undefined reference to `glLineWidth' on android~

cocos2d-x C++
1

my code worked fine on iPhone, but when i run ./build_native.sh, error occured:

./obj/local/armeabi/objs-debug/game_logic/Game2Scene.o: In function `BorderedSprite::draw()‘:
/Users/user/cocos2d-1.0.1-x-0.10.0/Puzzles/android/jni/…/…/Classes/Game2Scene.cpp:30: undefined reference to `glColor4ub’
/Users/user/cocos2d-1.0.1-x-0.10.0/Puzzles/android/jni/…/…/Classes/Game2Scene.cpp:31: undefined reference to `glLineWidth’

i think i missed some link lib in Android.mk, but i don’t know it’s name… could anyone tell me how to solve the error? thanks for any help~

You can refer cocos2dx/Android.mk, it invoke OpenGL functions.
You should link GLESv1_CM.
