我的主数据库是本地mysql数据库，但是我想偶尔直接在我的应用程序代码中连接到Oracle数据库。Ruby on Rails Oracle数据库连接
oracle数据库位于另一个RHEL服务器上。
我unsuccessfull尝试安装红宝石OCI8宝石（错误：未能建立宝石原生扩展）
我想知道oracle数据库是否是为了使用这个宝石，或者如果本地有更好的方法来实现这一点。

我检查了mkmf.log文件：

这已经离开了我最初的问题的整个点。我想知道OCI8插件是否适用于外部数据库，因为我似乎无法在任何地方放置主机名 – Rumpleteaser 2010-12-22 05:19:37
“C编译器无法正常工作。”似乎看起来像一个问题。我尝试下载源代码并制作它。 – Rumpleteaser 2010-12-22 05:53:17
