|
# SYNOPSIS
|
|
#
|
|
# AC_PYTHON_DEVEL([version])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Note: Defines as a precious variable "PYTHON_VERSION". 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.
