Google Logging Library

Google Logging (glog) is a C++14 library that implements application-level logging. The library provides logging APIs based on C++-style streams and various helper macros.

How to Use

You can log a message by simply streaming things to LOG(<a particular severity level>), e.g.,

main.cpp

#include <glog/logging.h>

int main(int argc, char* argv[]) {
    google::InitGoogleLogging(argv[0]); 
    LOG(INFO) << "Found " << num_cookies << " cookies"; 
}

The library can be installed using various package managers or compiled from source. For a detailed overview of glog features and their usage, please refer to the user guide.

Warning

The above example requires further Bazel or CMake setup for use in own projects.
