되지 않은 외부 기호를 OpenCV의

Question

내가 OpenCV의와 프로젝트를 구축하기 위해 노력하고있어,하지만 난 다음 오류 받고 있어요와 비주얼 스튜디오 2010에서 프로젝트를 빌드 할 때 : 나는 cMake가 파일을 사용하고

을 프로젝트를 생성하면 그 내용은 다음과 같습니다.

모든 openCV 메소드가 오류를 일으키는 것으로 보입니다. 왜 그런가? 모든 라이브러리/헤더 파일을 프로젝트에 올바르게 가져 왔지만 여전히 이러한 문제가 발생한다고 생각합니다. 어떤 도움이나 올바른 방향으로 나를 가리키면 좋을 것입니다. 감사!

OpenCV Build on Visual Studio LINK error :

Answer 1

난 당신이 RatSLAM C++ 라이브러리를 사용한다고 가정 위에 표시된 오류에서

, 내가 너무 VS 2010에서 컴파일하는 동안 같은 오류가 있었다 나는 아래 링크의 도움으로 그것을 해결할 수 있었다

위의 링크는 OpenCV 라이브러리 폴더의 opencv_core246.lib 및 opencv_highgui246.lib와 같이 특정 lib 파일을 구성해야한다고 말합니다. 링크는이를 구성하는 방법을 설명하는 튜토리얼을 안내 :

도움이 되었기를 바랍니다.
