本文主要介绍如何使用 MSYS + VSCode 在 windows 上搭建 C/C++ 开发环境

1. 安装和配置 MSYS2

官网下载并安装

启动脚本 msys.bat

1	@C:\msys64\msys2_shell.cmd -ucrt64 -defterm -no-start -full-path -here

换镜像源

1	sed -i "s#https\?://mirror.msys2.org/#https://mirrors.tuna.tsinghua.edu.cn/msys2/#g" /etc/pacman.d/mirrorlist*

安装编译器和调试器

1	pacman -S mingw-w64-ucrt-x86_64-gcc mingw-w64-ucrt-x86_64-gdb

2. 安装 VSCode 和配置

官网下载
安装 C/C++ 插件
以下是在 user settings.json 中配置

设置 C_Cpp 编译器路径

1	"C_Cpp.default.compilerPath": "C:\\msys64\\ucrt64\\bin\\gcc.exe"

设置默认终端为 MSYS2

"terminal.integrated.defaultProfile.windows": "MSYS2",
"terminal.integrated.profiles.windows": {               
"MSYS2": { 
        "path": [ "C:\\Library\\Command\\msys.bat" ],
        "args": [ "" ],
        "icon": "terminal-cmd"
    },
},

3. 在 VSCode 中调试程序

创建 launch.json

主要设置 program 和 miDebuggerPath

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) 启动",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/helloworld/a.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "C:\\msys64\\ucrt64\\bin\\gdb.exe",
            "setupCommands": [
            ]
        }
    ]
}

4. 基于第三方库开发

示例

安装 SDL2

1	pacman -S mingw-w64-ucrt-x86_64-SDL2 pkg-config

demo.c

#include <SDL2/SDL.h>
#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>

int main(int argc, char *argv[])
{
    SDL_Window *window = SDL_CreateWindow("demo", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 640, 480, SDL_WINDOW_SHOWN);
    SDL_Renderer *renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);
    bool quit = false;
    SDL_Event event;

    SDL_SetRenderDrawColor(renderer, 255, 255, 255, 255);
    while (!quit) {
        while (SDL_PollEvent(&event)) {
            switch (event.type) {
            case SDL_QUIT:
                quit = true;
                break;
            case SDL_MOUSEMOTION:
                if(SDL_GetMouseState(NULL, NULL) &SDL_BUTTON(1))
                    SDL_RenderDrawPoint(renderer, event.motion.x, event.motion.y);
                break;
            }
        }

        SDL_RenderPresent(renderer);
        SDL_Delay(1000 / 60);
    }
    SDL_DestroyWindow(window);
    SDL_DestroyRenderer(renderer);
    return 0;
}

编译

1	gcc demo.c `pkg-config SDL2 --cflags --libs --static` -static
