=============== ocl_icd_wrapper

About

This project provides an OpenCL ICD wrapper for implementations that don't support the ICD extension. For example, Apple's OpenCL implementation currently doesn't support the ICD, which means an OpenCL application running on OS X has to be rebuilt when switching between Apple's OpenCL implementation and any third-party OpenCL implementations on the sytem. This project exposes such implementations to applications using the OpenCL ICD.

Usage

These instructions assume that you have a working OpenCL ICD on your system. The OpenCL ICD can be downloaded from the Khronos registry: http://www.khronos.org/registry/cl/

After configuring the build system, you should run 'make', and indicate the library you wish to wrap by specifying arguments to LDFLAGS. For example:

make LDFLAGS+="-framework OpenCL"

Copy the resulting library to your desired location and then register the library with the ICD. For example:

echo "libocl_icd_wrapper.dylib" >/etc/OpenCL/vendor/apple_wrapper.icd

You should ensure that this library is on the {DY}LD_LIBRARY_PATH, or alternatively use the full path to the library. You may wish to rename the library if you are planning to wrap more than one implementation.
