---|
| 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) |
