我正在使用CYGWIN 64位版本，但无法得到确切的错误。 以下是javatoc.java文件代码
import java.io.*;
public class javatoc
{
public native void print();
static{
System.loadLibrary("javatoc");
}
public static void main(String args[])
{
new javatoc().print();
}
}
这是javatoc.c文件代码
#include "jni.h"
#include <stdio.h>
JNIEXPORT void JNICALL Java_javatoc_print
(JNIEnv *evn, jobject obj)
{
printf("Hello World");
}
用于执行的命令：
javac javatoc.java
javah -jni javatoc
gcc -I"C:/Program Files/Java/jdk1.8.0_131/include" -I"C:/Program Files/Java/jdk1.8.0_131/include/win32" -Wall -D_JNI_IMPLEMENTATION_ -Wl,--kill-at -shared javatoc.c -o javatoc.dll
任何人都可以帮助我解决这个问题。

我无法让JNI与Cygwin的g++一起工作 - 这会导致对cygwin1.dll的依赖，后者与JNI机制发生冲突，导致崩溃。但使用/bin/x86_64-w64-mingw32-g++.exe为我解决了问题。
