ESP-C3入门20. CentOS开发环境及Jenkins流水线

一、准备环境

• CentOS8
• 已经正常安装Jenkins

二、升级 cmake

cmake 升到 3.16以上。

cmake --version
# 安装 g++
sudo yum install gcc-c++
export CXX=g++# 安装 CMake 的依赖项
sudo yum install -y openssl-devel# 下载 CMake 源码并进行编译安装
wget https://github.com/Kitware/CMake/releases/download/v3.21.1/cmake-3.21.1.tar.gz
tar -zxvf cmake-3.21.1.tar.gz
cd cmake-3.21.1
./bootstrap
make
sudo make install

三、升级 bash

bash要升到 4 以上。

cd /opt
wget -v http://ftp.gnu.org/gnu/bash/bash-5.1.16.tar.gz
tar zxvf bash-5.1.16.tar.gz
cd bash-5.1.16/
./configuremake install
mv /bin/bash /bin/bash.bak && ln -s /usr/local/bin/bash /bin/bash

四、安装IDF编译工具链

1. 替换源

git clone https://gitee.com/EspressifSystems/esp-gitee-tools.git
cd esp-gitee-tools/
./jihu-mirror.sh  set

# 依赖准备
sudo yum -y update && sudo yum install git wget flex bison gperf  cmake ninja-build ccache dfu-util libusbx

在这里遇到个问题，提示：
Public key for jenkins-2.401.2-1.1.noarch.rpm is not installed，
意思是系统中缺少 Jenkins 软件包的公钥，因此无法验证软件包的真实性。
执行下面操作：

cd /opt
wget -O jenkins.rpm https://pkg.jenkins.io/redhat-stable/jenkins-2.401.2-1.1.noarch.rpm --no-check-certificate
sudo yum localinstall jenkins.rpm

2. 安装python3.8

ESP-IDF 需要python3.7以上版本，如果yum仓库版本比较低，则需要手动下载安装。

cd /opt
wget https://www.python.org/ftp/python/3.8.16/Python-3.8.16.tgz
tar -zxvf Python-3.8.16.tgz
ls
cd Python-3.8.16./configure --prefix=/opt/Python-3.8.16 --with-openssl=/usr/local/openssl
make 
make install
rm -rf /usr/bin/pip3 /usr/bin/python3
ln -s /usr/local/bin/pip3.8  /usr/bin/pip3
ln -s /usr/local/bin/python3.8  /usr/bin/python3

2. 获取 ESP-IDF

mkdir -p /opt/esp
cd /opt/esp
git clone -b v5.1 --recursive https://github.com/espressif/esp-idf.git

3. 安装 ESP-IDF

cd /opt/esp/esp-idf
# 提高下载速度
export IDF_GITHUB_ASSETS="dl.espressif.com/github_assets"
./install.sh esp32,esp32s2,esp32c2,esp32c3
. ./export.sh

五、流水线设置

Jenkinsfile脚本 ：

pipeline{agent anyenvironment {IDF_PATH = "/opt/esp/esp-idf" // 替换为您的 ESP-IDF 安装路径IDF_PYTHON_ENV = "/usr/bin/python3" // 替换为您的 Python 虚拟环境路径（可选）}parameters{choice(name: 'ENV', choices: 'intranet\ntest\n', description: '部署环境')choice(name: 'CHIPSET', choices: 'esp32c3\nesp32c2\n', description: '芯片')choice(name: 'VERSION_TYPE', choices: '最新版本\n指定版本\n', description: '版本指定方式')string(name: 'VERSION', description: '版本', defaultValue: '1')choice(name: 'LOG', choices: '打印\n屏蔽\n', description: '是否打印日志')}stages{stage('Build') {steps {echo 'Building'script {echo "start"sh "/usr/local/bin/python3 /opt/esp/esp-idf/tools/idf_tools.py install"sh "cd $IDF_PATH && . /opt/esp/esp-idf/export.sh" // 激活 ESP-IDF 环境和 Python 虚拟环境if (params.VERSION_TYPE == '最新版本') {// 从 constants.h 文件中获取 MODULE_SOFT_VERSION 的值def versionHex = sh(returnStdout: true,script: "cat main/config/include/constants.h | grep 'MODULE_SOFT_VERSION' | awk '{print \$3}'").trim()// 将十六进制转换为十进制def versionDecimal = versionHex.toLong(16)// 赋值给 VERSIONparams.VERSION = versionDecimal.toString()}sh "idf.py set-target ${params.CHIPSET}"sh "idf.py build" // 在工作目录下运行 idf.py build 命令进行编译String calcPath = '/www/server/tomcat/webapps/upload';// 上传到指定路径sh "scp ${env.WORKSPACE}/build/whr_wifi_esp32.bin root@${host['test']}:${calcPath}/${params.VERSION}"sh "scp ${env.WORKSPACE}/build/partition_table/partition-table.bin root@${host['test']}:${calcPath}/${params.VERSION}"// 这里可以根据需要打印下载地址echo "烧写命令"echo "/opt/esp/esp-idf/components/esptool_py/esptool/esptool.py -p (PORT) -b 460800 --before default_reset --after hard_reset --chip ${params.CHIPSET}  write_flash --flash_mode dio --flash_size 4MB --flash_freq 60m 0x0 build/bootloader/bootloader.bin 0x8000 build/partition_table/partition-table.bin 0x10000 build/project.bin"echo "或运行 'idf.py -p (PORT) flash'"}}}}
}

六、问题处理

1. 找不到 GLIBCXX_3.4.20

    Run Build Command(s):/usr/bin/ninja-build cmTC_a92c3 && [1/2] Building CXX object CMakeFiles/cmTC_a92c3.dir/testCXXCompiler.cxx.objFAILED: CMakeFiles/cmTC_a92c3.dir/testCXXCompiler.cxx.obj /root/.espressif/tools/riscv32-esp-elf/esp-12.2.0_20230208/riscv32-esp-elf/bin/riscv32-esp-elf-g++   -march=rv32imc_zicsr_zifencei -o CMakeFiles/cmTC_a92c3.dir/testCXXCompiler.cxx.obj -c /var/lib/jenkins/workspace/whr-wifi-esp32/build/CMakeFiles/CMakeTmp/testCXXCompiler.cxx/root/.espressif/tools/riscv32-esp-elf/esp-12.2.0_20230208/riscv32-esp-elf/bin/../libexec/gcc/riscv32-esp-elf/12.2.0/cc1plus: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /root/.espressif/tools/riscv32-esp-elf/esp-12.2.0_20230208/riscv32-esp-elf/bin/../libexec/gcc/riscv32-esp-elf/12.2.0/cc1plus)

执行：

strings /usr/lib64/libstdc++.so.6 | grep GLIBCXX

拷一个 libstdc++.so.6.0.25到 /usr/lib64，执行：

ln -s libstdc++.so.6.0.25 libstdc++.so.6
ls -l libstdc++.so.6
strings libstdc++.so.6 | grep GLIBC

2. 提示"/lib64/libc.so.6: version GLIBC_2.18' not found (required by /lib64/libstdc++.so.6)"

curl -O http://ftp.gnu.org/gnu/glibc/glibc-2.18.tar.gz
tar zxf glibc-2.18.tar.gz 
cd glibc-2.18/
mkdir build
cd build/
../configure --prefix=/usr
make -j2
make install
