I am having a hard time building BPF samples by doing a make in
samples/bpf. While I am debugging that, I ran into the Python issue.
Even though the system has libpython2.7-dev:
If I just do a 'make' inside tools/build/feature/ I get:
Python.h: No such file or directory
This led me to this patch which fixes Python feature detection for me.
I am not sure if it is the right fix for Python since it is hardcoded
for Python version 2, but I thought it could be useful.
My system is a Debian buster release.
