Question

Answer 1

对于可能遇到相同问题的任何人，这是 OpenCV 的正确顺序。我在 c:\Workspace\OpenCV-2.4.10-android-sdk\sdk\native\jni\OpenCVModules_armeabi_v7a.cmake 中找到了它:

foreach(_expectedTarget libtiff libjpeg libjasper libpng IlmImf tbb opencv_core opencv_androidcamera opencv_flann opencv_imgproc opencv_highgui opencv_features2d opencv_calib3d opencv_ml opencv_objdetect opencv_video opencv_contrib opencv_photo opencv_java opencv_legacy opencv_ocl opencv_stitching opencv_superres opencv_ts opencv_videostab)

当按照 foreach 中给定的顺序编译时，它们起作用了。我找不到任何可以给我正确顺序的工具，至少对于 Windows 上的 Android NDK 是这样。

所以这就是 LIBS 条目的样子:

LIBS += -L"c:/Workspace/OpenCV-2.4.10-android-sdk/sdk/native/libs/armeabi-v7a"\
        -L"c:/Workspace/OpenCV-2.4.10-android-sdk/sdk/native/3rdparty/libs/armeabi-v7a"
LIBS += \
    -llibtiff\
    -llibjpeg\
    -llibjasper\
    -llibpng\
    -lIlmImf\
    -ltbb\
    -lopencv_core\
    -lopencv_androidcamera\
    -lopencv_flann\
    -lopencv_imgproc\
    -lopencv_highgui\
    -lopencv_features2d\
    -lopencv_calib3d\
    -lopencv_ml\
    -lopencv_objdetect\
    -lopencv_video\
    -lopencv_contrib\
    -lopencv_photo\
    -lopencv_java\
    -lopencv_legacy\
    -lopencv_ocl\
    -lopencv_stitching\
    -lopencv_superres\
    -lopencv_ts\
    -lopencv_videostab
