We got an build issue of a tizen app which depends on our latest efl source.
It looks, efl_canvas_object.eo doesn't properly specify api reference under the eo rule.
The error message is here:
eolian: efl_canvas_object.eo:467:35: failed validating reference 'Evas.Canvas.key_modifier_add'
Please take a look efl_canvas_object.eo for resolving above one.
