Linux: Unable to Execute Exported Sketches
Aug 19th, 2006, 4:28pm  
Hey,
I currently have a small sketch that I can use regularly with the processing "play" button. However, when I export it as an applet or an application, it crashes immediately on running.

The error the application gives in the console is:

Code:
Exception in thread "main" java.awt.AWTError: Cannot load AWT toolkit: gnu.java.awt.peer.gtk.GtkToolkit
   at java.awt.Toolkit.getDefaultToolkit(libgcj.so.7)
   at java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(libgcj.so.7)
   at processing.core.PApplet.main(PApplet.java:6019)
   at DECP1.main(DECP1.java:166)
Caused by: java.lang.ClassNotFoundException: gnu.java.awt.peer.gtk.GtkToolkit
   at java.lang.Class.forName(libgcj.so.7)
   at java.lang.Class.forName(libgcj.so.7)
   at java.awt.Toolkit.getDefaultToolkit(libgcj.so.7)
   ...3 more



Obviously this has something to do with how my JRE or libraries are setup. The question is, what exactly needs to be done?

Same problem here. I'm working on Linux...

Can anyone give a clue?

Thanks!

that looks like a version of gcj or some gnu java is being used to run things. try installing the runtime directly from sun (the rpm that's available from java.com) or check your distro for a more official version. the version of java included with processing is the one from sun, so if processing works, then that's the route to go.
