OpenCL^TM SDK (in development)

This is the Khronos OpenCL SDK. It brings together all the components needed to develop OpenCL applications:

• OpenCL Headers (external/OpenCL-Headers/)
• OpenCL C++ bindings (external/OpenCL-CLHPP/include)
• OpenCL Loader (external/OpenCL-ICD-Loader)
• OpenCL utility library (lib/include)

It also contains resources useful to OpenCL developers:

• Code samples (samples/)
• Documentation (docs/)

Build Instructions

Dependencies

• This repository uses sub-modules for the OpenCL Headers, OpenCL C++ bindings, and OpenCL ICD Loader and some of their transitive dependencies.

  • To clone a new repository with all sub-modules included, use the --recursive option. Note that this option clones all sub-modules and their dependencies, which are not strictly required for the OpenCL SDK:

    git clone --recursive https://github.com/KhronosGroup/OpenCL-SDK.git

  • Alternatively, to clone only the sub-modules for the OpenCL SDK, first clone this repository without sub-modules included then setup submodules non-recursively:

    git clone https://github.com/KhronosGroup/OpenCL-SDK.git
    git submodule init
    git submodule update

• The SDK uses CMake for its build system. If CMake is not provided by your build system or OS package manager, please consult the CMake website.

• The SDK samples depend on

  • Templatized C++ Command Line Parser Library (aka. TCLAP)
  • Simple and Fast Multimedia Library (aka. SFML)
  • OpenGL Mathematics (aka. GLM)

Example Build

In most cases, the following steps may be used to build the OpenCL SDK.

1. Clone this repo and update submodules:

    git clone https://github.com/KhronosGroup/OpenCL-SDK.git
    git submodule init
    git submodule update

2. Create a “build” directory:

    mkdir build
    cd build

3. Generate build files inside of the “build” directory:

    cmake .. -DCMAKE_BUILD_TYPE=Release

4. Build the OpenCL SDK and copy files to an “install” directory:

    cmake --build . --target install --config Release

   Or, build the OpenCL SDK using the generated build files directly.

To customize a build, the following CMake variables are supported. To specify one of these variables via the command line generator, use the CMake syntax -D<variable>=<value>. See your CMake documentation for more details.

Variable	Type	Description
CMAKE_BUILD_TYPE	STRING	Specifies the build type. Does not affect multi-configuration generators, such as Visual Studio solution files.
CMAKE_INSTALL_PREFIX	PATH	Install directory prefix.
OPENCL_SDK_BUILD_UTILITY_LIBRARIES	BOOL	Enables building OpenCL SDK utility libraries. Default: TRUE
OPENCL_SDK_BUILD_SAMPLES	BOOL	Enables building OpenCL SDK samples. Default: TRUE
OPENCL_SDK_BUILD_OPENGL_SAMPLES	BOOL	Enables building OpenCL SDK samples that interoperate with OpenGL. Default: FALSE
OPENCL_SDK_BUILD_VULKAN_SAMPLES	BOOL	Enables building OpenCL SDK samples that interoperate with Vulkan. Default: FALSE
OPENCL_SDK_TEST_SAMPLES	BOOL	Enables a target to test the OpenCL SDK samples. Default: TRUE
