Try projected shadows, they look almost the same and don't require this extension.

if that look the same , why Shadow Mapping in "Shadow" menu choice?
and how to get "GL_ARB_shadow_ambient" extension?

thanks for the reply and the linux port.

Shadow maps are better, they provide shadows on everything, not just the terrain. And I find very weird that your video card doesn't support this extension, maybe is because of the Linux drivers, because my GeForceFX supported it in Windows.

What version of OpenGL does yout driver support? Maybe your card supports it but not as an extension and I should make some changes to the game code. (You can check that in the api-info section of glest main menu)
