Hello I am using OpenCV 2.4.3 with MinGW using Netbeans. I am testing a simple program but I am unable to compile. The error is /*********/ build/Debug/MinGW-Windows/main.o: In function main': C:\Users\Ahsan\Desktop\ImageProcessing/main.cpp:16: undefined reference tocv::imread(std::string const&, int)' build/Debug/MinGW-Windows/main.o: In function ~Mat': c:/Users/Ahsan/Desktop/opencv/build/include/opencv2/core/mat.hpp:278: undefined reference tocv::fastFree(void)' build/Debug/MinGW-Windows/main.o:c:/Users/Ahsan/Desktop/opencv/build/include/opencv2/core/mat.hpp:298: undefined reference to cv::Mat::copySize(cv::Mat const&)' build/Debug/MinGW-Windows/main.o:c:/Users/Ahsan/Desktop/opencv/build/include/opencv2/core/mat.hpp:367: undefined reference tocv::Mat::deallocate()' collect2: ld returned 1 exit status /**********/ Can you please help me. My program is
