Qt GUI example won't compile
-
I just installed Qt 5 and have never used Qt before. If I try to create a Qt GUI application, it will not compile the basic code that is already provided to me. Without altering the code at all, I received an error saying:
@10:32:15: Running steps for project FirstGUI...

The error message is that libGL is not found. Have you installed it and its development package?

Awesome, thank you. I got it working by installing the libgl1-mesa-dev package on synaptic. I think I had some form of libGL but one without developer files. Sweeeet.
