[Boost-users] base class should be explicitly initialized in the copy constructor

Hello, I have a question regarding the warning that I get when I compile a program using boost::ublas library. I have to say that I'm not really experienced programmer so I might be doing something really stupid... Anyway, I'm using WinXP with Mingw 3.4.5 and boost 1.34-1. I want to create a simple function that returns a vector. I have it written like this: ################################################################

====== file.h ====== < #include typedef boost::numeric::ublas::vector<double> vec;

vec testfunc (vec &v);

====== file.cpp ====== < #include "file.h"

vec testfunc (vec &v) { vec v1 = v/2; return v1; } #################################################################### When I try to compile, I get the following warning: base class `class boost::numeric::ublas::storage_array >' should be explicitly initialized in the copy constructor How can I get rid of this warning? Thank you very much for your answers.
