什么是carotene_o4t,为什么在Android上使用opencv和Qt编译程序时会出现问题？

我正在使用Qt编写一个Android应用程序,使用opencv.我设置了所有内容,以便我的应用程序无需opencv即可正常运行.但是,在我包含opencv 3.2(通过下载最新的sdk并设置库路径)之后,编译失败了数百个未定义的引用错误,所有这些都涉及到carotene_o4t.

C:/opencv/OpenCV-android-sdk/sdk/native/libs/armeabi-v7a/libopencv_core.a(arithm.cpp.o):arithm.cpp:function cv::hal::cmp8u(unsigned char const*, unsigned int, unsigned char const*, unsigned int, unsigned char*, unsigned int, int, int, void*): error: undefined reference to 'carotene_o4t::isSupportedConfiguration()'
C:/opencv/OpenCV-android-sdk/sdk/native/libs/armeabi-v7a/libopencv_core.a(arithm.cpp.o):arithm.cpp:function cv::hal::cmp8u(unsigned char const*, unsigned int, unsigned char const*, unsigned int, unsigned char*, unsigned int, int, int, void*): error: undefined reference to 'carotene_o4t::cmpGE(carotene_o4t::Size2D const&, unsigned char const*, int, unsigned char const*, int, unsigned char*, int)'
C:/opencv/OpenCV-android-sdk/sdk/native/libs/armeabi-v7a/libopencv_core.a(arithm.cpp.o):arithm.cpp:function cv::hal::cmp8u(unsigned char const*, unsigned int, unsigned char const*, unsigned int, unsigned char*, unsigned int, int, int, void*): error: undefined reference to 'carotene_o4t::cmpEQ(carotene_o4t::Size2D const&, unsigned char const*, int, unsigned char const*, int, unsigned char*, int)'

... 等等.

什么是carotene_o4t,我该如何解决这个问题？搜索这些消息后,Google将返回零结果.

项目文件如下所示:

路径本身似乎是正确的,因为如果我在代码中不包含opencv.hpp,它就会运行得很好.另一方面,项目文件中的错误路径会阻止构建它.

你需要链接libtegra_hal.

它包含在3rdparty文件夹中: sdk/native/3rdparty/libs/armeabi/libtegra_hal.a
