With Boost 1.37 (soon to be released), a new macro is introduced called BOOST_THROW_EXCEPTION. You use it like this:
#include "boost/throw_exception.hpp"
struct my_exception: std::exception { };
BOOST_THROW_EXCEPTION(my_exception());
It automatically records the throw location in the exception object. At the catch site, you can use boost::diagnostic_information to get a string that includes the throw location:
#include "boost/exception/diagnostic_information.hpp"
catch( my_exception & e ) { std::cerr << boost::diagnostic_information(e); }
When I try this (on trunk) I get: 1>.\main.cpp(93) : error C2664: 'boost::diagnostic_information' : cannot convert parameter 1 from 'my_exception' to 'const boost::exception &' 1> Reason: cannot convert from 'my_exception' to 'const boost::exception' 1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called ??? -- Eric Niebler BoostPro Computing http://www.boostpro.com
