# HG changeset patch # User Roger Pau Monne <roger.pau@xxxxxxxxxxxxx> # Date 1329999113 -3600 # Node ID 6688425179fdf1fb39f3093362ba8053d1ae4f21 # Parent 1b68427875f7ffe3025ea13c7f6e8cf71ce54769 autoconf: change python configure testing Switch from our custom m4 macro to ax_python_devel.m4 found in: http://www.gnu.org/software/autoconf-archive/ax_python_devel.html This provides the same set of test but uses python distutils instead of python-config. This change will also force users to switch from setting PYTHON env variable to using PYTHON_VERSION, which has to contain the python version to use (e.g.: '2.6'), if the user has several python versions installed and would like to use one different than the default.

Don't override it +# in your configure.ac. +# +# This macro checks for Python and tries to get the include path to +# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS) +# output variables. It also exports $(PYTHON_EXTRA_LIBS) and +# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code. +# +# You can search for some particular version of Python by passing a +# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please +# note that you *have* to pass also an operator along with the version to +# match, and pay special attention to the single quotes surrounding the +# version number. Don't use "PYTHON_VERSION" for this: that environment +# variable is declared as precious and thus reserved for the end-user. +# +# This macro should work for all versions of Python >= 2.1.0. As an end +# user, you can disable the check for the python version by setting the +# PYTHON_NOVERSIONCHECK environment variable to something else than the +# empty string. +# +# If you need to use this macro for an older Python version, please +# contact the authors.

Don't override it +# in your configure.ac. +# +# This macro checks for Python and tries to get the include path to +# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS) +# output variables. It also exports $(PYTHON_EXTRA_LIBS) and +# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code. +# +# You can search for some particular version of Python by passing a +# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please +# note that you *have* to pass also an operator along with the version to +# match, and pay special attention to the single quotes surrounding the +# version number. Don't use "PYTHON_VERSION" for this: that environment +# variable is declared as precious and thus reserved for the end-user. +# +# This macro should work for all versions of Python >= 2.1.0. As an end +# user, you can disable the check for the python version by setting the +# PYTHON_NOVERSIONCHECK environment variable to something else than the +# empty string. +# +# If you need to use this macro for an older Python version, please +# contact the authors. We're always open for feedback. +# +# LICENSE +# +# Copyright (c) 2009 Sebastian Huber <sebastian-huber@xxxxxx> +# Copyright (c) 2009 Alan W.
