$NetBSD: UPDATING,v 1.240 2012/09/17 05:56:27 dholland 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:
|
|
^^^^^^^^^^^^^^^
|
|
|
|
20120726:
|
|
The update of openssl requires cleaning both the openssl build
|
|
directory and DESTDIR. *Even non-update builds require cleaning
|
|
DESTDIR.* Builds done without taking these steps may fail, or in
|
|
some cases may succeed and install broken openssl libraries that
|
|
cause third-party software to link incorrectly and/or crash.
|
|
|
|
20120507:
|
|
The database schema for makemandb was changed. You will
|
|
need to update the database using 'makemandb -f' or wait
|
|
for the next weekly run to fix it.
|
|
|
|
20120319:
|
|
sys/conf/Makefile.kern.inc has been modified to adjust the
|
|
size of db_symtab automatically. You need to update dbsym in
|
|
your $TOOLDIR to build kernels with options SYMTAB_SPACE. If
|
|
you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your
|
|
mk.conf.
|
|
|
|
20120216:
|
|
Default for MKCATPAGES changed to NO. Update builds will fail
|
|
unless DESTDIR is cleaned manually. If you built between 20120207
|
|
and 20120216, daily and weekly could have created an unreadable
|
|
/var/db/man.db index for apropos. Running makemandb -f or
|
|
the next run of weekly will fix it.
|
|
|
|
20111227:
|
|
If you built between 20111225 and 20111227 you need to remove
|
|
/usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the
|
|
bump has been reverted.
|
|
|
|
20111125:
|
|
The "rnd" pseudodevice has been added to sys/conf/std, which
|
|
means it should no longer be explicitly listed in kernel
|
|
configuration files. The line "pseudo-device rnd" should be
|
|
removed from any custom kernel config files users may have.
|
|
|
|
20111119:
|
|
A problem with the datastructures used by the rndctl(8)
|
|
utility (pointers in datastructures in an array, making 32->64
|
|
bit compatibility very painful) has been fixed in a
|
|
non-backwards-compatible way. If you replace your kernel,
|
|
replace your rndctl executable too.
|
|
|
|
20111001:
|
|
the prop_*_send_syscall() functions from proplib(3) have been
|
|
changed and their new version is not backward compatible with the old
|
|
one. So ensure that all consumers of these functions (currently:
|
|
quota2 code and its tests) are updated together with the new lib.
|
|
|
|
20110817:
|
|
sparc has been changed to use GCC 4.5.3, so any objdir or
|
|
DESTDIR for them should be deleted before updating.
|
|
|
|
20110806:
|
|
i386 and amd64 have been changed to use GCC 4.5.3, so any
|
|
objdir or DESTDIR for them should be deleted before updating.
|
|
|
|
20110805:
|
|
The update to GCC 4.5.3 requires a non-trivial portion of
|
|
the tree to be cleaned. Best to delete both objdir and
|
|
DESTDIR before running this update. So far, only the
|
|
sparc64, mips and powerpc platforms have changed.
|
|
|
|
20110803:
|
|
The layout of external/public-domain/xz has changed. To do an
|
|
update build you will have to remove the contents of the OBJDIR
|
|
for external/public-domain/xz/bin by hand as the xz entry there
|
|
is now a directory.
|
|
|
|
20110410:
|
|
The configuration of src/tools/gcc has changed. To do an
|
|
update build you have to clean both tools/binutils and
|
|
tools/gcc by hand.
|
|
|
|
20110328:
|
|
Building the Xorg binary was moved into a subdirectory to fix
|
|
ordering issues with "make all". It may be necessary to remove
|
|
the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86
|
|
if your update build fails, as the "Xorg" entry there is now a
|
|
directory.
|
|
|
|
20110121:
|
|
Assembler files no longer use -traditional-cpp. This can break
|
|
the build of individual parts of the tree. This is handled
|
|
correctly by build.sh. Manual builds have to update /usr/share/mk
|
|
and re-run config(1) for any kernel configurations as needed.
|
|
|
|
20101217:
|
|
The tcpdump(8) program was changed to drop privileges and chroot(2)
|
|
by default. It may be necessary to manually update passwd(5) and
|
|
group(5) in order to make the program work with existing setups.
|
|
|
|
20101125:
|
|
The latest changes to setenv(3) dissallow setting environment
|
|
variables with names that contain '='. Revision 1.18 of env.c
|
|
assumed that this was allowed. Installing a new libc with an
|
|
old copy of /usr/bin/env causes env x=1 printenv | grep x= to
|
|
break which affects the autoconf tests for dependency finding,
|
|
so building gcc will end up printing:
|
|
checking dependency style of gcc... none
|
|
configure: error: no usable dependency style found
|
|
Fix it by rebuilding and re-installing env.
|
|
|
|
20101119:
|
|
Recent Xorg updates in xsrc/external/mit/ may cause various build
|
|
or run-time problems. Delete your entire DESTDIR and OBJDIR if you
|
|
have any build problems with xsrc, or problems with mismatched
|
|
versions between xorg-server and drivers.
|
|
|
|
20100604:
|
|
The update of ATF to 0.9 causes old tests written in shell to fail
|
|
unless they are rebuilt. If you are building with MKUPDATE=yes,
|
|
you need to clean the src/external/bsd/atf/tests/ and the src/tests/
|
|
trees by hand.
|
|
|
|
20100522:
|
|
Recent Xorg updates in xsrc/external/mit/ will cause various build
|
|
problems. Delete your entire DESTDIR and OBJDIR if you have any
|
|
build problems with xsrc.
|
|
|
|
20100522:
|
|
private section of <ctype.h> was splitted, and now mklocale(1)
|
|
include ctype_local.h, so you have to make cleandir in tools/mklocale.
|
|
|
|
20100520:
|
|
The location of the xkb compiled descriptions has changed. Please
|
|
remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
|
|
|
|
20100222:
|
|
The shared objects file extension has been changed from .so to
|
|
.pico, in order to avoid conflicts with shared libraries names
|
|
libXX.so. All now stale regular .so files can be removed from
|
|
your object directories.
|
|
|
|
20100204:
|
|
The termcap database has been removed from the sources,
|
|
but has not been marked obsolete so it is not removed
|
|
from the system when upgrading.
|
|
As such, you will need to remove them from your object
|
|
and destination directories.
|
|
|
|
20091101:
|
|
After updating, it may be necessary to make the 'cleandir'
|
|
target in src/tools/yacc/ and in src/usr.bin/yacc/ before a
|
|
'build.sh -u tools' or 'build.sh -u distribution'. Ditto
|
|
src/tools/lex/ and src/usr.bin/lex/.
|
|
|
|
20091001:
|
|
On amd64 you must rebuild tools (to get the new binutils)
|
|
before building a kernel, or the build fails on cpufunc.S.
|
|
|
|
20091001:
|
|
An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb
|
|
symlink, failing the build. Delete the link, and the subdir
|
|
it is in, and retry your build.
|
|
|
|
20090718:
|
|
libc build changed so that strchr() provides the extra entry
|
|
point for index(). Update build of libc.a (and libc_pic.a)
|
|
may fail because the archive contains the unwanted index.o.
|
|
(Similarly for strrchr() and rindex().)
|
|
|
|
20090709:
|
|
Native Xorg was upgraded again. Builds will probably fail again
|
|
without a clean objdir, at least for src/external/mit/xorg.
|
|
|
|
20090616:
|
|
Native Xorg was upgraded. Builds will need a clean objdir for
|
|
src/external/mit/xorg. Upgrading a system from sets will not
|
|
work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
|
|
subdirectory has been changed into a file, and this needs to
|
|
be manually "rm -r"'ed before installing xbase.tgz.
|
|
|
|
20090501:
|
|
Several new functions were added to string.h/libc, and this
|
|
can cause autoconf problems during the tool build for people
|
|
who fail to clean out their tools objects properly. If you
|
|
note messages about stpcpy, stpncpy or strnlen accompanying a
|
|
failure during the tool build, clean out all your tools
|
|
objects and start again.
|
|
|
|
20090325:
|
|
The i386 port was switched to i486 default toolchain. This requires
|
|
cleaning your src/tools directory and $TOOLDIR and rebuilding them.
|
|
|
|
20090126:
|
|
The __posix_fadvise50 system call changed assembly stub type. You
|
|
need to 'rm -f __posix_fadvise50.*' in the libc build directory
|
|
to avoid using the old assembly stub.
|
|
|
|
20090202:
|
|
pkg_install now depends on the pkgdb cache for automatic conflict
|
|
detection. It is recommented to rebuild the cache with
|
|
``pkg_admin rebuild''.
|
|
|
|
20090110:
|
|
time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
|
|
1. Make sure your kernel has COMPAT_50 in it. Build and install.
|
|
This is needed even in the MODULAR kernel because there is
|
|
conditionally compiled code in rtsock.c.
|
|
2. make sure build.sh completes and the binaries in a chroot work
|
|
before installing.
|
|
3. If you don't use build.sh and you build directly to root, and
|
|
your build breaks in the middle, don't despair. Make sure headers
|
|
are installed properly, and start building libraries first libc
|
|
and libutil, install them and then continue building all the
|
|
libraries in src/lib and src/gnu/lib and install them. Once
|
|
the new libraries are installed, you can restart the build.
|
|
4. If you compile packages and you notice link time warnings,
|
|
rebuild the required packages to update their shared libraries.
|
|
Any package you rebuild will require rebuilding all the packages
|
|
that depend on it.
|
|
5. Next time you run pwd_mkdb with the new binary, the file
|
|
will be upgraded and it will not be backwards compatible.
|
|
6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
|
|
lastlogx(5)) have been versioned, and there is a heuristic
|
|
for utmp. You are better off removing the old files after
|
|
upgrading. The automated clearing of /var/run during
|
|
boot, and the automated rotating of files in /var/log by
|
|
newsyslog(8), may mean that you do not have to remove the
|
|
files manually.
|
|
7. The optional accounting file (/var/account/acct, see
|
|
accton(8)) has not been versioned, and will need to be
|
|
removed. The automatic rotation of the accounting file by
|
|
/etc/daily limits the bad consequences of failure to remove
|
|
the file.
|
|
8. Application software that writes time_t to binary files on
|
|
disk will break or need attention. Most notably: if you are
|
|
using PostgreSQL < 8.4, you need to dump your databases,
|
|
rebuild PostgreSQL with the new time_t, then restore.
|
|
|
|
20081219:
|
|
config(1) has been updated, and one of the files it creates -
|
|
swapnetbsd.o - has changed format. You need to rebuild config
|
|
(done automatically by build.sh) and then you need to rerun
|
|
config on all kernel configuration files before rebuilding those
|
|
kernels.
|
|
|
|
20081205:
|
|
If you build with MKX11=no, you should remove /etc/rc.d/xdm and
|
|
/etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
|
|
set and will appear as extra files for MKX11=no update builds.
|
|
|
|
20081122:
|
|
On i386, various kernel options(4) in GENERIC including
|
|
file systems have been disabled and moved into kernel modules.
|
|
Before trying a new GENERIC kernel, you have to prepare the
|
|
following files as well as a new GENERIC kernel:
|
|
|
|
- build and install kernel modules from src/sys/modules
|
|
|
|
- install the latest bootloader, which will load a module
|
|
for the file system from which the kernel is loaded automatically
|
|
|
|
If you have to load your kernel from a file system which is not of
|
|
the same type as the root file system, you have to load the necessary
|
|
file system module manually on the boot prompt or in the boot.cfg file.
|
|
|
|
20080827:
|
|
If you built and installed a libc from sources between
|
|
2008/08/20 and 2008/08/26 you got a broken strtouq(3)
|
|
which results in false errors reported by lint(1).
|
|
Since this breaks the libc build itself, manual help is
|
|
needed -- lint must be disabled temporarily, e.g.:
|
|
$ (cd lib/libc && make MKLINT=no dependall install)
|
|
|
|
20080813:
|
|
MKDEBUG build was broken because the .depend files did not know
|
|
about .go files. You need to remove all .depend files and rebuild.
|
|
|
|
20080802:
|
|
A regression in binary compatibility for pthread_mutex_t has
|
|
been fixed. Unfortunately, the price is breaking compatibility
|
|
for -current.
|
|
|
|
Threaded programs (using libpthread) and C++ programs (using
|
|
libstdc++) compiled after 20070907 and before 20080802 need to
|
|
be recompiled.
|
|
|
|
One way to find affected pkgsrc packages:
|
|
|
|
$ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO
|
|
$ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO
|
|
|
|
20080731:
|
|
WAPBL (metadata journaling support) has been added, but at this
|
|
time isn't backwards compatible with pre-WAPBL aware kernels
|
|
and userland (fsck_ffs in particular). Please make sure you
|
|
don't use a journaled filesystem with an older kernel/userland,
|
|
especially an uncleanly mounted journaled filesystem. WAPBL
|
|
also requires the super block to be in the UFS2 format. You
|
|
can use fsck_ffs -c 4 to update the superblock format.
|
|
|
|
20080721:
|
|
Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
|
|
isn't defined.
|
|
|
|
20080531:
|
|
The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
|
|
from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
|
|
utility needs to be rebuilt and reinstalled as older binaries
|
|
won't work correctly. The following sequence of commands:
|
|
|
|
$ (cd sys/sys/ && nbmake-$arch includes)
|
|
$ (cd sbin/drvctl/ && nbmake-$arch clean)
|
|
$ (cd sbin/drvctl/ && nbmake-$arch all)
|
|
|
|
leaves new drvctl utility in sbin/drvctl build directory.
|
|
|
|
20080503:
|
|
The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
|
|
|
|
20080521:
|
|
For a while, unprivileged UPDATE builds would fail to
|
|
succeed at the checkflist stage, complaining that
|
|
${DESTDIR}/stand/<arch>/ did not exist. A fix for this
|
|
problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
|
|
If you already hit this problem, update the .mk file,
|
|
remove ${DESTDIR}/stand/<arch>, and re-run the build.
|
|
|
|
20080303:
|
|
Linker warnings are now fatal if $WARNS>0.
|
|
|
|
20080126:
|
|
The posix_fadvise system call has been changed from an assembly
|
|
stub, to a c file that calls an assembly stub. You need to
|
|
'rm -f posix_fadvise.* .depend' in the libc build directory to
|
|
avoid using the old assembly stub.
|
|
|
|
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 appropriately 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 ${MACHINE_GNU_ARCH}-install. It
|
|
calls the target-specific strip program, and the logic to pass
|
|
down STRIP from make has been removed. This requires a
|
|
re-installation of tools.
|
|
|
|
20070422:
|
|
The way OS emulations lookup filenames inside the emulation root
|
|
has been changed. Rather than modify the pathname (and copy back
|
|
to userspace) namei() and lookup() directly check the emulation
|
|
root. One side effect is that absolute symlinks inside the emulated
|
|
root file system will be relative to that file system - unless they
|
|
start /../ this is useful when the emulated root is a real install
|
|
that has such links.
|
|
This might affect symlinks that have been added to reference outside
|
|
the emulated root.
|
|
|
|
20070412:
|
|
The pckbc driver on sgimips IP32 has been removed. Use macekbc
|
|
instead. See the GENERIC32_IP3x kernel configuration for an
|
|
example.
|
|
|
|
20070319:
|
|
src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
|
|
on many platforms due to incorrect flags settings. If you
|
|
updated and built after about 20070315, do "nbmake-$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/

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.

The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
|
|
available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.

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.

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.

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 are 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.
|
|
|

echo Unable to find sources

|

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
|
|
|
|
Symptom:Update build fails in src/tools/gcc complaining that a variable
|
|
(e.g. CPPFLAGS) has changed since the previous run.
|
|
Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
