What is Makefile

A Makefile is a special file that is used to control the build process of a project. It contains a set of directives used by the make build automation tool to generate a target/goal.

Makefiles are commonly used in programming projects to specify how to compile and link the code, as well as to define dependencies between different files to ensure that the build process runs smoothly.

Here’s a basic example of what a Makefile might look like:

    CC=gcc
    CFLAGS=-I.

    all: myprogram

    myprogram: main.o functions.o
        $(CC) -o myprogram main.o functions.o

    main.o: main.c
        $(CC) $(CFLAGS) -c main.c

    functions.o: functions.c
        $(CC) $(CFLAGS) -c functions.c

    clean:
        rm -f *.o myprogram
