Multi-version Compiler Support

You can select different versions of the
Intel® oneAPI
DPC++/C++
 Compiler
 for compiling projects with the Eclipse Integrated Development Environment (IDE). For a list of the currently supported compiler versions by platform, refer to the Release Notes.
If multiple versions of the compiler are installed on the system, Eclipse uses the latest version by default. To select the version of the compiler to build your project:
  1. Right click the project and open
    Properties
    .
  2. In the properties dialog box, select
    C/C++ Build
    Settings
    .
  3. Select the
    Intel(R) oneAPI DPC++ Compiler
     for a DPC++ project, or the
    Intel® C++ Compiler
     for a C++ project tab.
  4. Select the row with the desired compiler version.
  5. Click
    Use Selected
    . Alternatively, click
    Use Latest
     to select the latest version of compiler.
  6. Click
    Apply
    .
The corresponding compiler environment is configured automatically for your project.
Use
Settings
 and
Tool Chain Editor
 to select tools to be used within the toolchain, or set distinct project properties, like compiler options, to be used with different versions of the compiler.
For any project, you can set the compiler environment by specifying it within Eclipse; this overrides any other environment specifications for the compiler.
