Hi Alex, This change need tweaks in rust.py and rust recipe to support multilib builds. Without tweaks rust selftest and rust multilib builds will fail. Required changes can be found here : https://git.openembedded.org/openembedded-core-contrib/commit/?h=deepesh/sunil-rust-issue&id=44ce23e12e411ef9a1724e79c2b6ac6d5f0ddedc Regards, Deepesh
