Hi!
I'm developing a linux daemon in this VM: lubuntu-18.04-alternate-
amd64.
And after build and run from console for tests:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i sudo
./myapplication -rit's possible get some expected results.
But if I copy my application to another computer (not VM):
Ubuntu Server 20.04 LTS (without graphical interface)
to try run the same prompt commands to test my application then I'm
receiving the folowing error:

"error while loading shared libraries: libgdk-x11-2.0.so.0: cannot
open shared object file: No such file or directory"

I'm not a Linux expert, but this library is about graphical interface,
right?
If yes, I belive that some graphic dependency exists in my code, but
I'm not finding.

My project file has this uses list:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i Uses{$IFDEF
UNIX}  CThreads,{$ENDIF}  Interfaces, DaemonApp, lazdaemonapp,
daemonmapperc3scnpj, daemonc3scnpj,  indylaz, zcomponent  { add your
units here };
My daemon has:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i uses 
Classes, SysUtils, SyncObjs, IdSchedulerOfThreadPool, IdHTTPServer, 
IdCustomHTTPServer, IdContext,  DaemonApp,  variants, ZConnection,
ZDataset, ZDbcIntfs, ZCompatibility;
And my DaemonMapper:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i uses 
Classes, SysUtils, DaemonApp;
And my Project Inspector is attached.

Can any Linux expert give me any suggestions, please?

It might be the Indy components that pull in the visual code. You can
either try to use the NoGUI widgetset or you need to find out which
part of Indy pulls in the GUI code and adjust accordingly.

This is library of X Server, basic graphical interface. It is not full
desktop GUI like KDE Plasma, Gnome. In case you want to GUI program on
Linux server you also need some libraries of X Server.

As @PascalDragon mention "try to use the NoGUI widgetset", replace
Indy with Synapse or Lnet.

You all are right guys!
Using NoGUI widgetset solved the problem!
Thanks!
