QT 6.0.1 Windows 10x64 - an empty default console app can't be started

aloz

Hello,

Trying to learn C++ and QT (QT 6.0.1 under Windows 10x64) and my QT Creator can't start even an empty default QT console app.

So, I have just main.cpp:

#include <QCoreApplication>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    return a.exec();
}

and the .pro file:

QT -= gui

CONFIG += c++11 console
CONFIG -= app_bundle

# You can make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
        main.cpp

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

The kit is "Desktop QT 6.0.1 MinGW 64-bit"

The compile output is:

23:50:12: Running steps for project myconsole...

An application output is:

23:49:31: C:\Users\aloz\source\QTProjects\build-myconsole-Desktop_Qt_6_0_1_MinGW_64_bit-Debug\debug\myconsole.exe crashed.

Something with mingw?

after the build I got .exe file that if to start by manually got some errors that some DLLs are missed (Qt6Core, libgcc_s_seh-1,libstdc++-6)

If to copy them from \Qt\6.0.1\mingw81_64\bin\ I got the error message 0xc000007b (possible means that x32 and x64 are mixed)

How to fix it at least to start an empty console app by QT Creator?

Thank you!

Found solution: it was very easy, but need to add to PATH environment variable: c:\Qt\6.0.1\mingw81_64\bin
And now it builds and runs successfully.
p.s. And if to check the box: Projects / Run / Run in terminal - an app. will start is a separate console, as c# console app under Visual Studio :)
