Hi and welcome to devnet,

What version of MinGW are you using ?

it appears msvc 2015 is my only option for a compiler on windows 10?

No. It is just the only option that is officially supported by The Qt Company. You can still use MinGW.

The following works for me on Windows 10 Pro 64-bit:

• Install Visual Studio 2015 Community Edition, including C++ support and the Windows SDKs for the desired targets
• Use Qt online installer to install...

1. Qt 5.6 prebuilt components for MinGW 4.9.2 32 bit
2. Qt 5.6 prebuilt components for msvc2015 64 bit
3. Desired Qt modules: Qt Canvas 3D, Qt Location, etc
4. Qt Creator 3.6.1
5. MinGW-builds 4.9.2 32 bit toolchain

This setup gives me two kits in Qt Creator, msvc and MinGW.

Hi @Wieland ,

Could you please elaborate on this (not related directly to the first question).
I tried to install several version of "Visual Studio 15" on my Windows 10 PC. The latest version I tried to use it "Visual Studio Community 2015 32-bit (French) - DreamSpark". Which version of MSVC should I download ? Is there a 64-bit version as well ?

The following works for me on Windows 10 Pro 64-bit:

• Install Visual Studio 2015 Community Edition, including C++ support and the Windows SDKs for the desired targets

2. Qt 5.6 prebuilt components for msvc2015 64 bit

I do not want to use MinGW any more. I hope I will not have problems with the toolchain. Any experience with Windows10 Qt 5.6 and MSVC 15 ?

@metch Hi, and welcome! I downloaded Visual Studio 2015 Community from https://www.visualstudio.com/. If you see the website in French then the online installer you'll get will also be in French. If you prefer a different language then just scroll down on the website and switch to that other language before you download the online installer. Like I already said my host is 64 bit and the online installer also gave me 64 bit version of Visual Studio. I just installed Windows 10 on that machine so there were no older Visual Studio components or Windows SDKs present.

@SGaist Not sure how to tell what version of MinGW I am running. I am running QT 4.4.3.

@Wieland Hi. So I guess I'm still not quite sure what to do to resolve my issue, given I'm on QT 4.4.3. is the G++ a part of MinGW? That's the only issue I'm having at the moment. I'm trying to update to the newest version of MinGW hoping that will solve my issue. Any other thoughts given my particular setup?

@Scott-Krise
Hi yes g++ is part of the mingw setup.
It seems that it has issue on win10.

4.4.3 is kinda old. do you need to stay on this version ? (really need)

If you update the mingw installation, i think u might need to compile a version of Qt with that newer mingw version as else there might be other issues. Not 100% sure there will but good to keep in note.

I use mingw and qt 5.5 and 5.6 with windows 10 with no issues.

Also: i assume u did try to reinstall just to rule out that is not just yet another upgrade bug.

Type g++ --version in a console.

BTW: AFAIK you cannot simply replace your old MinGW with a newer one. If you do so you'll also have to rebuild your Qt libraries with the new toolchain. I think that's because otherwise you'll break binary compatibility.

[Scott Krise]

@mrjj Ya, I hear you. I know its an older version, but the decision isn't mine at the moment. Ill see if I can move in that direction.

If you can't go with Qt 5, try at least Qt 4.8.7
