WLS2Linux 子系统(二)

WLS2Linux 子系统编译 Openwrt

上一篇文章中讲解 windows 安装 WSL2Linux 子系统的简单安装过程。如今有了 WSL 子系统可以完成很多以前不能完成的事，例如编译源代码、转换音视频、转换文档格式(pdf 转 word，word 转 md，word 转 html)，定制私有 OpenWRT 路由器等。说到这个系统比较陌生，提到路由器生活中处处可见，二者联系—路由器基于openwrt 开发。
此篇文章详解如何从源码编译 OpenWRT 文件系统。

提示：WSL2Linux 编译 Openwrt，下一篇 WSL2Linux 编译 uboot。

1. 编译OpenWRT 准备
- wsl2 install library
- 获取 openwrt 源码

- a) 配置编译选项
- b) 编译固件
- c) 刷机

1. 编译OpenWRT 准备

wsl2 install library

sudo apt update
sudo apt-get install build-essential subversion libncurses5-dev zlib1g-dev gawk gcc-multilib flex git-core gettext libssl-dev unzip python -y

获取 openwrt 源码

获取代码尽量在 WSL 根目录下, 否则被win10访问权限被篡改

# openwrt source
# https://git.openwrt/openwrt/openwrt.git
# https://github/openwrt/openwrt.git
git clone https://git.openwrt/openwrt/openwrt.git
# 因网络异常导致下载失败，重新下载即可
git checkout -t origin/openwrt-21.02
# git end of EOF

2. 开启 OpenWRT 编译踩坑

a) 配置编译选项

cd ~/openwrt
./scripts/feeds update -a #更新组件
./scripts/feeds install -a #安装组件
make menuconfig -j1 V=99

看到编译配置界面，根据自己设备型号配置相关属性。

文件夹 files/etc/config 创建 network 与 wireless 网卡配置文件。

# network config
config wifi-device 'radio0'
       option type 'mac80211'
       option channel '36'
       option hwmode '11a'
       option path 'platform/soc/fe300000.mmcnr/mmc_host/mmc1/mmc1:0001/mmc1:00
01:1'
       option htmode 'VHT40'

config wifi-iface 'default_radio0'
        option device 'radio0'
        option mode 'ap'
        option encryption 'none'
        option ssid 'RPI4'
        option network 'lan'

# wireless config
config wifi-device 'radio0'
       option type 'mac80211'
       option channel '36'
       option hwmode '11a'
       option path 'platform/soc/fe300000.mmcnr/mmc_host/mmc1/mmc1:0001/mmc1:00
01:1'
       option htmode 'VHT40'

config wifi-iface 'default_radio0'
        option device 'radio0'
        option mode 'ap'
        option encryption 'none'
        option ssid 'RPI4'
        option network 'lan'

b) 编译固件

开机相关代码包下载

make download -j4 V=s

火力全开编译

make -j12 V=99

编译完成生成固件几种固件

ls bin/targets/bcm27xx/bcm2711/openwrt-bcm27xx-bcm2711-rpi-4*    
bin/targets/bcm27xx/bcm2711/openwrt-bcm27xx-bcm2711-rpi-4-ext4-factory.img.gz
bin/targets/bcm27xx/bcm2711/openwrt-bcm27xx-bcm2711-rpi-4-ext4-sysupgrade.img.gz
bin/targets/bcm27xx/bcm2711/openwrt-bcm27xx-bcm2711-rpi-4-squashfs-factory.img.gz
bin/targets/bcm27xx/bcm2711/openwrt-bcm27xx-bcm2711-rpi-4-squashfs-sysupgrade.img.gz

#切换系统环境变量再执行编译命令

source /etc/environment

编译过程出错误

使用 root 权限编译错误提示

you should not run configure as root (set FORCE_UNSAFE_CONFIGURE=1 in environment to bypass this check

方法一：强制在不安全模式下编译

make FORCE_UNSAFE_CONFIGURE=1 -j1 V=s

方法二： 保存刚在配置文件，改用普通用户重新下载代码初始化刚刚的配置文件继续编译

libsoncpp-dev missing

fatal error: json/json.h: No such file or directory

安装相关库既可以解决

sudo apt-get install libjsoncpp-dev
sudo ln -s /usr/include/jsoncpp/json/ /usr/include/json

如需重新编译可选择如下几种方式：
make clean -j4 #清除 bin
make dirclean -j4 #清除 toolchain bin
make distclean -4 #清除 config feed package 等文件

c) 刷机

编译完成生成固件路径

ls `~/openwrt/bin/targets/bcm27xx/bcm2711/`
bin/targets/bcm27xx/bcm2711/openwrt-bcm27xx-bcm2711-rpi-4-ext4-factory.img.gz
bin/targets/bcm27xx/bcm2711/openwrt-bcm27xx-bcm2711-rpi-4-ext4-sysupgrade.img.gz
bin/targets/bcm27xx/bcm2711/openwrt-bcm27xx-bcm2711-rpi-4-squashfs-factory.img.gz
bin/targets/bcm27xx/bcm2711/openwrt-bcm27xx-bcm2711-rpi-4-squashfs-sysupgrade.img.gz

选 ext4 格式镜像文件，制作成 sd 卡启动；上TF卡开机测试
login IP： 192.168.1.1
login user: root
login passwd: password

Tips:
想单独编译某个插件，然后手动安装；编译后生成文件路径

ls ~/openwrt/bin/packages/aarch64_cortex-a72/packages/
Packages                                              libexpat_2.2.10-1_aarch64_cortex-a72.ipk
Packages.gz                                           libgnutls_3.7.1-1_aarch64_cortex-a72.ipk
Packages.manifest                                     libtasn1_4.16.0-1_aarch64_cortex-a72.ipk
Packages.sig                                          libtirpc_1.3.2-1_aarch64_cortex-a72.ipk
aria2_1.35.0-4_aarch64_cortex-a72.ipk                 liburing_0.7-1_aarch64_cortex-a72.ipk
attr_2.4.48-2_aarch64_cortex-a72.ipk                  netatop_3.1-1_aarch64_cortex-a72.ipk
