自编译 OpenWrt 系统

😌 整理、记录一下步骤..

前置

更改源

sed -i.bak 's/\/us.archive.ubuntu.com\//\/cn.archive.ubuntu.com\//g' /etc/apt/sources.list

sudo apt update

关闭IPv6

echo 1 > /proc/sys/net/ipv6/conf//disable_ipv6

前置安装

• git subversion make automake autoconf gcc g++ binutils

make, 缺省安装

• libncurses5-dev
• libssl-dev
• gawk

前置

• GitHub(git clone https://github.com/openwrt/openwrt) 获取 OpenWrt, 更改 openWrt 目录为当前用户所有权

  # 例如:
  chown -R hocgin:hocgin openwrt

---

编译(openwrt/)

编译过程

1. make

2. ./script/feeds update -a

3. ./script/feeds install -a

4. make deconfig # 使用默认的配置

5. make menuconfig # 基于终端的一种配置方式，提供了文本模式的图形用户界面，用户可以通过光标移动来浏览所支持的各种特性。

固件配置, 可以选择编译的软件包

其余默认。

6. make kernel_config

   内核配置[开启浮点数模拟(FPU)]

7. make V=s -j<处理器数量>

8. 编译完成后，移出bin/ar71xx/OpenWrt-ImageBuilder-ar71xx-generic.Linux-x86_64.tar.bz2 文件, 并解压(tar xvf).

9. 进入(OpenWrt-ImageBuilder-ar71xx-generic.Linux-x86_64/)

10. 编译成镜像

    # 检查基础镜像
    parallels@ubuntu:~/OpenWrt/OpenWrt-ImageBuilder-ar71xx-generic.Linux-x86_64$ make image PROFILE=WNDR3700
    
    # 包含必备包`预装软件`的镜像
    parallels@ubuntu:~/OpenWrt/OpenWrt-ImageBuilder-ar71xx-generic.Linux-x86_64$ make image PROFILE=WNDR3700 PACKAGES="-dnsmasq dnsmasq-full ipset openssh-keygen openssh-server openssh-sftp-server kmod-fs-ext4 kmod-fs-ntfs kmod-fs-vfat kmod-usb2 kmod-usb-core kmod-usb-storage kmod-usb-storage-extras luci-app-firewall luci-app-samba luci-app-upnp luci luci-theme-material curl kmod-ipt-nat-extra libpcre"

11. 生成镜像(~/OpenWrt/OpenWrt-ImageBuilder-ar71xx-generic.Linux-x86_64/bin/)
