Thread: make all rule

I need to add a "all" rule to my make file, but ive never seen what that is before, and ive done a search but cant find anything. the all rule is meant to make it so that make all produces an executable.

Can anyone please show me. heres the makefile that i have already made:

Code:

CC=gcc
OBJS=num.o
EXTRA-FLAGS=

num: $(OBJS)
	$(CC) $(EXTRA_FLAGS) -c num.c
clean:
	rm -f num ${OBJS}
debug:
	make EXTRA_FLAGS=-g
tar:
	tar cf num.tar makefile num.c
