[PD] GEM on raspberry pi

Sorry if this has already been answered, but is it possible to run GEM
on the raspberry pi?

I've just installed the Pd-0.43.3-extended-20121004.deb file from

So far so good, but when I try to open a gemwin the following error

"GEM: X server has no OpenGL GLX extension"

Googling for info I came across this:


GLX is an extension to the X windows server which allows GL programs to
pass their commands through to the underlying renderer. On the pi there
are two fundamental problems:

1) GLX is currently only designed to support OpenGL, not OpenGL ES. RPi
doesn't actually support OpenGL, just OpenGL ES (1.1 and 2.0).

2) The underlying xf86-video driver needs to support GLX. The default X
driver for the pi right now is the fbdev driver, which doesn't support
GLX. I don't know of any drivers that are working on GLX support, but
they'd have to provide some kind of translation mechanism as well to
convert unsupported GL calls into their GL ES equivalents.

For the foreseeable future, you're probably out of luck.


Is that the case? Is there no way of running GEM on the raspberry pi at
