Hello, I am using Boost 1.41.0 with Visual Studio 2005 and noticed some strange behaviour which I am unsure how to fix. When I call boost::filesystem::remove_all("somepath"); everything compiles and links fine. But now a project works entirely on wstring basis so it happens that I pass something like boost::filesystem::remove_all(L"somepath"); Code compiles still fine but it throws many linker errors like Fehler 2 error LNK2001: nresolved external symbol ""__declspec(dllimport) class boost::filesystem::file_status __cdecl boost::filesystem::detail::status_api(class std::basic_string<unsigned short,struct std::char_traits<unsigned short>,class std::allocator<unsigned short> > const &,class boost::system::error_code &)" (__imp_?status_api@detail@filesystem@boost@@YA?AVfile_status@23@ABV?$basic_string@GU?$char_traits@G@std@@V?$allocator@G@2@@std@@AAVerror_code@system@3@@Z)". Fehler 3 error LNK2001: nresolved external symbol ""__declspec(dllimport) public: static class std::basic_string<unsigned short,struct std::char_traits<unsigned short>,class std::allocator<unsigned short> > __cdecl boost::filesystem::wpath_traits::to_external(class boost::filesystem::basic_path<class std::basic_string<unsigned short,struct std::char_traits<unsigned short>,class std::allocator<unsigned short> >,struct boost::filesystem::wpath_traits> const &,class std::basic_string<unsigned short,struct std::char_traits<unsigned short>,class std::allocator<unsigned short> > const &)" (__imp_?to_external@wpath_traits@filesystem@boost@@SA?AV?$basic_string@GU?$char_traits@G@std@@V?$allocator@G@2@@std@@ABV?$basic_path@V?$basic_string@GU?$char_traits@G@std@@V?$allocator@G@2@@std@@Uwpath_traits@filesystem@boost@@@23@ABV45@@Z)". So what happens here? I searched boost for some wstring support or similar but had no luck. It is quite unhandy to transform to and from wstring<>string.
