Compile Fortran program with IFORT and using object files (i.e. .lib) compiled in Microsoft Visual Studio

I have a basic question that I cannot find the answer to even after searching the web many times.

Is it possible to compile a Fortran program by IFORT that uses (as dependencies) object files (i.e. .lib) that were compiled by Microsoft Visual Studio C?

Yes, it is possible, and is even rather easy. You have several options for how to do this:

  • Add the MSVC library project to your Fortran Visual Studio solution and then use Project > Dependencies to add the C project as a dependent of your Fortran project *does not work if the C project creates a DLL)
  • Add the .lib from the C project to the Fortran project as if it were a source file
  • Name the C .lib in the Linker > Input > Additional Dependencies project property.

I generally recommend the first choice, as it means you don't have to fuss with different settings for Debug and Release projects. You do need to make sure that the C library is built to specify the same run-time library type (Debug vs. Nondebug, DLL vs. Static) as the Fortran project. This is in the Code Generation property page for C.

There is a worked example "Fortran Calls C" in the Intel Parallel Studio XE for Windows Sample Bundle.

You'll also need to understand how to call a C procedure from Fortran and ensure that the C arguments have compatible Fortran types. It works best if you make use of the Fortran standard's "C interoperability" features.
