The Intel® Fortran Compiler compiles Fortran source files for Intel® 64 and IA-32 architectures.
Start using the compiler from the command line or within Microsoft Visual Studio*.
You must have a version of Microsoft Visual Studio* installed to use the compiler.
The compiler integrates into the following versions of Microsoft Visual Studio*:
- Visual Studio* 2019
- Visual Studio* 2017
- Visual Studio* 2015
For full functionality within Visual Studio, including debugging and development, Visual Studio* Community Edition or higher is required. Visual Studio* Express Edition allows only command-line builds. For all versions, Microsoft C++ support must be selected as part of the Visual Studio install. For Visual Studio* 2015 and later, you must use a custom install to select this option.
You typically do not need to set the environment variables on Windows*, as the compiler command-line window sets these variables for you automatically. But if you need to set the environment variables, run the environment script as described in the edition-specific Get Started documentation.
Using Microsoft Visual Studio
