I'm pretty new to yocto and am trying out different poky images. I am able to 
build and create an iso with a couple of tweaks to the honister branch (using 
the default qemux86-64. However when I add meta-intel and build for 
intel-corei7-64 (which seems to build just fine), attempting to use wic to 
create mkyhbridiso gives the following error that I am looking to resolve. Any 
suggestions would be much appreciated.

Regards,

Bruce

*I have modified BBLAYERS in bblayers.conf to add meta-intel:*
BBLAYERS ?= " \
/home/bruce/Yocto/TestPoky/poky/meta \
/home/bruce/Yocto/TestPoky/poky/meta-poky \
/home/bruce/Yocto/TestPoky/poky/meta-intel \
/home/bruce/Yocto/TestPoky/poky/meta-yocto-bsp \
"

*I have changed/updated the following in local.conf:*
MACHINE ??= "intel-corei7-64"
IMAGE_INSTALL:append = " packagegroup-core-buildessential"
IMAGE_FSTYPES:append = " wic cpio.gz"
WKS_FILE:append = " mkhybridiso"

*wic create output is as follows:*

thinkmate:~/Yocto/TestPoky/poky$ wic create mkhybridiso -e  
core-image-bgc-intel1
