Trying to build Gnat on MACOSX 10.5 PPC

Trying to build Gnat on MACOSX 10.5 PPC

[Paul Onions]

Has anyone had any success in building Gnat from the GCC sources on a
MACOSX 10.5 (Leopard) PowerPC machine?

I'm trying to build GCC 4.4.3 with Ada support, but so far with no
success. I have tried bootstrapping from the GnatPPC-4.3.dmg binary
from macada.org and also from the gnat-gpl-2009-43-powerpc-apple-
darwin8.11.0-bin.tar binary from gnuada.sourceforge.net, but both
result in the same error in stage 2 of the bootstrap process, ending
in:

Which looks to me like the first time the newly built compiler is used
to compile an Ada file, it fails completely.

BTW I also get this error when I try to build from MacPorts.

I have used the above mentioned binaries to build simple hello-world
Ada executables, and they seem to work, but both give warnings about
missing symbols. Could this be related to my problems?

Do these problems also occur with Intel machines, or is it restricted
to PPC only? I've googled a lot over the past few days, and the whole
Leopard/Snow-Leopard Intel/PPC scene  seems to be very unclear (at
least to my newbie eyes).

Any help greatly appreciated,
Paul

Just tried bootstrapping with GNAT/GPL 2006 from AdaCore,
and it does get further -- to stage 3 -- but fails in the same way
on the same file.

I'm sure this should tell me something, but I have no real experience
in compiling GCC from source, so I don't understand what this means.

Anyone else know?

You might try inquiring at the list at macada.org.

That's good news. I need it to work there when I finish
my C to Ada rewrite.

On a related note, where's the best place to get it for
Solaris?  I see the site:

  http://gnuada.sourceforge.net/pmwiki.php/Install/Solaris

but it's most recent update seems to be 2007.
