NAME

Alien::XGBoost - Alien package to find, and build if necessary XGBoost dynamic library

VERSION

version 0.05

SYNOPSIS

    use Alien::XGBoost;
    use FFI::Platypus;

    my $ffi = FFI::Platypus->new;
    $ffi->lib(Alien::XGBoost->dynamic_libs);
    $ffi->attach(XGBGetLastError => [] => 'string');
    my $error = XGBGetLastError();

DESCRIPTION

Alien package to find, and build if necessary XGBoost dynamic library.

This module is to be used by other modules that need the XGBoost dynamic library available, indeed I've made this for AI::XGBoost.

If you only want to use XGBoost in your perl programns, just use AI::XGBoost and forget this module. If you want to make other XGBoost wrappers or use from XS then continue reading.

By now there is no support for compiling your modules against XGBoost. Just using the dynamic library via FFI::Platypus or NativeCall.

Troubleshooting

The "instructions" to build and install as a module are in the alienfile.

Lots of things can go wrong, and in that case, I'm glad to help, just open an issue https://github.com/pablrod/p5-Alien-XGBoost.

But this information could be useful:

Downloading

XGBoost doesn't make releases often https://github.com/dmlc/xgboost/releases (last one from 2016) So I'm cloning branch master.

XGBoost uses git modules, so I need a recursive clone.

Installing

XGBoost cmake doesn't provide a install target for the generated Makefiles, so this module is copying the dynamic library and the xgboost command to the module share dir

If installation is succesfull you can query the module Alien::XGBoost to know where is the dynamic library and command in your system
