Built On: 2020-09-02
Version: 1.0.0


This extension is written against the OpenCL Specification Version 3.0.3.

This extension requires OpenCL 3.0 with OpenCL C 2.0 support or OpenCL 2.x and cl_khr_extended_versioning.


This extension adds support for building programs written using the C++ for OpenCL kernel language. It also enables applications to query the version of the language supported by the device compiler.

New build option

This extension adds support for a new CLC++ value to be passed to the -cl-std build option accepted by clBuildProgram and clCompileProgram.

New API Enums

Accepted value for the param_name parameter to clGetDeviceInfo:


Modifications to the OpenCL API Specification

(Modify Section 4.2, Querying Devices)
(Add the following to Table 4.3, Device Queries)
cl_device_info Return Type Description



Returns the version of the C++ for OpenCL language supported by the device compiler.

(Modify Section 5.8.1, Creating Program Objects)

Add the following text to the description for clCreateProgramWithSource:

The source code specified by strings may also be a C++ for OpenCL program source or header.

(Modify section to 5.8.6, Compiler Options)
(Add subsection, C++ for OpenCL)

Applications may pass -cl-std=CLC++ to clCompileProgram and clBuildProgram for programs created using clCreateProgramFromSource to request the program be built as C++ for OpenCL.

Conformance tests

  1. Test that a program can successfully be compiled with -cl-std=CLC++.

  2. Test with a program compiled with -cl-std=CLC++ that the value of the __OPENCL_CPP_VERSION__ macro agrees with the version returned by CL_DEVICE_CXX_FOR_OPENCL_NUMERIC_VERSION_EXT.
