Error installing JRuby with RVM on OS X 10.8

Question

I'm running into an error when installing JRuby in RVM for OS X 10.8, terminal output is below when trying to install:

$ rvm install jruby --debug

The nailgun.log looks like this:

[2012-11-01 00:09:18] jruby_install_build_nailgun

    typeset _result;

So it looks like there is a problem calling configure, config.log is below:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by ng configure 0.7.1, which was
generated by GNU Autoconf 2.61.  Invocation command line was

  $ ./configure --prefix=/usr/local/rvm/rubies/jruby-1.7.0

Anyone have any idea what's going on? Tried for hours looking round different forums with no luck. Thanks.

Answer 1

it is not required to build nailgun in jruby 1.7.0, you can use rvm head where this step was already removed:

rvm get head
rvm reinstall jruby

Answer 2

I've managed to install jruby with mac osx 10.8 without any problem.

$ rvm install jruby
jruby-1.7.0 - #downloading jruby-bin-1.7.0, this may take a while
depending on your connection... jruby-1.7.0 - #extracting
jruby-bin-1.7.0 to /Users/guy/.rvm/src/jruby-1.7.0 jruby-1.7.0 -
extracted to /Users/guy/.rvm/src/jruby-1.7.0 jruby-1.7.0 - #nailgun jruby-1.7.0 -    #installing to /Users/guy/.rvm/rubies/jruby-1.7.0
jruby-1.7.0 - #importing default gemsets (/Users/guy/.rvm/gemsets/)

It seems that configure is failing, which might be that your gcc is outdated or for some reason not working properly. Do you have Xcode installed and add the command line tools? This should fix your gcc problem. If you don't want to get Xcode installed you can install gcc with homebrew or the likes.
