c++ - My program has unexpectedly finished

Question

this simplest program gives error when compiled in release mode, but compiles fine in debug mode:

#include <QApplication>

int main(int argc, char* argv[])
{
    QApplication app(argc,argv);

    return app.exec();
}

ERROR (output from qt's console)

*Starting C:excercizesQT_projectsLine_Counter-build-desktop-Qt_4_7_4_for_Desktop_-_MinGW_4_4__Qt_SDK__Release eleaseLine_Counter.exe... The program has unexpectedly finished. C:excercizesQT_projectsLine_Counter-build-desktop-Qt_4_7_4_for_Desktop_-_MinGW_4_4__Qt_SDK__Release eleaseLine_Counter.exe exited with code -1073741511*

Anyone had this experience?

Answer 1

Value -1073741511 is 0xC0000139 hexadecimal, which is error code STATUS_ENTRYPOINT_NOT_FOUND. This means that some DLL is loaded by EXE or another DLL, but it lacks a function that EXE or another DLL is expecting there.

Event Viewer may show you what DLL is lacking what function when the error occurs. Dependency Walker will also show you this, and the whole DLL structure as well.
