You forgot to show main.
In any case, it should look something like this:
#include <memory>
#include <iostream>
#include "myclass.h"
int main()
{
auto myclass = std::make_unique<MyClass>();
std::wcout << *myclass; // my crystal ball guess is you're missing the
asterisk
}
Try to provide a small self contained compilable example <http://sscce.org/>
(or at least all the code that produces the error).
And again, stop sending these types of queries to a compiler help mailing
list (gcc-help, and kind of mingw-w64-public... I'm also on Stackoverflow,
as are a lot more people to answer you questions). The place for questions
like this is really more something like stackoverflow.com...
Cheers,
Ruben
