Re: <gstmm.h> include errors

Hey José,

Sorry for getting back so late.

As for the problem with instantiating an element, i'm not sure where
the actual problem lies; the code for doing that is very simple, and
unless there is a reference counting problem it should just work;
could you try whether creating an element the C way on your box in the
same program works? E.g.

GstElement * element = gst_element_factory_make("filesrc", NULL);
