Notes for developers

  • maemo 4.0 alpha requires Scratchbox Apophis R4 or later
  • Nokia Binaries are not included

Notes about compatibility

The SDK is in a preview of Maemo 4.0 'chinook' SDK. It has been released with lighter quality checks than normal maemo SDK. It contains a mixture of maemo 3.1 'bora' and maemo 4.0 'chinook' APIs, so software ported to this SDK will probably not be runnable in any official Internet Tablet OS version.


The maemo 4.0 alpha SDK provides an installer script that can be used to install the SDK. This is the only supported installation method.

Package Repositories

The maemo 4.0 alpha SDK installer script will automatically setup and configure the /etc/apt/sources.list files inside your Scratchbox targets. After installation you should be able to use the apt-get tools inside the Scratchbox to access the components in the maemo 3.x bora and Sardine repositories.
