問(wèn)題描述

我正在為我的 Qt 項(xiàng)目構(gòu)建一個(gè) NCurses 界面.我想使用 CDK，但我認(rèn)為該結(jié)構(gòu)的 signals 成員與 Qt signals 關(guān)鍵字發(fā)生沖突.

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'

如何讓 CDK 與 Qt 一起工作?

How can I get CDK to work with Qt?

推薦答案

您可以定義 QT_NO_KEYWORDS 宏，禁用信號(hào)"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 文檔在這里)

如果您使用其他構(gòu)建系統(tǒng)，請(qǐng)執(zhí)行任何需要將 -DQT_NO_KEYWORDS 傳遞給編譯器的操作.

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

定義 QT_NO_KEYWORDS 將要求您將 Qt 中 signals 的出現(xiàn)次數(shù)更改為 Q_SIGNALS 并將 slots 的出現(xiàn)次數(shù)更改為 Q_SLOTS代碼.

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

如果您無(wú)法更改所有 Qt 代碼，例如因?yàn)槟褂玫牡谌綆?kù)不是關(guān)鍵字清理"，您可以嘗試在包含 cdk.h 之前在本地取消定義信號(hào)":

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>

如果可能的話，我建議使用 no_keywords，因?yàn)樗荒敲捶ξ肚也灰壮鲥e(cuò).

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