undefined reference to `gdk_keymap_add_virtual_modifiers'

[IMS <ims77 dev gmail com>]

Hi,
I'm trying to compile my application for an embedded system using the last version of gtk (2.20.0) and direct-fb 1.4.3
I have a problem to compile with "gdk_keymap_add_virtual_modifiers" so I made a search and found a patch here : https://bugzilla.gnome.org/show_bug.cgi?id=605185
But I  still have a problem and don't know why ?
Follow some informations, thanks for any help ! 
One more info, I had no problems to compile with gtk 2.16.6 (but need to update the version to correct some bugs)


The error message :
