Step1：在Windows 10或者11的应用商店里面，搜索UBUNTU并安装，我安装的是18.04版本；
Step 2：在Windows开始菜单中，找到Ubuntu并打开，在命令行中进行升级：
sudo apt update
sudo apt install build-essential ccache ecj fastjar file g++ gawk \ gettext git java-propose-classpath libelf-dev libncurses5-dev \ libncursesw5-dev libssl-dev python python2.7-dev python3 unzip wget \ python3-distutils python3-setuptools python3-dev rsync subversion \ swig time xsltproc zlib1g-dev
Step 3：下载源码
git clone https://github.com/openwrt/openwrt.git
如果速度慢，先下载压缩包，再解压 wget -c https://github.com/openwrt/openwrt/archive/refs/heads/main.zip unzip main.zip cd openwrt-main/ git init git add . git remote add origin https://github.com/openwrt/openwrt.git git remote update git pull
若遇到问题：configure: error: you should not run configure as root
解决办法：切换到root用户执行：export set FORCE_UNSAFE_CONFIGURE=1
若遇到问题：fatal: unable to access ‘https://github.com/openwrt/openwrt.git/‘: gnutls_handshake() failed: The TLS connection was non-properly terminated. error: Could not fetch origin
解决办法，在命令行执行： git config –global –unset https.https://github.com.proxy && git config –global –unset http.https://github.com.proxy
Step 4：切换分支 //查看所有分支 git branch -a //可以利用tag切换 git tag git checkout v23.05.0 也可以直接利用分支名 sudo git checkout remotes/origin/openwrt-18.06
Step 5：编译前准备 sudo ./scripts/feeds update -a && ./scripts/feeds install -a
Step 6：build
make j=1
//如果OPENWRT WEB页面打不开，如何升级固件？
运行make,编译之后把生成的固件，利用winscp或者运行命令拷贝到机器：scp openwrt-ramips-xxx-squashfs-sysupgrade.bin [email protected]:/tmp/，使用sysupgrade命令升级sysupgrade /tmp/openwrt-ramips-xxx-squashfs-sysupgrade.bin
