OpenCL support on Leopard

I want to use OpenCL in my software but I am running Leopard.

I will probably update to Snow Leopard later. In the mean time I would like to get started with OpenCL in Leopard. Setting up on 10.5 is confusing: most SDKs and articles assume that you must be using Snow Leopard. Searching for "Using OpenCL on Leopard" is completely useless, as you would expect.

I downloaded the cuda toolkit, devdriver and gpucomputing SDK from nvidia but the examples won't compile because OpenCL/opencl.h is not found. The OpenCL release notes don't mention MacOSX so again I think this is assuming that all Mac users are running Snow Leopard.

Where can I find OpenCL includes and libraries for Mac OSX 10.5 ? Or, is this just a waste of time and I should go and get Snow Leopard ASAP ?

After upgrading to Snow Leopard I would like my software to support Leopard. Is this possible ?

I believe the headers necessary to compile OpenCL code are included with the Nvidia GPU Computing SDK (path is something like NVIDIA_GPU_Computing_SDK/OpenCL/common/inc/CL). You could copy or link these into the directory where your compiler looks for includes (/usr/include/CL/ on Linux, not sure for Mac). Alternatively, you could get the headers from khronos.org/registry/cl. The libraries themselves should be included with either the SDK or the cuda toolkit (I don't recall which).

You will need to upgrade to Snow Leopard. Also note that OpenCL really isn't ready for "prime time" software development on any platform yet. CUDA is much more mature than OpenCL and you should consider using CUDA rather than OpenCL if you want to develop and deploy GPGPU-dependent software in the near future.
