[gtkmm] Problems with Gst::Object

[Christian Meyer <chrisime uni de>]

Hi!

I'm currently trying to wrap Gstreamer. My main problem is Gst::Object.
I'm quite unsure if the ctor is correct. IMO I need a wrapper which
transforms a Glib::Object to a Gst::Object.

Second problem:
It seems like the compiler doesn't like my defined macro or the macro
used in GstObject (see
http://gstreamer.net/docs/0.4.0/gstreamer/gstobject.html for more
information)

Any help, suggestions, rants, improvements are highly appreciated.
I'm so damn stuck.

Thanks in advance.

Greetings,
Christian
