环境

ubuntu2004
SDK目录：~/SDK/esp/esp-idf

官方参考给的文档是 ~/esp/esp-idf

流程概述

安装依赖
下载SDK
下载管理工具
2.1 修改下载源
2.2 下载、管理toolchain
2.3 下载、管理子库
2.4 etc
复制工程验证环境

一、安装依赖

略

二、下载SDK、管理工具

1. 管理工具下载

repo：https://gitee.com/EspressifSystems/esp-gitee-tools.git

mkdir -p ~/SDK/esp
cd ~/SDK
git clone https://gitee.com/EspressifSystems/esp-gitee-tools.git

2. 下载SDK

repo：https://gitee.com/EspressifSystems/esp-idf.git

cd ~/SDK
git clone https://gitee.com/EspressifSystems/esp-idf.git、
mv esp-idf/ esp/

要特定分支就切一下版本

三、安装toolchain、更新子库、配置SDK环境

1. 替换下载源，安装虚拟环境等等

cd ~/SDK/esp-gitee-tools
export EGT_PATH=$(pwd)
echo $EGT_PATHcd ~/SDK/esp/esp-idf
$EGT_PATH/install.sh

参考log如下：

等待一会儿，让他自己下自己装

2. 更新子库

$EGT_PATH/submodule-update.sh

参考log：

3. 配置SDK环境

每次新shell中更新环境变量：在shell rc中价格别称，添加esp-ief/export.sh环境

vi ~/.bashrc
# Add ： 
alias get_idf='. $HOME/SDK/esp/esp-idf/export.sh'

更新shell环境，验证esp环境配置

source ~/.bashrc
get_idf

参考log：

Setting IDF_PATH to 'xxxxxxx/SDK/esp/esp-idf'

Checking "python3.8" ...

...
Done! You can now compile ESP-IDF projects.
Go to the project directory and run:idf.py build

四、复制例程验证环境

例程：~/SDK/esp/esp-idf/examples/get-started/hello_world

创个文件夹，把例程复制过来，更新下SDK环境，开始编译

mkdir -p ~/tmp/esp
cp -rf ~/SDK/esp/esp-idf/examples/get-started/hello_world  ~/tmp/esp/
cd ~/tmp/esp/hello_world/get_idf
idf.py build
//idf.py set-target esp32s3   // 看个人需求

编译不报错即可。

参考log：

问题汇总

1. CMake 版本低

设置编译目标时，提示cmake版本低
Make 3.16 or higher is required. You are running version 3.10.2

fix：更新cmake 版本

下载源码、编译、安装、替换链接、校验
URL： https://cmake.org/files/
下载文件：https://cmake.org/files/v3.28/cmake-3.28.1.tar.gz
解压、编译、安装

cd ~/tmp/
wget https://cmake.org/files/v3.22/cmake-3.28.1.tar.gz  // 看个人需求变更版本
tar -zxvf cmake-3.28.1.tar.gz
cd cmake-3.28.1/
# chmod 777 configure
./configure			// 需要g++编译器，注意安装
make
sudo make install
# 更新链接
sudo update-alternatives --install /usr/bin/cmake cmake /usr/local/bin/cmake 1 --force
