g ++에서 std :: vectors로 이동 구문 사용하기

Question

대학의 Fedora 버전 (Linux version 3.1.9-1.fc16.x86_64 (mockbuild@x86-15.phx2.fedoraproject.org) (gcc version 4.6.2 20111027 (Red Hat 4.6.2-1) (GCC)))에서 컴파일하기 위해 VS2010의 가정용 사본에 작성된 프로그램을 얻으려고합니다.
이 프로그램은 자동 유형 및 이동 생성자와 같은 다양한 C++ 11 기능을 사용합니다.
이 모두 VS2010에는 문제가 작동하지 않습니다,하지만 난 리눅스 (g++ -g -Wall -std=c++0x -pedantic을)에 컴파일 할 때, 나는 오류의 다음과 같은 회전 수 :지도/Map.h 이후

VS2010에서 이러한 작업 벌금, 성공적으로 벡터로 임시 이동 모두, 그러나 아니다 g ++에서.
이 컴파일러의 기발한 일입니까, 아니면 내가 잘못한 것입니까? 해당 메시지를보고

Answer 1

는 지금까지 내가 오류 메시지에서 말할 수있는, 당신은 vector<MapWall>를 포함하는 Map을 복사하려고하고 MapWall가 복사 가능한 아니기 때문에이 실패합니다.

이러한 유형을 복사 할 수 있다고 가정하면 복사 생성자를 MapWall에 추가해야합니다. 사용자가 선언 한 이동 생성자는 암시 적으로 생성되지 않는다는 것을 의미합니다. (나는 VS2010이 잘못 생성 한 것 같아서 코드가 왜 작동하는지 설명 할 것입니다.)

그렇지 않은 경우 비공개 삭제 된 복사본 생성자를 Map에 추가하면 더 쉽게 불량 복사본 작업을 추적 할 수 있습니다. 그러면 복사 대상을 정확히 보여주는 오류 메시지가 표시됩니다.

Answer 2

, 나는 확신 그것은 당신의 잘못, 그리고 VS2010는

이 너무 permisive 인 :

src/Map/MapNode.h:15:3: note: Wulf::MapNode::MapNode(Wulf::MapNode&&) 
src/Map/MapNode.h:15:3: note: no known conversion for argument 1 from ‘const Wulf::MapNode’ to ‘Wulf::MapNode&&’ 
src/Map/MapNode.h:10:3: note: Wulf::MapNode::MapNode(Wulf::coord, Wulf::coord, Wulf::word, Wulf::word) 

당신이 이동 생성자, 또는 실제 생성자에 lreference의 개체를 전달하려한다는 것을 의미 .

같은 오류는 다음과 같습니다

no known conversion for argument 1 from ‘const Wulf::MapWall’ to ‘Wulf::MapWall&&’ 

몇 가지 코드를 보지 않고, 정확히 당신이 무슨 짓을했는지 알 수 없습니다.
