I have found that having a {$I filename} in a unit file apparently prevents Omnipascal from being able to resolve references after that. In the following example, cs1 is not found as a reference unless the {$I filename} is removed from unit_1.pas:
unit MainForm;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;
type
TForm1 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
uses
unit_1;
{$R *.dfm}
procedure TForm1.Button1Click(Sender: TObject);
begin
MessageDlg(cs1, mtWarning, [mbOK], 0);
end;
end.
unit Unit_1;
interface
{$INCLUDE C:\Junk\Delphi\VSCode Test\2\Units\COMPIL.INC}
const
cs1 = '1';
implementation
end.
Compil.inc:
{$DEFINE TESTDEF}
This is v0.19.0 Am I doing something incredibly silly or does the $I break things?
