I don't catch exception in Qt

  • I've encountered a big surprise for me.
    My program doesn't catch any exception (in particully in main function ) when qt libraries have been included.
    I googled this problem and didn't find an answer.
    Please explain me:

    1. Why this happens ?
    2. How to bypass this ? I use a combination of libraries in software development (stl, boost, opencv) and i cant develop software, applying ONLY QT.
      QT version - 5.2
      Mingw 4.8 and 6.02

    .pro file

    # Project created by QtCreator 2018-04-28T23:53:47
    QT       += core gui
    greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
    TARGET = qt_eception
    TEMPLATE = app
    SOURCES += main.cpp
    HEADERS  +=
    FORMS    +=


    #include <QApplication>
    #undef main
    int main(int argc, char *argv[])
            QApplication a(argc, argv);
            throw "ex";
            // Do Nothing
        return 0;

    Qt should not have any effect your your ability to use exceptions.
    Tried your sample on win 10 , vs 2015 compiler and it works.

  • @mrjj I don't have any problem with exception, if i don't include and don't apply Qt library. I use Qt creator 3.0.0 and windows 7. Can you advise me, where start to research this problem ?

    When you dont "apply Qt library. " can it be its other compiler or
    setting that is being used ?
    What compiler are you using ?

    @Petin, does your program run correctly if you don't throw an exception?
