source : Intel® Fortran Compiler Documentation

Getting Started : Using the command Line

Before you invoke the compiler, you need set certain environment variables that define the location of compiler-related components.

Add this to you ~/.bashrc :

source /usr/local/Fortrans/Intel/composerxe/bin/compilervars.sh intel64

Note :

The environment script file requires an architecture argument :
- ia32: Compiler and libraries for IA-32 architecture only.
- intel64: Compiler and libraries for Intel® 64 architecture only.
