some existing COMPILER lines with arch restrictions etc. In the usual
case this is now using "COMPILER = base-clang ports-gcc base-gcc" on
ports with c++ libraries in WANTLIB.
This is basically intended to be a noop on architectures using clang
as the system compiler, but help with other architectures where we
currently have many ports knocked out due to building with an unsuitable
compiler -
- some ports require c++11/newer so the GCC version in base that is used
on these archirtectures is too old.
- some ports have conflicts where an executable is built with one compiler
(e.g. gcc from base) but a library dependency is built with a different
one (e.g. gcc from ports), resulted in mixing incompatible libraries in the
same address space.
devel/gmp is intentionally skipped as it's on the path to building gcc -
the c++ library there is unused in ports (and not built by default upstream)
so intending to disable building gmpcxx in a future commit.
The situation is this: even when we --disable-gtk-doc, if gtk-doc is
actually installed at configure stage, tools like gtkdoc-rebase will be
picked up and run during the install target. That is bad because the
gtk-doc package may have been removed by then, especially during dpb(1)
bulks (we explicitely disable support for it so why should it stay...).
So for now, let's add the following env to configure whenever we use
--disable-gtk-doc, until a bettersolution is found...
CONFIGURE_ENV +=ac_cv_path_GTKDOC_CHECK="" \
ac_cv_path_GTKDOC_REBASE="" \
ac_cv_path_GTKDOC_MKPDF=""
