A makefile is a file that results from using the "make" processing tool, a tool used in software development to build a program in its final ".exe" file extension form together with its libraries. The make tool performs an interpretation process of make files to determine the final code of the destination .exe file.
Topological sorting is used to define the point at which "make" should start. Make is the most commonly used method among program-building systems and is typically used with Unix-based program building.
Make has many more applications than just .exe program building from source files. Some of these applications include:
This system's advantages include that it works on building up a file dependency list, which allows it to be used in a general manner for many file conversion applications. Make’s disadvantages include the fact that if a certain dependency is forgotten, it will not be discovered immediately, but will appear later. Make allows more potential for human error.
