遇到的问题
FactoryLoader::QFactoryLoader() checking directory path "/home/tage/Exec/qt57_tage_sensor_calibration_20210705/calibration/platforms" ...
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".
Reinstalling the application may fix this problem.
实际上是找不到platform 平台。建立一个软连接就可以,
sudo ln -sf ~/Exec/Qt5.7.0/Tools/QtCreator/lib/Qt/plugins/platforms/ /home/tage/Exec/qt57_tage_sensor_calibration_20210705/calibration/platforms
其中~/Exec/Qt5.7.0/Tools/QtCreator/lib/Qt/plugins/platforms/
是安装的Qt的位置。/home/tage/Exec/qt57_tage_sensor_calibration_20210705/calibration/platforms
是我要运行的软件的位置。
