NAME

libretro-core.eclass - Simplify libretro core ebuilds

DESCRIPTION

The libretro eclass is designed to streamline the construction of ebuilds for Libretro core ebuilds.

Libretro cores can be found under https://github.com/libretro/

They all use the same basic make based build system, are located in the same github account, and do not release named or numbered versions (so ebuild versions for git commits are keys). This eclass covers those commonalities reducing much duplication between the ebuilds.

SUPPORTED EAPIS

EXAMPLE

EAPI=7

LIBRETRO_CORE_NAME="2048"
LIBRETRO_COMMIT_SHA="45655d3662e4cbcd8afb28e2ee3f5494a75888de"
KEYWORDS="~amd64 ~x86"
