How to install Qt ???

Hi guys. My name is Dany and I'm new on this forum.
I would like to learn programing with Qt, but I don't know how to install it.
I tried 3 versions but no success :( I have these 3 versions :
- Trolltech Qt Commercial 4.4.0 (from demonoid)
- Trolltech Qt Commercial 4.3.1 (from demonoid)
- And this one downloaded from official site
qt-win-opensource-src-4.4.1.zip
qt-win-opensource-4.4.1-mingw.exe

When I installed Commercial 4.4.0 everything looked OK, but when I tried to compile
Hello.cpp I enter command qmake -project (that was OK), then qmake hello.pro (that was OK too), but when I entered command make then:
'make' is not recognized as an internal or external command operable program or batch file.

The only compiler I have on my computer is Dev-c++.
Can someone pleas tell me how to install Qt, or point me to some good step by step tutorial on how to install Qt.

Hi
In my opinion you have installed Qt correctly, the problem is that make utility is not on your system. I am new to this also, but I have seen that error before, and it looks like make is not on your system.
Without QT, what do you use to compile your 'other' programs? do you use make?
Did you path the location of your make utility? compiler tools..etc?

This link has almost everything you need http://doc.trolltech.com/4.4/index.html
I am using 4.4 version, but you can find the other versions in that same area. Or just change the url to 4.0, 3.3..etc.

Assuming you have installed Dev-Cpp in C:\Dev-Cpp
you should mention that path when installing qt-win-opensource-4.4.1-mingw.exe, when it asks for mingw.

After you install with the path of Dev-cpp, you should be able to run the qt apps with the console that is there in "Start->All Programs->Qt by Trolltech->Qt{version} command prompt"

But if you want to compile from cmd, and run apps with double clicks,
Just create environment variables as shown in Qt{version} command prompt
Assuming you know how to add env variables in windows, just
Add QTDIR & QMAKESEC to environment variables
and
append QTDIR/bin to PATH

restart the computer, everything should work fine.
You can ask if you want more detailed explanation. I might be slow in replying, though.

There You can find everything:

Good luck ;)

Guys thank you soooo much. Now I did it successfully. :D :D :D

I installed it on Backtrack3. Working 100%.
This is how I did it :

Code:

---

cd /usr/local
wget ftp://ftp.trolltech.no/qt/source/qt-x11-opensource-src-4.4.3.tar.gz
tar -zxvf qt-x11-opensource-src-4.4.3.tar.gz
cd qt-x11-opensource-src-4.4.3
./configure -qt-gif -stl -xinerama -sm -no-exceptions
make install

Thank you guys for helping me.
