本人安装环境为centos7，其他linux版本也大同小异，可参考操作。
1. 下载emacs-25.3.tar.gz到centos，用tar –vxzf 命令解压；
2. 进入解压后的目录，命令：cd emacs-25.3/
3. 使用./configure命令进行配置（可以设定路径）；
由于我安装的是带图形界面的，在进行这一步时，报如下错误：
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.
意思就是缺少图形界面的支持库，如果不想在图形界面下使用Emacs，可以使用./configure –without-x命令执行（看自己需求，我就只想在命令行使用，还专门修改了启动配置为在非图形界面启动），当然很多人还是想使用图形界面的，那么就需要安装相应的支持库了，报错的提示是安装Gtk+ 或者 Motif，我们安装其中一个即可。
执行命令：yum install gtk3*
然后再接着执行：./configure
发现又报如下错误：
configure: error: The following required libraries were not found:
libXpm libjpeg libgif/libungif libtiff
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
as options to configure
这还是缺少相应库支持的缘故，执行以下命令：
yum install libXpm libXpm-devel libjpeg libjpeg-devel libgif libgif-devel libungif libungif-devel libtiff libtiff-devel
然后再接着执行：./configure
发现又报如下错误：
configure: error: The required function ‘tputs’ was not found in any library.
The following libraries were tried (in order):
libtinfo, libncurses, libterminfo, libtermcap, libcurses
Please try installing whichever of these libraries is most appropriate
for your system, together with its header files.
For example, a libncurses-dev(el) or similar package.
继续安装支持库，执行以下命令：yum install ncurses-devel
然后再接着执行：./configure
此刻，没有报错信息的出现，用ls命令查看后我们看到了期待已久的Makefile文件，接着执行make和make install命令，静静的等着安装完成。
