unresolved external symbols in cygwin

I am compiling an application that uses both c and fortran source code within cygwin. I keep encountering mulitple unresolved external symbols at the linking stage.
I am using ifort for fortran compilation and cc (cygwin) for c compilation. The unresolved symbols are defined in c (which compiles and generates the .o file) When I pass this file to ifort it generates the .obj file. However, linking this .obj file fails and claims the c functions are unavailable (unresolved).

How can I solve this problem?

Thank you

Intel Fortran does not support linking with object code from C compilers other than Microsoft Visual C++ or Intel C++. I assume you are using gcc?

Try using MSVC (cl) instead. Or do a "dumpbin -symbols" on the C and Fortran objects and look to see if the desired names match.
