+# 1. clang-tidy使用指南
+
+   使用clang-tidy工具进行代码规范管理。
+1. 编译时实时报错；
+2. 指定自研源码检测；
+
+## 1.1. 环境搭建
+
+1. llvm使用cmake编译，cmake版本要求 3.20以上，此处使用cmake-3.27.4
+```
+// cmake源码目录：//tools/cmake-3.27.4.tar.gz
+// cmake源码安装：
+tar zxvf cmake-3.27.4.tar.gz
+cd cmake-3.27.4/
+sudo apt-get install openssl // 如果执行./bootstrap提示缺少ssl相关资源，执行此安装命令
+./bootstrap
+make
+sudo make install
+```
+2. 安装llvm
+```
+// 下载源码
+git clone https://github.com/llvm/llvm-project.git
+cd llvm-project/
+mkdir build
+cd build
+cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD="X86" -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" ../llvm
+make -j8
+find ./ -name clang-tidy // 确认编译完成
+```
+
