Created attachment 591098 [details] xorg-server-1.20.5:20190925-222544.log With libglvnd-provided pkgconfig files: $ pkg-config --modversion gl 1.2 Upstream bug report: https://gitlab.freedesktop.org/xorg/xserver/issues/893
Fixed by commit 5a6deca6e403ca195b255bf78d41a5da4819d617 Author: Matt Turner <mattst88@gentoo.org> Date: Wed Sep 25 14:50:06 2019 -0700 x11-base/xorg-server: Allow building against libglvnd Mesa's gl.pc contains a version that matches the Mesa version, but libglvnd's gl.pc version is the SO version (1.2). The Xserver checks for gl >= 7.1.0 and gl >= 9.2.0 which are very old versions of Mesa at this point, so removing the version dependency doesn't negatively affect anything and allows the Xserver to build against libglvnd.
