wrappers when USE_CWRAPPERS is enabled, saving a reasonable amount of
I/O during builds, mostly due to avoiding the transform/untransform sed
file generations.
WRAPPER_DIR and WRAPPER_BINDIR are used by various packages to override
or point to specific wrappers, and these now point to the cwrappers
directory when enabled, removing the need for CWRAPPERS_BIN_DIR
duplication and fixing packages which previously were using legacy
wrappers by accident.
A number of targets are now duplicated between bsd.wrapper.mk and
cwrappers.mk, the intention being that the legacy wrappers will be
deprecated once cwrappers is verified on all supported platforms. If
that turns out to take longer than expected, we will probably want to
introduce a wrapper.mk to abstract them away before loading the
appropriate back-end.
to the same value anyway. Also removes a comment from 2005 which was
possibly wrong at the time it was committed, given the same construct
has been used in bsd.buildlink3.mk unchanged since 2004.
surrounding a list of static libraries, we must preserve that order so the
effect of --whole-archive is as intended by the package.
cwrappers does this correctly but classic wrappers didn't.
This was originally introduced to work around some behaviour in the
libtool build, however these days it is actively harmful for a number of
packages, where removing additional arguments when -v is present on the
command line can break ABI detection (notably in CMake packages).
Instead, filter out any references to BUILDLINK_DIR from the libtool
scripts, as that should do the same job.
Retain the ability to run the 'scan' wrapper script, as it can be useful
in certain cases, and is required to support the scan-libtool script
anyway.
which is accepted by both the GCC bundled with Solaris 10 and the more
modern GCC versions availabe in "pkgsrc". Handling of POSIX thread
related options should be left to pkgsrc anyway.
Fix based on a suggestion by Richard Palo.
All recent packages featuring Ada code have a hard dependency on the
lang/gnat-aux compiler package. The valid values for USE_LANGUAGES
are c, c99, c++, fortran, fortran77, java, objc, so specifying a
specific compiler was necessary up into now.
One problem with lang/gnat-aux is that it is installed at ${LOCALBASE}
where the lang/gccXX compilers are installed at ${LOCALBASE}/gccXX.
The latter compilers have no possibility of sharing conflicting files
unlike lang/gnat-aux. Rather than fundamentally update the GCC 4.6-based
lang/gnat-aux to avoid these conflicts, a new Ada-capable compiler
based on GCC 4.7 was created with the intent of being supported by
mk/compiler.mk and mk/compiler/gcc.mk.
The Ada packages will be effectively migrated from lang/gnat-aux to the
new lang/gcc-aux compiler, but lang/gcc-aux will remain as a standalone
package as it is the only GCC 4.6-based compiler that builds on
DragonFly and serves it as a world and kernel compile option.
In addition to the current language wrappers, lang/gcc-aux adds
wrappers for "ada" (unique to gcc-aux, hardlinked to gcc driver),
and the gnat, gnatmake, gnatbind, gnatlink, gnatchop, gnatprep,
and gnatls programs. Supporting all of these allows the wrapper
system to be used with Ada packages; currently wrappers are mostly
disabled on them.
The lang/gcc47 implicitly adds support for the "objc-c++" language by
adding it to the USE_LANGUAGES list, but it wasn't really supported.
An attempt was made to better support objc-c++, but this new enumeration
probably still needs work or needs to be removed completely.
Logic for Ada support:
1) All lang/gccXX compilers have version numbers ranging from 2.8.1 to 9.
2) lang/gcc-aux uses the release date as its version number in the form of
YYYYMMDD with a minimum value of 20120614, so there is no version
overlap.
3) When at least one element of USE_LANGUAGES is "ada", the value of
20120614 is added to the set of GCC_REQD which selects lang/gcc-aux.
4) The _NEED_NEWER_GCC check is disabled. It fails and isn't relevant;
unless a package sets GCC_REQD over 20120614, the only way to select
lang/gcc-aux is to specify the Ada language and only one compiler
known to gcc.mk can support it.
but our gcc re-orders them so that all -R args come at the front
of the "ld" invocation. This messes up the relative search order,
and is at least partly responsible for "the pixman problem"
experienced on (at least) NetBSD 5.1. This is as close as a general
fix as I can think of, and should fix PR#46130, although it possibly
doesn't fix every instance of this more general problem.
- provide cpp wrapper using cc -E
- provide c++_r wrapper working like c++
- provide -rpath handling for cc
- fix some debug messages to provide the correct script name
- Add cc_r/xlc_r wrapper using the same rules as xlc itself.
It is used for example by Perl.
- Improve the RPATH emulation:
- Always set -blibpath, use /usr/lib:/lib as default
- If -blibpath is exlicitly given, add to the default
- Additionally append any -Wl,-rpath given.
The PKG_FAIL_REASON isn't executed by default, no idea why, but this
makes it a bit cleaner why the compiler wrapper will fail and fixes the
more important AIX case.
