Hi, i am creating a scrollview in cocos2d-x v2.0.4 & i’m using this extension: [[https://github.com/cocos2d/cocos2d-x-extensions/tree/master/extensions/CCScrollLayer]], but the problem is that when i try to build application the build fails and gives me errors like:
Use of undeclared identifier ‘GL_POINT_SMOOTH’
Unknown type name CCFloat
Any one help me please 
GL_POINT_SMOOTH is deprecated in OpenGLEs2. I guess you are trying to display the page bullets in CCScrollLayer::visit(). You can comment out glEnable(GL_POINT_SMOOTH), but you will get squared bullets instead. To get the nice round solid shape bullets, I had to modify the CCDrawingPrimitives.cpp and add a function called ccDrawSolidCircle(). This function is the exact copy of ccDrawCircle(), simply replace ‘GL_LINE_STRIP’ with ‘GL_TRIANGLE_FAN’ in glDrawArrays() call.
If you are developing for android and iOS make sure you also update the CCDrawingPrimitives.cpp in cocos2d-x library and ./build_native.sh
Hope it helps,
