Hi,
I am compiling scikit-learn python package for arm  board but I am facing below errors

william@william:~/sagitta/build-as371$ bitbake python3-scikit-learn
Loading cache: 100% |##########################################################################################################################################################| Time: 0:00:01

atk-native
ERROR: Required build target 'python3-scikit-learn' has no buildable providers.
Missing or unbuildable dependency chain was: ['python3-scikit-learn', 'python3-scipy-native', 'lapack-native']

It seems lapack is not compiled native because of it I am facing the issue

Thanks

right, add

BBCLASSEXTEND = "native" in lapack recipe and fix the needed bits to
get it going.

adding BBCLASSEXTEND = "native" in lapack recipe will give me another error ERROR: Nothing PROVIDES 'gcc-runtime-native'

Is there a another way to make lapack native
