#
|

# SYNOPSIS
|
||||
#
|
||||
# AX_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.
