# 基于libclang实现C++代码链路解析

## 一、`libclang`的安装

### 1.1 Window环境下的安装
下载[LLVM for Windows](https://github.com/llvm/llvm-project/releases)，本文档我们以`LLVM 21.1.4`版本为例，如下图所示：

下载完成后，双击安装。除下图所示位置需要修改外，其余步骤一路下一步！

![LLVM-21.1.4-win64.exe_20251113_113710](assets/LLVM-21.1.4-win64.exe_20251113_113710-20251113113754-6cnrp2c.png)

安装`完成`如图所示，点击完成。

![LLVM-21.1.4-win64.exe_20251113_114153](assets/LLVM-21.1.4-win64.exe_20251113_114153-20251113114214-xwdfxss.png)

检查是否安装成功，默认安装路径：`C:\Program Files\LLVM\`

确认`libclang.dll`和头文件存在：

```shell
C:\Program Files\LLVM\bin\libclang.dll
# 头文件
C:\Program Files\LLVM\include\clang-c\
```

## 二、Graphviz的安装

### 2.1 Windows环境下的安装

下载[Graphviz](https://graphviz.org/download/#windows)，本文档我们以`graphviz-14.0.2`版本为例，如下图所示：

![局部截取_20251113_145157](assets/局部截取_20251113_145157-20251113145201-4zgtqpl.png)

下载完成后，双击安装。除下图所示位置需要修改外，其余步骤一路下一步！

![windows_10_cmake_Release_graphviz-install-14.0.2-win64.exe_20251113_151435](assets/windows_10_cmake_Release_graphviz-install-14.0.2-win64.exe_20251113_151435-20251113151453-i0wzozp.png)

## 三、Python实现

### 1、使用Python虚拟环境创建工程

本Demo基于`Python 3.13`

### 2、激活虚拟环境，并使用`pip`安装依赖

- 安装`libclang`

```log
(.venv) PS E:\workspace\CCodeParse> pip install libclang
