error: 'int32' does not name a type


I want to use ofxTuioWrapper with Box2d.
I’m getting this error when I compile [using xCode].
ofxTuioWrapper/core/TuioClient.h:192: error: ‘int32’ does not name a type

I was not able to find a clean way to solve this.
It works if I change - int32 currentFrame; by int currentFrame; - in TuioClient.h (line 192) but I would like to avoid this, and learn how to deal with this.
