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.
A typical stereo recording is made for reproduction on loudspeakers. That is,
the stereo mix is often made with the assumption that sound from one channel
will be heard in both ears. This is not usually the case with headphone
reproduction. The Bauer stereophonic-to-binaural DSP (bs2b) is designed to
improve headphone listening of stereo audio recordings by reproducing this
effect: some of the sound from each channel also goes to the opposite ear,
arriving a short time later (as extra distance is travelled), with a bit of
high frequency roll-off for the shadowing effect of the head, and additional
time delay for low frequencies than high frequencies.
