Randa: KDE Games for Windows

As you may have already heard or read, the kde games stack has recently migrated to the git infrastructure. The new KDE Windows source packages are finally available now by using emerge. The changes will be hopefully available for end users later at the 4.9 release.

I have just skimmed through the build for all the packages by using "emerge kdegames" and there were no build issues which is cool. I do not have time for now to test all the games during the runtime, but I briefly fired up KBreakOut before going to sleep. :-)

Randa: KDE Frameworks build experiment on Harmattan

We had two great (plus one about the generic QML topic) sessions today I attended, here at the KDE Edu Sprint.

The topics were KDE Edu on Windows and then on Plasma Active. I will try to blog about those sessions later as I found them really interesting and noteworthy.

We had an idea about coordinating and discussing the effort for the Qt5/KF experiment. The session was not yet held, but let me blog a bit now about the Qt5/KF efforts anyway. :-)

As you may already know, I have a genuine interest to bring Qt and KDE to mobile platforms in general. ;-) Due to the lack of accces to the raspberry pi, playboook and so forth, I am only able to experiment with KDE Framework on my N9. I have just made the extra-cmake-modules, cmake 2.8.9, the phonon version 4.6.0 available for this platform.

Here are the step how you can build the frameworks branch of kdelibs for Harmattan:

1) Add the following repositories (Nokia and Community) to your sources.list files:

deb http://harmattan-dev.nokia.com/ harmattan/sdk free non-free
deb http://repo.pub.meego.com/home:/rzr:/harmattan/MeeGo_1.2_Harmattan_Maemo.org_MeeGo_1.2_Harmattan_standard/ ./

2) apt-get update

3) fakeroot apt-get install qt5-* (the qt5 dependencies you need)

4) fakeroot apt-get install cmake extra-cmake-modules libphonon-dev

5) git clone -b frameworks http://anongit.kde.org/kdelibs

6) export PATH=/opt/qt5/bin:$PATH

7) mkdir kdelibs/build && cd kdelibs/build && cmake -DCMAKE_SYSTEM_PREFIX_PATH=/usr/phonon ../

The CMAKE_SYSTEM_PREFIX_PATH needs to be used unfortunately as we are unable to override system packages on Harmattan. Thereby, the phonon package and files cannot be overriden by the KDE phonon packages and files we need for frameworks. Hence, the prefix install "/usr/phonon" is used for now.

It is not as difficult as it seems, albeit not the prettiest either admittedly. :-)

Yet, I am happy with this achievement as it is a great milestone for the frameworks branch to be tested from non-desktop and ARM point of view as well. :-)

QtQuick 2 is coming to Harmattan

I have made all the basic packaging for Harmattan right after the Qt beta 1 release. Now you can install the following packages from the community repository: qt-3d, qt5-base, qt5-declarative, qt5-jsbackend, qt5-location, qt5-multimedia, qt5-script, qt5-sensors, qt5-xmlpatterns, and qt5-components.

As you can see, there is also a qt5-components package available. Last night I put some effort into porting the qtquick2 branch of the qt-components project to Qt5. Here you can find the steps to start the work on a Qt5/QtQuick2 application for Harmattan:

* echo 'deb http://harmattan-dev.nokia.com/ harmattan/sdk free non-free' >> /etc/apt/sources.list.d/nicks.list
* echo 'deb http://repo.pub.meego.com/home:/rzr:/harmattan/MeeGo_1.2_Harmattan_Maemo.org_MeeGo_1.2_Harmattan_standard/ ./' >> /etc/apt/sources.list.d/nicks.list
* apt-get update
* fakeroot apt-get install qt5-components

The QtQuick2 port to Qt5 has not yet been thoroughly tested, so runtime issues may be expected. If you would like to contribute, please grab the code from here:
git clone -b qtquick2 git://gitorious.org/+harmattan/qt-components/harmattan-qt-components.git

Contributions still warmly welcome! Thank you for your attention.

Qt5 Beta 1 is coming to Harmattan

First of all, do not forget we still need some support for our Randa sprint.





I have just re-packaged my previous Qt5 snapshot version for the Qt5 base module last night. Having gotten the news about the beta 1 release yesterday, I have felt the urge to do so. :-) For installation, you need to do the following in your development environment (or on your phone):

* echo 'deb http://repo.pub.meego.com/home:/rzr:/harmattan/MeeGo_1.2_Harmattan_Maemo.org_MeeGo_1.2_Harmattan_standard/ ./' >>/etc/apt/sources.list.d/nicks.list

* apt-get update

* fakeroot apt-get install qt5-base

Done. Unfortunately, there are some ongoing issues for the Community OBS which currently block me to get the Qt5 jsbackend and declarative modules publicly built and distributed. Just one important of those:
https://bugs.meego.com/show_bug.cgi?id=25710

Hope for the declarative module to be available soon, and then we can finish the QtQuick2 branch port of the qt-components project. This means the new plugin and native event filter API usages and so forth.

As you can see, there is still a way to go, but the base is already there. :-)

Contributions warmly welcome!

Support the 2012 KDE Randa Meetings

If you are in a position where you are able to help us to make this a success story, please consider so. :-)

Here you can find the official announcement:

As a participant last year to the Randa meetings, I can also assure you without any hesitation: it is an awesome and very beneficial event from many point of views.

KDE Edu


I will be participating in the KDE Edu sprint, and it would be gratifying to keep the excellent free software stack for education going on nicely. It has been a solid and well-proven stack for many years now, but we always face new challanges with the rapidly changing world and technologies around. Here you can find our official website:

http://edu.kde.org/

We have been recently putting a lot of effort into making the educational stack more accessible on mobile devices (tablets and phones). Needless to say, we also have interesting challanges on desktop as well on various platforms (Windows, Linux, and Mac).

Free and accessible software is very important for us in Education. If you like having this option for teachers, kids, students, and pupils: I can only encourage you again to kindly consider your support, even if it is just a penny. =)

Here you can find the presentation slides and my talk with Aleix at the annual aKademy summit this year for further information:

Getting back to FOSS contributions

Hi,

Unfortunately, I have been busy recently with a couple of serious real life issues. Yeah, our life is not always an easy-peasy cakewalk; we sometimes think it is getting very grim. I was traveling back to Hungary about three weeks ago when I got the news my dear father had deceased after a stroke. It was two years ago, when I last saw him, but I still clearly recall his activities. What a great person, he will be extremely missed.

It was not an easy situation, Christmas and New Year's Eve for us, especially for my mother who has spent 46 years with my father in this material life. I have tried to take care of my mother mentally and financially as much as possible. As for me, it was much simpler to accept the fact than I thought even though I loved him a lot. I prayed a lot for his soul during this period, especially during the funeral to reach the most appropriate position ever. I have a good poem for the situation that I would like to share (probably a good candidate for my pall when I reach my "end"):

For the soul there is neither birth nor death at any time. He has not come into being, does not come into being, and will not come into being. He is unborn, eternal, ever-existing and primeval. He is not slain when the body is slain.

- Bhaktivedanta VedaBase: Bhagavad-gita As It Is 2.20

Unfortunately it took an effect on my leisure time FOSS contribution and I had to withdraw my mentorship help of the Google Code-In session. Thanks to Lydia for helping me with that. I also had to withdraw my help from the KDE and Qt5 contributions that I previously discussed with David Faure. I am really sorry for those, again.

The good news is that, I am now entirely back to Helsinki and can concentrate on amending the time spilling regarding these activities. I have also been organizing a Qt MeetUp [1] in Helsinki next week. It is also a sort of KDE 4.8. release party. Hope to see some of you there.

I would like to wish a happy new year for you with a lot of FOSS acitivities. :)

KDE Mobile and Gluon reports

Hey hey :)

As you may have already known: I have taken a subtle hint at the end of my previous blog post about the "KDE Mobile on Harmattan sprint". I would now like to show what has been happening. I will be much shorter this time than usual. =)


KDE Mobile on Harmattan sprint

The KDE Harmattan sprint has really been an amazing event for me in my life. Very impressive to see people caring about KDE on handset platforms, like this shiny N9 and Harmattan. You can read our wikipage about the issues we realized in advance and discussed thoroughly at the sprint:
http://community.kde.org/KDE_Mobile/Harmattan

Social event with the KDE e.V. 2011 sprint participants

You can find a more detailed story about the sprint on the following page:

Gluon Player for Harmattan

I have also worked on Gluon a bit at the sprint, and also later as a post-sprint
activity in my leisure time. I am really thankful for the help and feedback I
was able to get from the people about the sprint, but as well as about the
Harmattan Gluon Player. Here you can find some screenshots of the current state:

 

Game List Page

Game Details Page

Note, there are no proper margins yet on the pages. That is because, for the time being, I decided not to hack around. The relevant qt component version will be having the facility "UiConstants.DefaultMargin". This is not available yet on the PR 1.1 firmwares, but will probably come along with the PR 1.2 update. Disclaimer: we do not really have mature games yet for N9, thus this follow up is only about the Gluon Player application, not the games themselves.

Future plans:

I would really like to say again. please stay tunned. The story is definitely not over! Having had the KDE Harmattan sprint in this success: I started to deal with creating an Android target in scratchbox. since Qt on Android has been coming along very nicely, I would also like to start the researches about the KDE Android development. I will be trying to organize a KDE Android sprint as soon as the technology of ours make it possible. Thank you for reading, really! ;)
