Which one, gtk2 or gtk3 did you use? I tried both of them worked.
There were very few feedbacks on jgtk/opengl and I have only one
linux box to test, therefore I really don't know what was wrong in
your situation. If you can show how you got the gl context using
libx11.so then it might be easie
To add a bit of information:
I tried a Radeon HD2400 card in place of the GeForce 8600 in my 64-bit
Linux system. This time the system did not even get a chance to announce
that it could not obtain a context, it crashed J(gtk) and closed all its
windows as soon as the demo OpenGL program was run.
Sorry, don't think I can help at the moment, I link against freeglut when I
write in C, however I'll keep an eye out for code that accesses the
x.orgNVidia driver directly (when I figure out how it's all plumbed).

The hardest part should be getting the opengl context, after that it
should be fairly standard in all platforms.
If there will some simple opengl demo source codes in plain C that can
work with GeForce, then we may try to translate that into J.

You may be on the money with that one. I was unable to get GL working on a
Linux 64 with a Geforce card in spite of considerable effort.

That seems to narrow the problem down to Nvidia GeForce cards on 64-bit
hardware.

I'll keep you posted on anything else I notice.

Hi All (especially Bill)
Some of you may remember that a few days ago I wrote describing the
problems I was having, trying to get OpenGL (both 701 and 602) to run on my
Linux system.
Well, I had the opportunity to try it on a number of systems, and on the
basis of what I saw, I am now pretty sure
Well, I edited all the options you suggested, Bill, and also the occurrence
in the file glx.ijs, with every possible combination, and nothing worked.
Damn.
Oh, well, back to C++ for now then (bleah!) where at least OpenGL works.
Hope I sort it out sometime soon, I'd much rather be working in J.
Th
Not sure which lib was selected. You may edit the file
~addons/api/gl3/gl3.ijs and change the lines
libgl=: 'libGL.so.1'
libglu=: 'libGLU.so.1'
to (eg)
libglu=: '/usr/lib/libGLU.so.1'
I have not installed any proprietary video driver to test, so there
may be some issues there.

My system is Ubuntu Lucid 64 (LTS)
I installed all J addons via pacman, right from the start!
When I try to run something like:
load '~addons/demos/opengl/simple/gldemos.ijs' or
load '~addons/demos/opengl/demo/gldemo.ijs'
the GTK windows open properly, but nothing is rendered, the message

I tested opengl (both 32 and 64-bits) worked in my debian. The
context is provided by x11. Perhaps some addons such as api/x11 are
missing. Install that addon and try again. If it still fails, then
install all addons. You can always un-install addons in pacman.

Decided to try 701, I had been putting it off...
Quite nice, I found, the gtk ide seems OK, I also updated all the pacman
stuff.
I like it, I might carry on with it (I was a bit wary of anything new, my J
is not that strong anyway)
Guess what? Still no joy on the OpenGL front.
It says "OpenGL OK"
The libGL and libGLU provided by mesa are fine although you should
most probably already using libGL/libGLU provided by the nvidia
driver. The problem is related to OSMesa (off-screen mesa), I
suppose the libOSMesa6 is new enough and using libOSMesa7 won't help.

Thanks for that Bill
I got the latest (*.64) base library and de-installed the freeglut stuff.

/usr/lib/libOSMesa.so

/usr/lib/libOSMesa.so.6.5.3
So that seems fine.
It is still not working though.
The "opengl simple" demos open blank b
the j602 install from jsoftware.com is the oldest, the current
verson is 64. pacman is the package manager in the menu of the ijx
window. You should update it first. After that, I guess you can
un-install freeglut dev and it can still work.

You must use a very old version of J602 base library, please update

The opengl (or simple opengl?) demo requires osmesa in linux j602,

Right OK, a bit of an update:
I additionally installed the freeglut dev kit, and the first reported

Now the dialog box with the 'Demos' opens, and what's more, most of the
demos seem to run OK.
However, there is still a problem with the OpenGL ones:

That should be the only use of find_dll not yet fixed. Please
try in bash shell,
$ locate libOSMesa.so
and report what will be the output. (should be something like

I did not install osmesa so not sure if nvdia opengl driver will
conflict with osmesa or not.

Hi - I thought I might try some OpenGL cookery on my Linux (Ubuntu)
system, but I have no luck as it is currently set up.
If I try anything involving OpenGL, eg. the 'Demos' I get the following
