Beginning to program on BeOS/Haiku - Part 3

I'm now into Chapter 9 and should finish the book up in the next week or so. I've located the zip file from the book's web site and even compiled a few of the examples from the early chapters. Some worked and others didn't. Once I finish the book I'll be going back and checking over the examples and see if I can figure out why they didn't just work. I suspect it's my folder setup. I think I need to make sure I have everything in the correct places first.
