I implement a link list in two files in linklist.h and linklist.c, and I call some functions defined in linklist.h in main function of main.c. linklist.h is included in both linklist.c and main.c. When I compile this program by GCC with Makefile, the error named "undefined reference to xxx" occurs. I think my Makefile is written correctly as below. So what is the possible reason for this linking error

CC=gcc

CFLAGS= -g -O2

TARGET=target

OBJECTS=main.o linklist.o

TARGET: $(OBJECTS)

 $(CC) $(CFLAGS) $(OBJECTS) -o $(TARGET)

clean:

 rm target $(OBJECTS)

main.o:linklist.h

linklist.o:linklist.h
