Qt Application will not compile

Question

This has been stumping me for a while. I am trying to create a function that takes a hash table, and returns said hash table. However I am getting this error in the header file,

error: ‘string’ was not declared in this scope.
error: template argument 1 is invalid

Here is the header file itself:

#ifndef NAME_SPAWN_H
#define NAME_SPAWN_H
#include <QString>
#include <QHash>
#include <string>

class Name_Spawn
{
public:
    Name_Spawn();
    void initalize();
private:
    QString int_2_str(int);
    void seed();
    QHash<string,QString> setTable(QHash<string,QString>);
};

#endif // NAME_SPAWN_H

As you can see, string has been declared. Any ideas? I am at my wits end.

Answer 1

The real name of string is std::string. Try using that instead.

(You can leave off the std:: qualifier only if there's a using namespace std; directive in scope. But it's a good habit not to put using namespace std; in header files.)
