异常线程 “main” java.lang.UnsatisfiedLinkError中：Native.initiate（I），而从Java

运行本机DLL V本是Native.cpp：异常线程 “main” java.lang.UnsatisfiedLinkError中：Native.initiate（I），而从Java

// Native.cpp : Defines the exported functions for the DLL application. 
// 
#include "stdafx.h" 
#define ALLEGRO_NO_MAGIC_MAIN 
#include <stdio.h> 
#include <string> 
#include <windows.h> 
#include "generic_interface.h" 
#include "NativeC.h" 

using namespace std; 

// Some useful defines I liked from Sun's stuff 
#define JNIEXPORT __declspec(dllexport) 
#define JNICALL __cdecl 
#define jint long 


typedef ExportedClass* (__cdecl *exported_class)(); 
HINSTANCE temptDLL; 
ExportedClass** importedClasses; 
char** classNamePerIndex; 
int libraryLength = 0; 

JNIEXPORT void JNICALL _JAVA_initiate(HNative *self, jint libraryLength) { 
    importedClasses = new ExportedClass*[libraryLength]; 
    classNamePerIndex = new char*[libraryLength]; 
}

和Java类，它实现和负载从上面的Native.cpp文件生成此机dll是这样的：

public class Native { 
    // guess? 
    native public void initiate(int libraryLength); 


    // Loads the file Native.DLL at run-time 
    static { 
    System.loadLibrary("Native"); 
    } 

    // Constructor 
    public Native() 
    { 
    } 

}

但同时呼吁

(new Native()).initiate(1);

我得到这个运行时错误：

在线程异常“主要” java.lang.UnsatisfiedLinkError中：Native.initiate（我）V

我试图_JAVA_initiate重命名为JAVA_initiate和NATIVE_initiate和_JAVA_NATIVE_inititate甚至JAVA_NATIVE_inititate ，但它仍然没有工作

该库加载完美，只是在调用本地方法时，它给出了链接错误。

编辑：下面列出的是已包含在Native.cpp
