Hi,

Im having trouble and I hope ive put this topic in the right place,

Ive just started learning Delphi and Im trying to compile a coulpe of
really simple
programs but when i compile them it gives me 16 files aswell as a
backup folder,
which is not a problem but when i try running the .exe (Im using
widows xp)
absolutely nothing happens.

It is very fustrating.

If anyone could help that would be great!

hard to say something without sources. maybe you program really does
nothing? can you copy-paste your code here?

Well you need to give a bit more info:

Which version of Lazarus? and FPC? (see help menu / about dialog)

Do you try to run the exe within lazarus or from windows directly?

If you run within lazarus check your debugger settings (environment
menu => options => Tree: Debugger). It should be "gnu debugger (gdb)"
and point to an executable of gdb.exe.

What do you expect to happen? That is did you write a GUI app with
Forms? or a console app using readln/writeln etc?

For console app there is a switch in the linking tab of the compiler
options, so you get the dos window in which to run. You also must make
sure it does not close faster than you can see it.

For GUI apps, does a simple form, with absolutely *no* additional code
work?

As this is my very first time using this program,
half of what you just said makes absolutely no sence to me,

the Lazarus version im using is 0.9.26.2 beta
and theFPC is 2.2.2

Code: [Select]unit unit2;

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils, FileUtil, LResources, Forms, Controls, Graphics,
Dialogs,
  StdCtrls;

type

  { TForm1 }

  TForm1 = class(TForm)
    Button1: TButton;
    Label1: TLabel;
    procedure Button1Click(Sender: TObject);
    procedure Label1Click(Sender: TObject);
  private
    { private declarations }
  public
    { public declarations }
  end;

var
  Form1: TForm1;

implementation

{ TForm1 }

procedure TForm1.Label1Click(Sender: TObject);
begin

end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  Label1.Caption := 'Hello World, Part II';
end;

initialization
  {$I unit2.lrs}

end.


im trying to run it directly in windows as i press the Green arrow
(RUN?) and
it puts all the files in the folder that ive saved the project in,
and so then i try running the .exe and nothing happens,

its just a little form with a button and when the button is pressed
the text says "hello world".

thats about all i can tell you.

Also when trying to run it in the Lazarus program it asks me for
unit2.lrs,
whats up with this file?

While not necessarily wrong, I wonder why it is "unit2". A single form
app would normally have a "unit1".

Maybe you did have one form, added another (or copied it), and removed
the first? In that case the 2nd form isn't automatically shown.

Please check in the project menu => project options => tab: "Forms".
Your form must be in the list of "auto-create forms".

If no form is auto created that would explain why the app terminates
immediately.

unit2.lrs is the "resource" for tour form, it contains all the
settings you mad in the Object-Inspector. Lazarus should create it
automatically (from the unit2.lfm file, which is a text file
containing the same settings)

So I wonder why Lazarus would ask for it. Can you copy the messages
during compilation? (right mouse on message window: "copy all and
hidden")

Just to be save: View the project source (from the project menu). And
check that your unit2 is used, and if any "unit1" is still used
(depends on if you want a unit1 to be used)

if a unit1 is also used, and exists, make sure it doesn't have a form
of the same name ("Form1").

The easier way is to start from scratch and make sure you just save
the one unit you need (you can choose any name you wish)

simply delete this line (  {$I unit2.lrs} )
