No OpenGL 3.1 with Mesa 9.0?

I have Mesa 9.0 installed, and was very much looking forward to GL 3.1 support, but I don't seem to be able to use it? I have a i3-2330M sandybridge CPU, with intel integrated graphics.

Re: No OpenGL 3.1 with Mesa 9.0?

http://www.mesa3d.org/relnotes-9.0.html says

Mesa 9.0 implements the OpenGL 3.1 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don't support all the features required in OpenGL 3.1. OpenGL 3.1 is only available if requested at context creation because GL_ARB_compatibility is not supported.

so maybe that's why.

But, when I run windows, my driver goes up to GL 3.1, and I can run 3.1 programs just fine. I thought the intel driver was supposed to come with 3.1 support for mesa 9.0?

Have a look here, Their definition of OpenGL 3.1 support does not seem to fully extend to their linux end-users, that's how one might read that.

It also states there those "GL_ARB" compatibility features karol quotes are available in the windows driver. So, thats possibly why your question arises.
