# =========================================================================== # http://autoconf-archive.cryp.to/ac_python_devel.html # =========================================================================== # # 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. # # LICENSE # # Copyright (c) 2009 Sebastian Huber # Copyright (c) 2009 Alan W.

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 MacOSX. 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: # # AZ_PYTHON_DEFAULT( ) # AZ_PYTHON_ENABLE( ) # Optional # AZ_PYTHON_WITH( ) # Optional # AZ_PYTHON_PATH( ) # or AZ_PYTHON_INSIST( ) # # if $PYTHON is not defined, then the following do nothing. # AZ_PYTHON_VERSION_ENSURE( [2.2] ) # AZ_PYTHON_CSPEC # AZ_PYTHON_LSPEC # # The AZ_PYTHON_DEFAULT sets the $PYTHON_USE to false. Thereby, excluding # it if it was optional. # # The AZ_PYTHON_ENABLE looks for the optional configure parameters of # --enable-python/--disable-python and establishes the $PYTHON and # $PYTHON_USE variables accordingly. # # The AZ_PYTHON_WITH looks for the optional configure parameters of # --with-python/--without-python and establishes the $PYTHON and # $PYTHON_USE variables accordingly. # # The AZ_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. AZ_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 AZ_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. # # LICENSE # # Copyright (c) 2008 Robert White # Copyright (c) 2008 Dustin J.
