Pascal DLL
 

Im trying to compile a DLL to use with mIRC (chat client with an integrated language)

library dll;



uses

    SysUtils,

    Classes,

    Windows;



function Test(mWnd, aWnd : HWND; data, parms : PChar; show, nopause : boolean) : integer; stdcall;

var

   s : string;

begin

     s := 'Hello World';

     strcopy(data, PChar(s));

     result := 3;

end;



begin

end.



exports Test;

Compiler: Dev-Pascal 1.9.2

Im getting one error:
- Fatal: Can't find unit CLASSES

I can compile if i remove Classes, but then i can't access the function im trying to export (Test)

Can anyone suggest a solution?

Re: Pascal DLL
 

Im surprised that classes would stop you seeing the exported function, but then Im not up on dev-pascal.
