Hello, I am trying to compile a simple example using the parsers and formatters of the date_time library using g++ under Cygwin. I can successfully build other boost examples passing only the include directory to g++, but all date_time ones that I have tried fail. #include #include #include #include <iostream> using namespace boost::gregorian; int main() { std::string s("2001-10-9"); //2001-October-09 date d(from_simple_string(s)); std::cout << to_simple_string(d) << std::endl; } $g++ -I/usr/include/boost-1_33_1 -o example example.cpp /cygdrive/c/DOCUME~1/USER/LOCALS~1/Temp/cc2nXx0a.o:example.cpp:(.text$_Z N5boos t9date_time19month_str_to_ushortINS_9gregorian10greg_monthEEEtSs[unsigne d short boost::date_time::month_str_to_ushortboost::gregorian::greg_month(std: :basic_s tring)]+0x102): undefined r eference to `boost::gregorian::greg_month::get_month_map_ptr()' /cygdrive/c/DOCUME~1/USER/LOCALS~1/Temp/cc2nXx0a.o:example.cpp:(.text$_Z N5boos t9date_time15month_formatterINS_9gregorian10greg_monthENS0_13simple_form atIcEEcE 12format_monthERKS3_RSo[boost::date_time::month_formatter::format_month(boost::gregor ian::greg_month const&, std::basic_ostream
