我正在尝试用 cppunit 测试我的 qt 项目。测试项目使用 MFC。我正在使用 Visual Studio 2010。

我已经包含了 qt 库、dll 并在项目设置中进行了其他更改，例如添加预处理器定义来编译我想要测试的 cpp 文件。但是当我编译这个cpp文件时，我得到了很多语法错误，位于qt头文件中。编译输出如下：

请帮我解决这些错误..

You must be using QT 4.8.x or older. All version before QT 5.x are compiled with 

/Zc:wchar_t-

(it means: DO NOT treat WChar_t as built in type) which is not compatible with MFC, BOOST or CUDA libraries. You need to switch to QT 5.x in which the flag changed to 

/Zc:wchar_t

(without "minus" on the end) - it is compiled this way (they considered this as a flaw).

Or compile older version with /Zc:wchar_t, by changing it in source file:

QTSRC\mkspecs\win32-msvc2010\qmake.conf

我只能猜测，但是如果您在类定义之后缺少最后一个分号，或者在任何时候缺少右括号，您有时会遇到此类错误。

class XXX
{
};  // <- this one could be missing

在您的 CSettings.cpp 中，检查您在 QIODevice 或 QDebug 之前直接包含的文件。这通常是错误的类（可能是 CSettings.h）
