cannot load library to the device 0 (error code 5)

hi， I recently met a error while using Xeon Phi. When the program run into the #pragma offload area, it occur error “offload error: cannot load library to the device 0 (error code 5)” and then exit. I wonder what the "error code 5" mean? Can anyone provide me the error code list of the offload error? I can not find such thing through the Internet. Thanks
