This line looks very suspicious for me:

<unknown>:0:0: in function vexcl_vector_kernel void (i64, double addrspace(1)*, double, double addrspace(1)*): unsupported call to function get_global_id

Are you able to compile and run any OpenCL program on this platform? Here is a link to a minimal example using raw C++ API: https://gist.github.com/ddemidov/2925717.
