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+ 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.
安装libgtk开发包：
$ sudo apt-get install libgtk2.0-dev
libXpm libjpeg libgif/libungif libtiff gnutls were not found
configure: error: The following required libraries were not found:
libXpm libjpeg libgif/libungif libtiff gnutls
Maybe some development libraries/packages are missing?
If you don't want to link with them give
--with-xpm=no --with-jpeg=no --with-gif=no --with-tiff=no --with-gnutls=no
as options to configure
