7# AC_PROG_SWIG([major.minor.micro])
8#
9# DESCRIPTION
10#
11# This macro searches for a SWIG installation on your system. If found you
12# should call SWIG via $(SWIG). You can use the optional first argument to
13# check if the version of the available SWIG is greater than or equal to
14# the value of the argument. It should have the format: N[.N[.N]] (N is a
15# number between 0 and 999. Only the first N is mandatory.)
16#
17# If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks that
18# the swig package is this version number or higher.
19#
20# In configure.in, use as:
21#
22# AC_PROG_SWIG(1.3.17)
23# SWIG_ENABLE_CXX
24# SWIG_MULTI_MODULE_SUPPORT
25# SWIG_PYTHON

5# SYNOPSIS

7# AC_PYTHON_DEVEL([version])
8#
9# DESCRIPTION
10#
11# Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
12# in your configure.ac.
13#
14# This macro checks for Python and tries to get the include path to
15# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS)
16# output variables. It also exports $(PYTHON_EXTRA_LIBS) and
17# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
18#
19# You can search for some particular version of Python by passing a
20# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
21# note that you *have* to pass also an operator along with the version to
22# match, and pay special attention to the single quotes surrounding the
23# version number. Don't use "PYTHON_VERSION" for this: that environment
24# variable is declared as precious and thus reserved for the end-user.
25#
26# This macro should work for all versions of Python >= 2.1.0. As an end
27# user, you can disable the check for the python version by setting the
28# PYTHON_NOVERSIONCHECK environment variable to something else than the
29# empty string.
30#
31# If you need to use this macro for an older Python version, please
32# contact the authors. We're always open for feedback.

12# sets the PTHREAD_LIBS output variable to the threads library and linker
13# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
14# flags that are needed. (The user can also force certain compiler
15# flags/libs to be tested by setting these environment variables.)
16#
17# Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is
18# needed for multi-threaded programs (defaults to the value of CC
19# respectively CXX otherwise). (This is necessary on e.g. AIX to use the
20# special cc_r/CC_r compiler alias.)
21#
22# NOTE: You are assumed to not only compile your program with these flags,
23# but also to link with them as well. For example, you might link with
24# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
25# $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
26#
27# If you are only building threaded programs, you may wish to use these
28# variables in your default LIBS, CFLAGS, and CC:
29#
30# LIBS="$PTHREAD_LIBS $LIBS"
31# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
32# CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS"
33# CC="$PTHREAD_CC"
34# CXX="$PTHREAD_CXX"
35#
36# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
37# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
38# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
39#
40# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
41# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
42# PTHREAD_CFLAGS.
43#
44# ACTION-IF-FOUND is a list of shell commands to run if a threads library
45# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
46# is not found. If ACTION-IF-FOUND is not specified, the default action
47# will define HAVE_PTHREAD.
48#
49# Please let the authors know if this macro fails on any platform, or if
50# you have any other suggestions or comments. This macro was based on work
51# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
52# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
53# Alejandro Forero Cuervo to the autoconf macro repository. We are also
54# grateful for the helpful feedback of numerous users.

5# SYNOPSIS
6#
7# AX_PYTHON_DEVEL([version[,optional]])
8#
9# DESCRIPTION
10#
11# Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
12# in your configure.ac.
13#
14# This macro checks for Python and tries to get the include path to
15# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LIBS) output
16# variables. It also exports $(PYTHON_EXTRA_LIBS) and
17# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
18#
19# You can search for some particular version of Python by passing a
20# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
21# note that you *have* to pass also an operator along with the version to
22# match, and pay special attention to the single quotes surrounding the
23# version number. Don't use "PYTHON_VERSION" for this: that environment
24# variable is declared as precious and thus reserved for the end-user.
25#
26# By default this will fail if it does not detect a development version of
27# python. If you want it to continue, set optional to true, like
28# AX_PYTHON_DEVEL([], [true]). The ax_python_devel_found variable will be
29# "no" if it fails.
30#
31# This macro should work for all versions of Python >= 2.1.0. As an end
32# user, you can disable the check for the python version by setting the
33# PYTHON_NOVERSIONCHECK environment variable to something else than the
34# empty string.
35#
36# If you need to use this macro for an older Python version, please
37# contact the authors. We're always open for feedback.

5# SYNOPSIS
6#
7# SWIG_PYTHON([use-shadow-classes = {no, yes}])
8#
9# DESCRIPTION
10#
11# Checks for Python and provides the $(SWIG_PYTHON_CPPFLAGS), and
12# $(SWIG_PYTHON_OPT) output variables.
13#
14# $(SWIG_PYTHON_OPT) contains all necessary SWIG options to generate code
15# for Python. Shadow classes are enabled unless the value of the optional
16# first argument is exactly 'no'. If you need multi module support
17# (provided by the SWIG_MULTI_MODULE_SUPPORT macro) use
18# $(SWIG_PYTHON_LIBS) to link against the appropriate library. It contains
19# the SWIG Python runtime library that is needed by the type check system
20# for example.
