Hi,
This is my first post on OF, also I don't have any C++ experience so my answer can be wrong. Anyway....
In every example folder there's an addons.make file, it contains the addons needed for the project:
- ofxCv
- ofxFaceTracker
- ofxGui
- ofxOpenCv
Create a new empty project using the Project Generator, in the addon section check all the addons required by the project (the ones listed in addons.make file). After you generate the project, copy the src folder from the example, on top of the generated src folder. Then open the project in CodeBlocks and you should be able to run it.
Hope that helps....
Alecule
