Using GCC as a compiler isn't too alien to me as I've used Dev-C++ for a while. The IDEs that you can get for Linux aren't as nice as say Visual C++ (or even Dev-C++ for that matter) but to be honest I'll get used to it. One IDE that is really shininy out is MonoDevelop, the C#/MonoBasic (think VB) .NET IDE and compiler.
I'm going to attempt a configuration of Apache soon and try and get Mono (or some form of ASP) running from there. Wish me luck ;)
I successfully compiled Manta-X with GCC today. It took me a couple of hours hunting down my non-standards compliant code (fortunately not too much). I have SiCrane to thank for one ellusive section that's fairly critical to the game as a whole :)
In all - I'm enjoying a shiny new OS and all it's strangeness - There's something kinda cool about compiling your own software too [grin]
