Why Qt libraries 4.8.4 for Windows (minGW 4.4, 317 MB) not include minwg 4.4?

-vexi- · wrote on 6 Dec 2012, 17:18

I remembering that the previous packages includes mingw. So why the latest packages not include it?
Where I can get mingw 4.4 because the mingw installer installed the latest mingw?
Or is the latest mingw supported in Qt 4.8.4? I quess not because it gives warning when installing qt

welcome to devnet

I guess last time you have installed Qt SDK. This includes qt creator, Qt libs and the compiler ( for windows MinGW). This time you have downloaded Qt libs only. Those are meant for upgrading to a new Qt lib version.

AFAIK the Qt SDK was at the very top of the download page in the past. To understanding the SDK has not been bundled with the newest version of Qt libs yet. The SDK is at the bottom of the page. I am not sure if the policy has changed.

As far as I know because there were too many complaints about it.

One group complained that they already had mingw installed and did not want to download it again. A smaller group complained that we included the wrong flavor of mingw (which they did not want to download either since they had the right flavor already installed).

@Tobias: Would it be viable to provide it as an OPTIONAL download in the SDK, even if the user selects the MinGW variant of the Qt libraries? Maybe have a message on the next screen, telling the user that they can either get MinGW from the SDK (which would be the Tier 1 supported version), or from their preferred provider?

JKSH: I hope there will be something a bit easier with Qt5. That is going to be a SDK again and from what I read on the mailing lists it should (eventually, maybe not included at first) be possible to install Qt4 using it.

@vexi : Is you get to do the installation?

Does this mean that for us who can't or don't want to use the VC++ compiler, we have to compile Qt from source using the latest MingW compiler?

I've searched high and low for somewhere to download MingW 4.4 without success.

If this is so, the MingW packages you have up seem kind of pointless.

Why is the old Qt SDK containing everything not still made available in the interim until a new fully integrated SDK is available?

Is it not possible for MingW 4.4 to be made available as a separate download until such a time?

Nice thanks. I was almost tempted to try my hand at compiling from source. The links on the pages where the instructions should be don't work:

"http://qt-project.org/wiki/Get_The_Source#c5655294df78acbcb9ac6fdb87cbb620":http://qt-project.org/wiki/Get_The_Source#c5655294df78acbcb9ac6fdb87cbb620

Download MinGW 4.4, extract it into any folder (e.g. C:\MinGW)

Download "Qt libraries 4.8.4 for Windows (minGW 4.4, 317 MB)" from http://qt-project.org/downloads , run the installer

Download "Qt Creator 2.6.1 for Windows (52 MB)" from http://qt-project.org/downloads , run the installer

Open Qt Creator, configure it by going to:

Tools -> Options -> Build & Run -> Qt Versions -> Add

Tools -> Options -> Build & Run -> Compilers -> Add

Tools -> Options -> Build & Run -> Kits -> Add

Start writing programs :)

The above instructions were for Qt 4.8.4 and MinGW. If you want the latest Qt 5.0.0 (with Visual C++ 2010, not MinGW), do this:

Download and install Windows SDK 7.1 (32-bit) from http://download.microsoft.com/download/F/1/0/F10113F5-B750-4969-A255-274341AC6BCE/GRMSDK_EN_DVD.iso (it's ~570 MB)

Restart your computer

Download and install Qt libraries 5.0.0 for Windows (VS 2010 406 MB) (This already includes Qt Creator 2.6.1)

Start writing programs

My little experience by now was with wxwidgets only .

On Qt , programs source code is different if compiler is different ?
(MingW vs VC)

Or it's the same until i remain on the Qt / C++ statement ?
(i don't know if this question have sense...)

But, if you compile your program with MinGW, your Qt library (or your Qt DLLs) must also be compiled using MinGW. That's why they have different library downloads for different compilers.

Hi, i followed the MinGW way and all work fine !!

I specify here the paths setup because i lost a bit of time for it :

Tools -> Options -> Build & Run -> Compilers -> Add -> C:\MinGW\bin\gcc.exe
Tools -> Options -> Build & Run -> Qt Versions -> Add -> C:\Qt\4.8.4\bin\qmake.exe
Tools -> Options -> Build & Run -> Kits -> Add -> autodetect

MinGW is for creating Windows programs. Do you want to cross-compile for Windows, or create Mac programs?
