Introduction
The usual way of developing Maemo applications is using or Scratchbox or MADDE, which are quite heavy for Python development. An alternative is using stdeb, a set of extensions to distutils that allows generating debian packages, both binary and source, that can be installed on the device or sent to the extras-devel repository.
This tutorial will show how to integrate it into your project, building the packages and uploading it to extras-devel.
Prerequisites
This tutorial is aimed at Debian-based systems, as some stdeb commands requires the dpkg tools installed. In
Also, you should get the git version of stdeb to use the debianize command, as it is a new addition and not yet available in the repositories.
Preparing the package
As stdeb extends distutils, it is necessary that you have a working setup.py script. For our example application, which consists of a single script named "myscript" and support files like .desktop and an icon, the setup.py will look like this:
from distutils.core import setup setup( name='myscript', author='Lauro Moura', author_email='lauro.neto@donotspamme.com', scripts=['myscript'], data_files=[('share/applications/hildon', ['myscript.desktop']), ('share/pixmaps', ['myscript.png'])], )
A file named stdeb.cfg in the same directory as setup.py is required, with stdeb maemo-specific options. A detailed list of options can be found in the stdeb website.
[DEFAULT] XS-Python-Version: 2.5 # Only version currently supported by pymaemo. Package:myscript # Binary package name. stdeb adds the prefix "python-" by default Section: user/other # Section should start with user/ to appear in the menu. Depends: python-gtk2 # add extra dependencies here
Building the packages
The basic command is
python setup.py --command-packages=stdeb.command bdist_deb
It'll create a folder called deb_dist with the source and binary packages. Alternatively, the "sdist_dsc" command will create only the source package.
After generating, you can copy the package to your device and install it (requires an SSH server):
$ scp myscript_0.0.0_all.deb root@<n900 ip>:/root $ ssh root@<n900 ip> # dpkg -i myscript_0.0.0_all.deb
Building a basic debian directory
Another useful command is debianize. It will read the configuration file and write a directory named debian in the same directory. This can be used for manually creating the packages using dpkg tools directly.
Note: sdist_dsc and bdist_deb do not use this directory, generating a new one in the source dir under deb_dist/.
Uploading to extras
To upload to extras, use the debianize command and then call dpkg-buildpackage:
$ dpkg-buildpackage -rfakeroot -uc -us -S
This command will create the .dsc, .tar.gz and .changes files that can be used to upload the application to extras-devel
Future work
Support for non-debian systems.
