Is there a quick way to determine the version of the Boost C++ libraries on a system?
Tested with boost 1.51.0:
std::cout << "Using Boost "
<< BOOST_VERSION / 100000 << "." // major version
<< BOOST_VERSION / 100 % 1000 << "." // minor version
<< BOOST_VERSION % 100 // patch level
<< std::endl;
Output: Using Boost 1.51.0
Tested with boost versions 1.51.0 to 1.65.0
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
As to me, you can first(find version.hpp the version variable is in it, if you know where it is(in ubuntu it usually in /usr/include/boost/version.hpp
by default install)):
locate `boost/version.hpp`
Second show it's version by:
grep BOOST_LIB_VERSION /usr/include/boost/version.hpp
or
grep BOOST_VERSION /usr/include/boost/version.hpp.
As to me, I have two version boost installed in my system. Output as below:
xy@xy:~$ locate boost/version.hpp |grep boost
/home/xy/boost_install/boost_1_61_0/boost/version.hpp
/home/xy/boost_install/lib/include/boost/version.hpp
/usr/include/boost/version.hpp
xy@xy:~$ grep BOOST_VERSION /usr/include/boost/version.hpp
#ifndef BOOST_VERSION_HPP
#define 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 105800
// BOOST_LIB_VERSION must be defined to be the same as BOOST_VERSION
# or this way more readable
xy@xy:~$ grep BOOST_LIB_VERSION /usr/include/boost/version.hpp
// BOOST_LIB_VERSION must be defined to be the same as BOOST_VERSION
#define BOOST_LIB_VERSION "1_58"
Show local installed version:
xy@xy:~$ grep BOOST_LIB_VERSION /home/xy/boost_install/lib/include/boost/version.hpp
// BOOST_LIB_VERSION must be defined to be the same as BOOST_VERSION
#define BOOST_LIB_VERSION "1_61"
Might be already answered, but you can try this simple program to determine if and what installation of boost you have :
#include<boost/version.hpp>
#include<iostream>
using namespace std;
int main()
{
cout<<BOOST_VERSION<<endl;
return 0;
}
Boost installed on OS X using homebrew has desired version.hpp
file in /usr/local/Cellar/boost/<version>/include/boost/version.hpp
(note, that the version is already mentioned in path).
I guess the fastest way to determine version on any UNIX-like system will be to search for boost
in /usr
:
find /usr -name "boost"
Another way to get current boost version (Linux Ubuntu):
~$ dpkg -s libboost-dev | grep Version
Version: 1.58.0.1ubuntu1
