Fortran to call Ada

Fortran to call Ada

[Peter Hermann]

I would be grateful if somebody could inform me about experiences:
A large Fortran-system to call a subsystem written in Ada.
The main program should be (must be) Fortran due to several reasons.

My own experiences, very short:
Experimenting with GNAT, I managed to produce an executable
on SGI with the successful link step done by 
"f77 *.o libgnat_all_gathered_on_my_own.a" 
(this did not work under DECalphaOSF/1, however).
gnatlink made problems, too.
All the fortran types offered in package interfaces.fortran
(except complex) were in the param list
but i had a couple of incompatibilies, presumably in the 
parameter handling of native SGI and gcc.
Some worked, some did not, especially when returning to the
calling Fortran routine.
