Alt::Alien::FFI::System - (Deprecated) Simplified alternative to Alien::FFI that uses system libffi


version 0.23


 env PERL_ALT_INSTALL=OVERWRITE cpanm Alt::Alien::FFI::System


DEPRECATED: As noted below, this distribution was intended for use by system integrators packaging FFI::Platypus that didn't want to add the real Alien::FFI and its dependencies to their build chain. As of version 0.69, FFI::Platypus will use "pkg-config" and the system "libffi" if it is already installed, and skip the install of Alien::FFI. Thus, this module is now redundant. It may be removed from CPAN, but not before January 1st 2020.

This distribution provides an alternative implementation of Alien::FFI that is geared toward system integrators when libffi is provided by the operating system. It has no non-core requirements for runtime as of Perl 5.8. It now uses use Test::Alien for consistency with the original Alien::FFI.

It will NOT attempt to download or install libffi. If you need that, then install the original Alien::FFI instead.


Test::Alien is now part of Alien::Build, so if you need to run the tests, the prereqs aren't that much lighter than the real ALien::FFI, so you should consider:
