SDK/MeeGo 1.1 Application SDK Project Plan

Revision as of 08:18, 17 June 2010

MeeGo 1.1 Application SDK Project Plan

This document describes the MeeGo 1.1 Application SDK contents and how we get there.

Mission

• Delivering MeeGo SDK for developers to develop MeeGo Applicaitons at best chance running across platforms and segments(netbook, handset, tablet and TV..).
• MeeGk SDK helps to shape MeeGo APIs and compliance.

MeeGo 1.1 Application SDK is going to be the first official Application SDK release in MeeGo. The Application SDK is mainly targetted for Application developers who are interested in creating new applications for MeeGo platform. They might not be so interested in Open Source but are hoping to sell their applications on OVI Store or equivalent.

The application SDK should run on multiple different host environments (Linux, Win, Mac). In general all the parts of the Application SDK should run similarly on all the hosts! Still it is possible that we will have features that will only work on some of the hosts or with only some of the targets. This aspect should be considered in the SDK architecture.

Key Drivers

• MeeGo Application SDK which allows developers to use any host and develop to any target with a similar manner.
  • The host OSs include Windows, Linux (Ubuntu and Fedora??) and Mac OS.
  • The targets include CDK,Aava and N900 or simulators/emulators.
  • Support both 64bits and 32 bits host machines
  • Have a possibility for allowing features that only work on specific hosts or for specific targets
• SDK development process agreed and active
  • How are decisions made etc - suggest following the open process defined for MeeGo at http://meego.com/developers/meego-roadmap

Architecture of MeeGo SDK =

Integration, Distribution and Installation of MeeGo SDK

How MeeGo SDK components to be integrated and distributed

• Some components should be put into OBS and maintained there as RPMs, like
  • QT Creator
  • QEMU
  • Xephry
  • Mad-developer

• Or just be packaged as tarball and maintained in gitorious, like
  • Madde

• Some components should be created based on the MeeGo build by using tools/scripts, like
  • Simulator images
  • QEMU/emulator images
  • Sysroots
  • Toolchains

• MeeGo Application SDK will be built in sync with the MeeGo weekly builds. ...
• Installer of SDK should be developed to package everything of MeeGo SDK into one package (bin)
• End users just need to download the SDK Installers (for Windows, Linux and Mac), and then execute it to install MeeGo SDK on hosts.

Quality Assurance

How are the releases tested? + everything related...

Components / Tasks

The components of MeeGo Application SDK are listed in this section. Each component should have a responsible, package maintainer and some status information as we go along.

Qt Creator

Qt Creator is the chosen IDE for MeeGo Application SDK.

• Key Requirements for MeeGo1.1:
  • Support mutiple targets, like N900, CDK and Aava;
  • Support remote deploying and debugging.
• Responsible: Maurice Kalinowski
• Package Maintainer: Fathi Boudra
• Status:
  • Not part of the OBS builds yet
  • Adding MADDE targets seems somewhat complicated

Compiling plugins

The compiling plugins are used for compiling and packaging the software with different tools (MADDE / OBS). The end result should be installable application RPM.

MADDE plugin

This plugin uses MADDE for compiling and packaging the software.

• Responsible: unknown
• Package Maintainer: unknown
• Status:
  • Just a dream

OBS plugin

This plugin uses OBS for compiling and packaging the software.

• Responsible: unknown
• Package Maintainer: unknown
• Status:
  • Just a dream

Run plugins

The run plugins are used for installing, running and debugging the software. In general the plugin could use e.g. MADDE to provide this feature.

Qemu plugin

This plugin provides the possibility to use Qemu for "Run plugin" features. This plugin uses MADDE.

• Responsible: unknown
• Package Maintainer: unknown
• Status:
  • Just a dream

Device run plugin

This plugin provides the possibility to use real devices for "Run plugin" features. This plugin uses MADDE.

• Responsible: unknown
• Package Maintainer: unknown
• Status:
  • Just a dream

Xephyr plugin

This plugin provides the possibility to use Xephyr (and chroot) for "Run plugin" features.

• Responsible: unknown
• Package Maintainer: unknown
• Status:
  • Just a dream

Debugging plugins

These plugins are used for debugging in Qt Creator. These could use MADDE for running the debuggers etc. and different kind of methods for visualization.

Valgrind

TODO

• Responsible: unknown
• Package Maintainer: unknown
• Status:
  • Just a dream

Oprofile

TODO

• Responsible: unknown
• Package Maintainer: unknown
• Status:
  • Just a dream

MADDE

MADDE is multiplatform toolset for compiling, running, debugging and testing. It provides same API for underlying tools on all the host platforms. MADDE can be used from commandline or from IDE. Primary IDE is Qt Creator but others, like eclipse, can be supported too (although not in this project).

• Responsible: Jari Ihatsu
• Package Maintainer: Fathi Boudra
• Status:
  • We have a build of MADDE that includes MeeGo ARM target
  • Not part of the OBS builds yet

Compiling

Compiling is done with combination of a cross-compiler and a sysroot which includes target headers and libraries. Compilers come with MADDE.

Hosts and Targets

Status of the supported hosts and targets:

Sysroots

Sysroot is a collection of target headers and libraries which are used by the compilers to compile the software.

Sysroot responsibles and statuses:

Cross-Compilers

Cross-compiler status per host and responsibles:

Running

With MADDE the application developer can create RPM package on any host environment, transfer and run the software on the device or in the emulation.

RPM support

RPM packager is created with ...

The status of the RPM support on different host platforms.

Targets (devices / Emulation)

Aava

N900

Qemu

The status and the responsible of the Qemu on different host platforms.

= Qemu Images =

The Qemu images are images used with the QEMU full system emulation. The images are as similar as possible to the actual device images.

Testing & Debugging tools

What do we have?

Documentation of MeeGo SDK

The Documentation of MeeGo SDK tells how to install/set up MeeGo SDK on any host machine, how to get started to use SDK to create first MeeGo applicaiton, including creating project, editing, compiling and building and remotely deploying and debuging applicaton.

Supported APIs are also important part of SDK docmentation.
