Re: Error when building eSDK for a `docker load`able tarball
And as far as I understand you tried to build some extensible SDK against an x86-64 container.
Please note, that my SDK most likely contains a bit more than the "standard" stuff, but this should not make much of a difference here.
I take a container-x86-64:
bitbake app-container-image-mosquitto-oci 
bitbake app-container-image-mosquitto-oci -c populate_sdk 
bitbake app-container-image-mosquitto-oci -c populate_sdk_ext
breaks in a similar way
So it looks like it's extensible SDK specific.
Can you please try with the "standard" sdk instead of the extensible sdk to see if this works for you?
You might want to play with IMAGE_CONTAINER_NO_DUMMY = "1" which is defined in poky/meta/classes/image-container.bbclass and try to build a container with a kernel as a workaround in case you build an eSDK.
