QNativeImage:无法连接到共享内存段。

I saw there is one same thread: OpenCv Error in C Wrapper for imread: QNativeImage: Unable to attach to shared memory segment That thread was posted about 4 months ago. No any answer. So I re-post one.

我看到有一个相同的线程:在C包装中为imread的OpenCv错误:QNativeImage:无法连接到4个月前发布的共享内存段。没有任何答案。所以我重新邮寄一个。

I ran this code on eclipse luna on ubuntu14.04.

我在ubuntu14.04上运行了eclipse luna代码。

#include <iostream>

#include <opencv2/opencv.hpp>

using namespace std;
using namespace cv;

int main(int argc, char* argv[])
{
    Mat img = imread("/home/tqjustc/Pictures/2.jpg", CV_LOAD_IMAGE_COLOR);
    imshow("opencvtest", img);
    waitKey(0);
    return 0;
}

But there is an error.

但是有一个错误。
