如何让 Visual Studio 编译具有 OpenCV 支持的应用程序?
How do I get Visual Studio to compile my application with OpenCV support?
问:
我需要编译并运行一个使用 .为此,我下载并安装了 .我确认我可以编译和运行一个Hello World终端应用程序。OpenCV
MS Visual Studio 2010
现在,我已经相应地安装并设置了编译器和链接器路径。我写了一个小示例应用程序:OpenCV
#include "stdafx.h"
#include<opencv2/opencv.hpp>
#include<iostream>
using namespace cv;
int _tmain(int argc, _TCHAR* argv[])
{
Mat img = imread("7MLS142.jpg");
namedWindow("image", WINDOW_NORMAL);
imshow("image", img);
waitKey(0);
return 0;
}
但是当我想编译并运行它时出现以下错误:

设置中的设置为我设置的位置(有一个&一个)目录并且我已经安装了“Visual Studio 2010” - 这是导致这里问题的原因吗?Additional library path
Linker
%OPENCV_DIR%\bin
setx -m OPENCV_DIR C:\Users\rideo\opencv\build\x64\vc14
vc14
vc15
更新
我现在已经安装了,设置 C:\Users\rideo\opencv\build\x64\vc15',打开了同一个项目,但仍然得到:MS Visual Studio Professional 2015

这是opencv-3.4.3-vc14_vc15.exe
答:
vc14
用于使用 .Visual studio 2015
但是您已经安装了 Visual Studio 2010
对于 VS2010,环境变量应使用 (取决于 32 位或 64 位)
setx -m OPENCV_DIR D:\OpenCV\Build\x86\vc10 (suggested for Visual Studio 2010 - 32 bit Windows)
setx -m OPENCV_DIR D:\OpenCV\Build\x64\vc10 (suggested for Visual Studio 2010 - 64 bit Windows)
以下是有关使用静态或动态库的更多指南:
下面是带有屏幕截图的详细指南,涉及在Visual Studio 2015 C++项目中使用OpenCV所需的所有必需的项目设置。
