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.

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