1.178.2.1.2.1 2.2(matt 1:-11): $NetBSD$
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.

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.

1.138 lukem 18:
1.178.2.1.2.1 2.2(matt 19:-11): 20090616:
20:-11): Native Xorg was upgraded. Builds will need a clean objdir for
21:-11): src/external/mit/xorg. Upgrading a system from sets will not
22:-11): work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
23:-11): subdirectory has been changed into a file, and this needs to
24:-11): be manually "rm -r"'ed before installing xbase.tgz.
25:-11):
(snj 26:: 20090530:
27:: pkg_install now depends on the pkgdb cache for automatic conflict
28:: detection. It is recommented to rebuild the cache with
29:: ``pkg_admin rebuild''.
30::
31:: audit-packages.conf(5) has been superseded by pkg_install.conf(5).
32:: The default configuration is the same. Support for pkg_view(1) has
33:: been retired. The functionality of audit-packages(1) and
34:: download-vulnerability-list(1) has moved into pkg_admin(1), wrapper
35:: scripts that handle the common use cases are provided.
36::
1.178.2.1 snj 37: 20081205:
38: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
39: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
40: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 41:
42: 20080827:
43: If you built and installed a libc from sources between
44: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
45: which results in false errors reported by lint(1).
46: Since this breaks the libc build itself, manual help is
47: needed -- lint must be disabled temporarily, e.g:
48: $ (cd lib/libc && make MKLINT=no dependall install)
49:
1.177 christos 50: 20080813:
51: MKDEBUG build was broken because the .depend files did not know
52: about .go files. You need to remove all .depend files and rebuild.
53:
1.175 simonb 54: 20080731:
55: WAPBL (metadata journaling support) has been added, but at this
56: time isn't backwards compatible with pre-WAPBL aware kernels
57: and userland (fsck_ffs in particular). Please make sure you
58: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 59: especially an uncleanly mounted journaled filesystem. WAPBL
60: also requires the super block to be in the UFS2 format. You
61: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 62:
1.174 lukem 63: 20080721:
64: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
65: isn't defined.
66:
1.173 freza 67: 20080531:
68: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
69: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
70: utility needs to be rebuilt and reinstalled as older binaries
71: won't work correctly. The following sequence of commands:
72:
73: $ (cd sys/sys/ && nbmake-$arch includes)
74: $ (cd sbin/drvctl/ && nbmake-$arch clean)
75: $ (cd sbin/drvctl/ && nbmake-$arch all)
76:
77: leaves new drvctl utility in sbin/drvctl build directory.
78:
1.172 lukem 79: 20080503:
80: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
81:
1.171 he 82: 20080521:
83: For a while, unprivileged UPDATE builds would fail to
84: succeed at the checkflist stage, complaining that
85: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
86: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
87: If you already hit this problem, update the .mk file,
88: remove ${DESTDIR}/stand/<arch>, and re-run the build.
89:
1.174 lukem 90: 20080303:
91: Linker warnings are now fatal if $WARNS>0.
92:
1.170 christos 93: 20080126:
94: The posix_fadvise system call has been changed from an assembly
95: stub, to a c file that calls an assembly stub. You need to
96: 'rm -f posix_fadvise.* .depend' in the libc build directory to
97: avoid using the old assembly stub.
98:
1.168 joerg 99: 20071209:
100: The acpiec(4) driver has been split into two attachments. If you
101: get ACPI errors before the attachment, please update your kernel
1.169 wiz 102: configuration file appropriately or see GENERIC for more details.
1.168 joerg 103:
1.166 xtraeme 104: 20071115:
105: The it(4) driver has been renamed to itesio(4) and the old port
106: argument specified in the kernel configuration file is not valid
107: anymore. The itesio(4) driver now uses the Super I/O address port
108: rather than the EC address port. Please update your kernel
1.167 wiz 109: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 110:
1.165 jmmv 111: 20071028:
112: The pccons(4) driver has been removed from the NetBSD/shark port.
113: You need to update any custom kernel configuration file you have
114: to remove any references to pccons (which includes removing the
115: now useless XSERVER option) and replace them with the correct
116: entries for the wscons driver. See the GENERIC configuration file
117: for more details.
118:
1.164 gdt 119: 20070913:
120: A latent bug in dhclient/dhcpd that caused it to be unable to
121: enumerate interfaces was fixed. The bug began to cause
122: problems after 20070911 when the kernel's SIOCGIFCONF
123: implementation was repaired. From 20070529 to 20070911 racoon
124: could not enumerate interfaces. (These are noted because
125: normal kernel/userspace version matching hygiene is not
126: sufficient to avoid this problem.) Ensure that both kernel
127: and userland are from after 20070913.
128:
1.163 joerg 129: 20070703:
130: nbinstall has been renamed as it calls the target specific and
131: the logic to pass down STRIP from mk been removed. This forces
132: a re-installation of tools.
133:
1.161 dsl 134: 20070422:
135: The way OS emulations lookup filenames inside the emulation root
136: has been changed. Rather than modify the pathname (and copy back
137: to userspace) namei() and lookup() directly check the emulation
138: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 139: root file system will be relative to that file system - unless they
1.161 dsl 140: start /../ this is useful when the emulated root is a real install
141: that has such links.
142: This might affect symlinks that have been added to reference outside
143: the emulated root.
144:
1.160 jmcneill 145: 20070412:
146: The pckbc driver on sgimips IP32 has been removed. Use macekbc
147: instead. See the GENERIC32_IP3x kernel configuration for an
148: example.
149:
1.159 gdt 150: 20070319:
151: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
152: on many platforms due to incorrect flags settings. If you
153: updated and built after about 20070315, do "nbmake-$arch
154: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
155: rebuild of object files that might have been built
156: incorrectly, and ensure that you have at least
157: src/lib/libc/Makefile 1.130.
158:
1.158 dbj 159: 20070210:
160: src/sys/sys/{sa.h,savar.h} were removed.
161: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
162: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
163: will allow dependencies on those files to get get rebuilt
164:
1.157 apb 165: 20070209:
166: The threading model was changed when the newlock2 branch
167: was merged to NetBSD-current. If you boot with a new
168: kernel (version 4.99.10), then you also need a new pthread
169: library (/usr/lib/libpthread.so.0.7). If you boot with
170: an old kernel, then you need the old pthread library
171: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
172: the pthread library in sync, old threaded applications should
173: continue to work with an old or new kernel. Note that named(8)
174: is the only threaded application in the base system.
175:
1.154 he 176: 20061214:
177: Following the move of string_to_flags() and flags_to_string()
178: from the bin/ls/ sources to libutil, users doing UPDATE builds
179: will need to do a "make cleandir" in
180: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
181: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 182: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
183: as the installation images in distrib/
1.154 he 184: in order to excise stale references to the old stat_flags.h header
185: file in the ls sources -- stat_flags.h has been removed.
186:
1.152 christos 187: 20061108:
188: The configure script used in the src/tools/gcc compiler has been
189: changed to indicate that our libc has ssp support built-in and
190: does not depend on -lssp and -lssp-nonshared. You'll need to
191: make clean in src/tools/gcc first to rebuild the compiler.
192:
1.151 rpaulo 193: 20061009:
194: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
195: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
196:
1.150 bjh21 197: 20060814:
198: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
199: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
200: kernel configuration for an example. X servers from the last
201: few years should cope.
202:
1.149 christos 203: 20060703:
204: MPACPI is no more. We always configure PCI interrupts using ACPI
205: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
206: to ACPI_SCANPCI. Thanks to work from fvdl.
207:
1.148 dogcow 208: 20060627:
209: socket(2) has changed, and its system call has been versioned.
210: For userlands with the old version of socket(2), make sure that
211: your kernel has 'options COMPAT_30' set, or else 'bad system call'
212: errors will result.
213:
1.1 abs 214: Hints for a more successful build:
215: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 216: Use build.sh, but do not use its "expert mode":
1.132 jmmv 217: This will automatically build the tools in the
1.123 jmc 218: correct order, and it will keep the tools and the
219: new build products from interfering with the running
220: system. This will allow you to ignore most of the
221: other advice in this file.
1.2 mrg 222: Build a new kernel first:
223: This makes sure that any new system calls or features
224: expected by the new userland will be present. This
225: helps to avoid critical errors when upgrading.
1.1 abs 226: Use object directories:
227: This helps to keep stale object
228: files from polluting the build if a Makefile "forgets"
229: about one. It also makes it easier to clean up after
230: a build. It's also necessary if you want to use the
231: same source tree for multiple machines.
1.123 jmc 232: To use object directories with build.sh:
233: a) invoke build.sh with the "-M" or "-O" options.
234: To use object directories without using build.sh:
1.1 abs 235: a) cd /usr/src ; make cleandir
1.2 mrg 236: b) Add "OBJMACHINE=yes" to /etc/mk.conf
237: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 238: d) cd /usr/src ; make build
1.2 mrg 239: Note that running "make obj" in a directory will create
240: in obj.$MACHINE directory.
1.1 abs 241: Build to a DESTDIR:
1.123 jmc 242: This helps to keep old installed files (especially libraries)
243: from interfering with the new build.
244: To build to a DESTDIR with build.sh, use the "-D" option.
245: To build to a DESTDIR without using build.sh, set the DESTDIR
246: environment variable before running make build. It should be
247: set to the pathname of an initially empty directory.
248: Problems: if you do not use build.sh, you might need to
249: update critical utilities without using DESTDIR since
250: nothing is executed from what is installed in DESTDIR.
251: (See critical utils, below.)
1.1 abs 252: Build often:
253: This keeps critical utilities current enough to not choke
254: on any other part of the source tree that depends on up to
1.123 jmc 255: date functionality. If you use build.sh, you should not have
256: this problem.
1.1 abs 257:
258: What to do if things don't work:
259: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
260: When things don't work there is usually a few things that commonly
261: should be done.
262: 1) make includes
263: This should be done automatically by make build.
264: 2) cd share/mk && make install
265: Again, automatically done by make build.
266:
267: Failsafe rebuild of a small part of the tree:
268: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
269: To make sure you rebuild something correctly you want to do
270: something like the following:
271: 1) Make sure the includes and .mk files are up to date.
272: 2) Make sure any program used to build the particular
273: utility is up to date. (yacc, lex, etc...)
274: 3) cd ...path/to/util...
275: make cleandir
276: rm ...all obj directories...
277: make cleandir # yes, again
278: make obj
279: make depend && make
280:
281: Failsafe rebuild of the entire tree:
282: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
283: If you really want to make sure the source tree is clean and
1.2 mrg 284: ready for a build try the following. Note that sourcing /etc/mk.conf
285: (a make(1) Makefile) in this manner is not right, and will not work
286: for anyone who uses any make(1) features in /etc/mk.conf.
