Linux Makefile: Compile Four Files Simultaneously

This Makefile will compile four files (file1.c, file2.c, file3.c, file4.c) and create a program from them. The 'all' target is set as the default target and it depends on the 'program' target. The 'program' target depends on the four object files and will be compiled with the gcc command. The four object files will be created using the gcc -c command. The 'clean' target will remove all object files and the program.

.PHONY: all

all: program

program: file1.o file2.o file3.o file4.o gcc -o program file1.o file2.o file3.o file4.o

file1.o: file1.c gcc -c file1.c

file2.o: file2.c gcc -c file2.c

file3.o: file3.c gcc -c file3.c

file4.o: file4.c gcc -c file4.c

clean: rm -f *.o program
