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

---

Something like:

Code:

---

EXEC=myprog.exe
all: ${EXEC}

${EXEC}: ${OBJS}
    $(CC) $(CFLAGS) ${LARGS} -o $(EXEC) $(OBJS)

---

Some additional help

Im getting a warning that newline is not the last character in the makefile, but there is a blank line there, so whats the problem.? Does it have to be a \n
?

A blank line isn't necessarily a newline (\n). Make sure the last character is a newline.

Now I get this:

make: Fatal error in reader: makefile, line 20: Unexpected end of line seen

What am i doing wrong??!!!

Code:

---

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

all: ${EXEC}

${EXEC}: ${OBJS}
        $(CC) $(CFLAGS) $(LARGS) -o ${EXEC} ${OBJS}

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
\n

You don't put \n in your file, just hit the [enter] button to create an empty last line.

Hmm well it must be the tester then, coz i tried that aswell :-)

Thanks for your help tho.

How do i get my program to end when the enter button is hit, with no input on the line?


Example:

$12345 (enter)
$24234 (enter)
$ (enter)
(program ends here.)

??

anyone? its urgent

if you're using fgets(), do it like so:

Code:

---

fgets(buf, sizeof buf, stdin);
if (buf[0] == '\n')
{
  Terminate
}
