RemoteDB client on linux (arm64)

I need build a RemoteDB consolle application on a Rpi4 SBC.
Is it possible compile RemoteDB under Lazarus ?

Unfortunately not, currently it only supports Delphi.

is it possible instead develop/compile XData clients ?

Unfortunately that is also not possible.

I asked because have seen that Sparkle is available on Rpi...
Am I wrong ?

No, Sparkle is not supported on Rpi. Not sure if you can let me know where have you seen such information?

on TMs web page I have seen Linux as supported platform,
but from your answer I guess is intended for x86 only...

Yes, only the platforms supported by Delphi itself, since Sparkle is compiled with Delphi. Delphi actually compiles for Linux x64, not ARM.
