Author: gjanssens
Date: 2013-12-14 11:40:54 -0500 (Sat, 14 Dec 2013)
New Revision: 23560
Trac: http://svn.gnucash.org/trac/changeset/23560
Added:
gnucash/trunk/macros/ax_pkg_swig.m4
gnucash/trunk/macros/ax_python_devel.m4
gnucash/trunk/macros/ax_swig_python.m4
Removed:
gnucash/trunk/macros/ac_pkg_swig.m4
gnucash/trunk/macros/ac_python_devel.m4
Modified:
gnucash/trunk/configure.ac
Log:
SWIG version updates
- move the swig version check after the guile checks
this allows us to check for a different version of swig
based on the guile version that was detected
- use more recent autoconf macros for swig (from the autotools archive)
this give us more flexible error reporting
Modified: gnucash/trunk/configure.ac

+# DESCRIPTION
+#
+# This macro searches for a SWIG installation on your system. If found,

+# or higher.
+#
+# As usual, action-if-found is executed if SWIG is found, otherwise
+# action-if-not-found is executed.

+# 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.

+# SYNOPSIS
+#
+# AX_SWIG_PYTHON([use-shadow-classes = {no, yes}])
+#
+# DESCRIPTION
+#
+# Checks for Python and provides the $(AX_SWIG_PYTHON_CPPFLAGS), and
+# $(AX_SWIG_PYTHON_OPT) output variables.
+#
+# $(AX_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 AX_SWIG_MULTI_MODULE_SUPPORT macro) use
+# $(AX_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.
