SDK/Tutorials/Add a new target

Revision as of 07:40, 5 January 2011

Overview

• Problem statement:

1. MeeGo SDK uses MADDE to manage multiple targets and developers are easy to switch between them. Basically a target includes 3 components: sysroot, runtime(qemu image) and toolchain. The toolchain is rarely changed during the development of a major MeeGo release like 1.1 or 1.2. For sysroot and runtime, they change daily since MeeGo release team creates daily build for different MeeGo profiles like Handset, Netbook, IVI and so on.
2. By default, the installation of MeeGo SDK will include several targets which are created together with the major MeeGo release. But if developers want to keep track the latest MeeGo status, they have to manually add latest target like daily sysroot/runtime into MeeGo SDK. Adding a new target is not straightforward and not easy for developer to do.

• This wiki page introduces a tool to easily add new target into MeeGo Linux SDK.

Pre-requisites

• Install MeeGo Linux SDK. http://wiki.meego.com/SDK/Docs/1.1/Getting_started_with_the_MeeGo_SDK_for_Linux.
• Download the meego-sdk-update-target from http://download3.meego.com/meego-sdk-update-target

Usage and examples

• Get help

./meego-sdk-update-target

1. There are some options set with default value if they are not specified on command line. You can change them for your convenience.
2. The tool only support Handset and Netbook as targets at this stage.
3. The tool is a shell script and free to change for your convenience.

• To update with a new Handset MeeGo trunk build 1.1.80.13.20110104.1 from http://repo.meego.com/MeeGo/builds/trunk/

sudo  meego-sdk-update-target -u 1.1.80.13.20110104.1 -url http://repo.meego.com/MeeGo/builds/trunk

• To update with a new Netbook MeeGo trunk-daily build trunk-daily-1.1.80.12.20101223.1 from http://download.meego.com/trunk-daily/builds/1.1.80

sudo  meego-sdk-update-target -d netbook -u trunk-daily-1.1.80.12.20101223.1 -url http://download.meego.com/trunk-daily/builds/1.1.80

• To update with a new Handset MeeGo testing-daily build testing-daily-1.1.80.13.20110104.1 from http://download.meego.com/testing-daily/builds/1.1.80

sudo  meego-sdk-update-target -d -u testing-daily-1.1.80.13.20110104.1 -url http://download.meego.com/testing-daily/builds/1.1.80

• To update with a new Handset MeeGo target with specific sysroot and runtime tarball files, you need to provide a name of the target with "-u" option.

sudo  meego-sdk-update-target -u my-target -sysroot url_to_sysroot_tar.gz -runtime url_to_runtime_tar.bz2

To create your own sysroot and runtime

• The sysroot has to be a tar.gz or tar.bz2 and can be generated by adding commands parameters to mic2:

mic-image-creator --format=fs --package=tar.gz ...

• The runtime has to be a tar.gz or tar.bz2 and can be generated by adding following commands parameters to mic2:

mic-image-creator --format=raw --package=tar.bz2 --release=release_no --compress-disk-image=none ...

• Please check help of mic-image-creator for detailed explanation of those options.

mic-image-creator --help

• You can find the ks file to create MeeGo sysroot and runtime at http://meego.gitorious.org/meego-os-base/image-configurations/trees/master/.
