Hi @kwoo, are you sure you followed all of the steps? The page you give links to:

https://alice-doc.github.io/alice-analysis-tutorial/building/custom.html

…and specifically, that tells you that to build on Ubuntu 20.04, you need to install some system packages:

Hi @twilken ,
Sorry for the late reply. Actually, I am still building it.
I thought that following the webpage https://alisw.github.io/alibuild/ was enough to install alibuild.
Thank you for your solution.
your solution for Error building O2Physics in Ubuntu 20.04.6 LTS
was also really helpful.

Thanks a lot.
