Hi @georgthegreat, thank you for reporting an issue!

Could you please specify OS and compiler with versions?
Also, do you use these client options in your code?
When do you see the warning, while building your app or while building clickhouse-cpp?

Hi!

I am using clang 14.0.x on linux-amd64.
The issue causes compilation error in client code even if the client is not using deprecated fields.
We have -Werror-deprecated-declarations in our CFLAGS, hence I had to remove the [[deprecated]] declaration.
