wrong library or version mismatch when opening QSerialPort

Hi,
I am developing a GUI application in QT5 on Ubuntu host PC for an embedded device running Yocto, and I succesfully added the QSerialPort module to my project.
In my mainwindow.cpp, at the startup, I'm trying to call a routine which initialize the serial port in this way:mainwindow.h:
public: QSerialPort *serialport;mainwindow.cpp:
MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); ... serialport->setPortName("/dev/ttymxc2"); serialport->setBaudRate(QSerialPort::Baud9600); serialport->setDataBits(QSerialPort::Data8); serialport->setParity(QSerialPort::NoParity); serialport->setStopBits(QSerialPort::OneStop); serialport->setFlowControl(QSerialPort::NoFlowControl); if (serialport->open(QIODevice::ReadWrite)) { // OK } }The problem is that when the serialport init section is present and uncommented, the application does not start at all, and the "application Output" window in Qt Creator shows the following:

Could not load shared library symbols for /usr/lib/libxshmfence.so.1. Do you need "set solib-search-path" or "set sysroot"?File "/opt/fslc-x11/2.2.1/sysroots/armv7at2hf-neon-fslc-linux-gnueabi/usr/lib/libstdc++.so.6.0.22-gdb.py" auto-loading has been declined by your `auto-load safe-path' set to "$debugdir:$datadir/auto-load".I'm not sure it's this related to the serialport initialization.. Anyone has any idea how to fix it?
Many thanks! -

@jsulm
I did not specify this (if it can be useful): I am cross-compiling for my device.
Browsing the target device, I can see the following libraries under /usr/lib:
so I suppose the serialport module version is the 5.9, right?
In my kit, the Qt version displayed is 5.7.1, so it seems to be different from the serialport module. Can this be the problem?To include the serialport module in my project, I added "QT += serialport" to my .pro file.
Am I missing something?
Thank you. -

@jsulm My application should run onto the target device (i.MX 6UL processor), not on the Ubuntu PC.
That error came out when I try either to run the application directly from my target device and from the QtCreator Debugger.
The GUI doesn't appear on the device display, and the Application output console shows that error. -

@douglas I didn't say it has .exe extension. YOUR_EXE_FILE is simply a placeholder for the name of your executable file as I don't know it.
Another question: do you use same Qt version to build your app and to execute it on your target? On your target you have Qt 5.9.2 but you said on your PC you have 5.7.1 right? If it is the case you need to make sure you use exactly the same Qt version. -

Yes, it seems to be right. How can I align the libraries version?
Thank you! -
@douglas Take a look at http://doc.qt.io/qt-5/linux-deployment.html
And the question is: which version do you actually want to use?
