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

mrhixxy

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

Sorry, error...

I'm in the same situation ...
after downloading the MingW 4.4 linked above i've to compile it or not ?

Is not avaialbe a mingw4.4-get-inst ?

I found this guide .
(italian but u will get the mean)
http://e-tweaks.it/blog/2010/03/installare-mingw-e-gcc-su-windows.html

There is an easier way ?
I'm not sure to be able to do it ...

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 :)

WOW finally something clear like the sun ...

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

Hopefully I'd saved Tdm MinGW 4.4 installation:

I start to develop successfully onto a windows environment .
Now i'm preparing the Mac environment .
Where can i find MinGw 4.4 for Mac Osx ?
Tkx

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

kenton

Mac programs .

qxoz

For mac Xcode should be enough.

JKSH

Then you don't want MinGW :) Just use Mac's compiler

kenton

Tkx qxoz & JKSK ,
i downloaded xcode today but my girlf. denied me to access her Mac :)

Anyway i'm at my place on Windows and i tried to give to a friend my release.exe file for a try ...
but the .exe ask for mingwm10.dll

How can i obtain a release indipendent from the environment ?
(linking with static libraries?)

JKSH

mingwm10.dll is found in your MinGW's \bin\ folder -- just copy it into your release.exe directory (you'll probably need a few other DLLs from there too)

Yes, linking to static libraries will let you do that, but you'll need to rebuild Qt statically

kenton

Good ...
and build Qt statically is something hard ?
Exist some guide ?
It's possible to download it already statically builded or not ?

Note: If it's the error messages about DLLs that are bothering you, just copy the DLLs into your .exe folder. You don't need to modify the environment.
