Сan't use QtMultimedia in the project

Samovolk

Hello all!
I need to add the ability to work with mp3-files. To do this I specify #include <QMediaPlayer> in the project. But the project does not compile and displays the following error

error: QMediaPlayer: No such file or directory
        #include <QMediaPlayer>

If I create a new clean project and specify "multimedia" in the .pro file, i.e. it turns out this line

QT + = core gui multimedia

then if you build the project, then pop up this errors

error: cannot find -lQtMultimedia
error: collect2: error: ld returned 1 exit status

All the solutions that I saw with QMediaPlayer did not help me. I can’t determine where the problem, so I need someone's help.

@Samovolk How did you install Qt and which version?
On which OS?

Samovolk

Oh, I definitely forgot it. OS - debian 9.
Installation was done through Synaptic. Installed: qt-sdk and qtcreator. Everything else was installed automatically. Qt version is 4.8.7.

Hi,

AFAIR, QtMultimedia is a Qt 5 module.

In any case, unless you have strict constraints, you should pass to Qt 5.

I knew it. Google confused me and I thought that the problem is not in the version. Updated to version 5 and it worked.
Thanks for help.
