C++ source of GANT compiler ???

C++ source of GANT compiler ???

[Manuel Baz]

We need  to make a GNAT compiler on DG/UX from source files, the source
files of
GNAT version 3.11 are Ada95 , but we don't have a Ada95 compiler on this
platform.

We do have C++ compiler on DG/UX.

Please , where could we get the C++ source of GNAT Compiler (any
version) ???

Thanks in advance.

I think you will have to create a cross compiler. Use the gcc and gnat source
and compile the code on a supported plattform. And make sure dg/ux is the
target. Exactly how to do it I don't know. You may have to read up on the
process.

Yes, this is the correct approach. It is not that hard! 

Contact ACT for support in doing this; they often put a lot of effort
into evaluation support for potential customers. They may also have
such a port in the works. Just send an email to 'sales@gnat.com'; the
worst that could happen is they say "no thanks" !

I seriously doubt there *ever* was C++ source for Gnat. The C++ language
was still under development while Gnat was being created back in the
'93-'94 time frame. I think Gnat was already self-hosted (iow: Compiled
using Gnat) when I first came in contact with it back in '94. There may
once have been C code that compiled a very minimal version of the
language, but that would be long gone by now.

At that time C++ was already a used and usable language, well... as
much usable as today.

I'm quite sure that gnat was first compiled with Ada83 compilers and
so that there was never a C or C++ version.

No, the original versions of the GNAT front end were written in Ada 83.

Of course, the back end was and is written in C.

The GNAT front end was always 100% Ada, it started life by
being bootstrapped using Alsys Adaworld on a Sun Sparc. There
never was and likely never will be C nor C++ code for GNAT
(what would be the point?) There is no need, since cross-
compilation works fine for moving to new platforms.
