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_ushortboost::gregorian::greg_month(std::basic_string)»: /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?

Yep, you'll need to build and link libboost_datetime to get for this function. Assuming you're using 1.33 you can get the same functionality using the time_facet and a string stream and then you won't need to link the library. See the docs for details on how to use the time_facet if you choose to go that way. Jeff
