The decision to create a fork "originated here":https://github.com/rmagick/rmagick/issues/18#issuecomment-50022523, where you can read more about why it happened. h3.

Introduction RMagick is an interface between the Ruby programming language and the ImageMagick image processing library. h2(#prereq). Prerequisites *O/S* Linux, *BSD, OS X, Windows 2000, XP, Vista, other *nix-like systems. *Ruby* Version 1.8.5 or later. You can get Ruby from "www.ruby-lang.org":http://www.ruby-lang.org. Ruby must be able to build C-Extensions (e.g. MRI, Rubinius, not JRuby) *ImageMagick* Version 6.4.9 or later. You can get ImageMagick from "www.imagemagick.org":http://www.imagemagick.org. h2(#install). Installing RMagick h4. Installing via Bundler Add to your `Gemfile`: bc. gem 'rmagick' Then run: bc. bundle install h4. Installing via RubyGems Run: bc. gem install rmagick Require RMagick in your project as follows: bc. require 'rmagick' h2(#wrong). Things that can go wrong The "RMagick installation FAQ":https://web.archive.org/web/20140512193354/http://rmagick.rubyforge.org/install-faq.html has answers to the most commonly reported problems, though may be out of date. h4. Can't install RMagick. Can't find libMagick or one of the dependent libraries. Check the mkmf.log file for more detailed information. Typically this message means that one or more of the libraries that ImageMagick depends on hasn't been installed. Examine the mkmf.log file in the ext/RMagick subdirectory of the installation directory for any error messages. These messages typically contain enough additional information for you to be able to diagnose the problem. Also see "this FAQ":https://web.archive.org/web/20140512193354/http://rmagick.rubyforge.org/install-faq.html#libmagick. h4. Cannot open shared object file If you get a message like this: 
    $DIR/RMagick.rb:11:in `require': libMagick.so.0:
      cannot open shared object file: No such file or directory -
      $DIR/RMagick2.so (LoadError)
you probably do not have the directory in which the ImageMagick library is installed in your load path. An easy way to fix this is to define the directory in the LD_LIBRARY_PATH environment variable. For example, suppose you installed the ImageMagick library libMagick.so in /usr/local/lib. (By default this is where it is installed.) Create the LD_LIBRARY_PATH variable like this: 
        export LD_LIBRARY_PATH=/usr/local/lib
On Linux, see @ld(1)@ and @ld.so(8)@ for more information. On other operating systems, see the documentation for the dynamic loading facility. h2(#upgrade). Upgrading If you upgrade to a newer release of ImageMagick, make sure you're using a release of RMagick that supports that release. It's safe to install a new release of RMagick over an earlier release. h2(#samples). More samples You can find more sample RMagick programs in the /example directory. These programs are not installed in the RMagick documentation tree. h2(#bugs). Reporting bugs Please report bugs in RMagick, its documentation, or its installation programs to me via the bug tracker on the "RMagick issues page":https://github.com/gemhome However, I can't help with Ruby installation and configuration or ImageMagick installation and configuration. Information about reporting problems and getting help for ImageMagick is available at the "ImageMagick web site":http://www.imagemagick.org or the "ImageMagick Forum":http://www.imagemagick.org/discourse-server. h2(#contact).
