what is the meaning of "qrc::-1 File is empty"

[hcaslan]

I'm trying to learn qt and I encountered such an error in my project, but I couldn't find any examples. Can you help?

QmlApplicationEngine failed to load component
qrc::-1 File is empty

my code at main.cpp

#include <QGuiApplication>
#include <QtQml/QQmlApplicationEngine>

int main(int argc, char *argv[]){
QGuiApplication app(argc,argv);
QQmlApplicationEngine engine;
engine.load(QUrl("qrc://main.qml"));
return app.exec();
}

my code at main.qml

import QtQuick 2.0
import QtQuick.Controls 1.0
import QtQuick.Window 2.0

ApplicationWindow{
width: 640
height: 480
visible: true

Text{
    anchors.centerIn: parent
    text: "hello world"
}

}

I found my mistake. I made a mistake while typing the QUrl(it must be three / not two / ). Thanks for your concern. If someone hadn't answered, I would probably have given up.

Hello and welcome to Qt forum!

engine.load(QUrl("qrc://main.qml"));

With this, you want to read main.qml file from resources (cf. https://doc.qt.io/archives/qt-5.11/resources.html).
Do you have add a resources to your project?
Is this file part of this resource?

[hcaslan]

@KroMignon Yes ı created and added the file "main.qml".

Yes ı created and added the file "main.qml".

And is the resource part of your project?
Do you use cmake or qmake build system?
Which Qt version are you using (I mean Qt and not QtCreator)?

[hcaslan]

@KroMignon cmake build system. And ı use QtCreator. ı have tried this to add resource --> Add new>qt>resource file then add prefix then add files. if that's what you're asking.
