glGetFramebufferAttachmentParameter missing in libGL.so.1

[mdjurfeldt]

I run a linux guest in a Windows 10 host.

In the guest, the OpenGL function glGetFramebufferAttachmentParameter is missing in /usr/lib/virtualbox/additions/libGL.so.1

Due to this, I get linker errors in many packages and can't enable 3D acceleration.

Is this something you can support? What is the status on this?

[mdjurfeldt]

I guess this is due to VirtualBox currently only supporting OpenGL up to 2.1 while the function I ask for is OpenGL 3.0.

First question: what does this break. Second question: can you provide a patch?
