  Hi

  This is a solution to fix the problem on Raspberry Pi 3 with Qt 5.8

  open the bashrc: $sudo nano ~/.bashrc in the file add:
  export QT_QPA_EGLFS_PHYSICAL_WIDTH="230mm"
  export QT_QPA_EGLFS_PHYSICAL_HEIGHT="180mm"
  tip: you can try with different size, in my case I've got a display of 7" but I configure with 11.6" and looks great, the size you can check in: https://en.wikipedia.org/wiki/Display_size save the file $sudo source ~/.bashrc

  In Qt Creator ever show the error when compiling is normal, but when you run your application from console the error's gone, other tool help the application, look better use qt5ct help a lot.

  @J.P-Jon said in Run Qt 5.3.0 on QNX 6.6:
  Hi,
  I'm trying to run Qt widget application on QNX 6.6 target. However, the following error occurred:

  Dec 31 19:12:14.974 Test.528403 default* 9000 QQNX: failed to open navigator pps, errno=2

  Dec 31 19:12:14.974 Test.528403 default 9000 QQnxVirtualKeyboard: Unable to open "/pps/services/input/control" for keyboard: No such file or directory (2).

  Dec 31 19:12:14.974 Test.528403 default 9000 QQNX: failed to open buttons pps, errno=2

  My test program is very simple:
  #include <QApplication>
  #include <QLabel>
  int main(int argc, char** argv)
  {
  QApplication app(argc, argv);
  QLabel *label = new QLabel("Hello World!");
  label->show();
  return app.exec();
  }

  The environment variables are set as follows:
  export QT_PLUGIN_PATH=/opt/plugins
  export QML2_IMPORT_PATH=/opt/qml
  export QML_IMPORT_PATH=/opt/qml
  export QQNX_PHYSICAL_SCREEN_SIZE="150,60"
  export QT_QPA_FONTDIR=/opt/lib/fonts
  export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/graphics/iMX6X

  Regards,
  J.P

  I have found the proper solution to this problem. It's not the moc per se, it's how the generated cpp file is linked in the binary.
  Anyway, without going into the ugly details, to solve this, one must simply include the generated moc_xxx.cpp file into the regular class's implementation .cpp file.
  In my case I had to include moc_aedmpimessages.cpp in aedmpimessages.cpp to make it work correctly.

  Hello @Chaimae,

  You can create a third plugin Z containing only your common qml files, then you import it from another qml in plugin X or plugin Y.
