我看了半天也没发现你哪里嵌入了。你有没有#include引入boost的cpp文件？或者：你有没有把boost的cpp文件加入到工程中？sorry
1: std::string now_str(to_simple_string(now)); 1. 2: std::string now_iso_str(to_iso_string(now)); 1. 3: std::string now_iso_ext_str(to_iso_extended_string(now)); 1. 4: std::cout << now_str << std::endl; 1.

>>我们经常还需要将时间转换为string类型,请参考: 1: using namespace boost::gregorian; 2: date today = day_clock::local_day(); 3: std::string str1(to_simple_string(today));//YYYY-MMM-DD, 2013-Jan-11 4: std::string str2(to_iso_string(today));//YYYYMMDD, 20130111 ...
