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.

14: See also: BUILDING, build.sh, Makefile.

16: Recent changes:
17: ^^^^^^^^^^^^^^^
1.138 lukem 18:
1.177 ! christos 19: 20080813:
! 20: MKDEBUG build was broken because the .depend files did not know
! 21: about .go files. You need to remove all .depend files and rebuild.
! 22:
1.175 simonb 23: 20080731:
24: WAPBL (metadata journaling support) has been added, but at this
25: time isn't backwards compatible with pre-WAPBL aware kernels
26: and userland (fsck_ffs in particular). Please make sure you
27: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 28: especially an uncleanly mounted journaled filesystem. WAPBL
29: also requires the super block to be in the UFS2 format. You
30: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 31:
1.174 lukem 32: 20080721:
33: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
34: isn't defined.
35:
1.173 freza 36: 20080531:
37: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
38: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
39: utility needs to be rebuilt and reinstalled as older binaries
40: won't work correctly. The following sequence of commands:
41:
42: $ (cd sys/sys/ && nbmake-$arch includes)
43: $ (cd sbin/drvctl/ && nbmake-$arch clean)
44: $ (cd sbin/drvctl/ && nbmake-$arch all)
45:
46: leaves new drvctl utility in sbin/drvctl build directory.
47:
1.172 lukem 48: 20080503:
49: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
50:
1.171 he 51: 20080521:
52: For a while, unprivileged UPDATE builds would fail to
53: succeed at the checkflist stage, complaining that
54: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
55: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
56: If you already hit this problem, update the .mk file,
57: remove ${DESTDIR}/stand/<arch>, and re-run the build.
58:
1.174 lukem 59: 20080303:
60: Linker warnings are now fatal if $WARNS>0.
61:
1.170 christos 62: 20080126:
63: The posix_fadvise system call has been changed from an assembly
64: stub, to a c file that calls an assembly stub. You need to
65: 'rm -f posix_fadvise.* .depend' in the libc build directory to
66: avoid using the old assembly stub.
67:
1.168 joerg 68: 20071209:
69: The acpiec(4) driver has been split into two attachments. If you
70: get ACPI errors before the attachment, please update your kernel
1.169 wiz 71: configuration file appropriately or see GENERIC for more details.
1.168 joerg 72:
1.166 xtraeme 73: 20071115:
74: The it(4) driver has been renamed to itesio(4) and the old port
75: argument specified in the kernel configuration file is not valid
76: anymore. The itesio(4) driver now uses the Super I/O address port
77: rather than the EC address port. Please update your kernel
1.167 wiz 78: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 79:
1.165 jmmv 80: 20071028:
81: The pccons(4) driver has been removed from the NetBSD/shark port.
82: You need to update any custom kernel configuration file you have
83: to remove any references to pccons (which includes removing the
84: now useless XSERVER option) and replace them with the correct
85: entries for the wscons driver. See the GENERIC configuration file
86: for more details.
87:
1.164 gdt 88: 20070913:
89: A latent bug in dhclient/dhcpd that caused it to be unable to
90: enumerate interfaces was fixed. The bug began to cause
91: problems after 20070911 when the kernel's SIOCGIFCONF
92: implementation was repaired. From 20070529 to 20070911 racoon
93: could not enumerate interfaces. (These are noted because
94: normal kernel/userspace version matching hygiene is not
95: sufficient to avoid this problem.) Ensure that both kernel
96: and userland are from after 20070913.
97:
1.163 joerg 98: 20070703:
99: nbinstall has been renamed as it calls the target specific and
100: the logic to pass down STRIP from mk been removed. This forces
101: a re-installation of tools.
102:
1.161 dsl 103: 20070422:
104: The way OS emulations lookup filenames inside the emulation root
105: has been changed. Rather than modify the pathname (and copy back
106: to userspace) namei() and lookup() directly check the emulation
107: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 108: root file system will be relative to that file system - unless they
1.161 dsl 109: start /../ this is useful when the emulated root is a real install
110: that has such links.
111: This might affect symlinks that have been added to reference outside
112: the emulated root.
113:
1.160 jmcneill 114: 20070412:
115: The pckbc driver on sgimips IP32 has been removed. Use macekbc
116: instead. See the GENERIC32_IP3x kernel configuration for an
117: example.
118:
1.159 gdt 119: 20070319:
120: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
121: on many platforms due to incorrect flags settings. If you
122: updated and built after about 20070315, do "nbmake-$arch
123: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
124: rebuild of object files that might have been built
125: incorrectly, and ensure that you have at least
126: src/lib/libc/Makefile 1.130.
127:
1.158 dbj 128: 20070210:
129: src/sys/sys/{sa.h,savar.h} were removed.
130: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
131: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
132: will allow dependencies on those files to get get rebuilt
133:
1.157 apb 134: 20070209:
135: The threading model was changed when the newlock2 branch
136: was merged to NetBSD-current. If you boot with a new
137: kernel (version 4.99.10), then you also need a new pthread
138: library (/usr/lib/libpthread.so.0.7). If you boot with
139: an old kernel, then you need the old pthread library
140: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
141: the pthread library in sync, old threaded applications should
142: continue to work with an old or new kernel. Note that named(8)
143: is the only threaded application in the base system.
144:
1.154 he 145: 20061214:
146: Following the move of string_to_flags() and flags_to_string()
147: from the bin/ls/ sources to libutil, users doing UPDATE builds
148: will need to do a "make cleandir" in
149: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
150: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 151: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
152: as the installation images in distrib/
1.154 he 153: in order to excise stale references to the old stat_flags.h header
154: file in the ls sources -- stat_flags.h has been removed.
155:
1.152 christos 156: 20061108:
157: The configure script used in the src/tools/gcc compiler has been
158: changed to indicate that our libc has ssp support built-in and
159: does not depend on -lssp and -lssp-nonshared. You'll need to
160: make clean in src/tools/gcc first to rebuild the compiler.
161:
1.151 rpaulo 162: 20061009:
163: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
164: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
165:
1.150 bjh21 166: 20060814:
167: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
168: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
169: kernel configuration for an example. X servers from the last
170: few years should cope.
171:
1.149 christos 172: 20060703:
173: MPACPI is no more. We always configure PCI interrupts using ACPI
174: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
175: to ACPI_SCANPCI. Thanks to work from fvdl.
176:
1.148 dogcow 177: 20060627:
178: socket(2) has changed, and its system call has been versioned.
179: For userlands with the old version of socket(2), make sure that
180: your kernel has 'options COMPAT_30' set, or else 'bad system call'
181: errors will result.
182:
1.1 abs 183: Hints for a more successful build:
184: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 185: Use build.sh, but do not use its "expert mode":
1.132 jmmv 186: This will automatically build the tools in the
1.123 jmc 187: correct order, and it will keep the tools and the
188: new build products from interfering with the running
189: system. This will allow you to ignore most of the
190: other advice in this file.
1.2 mrg 191: Build a new kernel first:
192: This makes sure that any new system calls or features
193: expected by the new userland will be present. This
194: helps to avoid critical errors when upgrading.
1.1 abs 195: Use object directories:
196: This helps to keep stale object
197: files from polluting the build if a Makefile "forgets"
198: about one. It also makes it easier to clean up after
199: a build. It's also necessary if you want to use the
200: same source tree for multiple machines.
1.123 jmc 201: To use object directories with build.sh:
202: a) invoke build.sh with the "-M" or "-O" options.
203: To use object directories without using build.sh:
1.1 abs 204: a) cd /usr/src ; make cleandir
1.2 mrg 205: b) Add "OBJMACHINE=yes" to /etc/mk.conf
206: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 207: d) cd /usr/src ; make build
1.2 mrg 208: Note that running "make obj" in a directory will create
209: in obj.$MACHINE directory.
1.1 abs 210: Build to a DESTDIR:
1.123 jmc 211: This helps to keep old installed files (especially libraries)
212: from interfering with the new build.
213: To build to a DESTDIR with build.sh, use the "-D" option.
214: To build to a DESTDIR without using build.sh, set the DESTDIR
215: environment variable before running make build. It should be
216: set to the pathname of an initially empty directory.
217: Problems: if you do not use build.sh, you might need to
218: update critical utilities without using DESTDIR since
219: nothing is executed from what is installed in DESTDIR.
220: (See critical utils, below.)
1.1 abs 221: Build often:
222: This keeps critical utilities current enough to not choke
223: on any other part of the source tree that depends on up to
1.123 jmc 224: date functionality. If you use build.sh, you should not have
225: this problem.
1.1 abs 226:
227: What to do if things don't work:
228: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
229: When things don't work there is usually a few things that commonly
230: should be done.
231: 1) make includes
232: This should be done automatically by make build.
233: 2) cd share/mk && make install
234: Again, automatically done by make build.
235:
236: Failsafe rebuild of a small part of the tree:
237: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
238: To make sure you rebuild something correctly you want to do
239: something like the following:
240: 1) Make sure the includes and .mk files are up to date.
241: 2) Make sure any program used to build the particular
242: utility is up to date. (yacc, lex, etc...)
243: 3) cd ...path/to/util...
244: make cleandir
245: rm ...all obj directories...
246: make cleandir # yes, again
247: make obj
248: make depend && make
249:
250: Failsafe rebuild of the entire tree:
251: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
252: If you really want to make sure the source tree is clean and
1.2 mrg 253: ready for a build try the following. Note that sourcing /etc/mk.conf
254: (a make(1) Makefile) in this manner is not right, and will not work
255: for anyone who uses any make(1) features in /etc/mk.conf.
