hi Arick, > I get this error: reference to undefined identifier:ffgl-load are you sure you have installed fluxus from the latest git source after compiling? ffgl-load should be included. what does (help "ffgl") return? you can also check this: nm /opt/local/lib/fluxus-016/compiled/native/i386-macosx/3m/fluxus-engine_ss.dylib | grep ffgl_load best, gabor
