Java JNI EXCEPTION_ACCESS_VIOLATION

我是JNI的新手，试图获得一个简单的Hello World程序来使用Windows 7和cygwin的gcc编译器。这里的各种组件：Java JNI EXCEPTION_ACCESS_VIOLATION

Hello.java：

public class Hello { 
    public static native void sayHello(); 

    public static void main(String[] args) { 
     System.loadLibrary("Hello"); 
     sayHello(); 
    } // end main 
} // end class Hello

我再执行下面的命令列表构建.h文件：

javac Hello.java 
javah Hello

这会自动构建你好。 h文件。为了完整起见，这是这里：

/* DO NOT EDIT THIS FILE - it is machine generated */ 
#include <jni.h> 
/* Header for class Hello */ 

#ifndef _Included_Hello 
#define _Included_Hello 
#ifdef __cplusplus 
extern "C" { 
#endif 
/* 
* Class:  Hello 
* Method: sayHello 
* Signature:()V 
*/ 
JNIEXPORT void JNICALL Java_Hello_sayHello 
    (JNIEnv *, jclass); 

#ifdef __cplusplus 
} 
#endif 
#endif

我然后建立相应的文件HELLO.C：

#include <stdio.h> 
#include "Hello.h" 

JNIEXPORT void JNICALL Java_Hello_sayHello(JNIEnv *env, jclass c) { 
    printf("Hello World\n"); 
}

然后，我编译使用下面的命令/链接C代码：

gcc -I/cygdrive/c/Java/jdk1.8.0_45/include -I/cygdrive/c/Java/jdk1.8.0_45/include/win32 -Wl,--add-stdcall-alias -shared -o Hello.dll Hello.c

最后，我重新编译了java文件。（难道我竟然真的需要这样做？）：

javac Hello.java

我用这个Makefile（我还相对较新建设的Makefile）完成所有与一个make命令的步骤：

CC=gcc 
CFLAGS= 
LDFLAGS= 
JAVALIB="/cygdrive/C/Java/jdk1.8.0_45/include" 
JAVALIBWIN32="$(JAVALIB)/win32" 

all: Hello.dll 
     javac Hello.java 

Hello.dll: Hello.h 
     $(CC) -I$(JAVALIB) -I$(JAVALIBWIN32) -Wl,--add-stdcall-alias -shared -o Hello.dll Hello.c 


Hello.h: Hello.class 
     rm -f Hello.h 
     javah Hello 

Hello.class: Hello.java 
     javac Hello.java 

clean: 
     @rm -f *.dll *.class

一旦我执行程序（使用命令“java你好”），我收到此错误：

$ java Hello 
# 
# A fatal error has been detected by the Java Runtime Environment:

而且，所得到的错误日志是这样的：

我一直在按照这个site一行一行的指导。我无法复制的唯一东西是-mno-cygwin选项，因为我使用的是gcc版本4.9.2，并且该选项无法识别。

任何人都可以指向正确的方向吗？非常感谢！

只是为了让所有人保持最新状态：第二次javac编译是不必要的。另外，我能够使这个软件在Ubuntu linux发行版上运行。这肯定与Cygwin有关，因为它在Linux上非常简单。 – Gary

这绝对是Cygwin环境。我转移到Ubuntu发行版，链接的指南按照广告版本工作。

＃C [cygwin1.dll + 0xb9309] 说它实际上在cygwin中崩溃。我在linux上建立了一个jni库，并将dll交叉编译到Windows。 –
