linux安装emacs

emacs24.4为例

1. 更新软件依赖库，防止找不到makefile

yum update
yum install gcc* glib* gtk* ncurses* libXpm* giflib* libjpeg* libtiff* libpng* -y

2. 下载emacs

wget http://mirrors.ustc.edu.cn/gnu/emacs/emacs-24.4.tar.gz

3. 解压文件

tar -zxvf emacs-24.4.tar.gz

4. 切换到解压目录下生成makefile（cd emacs-24.4)

./configure

5. 编译并安装

make && make install

6. 配置环境变量，在 /etc/profile最后加上如下代码

PATH=$PATH:/usr/local/bin 
export PATH

7. 使配置立即生效

source /etc/profile

8. 验证是否安装成功

emacs --version
