Rename configure.in to configure.ac The old name was deprecated in 2013. See-also: https://lists.gnu.org/archive/html/automake/2013-05/msg00049.html Suggested-by: lintian, aclocal X: libpst source: deprecated-configure-filename aclocal: warning: autoconf input should be named 'configure.ac', not 'configure.in'

# SYNOPSIS
#
#   AX_BOOST_PYTHON
#
# DESCRIPTION
#
#   This macro checks to see if the Boost.Python library is installed. It
#   also attempts to guess the correct library name using several attempts.
#   It tries to build the library name using a user supplied name or suffix
#   and then just the raw library.
#
#   If the library is found, HAVE_BOOST_PYTHON is defined and
#   BOOST_PYTHON_LIB is set to the name of the library.
#
#   This macro calls AC_SUBST(BOOST_PYTHON_LIB).
#
#   In order to ensure that the Python headers and the Boost libraries are
#   specified on the include path, this macro requires AX_PYTHON_DEVEL and
#   AX_BOOST_BASE to be called.
