을 다음과 같이

#include <iostream> 
#include <string> 
#include <boost\filesystem.hpp> 

namespace bf = boost::filesystem; 

bf::path o("C:\\mir"); 
bf::path p("C:\\mir\\dir\\beer.txt"); 
bf::path r("C:\\test"); 

auto pp = std::mismatch(o.begin(), o.end(), p.begin()); 
r.append(pp.second, p.end()); // this line causes compiler error 

내가 컴파일러 오류가 다음과 같이 boost::filesystem를 사용하여 새 경로를 생성하기 위해 노력하고있어 원인

내 코드가 잘못되어 어떻게 해결할 수 있습니까? 미리 감사드립니다.

Answer 1

path :: append는 일련의 문자를 예상하며 경로 범위를 제공했습니다. 그것은 자신의에 의해 각 요소를 추가해야합니다

auto pp = std::mismatch(o.begin(), o.end(), p.begin()); 
for(auto iter = pp.second; iter != p.end(); ++iter) 
    r /= *iter; 

불행하게도 부스트 : : 파일 시스템 경로는 경로를 arithmetics위한 인터페이스를 제공하지 않습니다.
