|
# DESCRIPTION
|
|
#
|
|
# This file provides autoconf support for those applications that want to
|
|
# embed python. It supports all pythons >= 2.2 which is the first official
|
|
# release containing distutils. Version 2.2 of python was released
|
|
# December 21, 2001. Since it actually executes the python, cross platform
|
|
# configuration will probably not work. Also, most of the platforms
|
|
# supported are consistent until you look into Mac OS X. The python
|
|
# included with it is installed as a framework which is a very different
|
|
# environment to set up the normal tools such as gcc and libtool to deal
|
|
# with. Therefore, once we establish which python that we are going to
|
|
# use, we use its distutils to actually compile and link our modules or
|
|
# applications.
|
|
#
|
|
# At this time, it does NOT support linking with Python statically. It
|
|
# does support dynamic linking.
|
|
#
|
|
# This set of macros help define $PYTHON, $PYTHON_USE, $PYTHON_CSPEC and
|
|
# $PYTHON_LSPEC. $PYTHON defines the full executable path for the Python
|
|
# being linked to and is used within these macros to determine if that has
|
|
# been specified or found. These macros do execute this python version so
|
|
# it must be present on the system at configure time.
|
|
#
|
|
# $PYTHON_USE is an automake variable that defines whether Python support
|
|
# should be included or not in your application. $PYTHON_CSPEC is a
|
|
# variable that supplies additional CFLAGS for the compilation of the
|
|
# application/shared library. $PYTHON_LSPEC is a variable that supplies
|
|
# additional LDFLAGS for linking the application/shared library.
|
|
#
|
|
# The following is an example of how to set up for python usage within
|
|
# your application in your configure.in:
|
|
#
|
|
# AX_PYTHON_DEFAULT( )
|
|
# AX_PYTHON_ENABLE( ) # Optional
|
|
# AX_PYTHON_WITH( ) # Optional
|
|
# AX_PYTHON_PATH( ) # or AX_PYTHON_INSIST( )
|
|
# # if $PYTHON is not defined, then the following do nothing.
|
|
# AX_PYTHON_VERSION_ENSURE( [2.2] )
|
|
# AX_PYTHON_CSPEC
|
|
# AX_PYTHON_LSPEC
|
|
#
|
|
# The AX_PYTHON_DEFAULT sets the $PYTHON_USE to false. Thereby, excluding
|
|
# it if it was optional.
|
|
#
|
|
# The AX_PYTHON_ENABLE looks for the optional configure parameters of
|
|
# --enable-python/--disable-python and establishes the $PYTHON and
|
|
# $PYTHON_USE variables accordingly.
|
|
#
|
|
# The AX_PYTHON_WITH looks for the optional configure parameters of
|
|
# --with-python/--without-python and establishes the $PYTHON and
|
|
# $PYTHON_USE variables accordingly.
|
|
#
|
|
# The AX_PYTHON_PATH looks for python assuming that none has been
|
|
# previously found or defined and issues an error if it does not find it.
|
|
# If it does find it, it establishes the $PYTHON and $PYTHON_USE variables
|
|
# accordingly. AX_PYTHON_INSIST could be used here instead if you want to
|
|
# insist that Python support be included using the --enable-python or
|
|
# --with-python checks previously done.
|
|
#
|
|
# The AX_PYTHON_VERSION_ENSURE issues an error if the Python previously
|
|
# found is not of version 2.2 or greater.
|
|
#
|
|
# Once that these macros have be run, we can use PYTHON_USE within the
|
|
# makefile.am file to conditionally add the Python support such as:
|
|
#
|
|
# Makefile.am example showing optional inclusion of directories:
|
|
#
|
|
# if PYTHON_USE
|
|
# plugins = plugins
|
|
# src = src
|
|
# else
|
|
# plugins =
|
|
# src =
|
|
# endif
|
|
#
|
|
# SUBDIRS = . $(plugins) $(src)
|
|
#
|
|
# Makefile.am example showing optional shared library build:
|
|
#
|
|
# if PYTHON_USE
|
|
# lib_LTLIBRARIES = libElemList.la
|
|
# libElemList_la_SOURCES = libElemList.c
|
|
# libElemList_la_CFLAGS = @PYTHON_CSPEC@
|
|
# libElemList_la_LDFLAGS = @PYTHON_LSPEC@
|
|
# endif
|
|
#
|
|
# Makefile.am example showing optional program build:
|
|
#
|
|
# if PYTHON_USE
|
|
# bin_PROGRAMS = runFunc
|
|
# runFunc_SOURCES = runFunc.c
|
|
# runFunc_CFLAGS = @PYTHON_CSPEC@
|
|
# runFunc_LDFLAGS = @PYTHON_LSPEC@
|
|
# endif
|
|
#
|
|
# The above compiles the modules only if PYTHON_USE was specified as true.
|
|
# Also, the else portion of the if was optional.
