| 5 | # SYNOPSIS | |
| 6 | # | |
| 7 | # AX_PROG_PERL_MODULES([MODULES], [ACTION-IF-TRUE], [ACTION-IF-FALSE]) | |
| 8 | # | |
| 9 | # DESCRIPTION | |
| 10 | # | |
| 11 | # Checks to see if the given perl modules are available. If true the shell | |
| 12 | # commands in ACTION-IF-TRUE are executed. If not the shell commands in | |
| 13 | # ACTION-IF-FALSE are run. Note if $PERL is not set (for example by | |
| 14 | # calling AC_CHECK_PROG, or AC_PATH_PROG), AC_CHECK_PROG(PERL, perl, perl) | |
| 15 | # will be run. | |
| 16 | # | |
| 17 | # MODULES is a space separated list of module names. To check for a | |
| 18 | # minimum version of a module, append the version number to the module | |
| 19 | # name, separated by an equals sign. | |
| 20 | # | |
| 21 | # Example: | |
| 22 | # | |
| 23 | # AX_PROG_PERL_MODULES( Text::Wrap Net::LDAP=1.0.3, , | |
| 24 | # AC_MSG_WARN(Need some Perl modules) | |
