ERROR: clGetDeviceInfo() -30

[atom]

Thanks for the hint, but oclHashcat uses size_t.

Here is a quote from the headers:

void hc_clGetDeviceInfo (cl_device_id device, cl_device_info param_name, size_t param_value_size, void *param_value, size_t *param_value_size_ret);

So I would say he is using an old driver version which did not use size_t?
