Need help to link static gtk

[Günther Rapp <guenther rapp-informatik de>]

Linking my application with shared lib's all is ok but
trying to set  -static option the following undefined references occur

/usr/lib/libgdk.a(gdkinput.o): In function `gdk_input_device_new':
gdkinput.o(.text+0x68e): undefined reference to `XOpenDevice'
/usr/lib/libgdk.a(gdkinput.o): In function
`gdk_input_common_select_events':
gdkinput.o(.text+0xbcf): undefined reference to `XSelectExtensionEvent'
/usr/lib/libgdk.a(gdkinput.o): In function `gdk_input_common_init':

gdkinput.o(.text+0xd20): undefined reference to `XFreeDeviceList'

/usr/lib/libgdk.a(gdkinput.o): In function
`gdk_input_xfree_ungrab_pointer':
gdkinput.o(.text+0x1f43): undefined reference to `XUngrabDevice'

The linking options are
GTK_LIBS = -L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -rdynamic -lgmodule
-lglib -ldl -lXext -lX11 -lm
What lib is missing?

The system is rh7.2
