Well … gcc is a compiler, make is a tool to help build programs. The difference is huge. You can never build a program purely using make; it’s not a compiler. What make does it introduce a separate file of “rules”, that describes how to go from source code to finished program. It then interprets this file, figures out what needs to be compiled, and calls gcc for you. This is very useful for larger projects, with hundreds or thousands of source code files, and to keep track of things like compiler options, include paths, and so on.
