[yocto] Procedure to build the xfce UI for ODROID XU3 board

[ravikiran j]

I cloned the meta-openembedded layer and added inside the poky.
then changed the conf/bblayers.conf as follow.

I found that meta-xfce layer depends on openembedded core, oe , multimedia
, gnome, and python.
so i made the following changes in the bblayers.conf file.


OKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
  /home/kamama-yocto/yocto/tmp/poky/meta \
  /home/kamama-yocto/yocto/tmp/poky/meta-poky \
  /home/kamama-yocto/yocto/tmp/poky/meta-yocto-bsp \





* /home/kamama-yocto/yocto/tmp/poky/meta-odroid \
/home/kamama-yocto/yocto/tmp/poky/meta-openembedded/meta-xfce \
/home/kamama-yocto/yocto/tmp/poky/meta-openembedded/meta-oe \
/home/kamama-yocto/yocto/tmp/poky/meta-openembedded/meta-multimedia \
/home/kamama-yocto/yocto/tmp/poky/meta-openembedded/meta-gnome \
/home/kamama-yocto/yocto/tmp/poky/meta-openembedded/meta-python \*
  "

then i trying to build the
*image core-image-minimal-xfce*
Building gives the  following errors.

how to solve this problems ?
