What could be done is to use out-of-tree “VPATH” builds [1] to configure
and build with both python versions in different directories in the
‘%build’ phase and run ‘make install’ in each of these directories in
the ’%install’ phase.
Maybe something like this (totally untested :-)):
--8<---------------cut here---------------start------------->8---
%build
mkdir py2 && cd py2
../%configure PYTHON=/path/to/python2
%make_build
cd ..
mkdir py3 && cd py3
../%configure PYTHON=/path/to/python3
%make_build
cd ..
%install
%make_install -C py2
%make_install -C py3
--8<---------------cut here---------------end--------------->8---
It seems not ideal to handle distro specific packaging guidelines on the
upstream configuration side. As a consequence I would rather avoid
adding macros to be run at configure time.
WDYT?
