# Alt::Alien::FFI::System(3pm)

Simplified alternative to Alien::FFI that uses system libffi

## NAME

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

## VERSION

version 0.21

## SYNOPSIS

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

## DESCRIPTION

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.

## CAVEATS

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:

- do your own testing

  - skip tests

  - switch to the real Alien::FFI
