क्यों जब मैं अपने makefile के साथ अपने कार्यक्रम संकलन मैं प्राप्त है कि:फ़ाइल समस्या बनाओ?

मेरे makefile यह है:
CC=gcc
LD=gcc
C_FLAGS= -Wall -pedantic

RWK=_wk
#Liste des dossier dans lesquels effectuer la recherche ordonnee
DIRS= \

लेकिन जब मैं इस तरह एक साधारण makefile के साथ और के साथ कोई फ़ोल्डर शामिल किए जाने की कोशिश मैं 'कोई त्रुटि किया है:
CC=gcc
LD=gcc
BIN = hello
SRCS=$(wildcard *.c)
OBJS = $(SRCS:.c=.o)
DEPS = $(SRCS:.c=.d)
CFLAGS = -W -Wall -pedantic
