Description
The mkmf library that ships as part of the Ruby standard library is not meant for use as an internal library. It's strictly designed for building C extensions. It's huge, its methods sit in a global namespace, it contains many methods you don't care about, and it emits stuff to $stdout that cannot easily be disabled. Also, the source code is monstrous.
The mkmf-lite library is a module, it's small, and it's designed to be mixed into classes. It contains a handful of methods that, most likely, will be used in conjunction with FFI. Also, the source code is quite readable.
It does not package C extensions, nor generate a log file or a Makefile. It does, however, require that you have a C compiler somewhere on your system.
As of version 0.6.0 it memoizes the results of any checks that you make since they wouldn't ever change without requiring a reboot/restart of your server, container, etc, anyway.
Known Issues
