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

blocks|key|1144478|text|使用自制软件安装在OS+X上的Boost需要/usr/local/Cellar/boost/<version>/include/boost/version.hpp中的version.hpp文件(请注意，路径中已经提到了该版本)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1144479|我想在任何类UNIX系统上确定版本的最快方法是在/usr中搜索boost|1144480|find+/usr+-name+"boost"|1144481|entityMap^0|M|1N|2B|B|0|O|4|V|5|0|0|N|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|V|8|@$9|W|A|X|B|C]]|D|@]|E|$]]|$1|J|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|K|$]]

Boost installed on OS X using homebrew has desired <code>version.hpp</code> file in <code>/usr/local/Cellar/boost/&lt;version&gt;/include/boost/version.hpp</code> (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 <code>boost</code> in <code>/usr</code>:

<code>find /usr -name "boost"</code>

blocks|key|1144516|text|根据您安装boost的方式和运行的操作系统，您还可以尝试以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1144517|dpkg+-s+libboost-dev+%7C+grep+'Version'|code-block|syntax|javascript|1144518|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Depending on how you have installed boost and what OS you are running you could also try the following:

<pre><code>dpkg -s libboost-dev | grep 'Version'
</code></pre>

blocks|key|1144578|text|可能已经回答了，但是您可以尝试这个简单的程序来确定您是否安装了boost以及安装了什么：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1144579|#include<boost/version.hpp>

using+namespace+std;
int+main()

Might be already answered, but you can try this simple program to determine if and what installation of boost you have : 

<pre><code>#include&lt;boost/version.hpp&gt;
#include&lt;iostream&gt;
using namespace std;
int main()
{
cout&lt;&lt;BOOST_VERSION&lt;&lt;endl;

@Vertexwahns answer, but written in bash. For the people who are lazy:
<pre><code>boost_version=$(cat /usr/include/boost/version.hpp | grep define | grep &quot;BOOST_VERSION &quot; | cut -d' ' -f3)
echo &quot;installed boost version: $(echo &quot;$boost_version / 100000&quot; | bc).$(echo &quot;$boost_version / 100 % 1000&quot; | bc).$(echo &quot;$boost_version % 100 &quot; | bc)&quot;
</code></pre>
Gives me <code>installed boost version: 1.71.0</code>
