Note that there is a good chance that will not happen; or, maybe, we'll write a state tracker for Gallium3d to emulate the Warp3D API; no idea yet.
There is a chance that there maybe will not warp3d support at all for new radeons hd , not directly (what is expected) , not even via gallium-emulation (i was expect that it will be 100% done, without maybe) ? Because imho not give new users with RadeonsHD warp3d/minigl support in any form, will not give them possibility to run many games, demos and apps. I.e. they will have opengl, but will not able to run any opengl stuff from os4depot , will sound a bit bad imho.
Anyway, you're missing SDL and OpenGL obviously, so this isn't related to MiniGL. The program you are trying to run probably requires them.
On aos4 opengl = minigl, and when he have words "cant initi opengl" in any game or app, it mean minigl all the time of course. You know it for sure that everyone who make some ports for opengl, use only minigl on aos4

Just some apps / games write "opengl" words, but its only text, in reality its all minigl based of course.
@Nicsoft
All the games which you try on your link based on opengl (minigl in our case), and they all want it (Even if you will install SDL, you will have no luck). I.e.: Aquaria, Cube, Neverball, SuperTuxKart, Celestia - the all want opengl (minigl). Only GianasReturn maybe will works (as it not want opengl(minigl) ), just some shared SDL libs (all of which you can found on os4depot.net).
