Error: Gtk+ cross compiled

[albrecht ellinger <albrecht ellinger dold-regler de>]

Hello,

I successfully compiled the gtk+ libraries and dependencies for mips.
__________
configure:

  $ CC="/opt/emlix/netdcu6/bin/mipsel-linux-gcc -g -fPIC" ./configure
--prefix=/home/albrecht.ellinger/gtkTest --cache-file=mipsel.cache
--host=mipsel-linux --build=i686-pc-linux-gnu --without-libtiff
--with-gdktarget=linux-fb --without-x --without-libjpeg

______
Error:

# ./simple

Error opening /dev/psaux: No such file or directory
 
(simple:926): Gdk-WARNING **: Mouse driver open failed
 
(simple:926): Gdk-WARNING **: Failed to initialize mouse
 
(simple:926): Gtk-WARNING **: cannot open display:

I have touch screen so I do not worry about mouse driver.
But the screen is blank (or rather black).

Framebuffer works ( /dev/fb0 manufacturer samples work)

I suspect DirectFB is not working correctly (Testprogram fails).
However, I configured gtk+ for linux-fb. So I think I do not really need
DirectFB?

Has somebody had the same error? 

Greetings

Albrecht
