split into two attachments. If you
137: get ACPI errors before the attachment, please update your kernel
1.169 wiz 138: configuration file appropriately or see GENERIC for more details.
1.168 joerg 139:
1.166 xtraeme 140: 20071115:
141: The it(4) driver has been renamed to itesio(4) and the old port
142: argument specified in the kernel configuration file is not valid
143: anymore. The itesio(4) driver now uses the Super I/O address port
144: rather than the EC address port. Please update your kernel
1.167 wiz 145: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 146:
1.165 jmmv 147: 20071028:
148: The pccons(4) driver has been removed from the NetBSD/shark port.
149: You need to update any custom kernel configuration file you have
150: to remove any references to pccons (which includes removing the
151: now useless XSERVER option) and replace them with the correct
152: entries for the wscons driver. See the GENERIC configuration file
153: for more details.
154:
1.164 gdt 155: 20070913:
156: A latent bug in dhclient/dhcpd that caused it to be unable to
157: enumerate interfaces was fixed. The bug began to cause
158: problems after 20070911 when the kernel's SIOCGIFCONF
159: implementation was repaired. From 20070529 to 20070911 racoon
160: could not enumerate interfaces. (These are noted because
161: normal kernel/userspace version matching hygiene is not
162: sufficient to avoid this problem.) Ensure that both kernel
163: and userland are from after 20070913.
164:
1.163 joerg 165: 20070703:
166: nbinstall has been renamed as it calls the target specific and
167: the logic to pass down STRIP from mk been removed. This forces
168: a re-installation of tools.
169:
1.161 dsl 170: 20070422:
171: The way OS emulations lookup filenames inside the emulation root
172: has been changed. Rather than modify the pathname (and copy back
173: to userspace) namei() and lookup() directly check the emulation
174: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 175: root file system will be relative to that file system - unless they
1.161 dsl 176: start /../ this is useful when the emulated root is a real install
177: that has such links.
178: This might affect symlinks that have been added to reference outside
179: the emulated root.
180:
1.160 jmcneill 181: 20070412:
182: The pckbc driver on sgimips IP32 has been removed. Use macekbc
183: instead. See the GENERIC32_IP3x kernel configuration for an
184: example.
185:
1.159 gdt 186: 20070319:
187: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
188: on many platforms due to incorrect flags settings. If you
189: updated and built after about 20070315, do "nbmake-$arch
190: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
191: rebuild of object files that might have been built
192: incorrectly, and ensure that you have at least
193: src/lib/libc/Makefile 1.130.
194:
1.158 dbj 195: 20070210:
196: src/sys/sys/{sa.h,savar.h} were removed.
197: find ${OBJDIR} $ -name .depend -o -name '*.d' $ -print \
198: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
199: will allow dependencies on those files to get get rebuilt
200:
1.157 apb 201: 20070209:
202: The threading model was changed when the newlock2 branch
203: was merged to NetBSD-current. If you boot with a new
204: kernel (version 4.99.10), then you also need a new pthread
205: library (/usr/lib/libpthread.so.0.7). If you boot with
206: an old kernel, then you need the old pthread library
207: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
208: the pthread library in sync, old threaded applications should
209: continue to work with an old or new kernel. Note that named(8)
210: is the only threaded application in the base system.
211:
1.154 he 212: 20061214:
213: Following the move of string_to_flags() and flags_to_string()
214: from the bin/ls/ sources to libutil, users doing UPDATE builds
215: will need to do a "make cleandir" in
216: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
217: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 218: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
219: as the installation images in distrib/
1.154 he 220: in order to excise stale references to the old stat_flags.h header
221: file in the ls sources -- stat_flags.h has been removed.
222:
1.152 christos 223: 20061108:
224: The configure script used in the src/tools/gcc compiler has been
225: changed to indicate that our libc has ssp support built-in and
226: does not depend on -lssp and -lssp-nonshared. You'll need to
227: make clean in src/tools/gcc first to rebuild the compiler.
228:
1.151 rpaulo 229: 20061009:
230: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
231: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
232:
1.150 bjh21 233: 20060814:
234: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
235: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
236: kernel configuration for an example. X servers from the last
237: few years should cope.
238:
1.149 christos 239: 20060703:
240: MPACPI is no more. We always configure PCI interrupts using ACPI
241: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
242: to ACPI_SCANPCI. Thanks to work from fvdl.
243:
1.148 dogcow 244: 20060627:
245: socket(2) has changed, and its system call has been versioned.
246: For userlands with the old version of socket(2), make sure that
247: your kernel has 'options COMPAT_30' set, or else 'bad system call'
248: errors will result.
249:
1.1 abs 250: Hints for a more successful build:
251: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 252: Use build.sh, but do not use its "expert mode":
1.132 jmmv 253: This will automatically build the tools in the
1.123 jmc 254: correct order, and it will keep the tools and the
255: new build products from interfering with the running
256: system. This will allow you to ignore most of the
257: other advice in this file.
1.2 mrg 258: Build a new kernel first:
259: This makes sure that any new system calls or features
260: expected by the new userland will be present. This
261: helps to avoid critical errors when upgrading.
1.1 abs 262: Use object directories:
263: This helps to keep stale object
264: files from polluting the build if a Makefile "forgets"
265: about one. It also makes it easier to clean up after
266: a build. It's also necessary if you want to use the
267: same source tree for multiple machines.
1.123 jmc 268: To use object directories with build.sh:
269: a) invoke build.sh with the "-M" or "-O" options.
270: To use object directories without using build.sh:
1.1 abs 271: a) cd /usr/src ; make cleandir
1.2 mrg 272: b) Add "OBJMACHINE=yes" to /etc/mk.conf
273: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 274: d) cd /usr/src ; make build
1.2 mrg 275: Note that running "make obj" in a directory will create
276: in obj.$MACHINE directory.
1.1 abs 277: Build to a DESTDIR:
1.123 jmc 278: This helps to keep old installed files (especially libraries)
279: from interfering with the new build.
280: To build to a DESTDIR with build.sh, use the "-D" option.
281: To build to a DESTDIR without using build.sh, set the DESTDIR
282: environment variable before running make build. It should be
283: set to the pathname of an initially empty directory.
284: Problems: if you do not use build.sh, you might need to
285: update critical utilities without using DESTDIR since
286: nothing is executed from what is installed in DESTDIR.
287: (See critical utils, below.)
1.1 abs 288: Build often:
289: This keeps critical utilities current enough to not choke
290: on any other part of the source tree that depends on up to
1.123 jmc 291: date functionality. If you use build.sh, you should not have
292: this problem.
1.1 abs 293:
294: What to do if things don't work:
295: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
296: When things don't work there is usually a few things that commonly
297: should be done.
298: 1) make includes
299: This should be done automatically by make build.
300: 2) cd share/mk && make install
301: Again, automatically done by make build.
302:
303: Failsafe rebuild of a small part of the tree:
304: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
305: To make sure you rebuild something correctly you want to do
306: something like the following:
307: 1) Make sure the includes and .mk files are up to date.
308: 2) Make sure any program used to build the particular
309: utility is up to date. (yacc, lex, etc...)
310: 3) cd ...path/to/util...
311: make cleandir
312: rm ...all obj directories...
313: make cleandir # yes, again
314: make obj
315: make depend && make
316:
317: Failsafe rebuild of the entire tree:
318: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
319: If you really want to make sure the source tree is clean and
1.2 mrg 320: ready for a build try the following. Note that sourcing /etc/mk.conf
321: (a make(1) Makefile) in this manner is not right, and will not work
322: for anyone who uses any make(1) features in /etc/mk.conf.
