I just want to develop for n900 with Qt4.6 in Windows, and I am not familiar with Linux.

So please tell me what I should do for the development environment.

And what should I do if my app may need maemo5 APIs. I just installed Qt4.6(including creator, designer).

Plz, thx.

You installed Nokia Qt SDK Beta?

There is a readme in NokiaQtSDK/Maemo.

Indeed.

Install the new Nokia QT SDK, it works like a charm for me.
It has a fair IDE, and you can write code and launch your app on the N900 with one click.

Does "Nokia QT SDK" include Maemo5 APIs?

Yes.

Too short message.

Cool, thx Diph, thx all bro.

Of course. It contains MADDE. You can read more about that in the wiki.

Once you launch the application on the n900, is it possible to run it without the usb connection? how do i make a .deb inside windows?

Apps launched from QT Creator are stored in /root folder on n900. You can copy them and run from xterminal just as any other app without the need of usb connection (or wifi). To make a deb on windows you have to open Madde console and create a new project skeleton with
than go in the created directory from explorer and copy all source codes done in qt creator into the src subfolder. Copy all source and header files there. The QT designer uis must go in the uis subfolder, Changelogs and descriptions are in the files in debian subfolder. In data subfolder you put the icon in png format and edit the .desktop file. Than you have to edit the qtprog.pro file in the main project folder, adding all sources headers and forms. When you're done from MADDE console change directory to your project folder and run and . If there is no error in the compiler you can create the package by calling
. Watch out some classes and references in qt creator are different from the ones in madde, code running in the first may be edited to run in the second.

Gioni88, good explanation, except for this part:

If you use MADDE with Qt Creator, it will place the executable files into the /home/developer directory. (or, if use use it with another user account and not developer, it will put them int that account's folder, I think)

You can run them from there from the terminal:

If you run it from a root terminal:

where "myapp" is the name of your app's executable (usually without extension)
