cを使用するruby拡張機能を作成したいと思います。しかし、gccでコンパイルすると、次のエラーが発生します。

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

私はそれを間違えましたか？私のrubyext.cファイルには1行のコードしかありません：

#include <ruby.h>

どんな助けでも大歓迎です。

もちろん、ヘッダーファイルだけをインクルードすることはできません。Rubyライブラリにリンクする必要があります。

つるはしからこの章を読んでください。

また、githubで私のリポジトリのいくつかを自由に閲覧してください。私はたくさんのC拡張機能を書いています。

ヘルプが必要な場合は、そのサイトで私にメッセージを送ってください。
