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.
