You need to point java to the jogl.so

java -Djava.library.path=/location/of/jogl.so Gears.


EDIT: It's actually libjogl.so not jogl.so my bad.

Hi.

some Linux tipps:

• No need to include the ext directory in $PATH or $CLASSPATH.
  
• your native library must be called libjogl.so
  
• the directory where libjogl.so lies needs to be listed in java.library.path
  

You can also set the environment  variable LD_LIBRARY_PATH to include the directory where your shared library is located. The dynamic linker will look for this variable and include the shared libs found there.

Thanks guys, finally I could run Gears.java in linux! Is a good graphics card really needed for jogl to work in Linux properly??

I tried porting my application over to linux but faced the following error which was non-existence in windows xp

An unexpected exception has been detected in native code outside the VM.

I used a GLCanvas, placing it in a JFrame

1   2   3   4   5   6   7   8   9   10   11

final Container c = getContentPane(); c.setLayout(new BorderLayout()); glc = GLDrawableFactory.getFactory().createGLCanvas(cap); glc.setSize(640,480); glc.requestFocus(); glc.addGLEventListener(view); // Add the Component into the window c.add( "Center", glc ); pack(); show();

I believe this is because a problem with mixing heavyweight components (GLCanvas) and lightweight (JFrame).

It should work if you change to either using a Frame with GLCanvas or using GLJCanvas (?name?) with a JFrame.

Probably something like

1	GLDrawableFactory.getFactory().createGLJCanvas(cap);
