Qt 宏关键字导致名称冲突 [英] Qt macro keywords cause name collisions

问题描述

我正在为我的 Qt 项目构建一个 NCurses 界面.我想使用 CDK，但我认为该结构的 signals 成员与 Qt signals 关键字发生冲突.

I am building an NCurses interface for my Qt project. I want to use CDK but I think the signals member of this struct is colliding with the Qt signals keyword.

/usr/include/linux/cdk.h:411: error: expected unqualified-id before 'protected'

如何让 CDK 与 Qt 一起工作?

How can I get CDK to work with Qt?

推荐答案

您可以定义 QT_NO_KEYWORDS 宏，禁用信号"和槽"宏.

You can define the QT_NO_KEYWORDS macro, that disables the "signals" and "slots" macros.

如果您使用 QMake:

If you use QMake:

 CONFIG += no_keywords

(Qt 文档在这里)

如果您使用其他构建系统，请执行任何需要将 -DQT_NO_KEYWORDS 传递给编译器的操作.

If you’re using another build system, do whatever it needs to pass -DQT_NO_KEYWORDS to the compiler.

定义 QT_NO_KEYWORDS 将要求您将 Qt 中 signals 的出现次数更改为 Q_SIGNALS 并将 slots 的出现次数更改为 Q_SLOTS代码.

Defining QT_NO_KEYWORDS will require you to change occurrences of signals to Q_SIGNALS and slots to Q_SLOTS in your Qt code.

如果您无法更改所有 Qt 代码，例如因为您使用的第三方库不是关键字清理"，您可以尝试在包含 cdk.h 之前在本地取消定义信号":

If you cannot change all the Qt code, e.g. because you're using third-party libraries not being "keyword-clean", you could try to undefine "signals" locally before including cdk.h:

#undef signals
#include <cdk.h>

如果可能的话，我建议使用 no_keywords，因为它不那么乏味且不易出错.

I'd recommend to use no_keywords though if possible, as it is less tedious and error-prone.
