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