Come compilo / creare un'estensione rubino che usi c?

Question

Voglio creare un'estensione rubino che utilizza c. Ma quando ho compilare con gcc, sto ottenendo questo errore:

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

l'ho fatto di sbagliato? Il mio file rubyext.c ha una sola riga di codice:

#include <ruby.h>

Ogni aiuto è molto apprezzato.

Naturalmente non si può semplicemente includere i file di intestazione, si deve collegare alla libreria Ruby.

Questo capitolo dal Piccone.

Inoltre, sentitevi liberi di in rassegna alcune delle mie pronti contro termine su GitHub , scrivo un sacco di estensioni C.
