解决“possibly undefined macro: AC_PROG_LIBTOOL”

今天特别花1688在51buy.com上买了台同方的笔记本用于mooon的开发，先是安装了Fedora，觉得不好，想安装openSuSE，但发现安装包太大，最后仍选择了ubuntu 12.04，默认没有安装automake等工具，按提示逐一进行了安装，遇到如下这个错误时，表示libtool没有安装：

$ sh first_once.sh 

Convert ltmain.sh from the format of DOS to UNIX OK.

Convert configure.ac.in from the format of DOS to UNIX OK.

Convert Makefile.am from the format of DOS to UNIX OK.

Convert Make.rules.in from the format of DOS to UNIX OK.

configure.ac:64: error: possibly undefined macro: AC_PROG_LIBTOOL

      If this token and others are legitimate, please use m4_pattern_allow.

      See the Autoconf documentation.

autoconf ERROR

只需要执行“sudo apt-get install libtool”安装好即可解决。
