Windows10, MinGW5.3, QT5.10 compiling failure on windows.h

theAdib

Hello I run into a serious regression problem.

I switched Laptop from Windows7 to Windows10. I have the 2 physically available.
Now my programs that have

#include "windows.h"

does not compile anymore and there are a lot of compiler messages.

You can reproduce when compiling the Qt example activeqt/webbrowser.
THis example also does #include "windows.h" and I can not compile anymore.
On my Windows 7 there is no problem.

Any hints? Do I have to set a "magic" define?

I also see that there is no CI toolset for the conbination Windows10&MINGW whereas WIndows7&MINGW Ci exists.
Any specific reson?

below is the compile output of the "build main.cpp" function only.

regards Adib.

@theAdib Did you try to delete the build folder, run qmake and rebuild?

theAdib

@jsulm Yes, I did.

Did someone can reproduce the compilererror on Windows10&MINGW?
testing the qt builtin example activeqt/webbrowser?

Adib.

Hi
I had no issue compiling

theAdib

@mrjj thanks for trying.

I have in parallel an Qt 5.6.3 and MinGW4.9 - the last version supporting WindowsXP.

I will remove everything and try again from scratch.

Adib.

@theAdib I confirm, when reinstalling Qt5.10.1&MINGW5.3 only then compiling the activeqt example works.

Thanks for helping out.

I will check how to put this ticket to "solved" somehow.

Regards, Adib.
