Error when executing Qt application on Win7: possible issue with libstdc++-6.dll?

Is "Access violation" as a quick Google search will tell you. The code is almost certainly accessing a zero, uninitialised, or already freed pointer.

You also need to complete the deployment with the MingW runtime library (MINGWM10.DLL), "platforms/qwindows.dll" plugin for Windows, and the ANGLE related dlls (3 of them I think). Do that first as you will not get much further without them.

Thanks for your help!

I've added all the .dlls, but I am still getting the same error.

I tried to proceed in a different way: I loaded my .pro in Qt Creator, I cleaned/re-built it and I tried to run it from there...but again, I got the same error.

EDIT: As a comparison, I also tried to run some programs from the "examples" folder in Qt/5.1.1, and Qt Creator was able to load, compile and execute them correctly.

What could be the issue?

Yes, because these programs do not have any "Access violation" bugs. Run debug version of your project under debugger and post stack trace after the crash.

Ok, I ran the Qt Center debugger, and here is what I got (see attached screenshot)

"Level 0" in the window is libstdc++-6.dll inside the folder where the executable is.

Can you post the content of main.cpp ? Line no. 12 in particular
