Subject: [WIP 3/8] guix: python-build-system: Import setuptools before calling `setup.py'.
Date: Mon, 10 Oct 2016 16:57:14 +0200 [thread overview]
Message-ID: <1476111439-20812-4-git-send-email-h.goebel@crazy-compilers.com> (raw)
In-Reply-To: <1476111439-20812-1-git-send-email-h.goebel@crazy-compilers.com>
From: Marius Bakke <mbakke@fastmail.com>
This is needed for packages using "distutils" instead of "setuptools" since
the former does not understand the "--single-version-externally-managed"
flag. Also export __file__ since it will be unset when setup.py is called from
python "exec".
* guix/build/python-build-system.scm (call-setuppy): extend "python setup.py"
call to import setuptools, export __file__, and call setup.py from
setuptools python environment.
