[Buildroot] [RFC 3/4] opengl-registry: Also provide DRI interface

Jérôme Pouiller jezz at sysmic.org
Wed Jan 21 11:23:27 UTC 2015


xserver need dri_interface.h. This file is normally provided by mesa3d.
In order to compiler xserver with another libgl provider, we need to
provide this file somewhere. For simplicity, we choose to place it in
opengl-registry package even if file does not come from Khronos.
