clpp

Lightweight and easy to use the OpenCL C++ wrapper in single file. This library supports:

  • UNIX, Linux, Windows environment
  • C++, C++11 language standard
  • error handling by C++ exceptions
  • OpenCL 1.0, 1.1, 1.2, 2.0, 2.1 and 2.2 (not fully tested)
  • OpenCL-OpenGL interoperability

Installation

Just copy 'clpp.h' file to your '/usr/include' or '/usr/local/include' (just this is single file!).

Build samples and tests

Make a building directory, run cmake and make:

mkdir build
cd build
cmake ..      (or cmake .. -DBUILD_TESTS=ON for building tests)
make
ctest   (if tests enabled)

Some samples requires libpng library or SDL library. Tests requires SDL library.

Documentation

Run 'doxygen' in project directory. This will makes 'docs' directory that will contains documentation for library.

Important Defines and macros

clpp.h can use an OpenCL functions defined for specified version. Macro __CLPP_CL_ABI_VERSION defines from what version of OpenCL standard functions will be used by your program. For example you can use only OpenCL 1.1 functions and in case you define:

#define __CLPP_CL_ABI_VERSION 101   // 101 is version number
....
#include <clpp.h>

Likewise, __CLPP_CL_VERSION defines from what OpenCL standard version features will be used by clpp.

Other important macros are:

#define __CLPP_CL_EXT  // enables OpenCL extensions.
#define __CLPP_CL_GL   // enables OpenCL-OpenGL interoperability support.
#define __CLPP_CL_GL_EXT   // enables OpenCL-OpenGL interoperability extensions support.
