Automatic library linking in boost is done by #including the &lt;boost/config/auto_link.hpp&gt; file.<br><br>In the date_time library this is done via the &lt;boost/date_time/compiler_config.hpp&gt; file.<br><br>Have a search through the date_time tree for references to this compiler_config.hpp file (there&#39;s a whole bunch of them), and you can work where it is being included.<br>
<br>As for the WHY - it looks like the .lib file is needed for some posix_time and gregorian functionality. I&#39;m not too familiar with the lib so that&#39;s all I can tell for now :)<br><br>Regards,<br>Alex<br><br><br>

I used a minimum set of functions in date_time in my VC9 code, but it appears to pull in the date/time DLL by asking for libboost_date_time-vc90-mt-gd-1_35.lib. I can not see where this is being generated but from looking at boost_date_time-vc90-mt-gd-1_35.dll I doubt I am using the functionality in it.<br>

<br>
Does anybody know why it is required ?<br>
