eeeslab / examon Goto Github PK

Thanks again for your quick mail-response. Sorry it took me a bit to compile this issue, I had to make sure the error wasn't due to some strange configuration on the test system.

I ran EXAMON on a test system, a HASWELL, using mod msr and mosquitto, both with and without kpti patch (i.e. tried it with kernel option nopti). Each time it segfaulted in the same function: rdpmc ()

I compiled EXAMON with options -DDEBUG=True and -g and ran it through gdb. It told me a few more details about the segfault, here's what I got: https://pastebin.com/qzwmaLmv

The Linux version I am running according to uname -a is Linux mabus 4.13.0-26-generic #29~16.04.2-Ubuntu SMP Tue Jan 9 22:00:44 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Could it be that the CPU (with family 6, model 60) is not supported?

Which steps could I take to get EXAMON running on said CPU?

Should I test EXAMON on a different CPU e.g. one of Ivy Bridge, Westmere EP, Skylake, Sandy Bridge, Sandy Bridge EP or another Haswell?

I followed the instructions provided in the README on Installation/Building.

However this error appears:

It sounded to me like there could be some issue with OpenSSL. So I reinstalled openssl sudo apt-get install --reinstall libssl-dev. Nothing changed. So I figured I could fetch a more recent OpenSSL, like version 1.1.1. I built it and installed it. However building examon still failed with the same error.

I am running Ubuntu 16.04.4 LTS. uname -a gives me the following:
4.13.0-37-generic #42~16.04.1-Ubuntu SMP Wed Mar 7 16:03:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
Here is a full listing of what make told me upon invocation: https://pastebin.com/HZxKRdn2

I would be happy for a response within the next days. Even a mere hint to a solution would be appreciated.
