'm facing a problem with implementing SURf using Mat because of heap, so I tried to use iplimage. I used the code of this guy SURF using iplimage I've got errors:

unresolved external symbol _cvExtractSURF unresolved external symbol _cvSURFParams

I added these

#include "opencv2/nonfree/features2d.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/nonfree/nonfree.hpp"
#include <opencv2/legacy/legacy.hpp>

with cv::initModule_nonfree(); in main but it didnt work. does anyone know what is the problem ?

You are trying to execute C-API code using the C++ include headers. That will never work. I suggest leaving those IplImages and C-API. Show us your non working C++ and Mat code and we will help you out there with problems. The C-API is depricated and will disappear soon!

this link contains a code for real time surf using mat https://github.com/doczhivago/rtObjectRecognition/blob/master/main.cpp

it gives me heap corruption exception or memory location exception

did you check that csv ? is it working fine with the code ? and did you check the path of your images ?
