Hi,
as a start, download the SDK (I suggest Qt SDK 1.1 Beta) from "this site":http://qt.nokia.com/downloads . Depending on the platform, choose the installer (for windows I use online installer, as I then only get what I really need, e.g. no meamo, meego, symbian).
Then start reading QtCreator docs, it's part of the SDK, or read it "online":http://doc.qt.nokia.com/qtcreator-2.1/index.html
-
For "getting started":http://doc.qt.nokia.com/4.7/how-to-learn-qt.html, the Qt documentation contains some fine "tutorials":http://doc.qt.nokia.com/4.7/tutorials.html as well.

thatz really great...what a quick response...I have just started downloading those files you suggested..thanks a million

Hello Gerolf/Andre,
Thomas again !!
I have installed QT SDK 1.1 Beta yesterday without any problems and tried executing examples to understand the code flow and successfully executed on my Windows 7 professional desktop. I am really impressed with the simple coding style QT followed.
Now my question is how can I run the same executable( say for example "Extension example from Dialogs") on Linux OS ?
could you please explain me step by step now ?
Thanks in advance.

You install the SDK for linux and build the executables there. Same procedure....
Or you get a creoss compile environment, install it on windows, build for linux and copy, but I think, native building will be easier.
-
where can i get a cross compiler for QT and how can i make it for Linux? please help !!
-
I never cross compiled from windows to linux.
Did you ask google? -
If the customer is aiming at application which can be installed and executed on both Windows and Linux, how would we do that using our QT ?
can you please guide me in a detailed manner Gerolf ??
-
I would build natively on windows and natively on linux. Especially as Linux != Linux (distribution).
Use a seperate machine, virtual machines whatever and build on both. -
lemme know if my understandings are correct…
- develop the application on one OS using QT (windows or Linux).
- Get the .exe file in Release mode on native OS (say Windows).
- Run the same code on the other desired OS (say Linux which can be the other OS of my Dual OS system and has the same SDK) and get the .exe in release mode.
- make an installable setup (write a script which can pick up the required ‘files and .exe’ by recognizing the OS during installation) which is installed and executed according to the customer specifications.
- make the customer satisfied :-)
…..i am right Gerolf ??
-
Yep, thats the way to go.
If you use a version control system or some shared drives, you could also switch during developement (which never is bad for testing if everything really works). -
million thanks Gerolf..please be with me while learning the coding..

Hello Gerolf,
got a problem again..
have downloaded the Qt SDK 1.1 Beta for Linux. Tried installing it and ended up with this error..
./Qt_SDK_Lin64_offline_v1_1_beta_en.run: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by ./Qt_SDK_Lin64_offline_v1_1_beta_en.run) :-((
could you please help me in sorting this ?!
-
I don't use Linux, I always use windows, sorry.
-
try to install libstdc++.
Question: which distro do you use? And do you have g++ installed already? -
thanks for the response man..i am totally new to Linux..could you please lemme know how to fetch those info you asked ??
-
If you're on linux, you should already have that lib I'd say.
-
I have installed CentOS 5.5 yesterday and tried to install Qt..could you please gimme those commands to check if that lib is existing and its verson ??
-
For linux help, you're on the wrong channel. Sorry. This is not Qt related anymore.
