[ShankarRatneshwaran]

After installing the oneAPI base toolkit on my Linux machine, emon dosent seem to see the SEP and PAX drivers

The solution according to documentation seems to be 

$ cd <install-dir>/sepdk/src

$ ./insmod-sep -q

Dosent seem to solve the problem

Tried to build the drivers but that seems to be erroring out at the very end

Hi,

Thankyou for posting in Intel Communities. 

Could you please try to install the sampling driver again.

cd <install-dir>/sepdk/src

./build-driver

Please follow the below link for more information to build the driver.

If the issue still persists please share the following details:

1. OS you are using
2. VTune version
3. Hardware you are using

Thanks.

Issue is still there. The clue to solving the issue is actually a bad mv statement in the Makefile

-------------------------

mv: target 'socwatch2_15-x32_64-5-x32_64-5.11.0-44-genericsmp.ko' is not a directory

-------------------------

The build is actually successful but he mv statement above errors out
