I got following error message when building Qt quick application

This seems to happen also with helloworld app. C++ qui app compiles normally. My Qt version is 4.71 and tried new Creator 2.1 beta2. I also tried MinGW 4.5 with no effect. OS is windows 7 64-bit. Same app compiles perfectly on Mac.

Thanks

I have the same problem, I have reported it.

Seems that Creator 2.1 RC fixed problem for me.
