Python Wheels in fedora
Starting with Fedora 22, Python packages will install itself into buildroot via Python wheels[1]. Wheels are the new binary distribution format for python modules, note that as such they are not suitable for use as Source archive. The text below describes the minimal specfile changes needed.
BuildRequires
Packages will now BuildRequire python-pip and python-wheel:
BuildRequires: python-pip BuildRequires: python-wheel
Build section
Packages will now use the bdist_wheel command, instead of install, this creates a wheel in the dist directory. A minimal build section thus becomes:
%{__python2} setup.py bdist_wheel
%if 0%{?with_python3}
pushd %{py3dir}
%{__python3} setup.py bdist_wheel
popd
%endif
Install section
Packages will now use pip to install the newly created wheel. A minimal install section thus becomes:
%if 0%{?with_python3}
pushd %{py3dir}
pip3 install -I dist/%{python3_wheelname} --root %{buildroot} --strip-file-prefix
popd
%endif
pip2 install -I dist/%{python2_wheelname} --root %{buildroot} --strip-file-prefix
The --strip-file-prefix option is currently downstream only modification that strips given prefix from files in wheel RECORD.[2]
Files section
You may also need to add the following entries to the files section:
%{python2_sitelib}/%{name}-%{version}.dist-info/
%{python3_sitelib}/%{name}-%{version}.dist-info/
