Is it possible to get PyROOT to work with Python2.7 and 3.4 without duplicating the whole ROOT (v5.34.32) installation? This is easy to do for packages installed by pip/pip3, for instance, because they end up in Python-version-specific directories.
Thanks for your reply. I ended up copying ROOT.py and libPyROOT.so into $PYTHON_PREFIX/lib/python-X.Y/site-packages, which is where pip installs packages.
