<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

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
three languages (the Ada part often comes as an add-on package to
the rest of gcc). Otherwise it is possible to combine two versions
of gcc, one that supports Ada and C (such as the

+ <a href="http://libre.adacore.com/">2005 GNAT GPL Edition</a>)
