If you could look and just make sure you included all the source files, that would be nice. AUA works fine in the RevDCM available for download, but if you try to build a core with the source code provided, the above error occurs - also the gamecore built is a few kilobytes smaller then the one that comes downloaded. I think we're just missing an altered source file. If Firaxis would just release the source code, I'd look at Civ5 and start working on something. But I'll be damned if I start working on hacky LUA mods. I want access to the damned objects themselves!
