about Makefile and Macro

Helllo,,, guys..

i'm kind of newbies for c++

here is my problem..

i'm now taking a CPSC course
and one of the lab that i'm doing is about Makefile

here is my Makefile

Code:

CC = gcc # Compiler CFLAGS = -D_POSIX_SOURCE=1 # Compiler flags ## OLD CFLaG ## -c -I./lib LFLAGS = # Linker flags LIBS = -L./usr/X/lib -lXaw -lXmu -lXt -lX11 -lsx # Library ## old ## LIBS = libsx.a # Library ## new SRCS = button.c colormap.c Dialog.c draw.c DrawingA.c font.c libsx.c list.c menu.c misc.c popups.c scrollbar.c string_entry.c toggle.c version.c PROG_OBJS = $(SRCS:.c:.o) # Object files PROG = courses # Executable name RM = /bin/rm -f # For cleaning $(PROG): $(PROG_OBJS) $(CC) $(LFLAGS) $(PROG_OBJS) $(LIBS) -o $(PROG) %.o : %.c $(CC) -c $(CFLAGS) $< -o $@ .SUFFIXES: .c .c.o: $(CC) $(CFLAGS) -c $< clean: rm -f $(PROG_OBJS) $(PROG) *~ depend: makedepend -- $(CFLAGS) -- $(SRCS)

i'm now having a problem with
Define macro _POSIX_SOURCE with the string "1"

i am asked to define this macro with the value "1"
i then insert this

Code:

-D_POSIX_SOURCE=1

to my CFLAGS

i believe that everythign should be fine; however, i still receive this err
