doesn't work with Linux, again...
« on: August 14, 2025, 09:06:04 pm »
I use Linux Mint and fpc deluxe
simple console pgrams are working but nothing with forms
If  I try this I got
Code: [Select]
program ggggklpi;

{$mode objfpc}{$H+}

uses
  SysUtils, unit2;

var
  Serial: Text;
  Device, Line: string;
begin
  Device := '/dev/ttyUSB2';

  AssignFile(Serial, Device);
  {$I-}
  Reset(Serial);
  {$I+}
  if IOResult <> 0 then
  begin
    WriteLn('Fehler: Konnte ', Device, ' nicht öffnen.');
    Halt(1);
  end;

  WriteLn('Warte auf Nachrichten auf ', Device, ' mit 9600 Baud...');

  while True do
  begin
    {$I-}
    ReadLn(Serial, Line);
    {$I+}
    if IOResult = 0 then
      WriteLn('Empfangen: ', Line)
    else
     Sleep(100);
  end;

 // CloseFile(Serial);
end.

Code: Pascal  [Select][+][-]
  1. program ggggklpi;
  2.  
  3. {$mode objfpc}{$H+}
  4.  
  5. uses
  6.   SysUtils, unit2;

This looks like you created a "simple program" (or other non-gui-app), and simply added a unit with a form.

But for forms, you need some setup in your app => all that is done for you if you chose the correct application type, when creating your project.

You must include "uses interface", and in the project settings you must make sure a widget set is selected.

Then you must create a TApplication from the Forms unit. And you must run it. It must run in its loop. You can't have your own loop running.
