次のコードがあります。
#include <iostream>
#include <string>
#include <iomanip>
#include <locale>
#include <boost/date_time/gregorian/gregorian.hpp>
#include <boost/date_time/gregorian/parsers.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
#include <boost/date_time/posix_time/posix_time_io.hpp>
using namespace boost::posix_time;
using namespace boost::gregorian;
int main(int argc, char *argv[])
{
std::string ds("2011-01-02");
date dt(from_string(ds));
date_facet *f=new date_facet("%Y-%m-%d");
std::locale loc=std::locale(std::locale::classic(),f);
std::cout.imbue(loc);
std::cout<<dt<<std::endl;
return 0;
}
コンパイルすると、次のエラーが発生します。
/tmp/ccBWTFcx.o: In function `unsigned short boost::date_time::month_str_to_ushort<boost::gregorian::greg_month>(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)':

これはライブラリ リンクの問題ですか?
