- Jim Jennings (3/29) Mar 30 2003 Or is it Stepanov's code, and who's who?

In article <b62vcc$1oqn$1 digitaldaemon.com>, Jim Jennings says...From Moo & Koenig, "Accelerated C++:good choice of writers!throw domain_error("median of an empty vector");median.cpp(18) : Error: cannot find constructor for class matching std::domain_error::std::domain_error(char *)Add this to your code: #include <string> Why? Probably a problem with typedefed, namespace qualified, forward template references involved in conversions during a throw operation ;-) Richard

In any case, it might be better to get into the habit of including <string> with <stdexcept> rather than adjusting the <stdexcept> lib. This will make sure nothing breaks if/when you upgrade stlport.
