Fixing problems when compiling programs
Most of us in science learn to write and build computer program in an ad-hoc way, copying bits of Makefile from other people, and using trial and error to change things.
That's fine when everything works, but when stuff starts to go wrong it's useful to have an idea of what different steps are happening during compilation, so you can figure out what's going wrong. In this post I'll talk at a a fairly high level about what happens when you compile code, and in a bit more detail about fixing problems you might see when you doing so.
