Description Krzysztof Klimonda 2010-12-08 23:59:05 UTC 
In the gtkglext/gtkmm/gl/widget.cc, the sequence of #include directives is important - if gtk/gtkglwidget.h is included before widget.h, it includes gdk.h without undefing GDK_DISABLE_DEPRECATED - this leads to GdkSpanFunc not being defined and compilation errors.
The fix is to first include widget.h which includes the right gdkmm header
which defines GDK_DISABLE_DEPRECATED before including gdk.h.

Attached is a (misnamed) patch that switches the sequence of includes in gtkglext/gtkmm/gl/widget.cc so it builds.
Comment 1 Emmanuele Bassi (:ebassi) 2014-11-09 22:45:06 UTC 
the GtkGLExt bindings are maintained outside the gtkglext repository, and both the bindings and the library are basically unmaintained.

GTK+ 3.16, released February 2015, will have OpenGL support out of the box, and the gtkmm bindings should be able to pick that up.
