如何使用ClangCodeModel插件在QtCreator中设置C ++标准? [英] How to set C++ standard in QtCreator with ClangCodeModel plugin?

问题描述

对不起，如果这是一个愚蠢的问题，但是我已经尝试了几乎所有内容，现在就把头撞在墙上.

Sorry if this is a dumb question, but I have already tried almost everything and am banging my head against a wall right now..

问题是，带有Clang Code Model插件的Windows版QtCreator 4.8.0-beta解析了我的项目 作为C ++ 98，而实际上它是C ++ 17.但是，不允许在设置对话框中明确指定标准版本(选项"-std = c ++ 17"无效).

The problem is, QtCreator 4.8.0-beta for Windows with Clang Code Model plugin parses my project as C++98 whereas in fact it is C++17. However specifying the standard version explicitly in the settings dialog is not allowed ("Option "-std=c++17" is invalid").

那么，我如何告诉ClangCodeModel它应该将代码解析为C ++ 17? 我使用CMake构建项目，并且在顶层CMakeLists.txt文件中包含set (CMAKE_CXX_STANDARD 17).

So, how do I tell ClangCodeModel that it should parse code as C++17? I use CMake for building the project and have set (CMAKE_CXX_STANDARD 17) in the top-level CMakeLists.txt file.

谢谢！
