Ok, so while doing some research for automated building from a solution/workspace/etc, I've managed to compile a VC++2008 Solution file using VCBUILD. Not too complicated. Is there anything that simple for VC++6? I can't seem to find it as easily in the docs, and since I already got it working in 2008, my drive to dig for it hasn't been that great, but if someone already knows about it, it'd be very useful to me. I'll probably look again right now, I just don't want to if someone else here already knows. Also, similar info for XCode would be nice, or any other info on compiling FS2 from say, a Perl script on OS X and/or Linux. I'm assuming Linux should be the easiest since it's already set up for a command line compile. I know nothing about compiling it on OS X though.
Edit: Ok, it looks like the closest thing to that is using nmake. So, I exported .mak files for each of the 5 projects I care about in the workspace, but running nmake on them fails, the code project won't compile via this method currently. Something missing or some such. I probably just need to tweak some stuff, but if anyone can get FS2 to compile with VC6's nmake, I'd love to know how you did it. I'm usually just winging it through these things.
