OpenCv在Visual Studio中未解决外部符号错误 [英] OpenCv unresolved external symbol error in Visual Studio

问题描述

我已链接到我想要使用的库，并将头文件添加到我的项目中。并且代码在红色波浪线中没有显示任何错误，但是当我尝试运行它时，它会给我以下错误：

I have linked to the libraries I want to use and added the header files to my project. And the code doesn't show any errors in red squiggle but when I try to run it, it gives me the following error:

Error   1   error LNK2001: unresolved external symbol _cvDestroyWindow  C:\Users\Jos\documents\visual studio 2010\Projects\ocv\ocv\opcv.obj ocv
Error   2   error LNK2001: unresolved external symbol _cvWaitKey    C:\Users\Jos\documents\visual studio 2010\Projects\ocv\ocv\opcv.obj ocv
Error   3   error LNK2001: unresolved external symbol _cvNamedWindow    C:\Users\Jos\documents\visual studio 2010\Projects\ocv\ocv\opcv.obj ocv
Error   4   error LNK2001: unresolved external symbol _cvLoadImage  C:\Users\Jos\documents\visual studio 2010\Projects\ocv\ocv\opcv.obj ocv
Error   5   error LNK2001: unresolved external symbol _cvShowImage  C:\Users\Jos\documents\visual studio 2010\Projects\ocv\ocv\opcv.obj ocv
Error   6   error LNK2001: unresolved external symbol _cvReleaseImage   C:\Users\Jos\documents\visual studio 2010\Projects\ocv\ocv\opcv.obj ocv
Error   7   error LNK1120: 6 unresolved externals   C:\Users\Jos\documents\visual studio 2010\Projects\ocv\Release\ocv.exe  ocv

以下是代码：

#include "highgui.h"

int main(int argc, char **argv) {
    IplImage* img = cvLoadImage(argv[1],CV_LOAD_IMAGE_UNCHANGED);
    cvNamedWindow("Example1",CV_WINDOW_AUTOSIZE);
    cvShowImage("Example1",img);
    cvWaitKey(0);
    cvReleaseImage(&img);
    cvDestroyWindow("Example1");
}   

推荐答案

好吧它终于有效了。我的电脑是 64位系统。但该项目在 Win32 平台上运行。所以我将其更改为 x64 并从 Win32 复制设置。

Ok it finally works. My PC is a 64-bit system. But the project was running on Win32 platform. So I changed it to x64 and copied settings from Win32.
