<yangsuli@gmail.com>Update: I suspect the problem has something to do with the compiler does not accept the noexcept constructor, so I switched a a newer version of g++ (10.3.0).
Now I am having a different (but similar) compiling error:

<avi@scylladb.com>This is a problem with boost. What version of boost are you
using?

Does seastar only work with specific versions of g++/boost etc? Where could I find such information?
Thanks!

Suli, it seems that you need bosot v1.73 and up to compile Seastar with C++20. see https://github.com/boostorg/test/commit/8ac88c62dcc809d42daf8b6bef10f7adecc46dd1@Avi, probably we could bump up the required boost version to at least 1.73? if we don't have any regular test compiling Seastar with older boost. i see our CI is using GCC-11 + boost v1.74 + C++{17,20} though. see [0,1]
Ok. It's just two years old ([2]), but if it's 1.72 is broken in
such a basic way, we don't want to deal with it.
Possibly we can make the requirement dependent on the C++
standard, but probably not worth the effort.
This will make it impossible to develop on Ubuntu 20.04 LTS, but
given that 22.04 LTS is out, maybe that's okay.
