Question

我使用Delphi 10.1 Berlin。我已经创建了应用程序，我使用这个库启动（C上的库）

我第一次启动它时发现了libhid.dylib未找到的错误。我已将其添加到rpath并解决了错误。

但是现在当我打开应用程序时，当我尝试从库中调用方法时，我接下来：

这是我链接库的代码。

unit Unit1;

interface

uses
System.SysUtils, System.Types, System.UITypes, System.Classes,     System.Variants,
FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs,
FMX.Controls.Presentation, FMX.StdCtrls;

type
TForm1 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;


{$IFDEF MSWINDOWS}
function DeleteAll():shortstring; stdcall; external 'Project1.dll' delayed;
{$ENDIF}
{$IFDEF MACOS}
function _DeleteAll():shortstring; cdecl; external 'libhidlib.dylib'  ;
{$ENDIF}


 var
 Form1: TForm1;

所以，经过几周搜索我发现的信息，发布后新的OS X版程序员改变了OS X的文件结构（10.9 100％）

德尔福怎么样？项目可能连接到库但不能使用它的方法。
