c - gcc: "No such file or directory"

Question

I have received an error when i launched "make"

I didn't know where is the problem.

I guess in the makefile. Can you help me !Thanks :)

CC := gcc
CFLAGS := -Wall -Werror -g
LDFLAGS :=
LIBS := -L. -lamqp
SRCS := amqp_consommateur.c amqp_producteur.c

OBJS := $(SRCS:c=o)
PROGS := $(SRCS:.c=)

.PHONY: all
all: $(PROGS)
    @echo "$(MAKE) : Tout est généré"

$(PROGS) : % : %.o Makefile 
    $(CC) $< -o $@ 

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

clean:
    rm -f $(PROGS) $(OBJS)
