I'm assuming you are using Raspbian Jessie.
I don't remember having to do anything special on my Pi that required
privileged access (besides cranking up the amount of GPU memory). But
I have a pretty boring Pi setup. (Just the basic with a HDMI into a
TV. No cameras or touch screen, etc.)
Does my demo program work for you?
Run the ./FlappyBlurrrC
Everything should be self-contained. I ship my own copy of SDL with it.
