Error when kernel function calls another function

[tamas-ferenci]

Consider the following - very silly, but illustrative - example:

 float sqrplusone( float in )
 {
   return in*in+1;
 }

 __kernel void SAXPY(__global float* x, __global float* y, float a)
 {
   const int i = get_global_id(0);
   y [i] += a * sqrplusone(x[i]);
 }

This is the content of saxpy.cl; let's now try to compile it:

  cl_args <- setup_opencl(objects = c("vclVector", "vclVector", "scalar"),
  intents = c("IN", "OUT", "IN"),
  queues = list("SAXPY", "SAXPY", "SAXPY"),
  kernel_maps = c("x", "y", "a"))
  custom_opencl("saxpy.cl", cl_args, "float")

This gives the following error message:

Error in custom_opencl("saxpy.cl", cl_args, "float") : 
   Non OpenCL buffer kernel arguments don't match to initialized objects.
