Hello,
I just subscribed yesterday, having being redirected here from
the python-tutor ML. I hope this is the right place to ask the question
I am struggling with.
I am trying to package a program I wrote for debian. It's my
**very first time** with packaging at all, and also with distutils, so
I followed online documentation to get something done. It work-ish'ed,
but I am struggling with a problem on dependencies.
To write my setup.py script I followed this:
http://packages.python.org/distribute/setuptools.html#automatic-script-creation
In the section on dependencies it says: "If your project
depends on packages that aren’t registered in PyPI, you may
still be able to depend on them, as long as they are available for
download as an egg, in the standard distutils sdist format, or as a
single .py file. You just need to add some URLs to the dependency_links
argument to setup()."
My question is: how do I list dpendencies that are not python
code? For example: say my program needs to launch at some point another
program like for example inkscape, is there a way to specify this in
the setup.py file, or am I out of luck and my only chance is to list it
in the debian directory half-way through the process of converting my
code to a .deb package?
The text you find is still talking about python packages. It means:
when you depend on python packages that are not registered on PyPI, you
can use the dependency_links argument.
It will not work for inkscape.
As an example, when I need some ldap integration then in my setup.py I
can list python-ldap as a dependency. This python package will then be
installed. But that python-ldap package itself will fail to install
when you do not have the necessary ldap bindings installed on your OS
(it would fail in the compile step then, hopefully with a clear error
message). There is no way that I know for the python-ldap package to
declare such an OS-dependency.
Also, another question out of scientific curiosity. On a
debian-based distro, if a python module is installed via PyPI, will it
be "seen" and handled by apt-get / synaptic as if it were installed
from a .deb package? In other words: would a user be able to execute
`apt-get remove xxxx` if xxxx has been installed with python
easy_install xxxx`?
No, sorry, that won't work. The two are completely separate.
Thank you in advance for your help!
