Problems converting std::string to LogString: msg#00031apache.logging.log4cxx.user
Hi, I am using the 0.10 version (dll) for log4cxx and when I am trying to call following function: outputLogString = log4cxx::helpers::Transcoder::decode(output); I am getting below linker error! Error 7 error LNK2019: unresolved external symbol "__declspec(dllimport) public: static class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > __cdecl log4cxx::helpers::Transcoder::decode(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)" (__imp_?decode@Transcoder@helpers@log4cxx@@SA?AV?$basic_string@_WU?$char _traits@_W@std@@V?$allocator@_W@2@@std@@ABV?$basic_string@DU?$char_trait s@D@std@@V?$allocator@D@2@@5@@Z) referenced in function "public: virtual void __thiscall com::ml::mllog4cxx::jms::SOALoggerLayout::format(class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > &,class log4cxx::helpers::ObjectPtrT<class log4cxx::spi::LoggingEvent> const &,class log4cxx::helpers::Pool &)const " (?format@SOALoggerLayout@jms@mllog4cxx@ml@com@@UBEXAAV?$basic_string@_WU ?$char_traits@_W@std@@V?$allocator@_W@2@@std@@ABV?$ObjectPtrT@VLoggingEv ent@spi@log4cxx@@@helpers@log4cxx@@AAVPool@9log4cxx@@@Z) soaloggerlayout.obj Can some one please help resolve this? I am using this method as advised in thread http://marc.info/?l=log4cxx-user&m=117816538114449&w=2 Also is there a way or a short tutorial / book that can explain how to interpret these linker errors as I do get these very often. Also I am attaching the build.htm from Visual Studio 2005 (Pro) Please let me know if you need any additional info. -------------------------------------------------------- This message w/attachments (message) may be privileged, confidential or proprietary, and if you are not an intended recipient, please notify the sender, do not use or share it and delete it.
