QMessageBox::information crashes the app on macOS (ARM)

128 views Asked by At

I have the 'msgtest' QtCreator project:

msgtest.pro

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++17

# 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 \
    mainwindow.cpp

HEADERS += \
    mainwindow.h

FORMS += \
    mainwindow.ui

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

mainwindow.h

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QMessageBox>

QT_BEGIN_NAMESPACE
namespace Ui { class MainWindow; }
QT_END_NAMESPACE

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    MainWindow(QWidget *parent = nullptr);
    ~MainWindow();

private slots:
    void on_pushButton_clicked();

private:
    Ui::MainWindow *ui;
};
#endif // MAINWINDOW_H

main.cpp

#include "mainwindow.h"

#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    return a.exec();
}

mainwindow.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}

MainWindow::~MainWindow()
{
    delete ui;
}


void MainWindow::on_pushButton_clicked()
{
   QMessageBox::information(nullptr, "Login success.", "You have successfully logged in!");
}

mainwidnow.ui enter image description here

The important part is the pushButton slot void MainWindow::on_pushButton_clicked() in mainwindow.cpp:

void MainWindow::on_pushButton_clicked()
{
   QMessageBox::information(nullptr, "Login success.", "You have successfully logged in!");
}

The problem is that when I click the button the program crashed and MacOS want me to send crash report to Apple. Why QMessageBox::information wont work?

I am trying to find something about my situation on the web for 2 days without success. Hope You will help me out.

My setup: MacBook Air M2 (ARM), MacOS Sonoma 14.0, Qt Creator 11.0.3, Qt kit:

The debugger output: enter image description here

As @alagner mentioned, homebrew's Qt is kinda broken on apple silicon, so to solve this I have removed qt and qt-creator packages with brew and installed qt creator and libraries with https://www.qt.io/download-qt-installer . It's kinda sad that I cant just type brew install qt qt-creator anymore to boot strap qt workflow on new Mac from command line.

BUT now, the QMessageBox::information(nullptr, "Login success.", "You have successfully logged in!"); does not break the app.

Thank you all guys!
