# ruby-build ruby-build provides a simple way to compile and install different versions of Ruby on UNIX-like systems. ### Installing ruby-build $ git clone git://github.com/sstephenson/ruby-build.git $ cd ruby-build $ ./install.sh This will install ruby-build into `/usr/local`. If you do not have write permission to `/usr/local`, you will need to run `sudo ./install.sh` instead. You can install to a different prefix by setting the `PREFIX` environment variable. If you only intend to use ruby-build via rbenv then you can install it locally as a plugin: $ mkdir -p ~/.rbenv/plugins $ cd ~/.rbenv/plugins $ git clone git://github.com/sstephenson/ruby-build.git And if you're using Homebrew, you can just $ brew install ruby-build to get the latest release, or $ brew install --HEAD ruby-build to pull the latest from git. ### Installing Ruby To install a Ruby version, run the `ruby-build` command with the path to a definition file and the path where you want to install it. (A number of [built-in definitions](https://github.com/sstephenson/ruby-build/tree/master/share/ruby-build) may be specified instead.) $ ruby-build 1.9.2-p290 ~/local/ruby-1.9.2-p290 ... $ ~/local/ruby-1.9.2-p290/bin/ruby --version ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.0.0] You can use it with [rbenv](https://github.com/sstephenson/rbenv): $ ruby-build 1.9.2-p290 ~/.rbenv/versions/1.9.2-p290 ruby-build provides an `rbenv-install` command that shortens this to: $ rbenv install 1.9.2-p290 ### Version History #### 20120423 * Improved error messages when dependencies are missing. * XCode 4.3+ may be used to build 1.9.3-p125 and later. * Updated all Ruby 1.9.2 and 1.9.3 definitions to RubyGems 1.8.23. * Added definitions for REE 1.8.7-2012.02 and 1.8.7-2009.10. * Added definitions for JRuby 1.6.7. * Added definitions for Ruby 1.9.2-p318, 1.9.2-p320, and 1.9.3-p194. #### 20120216 * Added definitions for REE 1.8.7-2011.12 and 1.8.7-2012.01. * Added definitions for JRuby 1.6.5.1 and 1.6.6. * Added definitions for Ruby 1.8.7-p358 and 1.9.3-p125. * Updated the readme with instructions for installing ruby-build as an rbenv plugin. #### 20111230 * Added a definition for MagLev 1.0.0. * Added support for overriding `make` options with the `$MAKEOPTS`/`$MAKE_OPTS` environment variable. * Removed RubyGems installations from JRuby definitions in favor of the bundled RubyGems versions. * Added a `before_install_package` hook. * Added definitions for REE 1.8.7-2009.09 and 1.8.7-2010.01. * Added definitions for Ruby 1.8.6-p383, 1.8.7-p302 and 1.8.7-p357. * Updated the JRuby 1.7.0-dev snapshot URL. * Changed the GCC detector to look for `gcc-*` anywhere in the `$PATH`, not just `/usr/bin`. #### 20111030 * Added a Ruby 1.8.7-p334 definition. * Renamed the 1.9.4-dev definition to 2.0.0-dev to reflect the new version numbering scheme. * ruby-build now automatically displays the last 10 lines of the error log, if any, when a build fails. * Improved the GCC detection routines and added a more helpful error message for Xcode 4.2 users. * JRuby installation no longer requires the install prefix to exist first. * You can now pass `$CONFIGURE_OPTS` to the REE definitions. * Added a JRuby 1.6.5 definition. * Added a Ruby 1.9.2-p180 definition. * Added a Ruby 1.9.3-p0 definition. #### 20110928 * ruby-build now uses the `--with-gcc` configure flag on OS X Lion. * Added definitions for REE 1.8.7-2010.02 and 1.8.6-2009.06. * Modified `rbenv-install` to run `rbenv rehash` after installation. * Added a Ruby 1.9.3-rc1 definition. * Updated the JRuby defintions to install the `jruby-launcher` gem. * Updated the rbx-2.0.0 definition to point to the master branch. * Added a jruby-1.7.0-dev definition. * Added a Ruby 1.9.4-dev definition. #### 20110914 * Added an rbx-2.0.0-dev definition for Rubinius 2.0.0 from git. * Added support for setting `./configure` options with the `CONFIGURE_OPTS` environment variable. * Added a 1.9.3-dev definition for Ruby 1.9.3 from Git. * Added support for fetching package sources via Git. * Added an `rbenv-install` script which provides an `install` command for rbenv users. #### 20110906.1 * Changed the REE definition not to install its default gem collection. * Reverted a poorly-tested change that intended to enable support for relative installation paths. #### 20110906 * Initial public release. ### License (The MIT License) Copyright (c) 2011 Sam Stephenson Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
