The Intel® Fortran Compiler compiles Fortran source files for Intel® 64 and IA-32 architectures.


Before you can use this tool, you must first set the environment variables by running the environment script as described in the edition-specific Getting Started documentation.

Using the Command Line

To invoke the compiler from the command line, use a command similar to the following:

ifort my_source_file.f90

Following successful compilation, the compiler creates an executable file in the current directory.
