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.

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