c++ - qlist.h(466)：错误 C2061：语法错误：标识符“n”

问题描述

我在我的一个项目中包含 Qt 库时遇到问题。包括：

#include <QtCore/QString>
#include <QtXml/QDomDocument>
#include <iostream>

#pragma push_macro("realloc")
#undef realloc
#include <QtCore/QFile>
#include <QtCore/QFileInfo>
#include <QtCore/QDir>
#pragma pop_macro("realloc")

包括 QFile ， QFileInfo 并 QDir 导致此错误：

C:\qt\5.15.0\msvc2019_64\include\QtCore\qlist.h(466): error C2061: syntax error: identifier 'n'
C:\qt\5.15.0\msvc2019_64\include\QtCore\qlist.h(464): note: while compiling class template member function 'void QList<QString>::node_construct(QList<QString>::Node *,const T &)'
      with
      [
          T=QString
      ]

使用 push/pop 宏是因为与 realloc 模板类似的错误，此处已解决：Qt: not enough arguments for function-like macro invocation 'realloc', qvector.h。
