Suffices to perform all necessary recompilations. Once a suitable makefile exists, each time you change some source files, this simple shell command: In a program, typically, the executable file is updated from object files, which are in turn made by compiling source files. To prepare to use make, you must write a file called the makefile that describes the relationships among files in your program and provides commands for updating each file. You can use it to describe any task where some files must be updated automatically from others whenever the others change. Our examples show C programs, since they are most common, but you can use make with any programming language whose compiler can be run with a shell command. GNU make conforms to section 6.2 of IEEE Standard 1003.2-1992 (POSIX.2). Development since Version 3.76 has been handled by Paul D. This manual describes GNU make, which was implemented by Richard Stallman and Roland McGrath. The make utility automatically determines which pieces of a large program need to be recompiled, and issues commands to recompile them. Index of Functions, Variables, & Directives.
