Hi,

The .pro file with your project name contains the QT statement you should add “multimedia” to. qmake is always run automatically by VisualGDB when building.

Hi,

Based on this log and the line “warning : unknown QT: multimediawidgets”, you need a space in between i.e. “multimedia widgets”.

Based on “/usr/bin/ld: cannot find -lQtMultimedia”, libQtMultimedia cannot be found by the linker. Please verify that libQtMultimedia is installed on your Raspberry Pi (should be somewhere in /usr/lib where the other Qt libraries are).
As other Qt libraries are found, the standard Qt package for Raspberry Pi may not include it and you should install it separately. You may also need to build the library yourself if it is not available anywhere.
