[Mesa-users] Geometry Shader support in Mesa i965 DRI for Intel SandyBridge Hardware

[yusuf husainy]

Hello all,

I am trying to run the GS demo code of Mesa from here :
http://cgit.freedesktop.org/mesa/demos/tree/src/gs, by git cloning this:
http://cgit.freedesktop.org/mesa/demos

However, I get the error as "needs GL_ARB_geometry_shader4 extension".

I am not that up to date with how the Mesa development is going on, but it
seems that GL_ARB_geometry_shader4 extension is not available for Mesa?

As per this link:
http://lists.freedesktop.org/archives/mesa-dev/2014-August/065692.html, it
shows Geometry Shader support has been added to Intel SandyBridge platform.

I also came across this link:
http://dri.freedesktop.org/wiki/MissingFunctionality/, which indicates that
the GL_ARB_geometry_shader4 extension is a "Missing Functionality".

Considering all of this, how should I proceed to write my applications with
geometry shaders using Mesa?

if any other information is required, please do let me know.

I appreciate any help. :)
