> It looks like You have cross compiled eglfs plugin for framebuffer by
including EGL/eglvivante.h in freescale device eglfs hook. It's Ok!
The problem is that your libraries (EGL, GLESv2) are not framebuffer based.
Try
ln -ls /usr/lib/libEGL* /usr/lib/libGLESv2* /usr/lib/libGAL*

they should be symbolic links pointing to something like:
libEGL-fb.so, libGAL-fb.so and so on.
But I suppose they aren't. If they point to e.g. *-x11 then you system is X
based and you should build and use Qt xcb plugin.
