unit testing: Xcode Units Tests can't find header file

mercredi 27 janvier 2016

I'm using Xcode Unit Tests which import a file that tries to import the OpenGL headers like this:

#import <OpenGL/gl.h>
#import <OpenGL/glu.h>
#import <OpenGL/glext.h>

Unfortunately, it can't find these files. If I try to import them in the Unit Test files directly they are also not found.

In my actual app (both for iOS and Mac OS), everything works fine.

I've probably read all posts here and tried everything I found on Google, but no luck yet. Also full clean, rebuild, restart, etc. does not work.

I hope somebody has an idea.
