Hello. As you can see, I'm new here, so I'm probably breaking some rule, but oh well. I have read pa very good tutorial in c, and I decide to try it. I already know GML, which is very similar to c. I think it actually turn the GML to c++ before compiling it, but that's beside the point. Anyways, I downloaded Xcode, (I have snow leopard by the way), and I went back to the start of the tut, and it said to run the default code to make sure it works, and I did, but the words hello world didn't appear. As a matter a fact, nothing much happened at all. A bar popped up for a moment, not long enough to read, then it said it had compiled successfully, but the running window didn't pop up. I think it has something to do the the pound include at the to ( which is there) but I don't know what. Please help, I'm really excited to try it out. And, I know there are some other #include things for the start, what are some that I should include, and what's the bool one again? Thsnkyou.
