I'm trying to run Image application from server "bert"

I connected through my OSX Maverick as 

ssh [email protected]

I compiled my file with 

$ make

but when I run the resulting file

$ ./window

it gives me the following error:

Error: Unable to initialize gtk, is DISPLAY set properly?

How can I solve this problem?

You should connect with the -X or -Y option to be able to launch graphical applications:

ssh -X [email protected]

If that doesn't help, you should consult /etc/ssh/sshd_config whether X11Forwarding is enabled.
