==== Setting up your build environment  ====


If you intend to create or modify any software, you need a working build environment. The build environment consists of a number of command line tools:

  * gbs: Git Build System - use this for building software components
  * mic: MeeGo Image Creator - use this for building system images
  * osc: openSUSE buildsystem commander - use this for remote builds

You can find these tools from [[http://download.tizen.org/tools|download.tizen.org]]. Use the instructions below to install them to your development system. You can copy-paste the commands below. Note that the //osc// tool is installed automatically with //gbs//.

For **Ubuntu 12.04 LTS**:

  
  $ sudo apt-add-repository 'deb http://download.tizen.org/tools/latest-release/Ubuntu_12.04/ /'
  # Enter your password for sudo
  $ sudo apt-get update
  $ sudo apt-get install gbs
  $ sudo apt-get install mic
  


==== Building an example package  ====



=== Getting the source  ===


First step in building is to get the source code and to import it using gbs.

  
  $ mkdir dialog
  $ cd dialog
  $ wget http://download.tizen.org/snapshots/trunk/ivi/latest/repos/ivi/source/dialog-1.1-9.5.src.rpm
  $ gbs import dialog-1.1-9.5.src.rpm
  


=== Configuration of gbs  ===


Importing the acpid package with gbs creates a gbs configuration file. By default, gbs configuration file point to a different repository than what is used in this example. So, the mandatory step is setting the correct url.

Start you favourite editor, vi used in this example.
  
  $ vi ~/.gbs.conf
  

Edit the file and match the url to the following:
  
  [repo.tizen_latest]
  url = http://download.tizen.org/snapshots/trunk/ivi/latest
  

If you have a developer account, and you are planning to use the Tizen building system, you can add your profile data also. This is an optional step for local builds.

  
  [profile.tizen]
  user = YOUR_USERNAME
  #CAUTION: please use the key name "passwd" to reset plaintext password
  passwd = YOUR_PASSWORD
  

Save the configuration file and exit the editor (in vi, first hit ESC, then type //:wq//).


=== Compiling, compiling  ===


The //gbs// will download needed dependencies from the url set up to the configuration. Thus, everything should be ready for building.

  
  $ gbs build -A i586
  

This should result in installable repository in //~/GBS-ROOT/local/repos/tizen//, containing packages built from your local source code.


==== ARM target  ====


To build the packages for ARM (armv7 hardfloat) an adaption to your gbs.conf is needed:
  
  $ vi ~/.gbs.conf
  

We need to add two new repo definitions and change the default for "repo=":

  
  
  repos = repo.arm_main, repo.arm_base
  
  [repo.arm_main]
  url = https://download.tizen.org/releases/2.0/tizen-2.0_20130219.4/repos/main/armv7l/packages/
  [repo.arm_base]
  url = https://download.tizen.org/releases/2.0/tizen-2.0_20130219.4/repos/base/armv7l/packages/
  

After these changes 
  
  $ gbs build -A armv7l
  

works.
