secondary
If you are using another probe plugin (such as
Alien::Build::Plugin::Probe::CBuilder or
Alien::Build::Plugin::PkgConfig::Negotiate) to detect the existence of
a library, but also need a program to exist, then you should set
secondary to a true value. For example when you need both:
use alienfile;
# requires both liblzma library and xz program
plugin 'PkgConfig' => 'liblzma';
plugin 'Probe::CommandLine' => (
command => 'xz',
secondary => 1,
);
When you don't:
use alienfile;
plugin 'Probe::CommandLine' => (
command => 'gzip',
secondary => 0, # default
);
match
Regular expression for which the program output should match.
match_stderr
Regular expression for which the program standard error should match.
version
Regular expression to parse out the version from the program output.
The regular expression should store the version number in $1.
version_stderr
Regular expression to parse out the version from the program standard
error. The regular expression should store the version number in $1.
atleast_version
The minimum required version as provided by the system.
