Rice 1.0.1 - Bug Fixes

Rice: Ruby Interface for C++ Extensions

Change Log:

  • Fixed x86_64 bit install bug with -fPIC
  • Fixed the tarball and zip file, they were missing an essential
    configuration file.

What is Rice?

Rice is a C++ interface to Ruby’s C API. It provides a type-safe and
exception-safe interface in order to make embedding Ruby and writing
Ruby extensions with C++ easier. It is similar to Boost.Python in many
ways, but also attempts to provide an object-oriented interface to all
of the Ruby C API.

What Rice gives you:

  • A simple C+±based syntax for wrapping and defining classes
  • Automatic conversion of exceptions between C++ and Ruby
  • Smart pointers for handling garbage collection
  • Wrappers for most builtin types to simplify calling code

How do you get Rice?

gem install rice

Note: Rice does require a C++ compiler. See the Documentation page for
more details.

How simple of a syntax?


#include “rice/Class.hpp”

class MyWrapper {
MyWrapper() { }

void doThis() { }
int doThat(int a, float b) { }


extern “C”
void Init_wrapper()
.define_method(“do_this”, &MyWrapper::doThis)
.define_method(“do_that”, &MyWrapper::doThat);


require ‘mkmf-rice’


require ‘wrapper’
c = MyWrapper.new
c.do_that(1, 2.0)

Building Ruby extensions have never been so easy!
