There is NO currently supported wiringPi source code download, at least
none by me, the author, so I've no idea where you're getting the source
from. If you're using Raspbian, then sudo apt-get install wiringpi,
however read this and pick another GPIO library

And remember; wiringPi is intended for experienced C and RTB BASIC
users only. It's not a newbie learning tool.
