caffe深度学习【四】编译错误：Makefile:619: recipe for target '.build_release/tools/upgrade_net_proto_binary.bin'
问题：
今天在配置caffe-SSD时，准备编译caffe遇到了整屏的错误，但是别怕，简单改一下，就可以解决问题了。
有点看不清，我直接把错误列出来：

解决方法：
修改 Makefile 文件
进入到下载的caffe目录
在 Makefile 文件中，按住crtl+f 搜索：stdc++
注意不是 Makefile.config！！！
添加 boost_regex 到 LIBRARIES += 的最后
即原来的：
LIBRARIES += boost_thread stdc++现在变成：
LIBRARIES += boost_thread stdc++ boost_regex
结果：
编译通过！！！
