emacs等安装在～/INSTALL目录下，在～下新建一个INSTALL目录。
1. emacs-24.1.tar.gz ecb-2.40.tar.gz cscope-15.7a.tar.bz2下载到～/Download目录下
2. 依次执行:
tar -zxvf emacs-24.1.tar.gz
mv emacs-24.1 ../INSTALL
tar -zxvf ecb-2.40.tar.gz
mv ecb-2.40 ../INSTALL
tar -jxvf cscope-15.7a.tar.bz2
mv cscope-15.7a ../INSTALL
ecb、cscope 无需make安装。
3. 进入emacs-24.1目录：cd ~/INSTALL/emacs-24.1
依次执行：
./configure --prefix=$PWD (到当前目录下)
第一次执行肯定缺少一些包，按照提示，在Synaptic Package Manager里面搜索装上。（这一步一定要保证Synaptic Package Manager 的源最新可用，否则很可能找不到包）
多次执行configure命令并添加提示需要的包。
所有包添加完毕后：
依次执行：
make
make install
之后在emacs-24.1目录下bin文件夹里会有emacs可执行文件生成。
4. 运行emacs后， 点options随便保存一下设置，左下角状态会显示已创建~/.emacs文件
修改.emacs文件为：
(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
)
(custom-set-faces
;; custom-set-faces was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.

5. 大功告成，重新运行emacs，尝试使用cscope、ecb等。
