mex 함수에서 OpenCV 사용 : 컴파일 후 오류

matlab에서 개발 한 프로젝트에서 작업하고 있지만 C++ 및 OpenCV를 사용해야했습니다. 내 작업을 프로젝트와 통합하려면 mex-files를 사용해야합니다. 그래서 컴퓨터와 gcc에 Matlab 2013을 설치했습니다. 4.4. opencv에 맞는 컴파일러와 옵션을 설정하기 위해 ~/.matlab/R2013a/mexopts.sh 파일을 수정했습니다. 이 MEX와 MATLAB에서 컴파일 출력 내가이 mxFunction ('path_to_my_file')처럼 mxFunction를 사용하려고하면mex 함수에서 OpenCV 사용 : 컴파일 후 오류

는 수 이 문제를 해결하는 데 도움이됩니까?

PS : 난 당신이 MEX-파일로 OpenCV의 코드를 포함하는 C/C++ 파일을 컴파일하려는 경우 난 강력하게 당신이 mexOpenCV 대신 mex를의 사용하는 것이 좋습니다 우분투 14.04 및 OpenCV의 2.4.8

모든 opencv 라이브러리 (.so 파일)를 MEX 파일이있는 폴더로 복사하십시오. – chappjc

또는 공유 라이브러리가있는 폴더를'PATH' 환경 변수에 추가하십시오 :'setenv ('PATH', [/ usr/local/lib 'pathsep() getenv ('PATH ')])' MATLAB을 시작하기 전에 쉘에서'PATH') – Amro
