In the link I posted, the guys say lwjgl has already been ported to GL ES and is available to download in the Ubuntu 10.10 Armel repository, did you try that.

Also thanks for trying this, as not many people seem to care for a good game running on their devices.

This is strange. My attempts have presented me with an error message from lwjgl requesting for the file "libxxf86vm.so.1".

That is one of the depencies, libxxf86vm. It's installable.
But next up it looks for libGL.so, which is exclusive to desktop GPUs. The N900 doesn't have support for OpenGL, only GLES. That's the reason why we can't run it with precompiled libraries from Ubuntu. (Ubuntu only has OpenGL unless you pull in some TI drivers, but they're barely supported. So, sorry to say: Ubuntu only supplies a few components. We need to compile LWJGL with ES support ourselves.
I've been attempting to compile it, but it fails when I get to doing "ant compile_native_es".
This is the output:

Code:

(I'm compiling it in my on-device SDK)
Beside the source, it is suggested to remove AWT, but I'm not a Java expert. Do we have any Java programmers aboard?

But it seems like there are no Java programmers around to examine the error report?

Looks like an OpenGL issue. I'm not a Java expert though.

Oh, forgot to look at your post. My bad, looks like you already know that.

Well, I've looked over where the errors occur. It's not in GLES (which is good

)
But it's in OpenCL and OpenGL. (We don't really need the latter... But it's a part of it anyway.)
I might start looking around for a pre-compiled one, as we have no progress with compiling it.

Ok... new info on the case:
http://www.khronos.org/news/press/re...l-4-1-released
http://lwjgl.org/forum/index.php/top....msg18888.html
If you read both of these thorougly, you'll be thinking the exact thing I'm thinking.
But it's barely anything. It's more of a desperate solution...

Do you think the open pandora's compiled files will be good enough?

It depends. If you're talking about Angstrom, then yes, if it doesn't depend on anything funny.
And if it's compiled for the Cortex-A8, definitively.
Have you found binaries for the Pandora that are compiled with GLES?

The Open Pandora uses the omap 3530 which is the exact same hardware as the N900, but the CPU is just clocked at a higher rate, (but we can OC too) so yeah, it would be compiled for the A8.

I just can't seem to find the thread I've found a thread referring to it, but not the actual one that may help.
Another, the user "spasi" is the one we're looking for.

There's always the option of Minetest...
