Make file 생성시의 궁금점

gnu make 를 공부 중입니다.

폴더에, stack.cpp stack.h stackTest.h

이렇게 세개의 파일이 있구요 , 스택.h와cpp 는 스택에 대한 구현을 ,
테스트는 , cxxTEST를 이용한 테스트를 담고 있습니다

이클립스가 아닌 , makefile 을 이용하려 하는데 자꾸 에러가 납니다.
어더가 잘못 되었는지요?러

CPP=g++
OBJECTS = Stack.o
CXX_DIR = ../cxxtest
CXX = $(CXX_DIR)/cxxtestgen.pl
CFLAGS= -Wall -g -ftest-coverage -fprofile-arcs
TEST =  Stacktest.h
 
.SUFFIXES : .o .cpp .c
 
.cpp.o :
	$(CPP) $(CFLAGS) -c $<
 
all: Stack
 
Stack: $(OBJECTS)
	$(CPP) $(CFLAGS) -o Stack  $(OBJECTS)
 
Stack.o: Stack.cpp
	$(CPP) $(CFLAGS) -c Stack.cpp Stack.h
 
#Run the unit tests
run_tests: runner
	./runner
# Generate the test runner
runner.cpp: $(TEST)
	$(CXX) --error-printer $(TEST) -o runner.cpp
 
 
test-coverage:run_tests
	gcov -b Stack.cpp
 
 
clean:
	 rm -f runner* *.o *.gcov *.gcda *.gcno

이렇게 makefile 을 작성해 보았습니다.

터미널 창에서 make 를 치면 ,
다음과 같은 error 메세지가 나타나네요

g++ -Wall -g -ftest-coverage -fprofile-arcs -c Stack.cpp Stack.h
