<li><p>The build requires having a compiler that supports Ada, C and C++.
The Ada front-end is written in Ada so an Ada compiler is needed to
build it. Compilers known to work with the

The LLVM parts of llvm-gcc are written in C++ so a C++ compiler is
needed to build them. The rest of gcc is written in C.
Some linux distributions provide a version of gcc that supports all
