# SYNOPSIS
|
||
|
|
#
|
||
|
|
# AX_PROG_PERL_MODULES([MODULES], [ACTION-IF-TRUE], [ACTION-IF-FALSE])
|
||
|
|
#
|
||
|
|
# DESCRIPTION
|
||
|
|
#
|
||
|
|
# Checks to see if the given perl modules are available. If true the shell
|
||
|
|
# commands in ACTION-IF-TRUE are executed. If not the shell commands in
|
||
|
|
# ACTION-IF-FALSE are run. Note if $PERL is not set (for example by
|
||
|
|
# calling AC_CHECK_PROG, or AC_PATH_PROG), AC_CHECK_PROG(PERL, perl, perl)
|
||
|
|
# will be run.
|
||
|
|
#
|
||
|
|
# MODULES is a space separated list of module names. To check for a
|
||
|
|
# minimum version of a module, append the version number to the module
|
||
|
|
# name, separated by an equals sign.
|
||
|
|
#
|
||
|
|
# Example:
|
||
|
|
#
|
||
|
|
# AX_PROG_PERL_MODULES( Text::Wrap Net::LDAP=1.0.3, ,
|
||
|
|
# AC_MSG_WARN(Need some Perl modules)
