带有OpenCV的Qt Android项目-tbb编译错误

我想用OpenCV创建一个Qt Android应用程序。我正在Ubuntu 12.04（64位）上使用Essentials Qt Creator和OpenCV 2.4.0 Android二进制软件包。目前，我只是创建了一个OpenCV Mat对象

但是当我编译项目时，我得到一些tbb函数的“未定义引用”错误：

> /home/kolbe/src/android-sdk-linux/OpenCV-2.4.0/libs/armeabi-v7a/libopencv_core.a(stat.cpp.o):-1: In function tbb::interface6::internal::start_for<tbb::blocked_range<int>, cv::BatchDistInvoker, tbb::auto_partitioner>::execute():
stat.cpp:-1: error: undefined reference to tbb::internal::allocate_continuation_proxy::allocate(unsigned int) const
stat.cpp:-1: error: undefined reference to tbb::internal::allocate_continuation_proxy::allocate(unsigned int) const
...

为什么OpenCV找不到tbb函数？谢谢

库的顺序对于链接很重要。尝试按以下方式重新排列行：

LIBS += \
$$ANDROID_OPENCV/libs/armeabi-v7a/libopencv_contrib.a \
$$ANDROID_OPENCV/libs/armeabi-v7a/libopencv_legacy.a \
$$ANDROID_OPENCV/libs/armeabi-v7a/libopencv_ml.a \
$$ANDROID_OPENCV/libs/armeabi-v7a/libopencv_objdetect.a \
$$ANDROID_OPENCV/libs/armeabi-v7a/libopencv_calib3d.a \

您可以尝试以下方法。。。它对我有用

将libopencv_java.so复制到QT_INSTALLDIR/5.1.1/android_armv7/lib 然后将以下内容添加到.pro LIBS+=-lopencv_java

可能重复的

LIBS += \
$$ANDROID_OPENCV/libs/armeabi-v7a/libopencv_contrib.a \
$$ANDROID_OPENCV/libs/armeabi-v7a/libopencv_legacy.a \
