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.

How did you "try this"?

I get the same if I try an simply Unit with form, also an empty Start
Form

QuoteCode: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =

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.
