本文包括基本的VS Code安装、C++环境配置以及OpenCV配置全过程,以及如何解决在配置过程中会遇到的问题。
官网下载:Visual Studio Code
双击.exe文件开始安装,同意此协议,点击下一步:
选择安装路径,点击下一步:
点击下一步:
根据图中提示勾选,点击下一步:
点击安装:
安装扩展:
官网下载:MinGW-w64离线包下载地址
官网下载:CMake
官网下载:OpenCV
安装完后,可以在环境变量的用户变量的Path里查看到VS Code,说明配置完成
解压MinGW-w64压缩包,将该文件夹的bin路径添加到环境变量的系统变量中:
Win+R,cmd调出控制台,检查MinGW-w64是否安装成功,若成功则如下图所示:
将CMake安装包解压,文件夹如图所示:
将该文件夹下的bin文件路径添加到环境变量的系统变量中:
Win+R,cmd调出控制台,检查CMake是否安装成功,若成功则如下图所示:
安装完OpenCV后,在 build\x64 路径下新建一个文件夹(可自起,这里是 MinGW )
进入D:\cmake-3.29.4-windows-x86_64\bin :
打开cmake-gui,选择OpenCV的源文件路径和MakeFiles保存路径(即之前新建的MinGW):
点击Configure,弹窗配置如下,点击Next:
选择前面安装的D:/mingw64/bin文件夹下的gcc.exe和g++.exe,点击Finsh:
-->耐心等待中。。。
执行过程中消息框会出现一堆红色信息,最后显示Configure done,是正常的。显示Configure done后,勾选BUILD_ opencv_world、WITH_ OPENGL和BUILD EXAMPLES,不勾选WITH_IPP、WITH_MSMF和ENABLE_PRECOMPILED_HEADERS (如果有的话),CPU_ DISPATCH选空。再次点击Configure
-->耐心等待中。。。
这次执行完后仍有错误如下:
由于网络问题(最好用梯子),仍然会有文件没有成功下载,这个时候需要手动下载它们。在自创建的MinGW下的CMakeDownloadLog.txt文件中列出了所有丢失文件的下载链接,比如:
https://raw.githubusercontent.com/opencv/opencv_3rdparty/4d348507d156ec797a88a887cfa7f9129a35afac/ffmpeg/opencv_videoio_ffmpeg.dll
一个个访问这些链接,下载后放到OpenCV源文件里.cache的相应子文件夹中替代原缓存文件(下载的文件重命名为相应地缓存文件名并删除原缓存文件)。
这样从头到尾下载CMakeDownloadLog.txt中列出的所有丢失文件,之后,再次点击Configure,出现configure down之后查看CMakeDownloadLog.txt文件,成功了显示下图:
之后点击Generate,显示Generate Done。
使用 cmake 时要求安装 python3(版本没有限制,比2高就行),并且python 必须配好了环境变量。
cmd到MakeFiles所在文件夹(如何cmd),执行如下命令:
mingw32-make -j 8
如果报错可查阅编译报错解答,如果编译成功则执行如下命令完成装载:
mingw32-make install
将D:\opencv\build\x64\MinGW\bin加到环境变量的系统变量中:

下载安装包和配置文件时最好挂上梯子,不然要么下载速度慢,要么下载失败
注意要下载安装Python3
