Hello,
Are your qmake and Qt libraries compiled with the same comiler? If not this is the reason you get the undefined references. MSVS and mingw use different decorations and are not binary compatible.Kind regards.

@kshegunov is there any reference documentation where in qt installation on windows 7 is present.

@babravahan
Just look up what you've installed in the "Qt maintenance tool", there are a few checkboxes for different versions/compilers, look at what you've checked.Or try to get that from qmake, runningqmake -vshould give you the Qt version and the compiler used.Kind regards.
