 The following code is compiled under VC2012:

 {{{
 #include <boost/filesystem.hpp>
 boost::filesystem::path p("file.txt");
 size_t hash = boost::filesystem::hash_value(p);
 }}}

 but gives link error:

 {{{
 error LNK2019: unresolved external symbol "void __cdecl
 boost::hash_combine<wchar_t>(unsigned int &,wchar_t const &)"
 (??$hash_combine@_W_at_boost@@YAXAAIAB_W_at_Z) referenced in function "unsigned
 int __cdecl boost::filesystem::hash_value(class boost::filesystem::path
 const &)" (?hash_value_at_filesystem@boost@@YAIABVpath_at_12@@Z)
 }}}

 I fixed it by replacing

 {{{
 #include <boost/functional/hash_fwd.hpp>
 }}}

 with

 {{{
 #include <boost/functional/hash.hpp>
 }}}
