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?
