路線圖

• [x] 所需MSYS包安裝
• [x] VSCode插件和環(huán)境配置
• [x] GCC平臺(tái)編譯
• [ ] MSVC CL平臺(tái)編譯

目的

1. 在Windows平臺(tái)中繼續(xù)使用VS Code編寫調(diào)試C/C++程序
2. 在Windows平臺(tái)中兼顧gcc的項(xiàng)目編譯，減少跨平臺(tái)錯(cuò)誤
3. 避免使用Visual Studio的相應(yīng)鍵位绢彤，使用VS Code的高效編輯

準(zhǔn)備

1. MSYS2(推薦) / MinGW
2. VSCode
3. VSCode 插件 (C/C++, Cmake, Cmake-tools)

路徑與環(huán)境變量設(shè)置

1. MSYS_DIR=C:\msys64
2. MINGW64_DIR=C:\msys64\mingw64
3. 加入Path: %MSYS_DIR%\usr\bin, %MINGW64_DIR%\bin

MSYS安裝配置

1. 安裝MSYS2

2. 修改MSYS的Server配置粱甫，分別在對(duì)應(yīng)文件開(kāi)頭加入如下語(yǔ)句

   # in mirrorlist.msys
   Server = http://mirrors.ustc.edu.cn/msys2/msys/$arch 
   # in mirrorlist.mingw64
   Server = http://mirrors.ustc.edu.cn/msys2/mingw/x86_64
   # in mirrorlist.mingw32
   Server = http://mirrors.ustc.edu.cn/msys2/mingw/i686
   

3. 從MSYS庫(kù)安裝msys/make

4. 安裝MinGW庫(kù)安裝gcc滔韵、gdb、cmake舅列、make和opencv祟峦、boost(可選)等相關(guān)組件庫(kù)

VSCode配置

1. 建立項(xiàng)目文件夾
2. Ctrl+Shift+P -> C/Cpp: Edit Configuration..., 輸入如下配置: (若是gcc位置不同，需要自行修改compilerPath和includePath)

   {
        "configurations": [
            {
                "name": "clang",
                "includePath": [
                    "${workspaceFolder}/**",
                    "C:/msys64/mingw64/include"
                ],
                "defines": [
                    "_DEBUG",
                    "UNICODE",
                    "_UNICODE"
                ],
                "compilerPath": "c:/msys64/mingw64/bin/gcc.exe", 
                "cStandard": "c11",
                "cppStandard": "c++17",
                "intelliSenseMode": "clang-x64"
            }
        ],
        "version": 4
    }
   

3. 編寫C/C++文件
4. 配置當(dāng)前Workspace中的C/C++ IntelliSense設(shè)置：

   {
        "cmake.configureOnOpen": true,
        "cmake.generator": "MSYS Makefiles",
        "C_Cpp.default.configurationProvider": "vector-of-bool.cmake-tools"
    }
   

5. 在項(xiàng)目根目錄下建立CMakeLists.txt,配置項(xiàng)目的主要編譯內(nèi)容(參見(jiàn)文件夾中的三個(gè)例子)
6. 在對(duì)應(yīng)的自定義包目錄下建立CMakeLists.txt,將對(duì)應(yīng)的子目錄聲明加入對(duì)應(yīng)的模塊
7. 在根目錄CMakeLists.txt使用Ctrl+Shift+P -> CMake: Configure來(lái)配置項(xiàng)目環(huán)境變量
8. Ctrl+Shift+P -> CMake: Build
9. 到對(duì)應(yīng)的build目錄下找到對(duì)應(yīng)的可執(zhí)行文件
10. 配置調(diào)試launch.json,參考模板如下:

    {
        // Use IntelliSense to learn about possible attributes.
        // Hover to view descriptions of existing attributes.
        // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
        "version": "0.2.0",
        "configurations": [
            {
                "name": "(gdb) Launch",
                "type": "cppdbg",
                "request": "launch",
                "program": "${workspaceFolder}/build/cmtst.exe",
                "args": [],
                "stopAtEntry": false,
                "cwd": "${workspaceFolder}",
                "environment": [],
                "externalConsole": true,
                "MIMode": "gdb",
                "miDebuggerPath": "C:/msys64/mingw64/bin/gdb.exe",
                "setupCommands": [
                    {
                        "description": "Enable pretty-printing for gdb",
                        "text": "-enable-pretty-printing",
                        "ignoreFailures": true
                    }
                ]
            }
        ]
    }
