JNI - “Cannot open include file: 'jni_md.h'”

Question

This sample program is meant to call a native method written in C.

Java Code

class HelloWorld {

    private native voi         


        

Answer 1

Try this,

HelloWorld.c

#include "HelloWorld.h"
#include 

JNIEXPORT void JNICALL Java_HelloWorld_print(JNIEnv *env, jobject obj)
{
  printf("Hello World!\n");
  return;
}

Compile it using cl.exe (I'm using VC++ and CL.EXE required following command line switches.)

c:\>cl -c /I"c:\Program Files\java\jdk1.7.0\include" /I"c:\Prog ram Files\java\jdk1.7.0\include\win32" HelloWorld.c

Link .obj module

c:\>link /libpath="c:\Program Files\java\jdk1.7.0\lib" HelloWorld.obj /dll
