Hello Could you post the backtrace that you get? Which compilation options did you use? Also, since you're using Windows, can you tell us if you have other versions of MinGW, Cygwin or Dev-C++ installed? > Having spoken with a second colleague I was informed that Qt 4.7 doesn’t > build with MinGW, at least not without some Makefile hacking.

We have some problems with MinGW in that the compiler crashes while compiling Qt. Sometimes, moving the code around fixes the issue (or hides it). As Qt 4.7 development is still at a fast pace, these issues pop up and disappear quite frequently. In any case, it's not our fault: if the compiler crashes, it's a bug in the compiler. But there should be no need for Makefile hacking. If you find out what those people are recommending, we'd be interested in knowing. > Currently there is no mention of this problem on the Windows installation > web pages<http://doc.qt.nokia.com/4.7-snapshot/install-win.html>, indeed > MinGW is included in the instructions. Because we know of no problems.
