使用 OpenCV 修复混合 STL 实现

Question

问题

我正在尝试启动 OpenCV 和运行，但我运行遇到了与 this guy and this guy 相同的问题 - 我在尝试构建时遇到 linker 错误具有 C++ 接口的项目，但项目构建具有 C 接口。

第二个link，答案是"You're mixing different implementations of STL. VC10 (for OpenCV) and STLPort (for your code)."

如何确定我只使用 VC10？（或更高版本）

C风格（项目构建成功）

我正在使用 Visual Studio 2012 和 OpenCV 3.0

int main( int argc, char** argv )
{
    char* filename = "input.tif";  
    IplImage *img0;

    if( (img0 = cvLoadImage(filename,-1)) == 0 )
       return 0;

    cvNamedWindow( "image", 0 );
    cvShowImage( "image", img0 );
    cvWaitKey(0);  
    cvDestroyWindow("image");
    cvReleaseImage(&img0);
}

C++ 风格（项目不构建）

int main( int argc, char** argv ) {

    Mat image;
    const string &filename = "input.tif";
    image = imread(filename, IMREAD_COLOR); // Read the file

    if(! image.data ) // Check for invalid input
    {
        std::cout << "Could not open or find the image" << std::endl ;
        return -1;
    }

    namedWindow( "Display window", WINDOW_AUTOSIZE ); // Create a window for display.
    imshow( "Display window", image ); // Show our image inside it.
}

错误：

Answer 1

根据聊天中的讨论，事实证明 OP 链接的是 OpenCV 2.4.10 而不是 OpenCV 3.0。

通过更正链接库，问题已解决。
