User and Reference Guide for the Intel® Fortran Compiler 14.0
Before you invoke the compiler, you need set certain environment variables that define the location of compiler-related components.
The Intel® Fortran Compiler includes a shell script that you can run to set environment variables.
The following information is operating system dependent.
Set the environment variables before using the compiler. You can use the source command to execute the shell script compilervars.sh or compilervars.csh. You can also type the location of the shell script, beginning with ./.
//# syntax: source /<install-dir>/bin/compilervars.sh <arg> ./<install-dir>/bin/compilervars.sh <arg> //# examples: (assuming <install-dir> is /installed/compiler/) prompt> source /installed/compiler/bin/compilervars.sh ia32 prompt> ./installed/compiler/bin/compilervars.sh ia32 // OR //# syntax: source /<install-dir>/bin/compilervars.csh <arg> ./<install-dir>/bin/compilervars.csh <arg> //# examples: (assuming <install-dir> is /installed/compiler/) prompt> source /installed/compiler/bin/compilervars.csh ia32 prompt> ./installed/compiler/bin/compilervars.csh ia32
The environment script file requires an architecture argument <arg>:
The default install path is /opt/intel/bin/<version>/ if the installation was conducted by the root user, where <version> is the version of the compiler you wish to set the environment for.
If you want the script to run automatically, add the same command to the end of your startup file.
Sample .bash_profile entry for compilervars.sh for IA-32 architecture only:
Symbolic links are created in the /opt/intel directory at install. The environment variables using symbolic links; however, if two versions of the Intel® Fortran Compiler are installed, the most recently installed version will be symbolically linked.
If the proper environment variables are not set, and error similar to the following will appear when attempting to execute a compiled program:
./a.out: error while loading shared libraries: libimf.so: cannot open shared object file: No such file or directory
Under normal circumstances, you do not need to run the compilervars.bat batch file. The Intel® Fortran command-line window sets these variables for you automatically.
To activate the command-line window, select from the Command Prompt folder is available from the Start > All Programs > Intel Parallel Studio XE 2013 folder.
You will need to run the batch file if a command-line window is opened without using one of the provided menu items in the Start Menu, or if you want to use the compiler from a script of your own.
The batch file inserts the directories used by the Intel® Fortran Compiler at the beginning of the existing paths. Because these directories appear first, they are searched before any directories in the path lists provided by Windows* OS. This is especially important if the existing path includes directories with files having the same names as those needed by the Intel® Fortran Compiler.
If needed, you can run compilervars.bat each time you begin a session on Windows* OS systems by specifying it as the initialization file with the PIF Editor.
The batch file takes two arguments:
<install-dir>\bin\compilervars.bat
<arg1> [<arg2>] where
<arg1> is one of the following:
intel64: Compiler and libraries for Intel® 64 architecture only (host and target)
<arg2>, is optional. If specified, is one of the following:
If <arg2> is not specified, the script uses the version of Visual Studio* that was detected during the installation procedure.
