Hybrid Ada-Fortran Programming on Pentium Box ???

Hybrid Ada-Fortran Programming on Pentium Box ???

[David Smith]

I have a hybrid program consisting of both Ada-83 and Fortran-77 elements.
This program has previously been compiled and linked on both DEC (open
VMS) and SGI equipment. We wish to port to a Pentium box, preferrably
running Windows NT. Is there an Ada compiler that is compatible with
PowerStation Fortran? The Ada FAQ doesn't address this topic.

It depends on the linker that your Fortran compiler uses. Most NT Ada
compilers use Microsoft C++'s linker (Rational VADS and Alsys are two
examples). If your Fortran compiler produces object files that are 
compatable with Microsoft's linker, you're in business.

On the other hand, I believe GNAT uses its own (actually, gcc's) linker.
This would probably make it compatable with any gcc-Fortran port to NT,
if there is such a thing.

One extra word of advice; I suggest starting the NT port from the SGI
version, not the VMS version. In my experience, NT's internals are a
lot closer to UNIX's internals than to VMS's.
