Several errors after Qt update

[UnitScan]

I update my Qt version from 5.70 to the latest, .5.12.1, With the old version, everything works fine: after update, I try to launch my app, and this is the result:

There is something new that I need to know?

Thank you in advance

@UnitScan Did you try a complete rebuild (delete build folder, run qmake and build)?

mmh, can you show us the kit's & compiler tab of your configuration/settings of QtCreator.

Seems as if there's something not ok.

@UnitScan
well yes,
you have mingw compiler assigned to MSVC precompiled Qt-Libs. Unsurprisingly this does not work.

You need msvc compiler for that precompiled QT-Lib or you need to download the mingw-libs.

@J.Hilk ok, where I can find the MinGW libs?

[J.Hilk]

@UnitScan
how did you install Qt to begin with ?

If you used the online installer, you can use that tool to add missing features:

If you used the offline installer than you'll have to deinstall Qt completely first, as the offlineinstaller does not allow for later changes.

@J.Hilk My Initially I did not install it because my system is 32bit

Yes, that is currently an issue, there are talks of adding mingw32 precompiled libs to the downloader, but that's still up for discussion.

You have 3 Options than,

• switching back to 5.11.3, IIRC those have precompiled 32 bit libs for mingw
• installing MSVC compiler(for legal reasons you have to get them manually from Microsoft)
• compiling 5.12.1 yourself

Solved, thanks @J-Hilk
