1.189 ! hubertf 1: $NetBSD: UPDATING,v 1.188 2009/01/11 18:00:04 christos 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.
38: 6. The utmpx/wtmpx files have been versioned, and there is
39: a heuristic for utmp. You are better off removing the
1.188 christos 40: old files after upgrading. The accounting file has not
41: been versioned, and will need to be removed.
1.185 jmcneill 42:
1.183 pgoyette 43: 20081219:
44: config(1) has been updated, and one of the files it creates -
45: swapnetbsd.o - has changed format. You need to rebuild config
46: (done automatically by build.sh) and then you need to rerun
47: config on all kernel configuration files before rebuilding those
48: kernels.
49:
1.181 cube 50: 20081205:
51: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
52: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
53: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 54:
1.179 tsutsui 55: 20081122:
1.182 tsutsui 56: On i386, various kernel options(4) in GENERIC including
1.180 wiz 57: file systems have been disabled and moved into kernel modules.
58: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 59: following files as well as a new GENERIC kernel:
60:
61: - build and install kernel modules from src/sys/modules
62:
63: - install the latest bootloader, which will load a module
1.180 wiz 64: for the file system from which the kernel is loaded automatically
1.179 tsutsui 65:
1.180 wiz 66: If you have to load your kernel from a file system which is not of
67: the same type as the root file system, you have to load the necessary
68: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 69:
1.178 lukem 70: 20080827:
71: If you built and installed a libc from sources between
72: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
73: which results in false errors reported by lint(1).
74: Since this breaks the libc build itself, manual help is
1.180 wiz 75: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 76: $ (cd lib/libc && make MKLINT=no dependall install)
77:
1.177 christos 78: 20080813:
79: MKDEBUG build was broken because the .depend files did not know
80: about .go files. You need to remove all .depend files and rebuild.
81:
1.175 simonb 82: 20080731:
83: WAPBL (metadata journaling support) has been added, but at this
84: time isn't backwards compatible with pre-WAPBL aware kernels
85: and userland (fsck_ffs in particular). Please make sure you
86: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 87: especially an uncleanly mounted journaled filesystem. WAPBL
88: also requires the super block to be in the UFS2 format. You
89: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 90:
1.174 lukem 91: 20080721:
92: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
93: isn't defined.
94:
1.173 freza 95: 20080531:
96: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
97: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
98: utility needs to be rebuilt and reinstalled as older binaries
99: won't work correctly. The following sequence of commands:
100:
101: $ (cd sys/sys/ && nbmake-$arch includes)
102: $ (cd sbin/drvctl/ && nbmake-$arch clean)
103: $ (cd sbin/drvctl/ && nbmake-$arch all)
104:
105: leaves new drvctl utility in sbin/drvctl build directory.
106:
1.172 lukem 107: 20080503:
108: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
109:
1.171 he 110: 20080521:
111: For a while, unprivileged UPDATE builds would fail to
112: succeed at the checkflist stage, complaining that
113: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
114: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
115: If you already hit this problem, update the .mk file,
116: remove ${DESTDIR}/stand/<arch>, and re-run the build.
117:
1.174 lukem 118: 20080303:
119: Linker warnings are now fatal if $WARNS>0.
120:
1.170 christos 121: 20080126:
122: The posix_fadvise system call has been changed from an assembly
123: stub, to a c file that calls an assembly stub. You need to
124: 'rm -f posix_fadvise.* .depend' in the libc build directory to
125: avoid using the old assembly stub.
126:
1.168 joerg 127: 20071209:
128: The acpiec(4) driver has been split into two attachments. If you
129: get ACPI errors before the attachment, please update your kernel
1.169 wiz 130: configuration file appropriately or see GENERIC for more details.
1.168 joerg 131:
1.166 xtraeme 132: 20071115:
133: The it(4) driver has been renamed to itesio(4) and the old port
134: argument specified in the kernel configuration file is not valid
135: anymore. The itesio(4) driver now uses the Super I/O address port
136: rather than the EC address port. Please update your kernel
1.167 wiz 137: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 138:
1.165 jmmv 139: 20071028:
140: The pccons(4) driver has been removed from the NetBSD/shark port.
141: You need to update any custom kernel configuration file you have
142: to remove any references to pccons (which includes removing the
143: now useless XSERVER option) and replace them with the correct
144: entries for the wscons driver. See the GENERIC configuration file
145: for more details.
146:
1.164 gdt 147: 20070913:
148: A latent bug in dhclient/dhcpd that caused it to be unable to
149: enumerate interfaces was fixed. The bug began to cause
150: problems after 20070911 when the kernel's SIOCGIFCONF
151: implementation was repaired. From 20070529 to 20070911 racoon
152: could not enumerate interfaces. (These are noted because
153: normal kernel/userspace version matching hygiene is not
154: sufficient to avoid this problem.) Ensure that both kernel
155: and userland are from after 20070913.
156:
1.163 joerg 157: 20070703:
158: nbinstall has been renamed as it calls the target specific and
159: the logic to pass down STRIP from mk been removed. This forces
160: a re-installation of tools.
161:
1.161 dsl 162: 20070422:
163: The way OS emulations lookup filenames inside the emulation root
164: has been changed. Rather than modify the pathname (and copy back
165: to userspace) namei() and lookup() directly check the emulation
166: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 167: root file system will be relative to that file system - unless they
1.161 dsl 168: start /../ this is useful when the emulated root is a real install
169: that has such links.
170: This might affect symlinks that have been added to reference outside
171: the emulated root.
172:
1.160 jmcneill 173: 20070412:
174: The pckbc driver on sgimips IP32 has been removed. Use macekbc
175: instead. See the GENERIC32_IP3x kernel configuration for an
176: example.
177:
1.159 gdt 178: 20070319:
179: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
180: on many platforms due to incorrect flags settings. If you
181: updated and built after about 20070315, do "nbmake-$arch
182: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
183: rebuild of object files that might have been built
184: incorrectly, and ensure that you have at least
185: src/lib/libc/Makefile 1.130.
186:
1.158 dbj 187: 20070210:
188: src/sys/sys/{sa.h,savar.h} were removed.
189: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
190: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
191: will allow dependencies on those files to get get rebuilt
192:
1.157 apb 193: 20070209:
194: The threading model was changed when the newlock2 branch
195: was merged to NetBSD-current. If you boot with a new
196: kernel (version 4.99.10), then you also need a new pthread
197: library (/usr/lib/libpthread.so.0.7). If you boot with
198: an old kernel, then you need the old pthread library
199: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
200: the pthread library in sync, old threaded applications should
201: continue to work with an old or new kernel. Note that named(8)
202: is the only threaded application in the base system.
203:
1.154 he 204: 20061214:
205: Following the move of string_to_flags() and flags_to_string()
206: from the bin/ls/ sources to libutil, users doing UPDATE builds
207: will need to do a "make cleandir" in
208: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
209: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 210: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
211: as the installation images in distrib/
1.154 he 212: in order to excise stale references to the old stat_flags.h header
213: file in the ls sources -- stat_flags.h has been removed.
214:
1.152 christos 215: 20061108:
216: The configure script used in the src/tools/gcc compiler has been
217: changed to indicate that our libc has ssp support built-in and
218: does not depend on -lssp and -lssp-nonshared. You'll need to
219: make clean in src/tools/gcc first to rebuild the compiler.
220:
1.151 rpaulo 221: 20061009:
222: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
223: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
224:
1.150 bjh21 225: 20060814:
226: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
227: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
228: kernel configuration for an example. X servers from the last
229: few years should cope.
230:
1.149 christos 231: 20060703:
232: MPACPI is no more. We always configure PCI interrupts using ACPI
233: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
234: to ACPI_SCANPCI. Thanks to work from fvdl.
235:
1.148 dogcow 236: 20060627:
237: socket(2) has changed, and its system call has been versioned.
238: For userlands with the old version of socket(2), make sure that
239: your kernel has 'options COMPAT_30' set, or else 'bad system call'
240: errors will result.
241:
1.1 abs 242: Hints for a more successful build:
243: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 244: Use build.sh, but do not use its "expert mode":
1.132 jmmv 245: This will automatically build the tools in the
1.123 jmc 246: correct order, and it will keep the tools and the
247: new build products from interfering with the running
248: system. This will allow you to ignore most of the
249: other advice in this file.
1.2 mrg 250: Build a new kernel first:
251: This makes sure that any new system calls or features
252: expected by the new userland will be present. This
253: helps to avoid critical errors when upgrading.
1.1 abs 254: Use object directories:
255: This helps to keep stale object
256: files from polluting the build if a Makefile "forgets"
257: about one. It also makes it easier to clean up after
258: a build. It's also necessary if you want to use the
259: same source tree for multiple machines.
1.123 jmc 260: To use object directories with build.sh:
261: a) invoke build.sh with the "-M" or "-O" options.
262: To use object directories without using build.sh:
1.1 abs 263: a) cd /usr/src ; make cleandir
1.2 mrg 264: b) Add "OBJMACHINE=yes" to /etc/mk.conf
265: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 266: d) cd /usr/src ; make build
1.2 mrg 267: Note that running "make obj" in a directory will create
268: in obj.$MACHINE directory.
1.1 abs 269: Build to a DESTDIR:
1.123 jmc 270: This helps to keep old installed files (especially libraries)
271: from interfering with the new build.
272: To build to a DESTDIR with build.sh, use the "-D" option.
273: To build to a DESTDIR without using build.sh, set the DESTDIR
274: environment variable before running make build. It should be
275: set to the pathname of an initially empty directory.
276: Problems: if you do not use build.sh, you might need to
277: update critical utilities without using DESTDIR since
278: nothing is executed from what is installed in DESTDIR.
279: (See critical utils, below.)
1.1 abs 280: Build often:
281: This keeps critical utilities current enough to not choke
282: on any other part of the source tree that depends on up to
1.123 jmc 283: date functionality. If you use build.sh, you should not have
284: this problem.
1.1 abs 285:
286: What to do if things don't work:
287: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
288: When things don't work there is usually a few things that commonly
289: should be done.
290: 1) make includes
291: This should be done automatically by make build.
292: 2) cd share/mk && make install
293: Again, automatically done by make build.
294:
295: Failsafe rebuild of a small part of the tree:
296: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
297: To make sure you rebuild something correctly you want to do
298: something like the following:
299: 1) Make sure the includes and .mk files are up to date.
300: 2) Make sure any program used to build the particular
301: utility is up to date. (yacc, lex, etc...)
302: 3) cd ...path/to/util...
303: make cleandir
304: rm ...all obj directories...
305: make cleandir # yes, again
306: make obj
307: make depend && make
308:
309: Failsafe rebuild of the entire tree:
310: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
311: If you really want to make sure the source tree is clean and
1.2 mrg 312: ready for a build try the following. Note that sourcing /etc/mk.conf
313: (a make(1) Makefile) in this manner is not right, and will not work
314: for anyone who uses any make(1) features in /etc/mk.conf.
