$NetBSD: UPDATING,v 1.78 2002/12/04 12:50:43 lukem Exp $
|
|
|
|
This file is intended to be a brief introduction to the build
|
|
process and a reference on what to do if something doesn't work.
|
|
|
|
For a more detailed description see Makefile.
|
|
|
|
Recent changes:
|
|
^^^^^^^^^^^^^^^
|
|
|
|
20021130:
|
|
fparseln(3) moved from libutil to libc.
|
|
If building to DESTDIR=/, reinstall the includes
|
|
and rebuild libc:
|
|
make includes
|
|
make do-lib-libc
|
|
If using build.sh, "cd tools/compat && make clean"
|
|
before rebuilding the tools.
|
|
|
|
20021126:
|
|
The mk.conf(5) variable SYS_INCLUDE has been deprecated,
|
|
including the optional "SYS_INCLUDE=symlinks" support.
|
|
All header files, including <sys/*.h> are copied into
|
|
/usr/include.
|
|
|
|
20021121:
|
|
The C run-time support files crtbegin.o and crtend.o
|
|
(and their companions crtbeginS.o and crtendS.o) were
|
|
split up, with new crti.o and crtn.o files resulting.
|
|
This means that libtool needs to be rebuilt once the
|
|
new libraries are installed. The process of rebuilding
|
|
libtool will cause it to automatically notice the new
|
|
required files, but it *must* be rebuilt in order to
|
|
do this.
|
|
|
|
An out-of-date libtool will result in shared libraries
|
|
which lack _init() and _fini() routines, which means that
|
|
their global contructors/destructors will not be invoked.
|
|
|
|
20021121:
|
|
A bug related to how ARM ELF objects were tagged has been
|
|
corrected.
|
|
|
|
NetBSD ARM ELF uses the soft-VFP floating point model by
|
|
default. However, the assembler lacked support for marking
|
|
objects as using the VFP floating point format, and the
|
|
compiler was no properly passing the flag indicating "soft-VFP"
|
|
to the assembler.
|
|
|
|
Unfortunately, this means that the linker will now consider
|
|
old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
|
|
incompatible with new (properly marked) objects.
|
|
|
|
The problem will only manifest itself if you attempt to compile
|
|
a new program using the fixed toolchain, and link that program
|
|
against old libraries which do not have the proper "softvfp"
|
|
markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
|
|
WILL CONTINUE TO WORK PROPERLY.
|
|
|
|
The only work-around for the problem is to recompile all of
|
|
the libraries on the system. The easiest way to do this for
|
|
system libraries is to install a binary snapshot; there are
|
|
generally available on releng.netbsd.org. Any packages you
|
|
have installed which supply libraries will have to be recompiled
|
|
if you wish to link new programs against those libraries.
|
|
|
|
If you have questions about this matter, please contact
|
|
port-arm@netbsd.org.

|
|
|
20021011:
|
|
Systrace has been improved to support privilege elevation.
|
|
Updating the kernel requires the userland part of systrace
|
|
to be rebuild.
|
|
|
|
20021010:
|
|
The config(8) grammar was changed to allow options to register
|
|
dependencies on attributes, as well as other options. Users
|
|
must update and reinstall usr.sbin/config before building a new
|
|
kernel.
|
|
|
|
20021009:
|
|
A new attribute dependency syntax was introduced to config(8),
|
|
which is now used by the SCSI configuration description. Users
|
|
must update and reinstall usr.sbin/config before building a new
|
|
kernel.
|
|
|
|
20021003:
|
|
Several changes have been made to the autoconfiguration
|
|
framework. Users must update and reinstall usr.sbin/config
|
|
before building a new kernel.
|
|
|
|
20021001:
|
|
The i386mp branch has been merged. To compile a kernel, users
|
|
will need to add the option 'cpu* at mainbus?' to their configuration
|
|
file. Multiprocessor kernels will need
|
|
ioapic* at mainbus? apid ?
|
|
options MULTIPROCESSOR
|
|
options COM_MPLOCK
|
|
|
|
20020922:
|
|
MKDYNAMICROOT=yes enabled by default, which means that
|
|
certain shared libraries are installed into /lib, the shared
|
|
linker is installed into /libexec, and all programs in /bin
|
|
and /sbin are dynamically linked.
|
|
If you do not use "make build", you should ensure that
|
|
you have the libraries and shared linker in the new locations,
|
|
with:
|
|
make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
|
|
|
|
20020917:
|
|
USE_NEW_TOOLCHAIN has been replaced with:
|
|
- TOOLCHAIN_MISSING -- set to "yes" on platforms for which
|
|
there is no working in-tree toolchain (hppa, ns32k, sh5,
|
|
x86_64).
|
|
- EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
|
|
root ofan external toolchain (e.g. /usr/local/gnu). This
|
|
enables the cross-build framework even for TOOLCHAIN_MISSING
|
|
platforms.
|
|
|
|
20020906:
|
|
gehenna-devsw has been merged into the trunk. Need to update and
|
|
reinstall usr.sbin/config before build the kernel.
|
|
|
|
20020822:
|
|
Crunched rescue tools (contents of /bin and /sbin, plus others)
|
|
are now provided in /rescue.
|
|
|
|
To ensure that these are built statically linked (no matter
|
|
what the setting of LDSTATIC is), use a crunchgen(1) built
|
|
from sources newer than 20020820 (see the next entry).
|
|
|
|
20020820:
|
|
crunchgen(1) changed to ensure that the generated program
|
|
is statically linked.
|
|
|
|
Solution: update and reinstall usr.bin/crunch
|
|
|
|
20020515:
|
|
sshd user/group has been added. Need to hand add this in, or sshd
|
|
will not let you log in (with default, or UsePrivlegeSeparation=yes)
|
|
|
|
Add the following into /etc/group:
|
|
|
|
sshd:*:16:
|
|
|
|
and the following to /etc/master.passwd (via vipw):
|
|
|
|
sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
|
|
|
|
also /var/chroot/sshd directory needs to be present (digged as a part of
|
|
build process).
|
|
|
|
20020426:
|
|
NBUILDJOBS obsoleted in favor of just using -j.
|
|
|
|
20020426:
|
|
etc/postinstall added, which performs various checks for
|
|
configuration file updates and changes, and can fix most of
|
|
the problems identified.
|
|
This should make it much easier to upgrade a system's
|
|
configuration from earlier systems (as far back as NetBSD 1.5).
|
|
|
|
20020320:
|
|
<bsd.lib.mk> needs a new install(1) for it's "-a cmd" support.
|
|
build and install at usr.bin/xinstall before the build.
|
|
|
|
20020319:
|
|
raw IPv6 socket now makes strict checking for sa_family and sa_len
|
|
on send(2) operation. be sure to have sbin/rtsol and usr.sbin/rtsold
|
|
newer than November 2001 when you upgrade the kernel.
|
|
|
|
20020311:
|
|
ssh configuration files were moved from /etc to /etc/ssh. Beware
|
|
if you restart your machine from remote. Note that sshd.conf needs
|
|
to be changed (due to the use of "/etc" inside).
|
|
|
|
20020223:
|
|
Users of the VAX port will need to rebuild and install gas
|
|
so it deal with the now present register prefix used in all
|
|
the VAX assembly files.
|
|
|
|
20020118:
|
|
|
|
ntpd user/group has been added. Need to hand add this in or builds
|
|
will break as mtree aborts early.
|
|
|
|
Add the following into /etc/group:
|
|
|
|
ntpd:*:15:
|
|
|
|
and the following to /etc/master.passwd (via vipw):
|
|
|
|
ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
|
|
|
|
20011207:
|
|
|
|
If you're attempting to build a snapshot on sparc64 and are getting
|
|
reloc errors from the toolchain groff binary this means your native
|
|
toolchain has some broken C++ bits.
|
|
|
|
To fix:
|
|
|
|
Build a new toolchain (i.e. build.sh -t)
|
|
Use the new toolchain to build and install natively (i.e. /usr/lib)
|
|
|
|
gnu/lib/libgcc
|
|
gnu/lib/libstdc++
|
|
|
|
After this a snapshot will be able to be built.
|
|
|
|
20011201:
|
|
In order for a sparc64 build to work you must have a working awk. If
|
|
you've built and installed a system with the new toolchain up to this
|
|
point you do not have a working awk as its ability to do floating
|
|
point is broken.
|
|
|
|
To build:
|
|
|
|
remake and install gnu/lib/libgcc
|
|
remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
|
|
against the new libgcc.a)
|
|
|
|
20011128:
|
|
Kernel config information was changed to use defflag in
|
|
the various "files" files. Bug fixes to config(8) are
|
|
required in order for this to work properly. Make sure
|
|
to build and install in usr.sbin/config before attempting
|
|
to build a new kernel.
|
|
|
|
20011030:
|
|
libc/locale/wcstod.c now needs new lint(1). Update lint(1)
|
|
before building libc.
|
|
|
|
20011029:
|
|
The new document BUILDING.mdoc (view with nroff | more, or
|
|
see pre-generated .txt and .html versions) describes the build
|
|
procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
|
|
build process, are intended in the long run to replace this
|
|
manual update log.
|
|
|
|
Users building a USE_NEW_TOOLCHAIN system should read the
|
|
BUILDING document for caveats. Generally, BUILDING supersedes
|
|
UPDATING for these systems, as tool updating is taken care of
|
|
by the new build system.
|
|
|
|
20011028:
|
|
src/etc/Makefile now needs install to be able to handle
|
|
symlinks that point to nowhere. A bug in install that
|
|
prevented this was corrected.
|
|
|
|
Solution: update and reinstall usr.bin/xinstall
|
|
Better Solution: Use the new toolchain and it will just work
|
|
for you.
|
|
|
|
20011006:
|
|
/etc/mtree/NetBSD.dist has been updated to take advantage of
|
|
absolute path support added to mtree(8). Older mtree(8)s don't
|
|
understand the format.
|
|
|
|
Solution: update and reinstall usr.sbin/mtree
|
|
|
|
20011004:
|
|
Crunchgen has been updated to work via reach-over makefiles. Updating
|
|
is suggested before running a snapshot build
|
|
|
|
20010915:
|
|
The new "ubcperf" code committed by Chuck Silvers removed
|
|
a header file, uvm/uvm_vnode.h. There may be stale .depend
|
|
files that still reference this file.
|
|
|
|
Solution: "make cleandir && make dependall" in affected
|
|
directories.
|
|
|
|
20010803:
|
|
grep.info is now built from grep.texi using makeinfo. Since it
|
|
requires makeinfo v4.0, you need to install new texinfo before
|
|
building gnu/usr.bin/grep. To install new texinfo, please follow
|
|
the instruction described in 20010726 entry.
|
|
|
|
20010803:
|
|
(i386 only): i386 kernel now uses new instructions like
|
|
`fxsave' which old gas doesn't understand. To build the
|
|
kernel successfully, you need to build and install a new toolchain,
|
|
(i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
|
|
from your kernel configuration until you rebuild your userland.
|
|
See 20011029 above and BUILDING file in this directory for more information.
|
|
[updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
|
|
|
|
20010731:
|
|
Bootloader update on ELF platforms. DDB in kernels from before
|
|
this will be unable to read symbol tables provided by newer
|
|
bootloaders.
|
|
|
|
20010726:
|
|
Texinfo was updated to 4.0. To avoid failures when trying to
|
|
build the included texinfo files, do:
|
|
|
|
cd src/gnu/usr.bin/texinfo
|
|
make MKINFO=no dependall install
|
|
|
|
20010718:
|
|
Enabled correct .init/.fini processing in crt0. The way this
|
|
was done was to change a -I directive to cc(1), which means
|
|
make(1) will have a stale dependency (it will be checking the
|
|
timestamp on the wrong "dot_init.h").
|
|
|
|
The symptom you will see is that new programs die with SIGSEGV
|
|
if you have a stale dependency.
|
|
|
|
Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
|
|
before starting your build.
|
|
|
|
20010628:
|
|
A construct was added to uvm_page.h that uncovered a bug
|
|
in lint(1). If you get a warning/error about a non-portable
|
|
bitfield, update your lint(1) before proceeding.
|
|
|
|
20010226:
|
|
Added named user/group to system. Need to hand add this in or builds
|
|
will break as mtree aborts early.
|
|
|
|
To work around add by hand:
|
|
|
|
named:*:14:
|
|
|
|
to /etc/group and add:
|
|
|
|
named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin
|
|
|
|
to master.passwd (use vipw for instance if doing by hand).
|
|
|
|
Now a make build should progress.
|
|
|
|
20010219:
|
|
get/setprogname() added. Any hostprogs that may use this will need
|
|
to be bootstrapped manually until the host system is current.
|
|
|
|
Known problems: sys/arch/macppc/stand/fixcoff
|
|
usr.sbin/config (adding -DMAKE_BOOTSTRAP to
|
|
CFLAGS and rebuilding should work)
|
|
usr.sbin/mdsetimage - Build a static copy if
|
|
building a snapshot before fully bootstrapped.
|
|
|
|
20010204:
|
|
prepare the code to compile with stricter gcc flags. in
|
|
particular start eliminating redundant declarations. Yacc
|
|
needs to be installed before make build.
|
|
|
|
20010114:
|
|
introduce .if commands(target) in make(1). You need to
|
|
bring everything up-to-date first, then without installing
|
|
anything make and install in usr.bin/make, then proceed
|
|
with make build.
|
|
|
|
20010101:
|
|
bsd.subdir.mk committed 20001230 had a bug which caused
|
|
afterinstall targets to run too soon; update again.
|
|
|
|
20001230:
|
|
New share/mk files needed to support .WAIT in SUBDIR variables.
|
|
If you get make errors,
|
|
(cd share/mk; make install)
|
|
Also, PRINTOBJDIR has changed and is now used more heavily.
|
|
|
|
20001019:
|
|
The `ca' device driver has been replaced by `ld'; although the
|
|
major and minor numbers haven't changed, you should update your /dev
|
|
directory.
|
|
|
|
20000929:
|
|
The following make directives are obsoleted.
|
|
MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
|
|
By default, RSA is built into libcrypto. IDEA and RC5 will not be
|
|
built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
|
|
additional library libcrypto_{idea,rc5}.
|
|
|
|
|
|
Hints for a more successful build:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
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:
|
|
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, set the DESTDIR environment
|
|
variable before running make build. It should be set to
|
|
the pathname of an initially empty directory.
|
|
Problems: 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.
|
|
|
|
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---
|

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)
