Hello Chen, I'm not sure why you're not seeing this, but the fix is almost certainly prefixing the string with r, e.g. making it a raw string. Oe-core has had lots of similar fixes recently, e.g.: https://git.openembedded.org/openembedded-core/commit/?id=24b0ba00d4f0b4d9834f7693ecb6032dfc534a80 Alex
