There are lots of error to compile OpenCL sample: DirectX with OpenCL, DXVA with OpenCL, .etc. Almost any samples with Windows related will not compiled in VS 2012 Express. I think there may have some include errors because of the upgrade from VS 2010 project to VS2012. Should Intel provide VS 2012 project files as well? I have found auto upgrad errors in my own programs.
BTW Shall I install Media SDK to compile these samples downloaded from Intel's OpenCL sample site?
