I've had this before with a vendor layer. The culprit was the distro having some weird USERADDEXTENSION messing up with everything. How we found out what it was was by uncommenting: https://git.yoctoproject.org/cgit.cgi/poky/tree/bitbake/lib/bb/siggen.py#n187 187 to 189. Then you go to tmp/stamps/...your-recipe.../ and you'll have more sigdata in there. Use bitbake-diffsigs between the both and you'll find which variable messes up with your build. Hope this helps, good luck! Quentin
