Getting Started with the Intel® C++ Compiler for Linux*

Document number: 307056-009US

The Intel® C++ Compiler 9.1 compiles C and C++ source files on Linux* systems. The compiler is supported on IA-32, Intel® EM64T systems, and Intel® Itanium®-based systems.

You can run the Intel C++ Compiler from the command line or within the Eclipse* integrated development environment. Eclipse is supported on IA-32 and Itanium-based systems.

The default root installation path for the Intel C++ Compiler is /opt/intel/cc/9.1.xxx, where xxx represents a 3-digit build number. On Intel EM64T systems, the path is /opt/intel/cce/9.1.xxx. The term <install-dir> is used in the documentation to refer to this default installation path.

Locating the Documentation

The compiler documentation is installed under <install-dir>/doc/. See the Documentation Index (Doc_Index.htm) for a short description of each documentation component.

Using the Compiler on the Command Line

You must "source" the compiler environment script, iccvars.sh (or iccvars.csh), to set the environment variables prior to invoking the compiler:

source /opt/intel/cc/9.1.xxx/bin/iccvars.sh

To compile a C language source file (for example, my_source_file.c), use the following command:

icc my_source_file.c

To compile C++ source files, use this command:

icpc my_source_file.cpp

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:

man icc

You can read a summary of compiler options from the command line by invoking the compiler with the -help option:

icc -help

Using the Compiler with Eclipse

If you installed the Eclipse integrated development environment with the Intel compiler, you should "source" iccvars.sh (or iccvars.csh), then run the iccec script to open Eclipse:

source /opt/intel/cc/9.1.xxx/bin/iccvars.sh

iccec

See the Building Applications section in the compiler documentation for more information about using the compiler with Eclipse.
