From c577ad692f36cedbcc3378b86e1af237402b0083 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Fri, 28 Dec 2018 18:01:31 +0100 Subject: [PATCH] package/pkg-python: use --single-version-externally-managed for host setuptools Currently, host Python packages that use setuptools are installed as Python Eggs, i.e they are installed in $(HOST_DIR)/lib/python2.7/site-packages/Something-.egg. Once installed, each Python Egg is registered to a file called $(HOST_DIR)/lib/python2.7/site-packages/easy-install.pth. This file is read by the Python interpreter so that the installation location of each Egg is added to the Python path, and can be found by the Python interpreter. However, the fact that the installation of different Python modules need to update a common file is clearly not compatible with per-package directories and top-level parallel build. To fix this, we avoid using Python Eggs using the same --single-version-externally-managed option that we use for target modules. This option is normally meant for distributions packaging Python modules, and can therefore only be used if either --record (to record the list of files being installed) or --root is passed. --root=/ works fine and was suggested by https://stackoverflow.com/questions/6301003/stopping-setup-py-from-installing-as-egg/33791008#33791008. With this change, host Python modules installed by setuptools are now installed in the "regular" way, i.e directly in $(HOST_DIR)/lib/python2.7/site-packages/mako for host-python-mako. This makes the installation of host Python modules more similar to the one of target modules, and makes it compatible with per-package directory support and top-level parallel build.
