Hi.

I'm trying to get a P3D Processing sketch running on the Raspberry Pi and, having done quite a bit of research, it seems that I need to use JOGL for this, but, having followed Xerxes Ranby's instructions, I'm merely getting a transparent Processing window and the errors below.

I am using the 32 bit linux version of Processing.
Java -version is 1.7.0-40

Looking in core/library, gluegen-rt-android-natives-linux-armv6hf.jar is missing, but the following similarly named files are present:

gluegen-rt-natives-android-armv6.jar
gluegen-rt-natives-linux-armv6.jar
gluegen-rt-natives-linux-armv6hf.jar

I also have a question regarding NEWT, as I have read that I need to force Processing to use NEWT as opposed to AWT. Does JOGL take care of this or is there more that I need to do here?

I'm brand new to JOGL and by no means a programmer, so any guidance greatly appreciated. I hope that I have provided sufficient information for you to understand my problem.

Thanks,

B.

A library relies on native code that's not available.
Or only works properly when the sketch is run as a 64-bit  application.
