Getting Started with the Intel(R) Fortran Compiler Professional Edition for Linux* OS

Document number: 307058-005US

The Intel(R) Fortran Compiler 11.0 compiles Fortran source files on Linux* operating systems. The compiler is supported on IA-32, Intel(R) 64, and IA-64 architectures.

The Intel Fortran Compiler operates only from the command line on Linux operating systems.

Start the Compiler from the Command Line

Start using the compiler by performing the following steps:

  1. Open a command prompt.
  2. Set the environment variables for the compiler.
  3. Invoke the compiler.

One way to set the environment variables prior to invoking the compiler is to "source" the compiler environment script, ifortvars.sh (or ifortvars.csh):

source <install-dir>/bin/ifortvars.sh <arg>
 

where <install-dir> is the directory structure containing the compiler /bin directory, and <arg> is the architecture argument listed below.

The environment script takes an argument based on architecture; valid arguments are as follows:

To compile a Fortran source file (for example, my_source_file.f90), use the following command:

ifort my_source_file.f90
  

Following successful compilation, an executable named a.out is created in the current directory.

Using Intel(R) Performance Libraries

The Intel(R) Fortran Compiler includes the following performance libraries. Refer to the appropriate sections of the documentation listed for information about using these libraries.

Performance Libraries See the...
