I am trying to port GTK+DirectFB to the COWON O2. This PMP uses the DaVinci chipset with an embedded ARM9. My first go around was to assemble all of the necessary libraries and then build a GTK test app. I'd started to build a custom input driver but wanted to give the TSL and DirectFB defaults a go first. The micro-Linux running on the O2 has no support for shared objects so all the libraries and test app are build static.

When running my test app (see: http://wingtk.sourceforge.net/ishan/sliders.html), I was able to capture the following output:

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| DirectFB 1.3.0 |~~~~~~~~~~~~~~~~~~~
       (c) 2001-2008  The world wide DirectFB Open Source COmmunity
       (c) 2000-2004  Convergence (integrated media) GmbH
     ---------------------------------------------------------------

(*) DirectFB/Core: Single Application Core. (2009-02-09 06:50)
(!) DirectFB/core/system: No system found!
(#) DirectFBError [gdk_display_open: DirectFBCreate]: no (suitable) implementation found!

I am able to find in src/core/system.c -- dfb_system_lookup() where things go wrong but have not been able to determine why. Would appreciate any pointers.

Thanks,
Fred Beck
