Since Tizen adopted "open governance model", a free and libre open source GNU/Linux distribution known as "Tizen:Common" came to light. Now anyone is able to install it on widely available machines (PC, NUC, VM etc) and use the rolling release distro for any purpose, let's go one step foreward and build software for it and make a basic bug fix. This kick-start session aims to go directly to the pratical way to use it or/and contribute to Tizen. Tizen development tools (git, gbs, gerrit, jira...) will be presented live in real action, to give a short overview on how the project is progressing on a daily basis. Curious developers unfamiliar with platform development, can expect to get the entry's keys and learn by example on how to work on tizen platform and eventually share their wildest dreams.

9. Tizen sources

10. 10
Join Tizen
• 1. Register your account at :
– https://www.tizen.org/user/register
• 2. Generate a ssh key and upload public key
– ssh-keygen && cat ~/.ssh/*.pub
– https://review.tizen.org/gerrit/#/settings/ssh-keys

11. 11
Fetch tizen's sources with git
● http://source.tizen.org ( Same as Gerrit : projects / List )
● Edit ~/.ssh/config :
Host review.tizen.org
Hostname review.tizen.org
IdentityFile ~/.ssh/id_rsa
Port 29418
User $USER # <=== EDIT WITH YOURS
● Clone one project (ie: platform/core/api/connection)
git clone review.tizen.org:/$project
cd $project
git branch -a
git checkout tizen
ls packaging/*.spec

12. 12
Install tools
● On a GNU/Linux System
– Example for Ubuntu
cat /etc/apt/sources.list.d/tizen.list
deb http://download.tizen.org/tools/latest-release/Ubuntu_13.04 /
sudo apt-get install gbs
sudo apt-get install mic lthor bmap-tools meld # (optional)
– Others are supported Debian/Ubuntu, OpenSuse, Fedora, ...
● Reference:
https://source.tizen.org/documentation/developer-guide/envir
onment-setup/

13. 13
Building sources
• Configure repos : ~/gbs.conf
– Use mine from :
https://gitorious.org/tizen/tizen-helper/raw/master:config/gbs.conf
– Add new profiles and associated repos if needed
– We prefer common snapshot x86_64 wayland repos
• Build from sources (git) to binaries (rpm)
gbs build
-P "profile.tizen_common_x86_64"
--arch x86_64
find ~/tmp-GBS-tizen_common_x86_64/local/repos/ -iname "*.rpm"

14. 14
Deploy & Test
• Copy RPM files to target
– scp *.rpm root@$targethost:/tmp
– sudo zypper in /tmp/*.rpm
• Tip : better setup your own repo from your host
– Setup local httpd server (apache's mod_user_dir)
url=http://$host/~$user/.../tmp-GBS-tizen_common_x86_64//tizen/x86_64/
zypper ar $host $user # Add your repository
zypper ref -r $user # Refresh it
zypper up -r $user # Upgrade system from it
zypper in -r $user $package # Or install single package (+deps)
