</div>Shader support is not platform dependent.<br>
<br>
As you've found, geomtry shaders aren't supported. See:<br>

I'm sure it's on someone's radar for future work, but I would guess<br>
that nobody's actively working on geometry shader support.<br></blockquote><div><br>Doesn't the Gallium3D software driver support geometry shaders on Linux?<br><br>See this article:<br>A 30,000 Line Patch For Mesa Brings Geometry Shaders (Sept 2009)<br>

However, this new support is considered "basically working" (bugs may be aplenty) and the only driver<br>
implementing this geometry shading support is the Gallium3D software driver."<br><br><br></div></div>
