Category: date_time Group: None Status: Open Resolution: None Priority: 5 Submitted By: Zak Kipling (zak-k) Assigned to: Jeff Garland (az_sw_dude) Summary: operator<< for gregorian::date_duration not found Initial Comment: The operator<< for boost::gregorian::date_duration (aka gregorian::days) is not found by name lookup. This appears to be because: * boost::gregorian::date_duration is a typedef to: boost::date_time::date_duration< boost::gregorian::date_duration_rep > where boost::gregorian::date_duration_rep is a typedef to boost::date_time::duration_traits_adapted (defined in date_time/gregorian/greg_duration.hpp) * operator<< for boost::gregorian::date_duration) is defined in the gregorian namespace (defined in date_time/gregorian/gregorian_io.hpp) However, since only the typedef names are in the gregorian namespace, argument-dependent lookup doesn't find it there unless you add: using gregorian::operator<<; to your code, after which the operator works as expected. This occurs for me using both gcc 3.4.5 and 4.0.3, and both with Boost 1.33.1 and current CVS trunk. A possible solution would be to either move the definition of operator<< to the date_time namespace, or pull it into that namespace with a using declaration. I haven't checked all the other gregorian types, but it's possible that similer problems exist. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=1498778&group_id=7586 _______________________________________________ Boost-bugs mailing list Boost-bugs@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/boost-bugs
