Sorry about that, I added those commented hint lines later, but used the error output from before. Buy it still gives me the same issue.

GLFW creates a context, and it looks like you're setting it as current. If that code does what it looks like, correctly, then the error especially wouldn't make sense. I would suggest to try validating the context, perhaps creating a debug context.

Can you point me to some resources that explain how I can do that?

It works if I simply set a single colour using `glClearColor()`. There is no crash, and it displays a window with the right color.

I did not think those ones were important. I assume it will use that latest version of opengl that I have. Is that not true?
