Iro*_*ney 5 qmake makefile clang qt-creator c++17
我正在使用QtCreator,Qt 5.10,并尝试在一个完美运行的项目中使用c ++ 17,直到我干净安装最新的Ubuntu并重新安装所有内容.
现在,当调用clang来构建项目时(由于某种原因,我的Clang Relase,Clang Debug和GCC Debug构建......)我从.pro文件中添加了这个额外的编译器标志:
-std=gnu++11
使用我的GCC Release kit(实际调用gcc编译器而不是clang)进行构建时,不会发生这种情况.这个额外的标志覆盖了早期的标志:
-std=c++17
...因为.pro文件中的行而添加:
QMAKE_CXXFLAGS += -std=c++17
我查看了每个构建的makefile,这里是Clang Release构建的Makefile:

现在,我已经查看了我能想到的所有选项,包括每个构建工具包的设置,我不能在我的生活中找出这个错误来自哪里.
知道为什么QMake会添加这个额外的标志,为什么特别为我的Clang构建？知道在QtCreator中我会改变这个吗？我已经尝试更改makefile,但显然QMake在我再次尝试构建时添加了imposter标志.
编辑:
我已经通过下面的valiano建议通过Qt配置文件尝试了一个grep,但到目前为止我没有做任何事情.包含"-std = gnu ++ 11"的文件如下:
/"path-to-qt"/mkspecs/common/qcc-base-qnx.conf
/"path-to-qt"/mkspecs/common/clang.conf
/"path-to-qt"/mkspecs/common/android-base-tail.conf

路径1,2和4是唯一与我的情况相关的东西,并且没有一个包含任何看起来不寻常的东西.

我对 QtCreator 不太熟悉，但使用以下命令设置 C++17 可能会有更好的运气CONFIG：
CONFIG += c++1z
如果CONFIG设置为c++11，则可以解释-std=gnu++11添加该标志的原因。
使用CONFIG应该让 QMake 选择正确的 mkspec 并设置QMAKE_CXXFLAGS所需的-std标志。
