The Intel® Fortran Compiler 9.1 compiles Fortran source
files on Linux* systems. The compiler is supported
on IA-32, Intel
The Intel Fortran Compiler operates only from the command line on Linux systems.
The default root installation path for the Intel Fortran Compiler is /opt/intel/fc/9.1.xxx, where xxx represents a 3-digit build number. On Intel EM64T systems, the path is /opt/intel/fce/9.1.xxx. The term <install-dir> is used in the documentation to refer to this default installation path.
The compiler documentation is installed under <install-dir>/doc/. See the Documentation Index (Doc_Index.htm) for a short description of each documentation component.
You must "source" the compiler environment script, ifortvars.sh (or ifortvars.csh), to set the environment variables prior to invoking the compiler:
To compile a Fortran source file (for example, my_source_file.f90), use the following command:
Following successful compilation, an executable named a.out is created in the current directory.
The Intel compiler also includes man pages. After sourcing the environment script, open the man page to view a complete list of compiler options:
You can read a summary of compiler options from the command line by invoking the compiler with the -help option:
