问题
I'm new to OpenCV and I've tried some troubleshooting with trying to get my headers to compile but keep running into Linker Errors.
Here is the code I want to run:
//Visual Studio
#include "stdafx.h"
#include <stdio.h>
#include <iostream>
#include <fstream>
#include <vector>
#include <math.h>
//LabView
//#include <NIVision.h>
//Opencv
#include <opencv/cv.h>
#include <opencv/highgui.h>
#include "opencv2/opencv.hpp"
#include "opencv2/gpu/gpu.hpp"
And Here is the Errors I'm getting:
1>------ Rebuild All started: Project: Veni_Main, Configuration: Debug Win32 ------
1> stdafx.cpp
1> Veni_Main.cpp
1>c:\opencv\build\include\opencv2\flann\logger.h(66): warning C4996: 'fopen': This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
1> c:\program files (x86)\microsoft visual studio 10.0\vc\include\stdio.h(234) : see declaration of 'fopen'
1>LINK : fatal error LNK1104: cannot open file 'opencv_haartraining_engined.lib'
========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========
I've already added the correct paths for the environmental variables and such. Please advise!
回答1:
I had the same issue while following an OpenCV tutorial. What worked for me was removing 'opencv_haartraining_engined.lib' from the list of additional dependencies for the linker.
To do this:
- right click the project
- properties
- Switch Configuration to 'All Configurations'
- Expand configuration properties
- Expand Linker
- Select Input
- Click the drop-down for 'Additional Dependencies' then click 'Edit'
- Remove the 'opencv_haartraining_engined.lib' line.
It's possible that file was removed from more recent releases.

You might want to try this link.
As written in your error message, instead of
#define _CRT_SECURE_NO_DEPRECATE
you might want to try
#define _CRT_SECURE_NO_WARNINGS

You can download the "opencv_haartraining_engined.lib" from https://code.google.com/p/huro-sift/source/browse/trunk/Development/ObjectRecognition/resources/opencv242/lib/debug/opencv_haartraining_engined.lib?r=39
and do copy/paste to "C:\Open-CV-2.4.10\opencv\build\x64\vc11\lib"
