# SYNOPSIS
|
||
|
|
#
|
||
|
|
# AX_PROG_FLEX_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
|
||
|
|
#
|
||
|
|
# DESCRIPTION
|
||
|
|
#
|
||
|
|
# Makes sure that flex version is greater or equal to the version
|
||
|
|
# indicated. If true the shell commands in ACTION-IF-TRUE are executed. If
|
||
|
|
# not the shell commands in commands in ACTION-IF-TRUE are executed. If
|
||
|
|
# not the shell commands in ACTION-IF-FALSE are run. Note if $FLEX is not
|
||
|
|
# set (for example by running AC_CHECK_PROG or AC_PATH_PROG) the macro
|
||
|
|
# will fail.
|
||
|
|
#
|
||
|
|
# Example:
|
||
|
|
#
|
||
|
|
# AC_PATH_PROG([FLEX],[flex])
|
||
|
|
# AX_PROG_FLEX_VERSION([2.5.39],[ ... ],[ ... ])
|
||
|
|
#
|
||
|
|
# This will check to make sure that the flex you have is at least version
|
||
|
|
# 2.5.39 or greater.
|
||
|
|
#
|
||
|
|
# NOTE: This macro uses the $FLEX variable to perform the check.
