Thanks.

There is not as much for Fortran, but I think that by now I've learnt most of the Fortran-specific stuff. I will keep reading through the docs. As you said, it is a bit overwhelming at first. >> There is no "add_object" function or anything like it... Maybe I am >> going about it the wrong way.

I think I will try to come up with logical groupings that can be turned into libraries. > Converting incrementally can't be done IMO (at least not without significant > overhead).

I don't mean that I expect to compile the entire program with a half-Makefile, half-CMake system. I like your idea of making libraries. If I can make a library with a handful of files and I can verify that the compile didn't fail and the library has the correct symbols, I would call that a successful incremental step. > I hope that cleared up some of the confusion.
