My friend and I are working on a project together. A simple pong game. We wanted to figure out how to work with networking, and get a pong-over-the-internet-clone working.
I wrote a bunch of code, shows a background, some paddles, and a ball. Easy enough. We have a SVN set up, so when he gets home he gets a copy and follows the same steps I do to get the file compiled.
He runs it, none of the images are showing up. None of them. We have the exact same code, the exact same setup. Except his is 64bit windows 7, and I have 32bit windows xp.
The images show up fine on my machine (win xp), but they do not work on his (64bit windows 7). Anybody have any ideas? I think it might be a bug, but I have no idea in what. Especially since windows7 is brand new. I'll post my main.cpp file:
