- # SYNOPSIS
- #
- # AX_PROG_PYTHON_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
- #
- # DESCRIPTION
- #
- # Makes sure that python supports the version indicated. If true the shell
- # commands in ACTION-IF-TRUE are executed. If not the shell commands in
- # ACTION-IF-FALSE are run. Note if $PYTHON is not set (for example by
- # running AC_CHECK_PROG or AC_PATH_PROG) the macro will fail.
- #
- # Example:
- #
- # AC_PATH_PROG([PYTHON],[python])
- # AX_PROG_PYTHON_VERSION([2.4.4],[ ... ],[ ... ])
- #
- # This will check to make sure that the python you have supports at least
- # version 2.4.4.
- #
- # NOTE: This macro uses the $PYTHON variable to perform the check.
- # AX_WITH_PYTHON can be used to set that variable prior to running this
- # macro. The $PYTHON_VERSION variable will be valorized with the detected
- # version.
