Re: Help with getting GNAT Ada running on 64-bit Gentoo Linux

["Dwight Schauer" <dschauer@gmail.com>]

I've compiled gcc/gnat 3.4.3 on fedora core 3 prefixed to a different
path than /. I had to disable multilib in order for it to build. The
resulting installation seems to work. I copied it to a gentoo amd64,
and it works on there as well. I tried it with some small ada programs
and they compiled and ran the same as they do on fedora core 3. I'm
having problems using it in the ebuild to bootstrap the cross
compiler. It is not not passing the sanitty check.

I can use that gnatgcc to compile other c programs.

If I set my path to /opt/local-tools/host-gcc-ada-3.4.3/bin/ I can use
gnatmake and what not, but I don't like have a kludged development
environment.

To compile it on fedora core 3 I basically just took the ebuild for
gcc gnat 3.4.3 and hacked it up a bit in regular bash script and
prefixed
it to /opt/local-tools/host-gcc-ada-3.4.3/

While I might be able to use it that way, I'd rather get it working in
the gentoo portage system.
