Similar to Boost.Python and pybind11, it minimizes boilerplate by automatically handling type conversions between C++ and Ruby, exception conversions, smart pointers for garbage collection, and wrappers for built-in types. It requires C++17 or later and supports Windows, macOS, and Linux. Version 4.x is the current header-only release, installable via `gem install rice`. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What C++ standard and Ruby version does Rice 4.x require? Rice 4.x requires C++17 or later and Ruby 2.7 or later. It is a header-only library, so it does not need separate building and can simply be included in a C++ project. It is tested on Windows with MSVC and Mingw64, MacOS with Xcode/clang, and Linux with g++. _daily.dev surfaces practical setup requirements like these for developers evaluating C++ to Ruby binding libraries._ ### How do I install the Rice library for wrapping C++ classes in Ruby? Install it with the command 'gem install rice'. Since Rice is header-only, after installing you include headers such as rice/rice.hpp and rice/stl.hpp directly in a C++ project rather than linking a compiled library, and running rake regenerates these combined headers and runs the test suite. _developers building Ruby-C++ bindings can find setup guidance like this through daily.dev._ ## Similar posts on daily.dev - [A Journey from Pybind11 Envy to Wrapping OpenCV – CFIS](https://daily.dev/posts/a-journey-from-pybind11-envy-to-wrapping-opencv-cfis-wnyu6zadi) · Ruby Flow · 0 upvotes · 0 comments - [The Ruby Bindings Every Rails Developer Should Know](https://daily.dev/posts/the-ruby-bindings-every-rails-developer-should-know-rgkbr7mbz) · RUBYLAND · 0 upvotes · 0 comments - [mruby/mruby: Lightweight Ruby](https://daily.dev/posts/mruby-mruby-lightweight-ruby-e7cvnrejh) · Hacker News · 0 upvotes · 0 comments - [Ruby Programming Language](https://daily.dev/posts/ruby-programming-language-xlmujxgbj) · Lobsters · 3 upvotes · 0 comments - [FFI: How Ruby Talks to C](https://daily.dev/posts/ffi-how-ruby-talks-to-c-ziuiprg0q) · Ruby Flow · 0 upvotes · 0 comments --- Tags: [#c](https://daily.dev/tags/c), [#ruby](https://daily.dev/tags/ruby), [#c++](https://daily.dev/tags/c++) [View this post on daily.dev](https://daily.dev/posts/github---ruby-rice-rice-ruby-interface-for-c-extensions-qm5qyka11) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"GitHub - ruby-rice/rice: Ruby Interface for C++ Extensions","url":"https://daily.dev/posts/github---ruby-rice-rice-ruby-interface-for-c-extensions-qm5qyka11","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/github---ruby-rice-rice-ruby-interface-for-c-extensions-qm5qyka11"},"datePublished":"2026-07-11T08:31:06.422Z","dateModified":"2026-09-13T21:17:08.486Z","description":"Rice is a header-only C++ library that simplifies creating Ruby bindings for C++ libraries and embedding Ruby in C++ projects.
