First compile gives errors

[shellback3]

I've downloaded and installed Qt on Ubuntu 14.04. I followed a tutorial, created a project with a window with a label and text input. On the first (and subsequent) build I get an error: "Cannot find IGL"

What do I do now?

Hi and welcome to devnet,

Please take the time to search the forum a bit. This question has been asked and answered many times already (even again in the last 7 days).

You are missing the OpenGL dev libraries.

apt-get install libgl1-mesa-dev
