#
|

# SYNOPSIS
|
||||
#
|
||||
# AC_PROG_SWIG([major.minor.micro])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro searches for a SWIG installation on your system. If
|
||||
# found you should call SWIG via $(SWIG). You can use the optional
|
||||
# first argument to check if the version of the available SWIG is
|
||||
# greater than or equal to the value of the argument. It should have
|
||||
# the format: N[.N[.N]] (N is a number between 0 and 999. Only the
|
||||
# first N is mandatory.)
|
||||
#
|
||||
# If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks
|
||||
# that the swig package is this version number or higher.
|
||||
#
|
||||
# In configure.in, use as:
|
||||
#
|
||||
# AC_PROG_SWIG(1.3.17)
|
||||
# SWIG_ENABLE_CXX
|
||||
# SWIG_MULTI_MODULE_SUPPORT

# 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.

##### http://autoconf-archive.cryp.to/swig_python.html
|

#
|
||||
# SYNOPSIS
|
||||
#
|
||||
# SWIG_PYTHON([use-shadow-classes = {no, yes}])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Checks for Python and provides the $(SWIG_PYTHON_CPPFLAGS), and
|
||||
# $(SWIG_PYTHON_OPT) output variables.
|
||||
#
|
||||
# $(SWIG_PYTHON_OPT) contains all necessary SWIG options to generate
|
||||
# code for Python. Shadow classes are enabled unless the value of the
|
||||
# optional first argument is exactly 'no'. If you need multi module
|
||||
# support (provided by the SWIG_MULTI_MODULE_SUPPORT macro) use
|
||||
# $(SWIG_PYTHON_LIBS) to link against the appropriate library. It
|
||||
# contains the SWIG Python runtime library that is needed by the type
|
||||
# check system for example.
