Incompatible compilers

viniltc

Hi,

I am trying to build a 32-bit application. I have configured the kit Qt 5.12.0 MSVC2017 32bit.

C++ compiler : Microsoft Visual C++ Compiler 14.0(x86)

However there is a warning which says The compiler "Microsoft Visual C++ Compiler 14.0(x86)" (x86-windows-msvc2015-pe-32bit) may not produce code compatible with Qt Version "Qt 5.12.0 MSVC2017 32bit" (x86-windows-msvc2017-pe-32bit) "

Interestingly, I cant't see Qt 5.12.0 MSVC2015 32bit in my list of kits available, and I don't have compatible compilers for Qt 5.12.0 MSVC2017 32bit as well !!

Any suggestions?

Since MSVC 2015 and 2017 are not compatible (as you already found out) you only have two options

use a MSVC2017 compiler
compile Qt with MSVC2015 by yourself

I would go with the latter since MSVC2015 is way too old.

@Christian-Ehrlicher Hi, If I compile wih MSVC2015. I get an error :

:-1: error: LNK1158: cannot run 'rc.exe'

I remember it is something related to some settings within the systems environment. Not sure what exactly it is.

What do you compile?
MSVC2015 is more then 8 years old - use a recent compiler.

@Christian-Ehrlicher Hi, I've a basic question. Im not sure how to configure a new compiler. Do I need to install Visual Studio 2017 for that?

When you want to use MSVC2017 you should install it, yes.

@Christian-Ehrlicher. I am using Qt Creator as IDE. I am a bit confused what to install for MSVC 2015 32-bit compilers. Do I need to install the entire Visual Studio 2017 or juts Build tools for Visual studio 2017?
