How to set icon to the binary file created?

[enthudrives]

I have done a project. I dont want the binary file to be in the default diamond shape. I want it to be a jpg file instead.
How to do that?

In order to give you a quality response, can you please explain your question a little bit better?
Do you want to set a custom window or application icon?

You need to create and deploy a .desktop file for your application.
