I am really new to the GPU programming. I just set up my Nvidia driver and installed everything about cuda.
so you can assume that I installed every thing necessary.
I downloaded examples provided online, for example: nbody. I tried to compile it by typing make.
It doesn’t compile, it shows the following:error:
must #include before using typeid
so, i tried added the line #include to the files that don’t compile, then, i tried to compile it again, I get the following errors:
Why do I get these errors? Is it because i didn’t set up the environment correctly?
