Is it normally slow when debugging with GDB on Windows?

Installed.

What! It's really fast even it's connect to Microsoft symbol server
but what it this? What if I don't have internet connection?

And what do you mean?
I should not install "Qt 5.3.1 for Windows 32-bit (VS 2013, OpenGL, 557 MB)"?
Should I install "Qt 5.3.1 for Windows 64-bit (VS 2013, OpenGL, 571 MB)"?

My OS is Windows 8.1 64-bits

bq. Be aware the installing the 32 bits on a 64 bits computer will make it extreme slow!! So maybe that is kuzulis his problem.

No, I have 32-bit OS, unfortunately.

I had this issue at one point. Do you have previous versions of the compilers installed? I used MSVC2010 compiler for a while with QtCreator and it was slow as death on 8.1. It was taking 10 seconds to step.

After uninstalling all of the previous compiler versions and moping up everything, I just installed 2012 first, then 2010, and everything debugs fine now (I can switch between the two with the same performance).

If I remember correctly, there is some information on microsoft's help pages that gives a recommended order on how to install different versions of the compilers.

2 dvez43,

At me at first MSVC2012 was installed. After some months I installed MSVC2010 in addition to. Therefore, apparently, a problem not in sequence.

PS: Just it is a black magic. :)

I have this problem too. The debugger is unbearably slow.

I am running Win 8.1. I have QT Creator 3.2.2 based on QT 5.3.2.

I have the latest WinSDK installed, and Visual Studio 10 Professional.

When I go to Projects/Build & Run/Debug configuration, it says it builds to this directory: ...Desktop_Qt_5_3_MSVC2010_OpenGL_32bit-Debug.

That implies it is running a 32 bit debugger. Under Projects/Build & Run/Manage Kits/Build & Run it says it auto-detects both x86 and x64 debuggers. So it knows I have a 64 bit debugger. How do I make it use that one?
