Can't build against GTK 3.16.x or later

[tumagonx]

Since GTK 3.16, gtkglarea was built-in and have conflict with GdkGLExt at least for its gdkglcontext.h file and GdkGLContext namespace. Can we still use GdkGLExt?

Check my fork https://github.com/Pan7/gtkglext
Fixed the conflicts.

@Pan7 unfortunetly your fork doesn't compile for me too.

Anybody has a solution?

after bootstrap and configure I come up with the following error:

In the gdk folder:
No rule to make target 'gdkglcontext.h', needed by 'gdkglenumtypes.h'. Stop.

There is a file called: gdkglcontextimpl.h

?
