Build dedicated server on Linux with Steam

Hi there!
We are trying to build a dedicated server on a Linux Server with Steam integration.

We are able to build it in a windows environment, but when starting the server in Linux we get an error stating “SteamClient.so is missing”.

Have tried to acquire this file from steamcmd for Linux. We then get “ELFCLASS32 error”, which has to do with x64/x86 architecture mismatch.
We can’t find an x64 SteamClient.so and we can’t figure out how to build a dedicated server with x86.

Sorry for the weird formulation, but in short: How do we build a dedicated server on Linux with Steam integration?

Thanks in advance!
