$NetBSD: UPDATING,v 1.168 2007/12/17 14:38:40 joerg Exp $
|
|
|
|
This file (UPDATING) is intended to be a brief reference to recent
|
|
changes that might cause problems in the build process, and a guide for
|
|
what to do if something doesn't work.
|
|
|
|
For a more detailed description of the recommended way to build NetBSD
|
|
using build.sh, see the BUILDING file.
|
|
|
|
Note that much of the advice in this UPDATING file was written before
|
|
build.sh existed. Nevertheless, the advice here may be useful for
|
|
working around specific problems with build.sh.
|
|
|
|
See also: BUILDING, build.sh, Makefile.

|
Recent changes:
|
|
^^^^^^^^^^^^^^^
|
|
|
|
20071209:
|
|
The acpiec(4) driver has been split into two attachments. If you
|
|
get ACPI errors before the attachment, please update your kernel
|
|
configuration file appropiately or see GENERIC for more details.
|
|
|
|
20071115:
|
|
The it(4) driver has been renamed to itesio(4) and the old port
|
|
argument specified in the kernel configuration file is not valid
|
|
anymore. The itesio(4) driver now uses the Super I/O address port
|
|
rather than the EC address port. Please update your kernel
|
|
configuration file appropriately or see GENERIC for more details.
|
|
|
|
20071028:
|
|
The pccons(4) driver has been removed from the NetBSD/shark port.
|
|
You need to update any custom kernel configuration file you have
|
|
to remove any references to pccons (which includes removing the
|
|
now useless XSERVER option) and replace them with the correct
|
|
entries for the wscons driver. See the GENERIC configuration file
|
|
for more details.
|
|
|
|
20070913:
|
|
A latent bug in dhclient/dhcpd that caused it to be unable to
|
|
enumerate interfaces was fixed. The bug began to cause
|
|
problems after 20070911 when the kernel's SIOCGIFCONF
|
|
implementation was repaired. From 20070529 to 20070911 racoon
|
|
could not enumerate interfaces. (These are noted because
|
|
normal kernel/userspace version matching hygiene is not
|
|
sufficient to avoid this problem.) Ensure that both kernel
|
|
and userland are from after 20070913.
|
|
|
|
20070703:
|
|
nbinstall has been renamed as it calls the target specific and
|
|
the logic to pass down STRIP from mk been removed. This forces
|
|
a re-installation of tools.
|
|
|
|
20070422:
|
|
The way OS emulations lookup filenames inside the emulation root
|
|
has been changed. Rather than modify the pathname (and copy back
|
|
to userspace) namei() and lookup() directly check the emulation
|
|
root. One side effect is that absolute symlinks inside the emulated
|
|
root file system will be relative to that file system - unless they
|
|
start /../ this is useful when the emulated root is a real install
|
|
that has such links.
|
|
This might affect symlinks that have been added to reference outside
|
|
the emulated root.
|
|
|
|
20070412:
|
|
The pckbc driver on sgimips IP32 has been removed. Use macekbc
|
|
instead. See the GENERIC32_IP3x kernel configuration for an
|
|
example.
|
|
|
|
20070319:
|
|
src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
|
|
on many platforms due to incorrect flags settings. If you
|
|
updated and built after about 20070315, do "nbmake-$arch
|
|
cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
|
|
rebuild of object files that might have been built
|
|
incorrectly, and ensure that you have at least
|
|
src/lib/libc/Makefile 1.130.
|
|
|
|
20070210:
|
|
src/sys/sys/{sa.h,savar.h} were removed.
|
|
find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
|
|
| xargs egrep -l '/sa.h|/savar.h' | xargs rm
|
|
will allow dependencies on those files to get get rebuilt
|
|
|
|
20070209:
|
|
The threading model was changed when the newlock2 branch
|
|
was merged to NetBSD-current. If you boot with a new
|
|
kernel (version 4.99.10), then you also need a new pthread
|
|
library (/usr/lib/libpthread.so.0.7). If you boot with
|
|
an old kernel, then you need the old pthread library
|
|
(/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
|
|
the pthread library in sync, old threaded applications should
|
|
continue to work with an old or new kernel. Note that named(8)
|
|
is the only threaded application in the base system.
|
|
|
|
20061214:
|
|
Following the move of string_to_flags() and flags_to_string()
|
|
from the bin/ls/ sources to libutil, users doing UPDATE builds
|
|
will need to do a "make cleandir" in
|
|
tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
|
|
bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
|
|
usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
|
|
as the installation images in distrib/
|
|
in order to excise stale references to the old stat_flags.h header
|
|
file in the ls sources -- stat_flags.h has been removed.
|
|
|
|
20061108:
|
|
The configure script used in the src/tools/gcc compiler has been
|
|
changed to indicate that our libc has ssp support built-in and
|
|
does not depend on -lssp and -lssp-nonshared. You'll need to
|
|
make clean in src/tools/gcc first to rebuild the compiler.
|
|
|
|
20061009:
|
|
The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
|
|
available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
|
|
|
|
20060814:
|
|
The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
|
|
withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
|
|
kernel configuration for an example. X servers from the last
|
|
few years should cope.
|
|
|
|
20060703:
|
|
MPACPI is no more. We always configure PCI interrupts using ACPI
|
|
if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
|
|
to ACPI_SCANPCI. Thanks to work from fvdl.
|
|
|
|
20060627:
|
|
socket(2) has changed, and its system call has been versioned.
|
|
For userlands with the old version of socket(2), make sure that
|
|
your kernel has 'options COMPAT_30' set, or else 'bad system call'
|
|
errors will result.
|
|
|
|
Hints for a more successful build:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
Use build.sh, but do not use its "expert mode":
|
|
This will automatically build the tools in the
|
|
correct order, and it will keep the tools and the
|
|
new build products from interfering with the running
|
|
system. This will allow you to ignore most of the
|
|
other advice in this file.
|
|
Build a new kernel first:
|
|
This makes sure that any new system calls or features
|
|
expected by the new userland will be present. This
|
|
helps to avoid critical errors when upgrading.
|
|
Use object directories:
|
|
This helps to keep stale object
|
|
files from polluting the build if a Makefile "forgets"
|
|
about one. It also makes it easier to clean up after
|
|
a build. It's also necessary if you want to use the
|
|
same source tree for multiple machines.
|
|
To use object directories with build.sh:
|
|
a) invoke build.sh with the "-M" or "-O" options.
|
|
To use object directories without using build.sh:
|
|
a) cd /usr/src ; make cleandir
|
|
b) Add "OBJMACHINE=yes" to /etc/mk.conf
|
|
c) Add "MKOBJDIRS=yes" to /etc/mk.conf
|
|
d) cd /usr/src ; make build
|
|
Note that running "make obj" in a directory will create
|
|
in obj.$MACHINE directory.
|
|
Build to a DESTDIR:
|
|
This helps to keep old installed files (especially libraries)
|
|
from interfering with the new build.
|
|
To build to a DESTDIR with build.sh, use the "-D" option.
|
|
To build to a DESTDIR without using build.sh, set the DESTDIR
|
|
environment variable before running make build. It should be
|
|
set to the pathname of an initially empty directory.
|
|
Problems: if you do not use build.sh, you might need to
|
|
update critical utilities without using DESTDIR since
|
|
nothing is executed from what is installed in DESTDIR.
|
|
(See critical utils, below.)
|
|
Build often:
|
|
This keeps critical utilities current enough to not choke
|
|
on any other part of the source tree that depends on up to
|
|
date functionality. If you use build.sh, you should not have
|
|
this problem.
|
|
|
|
What to do if things don't work:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
When things don't work there is usually a few things that commonly
|
|
should be done.
|
|
1) make includes
|
|
This should be done automatically by make build.
|
|
2) cd share/mk && make install
|
|
Again, automatically done by make build.
|
|
|
|
Failsafe rebuild of a small part of the tree:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
To make sure you rebuild something correctly you want to do
|
|
something like the following:
|
|
1) Make sure the includes and .mk files are up to date.
|
|
2) Make sure any program used to build the particular
|
|
utility is up to date. (yacc, lex, etc...)
|
|
3) cd ...path/to/util...
|
|
make cleandir
|
|
rm ...all obj directories...
|
|
make cleandir # yes, again
|
|
make obj
|
|
make depend && make
|
|
|
|
Failsafe rebuild of the entire tree:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
If you really want to make sure the source tree is clean and
|
|
ready for a build try the following. Note that sourcing /etc/mk.conf
|
|
(a make(1) Makefile) in this manner is not right, and will not work
|
|
for anyone who uses any make(1) features in /etc/mk.conf.
|
|
|
|
---cut here---
|
|
#!/bin/sh
|
|
. /etc/mk.conf
|
|
|
|
if [ -z $NETBSDSRCDIR ] ; then
|
|
NETBSDSRCDIR=/usr/src
|
|
fi
|
|
if [ \! -d $NETBSDSRCDIR ] ; then
|
|
echo Unable to find sources
|
|
exit 1
|
|
fi
|
|
find $NETBSDSRCDIR -name \*.o -o -name obj.\* -o -name obj -exec rm \{\} \;
|
|
|
|
if [ -z $BSDOBJDIR ] ; then
|
|
BSDOBJDIR=/usr/obj
|
|
fi
|
|
if [ -d $BSDOBJDIR ] ; then
|
|
rm -rf $BSDOBJDIR
|
|
fi
|
|
|
|
cd $NETBSDSRCDIR && make cleandir
|
|
|
|
---cut here---

Critical utilities:
|
|
^^^^^^^^^^^^^^^^^^^
|
|
usr.bin/compile_et
|
|
usr.bin/make
|
|
usr.bin/yacc
|
|
usr.bin/lex
|
|
usr.bin/xlint
|
|
usr.bin/config
|
|
|
|
Other problems and possible solutions:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
Symptom:Complaints involving a Makefile.
|
|
Fix: Rebuild usr.bin/make:
|
|
cd usr.bin/make && make && make install
|
|
Or, a failsafe method if that doesn't work:
|
|
cd usr.bin/make && cc *.c */*.c -I . -o make && mv make /usr/bin
|
|
|
|
Fix: Make sure .mk files are up to date.
|
|
cd share/mk && make install
|
|
|
|
Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
|
|
Fix: Rebuild usr.bin/config
|
|
|
|
Symptom:
|
|
Fix: Rebuild usr.bin/yacc
|
|
|
|
Symptom:
|
|
Fix: Rebuild usr.bin/lex
|
|
|
|
Symptom:
|
|
Fix: rm /usr/lib/libbfd.a
|
|
|
|
Symptom:Obsolete intermediate files are used during compilation
|
|
Fix: Try the following sequence of commands in the directory in question.
|
|
make cleandir; rm `make print-objdir`; make cleandir; make obj
|
|
(If you built the tree without "make obj" in the past, obsolete files
|
|
may remain. The command tries to clean everything up)
|
|
|
|
Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible pointer type
|
|
Fix: Rebuild and install usr.bin/menuc
|
|
|
|
Symptom:mklocale not found during build in share/locale/ctype
|
|
Fix: Build and install usr.bin/mklocale
|
|
|
|
Symptom:undefined reference to `__assert13' or `__unsetenv13'
|
|
Fix: Rebuild and install lib/libc
|
|
|
|
Symptom:usr.bin/config fails to build.
|
|
Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
|
|
|
|
Symptom:undefined reference to `getprogname' or `setprogname'
|
|
Fix: Rebuild and install lib/libc
|
|
|
|
Symptom:lint does not understand the '-X' option
|
|
Fix: May need to build & install libs with NOLINT=1 before rebuilding lint
