ERROR: Could not create window, root cause: ''

Hi guys,

I just finished installing Urho3D on RPi 3.
Now after reboot, I receive the following errors:

[code]root@raspberrypi:/home/pi/Urho3D/bin# . Urho3DPlayer

bash: .: Urho3DPlayer: cannot execute binary file

root@raspberrypi:/home/pi/Urho3D/bin# . NinjaSnowWar.sh

I don’t know whether the problem is GPU / OpenGL or not. Because both glxgears and NeverPutt (it’s a game) are working fine in my RPi. So I’m pretty sure I’ve installed graphics correctly.

So, what is the problem !!?
How can I solve this !!?

I have enabled the experimental OpenGL driver or RPi through raspi-config.
Could this be the reason of this error !?

I reinstalled Raspbian Jessie OS.
Then reinstalled Urho3D (experimental OpenGL disabled, and GPU=768 MB.)

Now after cmake and make, when I run ./Urho3DPlayer , it gives the following:

Now what should I do !!?
