Been looking at this one for a bit, and thought I would post to see if anyone else has has this problem. BASIC INFO: I am running OS X 10.4.2 I have Bjam successfully configured to build boost and run the regression tests (YEAH!) In user-config.jam, I have set my tools=darwin as opposed to gcc (gcc does NOT work on Mac OS with boost due to the "zerolink" functionality apple added to GCC) I have been searching google and so far have found other people with a simliar problem, most notably when porting BSD apps to OSX. (but as of yet no solution) As it sits right now, I am trying to get the documentation to build with BJAM, but running the jamfile in \boost_root\docs is failing on a build of Quickbook. Below is the details of the attempted BJAM of quickbook directly. Any thoughts or help appreciated. Thanks, Brian DETAILS: $ bjam --v2 warning: Python location is not configured warning: the Boost.Python library won't be built Building Boost.Regex with the optional Unicode/ICU support disabled.
