Problem Building Qt C++ Examples

[quote author="Alexander Kuchumov" date="1291307762"]Try to set env PATH to directory with qtdll's.[/quote]
It seems that compiler cannot find libs, not dlls. Maybe, something wrong with *.a file location (or how iit is called in mingw), spaces in the path or LIB value in *.pro file?

Thanks all for your replies. Unfortunatly, it didn't help me any further.
I wanted to evaluate Qt, and given the fact that after a default installation on XP I can't build the included examples is a bit frustrating and definatly not what I expected. So currently thumbs down on Qt, but I don't give up yet!
In the environment settings, I've added C:\Qt\2010.05\qt\bin to the PATH. Further I noticed that in Projects -> Run settings one can make also change the build, clean and environment settings, but I am not sure what to look for here what could be wrong...
Any further help appreciated.

I have just compile you example using QtCreator but from build 2010.01
Instead of make try the IDE:
- open project in QtCreator,
- select the proper version of Qt (Tools - Options - Qt4 - Qt Versions - Default Qt version): in your case it should be c:\qt\2010.05\qt\bin\qmake.exe
- Build - Run qmake
- Build - Run

Just noticed the topic header. If you can correct it - its Qt and not QT(Quick Time)

I'm having the exact same problem and I cannot figure it out for the life of me. I went as far as to put the lib directory into the system path and I am still unable to compile the example applications.
Below is the compile output. I was able to get it to compile once. Then I took the lib dir out of the path to make sure that was the solution and I haven't been able to get it to compile since. I have no idea whats wrong and I'm pretty disappointed that the default installation does not work. Any help would be appreciated.

The problem appears to be caused by the lib C:\Program Files\Microsoft Visual Studio .NET 2003\SDK\v1.1\Lib\
Please check your system properties -> Environment settings on your Windows machine. Likely there is a variable with name LIB listed and which has the value C:\Program Files\Microsoft Visual Studio .NET 2003\SDK\v1.1\Lib. Delete this entry and try again to run qmake and to rebuild the application.
This was what caused my problem as well.

Thanks, that got me a bit futher but then i ran into another known problem -> http://bugreports.qt.nokia.com/browse/QTCREATORBUG-1889
I was eventually able to get past this but why hasn't this been bug resolved? Should I reopen this bug? This is experience does not leave a good impression especially as a first time user.
