Purpose of a make file:

fdfd

Multiple purposes:

fdfd

How does make know which files to compile?

make stores the timestamp of files and checks if files have been modified after their timestamps. If so, their respective commands are executed. If not, nothing is executed for the file.

MyPorject: main.o module1.o module2.o
     gcc -o MyProject main.c module1.c module2.c


main.o: main.h module1.h
    	gcc -c main.c


module1.o: module1.h String.h module2.h
    	gcc -c module1.c


module2.o: module2.h String.h
    	gcc -c module2.c

	
archive: 
    	tar -cvf *.c *.h String.o MyPorject.tzg


clean:
    	mv String.o String.tmp
    	rm *.o
    	mv String.tmp String.o
