Error when Loading QImage

Christian Ehrlicher

What compiler do you use? How did you install Qt and please show your CMakeLists.txt.

@Christian-Ehrlicher I'm using LLVM MinGW 64 with Qt 6.7.1 in my Qt Creator kit. I installed Qt through the open source installer on the website (https://www.qt.io/download-qt-installer-oss?hsCtaTracking=99d9dd4f-5681-48d2-b096-470725510d34|074ddad0-fdef-4e53-8aa8-5e8a876d6ab4). I installed Qt 6.7.1 through the Qt Creator maintenance tool. I also made the project using QMake, so I don't think I have a CMakeLists.txt file. Here's the .pro file though:

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++17
CONFIG += console

# 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

    mainwindow.h

If you try ,jpg or .gif files, do you still get the same warning, i.e " iCCP: known incorrect sRGB profile"?

bapcruz

@hskoglund I only get that part of the error for pngs.

hskoglund

Just guessing, but if you disable your antivirus app, do you still get the same crash?

bapcruz

@hskoglund I turned off Windows real time virus protection and disabled all UAC. I also ran QT Creator as admin, but the error is still occuring.

hskoglund

Just to be sure it crashes in the test.load() statement, if you add a qDebug() directly after, you don't see any output from it in Qt Creator, like ...*QImage( ..." etc.? Say like this:

#include "mainwindow.h"

#include <QApplication>
#include "qdebug.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    QImage test;
    test.load("C:/IMAGES/IMAGE.png"); // crashes program
    qDebug() << test;
    w.show();
    return a.exec();
}

@hskoglund I tried that and the program seems to just stop and crash when I load (without displaying anything in the console with the qDebug). I also tried to qDebug a basic message after the load, but it doesn't seem to print that either.

hskoglund

When you mentioned you're using LLVM MinGW 64, is that the MinGW 11.2.0 64-bit compiler that can be installed via Qt's Maintenance app?

bapcruz

@hskoglund Yes. I also have MinGW installed separately on my computer so I could try quickly making another kit with those and see if it works.

Edit: Changing the version of MinGW in the kit worked! I tried using regular MinGW 64-bit and that made it work perfectly. Thanks so much
