    SimpleGL error with CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR

    allenlorenz

      Machine A3850 fusion, running ubuntu 10.10 64 bit.  After intalling catalys, SDK, and building the samples, I get the following error when running SimpleGL

      Error: clCreateContextFromType failed. Error code : CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR

      any suggestions ?
