I can't seem to find any information about this error, but I keep getting variations of this when building hardknott:

Exception: NotADirectoryError: [Errno 20] Not a directory: '/home/yocto/rpi64/build/tmp/sysroots-components/x86_64/gmp-native/usr/lib/pkgconfig/gmpxx.pc' -> '/home/yocto/rpi64/build/tmp/work/x86_64-linux/libmpc-native/1.2.1-r0/recipe-sysroot-native/usr/lib/pkgconfig/gmpxx.pc'

I'm building in a container, and I've tried building the tip of the hardknott branch, the hardknott-3.3.1 tag, and the release tarball (http://downloads.yoctoproject.org/releases/yocto/yocto-3.3/poky-hardknott-25.0.0.tar.bz2). All fail with the NotADirectory exception in different recipes. I've attached logs from building the hardknott-3.3.1 tag and from the release tarball.

The additional layers I'm using are (cloned from the tip of their respective hardknott branches):

meta-openembedded

meta-raspberrypi

meta-security

It must be something with my setup because I've searched everywhere for this issue and I can't find anything. Does this sound familiar to anyone?
