On ports-gcc archs libbz2 was detected automatically because
/usr/local/lib is in the default library path, but the build failed at
compile time because bzlib.h wasn't found in the include search paths.
Initial diff by cwen@, ok sthen@ cwen@
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.
Icarus Verilog is a Verilog simulation and synthesis tool. It operates
as a compiler, compiling source code writen in Verilog (IEEE-1364) into
some target format. For batch simulation, the compiler can generate C++
code that is compiled and linked with a run time library (called "vvm")
then executed as a command to run the simulation. For synthesis, the
compiler generates netlists in the desired format.
