This can be further refined to: conf/local.conf: PREFERRED_PROVIDER_virtual/libgl = "mesa-gl" PREFERRED_PROVIDER_virtual/mesa = "mesa-gl" DISTRO_FEATURES_append = " opengl" DISTRO_FEATURES_remove = "x11" bitbake mesa-gl Error is the same: meson.build:455:4: ERROR: Problem encountered: building dri drivers require at least one windowing system or classic osmesa > --Mark > >> -- >> Denys >> >> >>> Signed-off-by: Mark Hatle <[email protected]> >>> --- >>> meta/recipes-graphics/mesa/mesa-gl_20.0.1.bb | 6 ++++-- >>> 1 file changed, 4 insertions(+), 2 deletions(-) >>> >>> diff --git a/meta/recipes-graphics/mesa/mesa-gl_20.0.1.bb >>> b/meta/recipes-graphics/mesa/mesa-gl_20.0.1.bb >>> index d4b1c1c454..5674c6b1fe 100644 >>> --- a/meta/recipes-graphics/mesa/mesa-gl_20.0.1.bb >>> +++ b/meta/recipes-graphics/mesa/mesa-gl_20.0.1.bb >>> @@ -6,5 +6,7 @@ PROVIDES = "virtual/libgl virtual/mesa" >>> >>> S = "${WORKDIR}/mesa-${PV}" >>> >>> -PACKAGECONFIG ??= "opengl dri ${@bb.utils.filter('DISTRO_FEATURES', >>> 'x11', d)}" >>> -PACKAGECONFIG_class-target = "opengl dri >>> ${@bb.utils.filter('DISTRO_FEATURES', 'x11', d)}" >>> +REQUIRED_DISTRO_FEATURE = "x11" >>> + >>> +PACKAGECONFIG ??= "opengl dri x11" >>> +PACKAGECONFIG_class-target = "opengl dri x11" >>> -- >>> 2.17.1 >>> >> >>> >> > > >
