Found this surprisely hard to get an answer for. I already have MS Visual studio for C/C++/C# programming. I recently purchased Intel fortran and it installed happily into this environment. I have a tiny piece of C that I use with the Fortran to provide SEH. Adding it the project didnt get it compiled. Do I have purchase Intel C/C++ to be able to combine fortran and C together or is there a way to use an object file from the MS compiler instead?
