Re: [meta-oe][PATCH 1/1] kernel-selftest: Add a recipe on kernel selftest

["Hongzhi, Song" <hongzhi.song@windriver.com>]

Hi Raj,

I can continue to fix the error with rpi that you build. But I found 
that rpi gets kernel

from git://github.com/raspberrypi/linux.git;branch=rpi-4.14.y, which is 
not belong

to openembeded. I think that the rpi recipe must make some special 
change which

cause the error.


And the recipe in meta-oe is OK both with glibc and musl. So could you 
build a project

with oe-core's kernel?  If there is no problem, would you merge the recipe?
