Hi boost-users, I'm consuming boost 1.69 successfully from vcpkg, on a number of platforms, including MSVC and clang-cl on Windows. However, for some reason, whilst my MSVC is more or less clean of warnings, the clang-cl build is littered with LNK4217's. These appear to be related to boost.log, and more specifically get_tss_data and set_tss_data: warning LNK4217: locally defined symbol ?get_tss_data@detail@boost@@YAPEAXPEBX@Z (void * __cdecl boost::detail::get_tss_data(void const *)) imported in function "public: struct boost::log::v2s_mt_nt6::sinks::basic_formatting_sink_frontend<char>::formatting_context * __cdecl boost::thread_specific_ptr<struct boost::log::v2s_mt_nt6::sinks::basic_formatting_sink_frontend<char>::formatting_context>::get(void)const " (?get@?$thread_specific_ptr@Uformatting_context@?$basic_formatting_sink_frontend@D@sinks@v2s_mt_nt6@log@boost@@@boost@@QEBAPEAUformatting_context@?$basic_formatting_sink_frontend@D@sinks@v2s_mt_nt6@log@2@XZ) warning LNK4217: locally defined symbol ?set_tss_data@detail@boost@@YAXPEBXV?$shared_ptr@Utss_cleanup_function@detail@boost@@@2@PEAX_N@Z (void __cdecl boost::detail::set_tss_data(void const *,class boost::shared_ptr<struct boost::detail::tss_cleanup_function>,void *,bool)) imported in function "public: __cdecl boost::thread_specific_ptr<struct boost::log::v2s_mt_nt6::sinks::basic_formatting_sink_frontend<char>::formatting_context>::~thread_specific_ptr<struct boost::log::v2s_mt_nt6::sinks::basic_formatting_sink_frontend<char>::formatting_context>(void)" (??1?$thread_specific_ptr@Uformatting_context@?$basic_formatting_sink_frontend@D@sinks@v2s_mt_nt6@log@boost@@@boost@@QEAA@XZ) Googling revealed that this problem indicates some issue on exports (e.g. __declsepc...), but I haven't managed to figure out exactly what is causing it. Have you seen anything of this ilk? Any pointers would be greatly appreciated.
