How does GNU Make work?

Makefile. Make searches the current directory for the makefile to use, e.g. GNU Make searches files in order for a file named one of GNUmakefile, makefile, or Makefile and then runs the specified (or default) target(s) from (only) that file. The makefile language is similar to declarative programming.

What does makefile do in Linux?

Makefile is a program building tool which runs on Unix, Linux, and their flavors. It aids in simplifying building program executables that may need various modules. To determine how the modules need to be compiled or recompiled together, make takes the help of user-defined makefiles.

How does the make program in GNU work?

The make program uses the makefile data base and the last-modification times of the files to decide which of the files need to be updated. For each of those files, it issues the recipes recorded in the data base. You can provide command line arguments to make to control which files should be recompiled, or how.

Where does GNU make get its knowledge from?

Make gets its knowledge of how to build your program from a file called the makefile, which lists each of the non-source files and how to compute it from other files. When you write a program, you should write a makefile for it, so that it is possible to use Make to build and install the program.

What are some useful features of GNU make?

GNU Make also has a few simple features that are very convenient. For example, the -o file option which says “pretend that source file file has not changed, even though it has changed.” This is extremely useful when you add a new macro to a header file.
