推荐答案

您有3种可能：

加载库。即使它有点棘手，你可以决定编写自己的加载器和绑定你的C ++库在Ruby。
这是通过使用扩展模块来完成的。您可以在这里找到一个全面的教程： http://www.rubyinside.com/how-to-create-a-ruby-extension-in-c-in-under-5-minutes-100.html

1) Ruby is able to load libraries. Even if it is a bit tricky, you can decide to write your own loader and bind your C++ library in Ruby. This is done using what is called an extension module. You will find a comprehensive tutorial here: http://www.rubyinside.com/how-to-create-a-ruby-extension-in-c-in-under-5-minutes-100.html

2）您可以使用工具来生成C ++库周围的Ruby包装器。以SWIG为例（ http://www.swig.org/ ）。
您只需要创建一个swig特定语法的文件并提供给SWIG。

2) You can use a tool that will generate the Ruby wrapper around your C++ library. Look at SWIG for example (http://www.swig.org/). You just have to create a file in a swig-specific syntax and provide it to SWIG. It will then be able to generate the wrapper for many languages, Ruby included.

3）您可以选择使用中间件，例如CORBA / ICE /任何。如果你只想调用一些C ++函数，它可能是有点overkill，但它将允许你远程调用函数，或隐藏网格后面的中间件。

3) You can choose to use a middleware, such as CORBA/ICE/whatever. It may be a bit overkill if you only want to call some C++ functions, but it will allow you to remote call the functions, or "hide" a grid behind the middleware.
