遇到很多坑，慢慢记录，这里使用的centos 6.7，环境搭建路漫漫，一定要根据错误提示来解决问题

1. 下载源码 https://github.com/Unity-Technologies/mono/tree/unity-5.3

2. 安装环境 64bit

yum install autoconf

yum install libtool

yumintall –y gcc-c++

yum install bison

yum install –y gettext

yum install glib2-devel.i686 #注意此处安装的是glib开发包

yum installperl #安装perl

yum install git #安装git，后面编译的脚本会用到git去下载

yum install glibc-devel.i686

yum install libstdc++.i686

yum install zlib-devel.i686
