Intel® Fortran Compiler XE 13.1 User and Reference Guides
Another way to organize source code used by several projects is to build a static library (for Windows* OS, .lib and for Linux* OS and OS X*, .a) containing the object files for the reused procedures. You can create a static library by doing the following:
From the Microsoft Visual Studio* integrated development environment (IDE), create and build a Fortran Static Library project type.
From the command line, use the ar command (on Linux OS and OS X*) or the LIB command (on Windows OS).
After you have created a static library, you can use it as input to other types of Intel Fortran projects.
