OpenCV 라이브러리를 연결하는 순서는 무엇입니까?

Question

VLC 응용 프로그램 용 모듈 구현에 OpenCV 라이브러리를 사용하고 있습니다.

나는 함수 cvSaveImage을 사용하려면,하지만 난 많은 오류를 얻을 :

나는 Android.mk 파일의 변수 이름 LOCAL_LDLIBS에서 OpenCV의 라이브러리를 연결해야합니다.

LOCAL_LDLIBS := -L$(VLC_CONTRIB)/lib \ 
    -L/home/virginia/workspace/OpenCV-2.4.5-android-sdk/sdk/native/3rdparty/libs/armeabi-v7a/ \ 
    -L/home/virginia/workspace/OpenCV-2.4.5-android-sdk/sdk/native/libs/armeabi-v7a/ \

나는 /home/virginia/workspace/OpenCV-2.4.5-android-sdk/sdk/native/3rdparty/libs/armeabi-v7a/에있는 라이브러리를 연결해야한다고 생각 : libIlmImf.a liblibjasper.a liblibjpeg.a liblibpng.a liblibtiff.a

그러나 나는 그들을 연결하는 순서를 모릅니다.

제발, 어떤 도움이 필요해! 정말 고마워!

Answer 1

나는 대답을 제공하는 링크 here 제시 믿습니다; 자세한 내용은 네이티브 C/C++ 섹션 # 4을 확인하십시오.

희망이 있습니다.

Answer 2

CMake를 사용하는 사람들에게는 아마도 어리석은 것처럼 보일지 모르겠지만 make를 사용하는 사람들에게는 make가 사용하지 않기 때문에 유용합니다.

opencv.pc 파일의 경로를 찾고 pkg-config를 호출하면 필요한 모든 것을 g ++/clang ++에 대한 호출로 출력 할 수 있습니다. 위에서 언급했듯이 pkg-config 바이너리를 호출하고 opencv.pc 파일을 전달하면 라이브러리 순서가 지정됩니다. 물론 opencv.pc 파일을 직접 사용하는 것이 좋습니다. 내 메이크 파일의 예를 들어

,이 날 여기를 얻기 위해 ChronoTrigger에 사람, 감사를하는 데 도움이

OPENCVINCPKG=$(OPENCVLIBPATH)/pkgconfig/opencv.pc 
g++ `pkg-config --cflags --libs $(OPENCVINCPKG)` myClient.cpp -o myClient 

희망.
