GNU Autotools (autoconf, automake, libtool, etc.) 自动化编译 (1) 简单示例
0. 操作平台: Linux
1. 软件包安装(Debian)
yes | sudo apt-get install gcc make autoconf automake libtool2. 从一个例子谈起。
2.0 完整拷贝如下代码直接在终端执行或者保存为auto-example.sh，添加执行权限执行。或者参考2.1~2.5逐步执行。

echo "ERROR: $@"
exit 1
}

===========================================3. 一般项目并不是简单的一个.c文件。通常包括多个（嵌套的）目录。并且需要执行差异化的编译和安装，下一篇文章示范如何在一个实际项目中应用autotools。
