Hi Rainer, I'm trying to link statically so setting this option would require dynamic linking and another lib: boost_program_options-vc80-mt-gdp-1_34_1.lib When I try to build this lib, I get a lot of warnings of this kind: ..\..\..\boost/program_options/errors.hpp(21) : warning C4275: non dll-interface class 'std::logic_error' used as base for dll-int erface class 'boost::program_options::error' D:\Program Files\Microsoft Visual Studio 8\VC\INCLUDE\stdexcept(22) : see declaration of 'std::logic_error' ..\..\..\boost/program_options/errors.hpp(21) : see declaration of 'boost::program_options::error' ..\..\..\boost/program_options/errors.hpp(61) : warning C4251: 'boost::program_options::ambiguous_option::alternatives' : class 's td::vector<_Ty>' needs to have dll-interface to be used by clients of class 'boost::program_options::ambiguous_option' with [ _Ty=std::string ] I eventually was able to build this lib and when I build my project I still got the same warnings and the same error :( -----Message d'origine----- De : boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] De la part de Rainer Thaden Envoyé : mercredi 5 mars 2008 18:20 À : boost-users@lists.boost.org Objet : Re: [Boost-users] link problem: boost + stlport + msvc8 Hi Gabriel,

I'm trying to write a tiny program, just to get stlport and boost to play nice together and I still have "unresolved external symbol" errors.

When I tried to link, I got an error saying that libboost_program_options-vc80-mt-gdp-1_34_1.lib could not be found, so I had to build it.

Just a guess: Did you add BOOST_ALL_DYN_LINK to your preprocessor definitions?
