The error that I get is:
Build on :

/tmp/OCLWr29ew.cl(45): error: mixed vector-scalar operation not allowed unless
          up-convertable(scalar-type=>vector-element-type)
     nonce = base + get_global_id(0) + (uint2)(0, 0x80000000U);
                                       ^

1 error detected in the compilation of "/tmp/OCLWr29ew.cl".


Any idea how I can fix this?
