使用 wsl+makefile+clangd编辑stm32代码环境的搭建

安装wsl环境

可以看看下面的文章安装与换源都提及，相信大家可以安装成功的

https://www.cnblogs.com/banmei-brandy/p/16218660.html

安装make、bear、clangd、arm-none-eabi-gcc、最新的构建库

sudo apt install make bear clangd gcc-arm-none-eabi libstdc++-arm-none-eabi-newlib

下载工程模板

作者是在github上浏览到的一个对std库做的一个makefile工程模板，稍加修改使用的，链接覆下

https://github.com/ertuil/stm32_template

修改makefile文档，以及使用bear生产compile_commands.json文件使用clangd进行补全以及错误分析

个人修改后的makefile模板如下

在makefile目录下使用bear生成compile_commandsr.json文件

bear -- make -j8

这时会发现在文件目录下生成了一个compile_commandsr.json文件，之后可以通过配置好的nvim进行编辑，或者通过vscode clangd插件进行编辑
