Hmm no timestamp? howeever 17.11.23
I had a similar issue with this Link Error:
Qt5Widgetsd.lib(Qt5Widgetsd.dll):-1: Fehler: LNK1112: Modul-Computertyp "x86" steht in Konflikt mit dem Zielcomputertyp "x64".
This message Pop up when I try to compile with the following setting
0_1511425158114_SettingMSVC2015_32bit.png
Even when I adjust it "more correct" to ...MSVC2015 32bit like this
0_1511425313879_SettingMSVC2015_32bit_MoreCorrectSetting.png
The message stay the same. I think it has to do with this line from (Projekte->Build-Umgebung)
C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.11.25503\bin\HostX64\x64;
So for me the solution was to use this Setting
0_1511425440418_SettingMSVC2015_64bit.png
I have a 64bit machine so it make sense. So my resume is do not set up 64Bit stuff inside of 32Bit?QtPlugins? And I am not able to use a 32Bit Debugger on my 64Bit machine.
OR expand the Microsoft Visual Studio\2017\Community\VC\Tools to HostX86\x86.
