OpenCL driver issue with Samsung Chromebook


I had an issue with the OpenCL Driver on my Chomebook.

I followed ARM's instruction and successfully boot into Linux. However, I got an error message said that missing. After install libxcb-dri2.0-dev, I can compile Mali OpenCL SDK sample codes. But they won't be executed correctly under X11 or via fbdev. I past error message below. Any suggestion? Thanks.
