Java JNI HellowWorld UnsatifiedLinkError可以'；找不到依赖库

我尝试了Hello world JNI，来自：

我学习了Java类：

public class ACTICamWrapperJNI {
    public native void displayMessage();
  static 
  {
    System.loadLibrary("HelloWorldImp"); 

}

}

打电话进来：

     public static void main(String args[]) {

            //</editor-fold>
    System.out.println(System.getProperty("java.library.path"));

   ACTICamWrapperJNI test = new ACTICamWrapperJNI();
   }

我使用了QT文件夹中的MINGW32的gcc（希望没问题）

注意：我必须添加共享，否则会出现错误：

 undefined reference to `WinMain@16'

C:\Development\testJNI>"C:\Program Files (x86)\Java\jdk1.7.0_40\bin\java.exe" Main
Exception in thread "main" java.lang.UnsatisfiedLinkError: HelloWorld.displayMessage()V
        at HelloWorld.displayMessage(Native Method)
        at Main.main(Main.java:9)

请注意，我已经确保运行的是x32 jdk的java，并使用x32版本进行编译，因为我的系统上也有x64

在NetBean IDE上也尝试过，但遇到了问题：

Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Windows\System32\HelloWorldImp.dll: Can't find dependent libraries

谢谢

< P>我知道这是有答案的，但我确定，如果您是作为调试进行编译，它就不能再分发到另一台PC；您可以尝试编译发行版，这应该可以工作。我只是用这个来解决
