Hi friends. I recently bought firepro v5900 and “clBuildProgram (-11)” error occurs when I turn OpenCl on. I installed the latest driver and also checked my card by GPU-Z software. It says that my card supports OpenCl. I found a post about reinstalling Houdini with new simple path but after reinstalling my problem was not solved. I am using free version of houdini. maybe free version of houdini does not support openCl??? but my gtx 260 graphic card had no problem with openCl simulation. Would you please tell me how can I use opencl with my new VGA??? Thank you very much…
