我想用 OpenCV 创建一个 Qt Android 应用程序。我在 Ubuntu 12.04（64 位）上使用 Necessitas Qt Creator 和 OpenCV 2.4.0 Android 二进制包。目前我只是创建了一个 OpenCV Mat 对象。
但是当我编译项目时，我得到了一些 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
...
我在我的 *.pro / qmake 文件中包含了 OpenCV 库（也是 libtbb.a）：

为什么 OpenCV 找不到 tbb 函数？谢谢！
