在安装emacs软件前，需要先安装一些依赖包，然后在下载emacs的软件包解压，再安装即可，具体步骤如下：
1、需要下载的依赖包如下：
yum -y groupinstall "Development Tools"
yum -y install gtk+-devel gtk2-devel
yum -y install libXpm-devel
yum -y install libpng-devel
yum -y install giflib-devel
yum -y install libtiff-devel libjpeg-devel
yum -y install ncurses-devel www.2cto.com
yum -y install gpm-devel dbus-devel dbus-glib-devel dbus-python
yum -y install GConf2-devel pkgconfig
yum -y install libXft-devel
2、到如下链接下载emacs的安装包并解压
http://ftp.gnu.org/pub/gnu/emacs/
#解压文件
tar xvf emacs-24.2.tar.gz
3、安装emacs
cd emacs-24.2
./configure --prefix=/usr/local --with-x-toolkit=gtk
make && make install
在安装过程中遇到如下错误：
xsettings.o: In function `something_changed_gsettingsCB‘:
/root/Downloads/emacs-24.2/src/xsettings.c:216: undefined reference to `g_settings_get_value‘
/root/Downloads/emacs-24.2/src/xsettings.c:231: undefined reference to `g_settings_get_value‘
/root/Downloads/emacs-24.2/src/xsettings.c:245: undefined reference to `g_settings_get_value‘

collect2: ld returned 1 exit status
make[1]: *** [temacs] Error 1
make[1]: Leaving directory `/root/Downloads/emacs-24.2/src‘
make: *** [src] Error 2
解决办法如下：
make distclean
./configure --without-gsettings
make && make install
安装成功后出现如下提示：
make[1]: Leaving directory `/root/Downloads/emacs-24.2/leim‘
cd lib-src; make maybe-blessmail \
MAKE=‘make‘ archlibdir=‘/usr/local/libexec/emacs/24.2/i686-pc-linux-gnu‘
make[1]: Entering directory `/root/Downloads/emacs-24.2/lib-src‘
make[1]: Nothing to be done for `maybe-blessmail‘.
make[1]: Leaving directory `/root/Downloads/emacs-24.2/lib-src‘
在终端中输入emacs，即可打开软件
