-- Sorry if this message is duplicated --

I'm preety new to Boost :-)

When I try to compile / link this little program:

#include <boost/date_time/gregorian/gregorian.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
using namespace boost::gregorian;

#include <string>
using namespace std;

int main() {

try {
  string myString = "2005/10/13";
  date myDate( from_string( myString ) );
  cout << myDate << endl;
} catch ( ... ) {
  cout << "Exception" << endl;
}
}

I receive the following message from Borland 5.5.1:

Turbo Incremental Link 5.00 Copyright (c) 1997, 2000 Borland

And this one from g++ 3.4.4:

nce to `boost::gregorian::greg_month::get_month_map_ptr()'
collect2: ld returned 1 exit status

I can't figure out what's happening, but I'm sure the problem is from_string(). When I don't use it, everything works fine.

Can someone help me?

Boost version: 1_33_0
