Qt 5.10.1, QCoreApplication::applicationFilePath: Please instantiate the QApplication object first

[Athius]

Hello everyone,

I'm working on macOS 10.13.6 with clang (Apple LLVM version 10.0.0 (clang-1000.11.45.2)).

I try to get the application running path. To do this, I use QCoreApplication::applicationFilePath() static method like this:

#include <QApplication>
#include <QDebug>

int main(int argc, char * argv[])
{
      QApplication app(argc, argv);
     
      qDebug() << app.applicationFilePath();
      return app.exec();
}

The code compile correctly but when I launch this app, I have the message:

QCoreApplication::applicationFilePath: Please instantiate the QApplication object first

Does anyone have the same behavior? How to fix it?

Thank you
Romain

Edit: I tried this code using Qt 5.11.1 and it's working but unfortunately my application must be built with compatibility macOS 10.10 and Qt 5.11.* minimum compatibility is macOS 10.11

Edit2: I found the solution: I had some link to another Qt version....
