1.) Always set the "ABI" variable.
2.) Default to 64-bit mode if the machine is able to run 64-bit binaries.
This seems to match the default behavior of Xcode (Apple's toolchain).
3.) Set "LOWER_ARCH" so it automatically evalutes to the correct value
based on the ABI we are compiling for, not on based on the kernel
the machine is running. This even works properly if the ABI is
set in "/etc/mk.conf" or on the command line.
Thanks a lot to OBATA Akio for providing the crucial hint to get
this working properly.
is not defined that early as we have included neither "bsd.own.mk"
nor "mk.conf" yet.
We unfortunately cannot make these adjustments later because "bsd.own.mk"
and "mk.conf" would be processed with an incorrect value for
"MACHINE_ARCH".

The "gnupg" package now builds for the 64-Bit API without extra tricks.
X.Org found in NetBSD-current.
Thanks a lot to all who helped, especially Matthias Scheler who did
repeated tests on Mac OS X and older versions of NetBSD to make sure the
support for those platforms wouldn't be broken (or at least, not fatally,
as I would still expect a few hiccups here and there, because there is
only so much one can test in such limited time).
On the infrastructure side, this branch brings pkgconfig-builtin.mk, in
order to write very easily new builtin.mk files. It can actually handle
more than just pkgconfig files, but it will provide a version if it finds
such a file. x11.builtin.mk has also been made more useful and now all
existing (and future!) native-X11-related builtin.mk files should include
it.
using the += operator, not the simple = operator, in mk.conf. That way
we can mark packages as having open source licenses without disturbing
the users.
separating LOWER_OPSYS and LOWER_OPSYS_VERSUFFIX, since numbers are now
removed from LOWER_OPSYS when forming MACHINE_GNU_PLATFORM.
Fix the remaining to platforms: Interix and IRIX.
into ${LOWER_OPSYS_VERSUFFIX}.
When assigning GNU_MACHINE_PLATFORM, strip numerical characters from
LOWER_OPSYS. (final component is eg. osf5.1 not osf15.1)
and to support the "inet6" option instead.
Remaining usage of USE_INET6 was solely for the benefit of the scripts
that generate the README.html files. Replace:
BUILD_DEFS+= USE_INET6
with
BUILD_DEFS+= IPV6_READY
and teach the README-generation tools to look for that instead.
This nukes USE_INET6 from pkgsrc proper. We leave a tiny bit of code
to continue to support USE_INET6 for pkgsrc-wip until it has been nuked
from there as well.
automatically supply missing "basic" headers and libraries from an
older system, e.g. IRIX 5.x or Interix or AIX, etc.
Example usage:
USE_FEATURES+= snprintf glob regex
For now, we just pull in libnbcompat to supply the missing bits.
- USE_CROSS_COMPILATION activates it, CROSS_DESTDIR specifies root of
the target filesystem
- derive _CROSS_DESTDIR from CROSS_DESTDIR or MAKEOBJDIR
- buildlink3.mk prefixes the files to symlink with _CROSS_DESTDIR
- compiler/gcc.mk knows about the target prefix (e.g. i386--netbsdelf)
- PKG_DBDIR is prefixed with _CROSS_DESTDIR
- package-install and bin-install are not called with su
- install and strip are redirected to the tool version
- links for the target specific ar, as, ld, nm, objdump, ranlib and
strip are added
- compiler wrapper detect if linking is requested or not
- special command sinks for CPP and CC/CXX add the cross-compile magic:
- modify include dirs to get the target /usr/include
- modify linker dirs and runpath to use target /usr/lib at link time,
but keep correct rpath entries

Basic tests by he@ on Sparc. Review from jlam@.
cross-compile support.
- NATIVE_MACHINE_GNU_ARCH, NATIVE_LOWER_ARCH, NATIVE_MACHINE_ARCH,
NATIVE_MACHINE_PLATFORM and NATIVE_MACHINE_GNU_PLATFORM work
like the counterpars without NATIVE_ prefix. Expansion of
NATIVE_LOWER_ARCH and NATIVE_MACHINE_ARCH is enforced early,
so that MACHINE_ARCH can be overriden in mk.conf to specify the
target architecture.
- Provide a default of NO for USE_CROSS_COMPILE. This will be the
main switch to activate cross-compiling and adding it now makes
it possible to merge more of the patches for specific packages.
- Set --build and --host when cross-compiling, the former using the
just added variable NATIVE_MACHINE_GNU_PLATFORM.
