Hi all i'm trying to test the camera example after installling the userland and raspicam libraries by following this link : https://github.com/robidouille/robido...

when typing startx , i open another terminal and i type ./raspicamtest but i get the message : : cannot connect to X server plz help thanks :)

i'm using ubuntu 14.04 with opencv 3.0.0

How are you invoking ./raspicamtest ? If you're invoking it over ssh connection, you may need to enable X11 forwarding in your ssh connection. You can't invoke a GUI application over simple SSH connection.

If you're having a linux box, use "ssh -X ..". If using putty, there is a seperate option for X11 forwarding. You will have to enable it from there. Hope it helps.
