hi,
i’m using ofxDatGui with the multi-window application and i have errors when i declare the gui as a shared pointer in ofApp.h. i combined the multi-window example from oF and the data binding example from ofxDatGui. i receive a ‘no matching’ flag in ofmain.h and a ‘use of undeclared identifier’ flag for the shared pointer in ofapp.h.
