how do you check your version of boost? [duplicate]

Answer 1

Well, take a look at your boost/version.hpp. There is BOOST_VERSION macro for that:

// Example: for boost 1.55.0, taken from boost/version.hpp
//  BOOST_VERSION % 100 is the patch level
//  BOOST_VERSION / 100 % 1000 is the minor version
//  BOOST_VERSION / 100000 is the major version
#define BOOST_VERSION 105500

Answer 2

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

using namespace std;

int main()
{
    cout << "Boost version: " << BOOST_LIB_VERSION << endl;
    return 0;
}

Save the above code as a cpp file. example boost.cpp. Then compile it.

   $ g++ boost.cpp
   $ ./a.out
   Boost version: 1_55

Then you will get your boost library version displayed on your terminal. The example output is printed for Boost 1.55.0.
