How to determine the Boost version on a system?

Is there a quick way to determine the version of the Boost C++ libraries on a system?

Solution 1:

Boost Informational Macros. You need: BOOST_VERSION

Solution 2:

Include #include <boost/version.hpp>

std::cout << "Using Boost "     
          << BOOST_VERSION / 100000     << "."  // major version
          << BOOST_VERSION / 100 % 1000 << "."  // minor version
          << BOOST_VERSION % 100                // patch level
          << std::endl;

Possible output: Using Boost 1.75.0

Tested with Boost 1.51.0 to 1.63, 1.71.0 and 1.76.0 to 1.78.0

Solution 3:

If you only need to know for your own information, just look in /usr/include/boost/version.hpp (Ubuntu 13.10) and read the information directly

Solution 4:

#include <boost/version.hpp>
#include <iostream>
#include <iomanip>

int main()
{
    std::cout << "Boost version: " 
          << BOOST_VERSION / 100000
          << "."
          << BOOST_VERSION / 100 % 1000
          << "."
          << BOOST_VERSION % 100 
          << std::endl;
    return 0;
}

Update: the answer has been fixed.
