Blending problem (GL's could not be resolved)

Hi everyone,

I am just starting my journey with cocos2dx. I have a problem with using ccBlendFunc
I noticed that when i try to use, any GL_ things like GL_ZERO etc. couldn’t be resolved.

I am almost sure that this is some kind of problem with importing, but I couldn’t fix it by myself.

I am using windows 8,android, eclipse, cocos2d-x-2.2.1, android-ndk-r9c
