The following two lines don't compile with the EDG 304 based Tru64 cxx compiler: #include <time.h> #include "boost/date_time/gregorian/gregorian.hpp" The full error message is attached. It looks like this struct is instantiated with C = char: namespace boost { template< typename C > struct range_const_iterator { typedef typename C::const_iterator type; }; } I tried adding a full specialization for range_const_iterator<char> but this didn't help. Older EDG's seem to have the same problem. Does someone have experience compiling the date_time library with an EDG-based compiler? I'd be grateful for suggestions. Thanks!
