I have a big problem with "Borland C++ Buiolder 6" & FORTRAN90 (Fortan power station 4). I have to use a FORTRAN 90 subroutine. I use this line in my C++ program:
extern "C" subroutine_name_(variable);
but there is a problem in compiling the program. I recive this error massage:
[Linker Error] Unresolved external 'subroutine_name' referenced from C:\PROJECT\subroutine_name.OBJ
any help is appreciated.
