0install: Source code

Install from Source

Installing from source. Zero Install is written entirely in Python, so installing from source is quite simple.

To use Zero Install, you will need:

Python (version 2.6 or later, including any -dev package).
GnuPG (to check the digital signatures).
xdg-utils (optional; GNOME and KDE desktop integration).
PyGTK 2.12 or later (only needed for the GUI). If you have an older version of GTK, use Zero Install version 0.41 instead. Note: even if you don't use the GUI, you still need python-gobject. This is a dependency of PyGTK, but is also available separately.

Note: the last version to support Python 2.5 was 0install 1.0

If you are looking for a package, try the main downloads page.

Instructions

Download the latest .tar.bz2 archive from the download page (and the corresponding .sig file if you want to verify it), or using wget:

$ wget http://downloads.sourceforge.net/project/zero-install/injector/1.5/zeroinstall-injector-1.5.tar.bz2
$ wget http://downloads.sourceforge.net/project/zero-install/injector/1.5/zeroinstall-injector-1.5.tar.bz2.sig

Check that the signature is correct using GPG (this also ensures that GPG is installed correctly). You'll need my GPG key, which you can download and import using --recv-key (or manually):

$ gpg --recv-key --keyserver pgp.mit.edu CA74D8BA
$ gpg zeroinstall-injector-1.5.tar.bz2.sig
gpg: Signature made Thu 29 Dec 2011 12:21:10 GMT using RSA key ID CA74D8BA
gpg: Good signature from "Thomas Leonard <XXXXX@gmail.com>"
gpg: Good signature from "Thomas Leonard <XXXXX@users.sourceforge.net>"
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: DA98 25AE CAD0 8975 7CDA  BD8E 0713 3F96 CA74 D8BA

The warning is just to tell you that you haven't yet established that the key really belongs to me (ultra-paranoid users will now cross-check the finger-print using some other source of information).

You should now extract the archive, and change directory inside it:

$ tar xjf zeroinstall-injector-1.5.tar.bz2
$ cd zeroinstall-injector-1.5

Installing normally

Installing without root access

For a normal install, either su to root, install, and exit from root, or use sudo:

$ sudo python setup.py install

If you don't have the root password, use this command. You'll need to make sure that ~/bin is in $PATH in this case.

$ python setup.py install --home ~ --install-data ~/.local
$ export PATH=$HOME/bin:$PATH

Logging out and back in again will ensure $PATH and the Applications menu get updated correctly, on Ubuntu at least.

error: invalid Python installation: unable to open /usr/lib/python2.5/config/Makefile: You need to install the python-dev package, not just python.
package init file 'zeroinstall/0launch-gui/__init__.py' not found (or not a regular file): This is just a warning and is harmless.

You now have some new commands: 0launch, which takes the URL of a program and runs it, 0alias, which lets you use short names instead of URLs, and 0install, which provides access to other features.
