Mac OSX에서 Clang 연결 오류가 발생했습니다

Question

Mac OSX 10.9.3에서 g++을 사용하여 컴파일 할 수없는 매우 기본적인 C++ 프로그램이 있습니다.

하여 Main.cpp

#include "MyClass.hpp" 

int main() { 
    MyClass::MyClass obj = MyClass::MyClass(); 
    return 0; 
} 

MyClass.hpp

class MyClass { 
public: 
    MyClass(); 
    void method(); 
private: 

}; 

MyClass.cpp를

#include "MyClass.hpp" 

using namespace MyClass; 

MyClass() { 

}; 

void method() { 

}; 

우리 나는 그것을 컴파일하려면 전자 g++ 여기

g++ main.cpp -o out 

나는 결과로 무엇을 얻을 수 있습니다 :

Undefined symbols for architecture x86_64: 
    "MyClass::MyClass()", referenced from: 
     _main in main-2750ac.o 
ld: symbol(s) not found for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

그래서 다음 g++ main.cpp -o out -v를 실행하고이를 얻을 :

내가 여기에 박히합니다.

MyClass.cpp을 컴파일하지 마십시오. 이것을 시도하십시오 :
