VsCode C语言 SDL包配置 2024.9

写这篇文章的起因是，最近我需要使用 SDL 包，我懒得下载V-studio ,所以直接在VsCode 里配置C环境。我搞了好几个小时，啥都弄好了，但是一直被下面几个问题缠绕导致demo启动不了，现在我记录一下这奇葩的解决过程。所有路径都是英文。

前提条件：

配置好 C/C++ 编译器/调试器 MinGW_W64 自行百度
安装好 VsCode 里面的C++ 插件（紫色那个） C/C++ for Visual Studio Code
下载SDL2-devel-2.30.6-VC 并解压，文件夹内容如下：
创建一个空文件夹作为项目文件夹：mySdl
VsCode 打开 mySdl
配置好 .vscode 里的基本文件, 确保可以运行简单的 printf 函数

我遇到的奇葩问题：
- c 文件里无法引入 #include “SDL.h” 头文件
我试过修改他们说的配置文件：

//c_cpp_properties.json"includePath": ["${workspaceFolder}/**","${default}","你的路径\\SDL2-2.30.6\\include",  //依旧找不到头文件"你的路径\\SDL2-2.30.6\\include\\**",  //依旧找不到头文件"你的路径\\SDL2-2.30.6\\include\\",  //依旧找不到头文件],

后来我他妈直接把 SDL2-2.30.6\include 和 SDL2-2.30.6\lib\x64 两个文件夹里的文件直接复制到 mySdl 路径下：

.vscode 文件配置：
然后配置tasks.json 的 args，从命令行里链接头文件

//tasks.json"args": ["-I", //此处链接SDL头文件"${workspaceFolder}\\include", //此处链接SDL头文件"-fdiagnostics-color=always","-L",  //此处链接lib文件夹"${workspaceFolder}\\lib", //此处链接lib文件夹"-g","${file}","-o","${fileDirname}\\${fileBasenameNoExtension}.exe","-lSDL2main",  //此处链接lib文件"-lSDL2"     //此处链接lib文件],

配置之后莫名其妙的好了，但是我又遇到：
找不到 SDL2main 里的函数还是什么鬼东西
奇怪的要死，我明明已经配置好了系统环境变量 Path，我还重启了2次Vscode，一次电脑。
但就是没用，就是说找不到，于是我把环境变量直接删了。

妈了个巴子，它运行起来了

总结：
我的配置方式有些小众，总之就是把 include 使用 “-I” 引入，lib文件不需要环境变量。
以下是我的全部配置： 注意一下你的 MinGW_W64 路径即可
