Re: [PATCH] bitbake: Resolve symlink duplicates in layer paths

The user doesn't intentionally add the same layer twice — this happens when the working directory uses a symlink path (e.g., /home/pokybuild → /srv/ pokybuild ). Running bitbake-layers add-layer /srv/pokybuild/.../meta-mingw resolves to a different string than what's already in bblayers.conf (which was set via the symlink path), causing ERROR: Found duplicated BBFILE_COLLECTIONS.

The main fix is using os.path.realpath() inste ad of os.path.abspath() in do_ add_layer() and canonicalise_ path() , which prevents the duplicate from being added in the first place.

Regarding the warning in cookerdata.py — I can remove it if you prefer silent deduplication. I added it for visibility when users have manually edited bblayers.conf with symlink paths. Would you prefer it to silently resolve duplicates instead?

This behavior as you shared in root ticket bugzilla https://bugzilla.yoctoproject. org/show_bug.cgi?id=15591 ( https://bugzilla.yoctoproject.org/show_bug.cgi?id=15591 )

I try to implement the fix
