glog是google出品的一個(gè)C++日志庫
CentOS下glog的使用簡介

安裝依賴的庫

yum install glog-devel.x86_64
yum install gflags-devel.x86_64

編寫代碼client.cpp

#include <iostream>
#include <glog/logging.h>
using namespace std;

static void InitLog(const char* cmd)
{
    FLAGS_logbufsecs = 0;
    google::InitGoogleLogging(cmd);
    FLAGS_log_dir = "/root/log/";
}

int main(int argc, char** argv)
{
    InitLog(argv[0]);
    LOG(INFO)<<"Hello world glog";
    cout<<"hello world"<<endl;
    return 0;
}

編寫Makefile

client:client.cpp
    g++ -g client.cpp -o client -lglog
