Qt compilation error: Project ERROR: Unknown module(s) in QT:xxxxx

Introduction to all qt modules

Solution:¶

Only installed when installing QT5

sudo apt-get install qt5-default
sudo apt-get install qtcreator

Some modules are not installed and need to be installed manually: for example, the pro file adds: pro+=serialport, the compilation error says: Unknown module(s) in QT:serialport

sudo apt-get install libqt5serialport5
sudo apt-get install libqt5serialport5-dev

The format behind install is: libqt5xxxx5: where xxxx needs to be replaced.
