[How To] How to debug in Qt Creator 3.2 with Win 8.1 + Qt 5.3.2 + VS 2013 Upd 3
Recently I installed in a Win 8.1 box with Visual Studio 2013 Update 3, Qt 5.3.2 with web installer. Selected all boxes related with VS2013, Sources box, and Qt Cloud box.
Created a simple Qt application (just a button saying "Hello"). Worked. ¡Good!!
Tried to debug it... no luck. "No debugger set up" appeared in screen. Looking at the kits (Tools, Options, Build&Run) for VS2013, I noticed that "Debugger" field was empty and disabled (thus with no option to edit it).
The official page was not clear enough for me "Setting Up Debugger":http://qt-project.org/doc/qtcreator-3.2/creator-debugger-engines.html. Googling and googling took me into this forum post that gave me the final hint: "How to debug projects under Qt 5.1/MSVC2012":http://www.qtcentre.org/threads/55502-How-to-debug-projects-under-Qt-5-1-MSVC2012
So, in order to get debugging, you must install a WDK (this includes the Windows Debugging Tool and the Microsoft Symbol Server). You can get it at: "WDK download":http://msdn.microsoft.com/en-us/windows/hardware/hh852365
I installed the WDK 8.1 Update, and now Qt autodetects the debugger and I can debug my projects. Be warned: it takes 1,1 GB of space. Perhaps you may consider to install only the Debugger Tools and MS Symbol Server, available in the same page.
I hope this was useful to others stucked in same situation I was.
