Re: [Boost-users] is leaf() be defined at boost/filesystem/operations.hpp ?

I suppose that Lars did help you. See http://www.boost.org/doc/libs/1_47_0/libs/filesystem/v3/doc/deprecated.html for differences between v2 and v3. You can see for yourself that 'leaf' has been removed from v3 which is currently the default using Boost.FileSystem.
