Question

我编译了这个简单的opencv代码：

#include "opencv2/core/core.hpp"        
#include "opencv2/highgui/highgui.hpp"  
#include <boost/random.hpp>
#include <ctime>
#include <time.h>
#include <stdlib.h>
#include <math.h>
#include <iostream>

/*Compile using 

g++ -I /usr/local/boost CreateShares.cpp -o createShares `pkg-config --cflags --libs opencv` 

*/
using namespace cv;

class CreateShares
{
private:
    cv::Mat CoreImage;

    cv::Mat CoreImageR;
    cv::Mat CoreImageG;
    cv::Mat CoreImageB; 

    cv::Mat share0;
    cv::Mat share1;
    cv::Mat share2;
    cv::Mat share3;

public:
    CreateShares();
    CreateShares(std::string path);

    void showCoreImage();
    void showCoreImageR();
    void showCoreImageG();
    void showCoreImageB();

};

CreateShares::CreateShares()
{

}

CreateShares::CreateShares(std::string path)
{
    CoreImage = cv::imread(path, 1);

    if (CoreImage.empty())
    {
        std::cout<<"Could not read image !"<<std::endl;
        return;
    }
    std::vector<cv::Mat> temp_mat_vector; 
    cv::split(CoreImage, temp_mat_vector);

    //CoreImageB = (temp_mat_vector[0]).clone();
    temp_mat_vector[0].copyTo(CoreImageB);
    temp_mat_vector[1].copyTo(CoreImageB);
    temp_mat_vector[2].copyTo(CoreImageB);


}

void CreateShares::showCoreImage()
{
    cv::namedWindow("Core Image", WINDOW_AUTOSIZE);
    cv::imshow("Core Image", CoreImage);
}

void CreateShares::showCoreImageR()
{
    cv::namedWindow("Core Image R", WINDOW_AUTOSIZE);
    cv::imshow("Core Image R", CoreImageR);
}

void CreateShares::showCoreImageG()
{
    cv::namedWindow("Core Image G", WINDOW_AUTOSIZE);
    cv::imshow("Core Image G", CoreImageG);
}

void CreateShares::showCoreImageB()
{
    cv::namedWindow("Core Image B", WINDOW_AUTOSIZE);
    cv::imshow("Core Image B", CoreImageB);
}

int main()
{
    std::string path = "/home/r/l33t/Secret Sharing/nature.jpg";

    CreateShares* cs = new CreateShares(path);
    cs->showCoreImage();

    return 0;
}

然后我继续运行它，但我得到了这个奇怪的错误：

r@r-HP-Mini-110:~/l33t/Secret Sharing$ g++ -g -I /usr/local/boost CreateShares.cpp -o createShares `pkg-config --cflags --libs opencv`
r@r-HP-Mini-110:~/l33t/Secret Sharing$ ./createShares

  what():  /build/buildd/opencv-2.3.1/modules/core/src/array.cpp:2482: error: (-206) Unrecognized or unsupported array type in function cvGetMat

我将gdb输出粘贴到错误中以帮助您分析：

任何想法在这里可能是错的？我的代码有什么问题或opencv有问题，或者我没有在某处包含某些opencv路径或opencv未正确安装？我没有想法。请帮我！
