[pyqtdeploy] Failing at building the demo

Sat Apr 20 14:57:37 BST 2024

 -lQtMultimedia means that you are linking with QtMultimedia.so.

The first thing you do is check is your /usr/lib directory whether that
file exists: cd /usr/lib && find | grep -i qtmultimedia

Then if the file is not found, you check the list of files your
qtmultimedia5-dev package has. You'll see that it has Qt5Multimedia.so.

So then what you need to do is just symlink it

ln
-s /usr/lib/x86_64-linux-gnu/libQt5Multimedia.so
/usr/lib/x86_64-linux-gnu/libQtMultimedia.so
