OK, so I read somewhere that there seemed to be an issue with Xamarin's GtkSharp installation interfering with GtkD's operation, however I have removed the GTK_BASEPATH variable from my environment variables list, and ensure nothing else exists on the path but the 3.8.1 32-bit Gtk+ installation from the home page of this website, and I still get
The procedure entry point gdk_pixbuf_animation_new_from_resource could not be located in the dynamic link library libgdk_pi9xbuf-2.0-0.dll
Now, the strange part is that I can copy that dll file from a Gtk+ 3.6.4 distribution I found into the Gtk+ bin folder and that error goes away, but then a different entry point error for libgdk-3-0.dll comes up instead, and the 3.6.4 version of that file doesn't fix it. I don't want to uninstall Xamarin, but it seems to run on GtkSharp, so I can't get rid of the files.
Is there ANYTHING I can do?
