segmentation fault when imread is active [closed]
Hi,
I am having a problem that is really driving me crazy. I installed opencv and cannot find out what is causing the problem. I copied sample code from the tutorials to test my installation and I get a segfault whenever I start the program.
I reduced the code to identify the cause of the problem:
#include <stdio.h>
#include <iostream>
#include "opencv2/core/core.hpp"
#include "opencv2/features2d/features2d.hpp"
#include "opencv2/highgui/highgui.hpp"
//#include "opencv2/nonfree/features2d.hpp"
#include "opencv2/nonfree/nonfree.hpp"
using namespace cv;
void readme();
/** @function main */
int main( )
{
std::cout << "hello!!!" << std::endl;
Mat img_1;
img_1 = imread("eagle.jpg");
int minHessian = 400;
SurfFeatureDetector detector( minHessian );
// std::vector<KeyPoint> keypoints_1, keypoints_2;
// detector.detect( img_1, keypoints_1 );
return 0;
}
imread seems to be the culprit. If I exclude imread("eagle.jpg") it works fine. But if I put it into the code I get a segfault once I execute the code - even before "hello!!!" is printet.
This is where the debugger stops and gives me the segfault - if anybody can read anything from that. -> (0x7fffd492cdfc <+0x0000> lock incl (%rax))
I tried to install different versions of opencv without success.
I am using Ubuntu 14.04 with Qt Creator 3.0.1 and currently opencv 2.8.3
I greatly appreciate any help!
Cheers
there is no opencv 2.8.3 (that is most probably your cmake version)
