Possible to set up, without a $100+ compiler?

[zigmoon]

Sorry, I can't find anything on if there's a compiler I can use that isn't $100+.

I did a few searches, but there have been no posts about other compilers that work. Now, I found a few threads talking about it, but they only really talked about the expensive ones. Are there any alternitives that I can use? I've been dying to set up a server, but only recently got a secondary computer that can run it.

Also, I'm really sorry if there have been posts about it, but I just needed to know if there were any free ones, or 'trial' ones that work well enough.
