Can't load libgdx desktop app on mac osx

Question

I have been developing a simple game using libgdx on my Windows 7 PC. Recently I bought a macbook pro (mountain lion). I downloaded and installed JRE 7 and eclipse, then cloned and imported the project. However though there are no errors in the code when I run the desktop version I the JVM loads and quickly dies. The error I get in the console is as follows:

JavaVM WARNING: JAWT_GetAWT must be called after loading a JVM
_NSJVMLoadLibrary: NSAddLibrary failed for /libjawt.dylib
JavaVM FATAL: lookup of function JAWT_GetAWT failed. Exit
AL lib: ReleaseALC: 1 device not closed

I've added JRE 7 to the build path libraries, still no joy.

The desktop launches through this code:

import com.badlogic.gdx.backends.lwjgl.LwjglApplication;
import com.badlogic.gdx.backends.lwjgl.LwjglApplicationConfiguration;

public class Main {
    public static void main(String[] args) {
        LwjglApplicationConfiguration cfg = new LwjglApplicationConfiguration();
        cfg.title = "colourgame";
        cfg.useGL20 = false;
        cfg.width = 480;
        cfg.height = 800;

        new LwjglApplication(new ColourGame(), cfg);
    }
}

Really stuck on this ladies and gents. Please get back to me! Thanks.

Answer 1

According to this http://lwjgl.org/forum/index.php/topic,4711.0.html problem is with compatibility of JRE 7 update 6 with Lwjgl.

Problem seems to be fixed in a newer release of the library. I'm not sure if libgdx is updaetd accordingly but you can try to put the new version in your libs folder.

This problem got sorted with the latest nightly build from libgdx, after doing this I got stucked into another problem, the method IntersectRectangles was missing in that release.. So i had to go back to the latest stable version and got that working, but... the problem mentioned above appeared again. So I´m going to stick to the latest stable version so I can deploy on my android device with the code working...

So temporal solution: to test while you develop use the nightly build, if you don't need the method above all should be fine(I wonder if there are more methods missing I didn´t have to use..)

If you still need to use a stable or old release of libgdx. You might want to try to install jdk 1.6 (which I have done) in addition to jdk 1.7.

1. Download JDK1.6
Use this question to download jdk 1.6: jdk 6 on mountain lion

2. Add JRE home
In eclipse, go to preferences -> Java -> Installed JRE's and add jdk 1.6's home (just as your 1.7 version should be).

3. Set run configuration to use 1.6
Go to Run -> Run configurations -> YOUR CONFIGURATION -> JRE. Select 1.6 as the alternative JRE. :)
