We love GNOME

We are building a true open source desktop environment!

GNOME Mobile?

It was announced at the Embedded Linux Conference in Santa Clara, California on April 19, 2007

Yes, we had GNOME Mobile

First release of GNOME MobileGNOME 2.24 is the first release of the GNOME Mobile development platform.

Linux-based mobile device platforms

Maemo, ACCESS Linux Platform,

LiMo reference platform, Ubuntu Mobile,

Moblin, Poky.

At the Mobile World Congress in February 2010, it was announced that the Moblin project would be merging with Maemo to create the MeeGo mobile software platform.

Nokia left behind us

No one talked about Mobile in GNOMEhttps://mail.gnome.org/archives/mobile-devel-list/

Unfortunately, there is no Success story with GNOME in Mobile.What's wrong with GNOME? Is GNOME is slow in mobile device?Were there any missing features for mobile?

Android vs. iOShttp://techland.time.com/2013/04/16/ios-vs-android/

Anyway, the mobile market is divided into Android and iOS. WebOS, Windows Mobile was disappeared. Windows phone & Blackberry are struggling to survive.

Why GNOME folks need to take a look at Tizen?

They say HTML5!!

But, we have a lot of GNOME applications

Running my favorite GNOME applications on Mobile?

On Android?

Only Linux KernelNo X-Window, No Cairo & Pango, ...

Looking into Tizen

Tizen Architecture

http://www.slideshare.net/badaindonesia/tizen-overview-and-architecture-seokjae-jeong-samsung-korea-linux-forum-2012

When we take a look at Tizen Architecture, you can find many GNOME & FreeDesktop components such as D-Bus,m glibc, Cairo, X11, Fontconfig, Freetype2, GStreamer, Geoclue, libSoup, Bluez, and SQLite

Tizen vs. Maemo

Glib, Cairo, Pango, Gstreamer, BlueZ, D-Bus, X-Window

OSP,EFL, RPM

HildonGtk+, Atk, Gdk-pixbuf, Debian

There a lot of common components between Tizen and Maemo.

X-Window, GStreamer, Glib, GObject, libSoup, BlueZ,

Tizen is a GNOME?

What is GNOME development?

GNOME developmentDevelop an application based on glib/gobject

The glib main loop is running inside Tizen apps.

Tizen?Tizen = MeeGo + LiMo

Standard based, Cross, Open Source platform

Resides in the Linux Foundation

Tizen 2.1

HTML5 and OSP(native) applications

Tizen Members

https://www.tizenassociation.org/members/

Intel and Samsung are leading the project.

Intel is no 1 Linux kernel contributor. Samsung is no 7 Linux kernel contributor. Two companies are very active to open source development

Therefore, Its okay to believe both companies. We continue to open Tizen more under Linxu foundation

Using Gerrit to access source code

Gerrit is a Web-based code review system

https://review.tizen.org/gerrit/

Create an SSH key with the Linux shell by specifying your full name and email address

Add the SSH Key to Gerrit

http://seoz.egloos.com/3895489Create an SSH key with the Linux shell by specifying your full name and email address

The SSH key is created in the ~/.ssh/id_rsa.pub file.

http://seoz.egloos.com/3895489

Paste the SSH public key into "Add SSH Public Key" text box.

Configure GITGit is a revision control and source code management tool

$ apt-get install git

Configure GIT

$ git config --global user.name "your name"

$ git config --global user.email "your email"

Git is a revision control and source code management tool that enables you to download and manage Tizen platform development source codes. You can also submit your modified source codes to Git.To enable the Tizen platform development, you must install Git:$ apt-get install git

Download Gtk+ and dependent libraries source codeTizen 2.0 includes

glib 2.32.3

pango 1.26.0
