From #855:

I would be curious what your environment looks like for building DwarfCorp on Mac, and I would be happy to update our documentation with instructions for how to do this. If it's just a matter of building content on windows then a development environment on Mac/Linux might be possible with prepackaged content.

I've put my makefile into my branch mono-build (diff).

The approach uses the libraries and content from the Steam release to build and run against. I did this mainly to avoid having to build libraries and having to fully reverse engineer the VC build. As-is, the approach is only reliable for building code changes based on the same release tag of the Steam release used as a basis.

The approach could be extended to build a full app bundle and take libraries from somewhere else than a release bundle, actually building those libraries that need to be built. If there is interest in doing that, I can look into it. I'd very likely need pre-built content, but I haven't looked into that yet.
