I search a lot for the answer above. All the methods were proposed for Linux. The mingw-gcc 64-bit indeed supports the openACC. I can call the runtime API of openACC in the qtcreator.
However, when I call:
acc_get_device_num(acc_device_nvidia);
or
acc_get_device_num(acc_device_not_host);
the libgomp say: no device found.
Or, is there ways to offload using mingw64 in MSYS2 Pacman in Win7?
