OpenCLTM API C++ bindings

Doxgen documentation for the bindings is available here:

http://khronosgroup.github.io/OpenCL-CLHPP/

Components:

  • include/CL/opencl.hpp: The latest, maintained, version of the C++ bindings. It should work with all versions of OpenCL (including 1.x). This is what most users will want.

  • include/CL/cl2.hpp: Includes opencl.hpp and emits a warning, for backwards compability.

  • docs: Doxygen file used to generate HTML documentation for opencl.hpp.

  • examples: A simple example application using the very basic features of the bindings.

  • tests: A (very small, incomplete) set of regression tests. Building the tests requires Python, Ruby, Unity and CMock. For the last two we use Unity 2.1.0 and CMock top-of-tree from Github (the version 2.0.204 on Sourceforge does not work).

  • CMakeLists.txt: Build system for the examples and tests and logic for the bindings installation.

To get external dependencies needed for testing, use --recursive when cloning the repository, or run git submodule update --init --recursive.

You may need to tell CMake where to find the OpenCL headers and libraries, using the variables OPENCL_INCLUDE_DIR and OPENCL_LIB_DIR.

These can be set either as environment variables, or on the cmake command line using the syntax -D<VAR>=<VALUE>.

The following is an example set of commands to checkout and build the C++ bindings (adapt paths as required):

    git clone --recursive https://github.com/KhronosGroup/OpenCL-CLHPP
    cd OpenCL-CLHPP
    mkdir build
    cd build
    cmake .. -DOPENCL_INCLUDE_DIR=/path/to/OpenCL/headers -DOPENCL_LIB_DIR=/path/to/OpenCL/library
    make
    make test

After building, the headers appear in build/include/CL/.

If Doxygen is available, you can generate HTML documentation by typing make docs.
