# Makefile for my_program
CC = gcc
CFLAGS = -Wall -std=c11
all: my_program
my_program: major.c
$(CC) $(CFLAGS) major.c -o my_program
“`
This Makefile defines three variables: CC, CFLAGS, and all. The CC variable specifies the compiler to make use of, which on this case is gcc. The CFLAGS variable specifies the compiler flags to make use of, which on this case are -Wall (to allow all warnings) and -std=c11 (to make use of the C11 commonplace). The all variable specifies the goal of the Makefile, which on this case is the my_program executable file.

“`
my_program: major.c
$(CC) $(CFLAGS) major.c -o my_program
“`
This rule specifies that the my_program executable file is determined by the principle.c supply file. When the make command is run, it is going to first verify if the principle.c file has been modified for the reason that final time the my_program executable file was constructed. If the principle.c file has been modified, then the make command will execute the next command to rebuild the my_program executable file:
“`
$(CC) $(CFLAGS) major.c -o my_program
“`
The rule to wash up the construct listing is as follows:
“`
clear:
rm -rf my_program
“`
This rule specifies that the clear goal is determined by no different targets. When the make clear command is run, it is going to execute the next command to take away the my_program executable file from the construct listing:
“`
rm -rf my_program
“`
