编译NVCaffe0.16出错-不支持gcc4.8.3-已安装4.8.5

解决：

GitHub上提问没人理啊。。╮(╯▽╰)╭

然后去另一个节点，装了4.8.5的GCC编译器，环境搭好后，竟然编译成功了，原来4.8.3和4.8.5之间就有一道墙啊~~

So，在要测试的机器上装了4.8.5 的GCC，问题解决了。。

（我不会告诉你我先装了GCC 6.2.0，结果..报错..GCC的版本竟然不能高于5..

/usr/local/cuda/include/host_config.h 

#error -- unsupported GNU version! gcc versions later than 5 are not supported!

然后还是灰溜溜的装了4.8.5...

从网上搜了一下好像是编译器的问题，现在正在准备装高版本的GCC编译器，试试看有没有用。
