Building on Linux Mint (Ubuntu 24.04) fails due to QAudioSink

[andimik]

I'm running Linux Mint which is based on Ubuntu 24.04.

Due to the fact that the AppImage does not work, I wanted to build it (both master and next branch) from sources (both with qmake and QtCreator), but it seem I needed to install some additional packages (which are not mentioned on your Readme, obviously), otherwise I get the following error:

make
cd src/welle-gui/ && ( test -e Makefile || /usr/lib/qt5/bin/qmake -o Makefile /home/andreas/apps/welle.io/src/welle-gui/welle-gui.pro ) && make -f Makefile 
Project MESSAGE: Current git hash = 6a1adf03
Project MESSAGE: BUILD_DATE = 1728505781
Project ERROR: Unknown module(s) in QT: quick qml charts multimedia
make: *** [Makefile:47: sub-src-welle-gui-make_first] Error 3

sudo apt install qtdeclarative5-dev qtmultimedia5-dev libqt5charts5-dev

But then I got the error:

In file included from ../../../src/welle-gui/radio_controller.h:45,
                 from ../../../src/welle-gui/main.cpp:44:

   36 | #include <QAudioSink>
      |          ^~~~~~~~~~~~
compilation terminated.

see https://doc.qt.io/qt-6/qaudiosink.html

The funny thing is, that this line is from 2022 (see https://github.com/AlbrechtL/welle.io/blame/a910d9d2f8116aa84d476eb39efa1c24ccb4b429/src/welle-gui/audio_output.h#L36 ) and I remember I could build it on my previous Ubuntu installation.

Then I checked if there is a file already on my system:

andreas@E535:/usr/include/x86_64-linux-gnu/qt6/QtMultimedia$ ls -l | grep QAudioSink
-rw-r--r-- 1 root root   24 Dec 12  2022 QAudioSink

If you need that:

qt6-multimedia-dev is already the newest version (6.4.2-11build3).

BTW: I could build it with cmake, but then the app is only visible as icon in the start menu.
