安装gflags:
gflags是google开源的一套命令行参数解析工具，支持从环境变量和配置文件读取参数：

git clone https://github.com/gflags/gflags.git
cd gflags
git checkout -b 2.2 v2.2.2
cmake -DCMAKE_INSTALL_PREFIX=/usr/local -DBUILD_SHARED_LIBS=ON -DGFLAGS_NAMESPACE=google -G "Unix Makefiles" .
make && sudo make install
sudo ldconfig
sudo ln -s /usr/local/lib/libgflags.so.2.2 /lib64

CentOS

• 执行以下命令安装依赖：

  sudo yum install -y make snappy snappy-devel zlib zlib-devel bzip2 bzip2-devel lz4-devel libasan openssl-devel cmake3 mysql-devel mxml-devel
  

  Ubuntu

• 执行以下命令安装依赖：

  sudo apt-get install make snappy libsnappy-dev zlib1g zlib1g-dev bzip2 liblz4-dev libasan0  openssl libmxml-dev
  

mkdir build

cmake ../

• 默认编译配置不包含测试用例，如需要编译test文件夹下的测试用例，需要再cmake时添加参数 -DCMAKE_TEST_OPTION=ON

  cmake -DCMAKE_TEST_OPTION=ON ../
  

make

make install
