Help : Segmentation fault when using a 3rd library

Since you are using MinGW, your should already have a debugger then just click on the other green arrow, then one with the little bug, you should get more information

Application Output:
Debugging starts
can't find linker symbol for virtual table for 'QApplication' valueThere are many warnings. Some read 'ignoring #pragma comment' while others 'unused parameter'. What is the problem?
-
Did you download the MinGW version ? If so, it's been compiled with MinGW 4.6.2 which is not compatible with 4.8

Oh, I am now using Qt creator 5.2.0 and MinGW4.8. How can I reduce MinGW to a 4.6.2 version?
-
You would need to install it by hand and also recompile Qt with it
-
However, the download page also mention that you can request a build, so you could try to ask them about a version using MinGW 4.8

Thx for your reply! I have downloaded Mingw32 4.6.2, but I want to ask how to recompile Qt with it.
-
Just follow the "documentation":http://qt-project.org/doc/qt-5/windows-building.html
However, I would recommend trying to ask a build for MinGW 4.8

I've tried to follow the instruction, but it is complex for me. I just copied and pasted MinGW4.6.2 in the directory, and compiled the program. Now it stops at the very beginning and the Application Output window says

Did you also compile Qt with that version of MinGW ?
