introduce make and its description file makefile in detail. Makefile The most important and basic function of the Make tool is to use the makefile file to describe the relationship between source programs and automatically maintain the compilation work. The makefile file needs to be compiled according to a certain syntax. The file must describe how to compile each source file and generate an executable file, and define the dependency between the sour
