Global QVector struct how to?

[qDebug]

Hey guys!

Need some help on how to get a global QVector and a struct working without LNK2001/LNK2005 errors.

Here is my global.h file:

#ifndef GLOBAL_H
#define GLOBAL_H

#include <QString>
#include <QVector>

struct gUser {
    int id;
    QString name;  
};

extern QVector<gUser> Users;

#endif // GLOBAL_H

In my cpp files i include the global.h from above and get LNK errors. I did try serval other ways but non of them works so far. Is there something wrong with my declaration or? I don't know and hope some onre here can help me out.

Thanks!

@qDebug said in Global QVector struct how to?:

extern QVector<gUser> Users;

One (and only one) .cpp file must define storage for the variable:

QVector<gUser> Users;

The fact that it is a vector of structs is not relevant.

Thank you, that solved my problem :)

Now that you wrote it, i remember how it worked in c++. Only one cpp file QVector<gUser> Users; and others extern QVector<gUser> Users; for access.

Thanks!
