namedWindow（）导致在opencv 2.3.1中崩溃？ （Eclipse + MinGW XP，C ++） [英] namedWindow() causes crash in opencv 2.3.1? (Eclipse+MinGW on XP, C++)

问题描述

我终于设法使opencv 2.3.1与eclipse，mingw和32位XP一起使用。当我找不到这个工具链时，我会提出一个工作方法。

麻烦的是，任何在窗口中显示结果的尝试都会导致未处理的异常。图像保存不错，我能够在其上运行一个Sobel内核，所以其他一切似乎都很好。调用namedWindow时，似乎崩溃了。

我将包含libopencv_core231，libopencv_highgui231，libopencv_imgproc231和libopencv_legacy231与链接器。

这是代码：

  #include< cv.h> 
 #include< highgui.h> 
 #include< iostream> 
 
使用命名空间cv; 
 
 int main（int argc，char ** argv）
 {
 std :: cout<"Hello<< std :: endl; 
 
 //创建图像
 Mat lena，lenasobel; 
 
 //加载lena图像
 lena = imread（C：\\lena.jpeg）; 
 
 if（lena.data）
 std :: cout<File has< lena.cols<<rows and< lena.rows< ;<列。<< lena.channels（）<"channels。< std :: endl; 
 
 if（！lena.data）
 std :: cout<File Not Read。<< std :: endl; 
 
 lenasobel = lena.clone（）; 
 Sobel（lena，lenasobel，lenasobel.depth（），1,1,3）; 
 
 std :: vector< int> jpg_type; 
 jpg_type.push_back（100）; 
 jpg_type.push_back（CV_IMWRITE_JPEG_QUALITY）; 
 
 imwrite（C：\\lenaout.jpeg，lenasobel，jpg_type）; 
 
 //保存作品！ 
 
 namedWindow（lena，CV_WINDOW_AUTOSIZE）; 
 imshow（lena，lena）; 
 
 return 0; 
} 
  

有没有人有任何想法？我不知道下一步该怎么办？

解决方案

这可能是由于这个 bug 。我实际上必须设置 BUILD_TYPE = Debug ，并禁用所有SSE优化，使OpenCV能够与Eclipse + MinGW一起使用。

I've finally managed to get opencv 2.3.1 to work with eclipse, mingw and 32 bit XP. I'll put up a howto when everzthing works, as I couldn't find one for this toolchain.

The trouble is that any attempt to show the results in a window causes an unhandled exception. The images save fine, and I was able to run an Sobel kernel on them so everything else seems fine. It seems to crash when namedWindow is called.

I'm including libopencv_core231, libopencv_highgui231, libopencv_imgproc231 and libopencv_legacy231 with the linker.

Here is the code:

            #include <cv.h>
            #include <highgui.h>
            #include <iostream>

            using namespace cv;

            int main(int argc, char **argv)
            {
                std::cout<<"Hello"<<std::endl;

                //Create image
                Mat lena, lenasobel;

                //Load lena image
                lena = imread("C:\\lena.jpeg");

                if(lena.data)
                std::cout<<"File has "<<lena.cols<<" rows and "<<lena.rows<<" columns. "<<lena.channels()<<" channels."<<std::endl;

                if(!lena.data)
                std::cout<<"File Not Read."<<std::endl;

                lenasobel=lena.clone();
                Sobel(lena,lenasobel,lenasobel.depth(),1,1,3);

                std::vector<int> jpg_type;
                jpg_type.push_back(100);
                jpg_type.push_back(CV_IMWRITE_JPEG_QUALITY);

                imwrite("C:\\lenaout.jpeg",lenasobel,jpg_type);

                //Save works!

                namedWindow( "lena" , CV_WINDOW_AUTOSIZE);
                imshow( "lena" ,lena);

                return 0;
            }

Does anyone have any ideas? I'm not sure what to do next!

解决方案

This is probably due to this bug that has been hanging around. I actually had to set BUILD_TYPE=Debug and disable all SSE optimizations to get OpenCV to work with Eclipse + MinGW.
