Hi ,

I have written the below Makefile .

srcdir   = ./lib
o        = .o

LDFLAGS  =
CC       = gcc
CFLAGS   = -O2 -Wall -Wno-implicit
INCLUDES = -I. -I$(srcdir)

COMPILE  = $(CC) $(INCLUDES) $(CFLAGS)
LINK     = $(CC) -o $@ $(CFLAGS) $(LDFLAGS)

RM       = rm -f

OBJ      = read_conf$o config_affairs$o getpass$o utilities$o        \
des$o md4$o http_header$o ntlm_procs$o ntlm_message$o     \
ntlm_auth$o base64$o basic_auth$o sig_hand$o              \
proxy_client$o server$o main$o

all: myaps

.o.c:     $(CC) $(CFLAGS) $(INCLUDES) -c $<

myaps: $(OBJ)       gcc $(CFLAGS) -o $@ $(OBJ)

.PHONY: clean

clean:      $(RM) *.o

After do make -n i get

gcc -O2 -Wall -Wno-implicit   -c -o read_conf.o read_conf.c
gcc -O2 -Wall -Wno-implicit   -c -o config_affairs.o config_affairs.c

gcc -O2 -Wall -Wno-implicit   -c -o main.o main.c
make: *** No rule to make target `gcc', needed by `myaps'.  Stop.

I do not find the reason why i get the message -" No rule to make
target `gcc', needed by `myaps'.  Stop." with my Makefile .

Can anyone help me with this problem

This should be on two different lines.

Besides the other reply you got, this line is somewhat dangerous:
it gives "make" a rule to convert a ".o" file into a ".c" file.
You want the opposite -- a method of converting a ".c" file into
a ".o" file.

Luckily for you, that rule is built-in, and reads, in effect:

.c.o:
$(CC) $(CFLAGS) -c $<

(note that this is two separate lines).  You will not get your
$(INCLUDES) expanded, since it is not part of $(CC) nor $(CFLAGS)
(but if you put your -I directives into CFLAGS, you will not need
your own rule anyway).

Hi chris ,

Thanks for your reply .

i first did try to put both on saperate lines . e.g.

.c.o: lib/aps.h
$(CC) $(CFLAGS) $(INCLUDES) -c $<

But to this line i get an error -

*** missing separator.  Stop.   How do i solve this error .

You need a tab character

>       $(CC) $(CFLAGS) $(INCLUDES) -c $<
^^^^^^^
here at the very start of the line instead a number of spaces.

Make sure you use a tab character, not spaces before the $(CC).
