How do I get started with the Intel® Fortran Compiler for Windows?

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*.

Prerequisites

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

Building a Binary

To use the Intel® compiler:

1. Launch Microsoft Visual Studio*.
2. Select File > New > Project.
3. In the New Project window, select a project type under Intel(R) Visual Fortran.
4. Select a template and click OK.
5. Select Build > Build Solution.
   The results of the compilation are displayed in the Output window.

Setting Compiler Options

1. Select Project > Properties. The Property Page for your solution appears.
2. Locate Fortran in the list and expand the heading.
3. Step through the available properties to select your configuration.

Using the Command Line

Follow these steps to invoke the compiler from the command line:

• Open a command prompt.
  1. Windows 10
     Open the Start menu, and under the Intel Parallel Studio XE 2019 product group, select a compiler command prompt.
     
     
  2. Other versions of Windows*
     Open the Start menu and under Intel Parallel Studio XE 2019 > Compiler and Performance Libraries > Command prompt with Intel Compiler, select a build environment.
     
     
• Invoke the compiler as follows:
  1. ifort [options... ] inputfile(s) [/link link_options]
  2. Use the command ifort /help to display all available compiler options.
