<![CDATA[How to tell Qt which compiler to use]]>Hi, can someone please help me figure out how to tell Qt which compiler to use? I just installed latest Qt and tried to run an example, but it says "no compiler can produce code for Qt..." etc.

Under "Build and Run" it auto-detected MingGW (c:\minGW\bin\g++.exe) but apparently it wants a newer/different version? I tried reinstalling minGW (mysteriously,, it put it in C:\Program Files (x86)\mingw-w64\i686-5.2.0-posix-dwarf-rt_v4-rev0\mingw32\bin\g++.exe). Why it put it there ...and refer to posix, I have no idea. This doesn't sound right to me.

thank you!

In fact there is lots of 32bit software out there (like Firefox for example). In the online installer you can select Qt for MinGW and MinGW itself, just check the options the installer provides. Actually, the online installer suggests to install MinGW Qt by default, but check under Qt/Tools that the latest MinGW version is selected. The installer by default installs QtCreator as well. After installation QtCreator should auto-detect Qt and MinGW, if not configure a kit.

In windows 7 , It is a similar way Tools->options->build and run . Check for kits tab and you can point to MinGW

Is there something similar to this for Windows7?

But this installed Qt configured as MSVC. But I want Qt configured for mingGW.

Is there a version of Qt online configured for mingGW? Or is there a way I can tell Qt that I want to use mingGW (already installed on my machine)?

I'm running windows 7 Intel core i3 which I think is a 64-bit machine. Don't I need a 64-bit version of Qt?

If not just install MinGW 32bit version (in online installer you can select what you want to install).

I thought I had installed Qt on my machine a couple months ago and it worked fine. I don't remember building it but maybe I did. Anyway it works fine on my Raspberry Pi but I wish I could run it on my PC too.

at the moment no.
If you need 64bit version you have to build from sources

Qt 5.5.1 for Windows 32-bit (MinGW 4.9.2, 1.0 GB) (info)

Is there one for Windows 64-bit?

I was wondering what MSVC was :) OK, guess I''l try again from a new download...I didn't intend to use MSVC. I just want to use Qt/minGW.

Maybe I need to tell the Qt installer to ignore anything MSVC. There must be something lying around my computer making it think I use MSVC (I don't). I'll try uninstalling and then re-installed Qt unless you have a better suggestion.

thank you!!!

if you're using the MSVC version of Qt you need to install MS Visual Studio
