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

Question

I need to have my boost library in a version of 1.40. How do I check my version of the boost library?

I am trying to compile the PCL library, like described in http://pointclouds.org/downloads/source.html.

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
