@node ax_prog_ruby_version
@unnumberedsec ax_prog_ruby_version
@majorheading Synopsis
@smallexample
AX_PROG_RUBY_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
@end smallexample
@majorheading Description
Makes sure that ruby 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 $RUBY is not set (for example by
running AC_CHECK_PROG or AC_PATH_PROG) the macro will fail.
Example:
@smallexample
AC_PATH_PROG([RUBY],[ruby])
AC_PROG_RUBY_VERSION([1.8.0],[ ... ],[ ... ])
@end smallexample
This will check to make sure that the ruby you have supports at least
version 1.6.0.
NOTE: This macro uses the $RUBY variable to perform the check.
AX_WITH_PROG([RUBY],[ruby],[VALUE-IF-NOT-FOUND],[PATH]) can be used to
set that variable prior to running this macro. The $RUBY_VERSION
variable will be valorized with the detected version.
