Hello, I am trying to install pocl in Odroid-XU4 board. But After the installation when I am trying to run any opencl program I am getting segmentation fault. I am sharing the gdb error message -

Do I need to initialize something or build the pocl in a specific manner. It will be great help if you can give some insights on it. Thanks and regards, Srijeeta
