configure: error: You seem to be running X, but no X development libraries
were found. You should install the relevant development files for X
and for the toolkit you want, such as Gtk+, Lesstif or Motif. Also make
sure you have development files for image handling, i.e.
tiff, gif, jpeg, png and xpm.
If you are sure you want Emacs compiled without X window support, pass
--without-x
to configure.

打開終端，切換到root權限，進入/mnt目錄，執行命令：

新建目錄：mkdir shared
