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.

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