    warning: ignore unrecognized OpenCL extension cl_khr_fp64




      I'm working under Ubuntu 12.04 with AMD APP 2.7 on a Radeon 5870 and a Intel Core I7 860. Both devices support the cl_khr_fp64 extension according to the opencl extension query. But when I try to use:

      #pragma OPENCL EXTENSION cl_khr_fp64 : enable


      in my kernel I got the mentioned warning. cl_amd_fp64 works though. Whats wrong?
