Yeah, that worked.
Everything compiles and the gears demo runs properly.

Very odd problem.  Hard to figure out why antlr.jar won't work when it resides in jre/lib/ext.  Doubly confusing, since the "class not found" error is for a jogl class, not an antlr class.  Perhaps the antlr code is reading the CLASSPATH and trying to locate itself for some reason.

Thanks very much for your help.

My apologies if this has been addressed before or the answer is in a FAQ somewhere...

I'm having difficulty building JOGL under both Linux and Windows.

Here is where the make process fails:

----

Not sure what the problem is here.
The class "net.java.games.gluegen.cgram.CToken" appears to have been compiled properly and is on the specified classpath:

----
peccary:~/is_knott/jogl/jogl/make> ls ../build/classes/net/java/games/gluegen/cgram/
......
CToken.class
......

Anybody have an idea what's gone wrong?

thanks,
