Emacs 24.3出来好久了，但是在Debian 7里还是Emacs 23的版本.
以下是安装步骤（9步）：
sudo aptitude install git-core libxaw7-dev libxpm-dev libpng12-dev libtiff5-dev libgif-dev libjpeg8-dev libgtk2.0-dev libncurses5-dev autoconf automake texinfo sudo apt-get build-dep emacs git clone git://git.savannah.gnu.org/emacs.git
cd emacs/ git checkout emacs-24.3 git checkout -b custom_branch ./autogen.sh ./configure --prefix=/opt/emacs24 make --jobs=2 sudo make install
按这个顺序安装就好了，大概半个小时到一个小时的样子。
安装好后把emacs添加到PATH里，打开~/.bashrc 文件，在最后添加：
export PATH=$PATH:/opt/emacs24/bin
保存后：
source .bashrc
这样在终端里就可以直接输入 emacs 就可以启动了。
经常按alt+F2 打开应用程序窗口，但是这里面输入emacs却不行，办法是把emacs软链接到 /usr/bin 目录里：
cd /usr/bin ln -s /opt/emacs24/bin/emacs emacs
打完收工！
2010.10.03 更新：
以上通过git的方式今天用起来好慢！只好换一种方式。
一、安装编译所需包 2014.10.03 10:43～10：45
sudo apt-get install libxaw7-dev libxpm-dev libpng12-dev libtiff5-dev libgif-dev libjpeg8-dev libgtk2.0-dev libncurses5-dev autoconf automake texinfo

Yes后开始下载安装这些包，结束时有此提示：
在处理时有错误发生： /var/cache/apt/archives/libfontconfig1-dev_2.9.0-7.1_amd64.deb E: Sub-process /usr/bin/dpkg returned an error code (1)
google了下，好像是下载文件不完整造成的，删除该包，重新下载安装：
sudo rm /var/cache/apt/archives/libfontconfig1-dev_2.9.0-7.1_amd64.deb sudo apt-get install libfontconfig1-dev
二、下载emacs压缩包
从这里下载：http://mirror.bjtu.edu.cn/gnu/emacs/
文件叫 emacs-24.3.tar.gz 有50M，下载在Download目录里。
$ cd ~/Download $ tar zxvf emacs-24.3.tar.gz # 解压后有170M。
三、编译前配置 11：13～11：14
在Download目录里新建一个目录放置编译时生成的文件，以免所有的文件都在解压后的 emacs-24.3 目录里。
$ mkdir compileemacs # 放置编译后生成的文件 $ cd compileemacs $ ../emacs-24.3/configure --prefix=/opt/emacs

四、编译 11:21~11:29
$ make
五、安装 11：47～11：48
sudo make install
安装成功后添加到环境变量中：
export PATH=$PATH:/opt/emacs24/bin
软链接到 /usr/bin 目录里：
cd /usr/bin ln -s /opt/emacs24/bin/emacs emacs ls -l emacs lrwxrwxrwx 1 root root 22 10月 3 11:54 emacs -> /opt/emacs24/bin/emacs
