이미 지난 72 시간 을에서 인터넷을 검색하는 오류를 수정에서 저를 도와주세요 감사합니다. N

지금

extern "C" 

즉, 어떠한 "둥근"인용 없어야에 "C""C" 변경 후

Answer 1

은 ""확인 : 문자열

#include <string.h> 
#include <jni.h> 

    extern "C" { 
      JNIEXPORT jstring JNICALL 
      Java_com_example_Hellojnicpp_stringFromJNI 
      (JNIEnv *env, jobject obj) 
      { 
       return env->NewStringUTF("Hello from C++ over JNI!"); 
      } 
    } 

Answer 2

extern “C” 

을 다음과 같은 오류가 진행한다. 텍스트 편집기가 직선 따옴표를 "미화"하지 않도록하십시오.
