with two different versions of py-sip; the old one configured to only
produce the module for py-qt5 (in devel/py-sip) and the actual sip in
x11/py-sip-qt5, with broken update chain and which didn't entirely
make sense.
in particular: py-sip is now actually (a newer version of) sip again,
with py2 support dropped (current versions don't have it). other ports
using this are changed to the newer build system using "sip-build"
where possible.
for the future we will need to move to sip 6.x which drops the older
build system using the "sip5" or "sip" script; other ports (veusz, and
i think qgis) don't work with that yet.
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.
