The Intel® C++ Compiler compiles C and C++ source files for Intel® 64 architecture.

Start using the compiler from the command line or within Xcode*.

Prerequisites

Before you can use this tool, you must first set the environment variables by sourcing the environment script as described in the edition-level Getting Started documentation.

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 Xcode*

You must first create or choose an existing Xcode* project. These instructions assume you are using an existing project.

  1. Select the target you want to change and click Build Rules.

  2. Add a new rule by clicking a + button or using Editor > Add Build Rule.

  3. Under Process, select C source files or C++ source files depending on the source files.

  4. Under Using, select ICC Intel® C++ Compiler 17.0.

  5. Select the target to be built in the project editor under Targets.

  6. Select Product > Build.
