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.
OpenFst is a library for constructing, combining, optimizing, and
searching weighted finite-state transducers (FSTs). Weighted
finite-state transducers are automata where each transition has an input
label, an output label, and a weight. The more familiar finite-state
acceptor is represented as a transducer with each transition's input and
output label equal. Finite-state acceptors are used to represent sets of
strings (specifically, regular or rational sets); finite-state
transducers are used to represent binary relations between pairs of
strings (specifically, rational transductions). The weights can be used
to represent the cost of taking a particular transition.
