Syntax

Linux:

-fsycl-host-compiler=arg

Windows:

-fsycl-host-compiler=arg

Arguments

arg

Is the compiler that will be the host for compilation.

It can be the name of a compiler or the specific path to the compiler.

Default

Linux: OFF

The host compilation will be performed by the Intel® DPC++ Compiler.

Windows: /Zc:__cplusplus

The host compilation will be performed by the Microsoft* __cplusplus preprocessor macro, which depends on the setting of option /std (or /Qstd). For more information about macro /Zc:__cplusplus, see the Microsoft documentation.

To override this default, specify option /fsycl-host-compiler-options=/Zc:cplusplus-.

Description

This option tells the compiler to use the specified compiler for the host compilation of the overall offloading compilation that is performed.

NOTE:

When using this option, you must also specify option -fsycl.

For information about available SYCL drivers, refer to Invoke the Compiler.

IDE Equivalent

Alternate Options

Example

Consider the following:

-fsycl-host-compiler=g++              // the compiler looks for g++ in the PATH
-fsycl-host-compiler=/usr/bin/g++     // the compiler looks for g++ in the explicit path
