title: Installing mysql2 gem
body: <p>I have tried installing mysql 2 gem to start building my rails app. I have Rails 4.0.4 and Ruby 1.9.3p545. I've been getting the same error after working on it for several days. I tried installing mysql 32 bit version again to make sure I had the right version with the right connector, moved my libmysql.dll and libmysql.lib to my ruby/bin folder and tried several other means of making it work that I found online. None of them have worked for me. The below is what I have. I would appreciate any help that allows me to finally install the mysql2 gem.</p>
