Use Ruby-C buildpack if your Heroku application needs to call C code from Ruby.
To deploy a C extension with this buidlpack, put extconf.rb
in a root folder named c
.
To avoid version conflicts, order the Ruby-C buildpack to run AFTER the main Ruby buildpack.
$> heroku buildpack:add https://github.com/dextersealy/heroku-buildpack-Ruby-C.git
