[gl4java-usergroup] can't install or compile gl4java on Fedora Core 2

[Tamara M. <tm...@cs...>]

Hi all you GL4Java loyalists,

I'm trying to get gl4java to work on a recent version of Linux. I
bitterly regret upgrading my Linux laptop, since it all worked OK on
the old version. I'm now running Fedore Core 2, the 2.6.9 kernel. I
really really really want to be able to run my software again on my
laptop. I'm running into the same error that I've seen several posts
about:

 An unexpected exception has been detected in native code outside the VM.
 Unexpected Signal : 11 occurred at PC=0xEF1
 Function=[Unknown.]
 Library=(N/A)
 [....]

I can post the thread and library dump if that would be helpful, but I
strongly suspect it's the same known problem as all the others - an
OpenGL driver problem. I've seen several postings attributing this to
nVidia drivers, but I'm not using an nVidia driver. It's an ATI Radeon
Mobility 9000 card, and I'm running the following OpenGL version:

% rpm -qif /usr/X11R6/lib/libGL.so.1.2
Name        : xorg-x11-Mesa-libGL          
Source RPM: xorg-x11-6.7.0-2.src.rpm

I noticed that in 2003 Ken answered several questions with "switch to
jogl, gl4java isn't being supported". Even if I wanted to port our
codebase (which I don't right now), I really need control over the
graphics context in a way that as far as I can tell jogl doesn't
support (i.e. I need glMakeCurrent).

I also saw some postings saying that even if the binary installation
doesn't work there's a workaround in the CVS library. So I tried
compiling the latest version of gl4java by checking it out of the
repository like this:

 cvs -z3 -d:pserver:ano...@cv...:/cvsroot/gl4java co GL4Java

When I set up the Makefile to use jdk1.4, then the compile in the
directory GL4Java/GL4Java dies on the following error:

 gl4java/awt/GLOffScreenDrawable.java:75:
 gl4java.awt.GLOffScreenDrawable is not abstract and does not override
 abstract method removeKeyListener(java.awt.event. KeyListener) in
 gl4java.drawable.GLDrawable
 public class GLOffScreenDrawable

I then noticed that the Makefile seems pretty insistent on also having
java1.3 available, so I installed that too. In that case I get 100
compile errors instead of just one, so that wasn't really progress.
Same place, GL4Java/GL4Java

Any ideas would be immensely appreciated.
