If you want to reload a library dynamically, you can use dlopen function (see mans). It opens a library .so file and returns a void* pointer to it, then you can get a pointer to any function/variable of your library with dlsym.

To compile your libraries in-memory, well, the best thing I think you can do is creating memory filesystem as described here.
