opencv配置安装

opencv配置安装

1、安装方式

https://blog.csdn.net/qq_45022687/article/details/120241068

根据这个网址的配置进行安装

2、解编译

  1. mutex/thread等

    似乎因为mingw的问题,#include 等直接引入线程无法直接引用，这导致了原有代码中直接使用mutex/thread的部分需要修改

      调整mingw/bin在环境变量中的相对位置

3、文档配置

1）launch.json

{"version": "0.2.0","configurations": [{"name": "Python: Current File","type": "python","request": "launch","program": "${file}","python": "D:\\\\BasicSetting\\\\python\\\\python.exe","args": ["--source"]},{"name": "(gdb) Launch", // 配置名称，将会在启动配置的下拉菜单中显示  "type": "cppdbg", // 配置类型，这里只能为cppdbg  "request": "launch", // 请求配置类型，可以为launch（启动）或attach（附加）  "program": "${workspaceFolder}/exe/${fileBasenameNoExtension}.exe", // 将要进行调试的程序的路径  "args": [], // 程序调试时传递给程序的命令行参数，一般设为空即可  "stopAtEntry": false, // 设为true时程序将暂停在程序入口处，一般设置为false  "cwd": "${workspaceFolder}", // 调试程序时的工作目录，一般为${workspaceFolder}即代码所在目录  "environment": [],"externalConsole": false, // true则弹出终端，false会在下方terminal直接输出"MIMode": "gdb",// 这里的路径需要修改。改成自己的路径"miDebuggerPath": "D:/BasicSetting/mingw64/bin/gdb.exe","preLaunchTask": "g++", // 调试会话开始前执行的任务，一般为编译程序，c++为g++, c为gcc  "setupCommands": [{"description": "Enable pretty-printing for gdb","text": "-enable-pretty-printing","ignoreFailures": true}]}]
}

2)c_cpp_properties.json

{"configurations": [{"name": "Win32","includePath": ["${workspaceRoot}",// 以下7行需要修改 "D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++","D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/x86_64-w64-mingw32","D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/backward","D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include","D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include-fixed","D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/include","D:/BasicSetting/protoc-21.9-win64/include","D:/BasicSetting/opencv/build/x64/mingw/install/include"],"defines": ["_DEBUG","UNICODE","__GNUC__=6","__cdecl=__attribute__((__cdecl__))"],"intelliSenseMode": "msvc-x64","browse": {"limitSymbolsToIncludedHeaders": true,"databaseFilename": "","path": ["${workspaceRoot}",// 以下7行需要修改 "D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++","D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/x86_64-w64-mingw32","D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include/c++/backward","D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include","D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/include-fixed","D:/BasicSetting/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/include","D:/BasicSetting/protoc-21.9-win64/include","D:/BasicSetting/opencv/build/x64/mingw/install/include"]}}],"version": 4
