rel 8.1 for bootstrap build

[packages/qt5-qtbase.git] / egl-x11.patch

From f42186815187be1a0c5c0f9d6acc657872d3d533 Mon Sep 17 00:00:00 2001
From: Laszlo Agocs <laszlo.agocs@qt.io>

Subject: [PATCH] Cater for upstream changes in eglplatform.h

EGL_NO_X11 has been replaced with USE_X11, thus breaking all existing
code out there, including Qt:
https://github.com/KhronosGroup/EGL-Registry/pull/130

Fix this by defining USE_X11 whenever we do not define EGL_NO_X11.

Fixes: QTBUG-96392
Pick-to: 6.2
Change-Id: If8b68caa8c9022477d87169ca2e2a0121a9313e0
