出错

查看发现是缺少了micro-ecc下的文件
于是先```idf.py build menuconfig``` 把设置中的Compatibility options中
把Include headers accross components as before IDF V4.0选项打开
重新build
报一样的错误

经过查看microecc目录发现存在makefile.mk但是源文件内容为空

返回github上查看对应项目发现micro-ecc是一个git的submodule

查询本地仓库的.gitsubmodule发现配置正确无误
根据找到的资料执行

报错

于是在本地删除了micro-ecc文件夹，尝试根据资料执行

报错

鉴于自动添加submodule的方式一直失败，选择手动添加micro-ecc仓库

接下来执行

输出

再```idf.py build
