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.
RetroArch is the reference frontend for the libretro API. Popular examples
of implementations for this API includes videogame system emulators and game
engines, but also more generalized 3D programs. These programs are
instantiated as dynamic libraries, or "libretro cores".
libretro is an API that exposes generic audio/video/input callbacks. A
frontend for libretro (such as RetroArch) handles video output, audio
output, input and application lifecycle. A libretro core written in portable
C or C++ can run seamlessly on many platforms with very little/no porting
effort.
RetroArch attempts to be small and lean, while still having all the useful
core features expected from an emulator. It is designed to be very portable
and features a gamepad-centric UI. It also has a full-featured command-line
interface.
