From 2c4c912c15379ca26c976d2fdb27ff28ce546910 Mon Sep 17 00:00:00 2001 From: wm4 Date: Tue, 7 Jan 2014 01:06:28 +0100 Subject: [PATCH] wayland: silence annoying libwayland-client message libwayland-client contains the following code [1]: runtime_dir = getenv("XDG_RUNTIME_DIR"); if (!runtime_dir) { fprintf(stderr, "error: XDG_RUNTIME_DIR not set in the environment.\n"); This means this message will unconditionally and unavoidably be printed if XDG_RUNTIME_DIR is not set. Since mpv is a terminal program, and we want to avoid unnecessary output, work it around by not attempting to use wayland if this environment variable is not set.
