尝试brpc来升级rpc服务，测试应用过程

照着官方文档来，不过在mac下还是有些小坑

对熟悉c++的人来说很小儿科，但对c++相对比较外行 (只知道基本语法和部分数据结构)的人，还是作不到开箱即用

首先编译
```
If you need to enable cpu/heap profilers in examples:

brew install gperftools
If you need to run tests, install and compile googletest (which is not compiled yet):

git clone https://github.com/google/googletest && cd googletest/googletest && mkdir bld && cd bld && cmake .. && make && sudo mv libgtest* /usr/lib/ && cd -
```

报错

大量的std错误

查看googletest官方信息

果然看到
```
C++ Standard Version
An environment that supports C++11 is required in order to successfully build Google Test. One way to ensure this is to specify the standard in the top-level project, for example by using the set(CMAKE_CXX_STANDARD 11) command. If this is not feasible, for example in a C project using Google Test for validation, then it can be specified by adding it to the options for cmake via the DCMAKE_CXX_FLAGS option.

```
更改
vim ../CMakeLists.txt
添加
set(CMAKE_CXX_STANDARD 11)

编译成功

==> Pouring gnu-getopt-1.1.6.high_sierra.bottle.tar.gz
==> Caveats
gnu-getopt is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have gnu-getopt first in your PATH run:
echo 'export PATH="/usr/local/opt/gnu-getopt/bin:$PATH"' >> ~/.bash_profile
