int

main(int argc, char **argv)

{

  cl_device_id        device;

  cl_context          context;

  cl_command_queue    queue;

  int                 err;

  cl_device_type      device_type = CL_DEVICE_TYPE_GPU;

  cl_uint numPlatforms = 0;

  cl_uint devices = 1;

 

 

  cl_platform_id platforms;

 

 

  // Now, obtains a list of numPlatforms OpenCL platforms available

  // The list of platforms available will be returned in platforms

  clGetPlatformIDs(1, &platforms, &devices);

 

 

  err = clGetDeviceIDs(platforms, device_type, 1, &device, &devices);    //这一行碰到了崩溃

  if (err != CL_SUCCESS) {

  printf("clGetDeviceIDs() failed. (%d)\n", err);

  return EXIT_FAILURE;

  }
