Hi,
I'm trying NewtCanvasSWT inside an Eclipse ViewPart. I'm on Mac OS X 10.9.1
I've Jogl 2.1.3 plugin made following Wade's tutorial (+ the addition of Require-Bundle: org.eclipse.swt)

I'm still facing the fact that no context can be obtained with the following code

public void createPartControl(Composite parent) {

GLProfile glprofile = GLProfile.getDefault();
GLCapabilities caps = new GLCapabilities(glprofile);
GLWindow glWindow1 = GLWindow.create(caps);
               
composite = new Composite( parent, SWT.NONE );
composite.setLayout( new FillLayout() );

glcanvas = new NewtCanvasSWT( composite, SWT.NO_BACKGROUND, glWindow1 );
           
GLDrawableFactory gldf = GLDrawableFactory.getFactory( glprofile );
glcontext = gldf.createExternalGLContext();


last line fails with


SWTAccessor.<init>: GTK Version: 0.0.0

I have no clue on what's going on?! any help will be appreciated
