在mac上为ios编译mono

1.下载源码到mac

2.打开终端，解压源码 tar xvf mono-VERSION.tar.gz

3.进入源码目录 cd mono-VERSION

4.配置

在mono源码目录中创建文本文件xcrun，将以下命令拷贝进去，在终端中执行./xcrun，完成之后，可以在mono_target目录中看到已经安装完成的三个目录，armv7，armv7s，sim

注意1：如果源码不是从git克隆出来，而是从官方下载的tar源码包，编译过程出现找不到route.h的情况，则可能源码中缺少这个文件，可以从git库中拷贝此文件。

注意2：如果编译过程出现cannot run test program while cross compiling 错误，可以根据提示，打开configure文件，修改对应的条件选项使跳过错误检查。参考：http://blog.csdn.net/qihuanfengyun/article/details/5385043
