From 3c19f0165f8ef508a92bf1266c16ed4bbb75c204 Mon Sep 17 00:00:00 2001 From: Chuck Atkins Date: Fri, 15 Apr 2016 11:05:21 -0400 Subject: [PATCH] glx: Refactor the configure options for glx implementation choice Instead of cascading support for various different implementations of GLX, all three options are now specified through the --enable-glx option: --enable-glx=dri : Enable the DRI-based GLX --enable-glx=xlib : Enable the classic Xlib-based GLX --enable-glx=gallium-xlib : Enable the gallium Xlib-based GLX --enable-glx[=yes] : Defaults to dri if DRI is enabled, else gallium-xlib if gallium is enabled, else xlib This removes the --enable-xlib-glx option and fixes a bug in which both the classic xlib-glx and gallium xlib-glx implementations were getting built causing different versioned and conflicting libGL libraries to be installed.
