Open development

Maemo is developed as an open collaboration between Nokia and many generous volunteer programmers, designers, and users. Most of Maemo's components are open source, which gives users and developers the freedom and flexibility to contribute to and modify the platform's core development.

Open development is the goal and open source is a consequence of it. Easier said than done when you need to deliver commercial and competitive products on time, but the Maemo team is trying and improving on every release.

[edit] In practice

If you want to get involved you need to find first the most recent source code available:

  • The source code of OSS components shipped in Maemo releases can be found at e.g. Maemo 5.
  • The current development of certain components can be found at Maemo on Gitorious. See the list of projects above for more details.
  • Cross-Reference contains searchable source dumps of the open packages of most Maemo releases. This website is incredibly useful; you can search for any given identifier (a name of a C function, for example) and it will find the declaration and all uses of that function for you.

If you have patches for upstream components it is better to submit them directly upstream, unless they are indeed specific to Maemo:

[edit] MeeGo

  • Meego Cross-Reference
  • MeeGo on Gitorious is where open development for Meego happens. For example, sources for the Meego Touch Framework are there. You can also find sources for some middleware components used in Maemo that have been partially opened in Meego, like MCE.
  • Qt on Gitorious Qt is an important part of the newer Maemo/Meego releases; you can find its source here.

[edit] Projects developed openly

[edit] Community projects developed openly

There are dozens of community projects developed openly. Learn more about them at (this should link to another page to keep this one around Nokia projects).

[edit] Extras

Main article: Extras

The sources from all free packages in the extras and extras-devel repositories are available here.

On an N900, or scratchbox, if you have correctly added the extras-devel repository to sources.list, you can also get any packages source by writing the following on a shell:

apt-get source <packagename>

There are also some Garage projects using Git as version control system.

Some developers also use gitorious or github.

[edit] Community SSU

The community SSU has its own Gitorious project. You can find all modifications to the Maemo open components (and sources of those), as well as replacement components and hacked bits, all there.
