Dear all,

I am under Ubuntu 20.04, X86.64 with CT 7.7. When you make a new project, place a PQConnection, a SQLTransaction and try to connect at runtime with the debugger, the app crash. Without the debugger, the app run. Please see the below example. To crash, a breakpoint must be set on the line
PQConnection1.Connected := true;

Without the breakpoint, the app run. If you run to the breakpoint, then press F8, the following dialog shows:
The file "/build/glibc-eX1tMB/glibc-2.31/elf/dl-error-skeleton.c" could not be found.
Do you like to search for it?

In Design Mode, I can set all the properties for the PQConnection (host, user, password, dbName) and connect without error.
How can this be avoided? Do I need to set the property PQConnection.clientLibrary?

unit Unit1;

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils, PQConnection, SQLDB, Forms, Controls, Graphics, Dialogs;

type

  { TForm1 }

  TForm1 = class(TForm)
    PQConnection1: TPQConnection;
    SQLQuery1: TSQLQuery;
    SQLTransaction1: TSQLTransaction;
    procedure FormActivate(Sender: TObject);
  private

  public

  end;

var
  Form1: TForm1;

implementation

{$R *.frm}

{ TForm1 }

procedure TForm1.FormActivate(Sender: TObject);
begin
     if PQConnection1.Connected = false then begin;
        PQConnection1.DatabaseName:= 'kaluga';
        PQConnection1.HostName:= 'localhost';
      //pgCon.port ??
        PQConnection1.UserName:='kaluga_admin';
        PQConnection1.Password:='kaluga_admin';
        PQConnection1.Connected := true;
        SQLTransaction1.Active:= true;
        showMessage('connected to postgres DB');
     end;
end;

end.    

Thanks

Your PQ version ?
Did you test an other debugger ?. CT support on Linux 3 debuggers.
Some Ubuntu ver have problems with GDB and glibc-2.3x
 

My Postgresql version is 11. In the mean time, I got the same debugger problems on other places as well, so it might not be  Postgresql problem. Maybe it is an Ubuntu problem with gdb, as you suggest. I will try to use an other debugger
