无法在编译期间链接opencv库

this tutorial ,一切都很成功,但我编写了一个画圆的示例程序,

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
using namespace cv;

int main( )
{    
  // Create black empty images
  Mat image = Mat::zeros( 400, 400, CV_8UC3 );

  // Draw a line 
  line( image, Point( 15, 20 ), Point( 70, 50), Scalar( 110, 220, 0 ),  2, 8 );
  imshow("Image",image);

  waitKey( 0 );
  return(0);
}

我弄错了。根据 this question ,我必须在编译程序时链接导入的库。但是在我的 MinGW/lib 文件夹没有这样的文件 opencv_core.a 或 opencv_highgui.a ,但我有 libopencv_core400.dll.a libopencv_highgui400.dll.a

所以,如果我试着选择 -lopencv_core 和 -lopencv_highgui

D:\Programs\CppProgramming>g++ -lopencv_core -lopencv_highgui -std=c++11 OpenCVTest.cpp
C:/Program Files (x86)/CodeBlocks/MinGW/bin/../lib/gcc/mingw32/5.1.0/../../../../mingw32/bin/ld.exe: cannot find -lopencv_core
C:/Program Files (x86)/CodeBlocks/MinGW/bin/../lib/gcc/mingw32/5.1.0/../../../../mingw32/bin/ld.exe: cannot find -lopencv_highgui
collect2.exe: error: ld returned 1 exit status

-llibopencv_core400 以及- llibopencv_highgui400

D:\Programs\CppProgramming>g++ -llibopencv_core400 -llibopencv_highgui400 -std=c++11 OpenCVTest.cpp
