Failing to build drivers with "Linux kernels prior to 2.6.x are unsupported"

Hi

I'm trying to use and install VTune on two of my Debian servers, and it worked perfectly for one but fails for the others.
The driver install fails  when trying to compile the drivers with the following message:

"************ Building socperf3.ko driver ************

ERROR: Linux kernels prior to 2.6.x are unsupported ... exiting.

ERROR: Failed to build socperf3.ko driver"

Complete log in attachement.

I'm running Debian 10. "uname -r" returns "5.4.0-0.bpo.2-amd64".
It seems to me the error is probably just the script failing to find something in the local sources.

I've run "apt-get install linux-headers-5.4.0-0.bpo.2-amd64" and it's normally installed.

Any idea what more steps can I take?

Thanks!
