The glog library implements application-level logging. This library provides logging APIs based on C++-style streams and various helper macros.

The main function:

1. Parameter setting, setting flag parameters in the form of command line parameters to control logging behavior;
2. Severity classification, recording logs according to log severity classification;
3. Logging information can be recorded conditionally;
4. Conditional termination of the program. Abundant conditional judgment macros can preset program termination conditions;
5. Exception signal processing. Program exceptions, you can customize the exception handling process;
6, support the debug function. Can only be used in debug mode;
7, custom log information;
8, thread-safe logging method;
9, system-level logging;
10, google perror style log information;

11. Simplify the log string information.

glog installation and use under window

After downloading, unzip it, and use Visual Studio to open google-glog.sln. Generate a solution

Open sln and there will be several projects, libglog is a dynamic library, which generates dll, and libglog_static is a static library, which generates lib.

Install:

Method 1: Copy the libglog.dll and libglog.lib files to your project folder, and copy the glog directory under src\windows\ to your project file.

Method 2: You can also copy these two files to the system folder for global access.

1. Copy libglog.dll to C:\Program Files\Microsoft Visual Studio 14.0\VC\bin

2. Copy libglog.lib to C:\Program Files\Microsoft Visual Studio 14.0\VC\lib

3. Copy the glog directory to C:\Program Files\Microsoft Visual Studio 14.0\VC\include

test program

#include "glog/logging.h"    
#include <iostream>    
#include <vector>    
using namespace std;    
#pragma comment(lib,"libglog.lib")    
  
int main(int argc, char* argv[])  
{  
    // Initialize Google's logging library.    
    google::InitGoogleLogging(argv[0]);    
    google::SetLogDestination(google::INFO,"E://glog");    
    // Set log path INFO WARNING ERROR FATAL    
    // ...    
    char str[20] = "hello log!";    
    LOG(INFO) << "Found " << google::COUNTER <<endl;    
    LOG(INFO) << str ;//<< " cookies";    
    LOG(WARNING) << "warning test"; // will output a Warning log    
    LOG(ERROR) << "error test";//An Error log will be output    
  
    system("pause");  
    return 0;  
}

illustrate:

After compiling and running, you can see the log file in the E:/glog directory.

Compilation possible problems:

glog compiled under vs2010 and
opened google-glog.sln
compiled
successfully

In the Debug folder, there are the files we want, such as libglog.dll libglog.lib, etc.

glog compile under vs2015
open google-glog.sln
compile
error 1: 'min' is not a member of std
Solution:
add header file#include<algorithm>

Error 2: warning C4005: "va_copy": macro redefinition
Solution:
Modify the file port.h, line 117 to:

#undef va_copy
#define va_copy(dst, src)  (dst) = (src)

Error 3:
error C2084: function 'int snprintf(char *const ,const size_t,const char *const ,…)' already has a body
c:\program files (x86)\windows kits\10\include\10.0.10150.0\ucrt \stdio.h(1932): note: see previous definition of "snprintf"

solution:

Modify the name of snprintf, such as snprintf_glog, if you want to change it all, you can use the big tomato plug-in, which is convenient and fast
