Please, change $ISE_LIBRARY\library\gobo\gobo.ecf into $ISE_LIBRARY\library\gobo\gobo_all.ecf in the file F:\Projects\Eiffel\traffic\traffic_ev_1079\example\02_objects\objects.ecf BTW, since you are trying to compile projects prepared for an older version of EiffelStudio with a newer one, be ready to get more errors and warnings.
