Re: Problems to link C++ files to a Fortran 77 file

Hi Gustavo,

I bet that all the "API" routines that interface between both FORTRAN and 
C++ need to follow the C ABI and C name-mangling.

On the C++ side, you'll need to make sure the header file has
        #ifdef __cplusplus
        extern "C" {
        #endif
near the top (after any other header file includes), and
        #ifdef __cplusplus
        }
        #endif
near or at the bottom.

Note:  you won't be able to pass std::cout to FORTRAN routines to 
utilize.  If you need to pass std::cout into FORTRAN to be passed through 
back to C++, you''ll need to pass the pointer to std::cout as void* into 
FORTRAN, and then back to the C++ side, you'll have to send back as a 
void*, then static_cast it back on the C++ side.

Sincerely,
