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，但我认为此结构的signals成员与Qt signals关键字冲突.

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'

如何使CDK与Qt配合使用?

How can I get CDK to work with Qt?

推荐答案

您可以定义QT_NO_KEYWORDS宏，该宏将禁用信号"和插槽"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

(此处的Qt文档)

如果您使用的是另一个构建系统，请执行将-DQT_NO_KEYWORDS传递给编译器的所有操作.

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

定义QT_NO_KEYWORDS将要求您在Qt代码中将出现的signals更改为Q_SIGNALS，将slots更改为Q_SLOTS.

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，例如因为使用的第三方库不是干净关键字"，所以可以在包含cdk.h之前尝试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，我建议您使用no_keywords，因为它不太繁琐且容易出错.

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