rbenv build failed on Ubuntu 14.04

Question

I've successfully installed rbenv (along with the build tools) on my Ubuntu 14.04 desktop, and that appears to be working fine, but as soon as I try to install ruby 2.1.1, the build fails:

daniel@grape:~$ rbenv install 2.1.1

I've done some searching for help with this issue, including following what is said here: https://github.com/sstephenson/ruby-build/wiki - but I've not had any joy.

Answer 1

UPDATE: Use Ruby 2.1.2, it fixes this issue.

14.04 is probably shipping with readline 6.3, which uses rl_hook_func_t instead of Function.

This bug has already been reported and fixed in Ruby (https://bugs.ruby-lang.org/issues/9578), but not released yet.

Until Ruby 2.1.2 comes out (which I assume will contain this fix), you can use a patch to properly support the new rl_hook_func_t method. Use this to install Ruby 2.1.1:

curl -fsSL https://gist.github.com/mislav/a18b9d7f0dc5b9efc162.txt | rbenv install --patch 2.1.1

UPDATE: Ruby 2.1.2, fixes this issue. If you need to patch ruby with Chef for another reason follow the example here.

Chef installation of Ruby 2.1.1 on to Ubuntu 14.04 using LWRP

Code to patch Ruby 2.1.1 on Trusty Ubuntu (14.04) using Riotgames rbenv cookbook - cut and pasted - no warranty :-) I have a wrapper cookbook which is tested on Ubuntu 14.04 (release 1.0.4). Easiest way is get this going is to clone the repository and converge it on test kitchen. The main gotcha is that the cookbook uses Berkshelf 3.1.1 and most people are probably on 2 still. The pasted code should work on Berkshelf 2.x and 3.1.1.

Berksfile
