Config after 6.3.1. installation

[britsfp]

Hello everyone,
After Qt6.3.1. got installed by openSUSE Leap 15.4 upgrade, I get this error when trying to compile and run a project::
====================
/prog/Qt6.3/6.3.1/gcc_64/include/QtCore/qfile.h:49: error: filesystem: No such file or directory
In file included from ../../../../Qt6.3/6.3.1/gcc_64/include/QtCore/qdir.h:44:0,
from ../../../../Qt6.3/6.3.1/gcc_64/include/QtCore/QtCore:75,
from ../Maxbet/mainwindow.h:5,
from ../Maxbet/main.cpp:1:
../../../../Qt6.3/6.3.1/gcc_64/include/QtCore/qfile.h:49:10: fatal error: filesystem: No such file or directory
#include <filesystem>
^~~~~~~~~~~~
======================
Does anyone know what causes this??
That gfile.h file is a header file installed when Qt is installed, and I do not think one should modify it. So the "filesystem" file seem to be missing ??

@britsfp said in Config after 6.3.1. installation:

#include <filesystem>

filesystem is a C++17 feature - did you enable C++17 in your project?

@jsulm Hello,
I looked around in the IDE and do not see a place where I can enable this.
Can you please tell me where to go in the IDE for this.

Hi,

It's not at the IDE level but your project file.

Are you using qmake or cmake ?

@SGaist , Hello,
I am using qmake because I had huge problems with cmake.

@britsfp Add

CONFIG += c++17

to your pro file.
