OpenGL

[mariodpr]

Hi,

I'm trying to execute codeswarn with OpenGL support without success.

- I read the RunOpenGL wiki page.
- UseOpenGL=true in sample.config
- export LD_LIBRARY_PATH=path-to-codeswarm/lib

If I try to execute run.sh:
----------------------------------------------------------------------------------------
Error while running applet.
java.lang.RuntimeException: You need to use "Import Library" to add
processing.opengl.PGraphicsOpenGL to your sketch.

I try all these things:
- Add ${lib}/gluegen-rt.jar to build.xml
- Add lib/gluegen-rt.jar to run.sh
- Add import processing.opengl.*; to src/code_swarm.java

Any advice on what to do?

Regards,
Mario

It's not really helpful for you, but the reason you get different
errors between run.sh and 'ant run' is because of a bug in run.sh -
not all of the jars in lib/ are included in the classpath.

See this patch:

As far as debugging your problem, could you give:

* the contents of your codeswarm/lib directory
* your platform
* and your java version?
