(Reminder, various distribution packaging guidelines require use of explicit python version and don't allow '#!/usr/bin/env python', regardless of how handy that idiom may be.) glusterfs.spec(.in) package python{2,3}-gluster and python2 or python3 dependencies as appropriate. configure(.ac): + test for and use python2 or python3 as appropriate. If build machine has python2 and python3, use python3. Override by setting PYTHON=/usr/bin/python2 when running configure. + PYTHONDEV_CPPFLAGS from python[23]-config --includes is a better match to the original python sysconfig.get_python_inc(). All those other extraneous flags breaks the build. + Only change the shebangs once. Changing them over and over again, e.g., during a `make glusterrpms` in extras/LinuxRPM just sends make (is it really make that's looping?) into an infinite loop. If you figure out why, let me know. + Oldest python2 is python2.6 on CentOS 6 and Debian 8 (Jessie). Everything else has 2.7 or 3.x + logic from https://review.gluster.org/c/glusterfs/+/21050, which needs to be removed/merged after that patch is merged. Builds on CentOS 6, CentOS 7, Fedora 28, Fedora rawhide, and the mysterious RHEL > 7. Change-Id: Idae21d3b6f58b32372e1daa0d234e491e563198f updates: #411 Signed-off-by: Kaleb S.
