Intel® Parallel Studio XE 2019: Get Started with the Intel® C++ Compiler 19.0 for Linux*

The Intel® C++ Compiler compiles C and C++ source files for Intel® 64 and IA-32 architectures.

Start using the compiler from the command line or within the Eclipse* C/C++ Development Toolkit (CDT).

Prerequisites

Before you can use this tool, you must first set the environment variables by sourcing the environment script using the initialization utility to initialize all the tools in one step:

From a command prompt or script, cd to <install_dir>/parallel_studio_xe_2019.<update number>.<package number>\bin

By default, <install_dir> is:
- For root installations: /opt/intel
- For non-root installations: $HOME/intel
Enter source psxevars.sh or source psxevars.csh.

Using the Command Line

To invoke the compiler from the command line, use a command similar to the following:

For C source files: icc my_source_file.c
For C++ source files: icpc my_source_file.cpp

Following successful compilation, the compiler creates an executable file in the current directory.

Start from the Eclipse* CDT

The Intel® C++ Compiler for Linux* provides integrations for the compiler to Eclipse* and CDT that let you develop, build, and debug your Intel® C/C++ projects in an integrated development environment (IDE).

Note: Eclipse* and CDT are not bundled with the compiler. You must obtain them separately.

You must first install and configure Eclipse* on your system and then configure Eclipse* to use the compiler. To install Eclipse*, refer to the Eclipse* documentation.

To configure Eclipse* to use the Intel compiler:

Start Eclipse*.
Select Help > Install New Software.
Next to the Work with field, click the Add button. The Add Site dialog opens.
Click the Local button, and browse to <install_dir>/ide_support_2019/eclipse/compiler_xe.

Note The default path for <install-dir> is /opt/intel/.
Click OK.
Deselect Group items by category.
Select the options beginning with Intel, and click Next.
Follow the installation instructions.
When asked if you want to restart Eclipse*, select Yes.

When Eclipse* restarts, you can create and work with CDT* projects that use the compiler.

To invoke the compiler from Eclipse*:

Open your project.
Select the project in the Project Explorer.
Select Project > Build Project.
