Exception: Failed to compile BPF module <text>

I am facing the following error after running the code for Meshinsight's profiler:

ryzen02@ryzen02-rs-iiitd:~/meshinsight$ sudo python3 ./meshinsight/profiler/offline_profiler.py --latency --cpu

I am using Linux kernel version 5.4.0 , Ubuntu 18.04, Python 3.8, libllvm 6.0 , libclang 6.0 , llvm 6.0

I would be obliged if someone can help with this !

Thanks for trying MeshInsight!

It seems to be a BCC issue - will this help? iovisor/bcc#3752

Hi @Romero027
I believe Ubuntu 18.04 and kernel 5.4 have problems in installing bcc. https://gitlab.com/gitlab-com/gl-infra/reliability/-/issues/12052

Could you let me know the ideal version for my ubuntu machine and kernel in order to run MeshInsight?

MeshInsight should work on Ubuntu 20.04.
