Assert failure in QCoreApplication

Mahima

Hi All,

I have using Qt 5.1.1 in Visual studio 2008. But I am getting Assert failure in qcoreapplication.cpp at line 699.

Q_ASSERT(QCoreApplicationPrivate::eventDispatcher != 0);

Do any one is having idea what is going wrong or how I can fix this issue ?

Following is the call stack :

Qt5Guid.dll!0f9d9daa()
[Frames below may be incorrect and/or missing, no symbols loaded for Qt5Guid.dll]
Qt5Widgetsd.dll!646b4d80()
Qt5Cored.dll!QCoreApplication::init() Line 699
Qt5Cored.dll!QCoreApplication::QCoreApplication(QCoreApplicationPrivate & p={...}) Line 628
Qt5Guid.dll!0f9d80a4()
Qt5Widgetsd.dll!6463ac3c()

How are you instantiating the Q*Application in your code?

Hello
You have two solutions :
Copy theses dll (Qt5Guid.dll ...) next your exe
Add in your sytem PATH the path where theses dll are ..

Because your programm search theses dll

PS : sorry for my english :-)

Not very likely since the assert is triggered inside Qt's library

Thanks for your reply.
I compiled Qt myself and forgot to add windows.dll in plugins->platforms. When I added the same, it ran successfully.
