只有當在Windows標籤上運行JNA不滿意的鏈接錯誤

我想從我的Java代碼使用JNA加載C DLL。有關的行是只有當在Windows標籤上運行JNA不滿意的鏈接錯誤

rlib = (rfidlib) Native.loadlibrary("rfidlib",rfidlib.class);

我把DLL放在Windows機器的同一個文件夾中並運行它。它運行良好。當我把它放在Windows/System32文件夾中時也能正常工作。但是，當我將其複製到Windows標籤時，它會引發以下異常。

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: The speci

我在選項卡和DLL中的Java版本都是64位版本。我已經嘗試將jar保存在選項卡中的System32文件夾以及jar執行位置。我仍然得到這個錯誤。我該如何解決這個問題？請指教。它在我的Windows機器中工作正常。

你是什麼意思的「Windows標籤」？ – technomage

其安裝了Windows 8.1的選項卡。 – mayooran

你的意思是「平板電腦」？將系統屬性'jna.library.path'設置爲指向DLL所在的目錄。 – technomage

這是因爲C DLL的依賴關係丟失了。使用依賴關係walker來識別依賴關係，一旦它們被安裝，它就可以工作。
