When using the Program
constructor to auto-build a program, the header will pass the -cl-std=CL2.0
flag to the OpenCL compiler by default. This may be causing your crash, if you device only supports OpenCL 1.2.
You can make it so that the default is to build for OpenCL 1.2 instead by defining the CL_HPP_CL_1_2_DEFAULT_BUILD
macro before including cl2.hpp
.
from opencl-clhpp.
@jrprice This does work to solve the issue, but in general, I'd rather not rely on preprocessor macros to enforce the correct behavior, not least of which because some of my devices actually are OpenCL 2.0 compatible (and it looks like the one that succeeded on both platforms is). Is there a way to implement this behavior in cl::Program::Program
itself, either by a user-passed flag, or by an internal check of the device's supported versions of OpenCL?
