Hi, I ve a problem with ptime. I'm doing a a project on Eclipse, and I need to create a ptime object from a string. Here's my code: std::string ts("2002-01-20 23:59:59.000"); ptime t(time_from_string(ts)) This code is exactly the same in the boost documentation. On compilation, no error is detected. But there's a problem with the linker. I paste here the error that Eclipse gives to me: Invoking: GCC C++ Linker g++ -o"brol" ./initmain.o ./initmain.o: dans la fonction « unsigned short boost::date_time::month_str_to_ushort<boost::gregorian::greg_month>(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)»: /usr/include/boost/date_time/date_parsing.hpp:67: référence indéfinie vers « boost::gregorian::greg_month::get_month_map_ptr() » collect2: ld returned 1 exit status Do you have an idea?
