[yocto] core-image-minimal-xfce error

[ravikiran j]

Hi everybody,
I am getting some errors in building of *core-image-minimal-xfce *image.

I am using ubuntu 14.04 build system and Yocto 2.1.

I added the meta-openembedded layer into poky  and configured the
bblayers.con ffile as follows.


 POKY_BBLAYERS_CONF_VERSION = "2"
  4
  5 BBPATH = "${TOPDIR}"
  6 BBFILES ?= ""
  7
  8 BBLAYERS ?= " \
