[Boost-users] Trying to extract sub library from Boost using BCP

I'm trying to extract "just what I need" from Boost to reduce the checkin footprint. So far I'm doing the following (On Windows): bootstrap.bat b2 tools/bcp md extract dist\bin\bcp boost/thread.hpp boost/shared_ptr.hpp boost/enable_shared_from_this.hpp boost/asio.hpp boost/thread/thread.hpp boost/bind.hpp boost/thread/lock_types.hpp boost/thread/condition_variable.hpp .\extract cd extract ..\b2but this gives me an error: boostcpp.jam: No such file or directory link.jam: No such file or directory Jamroot:137: in modules.load ERROR: rule "boostcpp.set-version" unknown in module "Jamfile". C:/temp/boost_1_55_0/tools/build/v2/build\project.jam:311: in load-jamfile C:/temp/boost_1_55_0/tools/build/v2/build\project.jam:64: in load C:/temp/boost_1_55_0/tools/build/v2/build\project.jam:145: in project.find C:/temp/boost_1_55_0/tools/build/v2\build-system.jam:535: in load C:\temp\boost_1_55_0\tools\build\v2/kernel\modules.jam:289: in import C:\temp\boost_1_55_0\tools\build\v2/kernel/bootstrap.jam:139: in boost-build C:\temp\boost_1_55_0\boost-build.jam:17: in module scopeWhat am I doing wrong? What is the correct way to compile the extracted sub-library? Thanks Colin
