BUT… there are people who prefer “Livin’ on the Edge“. If you are one of those and already want/need to develop with Qt 4.7 (not released yet!) for Maemo 5, using MADDE to build your applications / packages, here is an update to the procedure first published by the troll Harald Fernengel (AKA harryF). Although the title says “on MacOS X”, the steps also work on Linux.

Step-by-step:

• Install MADDE. Download it here.
• If you are not using a Debian based distro, you need to install the “Tools for Debian Packages” package of your distribution (e.g. “deb” on openSUSE, sys-apps/debianutils on Gentoo).
• Download the script fetch-qt4.7.0~git20100520-0maemo1.sh fetch-qt4.7.0~git20100614-0maemo1.sh . This script downloads the libqt4-experimental packages from repository.maemo.org and installs then in your MADDE – Before you run the script, remember to adjust the MADDE_PATH variable according to the path you installed MADDE.
• Download qt4-maemo5-qt4.7.0~git20100520-0maemo1.tar.gz qt4-maemo5-qt4.7.0~git20100614-0maemo1.tar.gz. It contains the Qt tools compiled for the correspondent version, configured for cross compiling. Extract to /opt/qt4-maemo5.
• Check if mad is in your PATH.

To build an application using your fresh environment, run /opt/qt4-maemo5/bin/qmake && make .

If you succeeded in the setup process, this should result in a armel binary ready to run on N900. To generate a deb package, you can use the tools offered by MADDE to build a skeleton of debian package and so on.

To run your application on N900, install libqt4-experimental-* packages. If QtQuick (QML) is part of your plans, qmlviewer  is in the package qt4-experimental-declarative-qmlviewer .

UPDATE (2010-06-15): For newer (or older) versions, check http://anselmolsm.org/public/qt/madde-qt47/

In the first season, the focus was S60 devices. After the holidays, the new season is about Maemo. =)

Qt Mobile Demos are in Maemo 5 extras-devel, so now it’s easier to check them in a N900 near you. First, you need to enable the extras-devel repository/catalogue and the demos should appear if you search for “qtmobile”.

The packages are:

hyperui -> qtmobiledemo-hyperui

mybudget -> qtmobiledemo-mybudget

shoplist -> qtmobiledemo-shoplist

weather -> qtmobiledemo-weather

Future? Well, soon QAbstractKineticScroller will replace our kinetic list implementation. (Read the comments).

And yes, we have a list of known issues to solve in our free time…

The code still in the same place, http://qt.gitorious.org/qt-labs/mobile-demos

That’s all for today.

PS: Thanks to Etrunko, who helped a lot with packaging stuff =)

To celebrate the new version of Qt, the first with the S60 port, we thought it would be nice if people could also check those demos on desktop platforms. You know, Qt is everywhere =)

As the release was yesterday, probably there are people without Qt 4.6 installed in their desktops yet… so we prepared binaries with Qt 4.6.0 statically linked =)

Linux version

Windows version

Mac version (Unfortunately I don’t have a Mac available here right now. Contributions are welcome =)

It’s worth a mention. The source code for all platforms is basically the same, the only difference are due to different screen sizes, different connections methods.  This code is still available in the same place: http://gitorious.org/qt-labs/mobile-demos

And again, owners of  either S60 devices or N900 find packages at: http://qtlabs.openbossa.org/mobile-demos .

TODO: Fix the bug in the weather demo when there’s no connection…

PS1: As an extra activity, support for keypads is work in progress (I have a N85 =P )

PS2:  Now that Qt 4.6.0 is out, it’s a good moment to make it work again …

PS3: Hello planet KDE! \o/

About 3900 people are already registered for the event and personally I expect a great opportunity to meet people, some of them I only know from IRC or mailing lists, maybe new partners for Qt Labs Americas in other countries of Latin America =) and also a chance  to learn new things.

Learn and teach a little! =) If you take a look in the conference’s program you will see that some colleages are going to speak there. Artur de Souza (MoRpHeuz) will present an updated version of his talk about Plasma Netbook (including a cool demonstration =). In Caio Marcelo‘s and Eduardo Fleury’s talk, the attendants will see what are the new possibilities in graphical interfaces development with Qt (and for KDE). Another openBossa speaker is Kenneth Christiansen with a presentation about QtWebkit.

People interested in learn how to develop with Qt and KDE will have a great opportunity because there are 2 courses by the guys of Live Blue. In the last day (Saturday October,24th) Jesus Sanchez-Palencia and me are going to head a course on the new Qt 4.6 APIs .

Besides the mentioned ones, Ana Cecília (annieC) will talk about an usability study on FOSS.

So, if you are going to Foz do Iguaçú, see you there! =) And if you won’t go, stay tuned for the news.

To ease this process, I wrote a small script that does almost the same described in Lizardo’s post, with some new pseudo features. It needs some improvements, the known ones are marked with #XXX – contributions are welcome!

It consists in 2 files, the script and a config file where the user can customize the directories where things will be installed, the directory of the downloaded files, the version of S60 that will be used. Initially it’s ready for S60 3rd edition FP2 and S60 5th edition (Check here the version of your target device), etc.

Running the script, the first step shows the URLs to files you have to download, but need login or other kind of interaction with the website. The script is a nice guy, when it’s possible “he” asks if you allow him to open those URLs in your default browser =)

The script then downloads other files that are direct accessible and the installation begins. If everything goes right, in the end your environment will be ready for Qt-S60 development.

Wanna try? Download a it here or git clone it:

git clone git://littlechina.org/anselmo/setupQtS60env

That’s it =)

ToDo:

• Simplify updates of Qt-S60 in a environment already in use.
• Solve the #XXX in the script
• Probably there are other things that I don’t remember now =)
• UPDATE: 2009-10-17: There are some issues in qmake when using DEPLOYMENT
• UPDATE2: 2009-10-19: The old daily builds aren’t available anymore, a message there says that they “back tonight hopefully”
• UPDATE3: 2009-10-20: Builds are back =)
• UPDATE4: 2009-11-01: The gnupoc patch for Qt-S60 needs to be uptaded =/ .
• Hopefully it’s going to save us =) http://labs.trolltech.com/blogs/2009/10/28/a-new-symbian-toolchain-for-linux/
