From 239b7ab0e2832fb4932542c09c5dda41b939ca83 Mon Sep 17 00:00:00 2001 From: Willem Toorop Date: Mon, 12 Sep 2011 14:26:25 +0000 Subject: [PATCH] Make pyldns work with the AX_PYTHON_DEVEL macro.

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.
