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 in main.o
      ___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
