Hi,<br><br>I tried to compile boost python so that it links against the debug version. I therefore run<br><br>bjam toolset=msvc-9.0&nbsp; threading=multi python-debugging=on link=shared variant=debug libs\python\build<br><br>Running it with -n shows, that it sets -DBOOST_DEBUG_PYTHON, but it still links with 
python25.lib.<br><br>It only picks &quot;right&quot; python25_d.lib, if I add something to my user-config.jam, like the following:<br><br>using python : 2.5 : C:\\src\\Python-2.5\\PCBuild\\python ; using python : 2.5 : C:\\src\\Python-
2.5\\PCBuild\\python_d<br>&nbsp; : # includes<br>&nbsp; : # libs<br>&nbsp; : &lt;python-debugging&gt;on ;<br><br>What is the difference between the two methods (as a bjam argument and in the user-config.jam), and is there a way to combine both on the command line?
<br><br>Thanks and regards,<br><br>Chris<br><br>
