# The plugin supports both Python 2 and Python 3
#
# In theory we could have arbitrary combinations of python versions for each
# of:
# - python version used when running scripts during the build (e.g. to
# generate code)
# - python version we compile and link the plugin against
# - when running the plugin with the cpychecker script, the python version
# that the code is being compiled against
#
# However, to keep things simple, let's assume for now that all of these are
# the same version: we're building the plugin using the same version of Python
# as we're linking against, and that the cpychecker will be testing that same
# version of Python
#
# By default, build against "python", using "python-config" to query for
# compilation options. You can override this by passing other values for
# PYTHON and PYTHON_CONFIG when invoking "make" (or by simply hacking up this
# file): e.g.
# make PYTHON=python3 PYTHON_CONFIG=python3-config all
# The python interpreter to use:
PYTHON=python
# The python-config executable to use:
PYTHON_CONFIG=python-config
#PYTHON=python3

# Notes to self on making a release
# ---------------------------------
#
# Before tagging:
#
# * update the version/release in docs/conf.py
#
# * update the version in gcc-python-plugin.spec
#
# * add release notes to docs
#
# Test the candidate tarball via a scratch SRPM build locally (this
# achieves test coverage against python 2 and 3, for both debug and
# optimized python, on one arch, against the locally-installed version of
# gcc):
#
# $ make srpm VERSION=fixme
#
# $ make rpm VERSION=fixme
#
# Test the candidate tarball via a scratch SRPM build in Koji (this
# achieves test coverage against python 2 and 3, for both debug and
# optimized python, on both i686 and x86_64, against another version of
# gcc):
#
# $ make koji VERSION=fixme
#
# After successful testing of a candidate tarball:
#
# * push the tag:
#
# $ git push --tags
#
# * upload it to https://fedorahosted.org/releases/g/c/gcc-python-plugin/
# via:
#
# $ scp gcc-python-plugin-$(VERSION).tar.gz dmalcolm@fedorahosted.org:gcc-python-plugin
#
# * add version to Trac: https://fedorahosted.org/gcc-python-plugin/admin/ticket/versions
#
# * update release info at https://fedorahosted.org/gcc-python-plugin/wiki#Code
#
# * send release announcement:
#
# To: gcc@gcc.gnu.org, gcc-python-plugin@lists.fedorahosted.org, python-announce-list@python.org
# Subject: ANN: gcc-python-plugin $(VERSION)
# (etc)
#
# * build it into Fedora
# Utility target, for building test rpms:
srpm:
rpmbuild -bs gcc-python-plugin.spec
# Perform a test rpm build locally:
rpm:
rpmbuild -ba gcc-python-plugin.spec
# Perform a test (scratch) build in Koji:
# f16 was gcc 4.6, but this has been deleted from Koji
# f17: gcc 4.7
# f19: gcc 4.8
