Qt-problems encountered in learning

     1. [modules\core\CMakeFiles\opencv_core.dir\build.make:1494: modules/core/CMakeFiles/opencv_core.dir/vs appears during CMake compilation

      Solution: Uncheck OPENCV/OPENCV_ENABLE_ALLOCATOR_STATS in CMake

     2.modules\python3\CMakeFiles\opencv_python3.dir\build.make:82: modules/python3/CMakeFiles/opencv_python3.dir/__/src2/cv2.cpp.obj]

         Solution:

3. error: 'vector' is not a member of cv

The program compiled correctly under opencv2.4.11 appears error: 'vector' is not a member of cv under opencv3.2　

Reason: Before opencv 3.0, std::vector was used directly in core.hpp,

　　　　So cv::vector is essentially std::vector

　　　　However, it seems to be removed after version 3.0, so the compilation error

Solution: Add vector to the cv namespace in the code:　　　　

ｎａｍｅspace cv
{
      using std::vector;   
}
