Trouble linking boost libaries in Visial Studio 2010.

Question

I compiled my boost libaries according to the guide found here and tried to use the boost filesystem libary.

When I add #include <boost\filesystem\operations.hpp> I get the following errors:

error LNK2028: unresolved token (0A00009A) "class boost::system::error_code __clrcall boost::filesystem2::detail::dir_itr_close(void * &)" (?dir_itr_close@detail@filesystem2@boost@@$$FYM?AVerror_code@system@3@AAPAX@Z) referenced in function "public: __clrcall boost::filesystem2::detail::dir_itr_imp<class boost::filesystem2::basic_path<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,struct boost::filesystem2::path_traits> >::~dir_itr_imp<class boost::filesystem2::basic_path<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,struct boost::filesystem2::path_traits> >(void)" (??1?$dir_itr_imp@V?$basic_path@V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@Upath_traits@filesystem2@boost@@@filesystem2@boost@@@detail@filesystem2@boost@@$$FQAM@XZ)

If I compile without including operations.hpp it works fine. The thing is that when I use #define BOOST_LIB_DIAGNOSTIC It shows that it is linking in the boost libaries correctly:

Linking to lib file: libboost_filesystem-vc100-mt-gd-1_44.lib
Linking to lib file: libboost_system-vc100-mt-gd-1_44.lib

I'd be grateful if anyone could offer advice.

In the project options (at linker option group) add the missing libraries at dependencies, and add the path to boost libraries in the additional directories. Or, to enable automatic linking (if you compiled boost as DLLs) define BOOST_ALL_DYN_LINK in the preprocessor symbols in C++ options, in the project.
