There is a dependency on python3.10, so if the build machine has an older version, we do fail. We should use python-native from yocto instead.

Chroot env is plain 18.04 chroot (similar to CI) with minimal dependencies added as per Yocto documentation page's apt cmdline.

The chroot did only have python3.6 initially, that failed on call available in python3.7 . Upreved host python (should not have to). Plus had to call

 python3 -m pip install importlib_metadata  

Once I had python3.7 as default.

So there are host dependencies for sure.

Also there is a dependency to jpeg(-native?) in skia it seems :

FAILED: yocto_native/obj/skia/skia/SkJPEGWriteUtility.o
