Hi, I have compiled Boost.Buildv2 from the Boost V1.47 sources and have successfully compiled the Boost libraries with it. Now I want to use BBv2 in my own project, which uses the Boost libraries. So I tried using the Boost library support module: I added to my user-config.jam: using boost : 1.47 : <include>C:/boost_1_47_0/boost <library>C:/boost_1_47_0/stage/lib ; and to my project's jamroot file: import boost ; boost.use-project 1.47 ; I installed BBv2 to C:/boost_1_47_0/bjam and added this to the PATH. Calling bjam gives me the following error message, because it can't find the support module (I assume): boost.jam: No such file or directory C:/boost_1_47_0/bjam/share/boost-build/build\toolset.jam:38: in toolset.using rule boost.init unknown in module toolset. C:/boost_1_47_0/bjam/share/boost-build/build\project.jam:888: in using C:\Users\zaphod\user-config.jam:3: in modules.load C:/boost_1_47_0/tools/build/v2\build-system.jam:257: in load-config C:/boost_1_47_0/tools/build/v2\build-system.jam:399: in load-configuration-files C:/boost_1_47_0/tools/build/v2\build-system.jam:555: in load C:\boost_1_47_0\bjam\share\boost-build\kernel\modules.jam:283: in import C:\boost_1_47_0\bjam\share\boost-build\kernel\bootstrap.jam:142: in boost-build C:\boost_1_47_0\bjam\share\boost-build\boost-build.jam:8: in module scope I located boost.jam in the source tree of bbv2 of the boost libraries in the directory contrib. This is on Windows 7 x64 with mingw(32) as compiler. What is wrong here? Can I help bjam finding the boost.jam file? Many thanks in advance, Marcel
