Opencv --- I cannot use the function imread

I have a problem in opencv function. I can use 

IplImage* img = CvLoadImage("2_DeepViewOutput.png");

However I cannot use 

Mat img = imread("2_DeepViewOutput.png");

It gave me

Multiple markers at this line - Line breakpoint: Hello.cpp [line: 11] - undefined reference to `cv::imread(std::string const&, int)'

I think I have loaded the library in the path. I did not know the reason, please help me.

The problem is that you have included C header files, not C++ header files. So, your program cannot be compiled because the declaration of the cv::imread(std::string const&, int) function is not present in the C header file.

So, you have to include C++ header files. (e.g - #include "opencv2/highgui/highgui.hpp") (This link will help you)

And if you have not configured your IDE for C++, please go through this link
