[yocto] LINUX_VERSION issue in recipe

[Damien LEFEVRE]

Hi,

This must be a stupid basic question. I have the following recipe append:

keymaps_1.0.bbappend
-----------------------------------------------------------------------------
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
SRC_URI_append = " file://keymaps.service \
                   file://keymap.sh \
"

do_install_append() {
    install -d ${D}${sysconfdir}
    ln -sf /usr/share/keymaps/i386/qwerty/fi.map.gz
${D}${sysconfdir}/keymap-${LINUX_VERSION}.map.gz

    install -d ${D}${systemd_system_unitdir}
    install -m 0644 ${WORKDIR}/keymaps.service ${D}${systemd_system_unitdir}
}

FILES_${PN} += " ${sysconfdir}/* \
                 ${systemd_system_unitdir}/* \
"

inherit systemd
SYSTEMD_SERVICE_${PN} = "${PN}.service"
-----------------------------------------------------------------------------

The LINUX_VERSION is not expanded and the final symlink name becomes  /etc/
keymap-.map.gz.

What's correct way to get the linux version in the recipe files?

Thanks,
-Damien
