My main objective is to run snappy player (https://wiki.gnome.org/Snappy) on target machine (BeagleBone Black) so, I wrote a recipe for Snappy player(snappy_1.0.bb) as below
LICENSE = "GPLv2"
LIC_FILES_CHKSUM = "file://COPYING;md5=686e6cb566fd6382c9fcc7a557bf4544"
SRCREV = "e73fabce4c397b40d490c74f6a6a0de000804f42"
SRC_URI = "git://git.gnome.org/snappy"
S = "${WORKDIR}/git"
RDEPENDS_${PN} = "gtk+3 gstreamer1.0 glib-2.0 clutter-1.0 gstreamer1.0-plugins-base libxtst clutter-gst-3.0 clutter-gtk-1.0 libx11 cairo gdk-pixbuf"
# inherit line
inherit pkgconfig autotools
FILES_${PN} += "${datadir}/*"
Added this recipe name in local.conf
IMAGE_INSTALL_append = " snappy"
The build (bitbake core-image-sato) was successful, when I ran "snappy" on target(BeagleBone Black) I am getting below error response.
sh-4.4# snappy
libEGL warning: DRI2: failed to authenticate
libEGL warning: DRI2: failed to authenticate
libEGL warning: DRI2: failed to authenticate
(snappy:763): clutter-CRITICAL **: Unable to initialize clutter: Unable to initialize the clutter backend: no available drivers found.
As per my Understanding in my recipe I have resolved all dependencies for Snappy player (such as clutter, gstreamer, gtk etc.). I'm unable to figure out why snappy player is throwing error?
Even tried by adding PREFERRED_PROVIDER_virtual/egl ?= "mesa" in local.conf yet getting the same error.
