From 2bf3b37303b099e5e904c278eabba6d64053ac29 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Thu, 10 Sep 2026 07:04:14 +0000 Subject: [PATCH] mutter: only enable desktop OpenGL when x11 is in DISTRO_FEATURES mutter fails to configure on a wayland-only distro configuration: Run-time dependency gl found: NO (tried pkg-config and system) ../sources/mutter-50.4/meson.build:191:11: ERROR: Dependency "gl" not found (tried pkg-config and system) The recipe enabled the opengl PACKAGECONFIG unconditionally, which passes -Dopengl=true and makes meson require desktop OpenGL: have_gl = get_option('opengl') if have_gl gl_dep = dependency('gl') Desktop GL is not available here. libGL.so and gl.pc are products of mesa's GLX library - see FILES:libgl-mesa-dev in mesa.inc - and mesa only builds GLX when its x11 PACKAGECONFIG is on, since PACKAGECONFIG[x11] passes -Dglx=disabled when it is off. Without x11 in DISTRO_FEATURES mesa is therefore configured -Dopengl=true -Dglx=disabled -Dplatforms='wayland' and stages only egl.pc, glesv1_cm.pc and glesv2.pc, with no libGL and no gl.pc. The dependency looked satisfied because mesa PROVIDES virtual/libgl unconditionally, so the virtual/libgl entry in PACKAGECONFIG[opengl] resolves at the bitbake level even though nothing ever lands in the sysroot. mesa also installs the GL/*.h headers regardless of GLX, so meson's 'system' fallback clears the header probe before failing on the missing library. mutter builds fine against GLESv2 alone - it only errors out if neither GL nor GLES2 is enabled - and egl plus gles2 are already enabled here, which is the usual configuration for a wayland-only compositor. Gate opengl on x11 so it follows the same condition that decides whether desktop GL exists at all; x11 builds are unaffected.
