¿Cómo compilo / crear una extensión de rubí a través de C?

Question

Quiero crear una extensión de rubí que utiliza c. Pero cuando compilo con gcc, estoy consiguiendo este error:

gcc rubyext.c -orubyext -I /usr/local/include/ruby-1.9.1/

¿Lo he hecho mal? Mi archivo rubyext.c sólo tiene una línea de código:

#include <ruby.h>

Cualquier ayuda es muy apreciada.

Por supuesto, no se puede simplemente incluir los archivos de cabecera, que debe enlazar con la biblioteca de Ruby.

Este capítulo de la piqueta.

También dude en ver algunos de mis repos en GitHub , escribo una gran cantidad de extensiones C.

Envíame un mensaje en ese sitio si necesita ayuda.
