I'm an indie game developer. I haven't shipped anything because I have too much passion for core technology issues. I hope to use advanced programming languages to gain a business advantage. I'm also into 3D graphics, AI, assembly language optimization, and build systems. I have spent so much time trying to get open source software to work on Windows, that I have become a build systems expert! :-)
I wrote 95% of the CMake build system for Chicken. CMake does all the things GNU Autoconf does, but in a truly cross-platform manner. For instance it will generate native MS Visual Studio files, whereas Autoconf - by the design and intent of its authors - will never, ever play well with MSVC. Actually MinGW is my primary development environment, and much of the project was fixing Chicken on MinGW. My goal was to get the build support on Windows to be first class, reliable, reproducible, and painless to use. Eventually we want this to be true on every platform. Once the CMake build has proven itself for awhile, we'll be getting rid of the GNU Autoconf build, which almost nobody likes.
