I have a very simple app that I’m trying to link with the Boost date_time library.  It links and runs fine with I build against the RELEASE configuration.  But I get the following link errors when when I use the DEBUG configuration:

2>TimeUtil.obj : error LNK2019: unresolved external symbol "public: char const * __cdecl boost::gregorian::greg_month::as_long_string(void)const " (?as_long_string@greg_month@gregorian@boost@@QBAPBDXZ) referenced in function "public: static class stlpd_std::basic_ostream<wchar_t,class stlpd_std::char_traits<wchar_t> > & __cdecl boost::date_time::month_formatter<class boost::gregorian::greg_month,class boost::date_time::iso_extended_format<wchar_t>,wchar_t>::format_month(class boost::gregorian::greg_month const &,class stlpd_std::basic_ostream<wchar_t,class stlpd_std::char_traits<wchar_t> > &)" (?format_month@?$month_formatter@Vgreg_month@gregorian@boost@@V?$iso_extended_format@_W@date_time@3@_W@date_time@boost@@SAAAV?$basic_ostream@_WV?$char_traits@_W@stlpd_std@@@stlpd_std@@ABVgreg_month@gregorian@3@AAV45@@Z)

2>TimeUtil.obj : error LNK2019: unresolved external symbol "public: char const * __cdecl boost::gregorian::greg_month::as_short_string(void)const " (?as_short_string@greg_month@gregorian@boost@@QBAPBDXZ) referenced in function "public: static class stlpd_std::basic_ostream<wchar_t,class stlpd_std::char_traits<wchar_t> > & __cdecl boost::date_time::month_formatter<class boost::gregorian::greg_month,class boost::date_time::iso_extended_format<wchar_t>,wchar_t>::format_month(class boost::gregorian::greg_month const &,class stlpd_std::basic_ostream<wchar_t,class stlpd_std::char_traits<wchar_t> > &)" (?format_month@?$month_formatter@Vgreg_month@gregorian@boost@@V?$iso_extended_format@_W@date_time@3@_W@date_time@boost@@SAAAV?$basic_ostream@_WV?$char_traits@_W@stlpd_std@@@stlpd_std@@ABVgreg_month@gregorian@3@AAV45@@Z)

It is linking against “libboost_date_time-vc90-mt-sgdp-1_38.lib”.  Using undname, I can see that the library is using the __thiscall convention instead of __cdecl.  Is this a problem in my configuration for building the Boost date_time library, or a problem in my app’s build configuration?

Thanks in advance for any help!
