    That part looks good.

    What about the content of gcc_x64 lib and plugins folders ?

    @SGaist

    There are so many, about 600, files in the gcc_64 lib. What kind of files should be in the directory?

    Plugins folder has these folders:

    • assetimporters
    • audio
    • bearer
    • canbus
    • designer
    • egldeviceintegrations
    • gamepads
    • generic
    • geometryloaders
    • geoservices
    • iconengines
    • imageformats
    • mediaservice
    • platforminputcontexts
    • platforms
    • platformthemes
    • playlistformats
    • position
    • printsupport
    • qmltooling
    • renderers
    • renderplugins
    • sceneparsers
    • sensorgestures
    • sensors
    • sqldrivers
    • texttospeech
    • virtualkeyboard
    • wayland-decoration-client

      This is how I installed web engine module. It may be helpful for you.
      git clone ​https://code.qt.io/qt/qtwebengine.git
      cd qtwebengine
      git checkout 5.15.2 ==>match the Qt version installed
      git submodule update --init --recursive
      mkdir build
      cd build
      qmake ../qtwebengine.pro -- -no-build-qtwebengine-core ==>core engine build has been installed, no need to rebuild
      make -j4
      sudo make install ==>automatically to the installed location of Qt-5.15.2

      Thank you for your advice. I tried $ git clone git://code.qt.io/qt/qt5.git and $git checkout and so forth.
      At the point at make -j4 errors came, which said

      qt5/qtmultimedia/src/multimedia/qmediacontrol.cpp:136:10: fatal error: moc_qmediacontrol.cpp: No such file or directory
        136 | #include "moc_qmediacontrol.cpp"
      

      So I am doing $ https://code.qt.io/cgit/qt/qtmultimedia.git.

        The idea is that you look for the multimedia library and the plugins. The former should be something like libQt5Multimedia.so and you should have a subfolder named multimedia in the plugins folder.

        Note that if you do not have the GStreamer development libraries installed, you won't have much in the multimedia part.

        Did you do that from a clean state ?

          Now Qt folder has multimedia and the install done:

          $git clone https://code.qt.io/cgit/qt/qtmultimedia.git
          $cd qtmultimedia/
          $git checkout 5.15.2
          $git submodule update --init --recursive
          $cd ../qt_build
          $qmake ../qtmultimedia/qtmultimedia.pro --
          $make -j4
          $make install
          

          No error happened but still error: Qtmultimedia/QMediaPlayer: No such file or directory occured.

          Note that if you do not have the GStreamer development libraries installed, you won't have much in the multimedia part.

          No, I haven't installed GStreamer development yet...

            No, the Qt folder was not cleaned. Should I re install Qt creator and clone https://code.qt.io/cgit/qt/qtmultimedia.git?

              After installation, you will be able to find this.
              5.15.2/gcc_64/include/QtMultimedia
              In the .pro file, add multimedia
              QT += core gui widgets xml multimedia

                Hello,

                5.15.2/gcc_64/include/QtMultimedia

                Yes, I can find it.

                I uninstalled Qt creator and reinstalled it. Then I did:

                $git clone https://code.qt.io/cgit/qt/qtmultimedia.git
                $cd qtmultimedia/
                $git checkout 5.15.2
                $git submodule update --init --recursive
                $cd ../qt_build
                $qmake ../qtmultimedia/qtmultimedia.pro --
                $make -j4
                $make install
                

                No error has come. I wrote

                QT += core gui widgets xml multimedia

                in .pro file and #include <Qtmultimedia/QMediaPlayer> into mainwindow.h file.
                But IDE says "Qtmultimedia/QMediaPlayer not found" and "You need to set an executable in the custom run configuration".

                What am I missing?

                  It's QtMultimedia.

                  However, the use of the module prefix recommandation has been dropped since Qt 5.0 if not before.

                          @nrml When Qt is installed, there is an option to select multimedia for installation. It is not necessary to install it separately. But now you know how to install a component which may be required in Qt6

                            When Qt is installed, there is an option to select multimedia for installation.

                            I used an installer which is from Open Source Qt Use but there was no option to multimedia. There, however, is an option to "Additional libraries->Qt->Active Qt, Qt 3D, Qt Charts and so forth" in Maintain Qt.

                              When Qt is installed, there is an option to select multimedia for installation.

                              I used an installer which is from Open Source Qt Use but there was no option to multimedia. There, however, is an option to "Additional libraries->Qt->Active Qt, Qt 3D, Qt Charts and so forth" in Maintain Qt.

                              @nrml download qt-unified-linux-x64-4.0.1-online.run from ​https://download.qt.io/official_releases/online_installers/
                              use the latest one. Remove the old installation and try the new one. Install it in a location which can be found easily.
                              Usually /opt is the right choice.

                                Also Qt 5.15.2 has some components like them. Is the multimedia included one of them?

                                    QtMultimedia is not an optional package, it's part of the standard installation with Qt 5. For Qt 6, it shall be back for 6.2.

                                    If it's not there with 5.15.2, then try either with 5.15.1 or if you have a commercial license a later version.

                                      There is no Qt Multimedia package in both 5.15.2 and 5.15.1...

                                        @nrml Because, as I wrote, it is part of the standard set of installed modules.

                                          Okay... so if I install Qt, it should be installed as default?
                                          Hmm... then why cannot my qt creator find the file?

                                          Path problem? I am installing qt in /opt directory and try run the code again once it done.
