e-sdk does not build

Trying to build esdk for qemuarm64.

bitbake core-image-minimal -c do_populate_sdk_ext

However it fails at the end looking for local.conf which isn't present.

ERROR: core-image-minimal-1.0-r0 do_populate_sdk_ext: Error executing a python function in exec_python_func() autogenerated:

I had to create a local.conf with contents of conf/site.conf and MACHINE variable. Is there a better way ?

thanks for report @karthikpoduval I have seen this error too in past so I think there is some room for improvement, I think by default Yoe does not create a local.conf and perhaps thats whats happening here. Can you check if you have a conf/local.conf in your build dir ?

If creating an empty local.conf is what fixes this issue then perhaps its an issue with OE-Core and we should open a bug
with yocto project bugzilla as well so it can be fixed there to handle absense of local.conf graciously.

@karthikpoduval a fix has been posted here https://patchwork.openembedded.org/patch/176454/ please test it out in your environment and report back if it fixes the issue

@kraj thanks for the patch, it fixes the issue and build succeeded.
