caffe之mac环境下通过XCode调试C++程序
caffe log输出参考：http://blog.csdn.net/langb2014/article/details/50482150mac下用xcode开发caffe：http://coldmooon.github.io/2015/08/14/compile_caffe_cpp/
Xcode编译Undefined symbols for architecture xxx 错误总结：https://my.oschina.net/ioslighter/blog/363211
Xcode, 给项目添加framework：http://www.cnblogs.com/SeeMeFly/archive/2011/09/09/2172688.html

还没成功
问题：
LOG(ERROR) 可以正常打印信息。
LOG(INFO) 不起作用。
解决办法：
添加此句： FLAGS_alsologtostderr =1
然后先看一下是怎么加输出到日志，
#高性能矩阵计算，数值运算库
brew install openblas
#不加可能不会在/usr/local/include(bin) 中创建openblas的link,导致查找不到cblas.h的错误
brew link openblas --force
一、C++ Standard Library
二、Build Settings/ Other Linker Flags添加：-lboost_system
Undefined symbols for architecture x86_64:
"boost::system::system_category()", referenced from:
___cxx_global_var_init.2 in main.o
"boost::system::generic_category()", referenced from:

___cxx_global_var_init.1 in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
三、未解决
