Hey Nate,
just grabbed the new run times and i getting errors in my IDE.
I noticed in
MixTest.java you are referring to

import com.badlogic.gdx.backends.jglfw.JglfwApplication;
import com.badlogic.gdx.backends.jglfw.JglfwApplicationConfiguration;

So i pulled the new LibGDX Nightly's and added
gdx-backend-jglfw-natives.jar
and
gdx-backend-jglfw.jar to my project but now get this error:
libjglfw64.so: undefined symbol: clock_gettime
Im using OpenJDK 1.7.0 for the project.

Any idea's or am I missing a lib jar? I even validated I wasn't missing any thing by passing the LibGDX setup Gui over it with a update on the project.. but still this one error

Thanks!

I got it working again when i switch all the settings back to Lwjgl .. im guessing jglfw might not be 100% linux compatible.

I have moved this to the Github issue tracker rather then the forums. Thanks!
