如果你因为某些问题不想安装微软的 Visual Studio，但又必须要在 Windows 实体机上构建 Dandelion（Windows 应该是大多数人常用的系统），可以参考这篇教程，使用正确姿势搭建环境，避免出现奇怪问题。

使用 Visual Studio 构建的几个好处：\n
- 安装时是图形化界面，较直接，一下子就安装好了
- 原生编译器，减少 Windows 系统下可能出现的问题。依赖库检测操作系统不会出错，减少出错概率
- 编译速度比较快
\n
使用 mingw-w64 构建的几个好处：\n
- 大概比 Visual Studio 占用硬盘少一些，而且是便携软件，方便安装和迁移
- 与现代 Linux 系统的编译器、命令等一致，有助于学习 Linux
- 是自由软件，不和微软的 Visual Studio 绑定
\n

首先，要获取最新的 mingw-w64 工具链 (GCC14 / Clang18)。推荐的方式是使用 msys2，不可以使用诸如 Dev-C++ 或 Code::Blocks 里面自带的编译器，那些软件太老了，编译器版本太老，一定会遇到问题。获取步骤如下

访问 msys2 官网，点击 Download the installer: msys2-x86_64-xxxx.exe 下载最新安装包
按照官网的教程安装到某磁盘根目录下
打开 msys2 终端，推荐采用 clang64 环境\n
- 简单说，该环境采用 clang 编译器编译 windows 原生程序，打开的终端是 bash，这是一个类似 Linux 的环境，cmd/PowerShell 不能直接访问
\n
在环境中安装一些需要的软件包\n
- 运行 pacman -S git 安装 git
- 运行 pacboy -S toolchain:p 安装 clang 工具链
- 运行 pacboy -S cmake:p ninja:p 安装构建工具 CMake 和 ninja，其中 ninja 和 make 功能相同，可替换为 make
\n

其次，再使用 git clone 下载 dandelion 代码，checkout 到 v1.1.0 版本（或静态库对应的版本），并参考文档将静态库放置好，因为我们用的是 clang，静态库也要选择带 clang 的版本。

最后，参照 Linux 版本构建过程使用 cmake 构建，应该不需要其他操作。没有意外的话，应该可以编译成功。

关于如何使用 VS Code 调试 Clang64 环境编译的程序，以及如何添加 Clang64 环境终端，网上有很多教程，不再赘述。例如 CodeLLDB 扩展
