+ (Class)layerClass won't work

问题:

I'm building an OpenGL application and on eaglview.m + (Class)layerClass wont work.

If i try to run it I get:

"Undefined symbols for architecture i386:   "_OBJC_CLASS_$_CAEAGLLayer", referenced from:       objc-class-ref in GLView.o ld: symbol(s) not found for architecture i386 collect2: ld returned 1 exit status" 

How can I fix this?

回答1:

You need to add the OpenGL and potentially the QuartzCore frameworks to the target to link them.
