You know what, it is true, I forgot the main(), but, bud, you nailed it!
Ruben, it seems to me that you have a crystal ball or perhaps, somehow, you are
able to access my computer and thus find out exactly what I mean, since I
cannot, sometimes, express myself in the best way possible. If you don’t have a
crystal ball or the ability to access my computer, then, boy, you have a real
talent! I am extremely impress with your performance. Keep up the good work.
Thanks so very much for your help.

Subject: Re: [Mingw-w64-public] unique_ptr and operator<<
2015-07-05 15:40 GMT+02:00 <[email protected]>:
Can anyone, pleeese, tell me why this extractor operator is not causing this
error:
C:\tmp\adfs\main.cpp|20|error: no match for 'operator<<' (operand types are
'std::wostream {aka std::basic_ostream<wchar_t>}' and
'std::unique_ptr<jme::Name>')|
namespace abc{
class MyClass{
private:
int nuestro;
public:
MyClass(){}
virtual MyClass(){}
friend std::wostream& operator<<( std::wostream& os, const abc::Name&
obj );
};//class
}//namespace abc
cpp file
~~~~~~~~
namespace abc{
std::wostream& operator<<(abc::wostream& os, const abc::Name& obj) {
return os << obj.getFirstName() << " "
<< obj.getMiddleName() << " "
<< obj.getLastName();
}//operator<<
} // namespace
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 (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
