Hi,
Two main things to understand about make...
-
it's all based around dependancies
-
those dependancies all center around the date of a file.
If you have hello.c and want to build it, then create a "Makefile" as follows...
all: hello
hello.o: hello.c
$(CC) $(CFLAGS) -c hello.c -o $@
hello: hello.o
$(CC) $(CFLAGS) hello.o -o $@
The macros CC and CFLAGS are standard macros for your C compiler.
$@ means the target for the rule
So it will say, I want to make "all", so I want to make "hello", that depends on "hello.o" and here are the rules. Ah, I need hello.o first, and there are the rules to make that.
