      @dheerendra At this point, we are fairly certain that the problem is in the main thread code. I have uploaded the main thread code in the previous comment. Please suggest any necessary changes that could solve the issue. thank you.

      If you want to compile from source, you need to follow the steps described here: http://doc.qt.io/qt-5/build-sources.html Thanks, I am trying this now. The compilation completed successfully, after I had configured with -qt-xcb (otherwise there would be an issue with library xcb-sync). Thanks @aha_1980 for the advices !

      @jsulm there was in fact a problem with window3d() that MinGW didnt complain about! Thanks! @JonB no I had commented out only up to the second screenshot, so that's why this was the problem. And about the second issue, to be honest I adapted the constructor from an older version of the application and it also had &argc. At one point I also noticed it and now I tried out both and both work.

      @JonB Do not misunderstand. I have not said that I will not try your solution. I have just explained my temporary approach that I'm currently using to find the origin of my crashes. For the future I will take time to investigate more with the hope to have a generic solution to apply on all my VS solutions.

      @Wael11 For anyone reading this: This is known behaviour, which I stumbled across a long time ago and it was infuriating. With a QSpinbox Qt Internal code uses a timer on clicks/presses. If you step through in debugger you exceed the timeout and get bad/double behaviour. Simplest: change all connect() to QSpinbox click/key to pass Qt::QueuedConnection as last parameter for connection type, not default Qt::DirectConnection. Now you can use debugger breakpoints and all will be well. I wrote a method to connect all my spinboxes like this.

      Then do you mean: does Qt provide a way to read this tag ? Or are you looking for which widget can show the content once you got the data ?

      @bogong For me it's normal develop qt (also for mobile application), but in this time I must develop a strange case, I must use a native controller (that it can't be emulate in qt/qml) and from this I must start the qml GUI. It's all ok, I see the qml elements but I can't catch the user interaction, not press button, nothing. I started from Qt project where I added native object-c files, AppDelegate, other native controller, etc.

      @Randomator Sir, download the Qt Sources, e.g current the sources available are qt-everywhere-opensource-src-5.5.1, After extracting cd C:\qt-everywhere-opensource-src-5.5.1\qtbase\src\plugins\sqldrivers\mysql then make sure you call qmake from Qt5.5, for this purpose you can type the complete path of the qmake. then use make and make install. I hope it will help you.

      Both your classes need to inherit from QObject for the signal/slot mechanism to work. Code blocks are either preceded by 4 spaces (good for one liners): int variable; or they can be enclosed by `` ` (triple back ticks, good for inline elements and longer blocks): #include <iostream> int main (int argc, char * argv[]) { std::cout << "Hello, World!\n"; } Google Markdown syntax for some more markup details.

      @swhweng Well, you would need to implement the POSIX standard (or at least parts of it) on FreeRTOS. This is, for sure, a very complex task :-)

      I figured it out. I needed to set my QObject and QCore stuff properly. In the .pro file of the shared library, I added: QT += core In the shared library's .h file, I switched this: class CTSCANSHARED_EXPORT ctScan { public: ...blah blah... with this: class CTSCANSHARED_EXPORT ctScan: public QObject { Q_OBJECT public: ...blah blah... And then ensured the shared library's .h file had this: #include <QObject> And then it compiled properly.

      Another interesting development: I tried running on another machine with the Qt toolchain installed, and the program worked. So it appears it is still reading something from the filesystem that is not on a regular Windows machine, but I don't know what that might be. I did package all the qmldir files needed for Qt Quick to work.

      By the way, I found that the Intel Core 2 Duo CPU T7500 is a 64 bits one. I have installed Ubuntu 32 bits because there was no added value for me to install a 64 bits one. for some compatibility reasons I kept also a 32 bits one when I started to use Ubuntu 4 years ago Do you think that it could potential be the source of the problem or it doesn't matter?
