This file can make an image to run gtk over directfb.

I think this ought to be done on core-image-gtk not a specific one for directfb as it depends on a distro feature and you can't just generate an image with this, if the distro has no directfb feature enabled.

I can add a mechanism to inform user to add "gtk-directfb" to DISTRO_FEATURES by adding like the following steps
$touch meta/class/gtk-directfb.bbclass
$cat meta/class/gtk-directfb.bbclass
python () {
    import os
    import signal
    packages = d.getVar('DISTRO_FEATURES', 1).split()
    for pkg in packages:
        if pkg == "x11":
            print("Please remove x11 from DISTRO_FEATURES, use \"gtk-directfb\" instead of it\n")
            pid = os.getpid()
            os.kill(pid,signal.SIGCLD) # it could have some issues
}

$cat core-image-gtk-directfb.bb
LICENSE = "MIT"
PR="r0"

inherit gtk-directfb

LIC_FILES_CHKSUM = "file://${COREBASE}/LICENSE;md5=3f40d7994397109285ec7b81fdeb3b58 \
                    file://${COREBASE}/meta/COPYING.MIT;md5=3da9cfbcb788c80a0384361b4de20420"

DEPENDS += "task-core-gtk-directfb"

RDEPENDS_${PN} += " \
    task-core-gtk-directfb-base \
    "

inherit core-image

IMAGE_INSTALL += "\
    ${POKY_BASE_INSTALL} \
    task-core-basic \
    module-init-tools \
    task-core-gtk-directfb-base \
"
Do you have any comment about above method ?

Thanks
Yan
