This might be stupid question, but have you installed
or only nvidia-libopencl1 when compiling PyOpenCL with NVIDIA library?
The Nvidia driver in debian experimental (I know it means something is
broken...) has no nvidia-opencl-dev in it. It does not provide the
include-headers files for OpenCL.
I included the header from opencl-headers version 1.1
(1.1-2010.07.15-2). I found them in the archives of Ubuntu as Debian
ships only headers for version 1.2 :(
Do I answer your question ?
