Hi,

I tried to compile boost python so that it links against the debug version. I therefore run

bjam toolset=msvc-9.0 threading=multi python-debugging=on link=shared variant= debug libs\python\build

Running it with -n shows, that it sets -DBOOST_DEBUG_PYTHON, but it still links with python25.lib.

It only picks "right" python25_d.lib, if I add something to my user-config.jam, like the following:

using python : 2.5 : C:\\src\\Python-2.5\\PCBuild\\python ; using python : 2.5 : C:\\src\\Python- 2.5\\PCBuild\\python_d : # includes : # libs : <python-debugging>on ;

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?

They're not separate methods. The user-config.jam entry is necessary because Boost.Build's auto-configuration for Python doesn't look for debug builds of Python. Even if you add that entry, if (as above) it isn't the only instance of "using python," you will need "python-debugging=on" on the command-line. To get both variants built in one bjam invocation, you can use python-debugging=on python-debugging=off or python-debugging=on,off HTH, and sorry this took so long. -- Dave Abrahams Boost Consulting http://boost-consulting.com
