'Lo.

I just tried to compile the vanilla GNAT-GPL 2009 sources today and
came across the following error:

The actual GNAT part of the compiler appeared to compile without issue, using
the compiler from the lang/gnat-gcc44 port. The above, however, seems to be
a problem with the GCC core. It looks very i386 to me...

There doesn't appear to be any explicit support for FreeBSD amd64/x86_64
in those GCC sources as far as I can tell and not being very familiar with
the GCC codebase, I'm not sure how much work it'll be to add them.

Any ideas?

I guess I'm confused. Why is it using config/i386 if it is
trying to build x86_64? Check the port to see if it forces
target i386...

Oh, this wasn't your port, this was just the vanilla source package
taken from libre.adacore.com.

The port has some extra complexity (downloading bootstrap
binaries, etc) that I wanted to avoid until I knew it actually
built without (much) modification.

Oh, I see. Did you configure it with host=i386-unknown-freebsd
and target=amd64-unknown-freebsd (or is it x86_64?)?

It looks like libgcc might not have support for x86_64
FreeBSD??

Full configure line was:

../src/configure \
--enable-languages="c,ada" \
--disable-libada \
--host=x86_64-unknown-freebsd7.2 \
--target=x86_64-unknown-freebsd7.2 \
--build=x86_64-unknown-freebsd7.2

....which is more or less what I build GCC with.

It does seem as if support is missing - perhaps removed by AdaCore?

The system compiler is at 4.2.1 on my AMD64 machine, so I'm guessing
that support was there and was removed?
