最近在使用基于ARM Cortex-A9内核的飞思卡尔i.MX6Q四核处理器开发一款产品，在ubuntu 12.04上编译LTIB时遇到了找不到zlib的问题（在此之前已经安装了必须的各种库文件）。
错误信息如下：
=============================
[email protected]:~/imx6/L3.0.35_4.1.0_130816_source/source/ltib$ ./ltib
ltib cannot be run because one or more of the host packages needed to run it
are either missing or out of date or not in ltib‘s standard path. Please
install/upgrade these packages on your host. If you have your own utilities
in non-standard paths, please add an entry into the .ltibrc file for example:
%path_std
/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/X11R6/bin:/my/own/exes

=============================
问题原因：在用ubuntu12.04编译LTIB时候，需要安装脚本patch-ltib-ubuntu12.04.sh。
解决办法：
Script which patches the ltib folder on Ubuntu 12.04.
Steps:
$ cp patch-ltib-ubuntu12.04.sh <your ltib folder>
$ cd <your ltib folder>
$ chmod +x patch-ltib-ubuntu12.04.sh
$ ./patch-ltib-ubuntu12.04.sh
脚本下载：patch-ltib-ubuntu12.04.sh
