（二）OpenMptcpRouter - 镜像构建

1. 参考资料

参考文档：

https://github.com/Ysurac/openmptcprouter/wiki/Create-image-for-unsupported-platform
官方似乎说 6.1内核已经不再支持了
推荐使用最新的6.12内核，看官方的git历史，更新很频繁

2. 编译环境

Ubuntu 20.04，需要梯子，编译过程中会下载大量依赖的包

安装依赖

sudo apt-get install -y subversion \
  g++ \
  zlib1g-dev \
  build-essential \
  git \
  python \
  python3 \
  python3-distutils \
  libncurses5-dev \
  gawk \
  gettext \
  unzip \
  file \
  libssl-dev \
  wget \
  libelf-dev \
  ecj \
  fastjar \
  java-propose-classpath \
  uuid-dev \
  libell-dev

3. 构建树莓派`RPI4`镜像

3.1 选择使用`6.1`或`6.12`内核

我使用6.1和6.12内核均构建成功，下面将在构建6.1和6.12内核遇到的问题进行汇总

开始构建

# 6.1内核
OMR_TARGET="rpi4" OMR_FEED_SRC="master" OMR_KERNEL="6.1" ./build.sh -j1 V=s

# 6.12内核
OMR_TARGET="rpi4" OMR_FEED_SRC="master" OMR_KERNEL="6.12" ./build.sh -j1 V=s

3.2 解决 `zstd` 报错

编译 zstd 报错
错误原因：zstd 的补丁patch有问题
解决方法：替换一下这个patch
打开这个链接：https://git.infobricfleet.com/gtu/openwrt/-/tree/v24.10.0-rc1/tools/zstd，替换掉源码中的source/tools/zstd目录
然后进入到 rpi4/6.12/source目录，直接执行 make; 注意：不要再执行build.sh脚本，否则修改过的文件又会被恢复
首次构建时最好使用单线程，并输出详细的构建过程
```
$ cd rpi4/6.12/source
$ make -j1 V=s
```

3.3 解决 `clang` 和 `llvm` 版本报错

糟糕，忘了截图了
错误原因：Ubuntu 20.04上使用的clang和llvm版本为V10，需要更新到V12
安装clang-12和llvm-12
```
$ sudo apt install -y clang-12 llvm-12
```

更新后，发现实际使用的仍是旧版本，需要重建相关软链接，将其链接到更新后的 clang-12 和 llvm-12

# 由于/usr/bin/clang仍然链接到clang-10，需要重建软链接，将其链接到clang-12 和 llvm-12
$ sudo rm /usr/bin/clang
$ sudo ln -s /usr/bin/clang-12 /usr/bin/clang

# 重建clang++软链接，将其链接到clang++-12
$ sudo rm /usr/bin/clang++
$ sudo ln -s /usr/bin/clang++-12 /usr/bin/clang++

# 重建LLVM 的opt软链接，将其链接到opt-12
$ sudo rm /usr/bin/opt
$ sudo ln -s /usr/bin/opt-12 /usr/bin/opt

# 重建llvm-dis软链接，将其链接到llvm-dis-12
$ sudo rm /usr/bin/llvm-dis
$ sudo ln -s /usr/bin/llvm-dis-12 /usr/bin/llvm-dis

# 重建llvm-config软链接，将其链接到llvm-config-12
$ sudo rm /usr/bin/llvm-config
$ sudo ln -s /usr/bin/llvm-config-12 /usr/bin/llvm-config

# 再次检查clang版本
$ clang --version
Ubuntu clang version 12.0.0-3ubuntu1~20.04.5
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

# 再次检查llvm版本
$ llvm-config --version
12.0.0

重新执行 make
```
rpi4/6.12/source$ make -j1 V=s
```

3.4 解决 `util-linux` 报错

编译 util-linux 报错
错误原因：源码中缺少 util-linux 这个 package
解决方法：从openwrt源码中拷贝这个包
打开这个连接：https://git.infobricfleet.com/gtu/openwrt/-/tree/master/tools/util-linux,将整个目录都拷贝到source/tools目录下
重新执行 make
```
rpi4/6.12/source$ make -j1 V=s
```

3.5 解决编译 `mptcpd` 报错

编译 mptcpd 报错
错误原因：包含的头文件不对，如下图，只有在当前平台不支持 MPTCP 路径管理的 netlink API 时，才会包含头文件 linux/mptcp_upstream.h，实际使用的头文件是 mptcp.h，而 mptcp.h 中又缺少两个枚举类型的声明，需要修改 mptcp.h
修改 staging_dir/toolchain-x86_64_gcc-12.3.0_musl/include/linux/mptcp.h文件，添加如下两行代码

3.6 解决编译 `dnsmasq` 报错

编译 dnsmasq 报错
将 package/network/services/dnsmasq/patches/999-remove-nftset-logs.patch 这个文件中的内容全部删除即可，这个patch就是注释了一行日志，无伤大雅

3.6 编译产生的 `img` 文件

编译产生的img文件存储在build_dir目录下
```
$ find . -name "*img.gz"
```

4. 树莓派CM4启用串口

将编译好的镜像烧录到树莓派后，默认情况下串口是无法使用的，需要修改系统配置以启用串口
将只读文件系统修改为可读可写
```
# mount -o remount,rw /
```
修改/etc/inittab,在其中添加下面这行
```
ttyAMA0::askfirst:/usr/libexec/login.sh
```
重启即可
```
reboot
```

5. 聚合路由器相关设置

聚合路由器设置界面
MPTCP设置界面

6. 构建脚本`build.sh`详解

通过分析修改build.sh脚本，可以了解或实现如下功能：
- 了解为什么每次对源码进行修改后，不能重新执行build.sh脚本
- 修改默认的FEED软件源，将其替换为国内源可大大提升下载速度
- 可以只获取源码，不进行编译
- 可以定制进入系统的banner信息
- 可以设置系统运行时的软件源
- 可以不清理编译产物，加快二次编译速度
- 可以修改.config文件，启用或关闭某些内核模块
- ...
为了便于分析，我删除了此脚本中的部分无关内容
