Doubts about QtConcurrent::run and members functions

[vcp]

Hi All, Happy new year!

I've tried to use QtConcurrent::run with members functions, but I have not had success.
Then I resolved to quiz this example of documentation:

QString string = "red,blue,green";
QFuture<QStringList> future = QtConcurrent::run(string, &QString::split, QString(", "), QString::KeepEmptyParts, Qt::CaseSensitive);
 QStringList result = future.result();

QString string = "red,blue,green";
QFuture<QStringList> future = QtConcurrent::run(string, &QString::split, QString(", "), QString::KeepEmptyParts, Qt::CaseSensitive);
 QStringList result = future.result();

To copy to clipboard, switch view to plain text mode 

But the following error of compilation occurs

qreport.cpp: In constructor 'qreport::qreport()':
qreport.cpp:57: error: no matching function for call to 'run(QString&, <unresolved overloaded function type>, QString, QString::SplitBehavior, Qt::CaseSenitive);

What is happening?

Thanks in advance.
