JUCE on shared Linux server

Trying to use JUCE keyfile generation on a shared Linux server.
Preliminary trials have brought up this problem:

Please excuse the really basic question, but given the lack of root permissions on this host, does this pretty much mean there’s no solution (have to implement the key gen manually)?

NB ‘HelloLinux’ is a JUCE terminal app using only juce_core and juce_cryptography. Built on Ubuntu.

It looks like the version of the C++ library used by your binary is different to the one on your server. The easiest way to fix this is to compile on the server itself (if possible). The second easiest way is to compile on the oldest Linux distribution you possibly can.

Updating the C++ libraries on the server would be the way to go, but obviously this requires administrator privileges.
