Failure when building QT on Windows with MinGW

[jpn]

I'd suggest using the version of MinGW that is bundled in (or actually downloaded by) the binary installer of Qt. It's guaranteed to work nicely along with Qt.

yes you are right. when downloading the mingw during the installation of QT opensource,the installation application maybe zombie,but it still downloads the Mingw completely ,and you can find that setup files at download archive,then you must cancel the QT installation,and install MingW which locates at c:\qt4.4.2\download.After you install MingW,you can install the QT library without downloading MingW.
It's my tip.Hope this tip can help you.
