  • 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. Appropriate Ada compilers are gcc-4.2 (or earlier) or the - 2006 GNAT GPL Edition - (or earlier). As a general rule, the Ada compiler used for the - build must not be more recent than the Ada compiler it is building. - This is why the build fails with gcc-4.3 and the 2007 GNAT GPL Edition. + build it.

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 - 2006 GNAT GPL Edition) + 2005 GNAT GPL Edition) and another which supports C++, see below.

  • Because the Ada front-end is experimental, it is wise to build the - compiler with checking enabled. This causes it to run slower, but + compiler with checking enabled. This causes it to run much slower, but helps catch mistakes in the compiler (please report any problems using LLVM bugzilla).
