Python Setuptools

Python packages can be installed with python setuptools, which uses distutils as the standard library.  To do this generate a setup.py file, and then create a specfile just like you normally would.  Normally, the specfile builds c, so to build python it needs to be altered a little bit.  First add the following line to the very start of the specfile.  I had to split into two because it is somewhat long.

%{!?python_sitelib: %define python_sitelib %(%{__python} -c
"from distutils.sysconfig import get_python_lib; print get_python_lib()")}

The rest is the same except for the section where the package is built.  Here is an example of part of one my specfiles.

%prep
%setup -q

%build
%{__python} setup.py build

%install
rm -rf $RPM_BUILD_ROOT
%{__python} setup.py install -O1 --skip-build --root $RPM_BUILD_ROOT

%clean
rm -rf $RPM_BUILD_ROOT

As you may have noticed the %prep and %clean sections are still the same.  When installing you have to tell distutils it doesn’t need to build, because it already has previously, and specify the root dir.  I managed to figure this out by reverse engineering this pungi specfile.

    I packaged an RPM for varnish 2.1.1-1. In case you are interested to obtain it, just contact me. You saved me lots of effort and time by this tutorial, thank you so much 🙂

    Thanks for sharing this. The fungi spec file link is broken: I had to use http://oss.tresys.com/projects/clip/browser/packages/pungi/pungi.spec to have a look at it. Cheers.

    Good tutorial. But you have not mentioned about creating rpm after editing spec file. Is there a way to call spec file using inbuilt command “bdist_rpm” or should I have to use “rpmbuild” to generate package? In both the cases an example would have be helpful for new comer like me.

    Nice tutorial though.
