Compilation of Ada under FreeBSD

[Frédéric PRACA]

Hello,
I'm trying to build a cross-compiler for RTEMS. Building C or C++ cross-compiler
is not a problem but building the Ada compiler does'nt work. In fact, even
building a normal compiler does'nt work at all. The main reason I found is that
the gcc driver of FreeBSD doesn't support ada and it seems that GNAT is not
sufficient. How can I do ?

Thanks

Fred
