如何在qt创建者中使用qt的clang 5？

Question

I've configured my locally installed version of clang 5.

and set up a kit with it

but when I do a build with it:

it's clearly still using the system compiler for qmake, which causes a bunch of errors because my code requires C++17 support:

How do I set what compiler qmake is using?

Thank you.

You can do it in your pro file, directly:

QMAKE_CC = /path/to/the/c/compiler
QMAKE_CXX = /path/to/the/c++/compiler

but you'd be better specify the correct Qt mkspec in your kit, which could be something like linux-clang . Check the mkspecs directory, see if in some of its subdirectories there is the right qmake.conf already, if not you can make a new subdirectory in mkspecs and a new configuration file inside it. The mkspecs directory should be in the path given by the terminal command

qmake -query QT_INSTALL_ARCHDATA

Hope it helped.
