Issues in files qdebug.h, qmetatype.h, qhashfunctions.h, qtextstream.h

Tohakrat

When I add qmap.h I get issues.
Examples:
string: return QtPrivate::QStringList_join(self(), sep.constData(), sep.length());

issue: D:\SOFT\QT\5.12.5\mingw73_32\include\QtCore\qstringlist.h:204: error: invalid use of incomplete type 'const class QString'

But I havent added these files, so where this errors from?
return QtPrivate::QStringList_join(self(), sep.constData(), sep.length());
^~~

Hi and welcome to devnet,

Why are you not using:

#include <QMap>

as shown in the documentation ?

Im using <QMap>, this isnt help.
Cout of errors are very big. Thanks in advance.

I wonder if you made a search and replace that modified your Qt includes.
