Hi,

I want to modify linux source that is unpacked to tmp directory when building yocto and keep it in a separated folder. Next time when I want to build yocto, I need this separated linux source to be builded with it. I followed this [guideline](http://www.yoctoproject.org/docs/1.6/dev-manual/dev-manual.html#building-software-from-an-external-source) and I modified the source meta-digi/meta-digi-arm/recipes-kernel/linux/linux-dey.inc according to the guideline:

SRC\_URI := "   
file://defconfig   
${KERNEL\_CFG\_FRAGS}   
"  
INHERIT += “externalsrc”  
EXTERNALSRC\_pn-myrecipe = “/home/user/Documents/linux-3.14”

However, when I rebuild yocto, I get this this error:  
ERROR: Task 71 (/home/user/Documents/dey-1.6/sources/meta-digi/meta-digi-arm/recipes-kernel/linux/linux-dey\_3.10.bb, do\_configure) failed with exit code ‘1’

How can I resolve this problem?  
Thanks.

Obviously Digi Embedded Yocto DEY-1.6.7 was done to support kernel 3.10 only.

You are using a recipe for kernel 3.10 which does not work with kernel 3.14.

Either you wait for Digi to release DEY-1.7/DEY-1.8 with a newer kernel or you have to change meta-digi-arm yourself to make the kernel 3.14 configure/compile in this environment
