新版的sphinx支持latex需要修改两个文件了：

1
2

/usr/local/lib/python2.7/dist-packages/sphinx/templates/latex/content.tex_t 
/usr/local/lib/python2.7/dist-packages/sphinx/writers/latex.py

第一个模板文件中找到位置加上2行CJK相关的配置。

\usepackage{multirow}
\usepackage{eqparbox}
\usepackage{CJKutf8}
<!-- snip -->
\end{CJK}
\end{document}

第二个latex.py中需要改一下，在begin{document}后面增加一行。

BEGIN_DOC = r'''
\begin{document}
\begin{CJK}{UTF8}{gbsn}

• Download “Third party app GPL sources” from WD website. There is mksapkg tool for build WD App package
• Make “App” (Use any of GPL “sources” as base).
• apkg.sign & apkg.xml automatically generated by mksapkg tool, based on apkg.rc data
• Hmm… If you found something usefyl - add it to init.sh in any app (This file executed firs after reboot / while OS boot)
• For unpack compiled apkg (app) use 7zip (He can automatically skip header info).

• About fil structure inside app:

• apkg.rc - Main file, info about this app

• before_apkg.sh - Script, run before apkg install
• preinst.sh - Preinstall script, exec before install.sh, but after before_apkg.sh
• init.sh - exec every time, when OS start.
• Install.sh & remove.sh - install/remove scripts
• start.sh & stop.sh - For control app (exec when user change “enable this app” checkbox in web gui)
• web/desc.xml - localisation file / app info (For web gui)
• web/app_name.png - app icon for web gui
• web/index.html - App web page for control.

闲来无事试着给WD Mycloud编编软件试试。

编译dpdk

在x86_64 linux ubuntu 16.04环境下：

1

make install T=x86_64-native-linuxapp-gcc

如果需要查看详细输出，可以运行

1

make install T=x86_64-native-linuxapp-gcc V=1

手里一台机器突然死机，重启后grub失灵了，于是费了一番周折恢复grub2。
先用光盘进入系统，然后打开terminal。

sudo su -
mkdir /mnt
mount /dev/sda4 /mnt
mount /dev/sda2 /mnt/boot
mount -t proc proc /mnt/proc
mount --bind /sys /mnt/sys
mount --bind /dev /mnt/dev
chroot /mnt

进入后，首先安装grub2时发现域名不能解析，设置了一下 /etc/resolv.conf，比照外面环境设置即可。

1

echo "nameserver 127.0.1.1" > /dev/resolv.conf

然后执行

1
2
3

apt install grub2
parted /dev/sda set 1 bios_grub on
grub-install --target=i386-pc /dev/sda

执行正常没有报错。重启后进入了久违的grub界面。但是又有了新问题，进不去系统了。卡在了systemd的dev-disk服务。
systemd的该服务超时，进入维护模式，后来想到是不是/etc/fstab由于分区的修改导致uuid发生了变化，所以修改了/etc/fstab，不使用uuid了，直接用/dev/sdaX来标示分区。
重启，解决问题！回到了我的系统。
