如何使用Clang 3.5在QtCreator 3.3中启用C ++ 14支持？我添加了一个Clang工具包，我在我的项目文件中添加了 CONFIG + = c ++ 14 。然而，当使用例如。 我收到以下错误：
How can I enable C++14 support in QtCreator 3.3 using Clang 3.5? I have added a Clang kit and I have added CONFIG += c++14 in my project file. However when using e.g. return type deduction I get the following error:
推荐答案
在构建文件夹中，并用 -std = c ++ 14 手动替换 -std = c ++ 11 。
I had to go to the Makefile in the build folder and manually replace -std=c++11 with -std=c++14.
幸运的是，当您将工具包添加到项目中时，Makefile只写一次。我只需要做这一次，并可以建立在QtCreator的频率，我想要的。
Thankfully the Makefile is only written once when you add the kit to the project. I only had to do this once and could build in QtCreator as often as I want.
现在我可以使用Clang工具包来使用所有新的c ++ 14功能。作为一个奖励，如果我在Makefile中手动设置 -std = c ++ 1z ，我也可以使用所有的c ++ 17功能。 Sweet！
So now I can use a Clang kit to use all the new c++14 features. As a bonus, I can also use all the c++17 features if I manually set -std=c++1z in the Makefile. Sweet!
