Filed a bug to clarify the message in the target setup page: http://bugreports.qt.nokia.com/browse/QTCREATORBUG-5248

You do not have a tool chain set up that Qt Creator can use to build stuff using the Qt version you have defined. It is not possible to mix a Qt build with MSVC2008 with binaries build with MSVC2010, so that is not offered.

Please either downgrade your compiler to MSVC2008 or set up a Qt version build with MSVC2010. I know this sucks, but there is little we can do about this (except to improve the error messages in Creator of course).

or can he get qt libraries built with minGW , download minGW tools , and then use it them in qt creator..
this way don’t need to compile the sources??????

One drawback is you can not use VisualStudio to develop / debug qt apps.

WRRR

It’s freaking impossible. I have just uninstalled msvc version and installed this one for mingw and… the same seg fault as I had in the beginning….

So, you get a SIGSEV when running. That can have a lot of reason (in fact, it’s the most common error you’ll get). What program did you try to run? What you could also try is to “Clear System environment” in the Qt Creator project settings (to make sure you use the correct libs).

I just try to make an “empty” project (with wizard) and then while I build it I get this error. Talking about clearing system environment: how can I do it ?

If you go in “Projects” mode in Qt Creator and click on “Details” under “Build Environment”, there’s a checkbox. Also, It does not crash while you build, it crashes when you run it. (The “green arrow” builds and then runs your application). If that doesn’t work, rebuild you application (you can do that in the “Build” menu) and see if there are any compile warnings.

Ok so I have cleared system environment and I have noticed one thing: it does not throw a seg fault while compiling but when running in debug mode. I can launch my app normally with “run” button (green arrow : ctrl + r) but I cannot do this with f5 (seg fault).

Looks like you are not alone here…. searched for guard32.dll and I found few people facing same problem with Qt Creator while debugging…

Are you using Comodo Firewall??? Seems related to that..

  1. The  only problem so far is, that I can't debug with it at all as long
  2. as  the COMODO Firewall's 'Defense+' is active. This installs a system
  3. hook  via  C:\WINDOWS\system32\guard32.dll  which is invoked everytime
  4. any  application  is  launched. This seems to confuse either gdb or Qt
  5. Creator  so that when I want to start debugging it halts in that file.
  6. I  can't  contine,  step over/out or do anything that seems to have an
  7. effect.
  8. Disabling the entire Defense+ mechanism was the only way I could find
  9. to overcome this (which requires a restart to remove the hook).

The Qt version configuration page now warns when not all required tool chains are available. That should make debugging the original issue way easier. The code will be in 2.3 (which will get a beta release in a couple of weeks, now that it is feature frozen).

I am indeed using Comodo internet security but I have turned off defense+, restarted and then the same seg fault over again. I think I will have to resign from debugging and just try to be lucky with normal compiling for now (which is kind of silly).
