I’m using ndk-r7 in Lion.

EDIT: Solverd with ndk r5b

#2

Oh, ndk-r7 has been released.
I haven’t tested with it.

#3

Since GL_GLEXT_PROTOTYPES was defined in glplatform.h in previous revision NDK,
In r7, GL_GLEXT_PROTOTYPES was removed from glplatform.h.
So simply add ~~DGL_GLEXT_PROTOTYPES=1 in cocos2dx/Android.mk, like:
LOCAL_CFLAGS :=~~DUSE_FILE32API -DGL_GLEXT_PROTOTYPES=1

and everything should work well.

#4

Thank you, Splash, that helped.

Hi guys,

I came across the same problem on NDK r9. Is this fixed in the beta release?

Here’s my patch that did the trick for me:
