我有这个 cpp 文件:
//pkgnative_tries__native_NativeSystem.cpp
#include <pkgnative_tries__native_NativeSystem.h>
#include<iostream>
using namespace std;
extern "C"
JNIEXPORT void JNICALL Java_ClassName_MethodName
(JNIEnv *env, jobject obj, jstring javaString)
{
//Get the native string from javaString
const char *nativeString = env->GetStringUTFChars(javaString, 0);
cout << nativeString;
env->ReleaseStringUTFChars(javaString, nativeString);
}
pkgnative_tries__native_NativeSystem.h:
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class pkgnative_tries__native_NativeSystem */
#ifndef _Included_pkgnative_tries__native_NativeSystem
#define _Included_pkgnative_tries__native_NativeSystem
#ifdef __cplusplus
extern "C" {
#endif
/*
* Class: pkgnative_tries__native_NativeSystem
* Method: println
* Signature: (Ljava/lang/String;)V
*/
JNIEXPORT void JNICALL Java_pkgnative_tries__1native_NativeSystem_println
(JNIEnv *, jobject, jstring);
#ifdef __cplusplus
}
#endif
#endif
问题是,当我尝试将其编译为 DLL 时g++
,它说:
g++ -c -DBUILDING_EXAMPLE_DLL pkgnative_tries__native_NativeSystem.cpp
pkgnative_tries__native_NativeSystem.cpp:1:50: fatal error: pkgnative_tries__native_NativeSystem.h: No such file or directory
compilation terminated
有谁知道为什么?我确定这两个文件都在同一个目录中
