QApplication does not work with Qt5.11.1 build on RPi
-
Hello,
I want to build the Modbus application using the QT platform on my Rpi .
I have following environment and setting are there for QtCreator and Qt.
QtCreator 4.2.0
Qtkits setting :
Qtversion : 5.11.1
when i run the below code :
int main(int argc, char argv[])
{
// TODO uncomment this line before release
// right now we always need it
QLoggingCategory::setFilterRules(QStringLiteral("qt.modbus = true"));
QApplication a(argc, argv);
MainWindow w;
w.show();return a.exec();}
it get stuck and exit the code at "QApplication a(argc, argv);" line ...
what I got at output windows is :
