My second solution would be much more portable.

Hi,

Use the amd64 command prompt when building Qt.

I have checked the source code of the qmakeevaluator and the changes are present in version 5.9.1, still it does not recognize the platform. Even if I try to hardcode to the qmake evaluator the following:

vars[ProKey("QMAKE_TARGET.arch")] = ProString("x86");

It does not change a thing, still tries to link qmake to x64.

1:I saw on google that someone else had this error with gcc 4.8. Upgrading solved it. Not saying it will for you. But was the only errors i could find in your log.
2: Sorry I don't know how to solve this. People are compiling for the PI but I never got around to try one
so the details of getting it to work is also unknown to me.
Update:
I have a good eye to https://www.ics.com/blog/configuring-qt-creator-raspberry-pi but no board so didnt try yet.

@Pixtar You can use Visual Studio 2013 Community which is more or less same as Professional.

Thanks for the hint. :D

Hi,

Do you mean that if you build with MinGW-32 it's all working fine but not with MinGW-64 ?

Hi,

Yes that helped me, thanks a lot.
