I’ve got a compiling issue with Kinect Draw 3D (source here: https://github.com/memo/ofxKinect-demos). I have Open Frameworks and OFXKinect working perfectly, so the problem is with the code (or missing files) for Kinect Draw 3D itself.
Well, ofSetHexColor is a new function in the unreleased next version of OpenFrameworks, so I would guess that the code you are compiling isn’t compatible with the current release version of OF?
So I guess (I dont know! you would either have to download the latest version of OF from github: https://github.com/openframeworks/openFrameworks
though that version might be unstable.
Or you might be able to downgrade the code the requires ofSetHexColor (it seems to be ofxSimpleGuiToo?) to an older version that is compatible with the OF version you currently have installed.
