How do I compile Readline support into Ruby

irb, readline, ruby

Solution

- Install `readline` to `/usr/local`

- Recompile ruby from scratch and use the `--with-readline-dir=/usr/local` switch

or if you have downloaded the ruby sources earlier and built it by hand,

- Go to the `ext/readline` folder of your ruby source tree

- Type `ruby extconf.rb` and then run the `make && make install` procedure for ruby.

Problem

My version of ruby was compiled with `editline` (on os x) and I miss the features of `readline` in `irb`. How do I recompile ruby with `readline` support?
