Ubuntu + Mysql5 + Rails3.2 に mysql2 をインストールしようとしてエラーが出た時の対処メモ。

Ruby: ruby 1.8.7 (2012-02-08 patchlevel 358) [x86_64-linux]
rvm: rvm 1.14.3 (stable)

mysql2 をインストールしようとしてエラー

mysql2 をインストールするため Gemfile に追記します。

Gemfile

1	gem 'mysql2'

いつも通り bundle install を実行するとエラーが発生して mysql2 がインストール出来ません。

Terminal
