简单java jni教程失败
我正在努力使最基本的jni示例正常工作 我正在关注这个,有点老了,但我能找到最好的 步骤:简单java jni教程失败,java,c++,java-native-interface,cygwin,mingw,Java,C++,Java Native Interface,Cygwin,Mingw,我正在努力使最基本的jni示例正常工作 我正在关注这个,有点老了,但我能找到最好的 步骤: 创建HelloJNI.java public class HelloJNI { static { System.loadLibrary("hello"); } private native void sayHello(); public static void main(String[] args) { new HelloJNI().sa
- 创建
HelloJNI.java
public class HelloJNI { static { System.loadLibrary("hello"); } private native void sayHello(); public static void main(String[] args) { new HelloJNI().sayHello(); // invoke the native method } }
- 将
编译成HelloJNI.java
:HelloJNI.class
javac HelloJNI.java
public class HelloJNI {
static {
System.loadLibrary("hello");
}
private native void sayHello();
public static void main(String[] args) {
new HelloJNI().sayHello(); // invoke the native method
}
}

%JAVA\u HOME%
不起作用,您必须使用$JAVA\u HOME
set JAVA\u HOME=C:\Program Files\JAVA\jdk1.8.0\u 102
echo$JAVA\u HOME
gcc-Wl,--添加stdcall别名-I“$JAVA\u HOME\include”-I“$JAVA\u HOME\include\win32”-shared-o hello.dll HelloJNI.c
gcc-3-D\uu int64=“long long”-mno cygwin-Wl,--添加stdcall别名-I“\include”-I“\include\win32”-共享-o hello.dll HelloJNI.c
-bash:gcc-3:未找到命令
让我将gcc-3
更改为gcc
:
gcc-D\uu int64=“long long”-mno cygwin-Wl,--添加stdcall别名-I“\include”-I“\include\win32”-共享-o hello.dll HelloJNI.c
gcc:错误:选项-mno cygwin未知
让我们试着把它去掉
gcc-D\uu int64=“long long”-Wl,--添加stdcall别名-I“\include”-I“\include\win32”-shared-o hello.dll HelloJNI.c
没有这样的文件“jni.h”
让我换成$JAVA\u HOME
gcc-D\uu int64=“long long”-Wl,--添加stdcall别名-I“$JAVA\u HOME\include”-I“$JAVA\u HOME\include\win32”-共享-o hello.dll HelloJNI.c
也许这次起作用了
javahellojni
挂起
java-Djava.library.path=。HelloJNI
