                Building scylladb/seastar on Ubuntu 22.04
              
          
    Seastar is a modern C++ framework for building highly scalable event-driven asynchronous applications.
As of this writing, the accompanying Dockerfile builds the Seastar library on Ubuntu 24.10.
The README.md doesn't refer to any specific Linux distro and release.
To build Seastar on Ubuntu 22.04 (LTS):
The default gcc compiler version is gcc 11.4.0 and it does not support C++20 (required for building Seastar).
