Using QTextToSpeech causing multiple definitions errors

[Suroh6]

I was trying to follow the example code for QTextToSpeech from https://doc.qt.io/qt-5.10/qtspeech-hello-speak-example.html
I modified it slightly but not in a way that should've broken anything. I get the following error when running the below code.

Multiple definition of `Example::Example()`
In function `QTypedArrayData<QVoice>::sharednull()`:

This error occurs five times and references the same thing. Can anyone explain what's happening?

#include "QTextToSpeech"
class Example
{
    public:
        Example();
        void speak(QString &words);
        void stop();

        void set_rate(int r);
        void set_pitch(int p);
        void set_volume(int v);

        void state_changed(QTextToSpeech::State state);
        void engine_selected(int index);
        void language_selected(int lang);
        void voice_selected(int index);

        void locale_changed(const QLocale &locale);


    protected:


    private:
        QTextToSpeech *example_speech;
        QVector<QVoice> vector_voices;

};

Example::Example()
{

}

Hi
The implementation IS in the cpp file ?
Example::Example()
{

}
and not under class in .h as that would give multiple defines errors

Sorry, I didn't realize that I didn't paste everything. Yes, it was in there, turns out for some reason there were multiple inclusions of the header and cpp in the .pro, once I removed those it took the errors away. I think it occurred when I modified it outside of the editor. I'm going to close this out!

Ah, yes its a classic. If you use the New Class dialog and overwrite files
this can easy happen.
