proto 튜토리얼을 사용할 때 연결 오류가 발생했습니다.

Question

아파치와 함께 우분투에서 C++을 사용하고 있습니다. 다음과 같이

나는 addressbook.proto 파일을 컴파일 :

#include "addressbook.pb.h" 

을해야한다고 다음과 같이

protoc -I=/home/workspace/rtb/src/ --cpp_out=/home/workspace/rtb/src/ /home/workspace/rtb/src/addressbook.proto 

나는 다음 내 C++ 코드로 출력 헤더 파일을 포함. 권리?

빌드 할 때 ... 목록에 너무 긴 목록이 표시됩니다. 아래는 마지막 몇 줄입니다. 내가 뭘 놓치고 있니? C++에서 proto 버퍼를 사용하려면 어떻게해야합니까?

Answer 1

코드를 프로토콜 버퍼 라이브러리에 연결해야합니다. 가장 필요한 플래그는
-l protobuf입니다.
