Well, I built it on Linux-x64 and it runs great. Really looks like a nice environment so far, for making 3D games ..
Then I tried to build it on my Pandora and got quite far, but alas there is a dependency in the MContext class, on glee.h, and associated gl* functions.
If we had a drop-in GL-like extensions class for GLES1.1 and GLES2 contexts, there's still quite a possibility that the tools in Maratis3d (editor, player, standalone-engine, etc) could actually run on the Pandora itself. The code for Maratis seems to be written with the expectation that a GLES1.1/2 context could be used, some time in the near future, for rendering .. meaning that it can switch between OpenGL, GLES1/2, for rendering .. 'easily'. There are comments to this effect in, for example, the MContext sources ..
But they're not quite there yet.
I will have another look at it soon though, because I think these guys have the goal of having their content creation system running quite smoothly on the ES profiles.
