Installing readline

Sometimes the readline library isn't compiled into Ruby by default. You will notice this when trying out the Rails console. Change to /home/<username>/.rvm/src/ruby-1.9.2-p136/ext/readline and run ruby extconf.rb to see the missing packages. Those are probably:

• libreadline5-devel
• libncurses5-devel

Install them by using Yast or Aptitude. Then run:

ruby extconf.rb
make
make install
