Hello, if i want to built the hello.cpp example from the tutorial i get the warning, that it is impossible to find a Jamfile or a project-jam.root. Because all the problems seems to be a lil bit strange, i will describe my configuration as good as possible: the boost-built directory is: /usr/share/boost-build and in the tools/ directory there is no build sub-directory the bjam is in : /usr/bin i have python2.5 bjam --version gives me: Boost.Build V2 (Milestone 11) Boost.Jam 03.1.13 the directory where i copied the hello.cpp, Jamrules, the Jamfile and the boost-build.jam is ~/Boost the hello.cpp is like before. the Jamfile is that: project hello : requirements <library>/boost/python//boost_python : build_dir ~/Boost/ ; python-extension hello: hello.cpp ; the jamrules: path-global BOOST_ROOT : /usr/include/ ; project boost : $(BOOST_ROOT) ; the boost-build.jam: boost-build /usr/share/boost-build/tools ; the user-config.jam are copied in the ~/ and there you can find: import toolset : using ; using gcc ; using python : 2.5 ; Properbly i am overlooking something, but i found no solution until now.
