Boost Users, I am trying to build the Hello World python example. When I execute bjam I get the "rule python-extension unknown" error. I believe this to be because my user-config.jam file is never being used. The tutorial states to configure the rules in the user-config.jam file in my home directory. My home directory is "C:\Documents and Settings\robert.machardy". I did not find the file there, and this does not appear to be the place for jam files. I found the file user-config.jam in "C:\Program Files\boost\boost_1_36_0\tools\build\v2", I edited it and copied to my home directory. I configured it for the following: # Configure specific msvc version (searched for in standard locations and PATH). using msvc : 7.1 ; using python : 2.6 : C:\Program Files\Python26; Please help. Thank you, Robert MacHardy
